Im having trouble booting to recovery - LG K7 Questions & Answers

Hi,
I just flashed twrp following the instrustions from a thread on here at the following link.
https://forum.xda-developers.com/lg-k7/how-to/t-mobile-lg-k7-thread-t3481844
Now when I try to boot into recovery by holding the buttons together to install su, it just boots up how it normally would.
Ive tried every possible combination of buttons to hold, I even tried booting to recovery from the command line by typing
adb reboot recovery
which it does reboot but to a screen with the android laying down opened with an explanation mark with in a triangle and underneath the total image it says no command Does anyone have any ideas of what im doing wrong or suggestions
any help would be much appreciated thank you!

I've had the same problem, except If I input adb reboot recovery I actually get into the recovery. Have you tried flashing with the TWRP app?
EDIT: I have your solution. Reflash TWRP 3.1.0.0 using the TWRP app, turn off your phone. Holding Volume Down, hold down the Power button until you see the LG screen, then press Power again. Select Yes on the screen that appears, then Yes again. You will be taken to TWRP.

Hi,
Thanks for the response, however I did actually figure it out later the night that I posted this. I just ended up typing adb help and read through the commands and after a little playing around did adb reboot recovery, but I would get the read explanation mark. So then I rebooted into the bootloader typed fastboot boot twrp-image-3.image which got me in then I installed the SuperSU zip then from the bootloader I reflashed twrp rebooted finished Installing SuperSU then did adb reboot recovery and it brought twrp right up. So that took care of the red explanation mark. Though I still cant bring up recovery by using the button combination method, but adb reboot recovery works just fine. As far as I can tell I am rooted, however this is my first time doing this so im not too sure what all I can do.

Nesesito ayuda con mi lg_k330 no entra a modo descargar le he hecho de todo el telefono me detine las aplicaciones y nesesito hacerle la rom alguien me ayudaria con este problema ya que lo reseteo de fabrica y aun continua deteniendo la aplicaciones.

[Q] LG Vortex stuck at boot screen, can anyone help to get into recovery mode?

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.

How to unlock Huawei MediaPad 7 Lite locked after "too many patterns attemts"

How to unlock Huawei MediaPad 7 Lite locked after "too many patterns attemts"
One of my friends have a Huawei MediaPad 7 Lite S7-931u. Recently his son tried few pattern attempts & It began to ask google account to unlock saying "Too many pattern attempts"
But it is not possible as it doesn't connect to Wifi or mobile network in this status!
Its ICS unrooted one & he doesn't know whether debugging enabled or not & no recoveries installed..
We both tied to upgrade it with official update from Huawei(by copying "dload" to SDcard). But instead of upgrading it restarts normally to the above screen asking to sign in to google account to unlock.
so the tablet became totally useless.
Is there a way to Hardreset/Install a new ROM or any other method to make this work?

what i have learned for updating is, to extract the update.app and unlmt.cfg to your sd card root.
then while the mediapad 7 lite turned off, simultaneously press power key and volume down, once you see the bootscreen huawei mediapad 7 lite continue to press volume down key, til you see the android icon, release the volume key down and while the gear is moving press one more time the volume down key. it will reboot for about 2 to 5 minutes and it will be upgraded or reflashed, because there is no update from their website, the same update ICS 4.0.3. to factory reset it, you can press power and volume down key simultaneously and once you feel it vibrates, continue pressing the volume up key. your media pad 7 lite will be factory reset again.
good luck and i hope this helps. you
First of all: while device is off press "power" and "left" together... after vibration, release "power", but keep pressing "left".
If this was done right, the "fastboot" loader comes up.
When you got to this point, you could be hleped further.

mediapad 7 lite force upgrade
I had the same problem with my tab and i have solved it.
jhha you are doing the right method just missing out a few steps maybe
Click to expand...

Now try these steps-
download the device software from the huawei website (go to huaweidevice.com ==>select mediapad 7 lite from smartphones list ==>click on software tab ) according to your device
Extract the files to your computer and read the manual given in the downloaded zip file "CAREFULLY"
Keep in find that the SD card must hav atleast 2Gb free space after the dload files have been put into it
Make sure your sd card's format is FAT (you can do that by formatting the sd card on your pc and changing the format there)
Don't worry about the optional files(as they are optional)
Just read the manual and follow the above steps and you are done
Cant reset

Hello,
I tried it and now the android icon appears but it only restart after that,
I've fixed my problem this way:
1. turn off tablet
2. press and hold power and left key simultaneously
3. once you see the logo of huawei, release left key and immediately press right key continously till you see the android icon and the gear moving around
4. continue pressing volume up key until it reboots
5. once it reboots, you will notice that it will ask for your email,so it is on factory default settings now
Please ignore post. Sorry for the mess.

