[Q] LG Vortex stuck at boot screen, can anyone help to get into recovery mode? - Android Q&A, Help & Troubleshooting

I rooted my LG recently to get rid of the crapware that was on by default. But, of course, it wasn't enough for me. I tried to flash a new ROM, and everything went to hell. Now the boot screen won't go past the LG logo. Does anyone know how to reset the device back to factory standard?
Hard reset doesn't work (home + volume down / up + power)
Windows/Linux doesn't see the plugged in device.
adb doesn't see the plugged in phone
I tried to put cyanogenmod on, which was probably a bad idea. I've heard that this problem may be irreperable, and I just want to see if there's any way to avoid having to try and deal with Verizon.
Before flashing (using rom manager), I made sure to choose the backup the current rom option. I've heard that I should be able to restore that backup, but there's no way to actually connect to the phone at the moment.
Any help would be appreciated.
EDIT: I've gained access to the SD card by plugging it into an external reader. I can see the recovery image that clockwork made. How can I get the phone to boot into it?

Yes, please do post it. I attempted the LOL 1.4.2 rom for Optimus One and am now in this same situation. I have a working rom on my sd card if I could just get to the recovery screen.

I read a few posts mentioning that they were able to reset their phone using their ac adapter, but I hadn't any luck trying it that way, until a good friend of mine used some google-fu to determine that the order in which you do things matters! Here's the steps I had to take:
Remove battery from phone
Begin holding power, volume down and home
Plug phone into ac power WITHOUT LETTING GO OF BUTTONS (wasn't easy for me either)
Phone should boot into recovery (in my case the custom recovery)
You can let go of those buttons now
Install battery
Flash your phone and rejoice!

THANK YOU! The part I wasn't getting was the plugging into A/C while holding the buttons down...you're a lifesaver!!!

This did not work for me. I tried putting the phone into recovery mode, but it still just booted up as normal. I'm running out of ideas and patience here...

Lgtools
estoy en la misma situacion, yo cuento lgtools de Setool Box3, la cual soporta lectura y escritura de sistema de Lg vortex vs660, pero no logro que me lo detecte para cargar firmware completo, mi problema fue que flashe el recovery desde el ROM MANAGER y se queda en el logo.

I recovered my friend's phone using the following procedure
I just fixed a friends phone so I thought I would share in case it helps anyone. This is for the LG Vortex on Verizon. Might work for other carriers.
Download and install the Vortex drivers from LG's mobile support site www dot lg dot com/us/support/mc-support/mobile-phone-support.jsp
Download and install the LG Mobile Update utility www dot lg dot com/us/support/mc-support/mobile-phone-support.jsp
Run the LG Update app and make sure your phone is up to date. You can also try the Recover option if it can't update. This phone's firmware was up to date.
Install the Android SDK from google.
Access backdoor recovery through ADB
Plug phone in to laptop usb
Press and hold down the volume down key, the home key, and the power key at the same time. Keep them pressed until the screen goes black then you can release. If it goes in to some other visible recovery you can simply skip some of these steps
At this point your computer should start to recognize the phone and go through a series of driver installs
Once that is complete you should be able to go to the command line and enter the ADB shell
Follow the procedure at the following link to get the clockworkmod recovery installed
androidforums dot com/getitnowmarketing/330813-all-one-recovery-thread.html
Once you are able to boot in to clockwork, immediately do a backup. Then clear your data, cache and dalvik cache, then reboot. This won't always work, but many times it will allow you to boot a ROM that gets stuck booting (like this phone). If that doesn't work then just go back to recovery and utilize a manual ROM flashing procedure you can find on many forums.
This process worked great on this phone so hopefully someone else may have similar luck.
Sorry for cutting up the links, i'm new to the forum. Just replace the "dot"s with . obviously.

