I would like to know if there is ANY way to unlock bootloader of G4 H811 which is currently on version 10N? I have gone through several threads in this forum but nothing worked. "adb reboot bootloader" only restarts the device. P.S. the phone is rooted already, but still It's unable to update to marshmallow.
Here is what I have tried to update to marshmallow:
1. LG Bridge: It downloads update "H81520g_00_0720.kdz" which i think is wrong version and fails to update.
2. LG Up tool: I tried "H81120o_00_0613.kdz" but my PC won't recognize the devices after rebooting to fastboot mode. Obviously I have the drivers installed.
3. TWRP Installation: I tried installing TWRP through flashify, but it also failed due to locked bootloader.

no you must be on MM. and theres anirollback.. wich means you can not downgrade
so.. (10n and 20i are V2) and (20-o-p-q and r are V3) so you can unlock bootloader on 20i.. and you can downgrade to lollipop.. but if you dont care about lollipop then upgrade to lastest 20r and unclok bootloader and install twrp.. but you cannot go back to any version below 20o.
if you are in 20i- or the others 20-o-p-q-r you can follow this guide.
if you try with 20o-or any other say 20r .. you follow same procedure only you dont use 20i. for all unlock is same procedure. but using either 20i... or 20o-p-q-r.
steps oem unlock .. also you need LG drivers and minimal adb fastboot .. if you dont have adb.

Thank you for the details Raptor Please correct me if I'm wrong, you mean to say I can upgrade it to a version from 20p to 20r but I won't be able to downgrade back to lollipop right? That's okay, I just need MM anyhow. I found the thread https://forum.xda-developers.com/tm...-lg-g4-h811-20r-stock-rooted-rom-kdz-t3545130 that contains 20r images, but again how am i supposed to install them if my phone is not detected in fastboot mode?
Yes, I have the latest android SDK, and drivers, but still LG UP won't detect it once it gets into fastboot mode. I have checked the Device Manager in PC, and there are no any unknown devices.

yes if you want to unlock it yet also want to go back to lollipop use 20i thats V2 and so is 10n. once you flash either 20o-p-q-r then you in V3.
step 1.. download the KDZ file in that link..
step2. download LGUP.
step3. unzipped file the KDZ
step4. turn off phone... then press volumen up and insert usb cable.. must be usb por 2.0 and no windows 10....if am correct... then browse for file in LGUP once you select file.. exit LGUP... then open it again.. now tick refurbished and start..
this will update fresh clean installation of 20r.
then follow the procedure i the link i posted it works for 20i-20o-20p-20q or 20r.. just dont flash 20i. its just a guide skip when it says to flash 20i that part you already done it with 20r.
follow steps and youll have unlocked bootloader install twrp. and have fun.
hi guys,
yesterday i installed the oreo beta on my VTR-L29 but then i brickedd it *cry*. unfortunateley the unbrick methods found here in the forum don't work because the oreo update made some changes in the system file structure...
has anyone an idea what to do?
maybe someone can provide me a recovery image for twrp? (one for oreo, otherwise it wont work) so i can give this a try...
after over 10 hours of fiddeling around a found a really easy solution:
most of you know HWOTA helps with this, but the "normal" version wont work after flashing oreo. but this version is flashed via twrp and is still working!
but you will need a oreo compatible twrp, which you can find here
i know the links are to mate 9 software, but since the p10 and mate 9 are nearly identical, it works on the p10 as well
can you post the step by step guide?
i am on oreo 8.0.0.046 and want to flash another version, or downgrade to nougat because few things don't work on this version
i dont know if downgrading works, i just reflashed the latest oreo.
accordingly to the first link it should work, just flash the TWRP from the second link and then follow the instructions from the first link.

i did sucsses to install twrp but on the second step, when i press on install on twrp, the phone restart to erocovey and failed to find the files. what am i doing wrong?
i think that i am stuck with that version forever....
if you reboot to erecovery, you have not successfully installed twrp. you have to install it with "fastboot flash recovery_ramdisk <path to twrp>"

