Hi all!
I am looking at getting official TWRP support for the P9 (aka 'Eva') (as I have for the other Huawei / Honor devices.
After creating a basic build tree, I have been spending countless hours reversing the decryption routines from the stock recovery and the good news is - I have a RC build online ready to try, complete with /data decryption!
I will be submitting the files for official TWRP support shortly, but in the mean time you can check out the build below. Flash using 'fastboot flash recovery' and, of course, use at your own risk.
Enjoy!

Could you guide how to build twrp for mate8?
Sent from my NEXT using Tapatalk

i tried flashing the recovery but even after success the phone doesn't boot to twrp but to the huawei erecovery. any suggestions? my phone's model is EVA-L19
Finally tried the recovery posted here and it worked. http://forum.xda-developers.com/p9/how-to/guide-root-huawei-p9-t3367800

I know that TWRP can't read /data, but can it wipe it? My phone no longer boots (more gory details at http://forum.xda-developers.com/p9/how-to/how-to-reset-phone-installing-twrp-t3378347) and I am wondering about the best way to do a factory reset.

You should be able to format I imagine.

Didn't work I think it's because it can't mount /data to format it. Now when I boot I get a message saying that encryption was not successful and it asks me to do a factory reset, but I don't know how to do that!

I would suggest flashing stock recovery, or doing a format on userdata I guess.

Problem solved! Just in case anyone else ends up making the same silly mistakes as me...
Formatting userdata doesn't seem to work; this seems to be a common problem on Huawei devices.
Code:
> fastboot format userdata
FAILED (remote: Command not allowed)
But flashing the stock recovery (I used the recovery found in the SRK tool from http://forum.xda-developers.com/p9/development/tool-srk-tool-huawei-bootloader-root-t3374068) did work.
Thanks for all your help!

@paulobrien any news for data decryption?

And you try to format data ? Not factory reset ? Format . it must work . it works for any other phones with Android 6 . but then you will need to flash custom ROM .

@paulobrien after upgrading to L19C185B138, this recovery is working. It is now asking for password, which i believe is to decrypt the data partition.

Decryption reverse engineered, coming soon!

Tested and working..although backup seems to failed..it says system backup failed error 255

Fails on data partition backup to external sd card (internal memory backup fine)
Same 255 error as above

Maybe because of size ? More then 4 gigs ?

Did you solve the problem yet? you may try to delete TWRP folder in your internal and external storages they will reboot twrp and required your permission to write again when you go to recovery mode next time. and it will be flashable (as my experience)

Nope, im talking about while running the system, it works fine in twrp, i actually solved this by changing the permissions by checking all the boxes with es file explorer.

Failed to mount 'system_root' (Read-only file system)

I think I bricked my Poco F2 Pro (Redmi K30 Pro). I installed LuckyPatcher to disable disable signature verification. When I LuckyPatcher rebooted, I got stuck in a bootloop (the phone booted to Fastboot instead of System). I now want to format data in my TWRP to flash a new ROM and start from scratch. However, when I format data I get the following error in my TWRP: Failed to mount 'system_root' (Read-only file system).
I tried unsuccessfully tried fixing it by starting Terminal in TWRP and typing "mount -o rw,remount /system". I get "mount: can't find /system in /etc/fstab. with "mount -s system", I get a bunch of text but nothing that makes sense to me.
I hope somebody can help me out here...I just bought it :crying:

I had this problem a few days ago. To solve it, I had to reflash the rom (without formatting any partition) from twrp, ignoring the errors. (I'm on xiaomi.eu stable rom)
The important thing is to never modify the system partition (via lucky patcher or other tool) after installing Magisk, otherwise the phone won't reboot.

Look the picture, I reflashed the rom with twrp. I still get the error cannot mount.
I see that some people have solved it by external rom installation, using adb sideload? How do I do that?

Not enough DIY.
Take a look at this:
https://forum.xda-developers.com/t/twrp-xiaomi-12.4470519/post-88080799

so if any errors occur, provide recovery.log right after the error
Code:
adb pull /tmp/recovery.log

For this error it seems pretty clear to me, damaged partition, root, modules.

yes, most likely corrupt file system. my guess is unreadable file. recovery.log will tell file name failed.

You don't have to modify the system, just format the data type yes, reboot Twrp and try, if that's not enough, flash a stock rom with Miflash then the latest Twrp and try.