Try this worked for me
Here's a different method of unbricking your vortex V660. With limited support and methods for this device it seems to make everything more complicated in finding a soluttion around certain but complex problems. I tried to use some of the other metheds listed on android central and XDA...such as, taking the battery out, holding home, vol -/+ and power key at the the same time the phone back in while it was connected to the computer. I wasnt able to get anywhere with these methodes,I also thought qbout trying the unbutu method to unbrick it then I thouht that was to much of an effott. I read all the comments and differnt methods and decide it wasn't worth the risk, I re-woked a different method for unbricking, there's prob about a 90% possibility of it working for your LG.This just happenes to be my own solution or workaround if you find yourself screwed like i did with no type of support.
The reason this didn't work was because I didn't have cwm installled nor did the phone have the original firmware installed, my mistake, I wiped that off too, happenes when you have to much to drink lol, the hard reset buttons were a no go as well since they take you into cwm or the orignal firware from verizon {all mine did was take me to a black screen because there was nothing there for it to load.} Some how or another all was wiped clean and I was in a catch 22 while being bricked. I found the vs660 recovery firmware but I knew i really didn't need to install it so i didn'nt.The bricked happened after I installed Titanium Backup then uninstalled launcher pro so then I restarted and got to the point where the ring Fire or boot animation was trying to load ,and it just just hung there. I don't care for the app launcher pro I would rather use awd launcher, if u haven't noticed you have to pay for the pro version of launcher pro just to rezize widets, so im wondering why this app was added to the Rom Cyan7.2 in the first place. So with no cwm, no stock image, and no way to make an sdcard boot into m to unbrick it my hopes and last resort were to pray that.I had usb debugging enabled.
First thing you have to install is called jdk-7u3-windows-i586] the other file called installer_r_windows wont't allow you to install until the install of JDK is complete.It'd ok to lauch the installer-r26-windows first because it ill drnf you directly to the site to downloadthe JDK file. Install these two programs first, (google how to ADB tutoria if needed? So after downloading that you will need to download the right drivers (for the voerex) Software name (Driver_WHQL_ML_Ver_4.9.7_All_Win7_LGEAll)(Google Search It)} There's 1 other thing we to have to do before seeing if your decice is listed in ADB. We need to add a line to the Envioronment Varibles section under System Variables at the bottom. Here's how to get there in Win7, right click on my computer, advanced tab, at the bottom Environmental Variblesm, click itlook down under system variables and scrooldowm until you see something called Path and add this line to end of it, ofcourse clickit edit then copy and past his line including the semicolon ;c:\android-sdk-windows\tools;c:\android-sdk-windows\platform-tools now save it amd exit. The reason this is done is so we won't have to contantly navigate through cmd prompt to the directory and list commands. This is prevent you from have to navigate to the folder evertime u want to run the program or any cmds. Now that were all setup lets connect to you phone's data cable to the pc and the phone, and again make sure abd debugging is enabled. Settings, applications, development, the check in the box for debugging, if it's not enabled you will get the turn on usb feature your phone so not what we want. Now opem the cmd prompt run the cmd cd.. then cd.. now you should C:\>, you can run the cmd adb devices now hit enter and you you see a long 14 to 16 digit # then that means your devices is succesfully connected and talking to your PC.That long # should be your MEID HEX# to your phone if you dont see that and you see somethine else then go back though the guide to see if you missed something during setup. If setep properlly in the cmd prompt type adb devices and your phone will automactically show its long#, after that type the cmd adb reboot at which point through cmd promt the device will reboot itself. Here a little secret just because you don't have youtr verison's orignal firmware nor a working ROM on you phone such as froyo 2.2.1 or 2.2.2 doesn't mean anything, you are still rooted and wont have to downgrade to 2.2.1. Side note ( z4root didn't work for my lg vortex, I tried gingerbreak 1.10 and later gingerbreak 1.2 which both worked just fine, z4root just hung on my phone, sry i bounced off topic but i took me 24 hrs of troubleshooting till I got it back up and running.
This method I would say this only applies to the ones that don't have cwm installed on their internal drive it acccidently wiped the original firware off their phones and don't have anything to boot into. I don't have the orignal verizon stock installed, essentially you hit the same buttons on the phone to do a hard reset or to boot into recovery as you normally would. If you neiher on your phone then ADB is your saving grace. Another tutorial I seen was something about installing ubuntu lunux, it just seemed liked to muck work for me, plus I didn't want linux on my box anyways, not til im ready for building a linux kluster later.
let get started...go and download the Adb software which is called Android-debug-brigde...you will also have a visual demo to guide you through the setup) (ADB file) name installer_16-windows,install this this file last to the root of C:/ once done its location will look like this c:\android-sdk-windows ( this is important to make sure you extract the exe to C:/android-sdk-windows (you can take advantage of youtube's a great resourse for viual walkthroughs} or google it,.i have had to do i know's our there , well if you more of a reader search google or xda it will breakdown the core or the installing of the actual files can't post links here but you have to post a minimum if 8 tines b4 you can post links outside this site.
Once all that's setup you need to confirm that its linked properly. Phone off or on during this process I wouldn't think it matters,my devices were on, so conntect you data cable to you usb port and the other end to your phone where you normally power it. This is the time you better hope USB Degugging is enabled. If it is you will see the little Android character and something that looks like a usb icon in the status bar of your phpne, so if you pull down your status bar is will tell your if you are in use debugging mode,. in the status bar depending on where your bricked. if you are in a booploop all its going to do it make that noise of connecting and disconnting. you may have to find fifferent approach to fix it, only solution I can give you if to try home, vol +, and power down til you get a black screen and hope it hangs there there long enough to so you clear it. So it this aproach words on a bootloop let me know in the comments.
Once everything looks good open up your device manager
Just under your computer mame u should see somethig called ADB Interface
under that from the drop arrow you will see android plactform sooner single ADB Interface, click on that and you will see android plattform sooner single ADB Interface, then under modems you will see LGE Android Platform USB Modem, and last at the bottom your youw will see universal serial bus controllers, select that and you should your see LGE Android Platform Composite USB Device, If you see all that that your 100% convered
Now to get your phone out of that nasty brick and we don't need need any firware or Roms to do it...
Open cmd prompt, type cd.. then cd.. again now your in C:\>
now type cd android/sdk/system (note the CD just means change directories) now were in the folder called c:\android-sdk-windows
From this directory is where were going to run our commands since we can't do it in cwm.
type wipe system and hit enter
wipe system you will see a alot of errors like it didnt do anything but that's ok next step
type wipe data hit enter
once done pull cable reboot phone wait to it to come up to where to you have to touch the andoid like your setting up the phone for the first time again, warming u more that lickly will get an FC during setup and it will brick again on the same screen. Repeat wipe system and wipe data again, the gp though the setup on the phone again, if have have another FC one last time so again wipe system then wipe data, this time there shouldn't be anymmore FCs, I have to go through wipe system and data 3 times b4 the FC's stooped and I will able to to to the activaton screen > My phone is a refurb so if would let me past the activation screen this time as when im loading up in CM7. last issue I faced was the accivation screen, Now I did some reading on this and there are a couple of thing you can one of which worked for me., You can tap the four counrers in the clockwise direction which didn't work for me, or what did, I click activcate then entered *228 then hung up, avtivate again *228 hungup, then activate again,*228 hugnup and this time I was able to skip activation anb and was again to load cwm and flash my phone, so its not longer bricked and I dont have to worry about the avivation all though it will comes up U can stip it and It wont keep me from me phone, I have VIOP setup over my 4g LTE, any questions about this type hack just let me know, ( I have an 18 Page Paper about how it works how to set it up, its free and no download charge for the APK) and I will post it. Forwaring the paper 18 pages long and pretty in depth, I dont explain the backend of how it works but just a little, its mainly the frontend and to set it up and all the routing.