EDIT : the process is sucsses, but its the same version.... 8.0.0.046
Bricked, no TWRP access, any ideas?
Hi.
I know this about a P10, I have a P10 Plus (VKY-L29C605), but the process should be similar, I think.
I bricked my phone after succesfully upgrading from B174 to B321 using HWOTA. After which I decided, since I was at it, to flash the Hyperplus Kernel. This led to a bootloop. To fix it I decided to just go ahead and HWOTA B321 all over again and get over it, and would have probably gone just fine, except I decided to rebrand (C605 > C432) while I was doing that, silly (no, stupid) mistake. This led to the brick I am currently expriencing, I have no recovery access, erecovery or TWRP.
So now I am left trying to unbrick the phone. I extracted the UPDATE.APP for both update_all_hw.zip and update.zip using the Huawei Extractor Tool with no difficulty, except unbricking methods ask for boot.img, which I could not find, so I went along without it and flashed: cust.img, recovery_ramdisk.img (using fastboot recovery_ramdisk command for Oreo), and system.img. All of the commands completed succesfully, but no shebang, still bricked and no recovery access. I figure this has to do with the rebrand as the result after executing the command "fastboot getvar vendorcountry" shows the rebrand pulled through (hw/eu 432).
I am currently downloading HWOTA8.zip (3GB worth of download) to see if I can do something it. I am also downloading the L29C432B360 OTA-FULL, since I believe I am not getting any progress becuase I used the updates for L29C605B321.
The kind people at funkyhuawei told me they could fix it with their tool, but I don't have the money for that right now.
I will post updates, but any ideas would be greatly appreciated.
Many of us have posted over this in the last couple of days. Seems like Funky Huawei unbrick tool was the mehtod to get it work for me. You could try that!
or use dc-phoenix for me it worked (= in the moment i try to capture the usb ports kommunikation so i have the tool with the aktual firmware longer for 3 days :silly:
would first give dc a try 20 bucks for 3 days is ok i think (=

Must download some software for your phone, unzip update.zip, decompile UPDATE.APP to .iso files, (like recovery.iso, system, iso, vendor iso, boot iso) use fastboot and 10 minuts job, I brik my device over 10 thimes, and repair it.
So I was able to get the C432B360 firmware and I flashed it, but no I can't enter recovery mode because the battery is low (red lightning bolt/red led flash). Anybody know how to charge or force recovery mode boot from fastboot?
If anyone needs, can use my DC-Phoenix account, I don`t need it anymore.

Greeting,
Can you explain the procedure of how to do it?
Thank you
Hi, I'm in a bad situation. My honor 9 lite (Europe) has no OS, frp lock. But it does have TWRP installed.
My question would be, since I can't flash an OS (given the frp lock) via fastboot, would it work via TWRP? Or should I just give up and buy a new phone?
Thanks a lot.
Best
Since you have TWRP, try using HURUpdater tool. It is compatible with H9L.

Hi,
thanks a lot for the tip. Unfortunately, I keep getting an error when flashing following the instructions.
I discovered that nonetheless I can flash roms with TWRP. There is one particular rom, this one https://forum.xda-developers.com/honor-view-10/development/rom-t3753555 that works particularly.
However, my device with that rom keeps giving me an error "bluetooth keeps stopping". Any way to solve that?
I really don't know a solution.
Can't you enable OEM unlock in settings/developer options? so that to make frp unlocked?
Yes.
After that, I was able to finally flash stock rom
However, there's a new issue: wifi doesn't work. It actually seems like whatever rom I flash, wifi won't work the slider turns off as soon as I turn it on
Did you wipe data/factory reset through eRecovery after flashing? That is important in most cases!

