I've only seen chat about it, depends what you call confirmation.

Well, I'm already converted, I'd be a poor guinea pig for this test.

I can't imagine a 20min wait would do anything. Can you remember the firmware you were on?

Regarding recovering from this seems like you've exhausted a lot of options, FunkyHuawei may be able to help further if you contact them
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Hmm ok so you're saying you did this guide first? Not funky?
[Huawei P20 Pro Guides, News, & Discussion] matthewacbroad:
yes I did this guide before funky. I bought funky in hope it help me recover.

Anyways guys sorry to say I had to exchange my phone. Since P20 Pro would require sending it away (leaves me with no phone) i had to pick Samsung 9 (as 9+ was 300 compared 9 was 0 dollars)

Thanks for the many help and I ADVISE P20 PRO CANADA USERS to very careful. I lost out of a awesome phone and now stuck with this samsung 9..

Least hope I can least root samsung 9 without problems

so far june 26, 2018 is the worst day out of my year (in terms of electronic loss/downgrade)
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Send it back they'll send you a brand new phone mate. You've lost nothing but time.

Definitely something to look at though.

Only problem I can see as to how this happened is because you were already on 128 or something was missed.

Bunch of people on L04 have already used this guide successfully so providing it's followed to the letter there shouldn't be an issue.

Send your phone back mate they'll send you a new one.
[Huawei P20 Pro Guides, News, & Discussion] matthewacbroad:
i doubt they would exchange this samsung s9 back and send out a p20 pro. They would of needed to send back the phone leaving me with nothing for weeks, as my number is a secondary to my family company it needs to be on!

ALL CANADIAN USERS LOOKING TO RE-BRAND YOUR PHONE ON TELUS NETWORK. PLEASE BE AWARE! I WOULD POST HERE BEFORE THINKING ABOUT RE-BRANDING.

The P20 pro is just a small memory i'll never forget (it's sexy phone). Now my samsung s9 (non plus) will have some adjusting to do.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I've already updated my guide.

The one you didn't read.

Contact Huawei and tell them you have no idea..your bootloader is locked right?

RMA it, bare in mind if the phone doesn't turn on and you can tell what's wrong, neither can they, if you know what I mean.
[Huawei P20 Pro Guides, News, & Discussion] smohanv:
Amazing instructions. https://xdaforums.com/showpost.php?p=76785704&postcount=152

I followed this and all success. I had this phone from 3 network and also not happy seeing Three logo on startup and shutdown. Moving from C782B110 to C432B120 using this guide is amazing and also has changed the phone in to retail version. Now I can flash Customised stock ROM. Thanks million.
[Huawei P20 Pro Guides, News, & Discussion] matthewacbroad:
i did not read that one. thanks for giving that warning. until theres more evidence of video pictures of someone rebrannding clt 04. :)
[Huawei P20 Pro Guides, News, & Discussion] dlads:
no problem, I did that guide as the other one although clear enough for me to follow, i knew it wasn't for others.

I suppose the lesson here is read read read.

Taking advice on face value when you'r playing with firmwares is a risky business.

Always check then triple check.
[Huawei P20 Pro Guides, News, & Discussion] matthewacbroad:
yeah ive unlocked and rooted: HTC incredible S, Sony Z3 compact, HTC 10, Samsung s6. I never followed the instructions wrong as one step could brick the phone. that being said there could be rpom for human error.

we need more people to try this out on CLT 04, I have 7 day wait time before my Samsung s9 oem unlock becomes available so i can answer questions if needed
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Junior member : Nox01

"Just letting you know after several times doing the process I got now my correct región, can't explain it, thanks a lot for your help. CLT-L04(C69) successfully converted to CLT-L29(C432)"

Search this thread for L04

There are quite a few people who've successfully done this process, even before i wrote my guide so definitely works mate?

The Huawei stands alone with weirdness when it comes to modification, my last phone was a Oneplus 5 which is almost unbrickable so this is a huge change for me.
[Huawei P20 Pro Guides, News, & Discussion] bowlandspoon:
Same as me lol. OP3T then OP5. Virtually indestructible! Huawei seems like a minefield at the moment. It's early days though. Hopefully in time things will become easier and less prone to errors. Treble should make a difference once it gets more established. Just hoping Devs will not leave the P20 Pro behind.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Honestly besides the crappy decision to lock down the bootloader I think it's a great buy, the camera sells itself and the performance is actually top notch, runs all the high end emulators which is no mean feat.

Plus the battery.

Treble actually works mate you just need to visit the last tab on the XDA app (forums) then choose project treble..

The problem we have is the installation.

