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.
Good Afternoon All,
I'm a complete gtab noob for starters. Anyway, I am attempting to install ClockworkMod v8 following the directions here: http://forum.xda-developers.com/showthread.php?t=865245 but cannot seem to get it to install. I have transferred the files with no problem but after powering off, then "Up Volume/Power On", the screen just remains with the "3 Birds" and -Recovery Key Detected- and -Booting recovery kernel image- messages appearing.
I let it sit for a while the first time, then powered off. I can then power on and get the stock screens with no problem and the tablet seems to work fine. Then I power off and use the "Volume Up/Power On" routine and I just end up getting stuck again.
I have searched around a bit on these terrific forums but just can't seem to find the solution that fits this exact problem.
Any help would be greatly appreciated.
Thanks in advance........

I see quite a few views but unfortunately no replies. Can I safely just delete the files from the root directory of the gtab and place them on an external sdcard and try again or will deleting the files from the root cause another problem?
Thanks to all who have read about my issue. Hopefully we can come up with a solution.

Nearly the same here but once mine shows "recovery key detected", it reboots again and starts normally.
I can get it to boot normally by powering it down and powering it back up. I just can't get ClockworkMod to install no matter how many times I do the "Volume Up + Power Button" routine.
As a result, I am limited as to what I can do with the gtab.....
im having the same problem :/ i really wish i knew why too...i tried it so many times but it gets stuck at booting recovery kernel image
Install clockword
Same problem here it's install,but after the second reboot I can't the clockword menu it's reboot normally
You guys may have 1.2 bootloader. I do not think CWM v8 works with that bootloader. Look around for how to fix your recovery.
I just received my g tablet today (w/bootloader 1.2) and I am having the same problem as the OP. After installing CWM it will boot up normally, but when I try to hold the volume up and power keys to go into recovery it just stalls at the initial 3 birds screen.
I'm a noob and not sure what my options are to get a custom MOD on this thing. Any help appreciated.
Good god. Every thread these days have been talking about 1.1 and 1.2 compatibility. If you have 1.1 use cwm v8. If you have 1.2 use cmw 3028. In addition read second post by moi in the following thread.
http://forum.xda-developers.com/showthread.php?t=1120387
At this point you need to nvflash the appropriate cmw. Go to the following thread.
http://forum.xda-developers.com/showthread.php?t=1030042
I have exactly the same problem it sticks at the same place
Guys, you are using the wrong CWM version. Visit my website and use the right version. V8 only works with 1.1 bootloader. You have 1.2. In my website, look at option C. It shows you how to nvflash the right CWM file.

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?

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:

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.

Hey guys.....
This is pretty much my first thread . I have got a Chinese android tablet called HSG MIDX5A Telechips Tcc 8902 (a.k.a. Herotab RK7, Pandawill G11 1st model) with ARM1176J2 chip.
What I did yesterday is that I tried to get it into recovery mode and then somebody on IRC assisted me to flash the tablet with the recovery image using fastboot and then I got the recovery mode <3e> working but I was not able to navigate through the recovery menu using the home, back and menu buttons. However I do not have any Vloume up /down keys with this tablet .
BUT this is not my problem now. After I failed to navigate through the recovery menu I decided to flash a new lk.rom file using FWDN V7 2.13 and that went fine but as you guys know I need to flash the tcc8902_mtd.img after that. Here is the problem I want to get into the FWDN mode to flash the tcc8902_mtd.img but I`ve been trying since yesterday and I was not able to go into FWDN mode. My tablet is not booting too normally. I`ve tried to make the splash screen "I love you " to still there but no hope. I`ve tried the home+power button and also power+touch the center of the screen also did not work too. Whenever I release my finger out of the power button it just turn off.
So please what do you guys suggest ???
Alternatve method ?
I heard about USB Host boot mode or is it no longer needed even in my case ?
What about this ?
I am really sure that I flashed the right rom.
Again I am really struggling on how can I put the tablet in FWDN mode, however I tried the combination you just mentioned and it did not work for me . Yeah something happened to me yesterday that I tried to push the middle of the screen but firmly and really hard at the same time I hold the power button and finally the splash screen"I love you" freezed as it should be but I was not able to get it detected by FWDN V7 2.13 ? Am I doing something wrong ?Should I switch to windows xp 32 bit ? I am using windows 7 64 bit which I had to hack the drivers in order to get the tablet detected at the first beginning before I flashed the lk.rom file so please help
Hello and thank you for anyone bothering to read this.
I got a CAT S50 and was experiencing a bit of instability lately.
I've run LTE_S0201121.0_S50_0.023.00 without a hitch for a while, then it decided to crash several applications, from google play to any other app open.
That's when I decided to do a factory reset and see if it would help. Performed the rest without a hitch, but the errors kept coming back. At one point, the screen went black. I knew the phone was on because the backlit was working. I hard-reseted it (hold the power button for 30 seconds or more) and rebooted. The phone froze on the CAT splash logo screen and that's when I hard-reset it again. But when I tried to turn it on, the phone simply refused to work. No vibrate, sounds or anything. It's dead.
When I plug it on the computer's USB, the PC makes a sound as if it detected the device, but when I go to the device manager, I get this QHSUSB_BULK with the yellow exclamation mark
I want to know if it is possible to unbrick this phone and if so, if there is a tutorial or if someone can direct me to the correct procedure. I looked everywhere for the ftf file for this phone to attempt this with flashtool, but I simply can't find it.
ANY help of any form is greatly appreciated.
Sadly I had the same thing happen to me, just a black screen. It decided to delete recovery mode or I just cant get to it.
Power Off the Phone,
While pressing Press Vol Down + Cam Button insert a Powersource -- hold down Vol Down + Cam
Recoverymenu should start
Then flash the original rom via ADB Sideload or SD Card.
btw. i have flashed the LTE_S0201121.0_S50_0.023.00 but i want test older ROMs!
can anyone link or upload an older ROM ?
Guy i have the same issue, can you please help me
I got the same problem I search lots place but still nothing then normal update rom anyone can help?
