Yes, I noticed that from time to time, in bootloader mode, it is written unlocked, but as the device bootloop (bug) I believe it too. so
I retype systematically the bootloader code to open.

If you have your bootloader unlocked (if you don,t have it, unlock it) and flash TWRP. After that, flash B130 for your VNS-L31. Done.

Unlock yor Bootloader again. And try flashing again.
Have hade the same problem. My bootloader showed unlocked, but he was not.

Shut down your device. Press the switch off for 10 secounds.
When the phone is off, swith on and same time with vol + without usb-kabel, and otherwise try it with usb-kabel.
When you stock recovery starts. You can try a factoryreset.
When you Revolution recovery starts flash oem.info again and perform the dload methode with your right MM UPDATE.APP.

OK. Go to bootloader and flash:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
extract this files with: Huawei Update Extractor from your Original UPDATE.APP
system.img is loading in steps and need much time.

Hi guys, i have the same problem after doing some ****, flashed stock rom from lineageos 14 and a lot of things that i'm trying now to unbrick my phone... i cant enter to the erecovery with the 3 buttons method, wathever i do, and i dont have any idea on how to unbrick my phone... I hope someone could help me

Messed things up with upgrade/downgrade?

My wife got a P9 Lite L31. I wanted to upgrade to Nougat. I finally succeeded, but after that I messed things up. I tried to do a clean intall with a update that wasn't ment for this.
In the beginning I could still enter the Nougat recovery, but I wasn't able to reinstall the update.zip. The device wouldn't boot, etc.
I tried to do many different things, but at this moment I cant enter TWRP anymore, I can enter fastboot and is says:
PHONE Unlocked
FRP Unlocked
But flashing an other TWRP recovery doesn's work because I get an error:
(Remote: Command not allowed).
Also relocking the bootloader doesn't work because is gives the same error as the one above.
I can't flash a OEM file through fastboot because it gives the same error as the one above.
I can't use HiSuite because it says it does not support the phone.
I don't know what else I can do right now.
I tried the 3 button method, but I can't get in the official recovery. The phone reboots to some kind of recovery where it wants to update the recovery through wifi, but it ends up with an error that it can't fails to get the package info. But there is no option to do a factory reset (I've put the MM update.app file in sdcard/dload folder).
Any ideas what else I can do to recover the phone?

Unlock the bootloader again.

Ok, did not expect to do that again, but I did it.
What's the next step? flash a nougat recovery? flash a oem recovery?
Fastboot now says:
Error!
Func NO: 11 (recovery image)
Error NO: 2 (load failed)
Looks like fastboot isn't recognized by the computer anymore after the re-unlocking of the bootloader.
Windows device management also doesn't see the device. Not even as an unknown device.... Looks like the bootloader unlock completely bricked the device.

Well.
You must change your motherboard.

Try to discharge your battery by leaving it on Fastboot mode.
Charget the batery and let it boot itself.
If it boots in the software, it will be very easy to fix. If no, then changing the motherboard is required

To be honest, nothing.
It can do two things, you can let it boot and then it says it's booting, and that's it (after the warning that the bootloader is unlocked), or I can boot into fastboot but the phone is not detected by the computer. Device manager doesn't see the device at all not even as an unknown device. Nothing. So no way to flash anything using fastboot. KI also can't get into the fastboot&repair.
So yeah, I decided to send it in for repair.

Lenovo K6 without OS

Hi, I already had my phone rooted and with TWRP installed, but I needed to restore my phone. First I did this trough the system, but I noted that a lot of old files still were there, and I went to TWRP and did a wipe, but selected /system and /cache, now I don't have a OS on my phone.
The phone doesn't turn off, everytime I try to power off, he turn on again, and stay on Lenovo logo. The only thing I can acess is Fastboot mode (via Power down + power), I cant acess TWRP trough the phone, but I found a .bat file, that when I'm in fastboot mode, it flashes twrp on my phone and I can acess it . The other problem is that I always get an error when trying to flash any rom. Things like Error:255 or ".zip file not valid". Tried 2 roms and nothing.
Can someone please help me? I would prefer a stock rom for Brazil, but now I just want any rom, dont even mind if it's not stock.

Error 255 is caused because you are trying to install a 64bit ROM over TWRP (32bits), you need to upgrade TWRP to 64bit, just so you will be able to install a ROM. Remember that you should use Gapps in 64bit [ARM64]
TWRP: https://dl.twrp.me/karate/twrp-3.1.1-1-karate.img
Gapps: http://opengapps.org/ (ARM64)

I already had this version of twrp, but downloaded anyway and got the same error when tring to sideload a ROM "Updater process ended with ERROR: 255" . I don't know what to do anymore, I tried with 4 different ROMs, also I searched for a method to erase the lines with asserts on "update-scripts" in META-INF, but then I got a "Invalid ZIP file" error.

Try to go back to the 32bits version and erase everything and format the data and return to the 64bit version because here I had this problem it was because of the TWRP that I was using, it was the 32bits version, after that I upgraded to the 64bits version I did not have this problem. Remembering that in the site https://dl.twrp.me/karate/ has two versions of TWRP, the version twrp-3.1.1-0-karate.img is 32bits and the version twrp-3.1.1-1-karate. img is 64bit.

