US996 Unlocked, stock rom. I was in XDA Forums and saw there were app updates, one being Play Store. I updated. When I tried to get into Play Store, the message "this version of play store is incompatible with your device, go to settings and disable app update (or something like that). I tried but the app was not listed in settings. I tried to reboot and now the phone bootloops. All I can get is the warning that the software cannot be checked for corruption and then a quick display of the LG logo, then screen off, and then LG logo again and then warning screen, etc. If I try to reboot into recovery I get the Factory data reset screens and I answer both "yes" and the phone goes into adb mode.. From adb mode I can fastboot reboot, which puts me back into the above loop, or fastboot bootloader, which merely returns me to the adb screen. What can I do now?
Maybe try relocking the bootloader. I am pretty sure (someone correct me if I am wrong) that that pop-up of the "cannot check for corruption" usually only shows when the bootloader is unlocked.

Try entering
Code:
fastboot oem device-info
into Fastboot on your computer to see if it says it is unlocked when in fastboot mode.

I get "FAILED (remote: unknown command)"
Do you have fastboot installed on your computer? (Something you would have had to have intentionally installed) If not google Minimal Fastboot /ADB and install it, enter the supposed ADB screen you are talking about and see if it makes contact with your phone.

I have the fastboot on the PC that I used to unlock the bootloader.. I enter fastboot on the PC via the administrative command prompt. With the phone in the fastboot mode, I type "fastboot devices" on the PC and get a proper response (LGUS996ab**** fastboot). If I enter ""fastboot reboot" I get the bootloop. If I enter "fastboot bootloader" I wind up in Fastboot Mode on the phone again. I was hoping there was a "fastboot recovery" command but there doesn't seem to be. I don't know what to do next. I am not all that familiar with what can be done from fastboot. My only experience with it was when I unlocked the phone. I am desperate!
Okay, so if you do not have TWRP installed on your phone, then I don't know if you can save your data. You can try to
Code:
fastboot erase cache
and see if it helps, or if not and just reset the device fastboot oem lock I think. Maybe ask around in the unlocking help threads or perhaps someone with more knowledge will chime in. If none of this works, then there are some instructions on how to get your phone back to stock in the News and Guides section.
EDIT: Maybe try the power+volume down. It may work? I have tried it and never got it to successfully work. But you can try it.

Thanks for your help. I DO have TWRP installed and have used it often for backups. But now the only way I know to TRY to get to it is by the power/vol down until LG logo, then release/repress power button sequence but this just gets me into fastboot mode. II have some recent backups saved on my micro SD card - is there any way to flash one of them through fastboot if I load one onto the PC?
Yeah. My bad. Okay, so how I get into TWRP is through the EasyRecowvery.
Go ahead and download it from Git-Hub (1.3b3).
Now extract it and run the cmd program. Enter 5. which is extras and stuff and then enter 5 again in the sub menu which will let you boot into recovery. When you are in recovery, and plugged into your computer, you should be able to either flash or drag and drop like a flash drive on the the phone. Hope that helps a little bit.

Since you are only rebooting into recovery and not flashing anything it might. If not, it will just fail and not harm anything. Last thing to try is the
Code:
adb reboot recovery
which is the only thing I can think of and I think you already tried it. Otherwise you will need to just go stock.

How do you guys boot to fastboot if you have turned your phone off? I mean the actual fastboot ("black Huawei logo") not the recovery and not the pink bootloader. I can get to it if I reboot my phone if I press reboot and then bootloader, but is it possible without it?
Seems like there is no other way. Right now I can start it in fastboot mode with "adb reboot bootloader" and the custom ROM I have on right now. If anyone wants details, post here.
-e-
Weird discovery I made. While trying to flashall it says the device is "swordfish"... If I flash system.img separately it says "no partition table exists". Anyone has used fastboot before?
Nice. With the new Android version, the product shows MSM7630_SURF. It now properly boots to fastboot without going to charging too, so thats an update.

