Messed up P9 - Huawei P9 Questions & Answers

My P9(L19 - C636) is really messed up right now. I messed up my firmware. My phone has its bootloader unlocked, rooted.
It has C900 B168 install. I just want to go back to stock with locked bootloader. Please help.
PS:When I boot my screen is like this instead of the huawei logo: https://imgur.com/a/s5mRH

ALSO quick note when i attempted to flash oeminfo on twrp, it kept saying unable to mount /data.

I think its messed up yes.
You can try to use the Rollback Package in my description, its for L09 and L19 after this u should try to dload something like this firmware:

Help DBranding Huawei P9 Plus

Hi Guys,
I need serious help, as I tried to drand my Huawei P9 Plus, that I have purchased for UK Vodafone in the UK, as they are the only people who sell it.
This phone was originally on VIE-L09C02B131.
I have tried to dbrand it to L09C423B181, using the video guide [VDO-GUIDE] How to debrand Huawei Phone by SRK Tool Huawei by somboons. It is now showing as L09C900B181.
I tried again to unlock my bootloader, Install TWRP, root my phone, so that I could reapply the correct C432 oeminfo and custom.bin file.
However my phone is now stuck in Huawei eRecovery boot and I am unable to get back into my phone at all.
Can someone please help.
UPDATE 1: I have now managed to get L09C432B181 installed on my phone, however, the firmware is still showing as L09C900B181 and my theme are now showing default.
UPDATE 2: I have now installed TWRP and SUPERSU, however the phone keeps rebooting to Huawei eRecovery. I now need to now update the custom.bin and oeminfo to C432.
Someone please help me. I can't work out where I went wrong, as I have followed the dbranding video.
Thanks in advance,
Bashy

Q:p9 plus debranding.

now i know why everytime i manual update my p9 plus c636b103 to higher firmware is making it c900. its because my p9 plus is locked to its network carrier and the network smart is not releasing the ota for p9 plus. i have a vendor of smart country ph.,
pls bare to read as your knowledge/experience will help alot not only to me but to the future whom might get the same questions as mine. pls answer every questions./problems i have encountered thank you.
Q:#1 as i understand i think i need to do the debranding?? to unlock my p9 plus from my network, at first it made me so confused because my sim is unlocked i can use any sim. but then i realized its still locked in system updates from smart ph.
Q:#2 do i need to unlock bootloader install twrp and root the p9 plus first before contiunuing to the vdo of debranding?
Problem: #1, i dont fully understand the vdo of droidth in debranding the unit. i got lost of understanding in the changing of ro. build. id something like that. i tried to do the extracting the verlist but when i open the extracted verlist. img in notepad i only get random letters and symbols(ex. b&+g~), but in the video i should see vie/nxtc636b***. so i really got lost.
Problem: #2. i know i need the unlock code from huawei website.before i can unlock bootloader and i already get a code but the problem is i forgot to right it down as i only txted it to my number which i also use in my p9plus and i factory reset my p9 plus when i install back to c636b103 because if i dont factory reset after install b103 i got null imei, camera crashes, internal storage none. but after factory reset its ok.
so how am i gonna get a code again? is it still possible to get the code again? can someone pls put the link? thx.
thank you.
your reply will be much appreciated.
Yes, you need to debrand your phone and install the generic firmware for your region (for example, c432 firmwares for europe). In order to do this, you need unlocked bootloader and twrp. Root is optional, it depends on how you want to change the OEMinfo. For the unlock code I think you can ask it again to huawei in the same way you asked for it the First time. For problem#1, sorry but I have no idea what you are talking about because I didn't use that guide. Maybe try to root the phone and then edit the file directly on it with somethin like root explorer.

can i use any firmware in debranding? and should i first go back to b103? i have frimwares here b180 b190 b170 b130 b362.. all ar3 c636, what should i use? and can i do now the debranding process even if im still on c900b180?
Since you are on C900, I believe your cust is broken. Read here: https://www.google.it/amp/s/forum.xda-developers.com/p9/how-to/how-to-change-cust-c900-c432-t3392824/amp/ note: it's about p9, don't download or flash anything from there.
Now if you want you can try these steps:
1- unlock bootloader (if it's still locked)
2- install twrp
3- flash via twrp the attached file (ONLY if your phone is supposed to be L29-C636, which I believe it is)
4- install a C636 firmware with DLOAD metod
Now you should be on C636 firmware with a debranded phone.