Vortex sux
Okay ... so my vortex is nothing more than a paper weight at the moment. When I turn it on, the LG screen comes on for 3 seconds, then the screen goes blank, then it starts over again. I can't turn it off after it starts its boot loop. I have tried using the recovery keys, and nothing. If I plug it into the computer it will turn on and do the loop over and over again, and i still cant power off. I have a 4gb micro with cwm recovery, but i do not know how to get this phone to boot into the cwm recovery. your help would be appreciated.

Here's what worked for me

I was in a similar situation and was able to get to recovery by taking out the battery, holding down the buttons required to get into recovery and then while holding down the buttons, plugging the phone into the wall charger. Once it was in recovery I put the battery back in and flashed back to a known good rom. Not sure why this worked over just turning it on normally, but it's worth a shot.

Please help me. I'm desperate.
EDIT: I DID A HARD RESET AFTER FLASHING. IT WORKED!
Hello all,
since I'd spent a couple of hours trying to solve this problem, I figured I'd say a few sentences about this as at least I myself would have found it useful...
This is regarding the LGP500 / LG Electronics P500 Android phone. For similar phone users: if you know your key combinations for hard reset and Emergency modes AND you know which ROM image to use (and have access to it), this might help your Android phone as well.
After somehow having managed to screw up the Android OS / /system (unrooted the phone (this went well) and then did some extensive modification/experimentation with the system; I think it might have been terminating the abd terminal while insmod'ing a faulty kernel module that screwed things up),
I ended up with a phone that would only show the LG logo during boot time - not even an Android logo (as the user above had had). Obviously, the phone did not respond to any USB connection queries; the hard reset (keep HOME+VOLUME_DOWN pressed, press Power) would end up splashing a pretty reset image/logo, but would then fall back / reboot into the LG logo.
In the end, the procedure turned out to be rather simple and practically as explained above:
1) make sure your host OS recognizes the phone - install the phone driver in Windows (use "LGMobile update", might need to enter your IMEI OR (Model AND Serial num.); under the battery) or update /etc/udev rules in Linux (I didn't want to further experiment with a windows-program firmware updater under Wine, so used Windows for this); OSX doesn't need any action AFAIK;
2) make sure the phone is off. Remove and re-insert battery if needed;
3) while holding RETURN+VOLUME_UP (not HOME, but RETURN (the right key out of the two in the center), and not VolDOWN, but VolUP this time), press Power. After some time, the phone should display a bright yellow screen with the text "Emergency mode." (**);
4) connect the USB. You have to act fast now, as the phone will only wait for some seconds before rebooting back into agony. as far as I understand, it is now just waiting for the new ROM image;
5) having followed the steps in the previous post above regarding setting up KDZ_FW_UPD and having selected your ROM image, make sure you set the mode right - the only difference from above is that now, you have to choose "Emergency" instead of "DIAG.";
6) Hit "Launch software update." If it hangs and becomes unresponsive for a while, that's a good sign. It should later start dumping log data into the window. Obviously, don't disconnect (THEN you might end up with a bricked phone..) etc.;
7) After everything finishes, you might need to restart the phone once more and do a hard reset (as mentioned above); but might not be needed.
(**) - if after trying a lot of times with the RETURN+VOL_DOWN -> PowerUp combination (and inserting the USB cable afterwards) you end up not arriving at a bright yellow screen, you might be screwed. At least this procedure relies on the assumption that the Emergency mode is working. But as far as I understand, you can completely screw your OS/ROM up and still have the Emg. mode available; so check thoroughly before making any conclusions.
Sorry for the long post, but maybe this will save someone some time/money.
Regards,
Kostas.

[Q] Boot Loop on LE I/O 10.1 need help!

Hey Guys, could sure use your help... i updated my 10.1 le yesterday and that went thru fine. Later on i was playing and watching youtube and it sent my tablet into a boot loop and i cant seem to fix it. any help would be appreciated thanks in advance.
Mine did the same thing when i was streaming music. Not even Odin brought it back. I used adb to reboot into stock 3e recovery and wipe data/factory reset it, then used Odin to grt back to 3.0.1. Then i just redownloaded the 3.1 update. Hope that helps

right now im having problems with adb listing the devices. adb is installed. it keeps saying that i need some APX drivers???
Drivers are here:
http://www.samsung.com/us/support/owners/product/GT-P7510UWYXAR
I had the same problem. This is what i did. Since I had already rooted my tablet, I already had in my laptop ADB and the driver for the tablet. If you don't have these 2 things, I suggest you go to the development section of this forum, look for the insrltructions on how to root, and download what you need.
I connected my tablet then went into cmd mode (DOS MODE), then typed adb reboot recovery. From there the tablet rebooted into recovery. I then wiped data and cache. Then I rebooted and it went fine, no more bootloop. In settings I noticed that it had reverted back to 3.0.1 so I just did update again. Since then my tablet has been smooth as butter.

