Hi someone, i hope...
Recently i do a bad upgrade (I think that i flashed recovery on boot, ups!) and after a long, long while i have the phone working again But....
I can't change rom!!!!
Now i have:
- B609 boot unlocked
- B609 stock recovery
- B609 (Flashed through CWM, the only way i can do it)
But i can't change rom, not by dload, neither twrp, neither cwm
Some help? Any idea?
I can flash every recovery and i have tried to roolback b133, update b620 and even b805, but it doesnt work
Can i try another solution?
Thanks in advance!
I'm having the same issue, neither the original stock rom with emui 2.3 or any 3.0 rom install on my p7, all roms ends with an error and after booting there's some apps missing
EDIT: I've followed the only two guides on this forum and still can't install stock rom emui 2.3
So no way to downgrade from b805???
Hey guys... Look @ my edited answer here:
http://forum.xda-developers.com/showthread.php?p=60766165
I'll try! Thanks!
Tonight i've discovered another issue... :-/
When i switch off the phone and connect usb for charging, the phone switchs on, no charging screen, it boots
I think your phone is "dirty". I dont know the right word in english. Try my solution and be happy
Ohhhh! No luck! It gives me the same error, install failed
I've tried to erase the partitions with fastboot and it says: Command nos allowed, i think' perhaps i have security on, but i dont know how to s-off this terminal
I've entered in engineering mode and i can see: fastboot P7-L10C900B805 while i am in b609 (b805 was installed before the fail) so i have to try to downgrade fastboot. Unfortunately it cannot be done with fastboot, again "Command not allowed" :-S
Try to make a install via fastboot with all partions. I think you can try it with b609. If that not work - i have no idea ! I think that you have to wait for full b805, install that via dload and then you can downgrade. The same issue i have with b609 @ beginn
Flash MyROM 3.3, then flash a 3.0 stock recovery. Now do a normal update to the full b609 using the dload folder. Use thw update feature from the settings menu, and not the 3 button method. From here you can do the same for b621 and then b805.
Hope that helps.

I think thats help
No way

I'm going to try this method too, wish me luck
Hi all, i've been trying to fix this for 2 days and still failed to get it working.
I regret that i quickly jump into the nougat build and would like to get back to stock rom for now.
I tried downloading all the ROMs at stock rom thread and keep on encountering error when update reached 51% with software package/update failed error message.
I'm using P9-L19 and hopefully can revert back to C636 roms.
Thanks.:crying:
have you try this?

As someone new to this, this seems kinda complicated.
I'll give it a try. Just have to follow the instruction in the video?
Download the stock rom to external memory card in dload folder and use this code in phone dialer
*#*#2846579#*#*
And select update system
Flash update in dload don't work
Please help
Is your bootloader unlocked? Do you have a twrp backup?
I don't know if that's a good idea, but you could wipe system partition in twrp then flash stock recovery and try stock rom again? Going by the assumption that your current system is causing the update to fail.
Maybe nougat beta has a new recovery that won't flash old firmware? So maybe try an old recovery?
I'm just brainstorming though, no idea if any of this works. So try at your own risk.

Hello, my P9 is 100% origin.
I managed to use an OTG cable and put the firmware (update.app) on a flash drive under the dload folder. then powered the phone off and pressed both the volume keys + power and the flashing started
you need to download full stock rom the same version as you have before upgrade to N. then try to flash via project menu (*#*#2846579#*#*)
if this method doesn't work you may need to goto recovery menu and wipe data/factory reset. then you might lost all your theme and system apps.
but you will be back to to stable stock rom. if you need to use theme and need the stock system app again to have to Root your device. and install data/hw_init via SRKTool
Hope this help.

After wipe data you need to dload stock rom again though

First unlock your bootloader - then use Huawei Update extractor to extract ( I suggest the C636B168 Rom) from the Update.App the recovery.img - after flash from an adb folder the recovery.img through fastboot - use the three button to install the Rom and you're ready.
Warning.. everything in your internal storage will be erased so make a backup first.

Download stock firmware and flash it via dload method.
i dont know exactly how to do it. Do i just create dload folder on sd card, put the rom in it, then turn off the device, pres volume + and - and power button? or do i have to do even something else?
And where can i download Stock ROM? I downloaded some but i dont know if it is legit, official ROM

Only firmware which will flash via dload..should be same number or higher number...
For example if you were on b340 you can only flash b340 or higher number like b341 or 350
You cannot flash 330 without rollback pkg

Before flashing new rom wipe all partitions from twrp.

I'd suggest HurUpdater: https://forum.xda-developers.com/ho...h-official-firmware-recovery-t3769279/page111
OTAs do work with an unlocked bootloader, but not with root or custom kernels.
Does this works with the P10? In the post i ddin´t found the P10.
And if it works, wich zip file i have to choose? And i have root
Thanks
Try my guide (Tutorial #2, Oreo to Oreo)
After that do a factory reset with eRecovery (boot with Vol+ and connected USB).
What also should work is flashing the system.img manually via fastboot.
For this extract the system.img from the correct firmware version with Huawei Update Extractor.
Connect your phone to your PC, boot into fastboot and flash with "fastboot flash system PATH\TO\SYSTEM.IMG".
After that do a factory reset with eRecovery (boot with Vol+ and connected USB).
Note for the next time: backup your system partition via TWRP before flashing the custom rom.
Also note that a factory reset is needed, without your phone won't boot, so backup your personal data before doing it.

Yes, it works on the P10. You can download the files with the firmware finder app. I'd recommend the newest oreo version for your customisation (e.g. B382 for C432).
But Jannomag's solution should work equally well.

Possibly you renamed the wrong customisation file (i did it once for the 09 while I needed the 29).
Which one did you download? And did you flash manually or did you use my script?
Download my oeminfo, it's from VTR-L29C432 Version 8.0.0.380, while the version doesn't really matter.
Flash it via TWRP using "Install" and "Use Image". Flash it to oeminfo partition. Then do my update script again.
I followed the guide to do Oreo to Oreo - basically wanting to get from custom Rom (fRomFuture B370) back to stock, so I chose the same firmware version to extract. Flashed everything with the script and it went fine and it boots and works.. but
The resolution seems to be off, too low and the right side of the screen is unresponsive to touch (about 1cm )
EDIT- Rolled back to fRomFuture B370 for now - need to find a way to get back to stock, as want to move on to Openkirin ROM instead
HI, i have a vtr-l29 root, i want to unroot(version oreo), how do i do it? what do i need to flash?. thank you Alex