[Q] LOCK BOOTLOADER on OREO (not relock)

Hello,
I was on B360 Oreo.
I unlocked bootloader, flashed TWRP, used MAGISK (16) to modify boot(ramdisk) partition, flashed it and got ROOT.
Then I flashed HYPER KERNEL.
Now i realised that custom kernel gives me nothing special in term of battery life (after 7 days) so i flashed back all stock partitions (BOOT, RECOVERY, KERNEL).
Now I am on stock, but with bootloader unlocked.
So i can get updates, but no ANDROID PAY.
The TASK is: How to lock bootloader. I mean LOCK not RELOCK.
ON nougat when i used the HWOTA to debrand my device the device was automatically locked after the change.
Now on HWOTA8 i flashed all three parts of the B360 full ota to get the bootloader locked, but still unlocked.
I think to erase and flash OEMINFO again, but i am afraid to brick the device by that.
Does anybody know how to make forced update that the bootloader will lock?
@Blackball maybe?
Actually the only way i discover to do this is, go Back to nougat, and the update vía firmware Finder vía proxy while you had your bootloader locked after rebranding again, Cheers brother
will try to update via firmware finder from b360 to b365 full firmware. Will see.
How this went for You?

Revert rebrand

Hey everyone,
So, a couple months back I rebranded my EVA-L09 to a VIE-AL10 through the rebrand tool.
A couple weeks back I wanted to revert back to EVA-L09 to go back to Magic Rainbow v4 or v3.
I failed in trying to rebrand it back and ended up where I am now, I have TWRP installed, I can do the dload methods to install whatever, but I can't for the life of me get any ROM or firmware to boot. It either doesn't go past the "Your device is not trusted" screen or it hangs at the boot animation.
Extra notes: Yes I was on Oreo when I tried to revert, I am currently not on Oreo as I tried to flash a Nougat VIE-AL10 firmware to attempt to get the phone to at least boot to a usable state for the time being, however now it's stuck on a boot animation.
Would appreciate any help,
Cheers.
Update:
I tried to follow this: https://forum.xda-developers.com/showpost.php?p=77161313&postcount=2
But as mentioned above the phone hangs on "Your device is booting now..." after HWOTA copies the Nougat firmware files.

EVA is P9, VIE is P9 Plus
Don't mix firmwares, you wll (no wonder if you really mixed), brick the phone
One procedure is for P9 = EVA (and this is P9 portal here):
rebranding from EVA L09/L19 to EVA AL00c00b535 and back
https://forum.xda-developers.com/p9-plus/development/rebrand-update-tool-hwota7-p9-plus-vie-t3843930
The other is for P9 Plus = VIE (different phone, eg bigger display)
rebranding from VIE L09/L29 to VIE AL00c00b535 and back

Be more specific, confirm
- Your phone is P9 or P9 Plus?
If P9, was it L09 (single SIM) or L19 (dual SIM)
- On exactly which Chinese Oreo have you been (cannot be VIE, you must well know what you exactly had and what you were flashing), was it EVA -AL00c00 or what and which build number bXX it was
- Did you go to some Open Kirin/AOSP custom ROM or stayed on that stock Chinese ROM?
You first had to come back to Chinese stock Oreo, not downgrading to Nougat directly from Open Kirin / AOSP
- Downgrading consists of several steps, HiSuite to go to Chinese Nougat and then HWOTA7 to rebrand to eg c432 Nougat.
Up to each step did you exactly do when you got stuck in Booting?
-More precisely, if you downgraded by HiSuite to AL10c00 Nougat, did it boot successfully (or were you here stuck at booting)?
If that step was successful, which (full build name and number) you were flashing by HWOTA7 to rebrand to from the Chinese Nougat?
-Have you tried to switch off and boot again?
Have you tried booting to Recovery and do Factory reset and Wipe Cache and Internal mem and then tried to teboot?

Sure,
EVA-L09 is a regular P9. Not a P9 Plus.
I never honestly checked which Oreo firmware I was on. I downloaded the VIE-AL10C00B535 (8.0.0.535) firmware and used that.
Yes, at one point I did go to the OpenKirin AOSP ROMs. However, I was able to do the volume + & - + Power to return to Nougat and then re-flash Oreo. After this I stayed on the EMUI 8.0 firmware.
I did not use HiSuite as it never worked for me. It would always just tell me to go to a service center.
I did not use HiSuite. When I returned to EMUI 5.0.1 from eRecovery (?) Restoring over WiFi on the actual phone it booted fine and I then upgraded again to the Oreo firmware.
Yes, I have tried rebooting.
Yes, I have tried a factory reset.
When I tried to revert from a VIE-AL10 rebrand, my phone ended up getting stuck between an AL10 and an EVA-L09. Meaning that I can use the EVA-L09 TWRP but not an EVA-L09 compatible firmware or ROM. I can only boot AL10 firmwares or ROMs however they hang at the boot animation.