For those not too comfortable with ADB, I just installed PDAnet (for the fastboot drivers) and after booting to fastboot (holding power and the volume down button and selecting the USB symbol) I used the "fastboot -w" command in CMD.exe to wipe the device.
Its rather strange that a lot of people are having problems. Mine started after getting an error turning on the WIFI chip. Thank god for Titanium Backup's option to sync with Dropbox. Hope this helps.

THANK YOU!! Your suggestion of installing PDAnet saved me! I was having a hell of a time trying to get the right drivers so my computer would recognize the tablet has an adb device. After installing PDAnet, it was a cinch. Then I reflashed everything, wiped userdata and cache, and rebooted (I followed the instructions found here: http://forum.xda-developers.com/showpost.php?p=14600617&postcount=111) Now my tab is working again and I was getting ready to ship it off to Samsung so they could re-flash it for me.

Obviously I have installed adroid-sdk and download fastboot from HTC page.
I'm one of the lucky ones who has had their I/O tab stuck in a boot loop on 3.1, and after trying the steps below, I am not getting it to work. I know I must be making a stupid mistake somewhere along the line, but essentially,
I downloaded the new image, boot, and recovery files into a directory on my hard drive;
I installed PDAnet;
I entered into fastboot on my GTab and plugged it into my PC;
I can tell that fastboot is now listed as a device (I suspect this means that the drivers are installed correctly and that it is recognizing a fastboot device);
Now when I try to run the fastboot commands suggested, I get 'fastboot' is not recognized as an internal or external command...
Stupid question, but I am supposed to run this command from cmd.exe, right? Any ideas what I am doing wrong so that the fastboot commands are not recognizable? I may need a dumbed down instruction set if there are steps I am missing somewhere...

Edit:
After trying just about everything, I have concluded there are two hurdles I still cannot pass. First, if I fastboot my device, and select the USB icon, my device is appearing in my windows device list. However, I cannot run any fastboot commands in cmd.exe window. Not sure why or what else is needed. Second, I successfully installed SDK and tried to enter recovery mode through ADB, but I cannot find the magic trick to have my device appear in ADB. ODINing back to stock did not make a difference. If I can get past either of these hurdles I am confident I can progress, so any suggestions are appreciated.
fastboot commands never seem to work for me. Always says waiting for device.

Which makes me wonder if I am doing something wrong. I can't even get fastbook command to be recognized. It's as if there is some fastboot software needed so that my pc knows what to do when I type fastboot. I hoped SDK was enough, took a stab with a fastboot.exe from htc I found on another forum, neither worked. How did you get your pc to look for your device from fastboot in the first place?

Hi .. I have the same problems before
I found out that the new ADB has moved the directory to "platform-tools"
This renders the fastboot useless "winapiadb.dll"(or something) file not found pop up window
I got that ridiculous bootloop issue right in the middle of the flight! thought I bought a $$$ junk lol
use the fastboot -w option to recover .. but it resets the whole tablet back to OE (original everything)
Hey guys,
So I have one of the Limited Edition Google IO Galaxy Tab 10.1's and I can't find a more updated thread than this. It seems this problem is isolated or mostly isolated to the Limited Edition tabs?
Anyways, I've read through the thread (as well as many other resources) and I just don't understand what I'm supposed to do to defeat the boot loop problem.
For me, pressing the Power and Volume up button (or Power and Volume down button) doesn't do a thing. The tablet does not respond at all. The only thing other than the boot loop is that I can get it into "upload mode" whatever that is.
This thread doesn't mention upload mode, so I don't know how to proceed. I can't seem to find anything in the manual about this sort of hard reset, nor can I find any information anywhere else.
Also, I've read this thread, and I do not have any familiarity with what the following software projects are: Odin, PDAnet, and APX Drivers. I also have not used the android SDK.
Also, in the third post chris eckman posted a link to some sort of Galaxy Tab drivers on samsung's site, which is now a broken link.
Anyways, while I'm a noob to the XDA community, I am a computer engineer, and I'm confident I won't have any trouble recovering this device. There's just so much conflicting information and alternatives methods that I'm not sure how to proceed.
It seems like a tutorial might exist out there that I have not yet found?

Anyways, I've read through the thread (as well as many other resources) and I just don't understand what I'm supposed to do to defeat the boot loop problem.
For me, pressing the Power and Volume up button (or Power and Volume down button) doesn't do a thing. The tablet does not respond at all. The only thing other than the boot loop is that I can get it into "upload mode" whatever that is.
This thread doesn't mention upload mode, so I don't know how to proceed. I can't seem to find anything in the manual about this sort of hard reset, nor can I find any information anywhere else.
Also, I've read this thread, and I do not have any familiarity with what the following software projects are: Odin, PDAnet, and APX Drivers. I also have not used the android SDK.
Also, in the third post chris eckman posted a link to some sort of Galaxy Tab drivers on samsung's site, which is now a broken link.
Anyways, while I'm a noob to the XDA community, I am a computer engineer, and I'm confident I won't have any trouble recovering this device. There's just so much conflicting information and alternatives methods that I'm not sure how to proceed.
It seems like a tutorial might exist out there that I have not yet found?

