Shouldn't make an difference to VoLTE

---------- Post added at 10:05 PM ---------- Previous post was at 10:01 PM ----------

Might have noticed a bad limitation for rebranding.

I was originally on the L-09 782 and I rebranded like many of you to L-29 432

Now when I'm trying to install Treble ROMs they reboot after about 9 minutes, even after a format, complete wipe of every partition, another format and an eRecovery.

Treble ROMs still reboot under 10 minutes.

Someone else who has the same model number ie: L-29 432 but did not need to rebrand, he does not have reboots.

We've looked at everything I know to change but can't find out why, were thinking it could be ramdisk or at least a part of it. So just beware that if you rebrand, you could also have this limitation..

I'm sure it can be fixed but at this point in time, I cannot for the life of me find out what it is.

Could be you have to enable it in build.prop if you have root.

its not rooted so there is any secrets code to enable like hidden menu i can enable it

i just rebranded my phone back from c432 to c185 just for testing and everything went good.

what i did is that i had full twrp backup of my old c185 firmware.

i restored my backup than directly flashed c185b130 firmware with hurupdate,after that i did a factory reset from stock recovery and the phone booted normaly.

just wanted to share this for people who want to rebrand back to their original region.

Is there any way to lock the bootloader to locked stats not relocked?
[Huawei P20 Pro Guides, News, & Discussion] gm007:
No one know if it's possible to change the bootloader status from relocked to locked and how?
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
is any one able to recover via erocvery or hisuite? i was trying to do today after 83% download package failed then tried with hisuite ,system unable to recover contact nearest service center. i wonder why! i rebranded mine from uk (c745?) to c432.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I've ran eRecovery several times without issue.

---------- Post added at 01:38 AM ---------- Previous post was at 01:35 AM ----------

Has anyone who's rebranded tried a treble ROM recently?

Is someone able to test please? I think the prices breaks treble functionality.

Need to find out why
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
Thanx. tried after several times but always stuck in 83% even after factory reset. is thr anyway to return l09 version from l29 as dual sim is not working anyway?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I've only heard of one guy who tried this and he bricked his phone.

In all fairness i'd like to do the same as treble rom's would begin to work for me.

Plus the updates which i thought i'd benefit from are so minor in what's been changed i wish i hadn't bothered.

Personally i wouldn't try to revert back, but it's your call.
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
thanx. looks like no choice. def dont want to brick phone. great phone but with lots of difficulty. even in samsung u can get away most of the things with odin.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
What firmware are you on?

If you go from 152 or 156 and then back to a low firmware it can cause problems, in theory if you're going from one firmware to a higher one whilst rebranding then you should be ok.

But I would clarify and check everything before committing
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
im on 152. i dont want to take risk lol better leave half cripple. its not that its creating any trouble, its just middle of 2 version. guess i cant use even funky to convert. from l29 to l09 ( when it is actually l09) or l29 to l29?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I wouldn't use funky at all, you may lose your ability to unlock your Bootloader, I don't know too much about it to be honest so have avoided it.

Best to ask them tbh
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Has anyone actually managed to go back to their original model? Ie: L-29 back to L-09 782 to 432 ?

I only ask as I think this is why treble ROMs aren't working
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
do u think of ots possible to go from l29 152 to l09156 using this same method?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I'm really hoping so cos I've had enough of this rebranded crap.

If it's the reason behind the not working then I really want to get it done. Otherwise this phone is dead to me.

I'd like to use RR and Omni
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:

[Huawei P20 Pro Guides, News, & Discussion] dlads:
I was L-09 782 unfortunately.

Do you think it'll matter.

In all honesty all I want is to be able to flash treble ROMs. I don't care if it's L-09 or not

---------- Post added at 08:56 PM ---------- Previous post was at 08:55 PM ----------

What did you do? I'm on

152 L-29 432

Used to be

110 L-09 782

Might try the L-09 432 it's worth a shot.

But I think the 432 is maybe what's doing it

If you can relay what you did. Maybe even point me in the direction of the files used id appreciate it.
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
I just downloaded 156 rom (approved for l09) with firmware updater and in oeminfo type l09 c432. Rename as your debrand guide. And follow your guide. That's it. I guess if u want to move uk version probably better to select 156 equivalent rom for c782 and type correct oeminfo for c782.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
So HURupdater method and then once booted, reboot back to Fastboot and OEMINFO flash?