In yout previous post:

Guide you cited is for rebranding European P9 EVA to Chinese P9 EVA-AL10c00b535 - see attached screenshots from the guide, observe it is everywhere EVA-AL10, not VIE-AL10
Once again, it must be EVA before rebranding and EVA after rebranding.
VIE is different phone (different hardware - bigger display), P9 Plus.
If you didn't care about difference between EVA and VIE, maybe you really downloaded and flashed AL10c00b535 for VIE (P9 Plus) to your EVA (P9)
----
>> Yes, at one point I did go to the OpenKirin AOSP ROMs. However, I was able to do the volume + & - + Power to return to Nougat
This is procedure to boot to Recovery (eRecovery if charging by USB), not to Nougat
----
Details are important, not just when writing posts but really when reading guides and flashing, otherwise bad things can happen ;(
So please, consider again, did you really flash VIE AL10 to your P9 (5,2 inch display)?
(Maybe it worked somehow for AL10b535 because packages for Chinese P9 = EVA and P9 Plus = VIE are similar, but now when returning to Nougat it stays on VIE and doesn't boot)

I honestly can't remember how I did it now, it's been a while, but it did go through successfully, and it was working fine after applying the patch.
But yeah, as of now all I can use is fastboot and TWRP. That's all. I've tried flashing EVA-L09 firmware, it doesn't boot. I've flashed AL10 firmware and it gets to a boot animation, but no further than that.

Boot to Fastboot:
- connect by USB to PC and boot by: press and keep pressing Vol-, then Pow
Ececute from the PC side and copy/paste back your results (is Bootloader still unlocked, what the phone thinks it is current model, cust, build number)
Code:
fastboot oem get-bootinfo
PAUSE
fastboot oem get-product-model
PAUSE
fastboot getvar vendorcountry
PAUSE
fastboot oem get-build-number
PAUSE
fastboot oem oeminforead-SYSTEM_VERSION
@gamr13 Please enter the shown commands by @zgfg in Fastboot mode and tell us the result.
There is not much hope to restore your device after all that you have done wrong → but if you try, what we recommend, we may can recover it.
I can confirm: EVA-L09 is not the same device as VIE-L09 → you can not rebrand EVA-L09 to VIE-AL10, and it is not possible to rebrand VIE-L09 to EVA-AL10 - That causes a lot of problems and you should not be surprised if your device does not boot again.
If your original device was an EVA-L09 you can rebrand to all EVA models, but not to VIE models - That's why there are two threads - one for P9 and the other for P9 Plus.
If you flash oeminfos and related Firmware → it must match with your device!
But if you think, you can flash whatever you like, then your device get "bricked". And here we are now.
BTW: Rebranding back to your originally model can not be done with HWOTA7 - as long the device is on Android 8 ! First a downgrade from Chinese Brand Oreo to Chinese Brand Nougat is required → after this step it is possible to use hwota7 again to rebrand. I have written all the steps in separate Posts after the main Thread.
First we need this Fastboot mode information, then we can see in which status, on which firmware and which oeminfo your device is currently.
Then it's time to flash exactly this firmware with the correct method → for this step, wait for instructions from us.
Only when the device works again, it is possible to downgrade with the correct method and return to the original model, or whatever.
As long as the device is in a "brick", nothing works, since the "brick" must first be resolved.
If it is a "semi brick", a "hard brick" can happen as well, after that the device will be dead and without any function → It teaches you to be careful with flashing and get all the information before you flash anything.
We've also had other issues caused by users doing wrong actions - not knowing what they're actually doing. But both cases were solved successfully - which was not easy:https://forum.xda-developers.com/p9/help/huawei-p9-potentally-bricked-t3841197/
Hey guys,
I've attached a screenshot below which contains all the commands and what I got from them below.
Note about the get-build-number, that was the most recent firmware I tried to flash out of literally 10 other firmwares I tried.
I appreciate everything you guys are trying to do to help me fix this problem. I'm currently trying to survive with a Galaxy S3 Mini, and it's not going well in the slightest.
Cheers.
EDIT: Just as a note, which may be obvious from the screenshots to you or not, the partitions are like Nougat, meaning I do not flash the recovery to ramdisk.