Ok, well if you are running a "stock" IO bootloader, then you should have fastboot and download modes accessible to you by using the volume down and power button combo.
Have you ever gotten to this menu before? If not, then you just aren't doing it right. Let go of the power button part of this combo once the samsung logo appears, and then you should see two icons appear. If you have an IO bootloader, then you are going to go into fastboot mode, and then use fastboot to get your recovery booted. Once you get CWM booted, you can flash a stock ROM, load up stock recovery and wipe this sucker back to factory, and then fastboot your CWM recovery and install Task650's latest rom and be bootloop free. Let me know if you need further help.
Alright, first things first. Yes, this tablet is 100% stock, and I've done one major Android update, but it was not the one that broke everyone's wireless.
----------
So going step by step:
you should have fastboot and download modes accessible to you by using the volume down and power button combo. Have you ever gotten to this menu before?
So, I did once get to what I believe was the "fastboot" menu. I had four options available to me, the first one was something like "repair boot process" which I selected, because I was having a boot problem. It did nothing, and now I cannot get back to that menu.
I did get to the USB upload screen once by accident, when I was trying to get back to the boot menu, but not knowing what to do at that point. I had to shut it off.
Let go of the power button part of this combo once the samsung logo appears, and then you should see two icons appear.
Which Samsung logo? If I press both the power button and volume up or down, I get nothing. Nothing happens. If I press the power button first and then two seconds later start holding down the volume button, then eventually I get the blue swirly samsung screen. At the end of that, the samsung logo is clear. But waiting a bit longer, after about 30 seconds of blank screen, a pulsing white Samsung logo comes up, and I've never known which samsung logo to stop holding the power button. I believe I've tried every combination imaginable, and none of them work.
If you have an IO bootloader Do you mean Google I/O Stock bootloader? If not, I have no idea what this is in reference to.
Once you get CWM booted No idea what that is.
you can flash a stock ROM Where do I get that?
-------------
My bootloop might be different from everyone else's. Everyone else says "shut off the device, and then turn it on with the volume down/up held down. The problem with mine is that it NEVER shuts off! So, I can only do about 2 tests per day, because the only way I can shut it off is to let the battery run dead.
Mine switches from boot loop, and if I force that off, by holding down the power button for 10-15 seconds, then it immediately boots back up into "going into upload mode, cause unknown" If I force that screen off, it boots into the boot loop, so I can never boot from a "powered off" mode, again, unless I let the battery run dead.
I've tried every button pressing boot sequence I can think of with no luck. Can't I just upload something to the device in "upload mode" ? I don't need any data off this device, I just want it to be reset back to day 1, so that I can turn it on and use it.
Thanks so much for your help. As you might imagine, this is a very frustrating problem.