I tried fastboot, but I just get a black screen with huawei logo. No any function, no adb connection, no menu entries or anything and no buttons work. And I can exit only by remove battery. Is this right?

There's an external tool called fastboot which handles that. There you can reboot or even continue the boot.
Fastboot is broken as far as I know, no partition table exists.
Sent from my U8800
You mean the fastboot from adb tools which can used from command line? This cannot work because there isn' t adb connection on bootloader mode.
Or is another tool which can be flashed or something to device?

I think you are confusing pink screen with fastboot/bootloader. The fastboot is the node where it stays in the Huawei logo.
Sent from my U8800
No, I know the difference. I get this screen, but nothing else. On my previous device, fastboot has some functions included flash rom, reboot and some else that I don't remember. I also could from adb to use fastboot command.
On X5 I just get this screen.
Maybe they disabled that in B522 too, I am not sure. It was bugged anyway. I only tested it on B138 and B518.
Yes, I have 522 and I thought this too. I've tried on B138 1-2 times and was the same huawei logo screen only too. I didn' t tested it more because I thought that just this mode is disabled and used pink mode only. In B138 sould appear something else on screen, or only commands from adb work?
This is the method tried on H815T model. But I think this should work with also other H815 models (other devices cannot say). Thanks to @autoprime, @thecubed and @Unjustified Dev for this.
Disclaimer: I am not responsible if your device gets into any more trouble for this.
Steps:
1. Download & clean install LG Drivers in your pc if u don't have it already.
2. Go into download mode by presing down the UP button and connecting the usb cable to the pc.
3. Go into LG ROOT folder. see this link to download: http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
4. Double click on ports.bat to know your COM port. Let's say it's COM4.
5. Open a windows command promt by Shift+Rt Click into the Lg Root folder.
6. Now send these commands:
Code:
Send_Command.exe \\.\COM4
It will reply
Code:
SPECIAL COMMAND : ENTER , LEAVE
#
7. Now command type
Code:
id
It should reply
Code:
uid=(0)root gid=(0)root
#
8. Now type
Code:
dd if=/dev/zero bs=8192 seek=35840 count=5120 of=/dev/block/mmcblk0
It will reply
Code:
#
9. Now pull out your battery, put it back in, go into HARD RESET mode by pressing down DOWN BUTTON+POWER BUTTON together and when the LG logo apprears, release the power button for a second and press it back again.
10. Now in HARD RESET, it will ask you whether you want to reset everything or not. Select "No" and it will take you to fastboot mode.
Special note:
1. @autoprime told me to factory reset everything before starting this whole process. I did as my bootloader was locked. Don't know how it affects in unlocked bootloader.
2. How to get out of fastboot normally: I don't know it quitely. My bootloader was locked, so neither I could flash any system file through fastboot, nor "fastboot reboot" or "fastboot reboot bootloader" worked for me. @autoprime told me to get out of fastboot, manually go into download mode, then pull out your battery and put back in. Actually you can't get out of the fastboot that way until you flash a KDZ.
Thank u. Reply in the comments if fastboot could help you any.

Hi,
Thank you very much for this Guide. Unfortunately, having tried to unbrick my device (H815) previously by hard resetting and not having access to Android to re-activate ADB, the Shell (Send_command.exe) didn't help me (at every command it returns a "FAIL" message, my phone is recognized by Windows by the way).
So I couldn't get into Fastboot by following this Guide.
Hope it works for others, waiting for results!

You couldn't get into fastboot or u couldn't flash anything in fastboot? I cannot make my device recognised in adb too, but it is recognised in fastboot. U need to have the adb and fastboot setup in your pc. But I couldn't flash anything in fastboot as it shows my device is locked although someone said, theoritically it was supposed to flash system files through fastboot.