Cannot boot to recovery or fastboot-rooted LG V30+

Hi all. I just recently unlocked the bootloader and rooted my LG V30+ following the WTF guide with no issues. However, I installed a "Hide navigation bar" module in Magisk and now the screen is in accessible and I can only reboot the phone. Since I have TWRP installed, I cannot boot into bootloader holding down the volume down and power buttons. Any suggestions? I cannot use adb becuase it says that the device is unauthorized since I cannot allow permisions on my screen ( cant see anything on screen atm).

You can boot to TWRP with hardware button dance.
8 sec Power + Vol-, and when it shuts off, release both, immediatly press both again (at the same time), and as soon as the LG V30 logo appears, release power and press/hold it again.
Should get you to the factory reset menu, confirm twice with "yes" (navigate via vol/power buttons), and TWRP should boot fine.
Might take a few tries to get the right timing for that

For that, remember the annoying bootloader unlock warning is part of the boot sequence.
Or do a Master Reset and start over.

Ignore bootloader unlock warning. It's just part of the boot sequence. Maybe it's considered the "logo". Don't let it freak you out.

I must have done this button dance 25 times now, it just goes between unlocked boot warning screen and LG SlimQ screen, over & over again. Still no luck.

Suggestion... Why not boot to TWRP with fastboot commands like in the WTF instructions? Then reboot to TWRP from within TWRP (reboot to recovery, from Recovery) to make sure you are then on your phone TWRP and not your PC TWRP.
Then after you root, use the recommended power menu app to never have to worry about it again.
If you already have root, then just go install that right now.
ADVANCED POWER MENU (root needed)

The person who started this thread couldn't do that because they installed something which messed up their screen. They couldn't see the Advanced Power Menu, nor see ADB/fastboot. So they HAD to use the hardware button dance...
Really no one else ever has to do that, except T-Mobile H932 users who don't have fastboot flash commands.
Hi Chazz, been unlocked and rooted with TWRP installed for months now. Wanted to just refresh us998 H, since something in Anxious mod may have been causing some issues. Wiped cache & dal, flashed the zip, flashed magisk 18.1, then rebooted to system. Magisk showing as not installed. Wanted to get back to recovery & reflash magisk....except now I can't for the life of me get back in there. New PC build here, nothing set up yet to be able to do fastboot stuff. Dang this is frustrating.

In Oreo, did you enable USB debugging and then allow ADB from this PC? You have to install ABD drivers, LG drivers, fastboot drivers, and connect via good USB-C cable. If so go into ADB folder, hold-shift and right click to 'open command prompt here', and type "adb devices". If the PC recognizes your phone then it should say "adb xxxxxxxx authorized". Then type "adb reboot recovery" and it should boot into TWRP. If not then repeat everything and type "adb reboot bootloader" to go into fastboot or bootloader mode. In this mode you can type "fastboot flash recovery twrp.img" where the TWRP-xxx-xxxx.img has to be renamed into TWRP.img before hand (else you have to type the full TWRP file name. The TWRP file has to be in the same directory as the adb folder
I'm good turns out I ended up using my old PC, was able to adb recovery mode, installed 19.2 magisk over 18.1, which then showed up as being installed on the phone and root working. Guess I'll be keeping my old puter around for a while...lol

So, It doesn't have to being open bootloader if I want to flash stock rom? Bc my bl is locked and I cant access it.
Bro you can't flash twrp without a open bootloader only the international models of the galaxy 10 have unlocked bootloader next time you buy an expensive phone and want to modify it research it first to see if it's modifiable

You can flash stock rom threw Odin in download Mode with a locked bootloader to get your phone to function again

Okay, I flashed the stock rom. Now the phone doesn't boot into download mode, but also I think it stucked at samsung logo. I cant boot into recovery, download mode neither. The only thing what I can do is power+vol down. But after this, the phone restarts and stucks at samsung logo again...

Hey, I'm having the exact same problem with my Galaxy A50, did you manage to solve the issue?
Then great job, you hard bricked one of the most expensive phones on the market... You should really do a research or at least a Nandroid backup before modifying your phone. This is a lesson for all of those who just flash and don't care. No hate bro, but next time while flashing, be catefull!!!!

