[Q] Update with open bootloader and TWRP

Hi!
Soon we can expect some update to P9. Can I update in the future through OTA with open bootloader and root?

Yes, just flash stock recovery, make update and flash twrp back.

Thanks, where can we find original recovery? any idea?

you can flash it with the SRK Tool: http://forum.xda-developers.com/p9/development/tool-srk-tool-huawei-bootloader-root-t3374068
Edit: stock recovery also included in this pack: http://forum.xda-developers.com/p9/how-to/guide-root-huawei-p9-t3367800

Extra info, i have updated today:
Once you have flashed back original recovery you can begin update. But it is going to fail. Your phone first downloading a small update package (mine was 175mb) but since there were some changes due to root it failed immediately. You phone restarts and is downloading the full update package (~1.7gb). That is going to be OK.
You have to reflash TWRP and reflash root zip in order to have root.

so no issues with xposed when upgrading?

I have the custom one from Wanam that keeps the huawei theming engine intact. Is that systemless?

Yes. It is systemless. If you have both systemless root (SuperSU 2.62 and after) and systemless xposed, update should not be an issue.

I flashed stock recovery, update failed. now i can't download the update again. (rooted with supersu v2.76 and xposed by wanam)

hi

any idea
edit: same problem after restoring backup twrp no ota available
Edit2: i should restore p9 with dload b136 ( full wipe and relock bootloader ) and after made the ota update and restore backup

so it worked for you after resetting the phone? The status of your bootloader should have no impact on OTA from what I've seen.

Hi when you reflash with the firmware b136 by dload the phone do itself a full wipe and relock the boot loader
After the ota b166 was made fine

thx, at least there is a way not prepared to go through all that though. I just realized I still have the update files on my phone (under \Internal storage\HwOUC\54265), there are two files: update.zip (381 mb) and update_data_hw_eu.zip (84 mb).
All I have to do is start up the update process again, as the files are still there. I tried moving these to dload folder on the sd card, packed, unpacked etc nothing seems to make it work so far. If I copy just the update.app from inside the update.zip the update process works but nothing changes, still on B136.

Yeah, holding back here for the moment, until we have a clear idea on how to update. I'm not needing b166 that much, that I have to jump through all those hoops, reset, wipe etc. just for the update.

How can i flash the stock recovery, tryed with STK Tool got an failed . (Command not allowed)
Ok, Recovery should now installed, but, when i press all 3 Buttons i got EMUI "Download latest version and recovery" "Reboot" and "Shutdown" When i click Download.... he cant download any files, wifi is working!
But it didnt install the Update.APP from the dload Folder. (B166)
I am at the Moment on B136

Not exactly understanding what you are asking. For some reason moving the update.app from B166 in the dload folder is not working for this update. So at this moment there is no way to manually update.
If your OTA update failed and/or you don't get the update notification anymore there is only one way to get B166 at the moment: Flash full stock B136 (dload method), which does a factory reset and reverts everything back to stock, then you will get the update notification back and the update will work, even with unlocked bootloader.

I tried to install B162, that doesn't work with dload. My Bootloader is still unlocked, stock recovery is now installed, still rooted.
Should I try to install b136 and try to get the update?

I need L19C432B136, have someone an link for me, cant find this ROM

[INTERESTING] Updating system while rooted

Alright.. Although this is worked on me last updates (B190 to B550 to B560 to B564 to B574) I DON'T PROMISE IT WILL WORK ON YOU!
as always, it is possible that you brick your device, break your sd card, your phone catches on fire, you start WWIII SO KEEP THOSE ON MIND
But.. for me when new update comes i just install it by doing normal force update but i press all three keys as long until i feel second vibrate.
This method is worked on me all those updates i wrote first AND I WERE INSTALLED TWRP AND ROOTED all the time.
When you install update by this method. You lose TWRP, Root access and all what you have flashed by TWRP.
EDIT: UPDATED ONLY USING FULL ROM!

So you don't need to install even stock recovery first?

For me it has worked great without stock recovery. I have always installed full rom so it installs stock recovery

So interesting!I'll try it.But it dosen't work for my honor 4C.

