Hello, I'm here to share my experience with P20 Pro CLT-L09 C55 (Italian TIM carrier).

I followed [MENTION=2880355]dladz[/MENTION] guide on post #152 and successfully rebranded my phone to CLT-L09 C432 (European version).

Insted of using the .zip files provided with the guide, I downloaded them form Huawei Firmware Finder, in order to get the latest build available at the time (B131).

I used oeminfo, MAGISK and "recovery_ramdisk_nocheckP20.img" from the guide.

First, I tried with "./oeminfo CLT-L29 C432 hw/eu" and everything worked but it gave me the strange "Chipset Boston" issue.

Then, I did the same procedure, but I wrote "./oeminfo CLT-L09 C432 hw/eu". Now it shows the correct build.

I also relocked the bootloader with fastboot oem relock.

Now the device is fully functional and debranded. Stock recovery, locked bootloader and no root.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Very clever, to be honest i should update the guide to reflect this, just need the files.

Would need to run through it again or at the very least have a guinea pig run through it for me.

I've already re-branded so can't do it myself.

Did you alter anything other than what you've written?

Tbh, anyone who's done the original guide could just update via HUR updater but this would kill two birds with one stone.

Did the rebrand from 09 to 29 of a german vodafone single sim. so the dual sim option is now available if i search for it, but it is not recognizing secound sim card and if i want to turn on or of sim 2 it says: "Fehler Deaktiv. SIM-Karte"

Any suggestions how to fix this?
[Huawei P20 Pro Guides, News, & Discussion] Dogez:
No, the only thing I changed was the oeminfo command and the name of the .zip files downloaded from Huawei Firmware Finder, because they're different from the files on the guide.

Also, this was my first HUAWEI / EMUI smartphone and I still don't know much about it. For example, I thought each model had a different oeminfo file, but in this case I simply changed the command and everything worked.

What did this line "./oeminfo CLT-L09 C432 hw/eu" actually do?

Thanks for the guide anyway.
[Huawei P20 Pro Guides, News, & Discussion] djSufi:
How did you do it the second time? I followed the instruction and got stuck with weird boston issue. However, now my Windows 10 won't recognize the correct driver anymore so I can't do ADB which means I can't follow the instructions anymore :( if I manually boot the phone into bootloader the fastboot commands work, but when I am back in the system, the ADB doesn't find any device. Anyone knows what I can do to fix this?

My experience with this guide

Hi All,

I followed step by step the whole guide and below my results:

1. before rebrand: P20 Pro CLT-L09 (C432), vodafone (Germany), single sim, sw 8.1.0.128

2. after rebrand: P20 Pro CLT-L29 (C432), no brand anymore, dual sim not working, only single sim, OTA update succesfull done to from 120 to 128.

I have a queston to whom, they say dual sim worked after the rebrand: could you please tell us which is the model, before you did rebrand, and in case you used steps, in addition to the ones from the guide?

Thanks
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Dual SIM does not work if you debrand this way. I converted to CLT-L29 (C432) and ordered a dual SIM tray to check, it doesn't work. Converting is only useful for updates. If you want functional dual SIM you must use FunkyHuawei but this will relock your bootloader and it can't be unlocked again.
[Huawei P20 Pro Guides, News, & Discussion] Kodin75:
Matt,

thanks a lot your fast replay.

So do you agree we can definitely confirm that this debrand procedure will not bring up the dual sim functinality, despite some members said it did work?

This is a final and serious statement which I like. :)

One additional question about FunkyHuawei: did you try to use it and dual sim worked? I do not care to lock the bootloader, I'm not planning any further mods.

For me what's important:

- have a phone fully working, with dual sim as well

- OTA update

Is this possible at moment with FunkyHuawei tool, paying of course?

In my case I rebrand my phone from CLT-L09 to CLT-L29. Now it's CLT-L29, so using the Funky tool, should I refer to which ROM, L09 or L29?

Thanks,

Kod
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
I've seen members saying that the setting for dual SIM functionality comes up but haven't seen any that it actually works. I have the setting, I got a dual SIM tray and have a spare SIM so tried it, it doesn't work. Can you link me to some posts that say the actual functionality works?