Apparently the twrp we have doesn't do the job, phhuson has a great thread outlining exactly what to do.

https://xdaforums.com/project-trebl...opment/resurrection-remix-phh-treble-t3767688

Just make sure you have a way back to safety ie: nand or erecovery.

Afaik you need to be at pure stock, then whilst not rooted, flash a treble system img

PS: don't take my word for it, have a read.

I'll do a guide at some point when I'm feeling adventurous. Maybe Sunday :svetius: if I'm not drunk. :D
[Huawei P20 Pro Guides, News, & Discussion] bowlandspoon:
Yeah I've been keeping an eye on it. Seems like there's just too many compromises at the moment. Time will tell.

Agree with you re the bootloader, really stupid move from Huawei, it will without a doubt kick development into touch.

Might have a go at installing Lineage over the weekend and checking out the camera port. Let's face it the P20 Pro is all about the camera! My ROM choice (although limited at the moment) pretty much depends on the camera!

Good luck with the guide, i'll be looking forward to following it.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Well I need one success story, whether it's my own or someone else's.
[Huawei P20 Pro Guides, News, & Discussion] bowlandspoon:
I'll let you know how I get on. Right now I'm watching England!
[Huawei P20 Pro Guides, News, & Discussion] chrisrk45:
I have the same problem

Anyone knows how i can revert this ?

My CTL-04, now is a CTL-29 but is setting to Chispeto-boston

HELP PLEASE!!!
[Huawei P20 Pro Guides, News, & Discussion] popoxee:
Mine is a AL00 Rooted version.

Follow this guide, skipped step 1,2,5 because mine is already rooted

After all finished, it restarts and updates, but failed in the middle - no error provided

Restart, tried to download full recovery, failed - no error provided

Restart again, boot into system - REBRANDED SUCCESSFULLY to CLT-L29!

Check settings and tries to update - no update available

Not sure if the failed update will affect any functions... Any suggestions? How can I do a full OTA flash?

Edit: after reading other's comments, same happened to me. The build is showing Chispeto-boston

Edit 2 IF YOUR BUILD IS SHOWING Chispeto-boston

Follow EVERY step in this guide: https://xdaforums.com/showpost.php?p=76785704&postcount=152

It is a clearer version of OP's instructions.

Make sure you do every step, including magisk img and apk, even if you are already rooted.

If you still see that, redo every step once again. It worked for me.
[Huawei P20 Pro Guides, News, & Discussion] Chiangwoo:
flash again without change oeminfo steps

Now i have a nice C432, but my camera dosent work anymore...

'Any Solution to fix this problem? :eek:
[Huawei P20 Pro Guides, News, & Discussion] dlads:
? Ok this is a first. What exactly is happening?

I admit that my 60fps video on the camera lags a lot, it's unusable. But the rest is fine and it did work when at complete stock so may be something I've done
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
HI, i was wondering if I rebrand from C782 to c432, how to revert back, in case i wanted to sell the phone
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Why would you want to revert back? You haven't broken the phone you've enhanced it.

You don't need to revert back.

I've heard from one user who I know who went back and he bricked his phone.

Theoretically it's possible but you won't find a guide I don't think.

And as I said, you don't need to.

432 is the preferred model.
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
Yeah but that report of broken camera is worrying
[Huawei P20 Pro Guides, News, & Discussion] dlads:
So I would say, factory wipe.

What do you have installed?

Did your restore anything ?

What did you do from process to present day? Don't miss anything out.

---------- Post added at 12:52 AM ---------- Previous post was at 12:50 AM ----------

Bare in mind my camera was perfect, after my titanium restore my 60fps is horrible, it's now 10 fps
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
HI, finally decidint to to do this, do i press enter between step 9 and 10
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
Tell me please that you are joking ???

Yes, press ENTER between step 9 and 10
[Huawei P20 Pro Guides, News, & Discussion] dlads:
:D:D
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
Welll... I can see your point now :)))
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
When you set oem attributes to eu/hw it will show only vanilla/non branded stuff
[Huawei P20 Pro Guides, News, & Discussion] Chiangwoo:
that's great. if I want L29C636, I just at step 16 ./oeminfo L29C636 hw/as

Is that right ?
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
I'm not sure because it's oeminfo from L-xx C432

But you can always try
[Huawei P20 Pro Guides, News, & Discussion] Chiangwoo:
thanks for reply.

yes I'll try it tonight but

my phone is CLT-AL01 Chinese edition,and how to backup my own oeminfo file ?
[Huawei P20 Pro Guides, News, & Discussion] robot1000:

In terms of the new firmware, can anyone tell me if WiFi calling works (in particularly on Three Network)? Thanks

[Huawei P20 Pro Guides, News, & Discussion] mcklane:
Thanks, sorry but I got few questions:

Q1: step 5: how do i install the apk, i suppose i need to boot into android after step 4?