If we can get into fastboot, can we then do something like
Code:
fastboot boot recovery.img
to get into a custom type recovery and do a backup? I'm on the AT&T H810 version, locked bootloader, I don't know if that means a big fat NO lol or if this method of getting into fastboot mode would even work on my variant.

no one should be wiping laf or recovery to get into fastboot. it's a dumbed down fastboot that doesn't let anything flash or boot. the directions I gave OP were in a PM as a last resort because he was stuck in download mode with no booting and wanted to try fastboot. It was never meant to be suggested in public to users who might think they can get anywhere with it.

Holly molly sir! You are a legend. Long story not so short. My lg got the bootloop bug. Took 2 months to fix, but apparently they changed my locked to three uk H815 "eu open" motherboard with actually unlocked one. So I was finally able to unlock boot-loader, root and **** up (LOL). Apparently I didn't install twrp properly (you'd think "fastboot boot twrp.img" would not install it but run it once) And i was following this to get Android M on. But it requires reboot before boot-loader is flashed. Right when i clicked reboot i figured it wont start in twrp but in stock recovery. So I couldn't even get proper bootloop, it would cut half way into the LG logo. I reckon kdz-ing would havedone the trick, but god it takes ages to DL the kdz file. So in the mean time i found this legendary post. The odd thing was i had to click Yes, on the factory reset screen, but it got me to "Fastboot mode started" and from there i booted into twrp and finished what it had started, currently its Optimising app 35 of 55. Nice one OP, Nice One!

But there are too many bugs.
So I want to downgrade.
I want to go back to 7.1.
I tried to find a way.
I do not really know.
Press Volume Down + Power to enter fast boot mode.
With ADB, if you use 'fastboot devices'
Nothing happens.
Developer option, OEM off, all done.

Download current build from link provide above ^^(current build)
extract the files to your "adb/fastboot/platform tools folder on pc"
connect the phone to computer using usb cable.
Open adb on computer
type adb reboot bootloader
when in bootloader verify fastboot works
"fastboot devices"
if your device shows up double click the flash all script for your OS.
Profit

Hi.
Recently I decided to flash lineage os 15.1 on my MiA1
For that I have downgrade to Android nougat.
After downgrading I booted my device.
After setting up device I booted device in fastboot mode to follow further steps like flashing TWRP and all but the problem is my device goes in fastboot mode and it is not identified by abd and after that it is automatically getting restarted and is not holding in fastboot mode.
Please help??
Odd issue. What are you using to flash? If you are using XiaoMiFlash.exe, you'll want to try the (THIS WILL REMOVE ALL YOUR DATA) "clean all" option. Please note that this removes all your data.
I have used MiFlash tool for this and now My device automatically reboot from fastboot mode so I am not able to use adb as well to flash rom or twrp also Now MiFlash tool is not recognising the device.

Oh. If it's booting up fine, then you shouldn't be worried too much.
If it keeps restarting in Fastboot mode, it could be a driver issue which is preventing your PC from recognizing your device and vice versa. I'm on Windows 10 which installs drivers automatically so I've never had experience with it.

I think that's expected behavior? If it doesn't recognize itself being connected to a device, it'll exit fastboot mode.
I think you need to connect it to the USB cable and into your PC for it to not restart/power off.

Once fastboot mode is on the device is automatically restarted in about 10 to 15 sec and within this time MiFlash tool or adb cmd prompt bot does not recognise my device.