Has anyone tried going from Sokkoban's deodexed ROM (B564) to B574?

It seems like there are 2 recoveries or something. I have TWRP installed and once i held power + vol up wanting to enter TWRP, but it seems like i held it for too long and the phone booted into the stock recovery and in the top left corner it said "Huawei eRecovery"
Strange...

Yes if you extract firmware you see recovery.img and recovery1.img.

Hi everybody, I tried to google it and search XDA so far, but am not quite sure.
I have ALE-L21C432B170 installed on my phone and downloaded the official update.app (ALE-L21C432B550) for Android 6.0.
So it should all be fine.
My phone is rooted + TWRP recovery but with Stock Rom, so no major changes at all regarding the OS.
Did I understand it correct that the update (using the running system or forced update) will work with my phone?
I am sorry if this was answered before, but it still remains unclear to me.
Thanks, Chris

Hi Chris! For me, it worked while i updated from B190 to B550 so it should work from B170 too!
But i recommend you to download some newer version like B560 or B564 (No double tap bug)
Edit: and do force update
YOU WILL LOSE YOUR DATA SO BACKUP, BACKUP!

Hi Vika, thanks so far. I do backup regularly and especially before doing stuff like this... just wasn´t sure about user experience. I´ll consider trying. Otherwise, I will go back to standard ROM, update, and root & TWRP again.
Might take some time, but I´ll let you guys know.
Thx, Chris

It doesn't work, any ideas?

Huawei uses two recoveries yes
One stock recovery for updates and such hence recovery (1)
The other one is the "emergency" recovery which is EMUI recovery to download a firmware which usually fails anyway (maybe due to unlocked bootloader and removed drm?)
Also yes it's possible to install OTA due to the fact that TWRP uses a legacy script when it's installing OTA's which is used in regular recovery, therefor it won't fail this has been announced in TWRP changelog but few is understanding it.
Only downside is it will revert recovery and kill root.
and small updates will install just fine, doesn't matter which, just be aware if it mess up its not anyone else fault but yours if you update and it suddenly dies or bootloop

I confirme it works like a sharm

Need help to downgrade from Nougat to Stock Rom

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:

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
What is your build number before goto 7.0?

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.

i installed the huawei p 9 nougat version and i wanted to downgrade but nothing seems to work. I have got unlocked bootloader and when i had emui 4.1 my phone was rooted and i had twrp. But now i can´t boot into twrp. How can i downgrade ?

solved! Bricked/ wiped my P9

Hi.
A while ago I installed lineage 14 on my p9 because my son who uses the phone did want to have an experience a little closer to aosp.
Today he wanted to go back to stock emui. I thought I use the dload method. But I couldn't enter the recovery. Every time I ended up back at twrp.
Then I installed magic rainbow 4. The installation went OK but not all apps where available. Camera etc not installed.
Again I tried to use de dload method but still the same issue.
The I tried to reinstall lineage 14. Because in magic rainbow I couldn't enter the the developers option to activate oem unlock or USB debugging.
I thought that the problem for dload was an frp lock. In bootloader there is everything unlocked. But I wanted to check it.
After reinstall of lineage I wanted to reboot but I always ended up in TWRP....
I seems that there wasn't a system installed?
Then I found a tutorial that said to wipe all partitions and manually flash boot.img and system.img
But the flashing failed of both img.
So now I have a phone with all wiped....
Anyone an idea about this?

You had to use the proper TWRP (from MR v4 thread) and flash by HWOTA the same stock you were before going to custom.
You can try HWOTA7

or even HuRUpdater

And tried this also. Software installation failed.

I tried to install magic rainbow 4 again and it worked!
First I flashed TWRP from the MR4 topic.
But...
still various apps are missing. When I want to enter developer settings I automatically go back to home screen.
What can I do from there.
@Tecalote I'm gonna quote you here. Maybe you have an idea?

FYI
I managed to solve the problem!
Started over again.
In TWRP full wiped.
Tried HuRUpdater again. Flashed successfully the latest stock EMUi (C432-B505).
Factory reset in stock recovery.
Complete setup.
Rooted with latest Magisk (patched boot.img)

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
