Not so far as I'm aware, I've just seen that all the majority of people are doing the same thing and it's probably best to be a part of that, i mean if a certain ROM, treble or otherwise requires it then I'd prefer to have It.

Other than that no.

Have noticed the phone seems to be smoother and perhaps a little more efficient.
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
This is because you flash twrp recovery instead of nocheck rexovery from the manual. Flash nocheck recovery and follow the steps again
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
Yes it will work
[Huawei P20 Pro Guides, News, & Discussion] colthekid:
Actually, thinking about it, why are we bothering to edit the oeminfo?

Wouldn't it be easier, and safer (no errors in writing the command) to just have a thread with copies of the various oeminfo for all varieties of the p20+?

That's certainly what we did back on the P9
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Sounds like a plan..or would it be better if we were all on the same variant so if something works on one then it'll work on all of them?

---------- Post added at 02:50 PM ---------- Previous post was at 02:29 PM ----------

Lol work as in revert back to L09 or just restore L29 as it is now?
[Huawei P20 Pro Guides, News, & Discussion] colthekid:
Don't think everyone would want to be on the same variant (I have no interest in dual sims for example, so I'll be staying on L09)

Just need one of each variant & region (L09C432, L29C432, L09C782 etc etc...) then people can take their pick.

Just need to know how the OP backed up the Oeminfo he provided, via TWRP or ADB?
[Huawei P20 Pro Guides, News, & Discussion] :
If everyone was on the same variant none of us would be having these issues now. There only needs to be a chinese and internation variant. Thats it.

For some reason huawei wanna go uk, eu, canada, mexico, then a few versions for china alone, then...I dont know there must be about 20 model numbers minimum
[Huawei P20 Pro Guides, News, & Discussion] oriveradel:
great guide, just about to try, but I need clarification on step 2, how exactly you flash patched ramdisk magisk.img , do you flash in bootloader as a recoverY?
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
I've managed to do it! Rebranded to CLT-L29(C432)! Thanks so much [MENTION=2880355]dladz[/MENTION] [MENTION=1176451]colthekid[/MENTION] and [MENTION=1599044]ToLive4[/MENTION] as you helped answer all my questions and get me to understand the process!

Is it safe to take OTAs now?
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
Yes it is
[Huawei P20 Pro Guides, News, & Discussion] ToLive4:
Flash it via fastboot after you unlock bootloader
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Awesome! Is there a way to pass safetynet or do we need magisk for that? I get basic integrity as true but CTS is false
[Huawei P20 Pro Guides, News, & Discussion] doromax:
Hi, Is your phone dual-sim now ? Can you say me if all the two sim works ?

Can you see the dual-sim menu ?

Thanksss
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
So I can see the dual card management setting as in the screenshot. If I try disable SIM card 2 it says 'failed to disable SIM card'. I also don't have a dual SIM tray so can't test.

This is as much as I can see/inform about dual SIM having just done the conversion. I don't know if anyone has managed to test if a second SIM would work
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Yea mate that's the problem. If you have multiple variants you end up with one bunch of people getting nothing and another getting lots, causes problems.

Centralising everything is a good step in the right direction.

Each to their own

AFAIK the most common and wanted variation is.

L-29

C432

128

If a ROM is made it'll more than likely be on that.

Problem is we have err 2 ROMs.

:eek:

---------- Post added at 06:30 PM ---------- Previous post was at 06:29 PM ----------

Have you updated it?

---------- Post added at 06:30 PM ---------- Previous post was at 06:30 PM ----------

No probs man. Welcome to the sunny side of things. :laugh:

Think for OTA you'll need the stock recovery.

Not sure if root has any impact. I've got an update pending.

There's a possibility to update via recovery, theres a thread in guides
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Yeah it's nice to be back in the game. Didn't think I'd bother rooting my P20 Pro. Only last 1 month haha.

So I'm fully stock and on 128 after doing an OTA. But fail safetynet. I think the unlocked bootloader trips it. Do you pass safetynet?

Have you got an OTA pending for 131?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Omg lol no, there's a full ROM for 120.