MAN, the ERROR: 7 now could be solved by deleting the lines with ASSERT in "\META-INF\com\google\android\updater-script".
So, thanks for helping me, the problem with 64/32bits worked. I'm really glad that this worked, had stuck for 3 days without OS, now i'm never messing with this stuff again haha.

Dont forget to reboot again into twrp - after flashing 64bit twrp . This is a step that is very important if you will not reboot your phone into twrp after flashing 64 bit twrp then , it will keep showin you the error 255.
So check that .

Use erase the data from wipe option then you will be able to install rom and g-apps.
Every time you will need password, I don't know why but after erasing data you install all files otherwise you need to erase data again and again

I Faced same problem. It's ok that your phone is in weird state for time now. And also possible to recover.
Hopefully you have adb-tool, custom-rom & gapp, twrp.img on your PC.
1) Boot your mobile in fastmode using Power ON with Volume down key for 5 sec (Lenovo log with left hand side sayinh fastboot mode)
2) Connect the mobile to PC using USB & Go to adb tool folder. Open command prompt in this folder & Execute the follow step by step execution
fastboot oem reboot-recovery
3)Wait for mobile to boot in to recovery mode with TWRP
Now need to flash custom-rom followed by gapps installion.
I) You can use pendrive with otg to flash custom-rom followed by gapps
OR
II)You can use phone storage/SD card to flash the custom-rom followed by gapps
OR
III)adb sideload command as fallow
a)In TWRP recovery on mobile, goto Adavanced->ADB Sideload & Swipe to start the sideload
Now on PC execute . Specify custom rom path inside ""
adb sideload "C:\adb\images\MyCustomROM.zip"
Have a patience to complete the operation.
Click back for Adavanced Menu again.
b) Select ADB Sideload & Swipe to start the sideload
Now on PC execute . Specify Gapp path inside ""
adb sideload "C:\adb\images\open_gapps-arm-7.1-pico-20180611.zip"
c)Have a patience to complete the operation.
Once complete go to TWRP Screen.
d)Now go back TWRP main menu & select wipe->format Data.
Go to Reboot->system.
How to install TWRP if no OS there
1) Boot your mobile in fastmode using Power ON with Volume down key for 5 sec (Lenovo log with left hand side sayinh fastboot mode)
2) Connect the mobile to PC using USB & Go to adb tool folder. Open command prompt in this folder & Execute the follow step by step execution
a) To check the device is connected to PC or not
fastboot oem device-info
b) To flash the recovery. Give twrp path inside the ""
fastboot flash recovery "C:\adb\images\twrp.img"
c) To boot into recovery mode
fastboot oem reboot-recovery

Bricked my P10 lite and nothing seems to work

A while ago I installed TWRP and rooted my WAS-LX1A and everything worked perfectly fine except that I couldn't install updates. Today I tried to install install a more recent rom and, as expected, it failed. So i tried to install it manually, unpacking boot.img, system.img and recovery.img from the update.app file and flashing them using
Code:
fastboot flash *type* *file*.img
I was able to flash boot and recoverybut when I tried to do the same on system it got stuck and I was forced to interrupt the process. Now my device is constantly stuck on
Code:
Your device is booting now...
and I can't access recovery nor fastboot and adb isn't working:
Code:
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
I tried using the dload folder method in a FAT32 formatted sd card and every sort of button combination but i'm still stuck at the same point. Anyone can help me?

luis ota doesnt works due to root a custom recovery, i recommend you access to twrp, next:
1- Make a backup only of oeminfo(coy to safe place), download oeminfo ss or ds depending your device, extract and copy/replace oem to the original oem
2- Downloaded servicerom b182 or b183, extract and copy all file and folder(was-lx1a folders and update.app), to dload folder on your sdcard.
3- Now press restore oem and shutdown when it finished, now do 3btns method.
Alternatevility could uninstall adb and reinstall, check if device manager has traces of device or adb and remove too

Didn't work and now the phone is locked and I've lost my unlock code. TWRP also isn't working, as holding pwr+volumeup starts erecovery while the booting screen changed from "Your device has been unlocked" to "Your device has failed verification". Any tips?

mister if you frp(oem is unlocked(red color)) you can solve with dload method and servicerom b182 or b183, other method is dcphoenix(paid)

oeminfo: backup insdcad(copy to safe place), with the downloaded oeminfo just copy/replace and then restore.
srom: create one folder called dload in sdcard, then extracted the service copy all was folders + update.app(they are inside of dload folder) to the dload sdcard
alternatively you try with dcphoenix and/or dcunlocker(paid both)

[working & tested] unbrick bnd-l24

Many users on this forum have a bricked Honor 7X (BND-L24 variant) and haven't found a working guide to breath life back into their devices. Fortunately, I found a method that appears to have fixed my BND-L24 that was running on oreo. Maybe it will work for you too. Nougat users, feel free to try this method on your devices. Just know that I am not responsible for any damage or anything else should your bricked-phone-situation go from bad to worse.