No I did not. I think I used TWRP to do that. Will do with eRecovery next time and update you
I am still without WiFi.
I think the problem lies in the fact that my stock ROM comes from here: https://forum.xda-developers.com/9-lite/how-to/guide-unbrick-device-recover-bootloop-t3772563
I had oreo 8.1 before brick, and the rim above that I flashed is 8.0 and Indian version (not european). That maybe could explain the issue.
Problem is, I would need a system.img stock ROM to file and I can't seems to find that. In Huawei firmware finder, I only get update.zip kind of files and TRWP returns error when flashing that or when I use the HuRUpdater tool.
Also, I've noticed it's not just the WiFi, but also security options and themes for some reason
you need a working frp image which in twrp can flashed via dd... so the frp lock is gone...
In telegram group you can find image.

The system.app file you search for is in the update.zip file you get and you cannot flash update.zip directly from twrp, you need HuRupdater for that and the dload method doesn't work for almost anyone including me.
And you need correct the firmware for your motherboard if you want your phone to work properly.
First tick oem unlocking in developer options. Then unlock fastboot and flash TWRP.
Since you are able to boot up check your varient, the complete one not just the LLD but the rest too. Search for it in Huawei firmware finder and download the latest firmware for your model. You'll get 3 links and you'll need all three.
Download HuRupdater 0.3 zip and then rename the 3 files you got as told in the HuRu instructions. get twrp image and rename it to recovery.img and put all files in the same folder.If you want to completely revert to stock you don't have to have recovery.img but keep it just in case.
Then flash HuRupdater using twrp. You should be up and running if you did everything right.
You can then remove the recovery.img and then flash again using HuRupdater and relock the fastboot too later if you wanna play things safe using fastboot relock bootloader 'your code' .
please help me, honor 9 lite last night my flash rom forgot the data format so now can not boot into the operating system, locked FRP, can not enter the TWRP.
Hello, I know it's been a long time. I put the issue aside for a few months as I had another phone to use in the meanwhile just wanted to let you know i Just did the procedure you described and it worked perfectly! The phone is back to life :laugh:
I messed up my v40 405ebw, itry to cross flash it to korean version 409n using lgup partition dl but now it is not usable, an error always pop up and I can't access about phone, i try to flash it via refurbish but it includes error not support for cross flash please help me to restore my v40..
you may download and install the below LGUP, then replace the files in the lgup forlder in your program files with the one in "LGUP_to be copied into LGUP folder", then run LGUP you'll be able to crossflash to your European kdz again.

Picked one of these up on the weekend and was looking at going to linageos.
patched upto latest, and went through the linage install steps but missed the step on after installing the bootloader unlock software going into options and unlocking.
Went ahead and installed the linage recovery but now just get a basic screen with options of
START
RESTART BOOTLOADER
RECOVERY MODE
POWER OFF
All options loop me around back to the same place.
trying to start, ends me up with a your device is corrupt message.
I've been trying to get it back to factory.
QPST and QFIL can't see the device.
i can see the device in fastboot.
have downloaded latest firmware.
extracted using payload_dumper
no recovery.img on there.
updated the boot.img, vendor_boot.img dtbo.img from Question - My Asus Zenfone 8 flip is STUCK in CSC FASTBOOT MODE PLZ HELP!, RAW FIRMWARE ANYONE??? | XDA Forums
but no luck as there is no recovery.img in the firmware package.
Any ideas?
Somewhere there was FW update (at least I remember .115) to downgrade from beta A12 to .115FW (android 11). And it could help you I hope. At least you can try.
Yeah all is not lost. Etract and run this to get you back to factory stock. If you can't connect with fastboot, it's a driver issue and you'll just have Google it and pay around until you get the driver right.
Firmware I'm on would be WW-30.12.112.62 i think
is that android 11?

I was once stuck in a bootloop after flashing a custom rom and did a fresh install of official firmware.
Go to this website https://www.asus.com/Content/Android-12-Beta/ and scroll down to "How to opt-out and revert back to Android 11" section. There you can download the firmware file and a 3 step instruction.
By doing so I was able to bring back my phone.
The version of the firmware is from 2021/09/03 (WW-30.11.51.115) so you just need to update to newest release and everything should be fine.