Android NAND Rom Guide on RHOD phones for Noobs 12-15-12

I would like to give credit to everyone who has worked on the android roms, and other guides. I have taken some of the info for this guide from the WIKI
It seemed we were due for a friendly how to guide on how to load a NAND rom on a RHOD device. I decided to write a step by step guide to help people out. This guide does provide a very basic ADB setup, but it is just enough to get you up and running. If you want to do advanced things you should get the full ADB, and learn more about it.
This guide is written for a RHOD400, Android GBX0*+3.4.26 rom, and a Win7 pc, but should be almost identical for the rest of the RHOD family, other versions of Windows, and most other roms.
It is assumed that you have unlocked your phone for custom rom loading in the past at some point. This is not the same as unlocking the sim card. This is 100% required. Please read here and/or here, and/or here if you need help with unlocking your phone.
This guide assumes that you know what a command prompt is, how to load windows drivers for a device, and can open zip files. If these things are not within your skill sets I would recommend that you find someone who understands these things to assist you.
Things you need.
1. A RHOD phone.
2. A micro SD card that is at least 512mb in size.
Tip: I suggest a sd card that is less than 4gb in size. There tends to be less compatibility issues with non SDHC cards. SDHC cards usually work, but if you have trouble this is a good thing to change. The SD card does have to be less than 64gb in size as the phone can not read cards larger than 32gb.
3. A usb based micro sd card reader. A usb based card reader is need to be compatible with the HP format tool. Some built in ones are usb based others are not. If you have one, you can try it and see if it works. It is not recommended to use your phone's sd card reader for prep work.
4. A usb cable that is known to work. Test it in WM first. On rare occasion I have seen cables that did work with WM and not Android. If you have issues, this is also something good to swap out during trouble shooting.
5. A windows based pc. *DO NOT USE USB 3.0 PORTS* Many reports about have come in about them causing issues.
The procedure.
1. Back up anything you want to keep from your phone. Everything on the phone will be wiped during this process.
2. Put the micro sd card into your USB card reader and format with the HP format tool. It needs to be a full fat32 format. Windows format is known to have issues on occasion, and this step is a work around for that problem. It is not 100% required, but if you have trouble it is 100% required during trouble shooting.
3. While this is formatting you can download the recovery (recovery_cwr_6.0.1.3.img) ***It has been found that the 6.0.1.3 recovery does not make backups correctly, resulting in md5 errors. You may use it if you are not planning on using the backup feature, or the older one by acl works fine. You can rename it to use the included scripts if you wish.***, rom (GBX0*+3.4.26 Full) , the boot loader, the needed usb android drivers, and the adb files.Gapps is optional.
4. Make sure your battery is at least 50% charged. I recommend a 100% charge. A dead battery in the middle of flashing can brick your phone.
5. Copy the RHODIMG.NBH, rom (GBX0*+3.4.26 Full), and the gapps (optional) files to the sd card and put it in your phone with the phone turned off.
6. Press the hold down the volume down button while pressing the power button. This will bring up the tri colored screen. It will then automatically go to the white rom update screen.
7. Follow the directions (press the power button on the RHOD400) to start the update. This should take less than 1min.
Troubleshooting tip:
If the phone sits at loading 0%, and never moves after 10 min you may not have unlocked your phone or there is an issue with your RHODIMG file. Verify that you have unlocked your phone (you can try loading a WM custom rom), format the SD card, re-download the RHODIMG file, and try again. Also try another SD card and SD card reader.
8. If the phone reboots automatically, that is fine. Otherwise when the phone says Update Success you can pull the battery to shut it off.
9. Turn the phone back on. You should see a blue miniPooploader screen with a lot of white text scrolling for a moment. When it gets done, pull the battery to shut it off. Then replace the battery (it should still be off)
10. Connect the usb cable between the phone and the PC, and turn the phone on. The PC should see the device, and may or may not assign drivers to it.
11. Install the USB/fastboot driver for the phone. On Win 7 the phone showed initially as android device under other folder in the device manager. After the driver is installed it should be called My HTC.
12. Open the ADB Tools zip file, and put the platform-tools folder on c:\
13. Open a command prompt and go to c:\platform-tools\.
Once there type:
Code:
fastboot devices
You should get a response similar to this:
C:\platform-tools>fastboot devices
HT04TM300704 fastboot
If this is not working stop now and troubleshoot.
14. Now to wipe the phone in prep for loading (or reloading) the android rom.
There is a wipe.bat file I have included. You may run it, or you may type the following commands.
Code:
Fastboot erase recovery
Fastboot erase boot
Fastboot erase misc
Fastboot erase system
Fastboot erase userdata
Fastboot erase cache
15. Place the recovery (recovery_cwr_6.0.1.3.img) file into c:\platform-tools.
16. Now load the recovery image. If it is named recovery_cwr_6.0.1.3.img you may use the reload_recovery.bat or type:
Code:
fastboot flash recovery recovery_cwr_6.0.1.3.img
to load the recovery image then
Code:
fastboot boot recovery_cwr_6.0.1.3.img
to boot the recovery image.
17. Install the rom.
Using the volume keys highlight 'Install zip from sdcard' then press the call button to select it.
Highlight 'choose zip from sdcard' and press the call button to select it.
Highlight the rom file (GBX_3.4.26_Full.zip) and press the call button to select it.
Highlight yes and press the call button to select it.
The rom will now install. This will take a few minutes.
18. (optional) Install Gapps.
Using the volume keys highlight 'Install zip from sdcard' then press the call button to select it.
Highlight 'choose zip from sdcard' and press the call button to select it.
Highlight the gapps file (probably gapps-gb-20110828-signed.zip) and press the call button to select it.
Highlight yes and press the call button to select it.
Gapps will now install. This will take a few minutes.
19. Press the back arrow, and select reboot system now.
The phone should reboot into the Android rom now. It will take about 10min the first time. If you have waited more than 30 something has gone wrong. You should troubleshoot and try again.
At this point you have the basics all in place, and can start using your phone.
If you want to do basic ADB tasks (along the lines of installing apps remotely/side loading or pushing/pulling files) you will need to install the adb windows driver.
20. Press the thanks button if you liked this guide.
P.S.
If you have issues getting adb to work later, download and use USBDeview.exe to remove the HTC driver entries and then install pdanet for android to get the correct adb drivers installed.

Well if you have not listed all your trouble shooting steps, you will not get help from anyone. Our physic abilities are lacking these days.
Also posting specific questions in the thread about the rom you are trying to install will have a higher chance of getting useful feedback.

Well if you have done all necessary things, then your phone must not be compabtiable.
Maybe if you provided a list of your troubleshooting steps we might be of more help... Otherwise we have no choice, but to bow to your knowlage of having done all necessary things.

Thank you WizardKnight for replying me.
This is the steps i use to do.
1. I use RhodiumWUnlocker to unlock my rhod500 , to get any rom loaded with it
2. I copy RHODIMG.NBH, GBX_3.4.24_Full, recovery_cwr_6.0.1.3 all to my 4gb SDard
3. Vol- + PWR and phone turns to the tri color screen, then the phone started to load the image files
4. I press PWR butt to start the update, within a couple of seconds the phone update successfully
I press resest button for the phone to boot up to see if it will go to the fast boot screen.
But i was unlucky always the phone restart itself within some seconds.
This is my Prb

Sounds like you just need to flash CWM... the CWM recovery image doesn't go on your SD card, you flash that from your computer using the "fastboot flash" command...
You can also try "fastboot boot <recovery.img>" - w/o the < >. Remember, this is done on your computer. That's why you need the fastboot drivers...

You Mean This .
9. Turn the phone back on. You should see a blue miniPooploader screen with a lot of white text scrolling for a moment. When it gets done, pull the battery to shut it off. Then replace the battery (it should still be off)
My Phone doesn't bring this window

I have a rhod400. I have been messing with OMGB as my daily phone OS since July 2012 and just installed this one about a week ago.
I have two questions/issues
1) Every time I try to reboot, it freezes. When I try to power off, it sometimes freezes, but usually reboots.
2) I can't seem to make persistent changes to the hosts file. After every reboot, it's set to the same old generic "127.0.0.1 localhost"
During boot, does the OS unpack a .img or something with the hosts file packed inside it? If so, where is it?
Thanks, guys. Other than these 2 issues, this flavor of android for rhodium is pretty solid. i like it.