Are you taking the 131? I'm really unsure of myself on this phone, I've literally had HTC since the G1 with the odd anomaly here and there.

Lumia, S3, S5, Note 4, Z1, 1+5 , 6P

But this thing is mental, the variants are just overkill, no idea why it's like this.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Got another update for the ROM I'm on? Guess I'd get 131 next if you've got it offered.
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Wait what were you saying no to? Passing safetynet or have an ota waiting to go to 131?

Are you still on 120?

Edit: Just saw your edit, is that the ota being offered to you? Aren't you already in 120 as that's the ROM in this thread?

Edit2: I don't have 131 as an OTA yet, I think you can get the whole ROM and flash with HuRUpdater though if you've got TWRP
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
dont bother to buy dual sim tray. today got mine then convert to l29 guess what nothing. software shows dual sim menu but u cant enable or disable anything, even with 1 sim u cant change anything. So then i put sim only in tray 2, it even dont detect that. i'm pretty sure l09 shipped hardware not capable for dual sim.
[Huawei P20 Pro Guides, News, & Discussion] sudman:
Do we know yet if you follow this guide you can return to stock? i.e. go from CLT-L09 C782 to CLT-L29 C432 back to CLT-L09 C782.

What I would actually like to do is rebrand my phone to CLT-09 C432 is this possible using this guide? I have no interest in going dual sim I just want the EU variant so I can frequent/latest updates, and be able to go completely back to stock so i can sell the phone easily.

*Edit* according to firmware finder there is a CLT-L09C432B131 full OTA but if I flash the CLT-L29-MAGISK.img will that **** things up? Can you get a CLTL09-Magisk.IMG?

Ahhhhh so many questions...sorry but this is doing my head in & I dont want to brick this phone.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
I wouldn't downgrade, one of the guys here did it and ended up with a brick.

It's probably possible but I wouldn't.

---------- Post added at 02:01 AM ---------- Previous post was at 01:59 AM ----------

Ah ok.

An yea it's offering 120 even though I'm already on it?? No idea mate.
[Huawei P20 Pro Guides, News, & Discussion] suicidal.banana:
Im already on a CLT-L09 C432 with 8.1.0.128 firmware (which seems to be what everybody is aiming for with this thread?) so was really just looking for the dual sim details, but ill keep looking :P (also sry for the late reply)
[Huawei P20 Pro Guides, News, & Discussion] dlads:
The dual SIM model is L-29 AFAIK.
[Huawei P20 Pro Guides, News, & Discussion] sudman:
Mate, in your guide why do you state that having TWRP is a pre-requisite. I cant see you using it any point or is just becuase you want if at a later date? Am I right in thinking that the original guide doesn't install TWRP. Or am I missing something and just being being dumb? :)
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Because you're flashing magisk as per the guide and the one in the guide although I'd never change it is out of date.

With that in mind for future flashing you would need twrp, unless you used images.

Obviously if your intention is to return to stock (and I've no idea why anyone would if they're going through this guide) I guess after the guide is complete you can leave it as is
[Huawei P20 Pro Guides, News, & Discussion] sudman:
Thanks, think I've understood. Reason I'd be wanting to go back to stock is when I come to sell the device. Sell as stock and then theres no warranty issues etc.

But am I correct in thinking that the original guide doesn't require twrp?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
That's correct.

However if you are rooted then you'll need to update magisk.
[Huawei P20 Pro Guides, News, & Discussion] sudman:
Thanks for the mate, cool, so final question then hopefully, so if I follow your guide, will I still get OTA updates and can I install them if I have TWRP installed. Because it used to be that if that was the case then no you couldn't install OTA updates, you had to wait for system images to flash via TWRP when you wanted to flash the latest update.

Sorry for all the questions but rather new to Huawei devices and haven't played around with debranding and flashing new devices in a long time.

Cheers

Sud.
[Huawei P20 Pro Guides, News, & Discussion] doromax:
Hi, I'm sorry to contradict you but the hardware of the L09 model is the same as the L29 model, so also the telephone part and the ability to manage 2 sims!