So if you don't mind the bootloader getting locked FunkyHuawei would work to get dual SIM actually functional, OTA updates, and yes you do pay. I'm unsure what the implications are now you've used this method but if you contact FunkyHuawei I'm sure they'd be able to help/explain if it's still possible.
[Huawei P20 Pro Guides, News, & Discussion] Syph0nX:
Has anyone done this on 131 firmware? I'm already on L29 C432 131 firmware. I just want to remove the carrier branding. Will my device still be factory wiped even though I'm not moving from L09 to L29 as I did this already with Funky Huawei.
[Huawei P20 Pro Guides, News, & Discussion] oriveradel:
Where did you find 132 firmware?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
It quite clearly states in the OP in red writing that this method does not convert your phone to a dual SIM variant, more so; if you do use the funky method, you lose the ability to re unlock your bootloader, which for most people who visit XDA is essentially the end of the road.

The vast majority of people ( strangely enough ) visiting this thread are actually people who just want to update.

For me I need that ability to root and use the tools I've been accustomed to for many years.

If you're of the prior group then by all means use their method.

Personally I'd avoid it like the plague.

PS: performing our process does not affect your ability to use their method.

Your call.

---------- Post added at 08:30 AM ---------- Previous post was at 08:29 AM ----------

Must be a typo

Edit: scratch that it's official, Chinese I believe, not sure as to what it brings, could be a regional update.

Personally I'm vexed at Huawei, their system of updates is just awful. A total mess.

I'll never buy another of their phones, I'm failing to see who this splintered , broken model / update method benefits.

Coupled with their decision to lock down the bootloader? They're literally making the same mistakes that HTC made. And for all their good (HTC) they never recovered.

Huawei are going to do the same thing.

When the pixel 3 drops I'm going to buy it, I've had about enough of this madness, this is meant to be android, what Huawei has attempted to do is make their own OS and little world but they've failed monumentally to accomplish it, their phones are bloated, slow and unoptimized.

It's a shame as the specs and the potential this phone has is amazing, it's like they purposefully tried to hinder it.

Sorry, mistyped, should say 131

---------- Post added at 10:43 PM ---------- Previous post was at 10:39 PM ----------

I used Funky method, it doesn't look your bootloader after completion. Mine remained unlocked and I've rerooted successfully after as well. However your unlock code does change so you do need to request another.
[Huawei P20 Pro Guides, News, & Discussion] gm007:
Hi,is it possible to rebrand from c185 to c432 with this tutorial?and do i have to use the firmware listed in op or newer one? I have l29 c185b130.

Thanks in advance.
[Huawei P20 Pro Guides, News, & Discussion] Grancapitan:
I can verify that the dual sim of this thread is nominal and, as long as a sim manager appears, or something similar, but that the second sim does not allow to operate with it.

If it works with the funkey method, as you say but it has 2 serious effects that, until very recently (until we started to claim), I did not notice them: the bootloader lock (the Huawei code does not work for you and you are NOT given the new code) and the change of internal imei (that @ pretoriano80 told me and that can be seen with the command fastboot oem get-psid).

Result: if you have any problem, forget about going to Huawei and ... pay again with Funkey !.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
You won't be able to request another, the code required to unlock your bootloader doesn't change meaning you can't re-unlock, if you've remained unlocked then keep it that way.
[Huawei P20 Pro Guides, News, & Discussion] gm007:
Anyone?
[Huawei P20 Pro Guides, News, & Discussion] Syph0nX:
Hmm I did request another but can't be sure if they gave me a new one or the same.... But I don't have any plan to relock the bootloader.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
From what I can recall it's the serial number which you provide to obtain the code and I don't believe that will change after the process so the code output would be the same, although with the de-branding process I think something else changes so it doesn't work, but again I've not done that process so.

Edit: I'm referring to the funky method btw

Hey dladz,

Originally on CLT-L09C782 (.110) used this guide to get to CLT-L29C432 (.120).

OTA'd to .128 without issues.

OTA'd to .131 without issues. Got the notice for .131 two days ago.