Yes, I solved the problem but I dont know if it's good for A50 too.
So, you should try to boot into download mode. If you have the same problem, your phone boots very fast. You have to be faster. Hold power button and volume down, at the same time when connect your phone to pc.
After this, you will able to install (flash) the original rom from sammobile or etc.

Boa noite.
O meu S10 estava com a mesma mensagem de erro.
Consegui conectando e usando o ODIN com a Rom Original ZTO sem operadora.
Aqui no Brasil Originalmente uso com a operadora VIVO usando a Rom da VIVO não funcionou continua com erro, baixei a ROM ZTO que é de nenhuma operadora e deu Certo, tente com outra ROM que acho que vai funcionar.
Boa Sorte.

This happens on Galaxy A51 (Exynos model A515F/DSN ) anyone have solution for this ?
If USB cable is plugged in (unplug it).
1. Press Volume Down and Power button, until the phone restarts.
2. Quickly plug back the USB cable and Hold Volume UP and then Press Volume UP again (OEM is now off and the Phone will reboot)
3. Quickly press Volume UP & Down on the same time again *don't remove USB cable*, until download mode comes up.
4. This time only press Volume UP.
Now you can install you roms.

This worked for my on my a50 after a few tries. I couldn't get it to work at first, but I got the most recent version of Odin and then it worked without issues.

I managed to solve it!
simple!
hold down and power for it to restart, at the exact moment when it restarts, you press the two volumes, up and down, and connect the usb cable right after, before turning on, then a menu appears where you can hold up for 7 seconds and unlock the bootload
good god what a ****show of replies. Not once did anyone address the problem, just 1 idiot after another talking about how "expensive" the phone is.
My rooted s10 exynos does this also "error verifying vbmeta image" when it says "DOWNLOADING" instead of going to my latest twrp when installing it in Odin in the AP slow along with vbmeta.tar in the CP slot.
I wish we could remove all these idiots replies about how expensive they think the s10 is and just have the OP question and me saying I have the same problem and then me replying here when I find a fix.

Huawei P30 Lite Bricked?

The device I'm working with is:
Huawei P30 Lite MAR-LX1A (LIVE DEMO)
9.1.0.220D (C891E4R2P1)
So trying to remove the demo software using SigmaKey, I did software testpoint using UPDATE.app from 9.1.0.317 (C431E5R2P3) being the closest version I could find as I could not find the exact firmware matching C891.
After this I was able to connect as port Huawei USB COM 1.0, which I thought was already bricked as I couldn't charge or power on the phone. I then tried to write another firmware which I thought would be similar to the original being 9.0.1.161D (C891E2R2P1).
Now since then the phone powers on and gets stuck on Huawei Logo, and the only mode I can get to is Fastboot&Rescue. I cannot go into upgrade mode, it will just get stuck on logo screen. And now the device is detected as "^ Android Sooner Single ADB Interface …”.
Is there any way to save the phone from only the fastboot screen?
Thanks!
I beleive this one is pretty similar if not the same than MAR-LX3A or MAR-LX22A
this device don't have just a recovery partition it has 2, you have recovery_ramdisk and erecovery_ramdisk
if you still have the erecovery partition working you should be able to unbrick the phone. I happened to go trough the same situation.
to boot from each you need to do pretty similar steps
Recovery: hold "volume up" + Power button as soon as the huawei splash screen withe the logo release both keys.
eRecovery: hold "volume up" + Power button, but keep holding those through the splash screen after the splash keep pressing them for a little longer until the eRecovery screen shows up, it comes with basic wifi connectivity so you can download the stock ROM and rescue your phone.
make sure to disconnect the charging cable when doing so, and better if you turn off the phone completly and try if from complete shutdown.
that trick is not clarified almost anywhere in the net, it took a wihle for me to findout why sometimes it would boot to recovery and sometimes to erecovery..
it seems like after the splash screen the phone still have a choise for booting, similar to installing a BIOS based os in a EUFI firmware mb.
I dont think there are other roms in this device working at this point. all you can do is patch a magisk image and flash it to the recovery_ramdisk partition, that will get you root access, but custom ROM is another story
If I happen to get one, I will let you know.
Boa noite, boa tarde ou bom dia. Meu amigo tem um MAR-LX3A nessa situação e não estou encontrando solução. Por acaso você tem a rom e os drivers dele para me ajudar? Muito obrigado antecipadamente.