Please put rom specific questions in that rom's thread.
If you are running a newer than.27 kernel the reboot and power off functions do not work properly in any rom.
I believe that the host file is overwritten by the ram disk/boot.img on boot every time. Any changes will not stick.
There is a chance these issues may be fixed on the next release of GBX, but no promises.

[Q] I have bricked my Dragon Touch A1X tablet. How do I get it up and running again?

I purchased a Dragon Touch A1X 10.1" in hope of rooting and learning about flashing roms. I think I didn't realize how out of my depth that I am in.
Right now when I power on my device it shows the dragon touch logo for a few moments and then goes straight to an animated Android waving at me. It does nothing else. I let it sit over hours and it still waves at me. If I boot into the recovery I can wipe and format to factory settings, but that does not make it work again.
I did do some searching and reading. I went to tabletexpress to get the img and the tool to get my tablet up and running again. When I run LiveSuit or PhoenixUSB and I choose the proper img file the program never changes it's red light to a green light, which it is supposed to do.
I really did not want to post here. I wanted to figure it out myself. But after several days of no progress I do not know what else to do.
Any suggestions?
[EDIT] I didn't mention that I can boot to the Android system recovery. The options provided are (1) reboot system (2) apple update from ADB (3) wipe data/factory reset (4) wipe cache partition (5) apply update from internal storage (6) apply update from external storage (7) apply update from cache-no command. I hope this helps someone understand better where I am at.

How did you get yours in Recovery Mode? Please tell me! I did the same thing you did in your post!
I am sorry I didn't reply sooner. I don't check my email often enough. While the power is off, hold down the volume down button and then turn on the tablet while still holding down the volume down button. The tablet will boot into the recovery mode. From there you can wipe it. I did that and the tablet still didn't boot up. I contacted Dragon Touch they sent me to there support site. Google "tablet express support". It is the top link. Download the firmware from there. Then I:
1) turn the tablet off then
2) when the tablet is off press and hold down either volume button
3) while holding the button down plug the tablet to you computer via USB
4)while the tablet is plugged in AND you are still holding down the volume button press and release the power button 3 times
This puts the tablet in a firmware update mode. I don't know what else to call it. Then their site says to use the Phoenix USB program to restore but that didn't work for me. Livesuite did work for me though, and it took me way longer than I care to admit to find it. I didn't know to go looking for it. Google "livesuite" and it is the top result. Run Livesuite while the tablet is still connected and point the program to where you downloaded the firmware. From there it was smooth sailing for me.
I would imagine that you have fixed your problem by now or moved on, but I still wanted to respond in case someone else comes along looking for this info. I hope that this helps somone.
PS: I can't post links so that is why I made google suggestions to help you find the links I used.

kingo root app works to root.

soft bricked my phone... desperate for help..

alright guys, so here's the story. just yesterday i bought a brand new lg v10, got it home and the first thing i did was root the device and used ADB to load TWRP following the instructions here on SDA to a T for the ROOT/RECOVERY setup. and it worked. all was fine and dandy, the first time i booted into TWRP via ADB after root i got in, flashed a debloated ROM + xposed and again, everything went fine.. loaded into the OS of the new ROM, went through setup, turned on USB debugging, clicked always allow this computer, installed xposed app yadayadayada. I then, using ADB again, loaded into TWRP. i created a backup there just in case something went wrong with the changes i was about to make and once the backup was complete i loaded back in to the OS. at this point i thought i had done everything right and was confident that if i made system changes that didn't work out i could just flash the phone with TWRP from the backup i made. right? WRONG! ...apparently... so anyways, i made my first change, which was to use a NONROOT app called texdroider or whatever to change my DPI (as i have done with a couple phones previously without much issue) but i didn't take into account that stupid second screen... making the DPI changes system wide, as i'm sure those of you that know this phone are aware, causes the systemUI to crash with an error.. making the OS unusable.. so i tried to load into TWRP by holding the volume down and power button.. but instead it just booted me to the factory recovery.. not TWRP... the phone is unusable within the OS, i can't get the phone to connect to adb to boot into twrp as i had previously, i can't seem to get the phone into download mode, and i can't boot to TWRP and the OS is junk at this point.. but it DOES say on the "LG" screen that the bootloader is unlocked so i'm really hoping i'm not completely out of luck.. but i am not sure what to do at this point. does anyone here know of anything i can try to get into a custom recovery at this point? if i could get into TWRP my SD card in the phone has a backup, the original image, not to mention i could pull the SD card and add anything i need via my pc and then boot back to twrp etc etc and i would have no issue fixing the phone... i really don't understand what i did wrong or why i can't boot to my custom recovery but i'm at a loss.. i'm just looking for a way to force the phone into a custom recovery... or restore the original factory image.. if you have any advice at all i would really appreciate it.
Thanks for reading
**UPDATE** this may or may not make things much easier... but I got download mode working!! so at least there's that, still no custom recovery and i'm currently looking for a KDZ or TOT file to flash via lg flash tool... hopefully that makes things easier..
When you say you got to the factory recovery, what was that, an Android on its side or something asking you to factory reset your device? If it was the factory reset screen, if you select yes and then yes, it will take you to TWRP if you have it installed. If you don't it will factory reset your device.