Q2: step 6: can i copy the file during step 3?

Q3: step 20: all the commands pasted all in one go in the adb shell window or one at the time?

Q4: after this process will the phone still have the no check recovery installed or is that overwritten during the upgrade?

Q5: how do you full wipe, from the android menu or in recovery or what else?

thank you
[Huawei P20 Pro Guides, News, & Discussion] robot1000:
Did your region change as well?
[Huawei P20 Pro Guides, News, & Discussion] 3lp:
Thanks for your work!!!

Hi, I followed exactly the ToLive4 initial guide, that is your guide except for the last point. I don't made a full wipe.

Now my phone show the correct model L29 but only one SIM icon.

I haven't the dual sim tray yet, do you think with only one SIM, or the single sim tray the option of SIM 2 is disabled?

Can any one with a rebranded P20 Pro confirm my doubts?

Cheers! :)
[Huawei P20 Pro Guides, News, & Discussion] shadowfight:
Thanks! I have already rebrand my clt-l09c 782 to L29 432, as the brand is L29, I think there should support dual sim. But it could not verified as the tray is only one sim. In system there are no dual sim settings also. But everything else working fine. It could be rooted and installed xposed.
[Huawei P20 Pro Guides, News, & Discussion] fishersfish:
Here I want to share the steps how I bricked my phone

First of all, I thought I can handle it ,so I didn't follow the guide step by step.

My phone : P20 Pro (CLT-AL01 C00, rooted) ,I want to rebrand it to CLT-L29 C432

IMEI checked in Firmware Finder : Compatible with CLT-AL01 C00 BUT NOT compatible with CLT-L29 C432 ( I've heard that chinese model's baseband is different from others )

The following is the steps I proceeded (DON'T FOLLOW):

I downloaded nocheck eRecovery, oeminfo and 3 zipped packages provided by OP to USB stick; Downloaded unofficial TWRP to USB stick

Flashed TWRP in fastboot mode and booted to Recovery

In TWRP, I copied oeminfo to /data/local ,not to /data/local/tmp

In TWRP, I copied 3 zipped packages to /data/ota_package NOT to /data/update/HWOTA (lazy)

In TWRP, I excuted "./oeminfo CLT-L29 C432 hw/eu" , no error returned

In TWRP, I added the corresponding commands like: "--update_package=/data/ota_package/update.zip" to /cache/recovery/command & checked the file

In TWRP, I flashed nocheck eRecovery and then rebooted to the recovery.

eRecovery prompted "updated failed".

I tried to reboot to fastboot mode, in the neanwhile I fogot pressing Vol- ,the system refused to reboot system and got back to official recovery

I rebooted to fastboot mode ,found that "frp locked" prompt occured, then I Flashed TWRP failed.

I oem relocked the phone ,thinking it may solve the problem, but the phone refused to oem unlock again, because of the frp status.

In official eRecovery, I tried "download latest package and recovery", but it always told me "getting package info failed"

Force Flash mode doesn't work, it keeps telling me "incompatible package downloaded". Tried firmwares for CLT-AL01C00 and CLT-L29C432.

The phone's current status:

OEM locked, frp locked

The phone refuse to boot the system (still CLT-AL01C00,EMUI8.0.1.109, rooted before), so I cannot disable frp

nocheck eRecovery and official eRecovery installed, both are bootable

Since the prompt "frp locked" shows up and the system refuse to boot, OEM info should have been changed ( such a prompt in Chinese model is impossible)

I think there are 4 reasons why rebrand failed: [Figuring it out if I am wrong is appreciated]

Not following the guide and operating step by step

updating from other folders is not allowed in nocheck eRecovery

oeminfo is incompatible with Chinese models

I shouldn't boot to the system directly until I installed the new one or recovered the former oeminfo.

It's my first time to buy a huawei phone (and it will be the last time). I will wait 6 months for every unbrick news from FunnyHuawei and DC-Unlock, then I will consider to call Huawei Support Team for help.

Have fun to enjoy my brick journal! :o
[Huawei P20 Pro Guides, News, & Discussion] shadowfight:
You could use official huawei suite to debrick your phone and try to unlock again. It should work if You could enter fastboot.
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
If you could enter fastboot you should unlock bootloader and follow my instructions step by step from beginning. Don't flash twrp, instead flash no_check_recovery and patched ramdisk. After that you will probably can to pwr on the phone and follow rest of steps
[Huawei P20 Pro Guides, News, & Discussion] reeved:
Does this method give you EU firmware? I have a L09 706 phone (NZ) and the updates are so slow that I'm tempted to rebrand it to an EU version which receives much faster updates. If it does give you EU firmware, will it also receive EU updates?
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
Okay got my eu L29 model now, now how to lock the bootloader

Sorry figured it out now

Command is

fastboot oem relock ( Phones unlock code)

without ( )

Yeah got the 128 update straightaway.

firmware finder shows 131 but cant be installed, Now the search to install 131 starts!!!
[Huawei P20 Pro Guides, News, & Discussion] dlads:
That's correct the 131 update isn't available for 432 yet, the L29 version afaik makes no difference.

