Bootloader unlock break functions - Huawei Mate 10 Questions & Answers

Hi guys,
I want to flash any of the openkirin roms but when I unlock the bootloader I have no more audio/sound anymore and also I can't make any phone calls.
When making a phone call I starts dialing and it makes connection but the other person on the line can't hear me and after a while my phone gives me an error saying there is no network connection..
After this the dialer stops and the pincode screen comes up and I have to enter my pin again..
I had RROS installed, it was working fine except the volume level was a little low so I started tweaking with default_volume_tables.xml and mixer_volumes_BLANC_ce.xml. I also installed an app called "precise volume" from the play store and directly after this installation the problems started. So after i revert to stock completely..
The phone did a factory reset lowlevel because i relocked the bootloader, after it reboots and everything back to stock all was working fine again.
Then i unlocked the bootloader again and flashed RROS and the problem is there again..
So locking gives me a fully working phone, unlocking breaks functions.
Anyone that can help me with this?

U can try to relock?

Have you tried re-installing firmware?
You could use TWRP with HuRUpdater.
Factory reset only wipes /data, but all other partitions are kept as they are.
Download TWRP by Pretoriano80: https://forum.xda-developers.com/mate-10/development/huawei-mate-10-pro-twrp-3-2-1-0-t3769904
And HuRUpdater: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
Easiest way for firmware is Firmware Finder app from Playstore. Search for your cust+build (for example BLA-L29C432B150, make sure you download firmware for your model and cust) and download FullOTA. Firmware is downloaded to /sdcard/TeamMT/FirmwareFinder/<versionnumbers>/
Make a new folder in /sdcard named Update, move update.zip, update_data_full_public.zip and (example, depends on your cust) update_full_BLA-L29_hw_eu.zip from the <versionnumbers> folder to the /sdcard/Update folder.
Rename update_full_BLA-L29_hw_eu.zip to update_all_hw.zip and update_data_full_public.zip to update_data_public.zip.
Place HuRUpdater zip in there as well. Reboot to TWRP and flash HuRUpdater zip and wait for installation to finish.

This worked! Thanks big time!!
Just a little off topic question..
As you are also in developing..
Do you know what sound mod is available for my device? Mate 10 pro now running on openkirin rros.
I used Ainur Sauron, i hear a clearer sound but still bt volume is low.
With my mate 9 i had the same problem but with this phone i had v4a working togerher with dolby atmos wich could boost the whole thing.
Any suggestions?
Best regards

V4A relies on drivers, but AFAIK those only work on Nougat for EMUI. :/ and no other sound mod does what v4a does.
As for your earlier problem; sound xmls exist in almost all partitions, and they do the same things. If you edit/break the one it tries to load first it will keep trying to load it when unlocked = broken sound/edited file is loaded.
If you lock bootloader, dm-verity is tripped and it won't load that file at all, but will load it from another partition where is not modified.

No storage after installing ROM

Goodafternoon,
I tried to root my Honor 7, but failed, don't know why, was stuck in a bootloop. Then I unfortunately deleted the whole system with TWRP recovery..
Then I downloaded the current ROM from a forum called modaco which seemed to be trustworthy and extracted it with HuaweiUpdateExtractor to then install the data with fastboot. I installed everything like system, boot, data etc. and everything works fine, except for the internal storage. Normally it should have about 13 GBs, but now has less than 3. When I go to Storage in the settings, it tells me I only have 3 GB internal storage in total.
As I don't exactly know how to describe this problem and therefore don't know how to google it, I ask you. If you need some more information let me know.
Would be very kind if anybody could help me or have some advices as I am not a real genius in doing such things.
Thanks!!
Hi,
First of all, is the custom rom deodexed ?
because on stock rom ( emui ) , you juste have to go into recovery, then factory reset, with a Custom, idk
I can only tell you before trying factory reset, make a full backup, then you could try

After manually flashing all the .img files you should perform a force update aka three button update, by putting the same version of UPDATE.APP from which you extracted those .img files.