Looks promissing
It says EVA, not VIE - ok
Somehow you are on c900b182 which means MM (not Nougat) - did you rollback to MM?
In Fastboot screen, does it show in red, at the bottom, both Phone (=Bootloader) and FRP Unlocked?

Why didn't you wait, you attempted to rollback?
Now Bootloader is unlocked but FRP is locked (and you cannot boot to System to unlock OEM=FRP)
It can block you fir further flashing ;-(
Do you want to go to c432, is it L09 (Single SIM) or L19 (Dual SIM)?

This was around a week ago, and the FRP lock thing went away when I did the rebrand - as it's supposed to
But yeah, I can't boot the system.
It's the single SIM EVA-L09.

Procedure for rebranding from c900b182 to c432 is here:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
Once on c432b182 you should receive OTAs to get back to Nougat.
However, procedure requires flashing OEMIFO, which most likely will be forbidden to you because your FRP is locked and you cannot boot to Systen to unlock OEM.
Which means serious brick
In that case you can try with DC Unlock (sorry, I don't know a better method), it will cost you 15 EUR (probably) and you must ask them for on-line help if needed

I was not writing you about getting the code but to use DC Unlocker to unlock FRP ( carefully read the story, posts #6 till #11, I gave you in the previous post)
Because their tool can unlock both FRP and Bootloader, but it costs more than just getting the Bootloader code
Personally I didn't use their tool (never bricked the phone or so to need it), and cannot help you about the tool further

P10 rebranding

Hello I'm the proud owner of a VTR-L09 P10 with the oreo based VTR-L09 8.0.0.364(c530) firmware and an unlocked bootloader. I have tried many tutos across the internet but I still can't downgrade it to nougat in order for rebranding to VTR-29.
Can someone with matching conf or a close one who has succeeded in rebranding can help me with a working tuto.
Thanks in advance and....
HAPPY NEW YEAR !!!!
First, you twist nougat and Oreo. Your phone is on Oreo and you wanted to downgrade to Nougat.
I don't know, why the downgrade didn't work for you, but maybe now it does with the correct understanding of versions (nougat is the older one).
If you're a bit experiment friendly, you can try something for me - but I really can't guarantee you that this will work without brick!
You need an SD card for this, don't try it without!
- Download your desired firmware from Firmware Finder. I recommend 8.0.0.382 for L29-C432, which I installed on my rebranded P10 yesterday.
Here are the links:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G2323/g1699/v202186/f1/full/update.zip
http://update.hicloud.com:8180/TDS/...l/VTR-L29_hw_eu/update_full_VTR-L29_hw_eu.zip
http://update.hicloud.com:8180/TDS/...86/f1/full/public/update_data_full_public.zip
- Download my oeminfo file and put it on SD.
- Download and flash this TWRP. It will ask you for a password at boot, type your phone PIN.
- Backup your oeminfo with TWRP on SD AND internal memory, just to be sure.
- Now flash my oeminfo file with TWRP via Install/Use Image.
- Go to my guide and follow now Tutorial #2, Oreo to Oreo, exactly. You can use the TWRP version you already installed, but everything has to be like in the tutorial.
It should work, but, as I mentioned above, I can't guarantee it.
The worst thing which can happen is that you brick your firmware. For this, you should be able to reinstall an L09 firmware after restoring your oeminfo file via eRecovery.
But I think the recovery will stop installing L29 if it didn't work with the oemfile - if so, you just need to restore the oeminfo backup.
Don't boot into your L09 firmware with L29 oeminfo!

First, you twist nougat and Oreo. Your phone is on Oreo and you wanted to downgrade to Nougat.
I don't know, why the downgrade didn't work for you, but maybe now it does with the correct understanding of versions (nougat is the older one).
If you're a bit experiment friendly, you can try something for me - but I really can't guarantee you that this will work without brick!
You need an SD card for this, don't try it without!
- Download your desired firmware from Firmware Finder. I recommend 8.0.0.382 for L29-C432, which I installed on my rebranded P10 yesterday.

- Download my oeminfo file and put it on SD.
- Download and flash this TWRP. It will ask you for a password at boot, type your phone PIN.
- Backup your oeminfo with TWRP on SD AND internal memory, just to be sure.
- Now flash my oeminfo file with TWRP via Install/Use Image.

Did you do the factory reset via eRecovery?
