You idiot EMUI 10 cannot be bootloader unlocked, downgrade to EMUI 9.0!!!
If you want android 10 or even 11 you need something called a GSI, which I can inform you about it.

You saved me mate, was really a dumb move to go thought OTA without checking this point. Didn't now Huawei become that ******
Any advice for a good custom rom based on android 10 ?
And thanks again for your precious help

even better if it is android 11, i will try it
also have another dumb question : if i install TWRP on the EMUI 9.1 with unlocked bootloader, can i flash the emui 10 rom thought TWRP ? or this will brick the phone ?

that what i was thinking also, so bye Emui 10 for ever i guess.
what was the rom base on android 11 you are referring to ?

GSI Project treble rom.
The definition is https://source.android.com/setup/bu...tem image (GSI,or higher can run successfully.
Google's Offical GSI will not boot on huaweis though.
After unlock bootloader download this https://github.com/phhusson/treble_...v300.l/system-roar-arm64-aonly-vanilla.img.xz
use 7zip(https://www.7-zip.org/a/7z1900-x64.exe) to extract the file once and rename it to system.img and move to C drive WITHOUT under any folders.
Then go to recovery and factory reset, do not advance wipe, wipe>factory reset only
Then go to fastboot and
fastboot flash system C:\system.img
Failing to follow will result in rage!

Backup System, Vendor, Data and Internal storage in TWRP before doing anything will be a wise choice, in case anything is wrong.

Forgot to mention you must flash magisk in TWRP before installing rom, to disable AVB(Android Vertified Boot) so that a custom rom can be loaded.

Yeah for sur, i'm rolling back, unlocking BL then TWRP in order to get a full backup. I ll check the rom after that
A senior member refer to for EMUI 10 upgrading :
"Don't update system via OTA when phone is rooted or bootloader unlock. Flash firmware via erecovery and rooted again"
i think this is incorrect right ? he cant root again while on EMUI 10 ?

well i'm stuck with twrp not decrypting my data
i managed to install TWRP (several version), boot on them and so nothing to do
also can get root easily and magisk as i sideload zip from crypted TWRP version (worked)
tried the version twrp_clt_0.1.img from XDA stuck on TWRP starting screen
i'm almost giving up

Extract Android 11 Gsi, rename to system.img and move to C drive , not under any folders.
Go to fastboot then
Fastboot erase data
Fastboot erase cache
Fastboot flash system C:\system.img

SAFE rooting to HUAWEI MATE 9

hi guys ,
I`ve read this thread https://forum.xda-developers.com/mate-9/how-to/guide-how-to-root-mate-9-decrypt-data-t3569986
my ask : Does this rooting goes well with MHA-L29C185B172 ?
if not , then how can i root my device SAFELY ?
thanks all
one, post, no experience with rooting android phones, do NOT root this phone unless there is some important reason to.
do ALOT more reading before you even think about rooting
Thx to reply. Like the others i wanna root to have root apps in my phone ,
Thx . Wanna have apps requires root in my phone . That simple
You don't even need to decrypt if you don't want to.
Unlock Developer Options (Settings - About: tap build number until it says it's enabled)
Go to the Developer Options and enable OEM Unlocking
Unlock bootloader
Flash twrp 3.1.0
Flash SuperSU no-decrypt (https://mega.nz/#!lkV0jbYJ!b1h-5uVksvpt7rw0tRHV7Qxjwk2xkKox0w-iRsCLlbU)
Have fun.
For decryption follow the decrypt guide.
To undo root and relock (Bootloader Locked) flash a stock firmware using the Force flash guide under Guides or use firmware finder).
For Magiskv12 root you need firmware B182+
super!!! , I did unlock the device and flashed twrp ,then tried install SU but failed , that made me afraid of bricking if i did further action

Original SuperSU 2.79 won't install. We have no loop support in kernel pre-B182. And even with support it doesn't install. The one I linked is a phh supersu hybrid. It uses phh su's method of installing, but installs SuperSU.

Hi. I just happen to come across your post and noticed you said that there is no loop support pre-B182. I have the Chinese version with B213. Some apps, like Linux on Android need, unless something has changed, loop support as well as root. Do you have a reference or a link about the loop support on this phone? Thanks!

Just would like to say that it's not fair to say him that in case that the second entry said: One post on xda and he wants to root!
I think the problem is the order you gave him @ante0 (MAYBE!)
Unlock bootloader
flash TWRP
And I think he now has a BIG problem bc you DIDN'T said or forced him to go into developer settings and turn on OEM-unlock!
@nawraz did you turned on OEM-unlock in developer settings?
if you boot into fastboot mode are BOTH (bootloader and FRP = unlocked (in red letters), or and I really hoper NOT is FRP lock (in green letters)???
Maybe that is now the problem for him, not being able to flash SuperSU?
If you have luck @nawraz then try to flash TWRP 3.0.2-2 and with that SuperSU2.79
If you have root then you can install latest TWRP (3.1.0-1)
If you can't flash anything... oh oh!

He already unlocked and flashed twrp.
3.1.0 installs SuperSU fine. 3.0.3 does not.
And if oem was locked he wouldn't even be in twrp as you can't flash anything with fastboot if it is locked.
But I'll update my post in case anyone does miss to unlock oem.
Hope you don't get me wrong!
Just said that bc I had that problem 5 days ago and the only thing that helped was funky!
I had a softbrick and a reboot always kicked me into eRecovery
I just had eRecovery and fastboot!
Bootloader relocked and frp locked!
Stupid me relocked the bootloader bc I read that you then can unlock oem, then unlock bootloader again!
Well, that was a mistake!

