P9 Bricked - Boot loop please help

Hi all,
I am facing severe problems with my P9.
Initial Situation:
Started with a brand new P9 with T-Mobile cust Firmware C150
What I did:
I unlocked bootloader successfully and rooted the phone. Then changed OEM info from C150 to C432. So far so good.
After that P9 booted into factory restore and restored itself into C900 Firmware. Bootloader was locked after that.
I unlocked bootloader successfully for a 2nd time.
Current Situation:
Now when I boot the phone it says: "Your device has been unlocked and can't be trusted" .... Your device is booting now... => But it never boots into OS. It stucks here forever.
When I press vol up and down and power for some seconds I can at least access TWRP. When I try to reboot in TRWP it says "No OS Installed".
But how can I do a stock recovery or install a working Android OS in order to get the P9 into normal boot Modus again?
Please help me.
Solution summary:
Issue solved by using the dload method to change to C432B182:

If u have a sd card u can put it in another phone if u have and create a dlod folder, put the Firmware u need in it and then switch it to your P9 and try to upgrade. Since your phone is C900 i think something went wrong in the debranding so use a full stock C150 firmware or try with this B136 Firmware with dt and hw folder toghether with update.app in dload folder.

Sent from my VIE-L29 using XDA Labs
@panosm763: Thx for the Video link. I worked according to the same but after changing OEM info phone booted with red warning Screen and installed a fresh C900 Firmware Version. Then after opening bootloader again, SRK Tool cannot connect to the phone anymore maybe due to the fact that usb Debugging mode is not turned on (and cannot be turned on because OS is not reachable)
@Mostar088: I tried the dload method yesterday with the Firmware from the link you shared. Unfortunately without success. The phone did not recognize the Firmware and did not load the same. Maybe because bootloader is still open? I have no clue why this method is not working
Issue was solved.
It worked out fine using the dload method described in here:
http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818/page1
I am now on C432B182 :good:

P9 EVA-L09 problem with software

Hi, I've got a problem with booting and generally doing anything on my phone - only erecovery is working right now. I've tried to install 7.0 update - and it got the NRD90M rom instead of b361 or b360 - then I've tried to do an update via dload - however, it failed - I read somewhere to flash extracted files like system, recovery (and sth else) via adb - i did it and now i've got nothing. Are there any posibilities to get my phone back? to install software? I've tried to install twrp but it also failed - i mean i can use adb in erecovery mode but i can't turn twrp on - 'device is booting'... Any ideas? (Sorry for my english)

VIE-L09 Can't get out of eRecovery

Hi guys I have a problem. I tried to upgrade my p9 plus manually with an ota update.
I had VIE-L09ITAC555B130 and I tried to install VIE-L09ITAC555B360 to get emui 5.0. The updater wasn't able to complete the download so I tried manually. B360 is split in two files (I don't know why, this is my first Huawei), I tried the first but at 30/40% I got an error, then I tried the second update.app and now my phone boot in eRecovery mode.
I can also boot in fastboot mode but my bootloader is locked and I can't get the product ID.
I also tried to install B130 again but it didn't complete the process. I don't know what to do anymore, some suggestion?
Sorry if my english is pretty bad...

Softbrick P9 Plus

Hello folks,
so a friend of mine is a complete noob and have this problem with his p9 plus.
The phone keeps rebooting itself in an endless loop, i can't access recovery and only when plugged in to the PC i can access fast-boot.
Phone is locked, FRP Lock.
With getvar command i managed to get this info:
rescue_phoneinfo: VIE-L09C113B170
seems that there is no full zip of this rom anywhere just partial ota (found those with firmware finder) but even with that when i try to flash recovery i get command not allowed.
On the fastboot screen of the phone i have this reboot reason AP_S_PANIC
anyone knows a how to get the phone out of this? (i was thinking that maybe unlocking the bootloader could be of any use, but in the request page it's needed the Product_ID and i don't have it. (can't *#*#1357946#*#*)
I don't know if it does work in a locked bootloader.
I have my P9+ for a week and maybe if you download a firmware compatible with your version and try to 'hard' update the phone, using a SD card with a update file on a dload folder and restarting the phone pressing VolUp + VolDown +Pwr, you can restore your friend's phone.
I'm sorry if I didn't help, I am myself stucked trying to rollback my version to MM and have the NFC and the Bluetooth working again...
myself also got this problem..please anyone..