1. microSD card ---> You need one of those adapter things to access the microSD card on your computer. We're going to be moving files to this little guy.
2. TWRP recovery --> We're going to be flashing a zip so stock recovery won't work here. Don't worry, once we flash the zip, TWRP will be gone
3. HuRUpdater_0.3.zip --> I know there is a HuRUpdater_0.2.zip too but I used HuRUpdater_0.3.zip when I unbricked mine so . . . that's what we're gonna use. You can download it here: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279 Don't forget to thank the developer!
********STEPS********
1. First things first. Download these three files:
update.zip
update_full_BND-L24_hw_usa.zip
update_data_full_public.zip
2. Once downloaded, rename them as listed here. THIS STEP IS NOT OPTIONAL
update_full_BND-L24_hw_usa.zip -----> update_all_hw.zip
update_data_full_public.zip -----> update_data_public.zip
DO NOT RENAME update.zip
3. Make a folder on the microSD card. You can name it whatever you would like. For the purposes of this guide, I named mine "Recovery". Move all four of the zips (or archives, whatever you wanna call them) that you downloaded to this new "Recovery" folder. Then eject the microSD card.
4. Insert the microSD card into your paperweight, I mean bricked Honor 7X. Then boot into TWRP.
5. In TWRP, tap on "Install". Then browse to your external SD card and tap on "HuRUpdater_0.3.zip". Swipe to flash it.
6. Once everything finishes installing, tap on "Reboot" then "System" (I have no idea why you would want to install the TWRP app if you don't have TWRP anymore but . . . to every man his own). When the unlocked-bootloader-warning screen pops up, press and hold the volume up button to boot into eRecovery. Perform a factory reset from there.
7. After the factory reset is completed, say hello to your now fully functional device.

Giving this a try right now. Will report back. Thank you so much!

After flashing HuRUpdater_0.3.zip and holding volume up, it just boots back into TWRP?
Edit: Never mind, I'm dumb and didn't press volume down during the flash.

IT WORKED! Thanks so much!!!!!
One error in your directions though:
update_data_full_public.zip -----> update_full_public.zip
should be
update_data_full_public.zip -----> update_data_public.zip

Any known way to get TWRP first? I don't have it and erecovery seems to not install firmware

Download HWOTA8. After you extract it there is a twrp image in it. There is also a stock recovery image in it incase something goes wrong. There is a thread here on twrp. You will come across a twrp image by sudeep. You can use it too. Although it didn't work perfectly for me. Use adb or multitool to flash them

my phone is bricked... thus the bootloader is locked... i cant flash to it.

Bricked as in display won't turn on?

when i turn it on, it comes up to erecovery, "download latest version and recovery" will connect to wifi but fail to download. Multi-Tool says bootloader is locked as well.

Try to use the service rom.
The erecovery thing does not work, exceptaybe on Chinese version of rom, it seems

Thank you so much! I have tried every other method on this forum over the past few months and wasted countless hours. I could not get ANY other method to work. This worked perfectly the very first time. Thanks!!!

Not sure what you mean by use the service rom... I can't flash the ROM because the bootloader is locked.

The service rom does not need unlocked bootloader.
You do need your unlock code though.
Service rom BND-L21C432
https://www.androidfilehost.com/?fid=11050483647474828964
1. Unzip download
2. copy the dload folder to root of sdcard
3. power on phone holding all three buttons
4. After phone finishes and reboots, unlock frp and bootloader, if needed
5. Use Huru or HWOTA to flash correct firmware for your model/ region.

Is there still a way to get the code? I haven't been able to get it

****, I ****ed it up.
Started installing the file without first renaming. TWRP is gone and now I have no way install those files. bootloader is "soft" locked and I'm ****ed...

There is an option to use bnd-l21 service rom. Which will allow you to boot and unlock bootloader again. Then start over with hurupdater.

I got some errors when running the Hur Updater
I'm currently redownloading the files hoping there were download incorrectly the first time or something...

I finally got it working, but I can't install updates. Anyone else have this issue?

I need help
First, I did something and now when it boots it doesn't show the honor logo but it shows the huawei logo and can't progress farther (I swear I didn't try to install another OS)
Second, I can't access twrp but can access fastboot. I have downloaded twrp and was able to access it before I messed up even more to the point that it doesn't show the honor logo
In the fastboot screen, it says PHONE Relocked but when I type in fastboot oem get-info in the terminal of my computer with my honor 7x connected to it and fastboot screen it says (bootloader) unlocked ,so I'm not sure if the bootloader is actually locked or unlocked
So what I'm not sure about is what can I do to access TWRP. I tried installing it again but it didn't work either user error or it's just not possible to
All your help will be very appreciated because I don't have money to get another phone
i really shouldn't have done any of this knowing that I don't have money to get another phone
edit:
I don't think the OEM is unlocked like the thingy from the developer options because I don't see FRP in fastboot screen, just PHONE Relocked