Yeah. Only way then would be to rebrand to C636 using the DLOAD method, then rebrand back to your stock version using the Update thread under Guides. The latter requires twrp though so you'd need to rebrand first to get a working system.
To be honest I just figured he had already unlocked and flashed twrp as he was in the decrypt thread
Missing oem was an error on my side. It was long since I had to unlock oem xD

Weird. I tested with 3.1.0 a few days ago. But I guess it could have to do with builds. 3.1.0 is using kernel for B182. Maybe it's fixed if you use 3.1.0 with B182.
Oh well, good you managed to install it anyway.
Edit: I tested with the SuperSU I linked.

All I know is that it wasn't present in builds before B182.
 @st_voss is the one who found out it was added in B182 (Kernel build April. 11th probably as that's what I have on B182.).
It might be present in B181 on C636 as well, that was released 8th of May.

Boot animation problem

Hi
since i flash my update rom android 7.0
i have two Boot Animation
first is for honor
second is huawei
how remove second one?
plz help me
Try to clean flash your firmware through dload method, trying to be accurate while flashing. Something surely went bad while flashing the update you're talking about. Maybe you flashed the 7.0 for another variant, and now it messed up the firmware. Go on hwmt.ru site -> firmware database, and recover your ROM update package.
You have to pay attention and flash ONLY packages that matches your build number first 9 characters. Like "BLN-L21C432Bxxx", for example, will work only on a BLN-L21C432Bxxx. Flash only packages with PV at the end of the name.

What command you use. You have Android 7 or 8 right now
Android 7.0 I have been using that app. That boots it into recovery then tries to flash it. I tried to get the adb cmd to work but it doesn't find the file. I know this all sounds like gibberish but that's why I'm lost.

How to unbrick you NOKIA 6 TA-1021 and 1033.

This works only if you have working Fastboot AKA Download mode and you have unlocked your bootloader .
First download this --> https://github.com/StollD/NOST/releases/download/v0.6/NOST-v0.6.exe
Its a latest one and the working one. If you have LOST LA installed just unistall it. That doesnt work at all.
Then you need to download this FIRMWARE --> https://drive.google.com/uc?id=1smpap8mB0RZNk1j_HD0IJUX5LjFzKC4a&export=download
Then istall NOST and extract ZIP file. Launch NOST and select next. Make sure you phone is connect to your pc and it is fastboot mode "download mode" and find your phone. If it does then just click next. Now select the extracted nb0 file and go next.
If i remember right there is normal and rescue install method and some other too. I use the normal method. Then just go and start the install. Every first time it do something to my phone but give me the error and did not pass the install. But when i try it again it works just fine and finish the install. Then your phone should just do a reboot and voila, you have a stock nokia firmware installed succesfull.
After i do that, and my Nokia 6 1021 start, its download first PIE version and installed. After that i can do OTA install the latest PIE version. And i still can have my fastboot a live. So if you have like i have unlocked bootloader you can flash the latest TWRP and latest stable MAGISK 19. Then you have a working ROOT your phone
I just use "fastboot flash recovery recovery.img". Then "FASTBOOT REBOOT" and straight push volume up and power button together so long that your phone go twrp. If you fail its install stock recovery back. You can try again. I Try couple of time and i get it
Now my phone have latest PIE and latest MAGISK.
You need an unlocked bootloader for that.

If everything goes well yes but if it doesn't boot (as I had when I had unlock the bootloader), it won't be able to use NOST because you need an unlocked bootloader to use it and flash the nb0

NOST refuses to flash your phone if your bootloader isn't unlocked critically. The old OST would just try to flash but never make any progress which confuses inexperienced users.

Thanks man, I edited.
My phone is hard bricked.
Recently I was continuously charging my phone with power bank. One night I forgot to put my phone on charge and it got discharged fully. I tried starting it in morning but it got stucked at Nokia logo, I tried getting it into recovery mode to reset it but was not able to because i haven't connected it to power before. Afterwards I connected it to my laptop whose charger was having earthing problem and giving shocks. In between trying to put my phone into recovery mode along with connected to laptop, the current passed through my phone for 2 times. And that was the last moment i had seen my phone's screen lighted, and then full blackout.
I have taken it to service center first, the person tried installing the software on phone again and confirmed phone is being detected by PC but unable to install software. They had given only one option to change the motherboard to fix it.
Then i tried getting it repaired at local shops, where a person told me internal memory IC has been shorted. Another person at different shop tried repairing it and was also not able to fix and said lastly that motherboard is dead.
I think maybe Hardware kernel got disturbed, so is there any method to install the hardware kernel again?
have you Nokia 6 TA-1033 SS firmware rom download link?
Links are dead

Having issues decrypting after attempting to do OTA update

Hi,
My phone is rooted and with twrp. After attempting to perform OTA update, it now boots straight to the fastboot screen. I still can get TWRP to work but there is no prompt to decrypt my phone after twrp starts so I basically can't read the phone contents. Much appreciated if anybody here can guide me to fix my phone. Does it mean I will lose all my data?
Thank you!