To boot into recovery from power off, you hold volume down & power. When you see the LG logo release and press power while continuing to hold volume down. Then as said above, it come up as a factory reset, select yes each time, and it should boot into twrp, providing you installed it correctly.

it was a screen asking me to do a factory reset, i click yes, it asks to confirm, i click yes again and then it "successfully" factory resets my phone... it shows the android factory reset symbol that its resetting, then says that its "optimizing apps" and goes through that whole process.. but when it finally loads the "welcome" screen (so i know for a fact that some sort reset has taken place) i get the same "systemui has crashed" error and the OS is unusable and won't connect to my computer.. idk why i can't access TWRP.. i booted to it 3 times before this happened, though never by the hardware buttons on the phone.. everytime i booted to TWRP i had used ADB to boot to TWRP.. what makes me the most sad is that i have a nandroid backup on my SD card... but i can't flash it without recovery.. which i can't install on the phone without getting into the OS..
is there any way to install TWRP or even boot to a temporary TWRP so that i can do so? if i can flash my nandroid i'm saved.. if i can get into a custom recovery i'm saved.. if i can find a .kdz file to flash, i'm saved... if i can get my phone to be recognized by my computer/adb i'm saved.... there simply has to be a way to unbrick this phone...

well i seem to have somehow NOT installed TWRP correctly because it just proceeds to factory reset my phone.. which for some odd reason doesn't reset the DPI... leaving me stranded... is there any way to get ADB to see my device in its present state? my computer makes the device recognition noise when i enter download mode and i can see it in device manager but not my computer or ADB
I've had this phone just over 2 months but I'm not positive, is download mode the same as the bootloader on this device? If so, fastboot commands should work, and you can flash TWRP again, or do 'fastboot boot TWRP_filename' and it will boot TWRP temporarily.
Oh, and the factory reset just wipes your data, but otherwise doesn't restore your system to factory state. That's why your dpi change remained.

dude.. then what good is a factory reset?!? like seriously... and yeah, i tried that but i can't get adb to connect in download mode.. the device doesn't show up when I type "adb devices" like it did when i first rooted it. ... and i thought i followed the instructions exactly as it was laid out from this link.
http://forum.xda-developers.com/tmobile-lg-v10/general/guide-how-to-root-lg-v10-easy-t3274699
i think somewhere in there i must have missed something and ended up only booting into twrp temporarily.. which is certainly possible since i never boot to twrp during that initial process from the hardware keys or soft keys.. always through adb.. the phone was already plugged in.. typing the command was a couple keys away..
is there anyway to get TWRP on to the phone now? or am i screwed :'(
Well, it is a factory restore for the average user, because the average person isn't modifying their system. But no, I'm sure you're not screwed. If you're in the bootloader you can't use adb, you're already past that step, so you can skip to the fastboot part. What happens when you type fastboot devices? If the phone shows up then you can either fastboot flash or boot TWRP..

from what screen should i be attempting this? hold volume up with phone off and plug in to computer to enter download mode? should i try it at the factory reset screen (volume down plus power)? those are the only two screens i seem to have access to.. in download mode my pc/adb just doesn't recognize the phone.. it doesn't show up as a proper device like it did before this whole thing and in that factory reset mode i get nothing.. the download mode seems like its built for LG and runs from different drivers because in device manager it shows up with an error code that it couldn't start the device (this was not the case when i was using adb to unlock the bootloader and then using the bootloader to boot to TWRP..) what am i missing?
and hey, thank you so very much for taking time out of your day to help me. I really do appreciate it.

No problem buddy, and sorry for the confusion. You want to be on the bootloader screen, so here is what you can do: turn the phone off(or remove the battery if you have to, and put it back in), plug the usb cable into the computer only(not phone), hold volume down on phone, plug the usb cable into the phone. That should get you into the bootloader, and then you should be able to fastboot flash or fastboot boot TWRP.
Waiting for a resolution to this thread!
I'm pulling for you from the cheering section. (otherwise known as afraid to do it myself section!)
I'm pretty sure others have come through this exact situation unharmed (I've pretty much read every thread here.) so it's only a matter of time before you get this figured out.
Here's hoping it's sooner than later.
Sorry I can't offer more besides encouragement!

@ngoblirsch Along with the information provided in these suggestions and what you have said, you need to reinstall your LG/fastboot drivers on your PC while in fastboot mode

OH DEAR GOD THANK YOU!!!!
I spent all damn day yesterday trying to figure out how to get to the bootloader on this phone.. everything i read online said to hold volume down PLUS power while plugging it in and it was NOT working lmao. dude, thank you so much. after i read that comment here it took me about 30 seconds to connect to adb and boot to TWRP. This thread can be listed as RESOLVED!
Thanks again!! can't wait to start tweaking this awesome phone!

Well I appreciate the encouragement, it sure seems to have helped! Issue has been resolved. ended up that i just didn't know the hardware key combination to get to the bootloader/fastboot mode without being already connected to adb. nothing that i could find online said to hold volume down while plugging it in to a computer. as soon as i was able to do so i connected to adb and it was a breeze from there; I am now back with an OS AND a customer recovery properly installed on the device!! I will be hanging around these forums for as long as i have this phone so i'm sure i'll bump into you guys! absolutely love the community here on XDA, you guys are freaking awesome!!