.131 mentioned some A.I. improvements on the camera and other bug fixes.

Yea I've been waiting for 131 for some time to be honest, might just use Hur updater.

I was following your guide but now I'm with an unknown device...and no firmware version...

Model: UNKNOWN

Build number: chipset-boston8.1.0.001 (01F4)

Please Help!!!

Flash the firmware twice.
[Huawei P20 Pro Guides, News, & Discussion] hecz0r:
Thank you so much for the guide. L09-C782 here. I've done everything, gotten on C482 v131. Since I couldn't pass SafetyNet (CTS profile mismatch) in order to use Snapchat, I tried locking the bootloader.

This went fine, data wiped the phone - but after the reboot eRecovery came up and I couldn't get back into the OS.

I mention I never installed TWRP, only the patched Magisk ramdisk, and after that the nocheck.img ramdisk.

I had to reflash via wi-fi or I couldn't get it to work. Now I'm on v110 C782 for some reason? Hasn't v130 been released for this branch?!

Two questions then - how do I pass SafetyNet? I had NO tweaks installed and have tried Magisk Hide yet Snapchat wouldn't log in.

Secondly, how do I lock the bootloader back? I think I want to lock it in order to get proper OTA, right? Or is getting OTA possbile while the bootloader is unlocked?

I'm interested in using Snapchat and getting official OTA from c432 branch, not really wanting to use root or custom roms just yet, wanted to use EMUI a bit longer until I completely go crazy because of how miserable it is :D
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
You didn't edit oeminfo properly. Copy oeminfo file to root of your storage and repeat that step

6. With your phone still turned on in the system and connected to your Computer go back to the CMD / ADB prompt.

7. Type: adb shell

PRESS ENTER

Type: su

PRESS ENTER

NOTE* Accept the prompt on your P20 Pro by pressing: Grant

8. Type: mkdir /data/local/tmp

PRESS ENTER

Type: mv /sdcard/oeminfo /data/local/tmp

PRESS ENTER

Type: cd /data/local/tmp

PRESS ENTER

Type: chmod +x oeminfo

PRESS ENTER

Type: ./oeminfo CLT-L29 C432 hw/eu

PRESS ENTER

Which version of magisk are you using ?

I think it was 16.2? I can't remember. The file is called "eml-lxx-magisk.img"
[Huawei P20 Pro Guides, News, & Discussion] Kodin75:
I used Funky and below my update:

1. after my conversion from L09 to L29, single sim, sw 128, I used funky eRecovery to go back to sw 120 (1 credit) --> worked

2. used FHP20SingleToDual to convert dual sim --> worked (5 credit)

3. OTA update sw 120 to 128 --> worked

The sw revision 131 not yet rolled out officially by Huawei, waiting for next OTA, hopefully it will work!

After single to dual conversion I noticed that bootloader code doesn't work any more, even if:

IMEI --> same

Product ID --> same

Phone Serial number --> same

My concern is now: why is the old bootloader not working any more after conversion, if the inputs for the codes generation stay the same?

I suggest, who used the method here and convert his huawei from L09 to L29, and to by just 5 credits and use my step 2.

Kodin
[Huawei P20 Pro Guides, News, & Discussion] srmanuel:
I thought that your IMEI changes when you use Funky. Is it safe to use then?

Do you think that you can still use your warranty?

Also in their webpage after using FHP20SingleToDual they say this

: After a short wait, your phone will be rebranded. Note that in About Phone, the correct information will not be displayed until you follow the next step...

Now, follow the installation instructions to install firmware matching your new branding.

Did you skip this step and just downloaded the OTA ?

Please tell us any changes that you expriment or make. I want exactly the same as you . (A dual sim pone which can receive OTA updates without any plans to keep modifing my pone after everything Works)
[Huawei P20 Pro Guides, News, & Discussion] marko68:
Sorry but wasn't working... Still the same.

I've done everything with funky Huawei tools, in 20 minutes everything was done, debranding and new firmware. Fantastic

Do you have Xposed installed ? Did you use the IMG or the zip? I used the zip.
[Huawei P20 Pro Guides, News, & Discussion] JamieD81:
I re-did the entire process when I hit Boston but I skipped all the oem stuff on the second time. Also make sure you have all the zip files because I believe I skipped update.zip on the first run which you may have done as well.