So you mean, I have to flash the phone with bootloader with the extracted files from update.app and then put it on my SD card and manually update my phone with exactly that update.app file? or am I wrong? I already tried something similar, but couldn't find the option in my honor 7 in the update settings, to manually update (I have put the update.app on my sd card).
I tried to install another ROM (MoDaCo - ROM) with hard resets etc. but didn't solve the problem.
I do exactly have 3.87 GBs of internal storage after flashing the new ROMs or update.app files. I found somebody else with the exact same problem. He solved it by hard resetting his phone with the TWRP recovery, but didn't work for me. In that forum they told him, he has some "ghost ROMs" on his phone, from flashing his phone before.
If you do have any ideas or clues for me, don't hesitate to tell me. And thanks for your help!!

Yes, you have to do exactly that, flash files like cust.img, system.img, recovery.img, userdata.img(DELETES YOUR DATA), boot.img after extracting them using Huawei Extractor tool from UPDATE.APP.
After you do that follow below steps:
Put that UPDATE.APP in dload folder in your External SDCARD.
Switch off your phone.
Press the three button combo (Vol UP + Vol DOWN + Power).
After this your whole device will get flashed with that UPDATE.APP file you put in dload folder.
Try these steps, then tell me if the problem still persisits. I hope this solves it.

Sorry last question:
Currently I have the custom MoDaCo ROM installed (don't know if you know it). To follow the steps you mentioned above, do I have to get back to stock ROM first, or can I just leave ROM as it is and flash it?
Thanks.

No you can leave it as it is, it will get wiped in the process.

Thank you so much, everything went fine! Great!
To update my firmware in future, I have to download the new update.app and do the 3 button update, right? Or any other way? Are OTA updates no more possible?
Thanks again :laugh:
@Maxdr13 If you are rooted, then flash manually the img files then do a three button update, but if you are on stock ROM and recovery, just dong three button update by putting UPDATE.APP in dload folder will do.

and userdata etc. won't be wiped with the three button update (phone is not rooted) ? is there no chance to get back to normal status so I can update with OTA?
@Maxdr13 I can't confirm about userdata, as once I did a three button update my data was intact, but some people also reported that data gets wiped, and after the three button update you will get OTAs.

