P9 can't run TWRP

Hi all
Got a P9 EVA-L09 (B378) EMUI 5.0 Andriod 7.0 Noguat , Bootloader unlocked
Downloaded the ROOT_P9 rar package that you can find nearly everywhere on internet, and after rebooting and placing in recovery mode (start / volume up) wont start the custom recovery.
Did you try TWRP for N: https://forum.xda-developers.com/p9/how-to/twrp-3-0-2-0-n-t3506947
Done worked, but i erased the OS for error , reinstalled a new one but it's buggy, no keyboard no bluetooth; now i have a C900B300

[HELP][SOLVED] Bricked my P8 Lite 2017

i need help to unbrick my p8 lite 2017,
to start my phone was with "cust c555 pra-lx1 emui 5.0.1"
my initial idea was to debrand the phone, but all the guides I tried failed, always returning to the original ROM stock,
then i backup my oem info image, custom.bin and build.prop...
then I wanted to change the method, trying to install oreo emui 8.x, with this guide: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
but result was failed, (I only have a doubt, when I was downloading the zip file hueuupdater via twrp I was doing it from the elite twrp and not from the twrp nochek oreo.....)
* last attempt was flashed via elite twrp an oem info file img (of a fw base nougat nobrand, corrected for my model pra-lx1)
after having opened the file oem, the problems have started, the phone does not go in fastboot mode, it does not go into e / or twrp recovery, it turns on and always restarts, I tried to flash a fw using the dload method but it does not work, I tried to reinstall the fw via erecovery using the wifi but does not start, always error .". Getting Package Info Failed"
now I really need help to restart the phone, someone is kind enough to help me or suggest a proper guide, to unbrick my phone?
thank you
i solved with correct oem info eu!!
Try Firmware finder for huawei + erecovery method , which is :
- download firmware finder on *another android phone* and search for exact phone model (ex : PRA-LA1C185)
- choose the very first firmware down the list
- Get an update thorugh dns >> Manually >> Register update
- After that , reboot your bricked phone into erecovery by ( power + volume*+*)
- press download recovery and last firmware
- wait till getting package
- by now should firmware start downloading
- let phone complete it's work and reboot
Hope that's work for you ?

Type password to decrypt storage

Hi, I have a P9 lite and I am trying to get rid of some crappy vodafone ROM on it.
I have unlocked the bootloader but now after many attempts to install various ROMs I am stuck with this message.
It will stop at '5% installing' if I try to install any ROM via SD card, say installation failed and then return to this message.
What can I do to resolve this now please?
Thanks
When you are adding new fingerprint you must add pin or password protection. The password to decrypt storage is the pin or password from fingerprint protection. After that you would be able to install rom.
1. Dload method to rollback to Marshallow (small and big package).
2. Download official rom with OTA and update to Nuogat
3. Unlock bootloader, reboot phone, skip all configuration (the most important! DON'T ADD FINGERPRING AND PIN).
4. Reboot again in bootloader and install TWRP (I think, your phone support TWRP). If you would like to use official rom, that's the end. If not, go to 5.
5. Install ROM (EliteRom 7.7 for example - READ THE INSTRUCTION).

P8 lite 2017 hard brick unfixable ?

Hello, I've recently installed TWRP on my PRA-LX1, i made a backup of all partitions in case everything goes wrong... and everything went wrong ! I tried to install a custom rom so i formatted all partitions except internal storage, boot, cust and version (all unformattable partitions) . The installation of the custom rom failed so i planned to restore my backup then i realized they've been deleted. my data partition is now only 500MB instead of several gigabytes
Now i want to flash the stock firmware but i can't.
I tried:
- the sd card method but "software installation failed" after a few seconds
- Download the lastest package from Huawei (ERecovery) but "getting package info failed"
- extract the firmware then flash it via fastboot but fastboot doesn't let me flash vendor and product images. twrp too (error:"cannot flash images to file system")
Now my phone is completely stuck
What i can do right now:
- boot into TWRP
- boot into Huawei ERecovery
- boot into fastboot
I think the situation can't get worse. At this point I'll do anything to get back the stock rom even if it's dangerous for the phone. If someone have a full twrp backup of the p8 lite 2017 PRA-LX1 on android 7, please share it
