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.

First you must flash stock recovery. You can extract from another full rom 7.0
Second you must have downgrade pack for your region and mobile operator.
Next you must have full rom 6.0 for your region.
You must have all file because you don't want debrand your firmware
Thanks, actually if i want debrand my phone whats the diference? Because I think I don't care...
Also, where can i find all of these files you write about?
I'm really lost with all firmware versions ... Does it matter if my version is EVA L09 C33B363 and i flash stock recovery from another version??
Also, my bootloader is locked, do I have to relock it? Does it even possible??

If you have locked you must unlock again. All file you can take from forum. Debrand it's unlock warranty and sometime you loose your guarantee. But what region you from

Here you have how debrand
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
If you debrand you can then flash stock recovery flash b300 and then b136 and do it wipe in stock recovery.
When you want debrand first you see your cust be c900 and then you must flash stock recovery do it wipe system/data and cache
If you do it your cust change to c432 and then must check your region using dial pad
*#*#2846579#*#* then push 3 and 4
If you see your vendor: hw and country: Europe
You can downgrade to b300 and then to b182
You lose your theme and you see ugly icon then do it wipe system/data and cache in stock recovery
After this you have update to b383 then b386 next to b391 and final to b393 or b394
I have b393

Question after rebranding from L09 to L29

Hello xda folks, actually my question is not about how to root or bad oeminfo or etc, actually, the question is this;: does our P10 has DRM keys?
second one, after unlocking my bootloader, i did a twrp backup of all partitions, system,data,oeminfo,cust,boot,etc, but while i was rebranding at first i did some steps really bad and i finished with a ONYX D88, then reading again i fixed and now i have the precious and delightfull L29 , but the real question is, what if i want to rebrand to my original VTR-L09C25 (this one is Latin America PERU ) and flash the original rom(btw i cant find it anywhere) and i tried to restore it via TWRP and didnt work, is there something im missing?
BTW: im not trying to go back, just in case who knows, warranty , thanks in advances dear xda folks <3

I am not exactly sure how to guide you, check this thread and my post too.
Here are the oem infos.
Me, i wanted to convert it to dual sim, when i flashed the oem info it bricked actually, it was entering erecovery only, no TWRP, and prompted me to download and install the original firmware, i did so, the first time was a failure but on the second attempt it almost booted, imade a factory reset and a clear cache and it works fine, it was converted to dual sim, and the firmware that downloaded was not the original one, but the one that matched with the oem info that i had flashed, that's how i did it.

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/...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!