Honor 9 no OS installed, TWRP and fastboot with unlock still working

Hi guys, i got my H9 yesterday and because i thought i read enough on this forums i wanted to unlock it then install TWRP and install superSU to gain root access and stick with the stock firmware.
Unlocking went perfectly fine,phone booted to OS, than i flashed twrp 3.1.1-1 as advertised here and made a factory reset. Phone was stuck in bootloop for unknown reason.
I made several wipes and somehow managed to check all boxes in the wipe menu which erased the whole OS.
Now i read here that others have the "no OS" problem too but because i still have all unlocked fastboot and twrp i wanted to ask which method is best to flash back the original FW.
Which stock ROM is safe to install? i have european H9 is STF-L09C432B170 the right one for me?
Which method is the best to install it? Copy the 3 zips to internal stoagre via OTG device and install it out of twrp? I read that there is also a force method where users can push vol up, vol down and power simultaneously and enter the huawei install force mode.
I am quite sad that the phone was stuck in bootloop after twrp install and still dont know what caused it. When i install it from twrp there are 3 zips: update, data full public , hw eu. In which order do they have to e installed and is one of them overwriting the TWRP recovery?
Please give me a short hint/procedure, im quite afraid that i cant get my phone back to work and it is brand new. I dont know what caused the unsolvable bootloop.
Best regards and many thanks
Hi.
Check this:
https://forum.xda-developers.com/showpost.php?p=73334439&postcount=1
This help you.
Regards
thanks for the hint but i cant find a solution for me there.
ut this
i copied the 3 .zip files to internal today but TWRP doenst allow me to write them it fails with "write err errno 9"
then i tried to copy the update.pp in DLOAD folder on micro sd but this is not possible because filesize is over 2gb. i tried to format micro sd with twrp to exfat but it till doesnt work. please give me a little hint what to do im completely desperate about the situation.
Today i installed Huawei Multitool and extracted the .img file out of the update.app files, i was able to flash all 4, system, boot, recovery and cust.
Now the rec. menu is back to stock and everything got installed but the phone still isnt booting. i think it is because i missed the userdata.img which i cant find anywhere.
Other users here have the same problem. Is there a firmware package which includes all 5 .img data?
Best regards
i found the official huawei service full repair firmware with all necessary files for unbrick (system, cust, recovery, userdata, boot) flashed them via fastboot but stil device is "hanging" after the warning message that its unlocked. i think it is because i wiped vendor data in twrp but i cant flash vendor.img in fastboot. it is included in the fw package but cant be transfered to phone via fastboot. it stops at part 1/2 because the filesize allowd is around 470mb max but the extracted file has a size of 670. anyone know what to do?
Best regards
You need to go via the Rebrand way with no rebrand. I had the same problem and was trying to use the multitool without success. The oeminfo can be flashed alternatively if it fails during the HWOTA process.
https://forum.xda-developers.com/honor-9/help/how-flash-oeminfo-t3657499
ok i download all the folders with the .bat file. Then i download C432B150 from the czech site and add it to the update folder. Than i rename the 3 files accoding to the manual and run the .bat file but without rebranding right?
Des this tool any different than the HuaweiMultiTool or fastboot with flash command?
Best regards
I treid out HWOTA, the first step installing twrp is successful than i disattach usb cable as described and enter twrp. Then it says in twrp i have to connect again and press enter but then the bat file stops and doenst go on. i dont come to the point where i can choose rebrand or flash firmware.
Whats wrong here?
edit: i saw in the .sh file that the script executes wait_adb but my phone is not entering adb mode as it seems when in main screen of twrp. is this normal or do i have to set it manually in twrp
best regards
I was able to install the B130 now via 3 button recovery. Now im on B130 but cant update elsewhere. Also the 2 capacitive buttons are not working. Bootloader is locked again. Everything is stock and the phone runs great. When i update with the 3 buton method from external sd, which firmware should i use? i tried B150 full OTA but it aborts after 5% with an error. Do i only need to get a small OTA package now?
How can i put my cap. buttons back to work? Too bad only the 3 button method worked to recover the phone.
Best regards and many thanks.
I did the HWOTA with b120 firmware and then used firmware finder to update to b150.
The bug with capacitive buttons is present till Oreo. I use the home button gestures anyways.
Hope it helps.
ok, thats bad but they worked with the initial revision of b130 and b150 when i downloaded it OTA. Is this something like a fuse like.knox at samsung which happens at custom flashing?
Sent from my GT-I9300 using Tapatalk
the HWOTA method doesnt work, the batch file gets stuck after connecting the phone in twrp back to computer. in script it says wait_adb but it is not recognized somehow.
do u know a solution? anotherone here got that problem too.
im very afraid of that, i read here that everything related to twrp 3.1.1-0 and 3.1.1-1 is problematic a lot of people cant boot after installing twrp and can wipe whtever they want the phone never boots fully
whats the difference in the B130/B120 the phone came from huawei and the version flashed via tools? when i got it everything worked
i have this version.
ok so install twrp have frq and bootloader unlocked and then do backup out of recovery? with your file? can you provide download link? is this then a zip file?
I want to solve the thread and how i solved problem.
The B130 service firmware by huawei could be installed via 3 button method, than i was able to go up to the newest B180 via firmwarefinder and DNS method but with not working cap. buttons and flash etc.
Yesterday i installed TWRP 3.1.1-1(temporary) via HWOTA.zip method (ireplaced the older twrp in recovery folder) and successfully installed B120 and got the buttons etc working again. Then installed root and now system works fine and is rooted. My mistake was to install twrp over B130 or B150 which i downloaded OTA at the first day i got the phone. I tested this yesterday to install TWRP along with B150 and unlocked bootloader, infinite bootloop again. With B120 the TWRP 3.1.1-1 works out of the box without any loops.
The 2 trouble solvers where B130 service firmware and HWOTA with B120.
The external SD had to be inserted in card reader on PC because of the large filesize of the B130.
I would recommend to everyone before starting to play with the H9 to move the B130 folders to phone while it is still accessible. When everything bricks like in my case and u still have twrp than you can go to twrp main screen and connect phone to computer to rename the folder with B130 to "dload" and arrange update.app accordingly on PC or in TWRP file manager.
Can i set this topic to [SOLVED] myself?