You managed to unlock your bootloader again? After using funky Huawei? How did you do this?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
You re-unlocked it after using the funky Huawei method ? And you have dual SIM functionality?

You'd be the first person this has happened to if that's the case.

If so well done but I have my reservations.

If im honest, I'd say funky finished what we gave you and you started..

If that's true then you've paid for something you had for free.

You see the funky Huawei method of de-branding is so in depth, it actually changes the logistics and dynamics of your device, activating the second SIM tray.

However the down side is that you would lose the ability to unlock the bootloader because your device although changed wouldn't have a different serial number.

So it would never re-unlock.

Are you able to provide more details around this please.

I'm sceptical but at the same time I'm excited because this is how it should be for such a price.

Also how many credits did you need and what did you have done?

Hi, just want to clarify, is it possible to go back to my current (CLT-L29 C636) after rebranding to CLT-L29 C432? Is it correct for me to think-- to just follow the same steps outlined in the OP? If so, how about the OEMINFO part? Just want to make sure I get everything before jumping in.

[MENTION=2880355]dladz[/MENTION] - the guide/steps you provided said that if I am on firmware 120 and later, that I shouldn't try/use it. I am currently on build CTL-L29 8.1.0.128 C636. Does this mean I cannot debrand to C432?

My phone is already bootloader unlocked and rooted.

Thanks in advance guys! :)
[Huawei P20 Pro Guides, News, & Discussion] smbunn:
Didn't do anything at the echo step

I went through this process and was OK at every step, but my CLT-AL00 from China does not have an OEMINFO file.

I got to:

echo "--update_package=/data/update/HWOTA/update.zip" > /cache/recovery/command

echo "--update_package=/data/update/HWOTA/update_data_public.zip" >> /cache/recovery/command

echo "--update_package=/data/update/HWOTA/update_all_hw.zip" >> /cache/recovery/command

while in shell as SU and nothing happened. It returned to the shell prompt instantly. I then did the recovery reboot which takes me into TWRP.

What am I missing? I am trying to make my Chinese P20 Pro into a UK P20 Pro as the Chinese one is so locked down nothing works well on it

It was the same for me. In Twrp in did a factory reset and when the phone booted up it was rebranded.

---------- Post added at 12:24 PM ---------- Previous post was at 12:23 PM ----------

Now. How do I go back to CLT-L04 I want to sell my phone. Someone told me I could do a twrp restore but unfortunately I don't have one.
[Huawei P20 Pro Guides, News, & Discussion] MajinkenSword:
Exactly my question... I'm assuming it's:

1. Rebrand to your original stock (in your case, CLT-L04 - step on this thread only shows us how to go to CLT-L29 (C432))

2. Then reflash your stock firmware using the one from Firmware Finder or alternatives

Also, what version were you on before you rebranded? I am currently on 8.1.0.128 (C636). I'm thinking if I should rebrand and try RomAur. :)
[Huawei P20 Pro Guides, News, & Discussion] ysde:
Hello, I have been following op's and dladz's guide. I am stuck on this step copy and paste:

echo "--update_package=/data/update/HWOTA/update_all_hw.zip" >> /cache/recovery/command

mv *.zip /data/update/HWOTA and the respond I got: "mv: bad '*.zip': No such file or directory"

Hi,

I tell you what I did:

1. I re-branded my L09 to L29, but single sim, using the method "HowTo" in this thread. SW was 120, after re-brand 128

2. I bouth credit from FunkyHuawei (30 days full, just to make some trials)

3. I downgraded the rom from 128 to 120. Still no dual sim active, despite L29. Worked!

4. I used FHP20SingleToDual to enable the second sim. Worked!

5. I let OTA update from 120 to 128. Worked!

Today, I received the update message from OTA to 132, and I updated successfully, so dual sim works perfectly.

I suggest to use this re-brand method, and by just 5 credits for FHP20SingleToDual. The OTA will take over the rest.