As I wrote many times in the various threads here in XDA, I bought an L09(C432) model from an Italian operator (Wind). The phone was not branded and had the sim-cart (sim tray holder) with a single place for the sim (mono-sim).

I use the funkyHuawei method and Now I have a model L29(C432) with both 2 fully functional sims!

The problem for the dual-sim is inside this method.

FunkyHuawei change the bootloader and both 2 sim works flawlessly. This method mantain the original bootloader and so only one sim works !

Infact with funkyHuawei after the procedure your phone have the bootloader blocked again and you can't use anymore the Huawey key to unblock it.

My goal was to have 2 sim full functional. And I got it !

If your goal is this you may use only (for now) the FunkyHuawey method. If your goal is a new firmware or other you can use this great method, also without spend your money :)
[Huawei P20 Pro Guides, News, & Discussion] sajibcy:
Thanx for correction. as my phone was ee branded probably thats the reason as you are saying yours working fine so no hardware issue. probably someone will come with new method for working dual sim. funky just expensive and bootloader locked for now. but thanx for your info.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Lol I'm in the same boat, I had 120 pending which strangely is what's installed, which I took but thought it failed.

Now 128 as an update is listed, but after trying, it hasn't installed and 120 is installed.

I have never on any phone (android) since the G1 took a single OTA, not one, they usually break root or something else and I've always had a ROM ready to roll.

If I had to guess I'd say you require the stock recovery as it opens up TWRP when I attempt the installation.

I'm be removed security but it's made no difference.

Where's the stock recovery.? I'll test it now

---------- Post added at 09:17 PM ---------- Previous post was at 09:14 PM ----------

Please don't recommend the funky method, least of all in here.

FYI if you plan to have your bootloader unlocked again, do not perform the full de-brand from funky you will not be able to unlock your bootloader again..

It is terrible advice to give anyone on XDA, the fact that they're charging people for it is disgusting.

No more of that crap in here please.

Using our method is safe and free, as per the OP you won't be getting dual SIM but your bootloader will remain unlocked which is what most of us want.

Maybe there's another way but not yet.

Funky are heading for a law suit, I find it astonishing that they've got people to pay and then not warn them enough about the bootloader.

Anyway I'll leave that conversation for the funky thread.
[Huawei P20 Pro Guides, News, & Discussion] sudman:
Haha, :)

Well if you could update us with the results asap I'd be grateful. All I wont to do is get much needed updates on this phone as 110 is absolute bollocks for me. Dont want root, dont want TWRP, just want updates to see if it'll sort my issues out. These are namely poor blue tooth, random app closures, power management that seems to ignore my manual settings and poor battery life when blue tooth device connected.

Basically I just want a standard CLT-L09 432 not the CLT -L09 782 that I have that Vodafone/Huawei seem to be very slow allowing updates.
[Huawei P20 Pro Guides, News, & Discussion] navalynt:
I've done the rebrand from C605 to C432, then updated to firmware B131 and also installed Magisk 16.4. Root works (of course) but I cannot get it pass SafetyNet due to ctsProfile.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Hmmm will have to look at that.

Mines alright but I've got to update.

How did you update the firmware? Did you take the update or HUR method?
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Have you gone through one of the guides? Here?

You'll end up on 120 and c432 L-29 think there's a way to remain on L-09

If you don't then you're at the mercy of the 782 variants updates afaik.
[Huawei P20 Pro Guides, News, & Discussion] sudman:
Yeah been through both guides and with your answers/help I'm pretty sure I have a good understanding of what I'm doing & why. Now I just need to bite the bullet and pull the trigger:D.

Basically I'll follow mostly ToLive4's guide but referencing your more detailed instructions & commands, I'll change the oeminfo file to read CLT-L09 C432 hw/eu and replace your update files with either the 128 ones or 131 which I've downloaded via Firmware Finder (for CLT-L09 C432) . Then once all done I'll re-lock the bootloader. Hopefully that should get my device to where I want it to be and allow me the option to return to to stock at a later date if the 782 firmware release schedule catches up so I wont have to downgrade the firmware and thus hopefully avoid the possibility of bricking the phone.