Guide to rollback huawei p10 from oreo to nougat

Hi,(I am spanish sorry about my english)
after a long time searching how to rollback finally I have found the way thanking to this thread https://forum.xda-developers.com/p10/how-to/success-downgrade-oreo-to-nougat-t3729659.
In the thread the way to rollback isn't very extended explained so i decided to create mine and explain easy.
My phone is a Huawei P10 L29c432B.... .
Steps:
1- Download HWOTA8 from--https://drive.google.com/file/d/0B2D9GdWntw69U3N2aDEzZjY2S1E/view
2-Download Firmare L29C900B217 or L09C900B217 depending your model (only are 2 downloads) fromhttp://pro-teammt.ru/firmware-database/?firmware_model=VTR-L29c900&firmware_page=0
3-Delete the row "echo - - update_package...... update_data public. zip..." from the file "META-INF>com>google>android>update-binary" from hwota8_update.zip from the downloaded folder HWOTA8.
4. Create HWOTA8 folder and copy the following files: hwota8_update and MHA_RECOVERY8_NoCheck.img (from HWOTA8 folder), and the downloaded firmware files. After copu the firmware files you have to rename them one has to be named "update.zip" and the other one "update_all_hw.zip" (don't write.zip extension).
5- Now you have to rewrite the recovery with twrp, for that you have to go to fastbood (VOL- and Power) mode and connect to the pc. Then go to Uncompresed HWOTA8 folder and run "Replace_Recovery.bat" after that you will have the recovery TWRP installed.
6- Finally you have to to go to recovery pressing VOL+ and power button then go to Install adn search sd_external and inside HWOTA8 folder from sd card install "hwota8_update.zip". The device will resboot and start installing the nougat rom, but after that you will have to rebrand to L29c432.... to unlock all the functions.
That's all now you will have your device rollbacked from Oreo to Nougat.
Hi!
Thx for this guid, it seems to be clearly and good to understand! I have only one problem: i can not find the row "echo - - update_package...... update_data public. zip..." from the file "META-INF>com>google>android>update-binary" from hwota8_update.zip from the downloaded folder HWOTA8 for changing... ???
I tried with notepad++, but i can not do this... How did you get this step working?
Thx a lot!

You have to unzip the hwota8_update.zip file into another location, edit the extracted update_binary file and then repack the zip. The update_binary file in HWOTA8_<date>.zip is a binary file and shouldn't be edited with a text editor.

When the phone is off an you will hold "Power" and "Volume+" button to boot into TWRP, just hold "Volume+" after phone is vibrating... Then you will boot into TWRP...

The fact is that the recovery proccess is a **** in this model. Try to power completely off the phone and the Pess POWER + VOL+ when you feel the phone vibrates retire the press of power button and still pressing VOL+ button by this way sometime it goes ok. If TWRP load go ahead with the followings steps.
Other way it to reinstall again TWRP untill it loads.
Let me know if you suceed, good luck.
4. Create HWOTA8 folder and copy the following files: hwota8_update and MHA_RECOVERY8_NoCheck.img (from HWOTA8 folder), and the downloaded firmware files. After copu the firmware files you have to rename them one has to be named "update.zip" and the other one "update_all_hw.zip" (don't write.zip extension).
2. Download Firmare L29C900B217 or L09C900B217 depending your model (only are 2 downloads) fromhttp://pro-teammt.ru/firmware-database/?firmware_model=VTR-L29c900&firmware_page=0
non-functional link?
How exactly is it to be?

