IMEI won't change from this process in any way.

Bootloader unlock code will continue to function and this process will not lock your Bootloader.

You can relock your bootloader but personally I wouldn't bother. AFAIK I'll say RE-LOCKED which means it's still been tampered with, so for me no point.

The process can be found in the OP or in my signature, either guide will work, so long as you don't downgrade strictly speaking you may change to any variant again so long as you don't downgrade.

You will provide the files for the process as others have, the process remains the same.

Downgrade example: 131 - 120

You must up up.

There is another process to downgrade but I see little point in it.

Could you point me iin the rigfht direction tot he files that would be suitable foir my debrands path as i think i no wheren to find l29 131 update zi[ps but do i need a different vcersion of oeminfo than the one you provide? and ists is deffiontiely safe to goi from l09 to l29 and if i were top brick it s usually recoverable isnt it and if i didnt want tio rebrand ot dual sim what do i change abotu oyur guide to just rebrand l09 to l09 c782 to c432

[MENTION=7420524]nubston[/MENTION] I believe the OEM info needs to be bespoke to the firmware you're flashing.

Yup, that was the exact files I used and now I'm on 159(C432) from 133(C732) I believe.

The guide no, the files perhaps. The quote above saw someone successfully use these files to debrand which is brilliant, but it's at your own risk.

I would say you need updated files, I've not provided them as they will be updated continually and I won't have this phone much longer so won't maintain the thread.

Well i finally got it right on my second attempt today.

Initially got myself stuck in a soft brick / bootloop which terrified me... used the e recovery and started over, got it right this time.

I've got from the 3 firmware which was several revisions old to the 156 firmware, all the 3 rubbish gone, device much better and more free space to boot. Coming from an s8 plus I am seriously impressed with the p20 pro.

Absolute travesty of a situation if you ask me, thank god was able to debrand and swap firmwares!

Dual SIM functionality cannot be obtained using this method. Currently, no free method for doing so exists.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Either the 6T or the 7

Nothing what out there seems worth it, Pixel 4GB of ram? That's crap, especially when you consider the asking price.

Poco looks alright but I'd say OnePlus are leading when it comes to development and following, they're superb phones

---------- Post added at 12:16 PM ---------- Previous post was at 12:15 PM ----------

Funky is the only known way to get this working but certain things will alter so your original bootloader unlock code will cease to function.

Not worth it IMHO
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
I have caved in and went funky way!!

i also have oneplus 6 but screen in comparison to p20 pro is not good, camera is not good enough, so I made my p20 pro dual sim

Yea I need OIS throughout tbh or spectacular EIS.

The 6T is supposed to have it throughout which is nice and I'm sure the 7 will.

[Huawei P20 Pro Guides, News, & Discussion] Noxilus:
Hello everyone,

First of all, thank you to the persons who helped creating this guide.

I'm about to debrand my Huawei P20 Pro (L29) to get rid of the annoying retail mode.

The files in this thread are a bit outdated as I'm currently on CLT-L29 8.1.0.130(C33patch01)

This comes from a French operator.

Now my question is, in order to follow this guide and successfully debrand my phone, am I supposed to use a firmware corresponding to the version I'm aiming for (C432) with the oeminfo file you provided, or should I use a version of the firmware I'm currently running on (C33) along with your oeminfo file ?

On the Team MT website I'm able to find the following firmwares, both being the latest versions of each brand :

- CLT-L29C432B161 (8.1.0.161) for C432

- CLT-L29C33B134 (8.1.0.134) for C33

Edit :

Alright, I got it working ! :D

So after thinking a bit about my own question, it appeared to me that the former choice made more sense. Since I'm trying to debrand to C432, I assumed I was also trying to install a C432 firmware (genius right ?).

I went ahead and downloaded the correct files from the Team MT website, i.e. CLT-L29C432B161 (8.1.0.161) which is the latest C432 version I could find. I can't link the website or the files because of the new user limitations. If anyone wants them, you can ask me in PM.

These are the only files I downloaded that differ from OP's post, well not exactly since I used the latest stable version of Magisk which is more recent that the one cited in the original guide.