Well that's the plan anyways. :p
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Can't recommend deviating from the original guide but that's not to say it won't work, which i hope it does.
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
I seem to remember reading in the B131 thread people were failing safetynet and it takes time to pass or something. Maybe when Huawei OTA the firmware. I pass safetynet and I'm currently on B128 and have Magisk

HUR method. If you're on 128 can you send me your build fingerprint? Use this command: getprop ro.build.fingerprint
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Installing OTA's after de-branding

Just updated my phone through the various updates and seeing as no one had actually mentioned it i thought i'd do another little guide just to help people out.

After you've gone through either the guide in the OP or https://xdaforums.com/showpost.php?p=76785704&postcount=152 you'll probably have re-rooted and installed TWRP.

*NOTE* You do not have to uninstall TWRP or install the stock recovery, nor do you need to unroot.

Please read through prior to committing to the guide. ;)

1. Go here https://drive.google.com/drive/folders/1oWS92OT0Bt2bFktwNCIKLsogA8L50g57 and download the file called recovery_ramdisk_nocheckP20.img

2. Connect your phone to your computer (make sure USB Debugging is on)

3. Put the img file in your ADB / Fastboot folder (my default is C:\adb )

4. Open a command prompt / powershell from your ADB/Fastboot folder.

Type: adb reboot bootloader

PRESS ENTER

5. Wait for the device to boot to the bootloader (white screen)

Type: fastboot flash recovery_ramdisk recovery_ramdisk_nocheckP20.img

PRESS ENTER

6. Type: Fastboot reboot bootloader

PRESS ENTER

7. Disconnect the phone and allow the device to boot up.

8. Once the device is booted, take the update and allow it to fully install.

NOTE* Not sure if it's completely necessary but i did it anyway, disabled all PIN / Password / Fingerprint prior to performing this.

After the installation you'll have no TWRP and you won't be rooted so if you'd like to go back to the way it was.

Follow the guide in the OP to get TWRP and root back.

Hope this helps. :D

I took a guess what the fingerprint would be for 128 (because all that seems to change is the version number):

HUAWEI/CLT-L29/HWCLT:8.1.0/HUAWEICLT-L29/128(C432):user/release-keys

Instructions for using the C432 128 firmware fingerprint with the 131 update and passing ctsProfile check in Magisk Manager:

Within Magic Manager install a module called MagiskHide Props Config

Reboot device

Make sure you've turned on USB debugging, and I've found that enabling Allow ADB debugging in charge only mode makes the connection with Windows 10 a little more stable

Open a command line and type in: su

Accept the root request from Magisk

Now type in: props

Select option 1 to "Edit device fingerprint"

You'll be at a prompt that says "Enter 'e" to exit:" Copy/paste the build fingerprint above into the prompt.

Hit enter, then press y for yes to reboot

YOU'RE NOT DONE YET, wait for phone to reboot

Open a command line again and type in: su

Now type in: props

Select option 5 for "Script settings"

ONLY if option 1 says "Boot Stage (late_start) do you need to complete the last few steps below

Select 1 for "Boot stage"

Make sure the window says "Current boot stage is late_start. Do you want to change it to post-fs-data?"

Enter y and then enter, the same for rebooting

Once you reboot you *SHOULD* pass the ctsProfile check in Magisk Manager. This post should also be adaptable for future firmware upgrades after you've debranded and are on C432
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Sorry the Hu updater method? Think you get it from firmware finder then there's a guide on one of the threads here so you can install from recovery, i personally don't need that method now, just took the OTA update, all you need is the nocheck recovery_ramdisk here, which i've just made a guide for :)

I'm just re-rooting to check if i pass safety net myself, i dont' have 131 advertised to me just yet so can't comment on that firmware but i'll give you the output for 128 now.

Yep it's still passing safety net and my fingerprint is all good.

Didn't run through that guide as wasn't required

getprop ro.build.fingerprint

dladz, you sir are a gent, and so is ToLive4.

Thanks very much for all your help.