just to let you know that nothing worked,
went to a shop, they tried everything, uploaded older firmwares, but after that the phone died, only black screen, couldn't even switch it on.
warranty did the trick
the guys replaced the mainboard, nothing else helped
so i'm waiting now for the official update
Good day! Can I use this method for installing Official Oreo from Beta? What I would like to do, is skip the deleting of row then just flash the twrp and continue with installation process.
I'm on VTR-L29C636B361.
I would like to rollback to Nougat, for root reasons. I'm trying to follow this method, but I'm not able to find the right files. All I succeded to find is the "update.zip", from Firmware Finder website, but no signs regarding others mentioned ("update_all_hw.zip"). Where can I dowload the right files?
Moreover: I flashed TWRP 3.2.1. I would like to go back on stock recovery, but again I'm facing a lot of problems. I would like to extract from update.app I have (from "update.zip" above mentioned), but HuaweiUpdateExtractor gives me a lot of error. Any help?
Thanks!

I would like to rollback to Nougat, for root reasons. I'm trying to follow this method, but I'm not able to find the right files. All I succeded to find is the "update.zip", from Firmware Finder website, but no signs regarding others mentioned ("update_all_hw.zip"). Where can I dowload the right files?
Moreover: I flashed TWRP 3.2.1. I would like to go back on stock recovery, but again I'm facing a lot of problems. I would like to extract from update.app I have (from "update.zip" above mentioned), but HuaweiUpdateExtractor gives me a lot of error. Any help?
Thanks!

At the HWFF website the link leads you to you need to click the "filelist" (not only the "update"), that will give you links to all the files needed.
For the rest I am not sure, would also like to get back to the stock recovery but so far found no way to do so...

I can give you recovery.img and recovery2.img for VTR-L29C636B162. I flashed this and then roll back to Nougat (B172) with FF.

Hi,(I am spanish sorry about my english)
after a long time searching how to rollback finally I have found the way thanking to this thread https://forum.xda-developers.com/p10/how-to/success-downgrade-oreo-to-nougat-t3729659.
In the thread the way to rollback isn't very extended explained so i decided to create mine and explain easy.
My phone is a Huawei P10 L29c432B.... .
Steps:
1- Download HWOTA8 from--https://drive.google.com/file/d/0B2D9GdWntw69U3N2aDEzZjY2S1E/view
2-Download Firmare L29C900B217 or L09C900B217 depending your model (only are 2 downloads) fromhttp://pro-teammt.ru/firmware-database/?firmware_model=VTR-L29c900&firmware_page=0
3-Delete the row "echo - - update_package...... update_data public. zip..." from the file "META-INF>com>google>android>update-binary" from hwota8_update.zip from the downloaded folder HWOTA8.
4. Create HWOTA8 folder and copy the following files: hwota8_update and MHA_RECOVERY8_NoCheck.img (from HWOTA8 folder), and the downloaded firmware files. After copu the firmware files you have to rename them one has to be named "update.zip" and the other one "update_all_hw.zip" (don't write.zip extension).
5- Now you have to rewrite the recovery with twrp, for that you have to go to fastbood (VOL- and Power) mode and connect to the pc. Then go to Uncompresed HWOTA8 folder and run "Replace_Recovery.bat" after that you will have the recovery TWRP installed.
6- Finally you have to to go to recovery pressing VOL+ and power button then go to Install adn search sd_external and inside HWOTA8 folder from sd card install "hwota8_update.zip". The device will resboot and start installing the nougat rom, but after that you will have to rebrand to L29c432.... to unlock all the functions.
That's all now you will have your device rollbacked from Oreo to Nougat.

Hi, I have one question
Your phone was VTR-L29 C432 and you used the firmware of VTR-L29 C900, so can I use the C900 in any version to rollback and after that, what would be my version? C432 or C900?
I'm asking because for some reason I have VTR-L09 8.0.0.046(04VT) and I want to rollback, then rebrand and finally upgrade to VTR-L29 C432 with a custom kernel.
Thanks a lot!
This guide realy work ??
hello, I test by cons I have a problem, once flash hwota8_update.zip, it tries to restart in recovery and redémre on oreo, a solution?
Hello, I have a problem in the rocovery that I flash wota8_update.zip I have E: unknown command [errno]
Updater process ended with ERROR: 9
Error installing zip file '/external_sd/HWOTA8/update.zip
Maybe this is a silly question. Do we need to change the recovery file since MHA is a code name for MATE 9. P10 use VTR. Is it still usable?

