if you want OTA update you may relock BL

u can unlock with the same code anytime,coz your SN does not change
[Huawei P20 Pro Guides, News, & Discussion] damlancy:
Do I need to go under developer mode and unmark OEM unlock before using ADB to relock my bootloader? Please tell me the steps to follow.

Also, will this process reset my phone?
[Huawei P20 Pro Guides, News, & Discussion] Chiangwoo:
You'd better turn OEM lock off and relock your phone.

Of course it will reset your phone
[Huawei P20 Pro Guides, News, & Discussion] :
I followed the steps as said above, but the only difference is that I downloaded the same firmware (CLT-L29 8.1.0C432B120a) from FirmwareFinder and it also worked! I was on Cust605 and switched to Cust432 with no problems. Thank you!
[Huawei P20 Pro Guides, News, & Discussion] damlancy:
I was on C605 too. Did you relock your bootloader?
[Huawei P20 Pro Guides, News, & Discussion] marko68:
Sorry, I made a mistake in writing....I have relocked the bootloader, not reunlocked.

Sorry, I made a mistake in writing....I have relocked the bootloader, not reunlocked.

Anyway because serial number is not changed and Imei is not changed I think you can eventually reunlock it.

[Huawei P20 Pro Guides, News, & Discussion] :
Yes, to relock bootloader you have to use the command: fastboot oem relock (unlock code)

Confirm yes on phone.

Then, after wiping you can also desable oem unlock un developer settings so you have it like new.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
OK so I really hope for you that the lock isn't permanent, or you'll end up in the same boat as everyone else.

Ie: locked down bootloader.
[Huawei P20 Pro Guides, News, & Discussion] damlancy:
After following the rebranding steps you gave, will relocking my bootloader not make me kiss my ability to unlock at a future date goodbye?

so this is the guide to rebrand to c432 , how can i rebrand from c432 to c605 ? THanks
[Huawei P20 Pro Guides, News, & Discussion] tamaskurti:
I am sooooo BLIND.

For rebranding, the necessary modification at oeminfo line (like hw/eu or hw/ru etc) are in the filelist names from Huawei Firmware Finder.

Just look at Filelist:

- exclude Full and Public, and will remain the branding version. Ex: CLT-AL01all_cn

So the rebranding line will be:

./oeminfo CLT-AL01 C00 all/cn (for above example)

Again: I am soooo Blind.

:) :) :)
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I couldn't confirm that it would work as I've never done that.

AFAIK the 432 gets updates first
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:

Great I just updated! L29C432 to L29C605 151 version ??, c605 Latin America version
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
but im not sure if oeminfo file is the same with another versions
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Then that's a first.

If you were to change over to 605 then it would be on you.

There's a chance it'll work
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
how can you do that

what exactly you changed ?

and c432b??? to 151 ?
[Huawei P20 Pro Guides, News, & Discussion] tamaskurti:
Sincerely, I don't know.

I think that it doesn't matter --- it's my personal view.

My phone was CLT-L29C432 and I have rebranded to CLT-AL01C01 now.

(I have used oeminfo.bin file from this thread)

So I think, that with [MENTION=1599044]ToLive4[/MENTION] and [MENTION=2880355]dladz[/MENTION] guide you can rebrand any version to another.

One important thing tought: be careful with single sim - dual sim conversions, because those can brick your phone.
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
which version of c432 before you rebrand ?
[Huawei P20 Pro Guides, News, & Discussion] tamaskurti:
Yes... i"ve forgot to say: it was dual sim.
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
i mean b120 or b130
[Huawei P20 Pro Guides, News, & Discussion] tamaskurti:
Oh... OK. I think it was b120.
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
hmmmm , im on 131 now so still not sure should i rebrand or not :(

You shouldn't downgrade. AFAIK it can be risky.

I did a reset or wipe from twrp, then using the hurupdater method with c605 files I got my phone updated to 151

Must also mention, now also magisk 16.7 works before I could run version 16.0
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
really ? you reset your c432 from twrp , then use huruupdater only , no need to rebrand by code ?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Would you care to elaborate on what you did?

Sure there would be a lot of people here on 432-131 who would like to follow in your footsteps.
[Huawei P20 Pro Guides, News, & Discussion] oriveradel:
Nope, let me tell how I found out, my original phone was CLT-L04 Canadian version, I took the risk one day to flash a newer version released for L04 from Mexico using hurupdater, a d it worked except that it gave me the Boston chip under version info, however; everything worked just fine, later I decided to rebrand to CLT-L29 C432 using the procedure on XDA, from my experience I learned that crossing region for ROM works, crossing model numbers DO Not do unless using rebranding.
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
still not clear how exactly you do to go from c432 to c605
[Huawei P20 Pro Guides, News, & Discussion] oriveradel:
I Downloaded files from firmware finder (added model CLT-L29C605 ) rename the files as per hurupdater instructions, removed security password, rebooted to twrp ( I used all-in-one tool to reboot to twrp) performed a wipe, installed hurupdater zip from folder were all the files are, hurupdater installed with no errors, reboot, came back to twrp installed magisk 16.7 zip.
[Huawei P20 Pro Guides, News, & Discussion] hoangtu2410:
ok i understand that huruupdater way but you did this directly from c432 ?
[Huawei P20 Pro Guides, News, & Discussion] oriveradel:
Yes, as I mentioned before I took the plunge one day and flashed the Mexican update on my Canadian phone, both L04. Now I just did the same both L29. When I get back home I will redo the process and post a step by step guide.