I've read that people have used the Hur updater to move to 131, Romaur is also on 131
[Huawei P20 Pro Guides, News, & Discussion] sudman:
OK got bored of waiting and used the guide to update my rebranded L09 (C432) to B131 from B128. Let see if I notice any improvements.
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
which guide did you use mate
[Huawei P20 Pro Guides, News, & Discussion] mrnovanova:
A bit confused about this step. E) Rooted with ramdisk-CLT-L29-MAGISK.img fastboot flash ramdisk CLT-L29-MAGISK.img

I'm on L-04 already rooted and when I flash this image I lose root. So is the goal to retain root and skip that step or to flash is as a prerequisite for of rebranding and lose root?
[Huawei P20 Pro Guides, News, & Discussion] sudman:
Hi Yogesh, used the guide in the 1st post. Just left out some bits like oeminfo as its no longer required if phone is already rebranded and renamed the B131 firmware files so that they matched the guide.
[Huawei P20 Pro Guides, News, & Discussion] bowlandspoon:
KANGVip is also on 131.
[Huawei P20 Pro Guides, News, & Discussion] mrnovanova:
whatever I do. I get stuck at the oem info lines. No such file exists.

Edit

Figured it out. Everytime I messed up the oem info file it got deleted from my sd card. Ended up copy pasting every line then the device kept booting up into TWRP so I did a factory reset and now I'm CLT-L29.
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
Thats nice, what is main difference you find!!
[Huawei P20 Pro Guides, News, & Discussion] dryspuri:
is there way to go back to L09 c782
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
Yes, but you must find c782 files and change line for oeminfo edit to appropriate
[Huawei P20 Pro Guides, News, & Discussion] mangusZen:
Oeminfo file remains the same for all type and regions?
[Huawei P20 Pro Guides, News, & Discussion] Aodrulez:
Hi everyone,

First of all, thanks for the guide. I just recently bought a P20 Pro from China (CLT-AL00 C00). Using the guide, followed each step correctly & got it rebranded to CLT-L29 but my chipset says "Chipset-boston". When I tried to root again by getting into bootloader to fix this by retrying same steps, it shows "bootloader unlocked, FRP lock". This means I can't reflash the ramdisk image. My phone works fine, it's just that it won't get any updates due to wrong chipset information. Any help to get root again on the device would be highly appreciated. Thanks in advance.
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
It looks that you skipped or miss typed something in oeminfo edit line. Check it again.

Also do everything without Google account
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
Practically yes, just need to be edited correctly
[Huawei P20 Pro Guides, News, & Discussion] Aodrulez:
I can't get root on the device now as "FRP lock" is active. Unless that's disabled, I cant flash patched ramdisk. Has anyone gotten out of this scenario?
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
It looks like that you started process with some security feature turned on and without of removing Google account :(

Try to install Magisk manager to check will be super su available. If yes, then install terminal emulator and retry from phone directly
[Huawei P20 Pro Guides, News, & Discussion] Aodrulez:
No joy. Doesn't make sense as to why FRP lock message is active in bootloader.
[Huawei P20 Pro Guides, News, & Discussion] Chiangwoo:
enter the developer mode and turn off the oem lock.

then your FRP unlocked
[Huawei P20 Pro Guides, News, & Discussion] JamieD81:
Just thought I'd chime in since not many L04 users have and say I rebranded my Canadian L04 pretty easily with only 1 issue, first time I rebranded I made a mistake by missing update.zip *I dunno how?! lol* anyways it threw an instant boston build at me, second time I rebranded I did everything except the oeminfo stuff and the rebrand went smooth as butter. Canadian L04 stuck on 109 to L29 and update to 128.
[Huawei P20 Pro Guides, News, & Discussion] Aodrulez:
Thanks a tonne, Chiangwoo!!! That did it! After that, just repeated the process once again & am fully rebranded from AL00 to European version. Got even the updates.

[MENTION=1599044]ToLive4[/MENTION] : Thanks again for the guide. And I'd highly recommend adding this somewhere in the initial post itself that 'FRP lock' in fastboot mode can be disabled by enabling bootloader unlock option inside developer options menu. Yesterday while I was stuck at it, did some research & it turns out alot of people have bricked their devices by locking the bootloader while FRP lock is in place forcing them to go for paid services to recover.