When I go to the eRecovery and try to Download Latest Version And Recovery it gave me an error that says Getting Package Info Failed

hello!!
I think your guide will save me because I am in that bricked condition, BUT I can't put my P8 Lite 2017 in eRecovery mode.
The phone stuck in Huawei Logo, static logo.
If I keep pressed Power button it shutdown and then restart immediatly
If I keep pressed Power button and a second before it start I press Down button and put usb cable I can enter into fastboot mode.
That's the only mode I can enter, but as I wrote on my post some day ago, I got Phone and also FRP locked.

Sorry for the late reply
Try to press these buttons Power+VolUP+VolDown while booting the device
It should try to find a frimware to install but it will fail and then you choose Reboot Device

You have to do each step carefully it gives you an error cause you didn't change the DNS settings on your Router
BTW don't connect your phone to WIFI until you set the DNS settings after that Restart your phone and Download the Frimware

To revert back to Huawei GR3 2017 you need to flash the OEMINFO of PRA-LA1C185 first then follow my instructions

BTW I don't know if you're asking a question or not? (No Offense )

how did u brick ur phone? wut stuff did u install and do? just curious because i havent brick my device and im doubtful/weary of the honor 8 lite firmwares/oeminfo that they might brick my pra-lx1.
- i unlocked Bootloader
- flashed TWRP- 3.1.1
- i flashed Oeminfo PRA-LX1C432.zip via TWRP
- phone reboot and it goes to Factory reset and stuck at 99%
- Bootloader and FRP locked ( i don`t have any Google accout aktiv)
- erase FRP via DC Unlocker
- enter erecovery and download latest Firmware
- download finished, installisation chrashed approx. at 80%
- since that Phone dead, no light, no screen
only thing, when it connect to PC it detect Phone in fastboot

is that the twrp 3.1.1, the one that have the additional options (oeminfo, vendor, cust, recovery....) for Install?
if phone can still be detected via fastboot, i think there is still hope for that...
were u trying to update/downgrade from Nougat to Oreo or Oreo to Nougat??
have u tried booting to twrp recovery?
so u have an unlocked bootloader and an unlocked frp
have you tried extracting "boot.img, recovery.img and system.img" using Huawei Update Extractor v0.9.9.5 from your downloaded stock firmware's "update.app" by firmware finder?
* boot.img - kernel files
* recovery.img - recovery
* system.img - rom
then flashing them by these commands?
Code:
fastboot flash boot boot.img
Code:
fastboot flash recovery recovery.img
Code:
fastboot flash system system.img
then
Code:
fastboot reboot
this method is just by pure research, idk if it will work or the success of it. but you can try at your own risk though..

HI, after a disaster I experienced installing the beta treble emui 8 when I stuck in a rom without possibility of updating, and after I tried to go back by an update.App and a dload trick I find my self stuck in emui 5 and Android 7 but in a test rom without possibility tu update...... Your "trick" tutorial is a salvation, thank you mate.
regards
you cant use this method when you cant boot the device from my experience i relocked the bootloader after restoring twrp backup(so stupid of me) i need to send it to authorized service center if your warranty is still valid its free of charge or you can just tell them that u updated your phone and that happened they might even replace it and for me they replaced the device.this is the only way i think i can help because u cant flash anything when frp is locked.
I always get "Getting package info failed" error
still "Getting package info failed" error :/
cannot recovery also via dload/UPDATE.APP (with a small 8GB-sd in fat32 and/or in ntfs, just for test all circumstances), and tested with many different firmware (from very old nougat release, to latest oreo - mine atm installed, but bricked after magisk installation)!
still continue with same error via erecovery, and with 5% hangs (and reboot before more minutes) via dload.
Please make a video tutorial