But other than that, I used his oeminfo and recovery_ramdisk_nocheckP20.img files.

I followed the guide exactly and I came from CLT-L29 8.1.0.130(C33patch01) to CLT-L29 8.1.0.161 (C432)

Did you have any luck rebranding? I have the same phone as you and I have the same questions.
[Huawei P20 Pro Guides, News, & Discussion] Noxilus:
I used the website advertised on this thread (MinistryOfSolutions).

It looks really shady as you're purchasing the code to a seller through a chat and are paying with PayPal through the "Send money to a friend" feature.

But it's in fact legit, he gave me the code within 1-2mins max and it worked, I could unlock my bootloader with it.

It costs 30€ though, that's quite a lot for a code. But since Huawei isn't providing them anymore ... Looks like it's the only currently available solution.

No need to quote two massive threads mate.

The files are redundant anyway. I wasn't aware that they'd been taken down though, so thanks for that.

The files required are still listed in both guides.

You would require newer versions anyway which you would need to acquire yourself as others have , may be worth asking others who have obtained them.

A little search here will bare fruit I'm sure, or other users would have potentially bricked their devices.

Well the steps I know of are within my signature.

If your device is a retail one then strictly speaking you should not have it.

I've worked in the industry and I know how they look at these things.

That being said so long as it's just a normal device the steps in my sig will work.

You'll need newer or the same files level to firmware you have.

Following on from this I manged to go back to my original model no CLT L09...

As confirmed by [MENTION=1851161]sajibcy[/MENTION] ./oeminfo CLT-L09 C432 hw/eu worked succesfully.

I did manage to mess up mid way as i didnt rename the 1 zip files correctly for the echo command flash, so i half flashed the firmware, luckily there was NO brick and all that was affected was the rom (v161) looked different and i had the boston chipset for build.

After various attempts going back and forth retrying the ./oeminfo command without flashing the firmware again, i had no success with the boston chipset budging, however i did notice when trying CLT-l09 it gave me a boston chipset and then trying the CLT-l29 it showed correctly as l29, that when i had a feeling my flash using the echo command was not succesfull, but there is no indication for this, the command just writes or sends to the device and on reboot i did see a failed update message at 100%. I then decided to use HURUPDATER to flash the firmware (v161) and thats when i realised the zip file was not renamed correctly as i saw it in the script during the flash process and was missed when i followed the rebrand tutorial. I renamed and re run hrupdater zip and BINGO IIT WENT BACK TO L09 succsfully v161! Im so happy i was worried about bricking it. I was even contemplating going back to v120 files but i didnt, I was on 161 and reflash 161 but used l09 firmware files.

Now im back on L09, magish root is gone / removed, there is no app, abd shell SU confirms Not found, recovery is stock and boots to erecovery OK and bootloader is now locked ready as it was out the box! no more device has been unlocked and insecure during bootup.

I managed to get to this stage with a bootloader unlocked, rooted and twrp.

Use this at your own risk. Hope it helps for those who want to go back to stock for what ever reason.

Its a shame huawei dev / roms is lacking and i dont think will improve, i looked to this phone for the camera + hardware and dev community like the other huawei but its a shame. Maybe android in general is changing and dev scene is changing due to improvements with android it self. Anyway.......:cool: Hope this helps someone.
[Huawei P20 Pro Guides, News, & Discussion] Jacobddu:
I've done the debranding from a CLT-AL00(a Chinese retail version) successfully almost 6 months ago. And at that time the ROM version was C432B120 bu can not receive the OTA. So I used the HuRUpdater to manually update the ROM after 2 months and then the ROM is C432B152. Until now, I still can not receive the OTA no matter I relock/unlock the BL. And if I go to the recovery mode, the phone can connect the server, but the recovery ROM version is still C432B120.

As P20Pro can not be downgraded, so I don't try it.

I think maybe Huawei has a database which contains all the IMEIs. And mine is recognized as CN version so can not receive the EU version OTA. Will contact Huawei support for help or flash back to CLT-AL00, but I forgot backup the CN version oeminfo.bin.