Next I'll try relocking the bootloader and see it it'll take OTA's or I'll have a look through your later guide more throughly and decide the best course of action.

Cheers Mate

[Huawei P20 Pro Guides, News, & Discussion] dlads:
Haha nice one fella, enjoy.

If it were me I'd have it rooted and modded, cannot abide adverts or bloat so for me that's worth it just for that alone, then of course you've got magisk and it's many mods.

Swap torpedo is my new favourite, it just makes the whole phone so smooth with no loss of battery life.
[Huawei P20 Pro Guides, News, & Discussion] sudman:
May still go down the rooted & modded route but first I just wanted to see how the rebrand went & get a feel for things as it's been a while since I've done this sh!t.

As you said previously doing things this way, rather than the wonkyHuawei way, I still get to keep the freedom to unlock the bootloader, potential do what I like and have enough money left to buy beer!

At least I've got updates for now so we'll see if that changes my view of the phone and what I do next.

Thanks

Sud
[Huawei P20 Pro Guides, News, & Discussion] doromax:
I completely disagree with what you wrote and especially with the words you used. Here in XDA we talk about development and the method described in this thread by @ tolive4 fails to do what the Funkey method does. That is to have 2 fully functioning sims.

I agree with you that asking for money to change software is not the best, but they ask and it's up to you to decide. Nobody is obliged. And talk about crap as the lawsuits you personally know (only you though) does not seem to me clever. There are several methods and it is right to talk about all these methods. I have written a thousand times, even in proven, that the model l09 and l29 have the same hardware but the OP of this thread continues to leave written in large blocks that are different hardware and that will never work the dual-sim. Is not it true but why should I offend the OP or tell him not to talk about this anymore?

And as for the bootloader those of Funky have always said clearly that after the procedure will remain (for now) blocked. So we do not talk so much to talk.

sorry but who says that most users want to change the phone from l09 to l29 but do not care that the two sims work? for me it is pure madness. Do you want to convince us that if one buys a 4-cylinder motorcycle, it's enough for him to work 2?

[Huawei P20 Pro Guides, News, & Discussion] dlads:
Sure everyone knows that their method provides you with the only way to utilize both SIM cards which I agree they do, however it also makes the device (for MOST people) a paperweight, with no ability to unlock the bootloader etc they wouldn't want the phone, I'm in that category as are many others.

Nothing is going to change in that regard and I imagine from the prices I've heard that they've earned thousands.

You have to understand, funky are a paid for service, if Netflix broke your fire TV forever but converted your device to something some people like you'd send it back? Haha but this is different? Hmm.

Funky method if replicated will break your ability to unlock your bootloader, they have not declared this in the correct way, I do not want to talk about this at all with you, if you need to vent then please feel free to PM me, I don't believe funky deserve the time to be talked about on an open forum and they have a thread for that on XDA already which I'm sure they'll be happy to hear your positive view.

I've managed to re brand to CLT-29 thanks to the guides. I'm now on CLT-L29 8.1.0.128(C432).

I've used the com.topjohnwu.magisk_5.5.2-84_minAPI21(arm64-v8a,armeabi-v7a,x86,x86_64)(nodpi)_apkmirror.com.apk Magisk file. It asks me to update to 5.7.0 version. When I do this the app won't load. Is this a know issue?

Also can't use Android Pay as it knows my phone is rooted :(
[Huawei P20 Pro Guides, News, & Discussion] SpH1nX:
Yes, it's known. Just don't update and it'll work just fine.

Regarding Google pay, do you pass the safetynet check? I've no problem at all
[Huawei P20 Pro Guides, News, & Discussion] adieSA:
I'm having the same "problem" as others. I've converted my L09 to L29 and when I search for dual Sim management under settings it shows the dual Sim option with Sim 2 being inactive. I ordered the mate 10 pro Sim tray because the P20 pro Sim tray wasn't available yet. It still only recognised the 1 Sim card. So I'm not sure if it's a matter of using the wrong tray or if it won't work regardless. Will order the P20 pro tray and try. Annoying because it takes 2 months to get to me.