*I would need 156 you're correct, as i'm on 152.
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
hi. i didnt did HURupdater. i followed yours debrand guide. https://xdaforums.com/showpost.php?p=76785704&postcount=152

what i did is i download 156 firmware (approved one. i think 91 ending changelog) then just rename as your guide. using your oeminfo,

instead of Type: ./oeminfo CLT-L29 C432 hw/eu , i typed ./oeminfo CLT-L09 C432 hw/eu . thats it. no error no boston chipset.

156 is for c432. if you want move uk version i guess u need similar version which is higher then 152.

As far as I am aware, currently you cannot flash any software with locked bootloader, you need to be unlocked. Sucks :(

[Huawei P20 Pro Guides, News, & Discussion] subhani:

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

I'm new to Huawei devices modding/rebranding so maybe I missed (or messed up) something with the procedure to rebrand from my CLT-L09 device to CLT-L29.

So my situation is the following:

I followed the guide and "successfully" installed the CLT-L29 firmware but now i'm getting chipset-boston 8.1.0.001 (01F4) in the build info.

The previously installed firmware was CLT-L09 8.1.0131 (C55patch01).

How can I solve the chipset-boston issue? If I have to re-do the rebranding procedure is there something that I need to change or be careful to do?

I tried to read the boston chipset issue in the posts, but I have not understand much.

The only thing I understand is that the problem is caused by the oeminfo and it has to be modified according to the previously installed firmware.

Any help would be much appreciated, Thanks.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
AFAIK it's oeminfo that causes this

Although if you search this thread you'll find others who have had this issue.

Personally I'd just run through it again.

Don't want to bother you dude but just wondering some stuff. I'm on 131 so is debranding a no no from L09 to L29? Do I even need to debrand or is it possible just to root?

I'm coming from a long line of Xperia's and never bother with Magisk before so this is all new to me, probably shouldn't be trying it at 3 in the morning!
[Huawei P20 Pro Guides, News, & Discussion] dlads:
You can use the guide. But the files you'll need will need to be later versions than the one you're on.

For example you're on 131 L-09 so it's say get 152 for L-29 .

As there's so many I've not obtained the files for people.

But you're right not to have attempted it, you could have bricked.
[Huawei P20 Pro Guides, News, & Discussion] fatguy666:
Well, first I want to say thank christ that's over! Been at this for 4 hours or something.

Bootloader code I got from ministryofsolutions worked no problem in the "TOOL ALL IN ONE". Things went downhill from there. Fastboot was recognising the device but wouldn't let me flash TWRP, kept getting "write to device failed". After 20 minutes mucking about with drivers I took the cable out and put it back in and it worked.

Magisk installed fine so then on to updating the ROM - changing from CLT-L09C783B133 to CLT-L09C432B159 (8.1.0.159). Files just would not copy over to the phone, device would disappear after about 5%. Eventually this was solved by digging out another USB cable I had, turns out the cable that came with the phone is good for charging and not a lot else.

After HuRUpdater had done it's thing and the system booted up I was greeted with the "chipset bolton" issue. I figured doing the oeminfo bit would fix that and it seemed to go according to plan. Unfortunately, the phone ended up in a bootloop - would show the A from HUAWEI in the shiny bootscreen then reset and go into TWRP. After panicking for a bit and looking for a solution I did a factory reset in TWRP which sorted it, phone booted up.

HiSuite has finally restored my apps after what seems like an eternity and everything is working order, only thing missing is my widgets.

I've wrote this out partly for myself but for anyone else having issues with this. I'm not a total n00b when it comes this stuff but I think if I'd started out using my other USB cable I'd have been done in 1/3 of the time!
[Huawei P20 Pro Guides, News, & Discussion] fatguy666:
One other thing, I went to the shop last night and forgot my bank card and had to put all the stuff back so thought today I'd set up Google Pay.

It's such a shame that the thing which should be free, we have to pay for it.
[Huawei P20 Pro Guides, News, & Discussion] gerald.mrrsn:
Hoping someone could answer a few questions, would be greatly appreciated :)

I'm so glad i got my awesome 256gb P20 Pro unlocked lastnight thanks a bunch to ministryofsolutions.com (much cheaper then FunkyHuawei), even though i had to pay $45 Canadian bucks, it was totally worth setting my baby free once and for all :D

But one thing I've found out right away is that Huawei is F'n complicated, this is my first phone from them, I'm coming from a long line of flagship Sony phones, and before that a long line of flagship Samsung phones and they were all easy to manage compared to Huawei, whom so far has just been giving me a headache haha

so for the questions, cause i don't wanna end up with an expensive BRICK, i was hoping someone with their special Huawei knowledge could tell me if its possible to rebrand my 256gb Chinese CLT-AL00C00 P20 Pro on the newer 8.1.0.171 update to the international version or at least some other version which doesn't have all the Chinese crap throughout the firmware???!!!