Your device doesn't get detected in your CMD prompt when it's in fastboot AND you type "fastboot devices"?
If it doesnt then you might have flashed something incorrectly.
Also, make sure to have your android drivers up to date in your pc. It's very, very likely that you don't have them installed on your PC, or they are outdated. See this: https://developer.android.com/studio/run/oem-usb.html

I have faced this issue. Yesterday i dirty flashed a custom rom. but i forgot how to dirty flash. i just simply flashed the rom and restarted the phone. it was mandatory to flash custom recovery and gapps after flashing a rom dirtily or normally. but i didn't. After the reboot completed, i remembered that i didn't flashed the twrp and gapps. So, i go back recovery mod, guessed i could flash twrp now. But i didn't see any custom recovery on my phone. But the phone boots, and i can use the phone. Still, i'm on that phone, while i'm typing this comment. i didn't lost my data cause i flashed dirtily. But the problem is, as i didn't flashed gapps or magisk (for root access), now i can't use google apps like, play store, and more. As i don't have root access on my phone so, i can't run flasify, to flash custom recovery. neither i can run other apps that need root. As i didn't flash custom recovery, now i can't flash gapps, magisk and whatever that needs a custom recovery.
I told some rom porter about the matter. They told me to flash stock rom. So, i was trying to flash stock rom. but flashing stock rom requires a fastboot mode. But my fastboot logo doesn't appear and it's blank. I told this to a rom porter. But he said, He doesn't know about that and he can't help.

Can you use fastboot (volume down+power)? If you don't have Android SDK, then install Minimal ADB and Fastboot, open cmd in that directory and type "fastboot device" (or "fastboot devices"?) while phone is connected via USB in fastboot mode. If it displays your phone's serial number, then you can use fastboot. If it doesn't show you anything, then I think wiping your phone in recovery or performing a clean flash through Mi Flash is the only way. However, if you can use fastboot, then the next step would be booting into TWRP... but we'll get to that once you confirm if it's working or not.

If it doesn't show you anything, then I think wiping your phone in recovery or performing a clean flash through Mi Flash is the only way. However, if you can use fastboot, then the next step would be booting into TWRP... but we'll get to that once you confirm if it's working or not.

Hi,
i have checked by typing command---fastboot reboot and my phone reboots and hangs at android one screen so that means i can use fastboot but strangely didnt see in fastboot devices but i found output for fastboot oem device-info where device unlocked shows false and other status.
If this is enough for using fastboot to boot into TWRP?

Actually bad news is that to boot into TWRP you need to unlock your bootloader first (fastboot oem unlock), but to do that I think you need to have enabled "OEM unlocking" in developer settings (though strangely I am unlocked, but for me this option is disabled). Try unlocking anyway. If it doesn't work, then I would follow this guide to clean flash official firmware with Mi Flash Tool. Be warned, you will lose all your data if you manage to unlock your device.

Hi,
Is that mean i will still loose all data even if i unlock bootloader?
And i am unable to unlock bootloader by command. So only option i have now to do factoryreset/wipe data?
So after factory reset again i need to flash the ROM ? Because if again i need to flash ROM, i understand the prerequisite is Bootloader unlock which will create issue again.
Please suggest.

Yes, unlocking bootloader wipes data.

No, if you wipe your phone through recovery you won't need to flash anything. It just deletes all your stuff without touching the system.

Guys pls help me i got stuck on boot logo i want to flash stock rom pls help me
I'm in the same boat. Unable to access developer options as phone won't boot and its stuck at the android one logo.
Fastboot oem unlock gives error Flashing Unlock is not allowed.
Is there anyway around this?
I'm still stuck with my Mi A2. I didn't enable OEM unlock or USB debugging and now i'm stuck on android one logo with only option is to boot into fast-boot mode. All commands and tools i try I get error stating unlock is not allowed in Lock State.
I bit the bullet and ordered an EDL cable so we'll see if i get anywhere with that. I've read that newer Xiaomi devices wont work with EDL cable and only option is to use the test point method....not sure how accurate that is but guess i'll find out whenever the cable gets here.

You can try fastboot oem edl
To put the phone in EDL mode without specific cable
However why not wipe data from the recovery?
Just use fastboot reboot recovery

Thanks for the suggestions. I know when I ran fastboot oem edl previously I get message stating device already locked.

If you see a triangle, you are in recovery mode
You need to press a button combination to see options, Search on Google for that