[SOLVED]Going back from Custom Rom to Stock?

Can I actually just download the latest version via eRecovery and let the phone do everything on its own to go back to Stock? Or do I need to go through another procedure? Sorry for this stupid question but I can't find a guide on this particular thing and I'm concerned about bricking my device.
I'm running Resurrection Remix.

Why do I need Stock Recovery and can't stay on TWRP?
In RR's honor thread, it's at least stated that you'll need to flashback stock vendor partition if you want to come back to stock EMUI.
Stock Recovery and stock boot partitions may also be needed to be flashed back.
Thanks for all your relies. I used dload method now end everything went well without any problems. (firmware, then the vendor)

I used the guide and links provided on this post:
https://forum.xda-developers.com/honor-9/development/firmware-huawei-honor-9-stf-l09-stock-t3696892
I copied the dload/update.app into the root of my sd card and then rebooted my phone into dload (volume up + volume down + power). After it finished installing I interrupted the startup and rebooted into recovery where I did a factory reset and wiped cache. Then I removed the update.app from the dload folder, renamed the other .app file into update.app and did the same dload process again.
* Sorry for the bit complicated explanation; I meant copying the folder dload including the update.app into the root of the sd card. So was update.app not directly in the root but in dload folder.

Yes, already successfully updated EMUI 5 to 8 and eventually flashed Project Treble.
It's really working great so far, the only issue is the slow homebutton which I also mentioned in the thread.
Edit - Also, for those who are wondering because of my status bar:
Xposed Beta for Oreo as well as GravityBox [O] are working fine on this Rom.

Formatting with DLOAD method

Well, i want to exit of the list of safetynet, i tried magisk safetynet fix, nothing works, this happened after a HOTA Downgrade to Nougat because Oreo (EMUI B330) made me lose too much performance of my Mate 10 Lite (RNE-L03C178) and the APi interpreted the downgrade how a dangerous modification of the system for the apps or in other words a cheating action, i want to exit of the list of the api, i listened with a complete format of a device the safetynet will provide the apps (With SafetyNet block) back in Play Store.
Well i want to format my device with the DLOAD method or other method, could someone explain to me how to do it? (the process of the dload)
Sorry for the grand explanation and my too very bad english, my language is spanish...

In theory, you should download the stock rom from here: http://pro-teammt.ru/firmware-database/
Then, unzip the file and copy UPDATE.APP on your SD card. It has to be in a folder named dload on the root of the card.
Afterwards, reboot on download mode (turn off your phone, then, press volume up + volume down + power button until Huawei logo appears). This should trigger the process to install the app UPDATE.APP file.
If you have TWRP recovery, you will need to go back to your stock recovery (on that... please search on this forum).
I hope this helps!

I listened about to do this with the 3 update.app files
1.-update.zip
2.-update_data_full_public.zip
3.-update_full_RNE-L03_xxxxx_la.zip
Extract their update.app and install in order
Is this correct?

I tried to install it, it stucks at 5% and error message, what i do? Please help...
(Huawei MATE 10 ALP-L09) Hello, I tell you my situation, I am in the emui 8 version with cust 432 in the 150 sp1 version (xloader 1).
I want to try emui 9 so I'm going to switch to xloader 2.
I have the bootloader open and I'll leave it like this to update manually.
I'm going to use the HWOTA system, but when downloading the files of the latest version of emui 9 (version 159) I realize that 3 * .zip files are no longer the same as before, now only 2 files form it. The steps are the same? I put those two files in the Repack folder and then I go to the Ota folder and run the ota.bat ??
And another thing, should we rename those two files as was done before?
Thank you. A greeting.

Okay, but if You now running A8 , You can downgrade to A7 using HiSuite (Update > Other version) , or, if You have TWRP on board, You can downgrade flashing A7 firmware via HuRupdater 0.4 . It's strongly not recommended downgrade via dload method, it may brick Your phone.