Did you get magisk (root) to work?

Flashing twice worked for me, wipe w twrp, reflash files

Second option:

Copy OEM info binary*file*to internal*memory oeminfo.bin*(this is for C432, doing the next steps will edit to C605)

Make sure no password set on phone, so you always have access to twrp without encryption.

Enable adb debbuging in*developer*settings.

- Start ADB

- adb shell

- su

- accept the prompt at your P20pro

- mkdir /data/local/tmp

- mv /sdcard/oeminfo /data/local/tmp

- cd /data/local/tmp

- chmod +x oeminfo

- ./oeminfo CLT-L29 C605 hw/la

- exit

DON'T DOWNGRADE, follow manual step by step but download somewhere else appropriate version of files for debranding.

In your case B128 or higher with appropriate customization. In case that you want eu it's C432

second method make me cant boot , my phone will auto reboot to recovery . Luckily i backed up oeminfo before

Does it boot to twrp? Wipe, Run hurupdater process

i dont want to wipe again cause i setup everything done , the phone run ok so i think i will wait for next update
[Huawei P20 Pro Guides, News, & Discussion] tamaskurti:
It reboots because of rebranding and that triggers full system upgrade described in thread tutorial. After the upgrade it wants to make a Full wipe, factory reset, to finish oeminfo changing.

It is normal ... just follow tutorial.

Rebranding triggers Factory reset, full wipe.

Just make sure, that the recovery is the factory one in case of official upgrade/rebranding/factory reset, or twrp for "unofficial" wipe, and flashing with hurupdater for ex.

I debranded from UK L09 782 to EU l29 432. It then upgraded ota from 120 to 131. How do I upgrade to 151 firmware that's on c165? I tried with hrupdater but it did not work but that could be something I'm doing wrong.
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Yeah you're going to not want to flash firmwares for other regions, you're lucky HuRUpdater didn't work. It probably checks the region thankfully. Only flash firmwares for CLT-L29C432 since that's what your device is now. 151/152 is only avaliable for C432 via funkyhuawei at the moment which you need to pay for. It'll probably be publicly available within a week and then you can use HuRUpdater to flash it.
[Huawei P20 Pro Guides, News, & Discussion] dlads:

Very lucky.

By all accounts you can use the same guide to change over to a different model again, just need the relevant files for that model variant.

Personally never done this and I assume that 432 will be getting the 150+ update at some point soon in the future.

Yes it is possible but not by simply flashing a different firmware intended for a different model.. if it goes through you'll brick your phone.

As I said in my previous post you will need to re-brand the relevant model and then flash the said firmware of your choice.

Hi,

I just wanted to say that thanks to this guide I was able to rebrand a CLT-AL01 (Chinese P20 Pro) to a CLT-L29 C432. I followed all the steps given by OP [MENTION=1599044]ToLive4[/MENTION] and [MENTION=2880355]dladz[/MENTION], also followed the instructions given by [MENTION=9123062]Chiangwoo[/MENTION] to [MENTION=4637555]nsilva.android[/MENTION] in page 8 (https://xdaforums.com/showpost.php?p=76658830&postcount=71).

There was a difference in my procedure, I followed the guide https://xdaforums.com/huawei-p20-pro/how-to/guide-getting-started-unlock-twrp-root-t3806180 to unlock the bootloader and get root. Also, the phone was updated (damn night update) to the 132 version so I had to wait for the new C432 152 firmware to be released. I downloaded the firmware from Firmware Finder and followed the mentioned steps.

Thank you very much guys :D

You've missed some steps.

AFAIK the latter.

So long as you're on a prior version to 120 I would simply run through the guide once more.

Follow what's in my signature, you can't miss.

If you're on 128 or 130 /131 then don't do it.

Never downgrade.

It should work.

What are your full specs.

For example when I ran through the guide I was on the following.

L-09, c782, 110

Which after the guide I was on the following.

L-29, 432, 120

The guide in my signature will move you to 120 from 110, if you've moved on from 110 to anything above 120 then you'll need to change the file for the firmware and model you'd like to change to..

Haven't done that myself, I need to update my guide.

Thanks a lot for this [MENTION=2880355]dladz[/MENTION] and [MENTION=1599044]ToLive4[/MENTION]. I finally decide to de/re-brand my mexican L04. Just i think the guide could get a little better for new people checking and rewriting certaing things in a different way.

Some Pre-requisites may cause some confusion. I know this guide was thinkinng to make everything clear but at the same time for some new people may cause some confusion and some issues. For example, I was already rooted and with TWRP & Magisk installed using below guide

https://xdaforums.com/huawei-p20-pro/how-to/guide-getting-started-unlock-twrp-root-t3806180

Because of this I didn't have to installed Magisk or to perform the step 5 from the guide. I already saw people asking if they should reinstall magisk in the way the guide mentioned.

Another problem or doubt I have seen to be asked by a couple people is about step 9, if they have to press ENTER or not after you pasted the commands, even when is obvious it may not be for some, especially because the guide includes all the necessary ENTERs but it doesn't include one here. There was already a guy asking about this and another guy that failed because it was waiting for the "exits" maybe if he would have pressed ENTER and saw the prompt he would have known.

And last but not least on the error note that is mentioned almost at the end it is mentioned Allow the device to continue and it'll perform a factory reset but it didn't mention that at 99% the reset factory will fail, however, [MENTION=2880355]dladz[/MENTION] did mention this in one of his posts. I almost got a heart attack when i saw this error.

Just a humble opinion but like I mentioned I am grateful for this guide.