And if it is possible to rebrand my model with the current update that i have, would it be possible to rebrand my phone AS IS, OR would i have to downgrade my phone to 8.1.0.120??? OR is it even possible at all to downgrade my phone from the newer current update that i have to the .120 older firmware??? Cause I've seen others say it was dangerous downgrading to a older firmware from a much newer one cause of the xLoader or whatever, as i don't know if my current firmware has a newer incompatible xLoader then the older .120 firmware!!!??? I've read lots but not all of this thread since there is 60 plus pages, plus I've been through plenty other forums and such from other sites etc etc and I've never really found the answers i was looking for, I've seen few people on here and elsewhere say they successfully rebranded there Chinese P20 Pro but they never really specified what exact model they had or update they were on and if they had to downgrade first or not and if they had a 256gb version or not (i don't know if the size matters???)

So I'm hoping someone out there could help me out, you'd be a life saver as i really wanna get this rebranding over and done with so i could finally start modding my phone :P :)

EDIT: this is what FunkyHuawei says on their P20 Pro rebranding page;

Warning: If you are rebranding Chinese to non-Chinese (AL00 to L29 for example) and your phone has a recent firmware installed, you should downgrade to a lower version before trying this. There is danger with recent firmware versions, going from Chinese to international. Contact us for details. If you proceed and render your phone inoperable without regarding this, it is your responsibility and we cannot refund your payment. Be careful!
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I'm the same as you, Huawei are a mess when it comes to rooting etc.

Personally I wouldn't use funky, they're expensive and with certain services they offer I believe it's your serial number that gets altered so if you relock your bootloader then you won't be able to use the same code you've paid for.

That being said the process in this thread whether the OP or the one in my sig isn't too hard.

I would avoid downgrading, some people have done it but some have ended up with a brick.

Bare in mind that you would need to obtain the same files in this thread for what you want to rebrand to, don't use the files here unless you're on a firmware lower than 120.

As you're on 171 you'd need the same or higher OR take a chance downgrading.

Stop there if that's all you need

But in all fairness none of that matters if you want custom ROMs.

You've unlocked the bootloader (great that's the hard bit)

Download and flash the unofficial TWRP recovery listed on the p20 development section.

Once installed visit the Honor view 10 forum

Go to their development section

Download AICP

Download G-Apps

Download Magisk 16.6

Download the P20 Pro 131 camera zip.

Copy them all to your phones memory.

Whilst in your phone, remove your pin, password, fingerprint (twrp can't see content unless securities are removed)

Boot to twrp (vol up and power)

Full wipe

Flash ROM, G-Apps, magisk and p20 pro camera in that order and in one sitting without rebooting.

Boot to system (it'll loop once, allow it to boot)

Set up phone

Done.

Not working

-------------------

NFC

Stereo

Fingerprint gestures (fingerprint works)

You also have Treble ROMs.

If everything falls flat and you can't boot.

Boot to eRecovery and go back to stock, your bootloader will remain unlocked.

Lastly, if you're not wanting a custom ROM and you just want to be rooted in EMUI or a custom EMUI ROM then you can either not rebrand (little to no point anyway seeing as you're on the latest OS.

As for custom EMUI ROMs, there's only one, which is closed and only went up to 131 which would mean you would have to rebrand.

My advice.

No root -stay where you are

Root (EMUI) - install TWRP, install magisk

Custom ROM - perform the steps for AICP ( best one at the moment)

Hope this helps.

- Change ./oeminfo CLT-L29 C432 hw/eu to ./oeminfo CLT-L09 C432 hw/eu

I also got error saying "No SD card or USB device please connect in 2 minutes!" during factory reset but everything went well.

I only did this 1 hour ago so I am still finalizing applications installation/configuration.

[Huawei P20 Pro Guides, News, & Discussion] dlads:
The bootloader remains unlocked.

Root access is obtained by flashing magisk on twrp regardless of root status.

Bare in mind, flashing pie will break twrp so you must fish magisk before you leave twrp for the first time.

Pie is only in beta at the moment. Bootloader being unlocked will give you a window to fix your phone should something go wrong.

If your relock it will simply state RE-LOCKED so if it was me, I wouldn't bother locking it..
