Convert P20 pro from single to dual sim - Huawei P20 Pro Questions & Answers

Hi all,
Is it possible to force flash the dual SIM ROM on the single SIM phone? Obviously assuming I can get the bootloader unlocked and without using the funky Huawei tool as it costs money as far as I understand.
Also if possible will then the phone receive rom updates via OTA?
Thanks

You can email them in the UK and they will give you a bootloader unlock code [email protected]

normal dual sim have 2 diferent IMEI , conversion via FunkyHuawei you get only one imei with 2 sim

thanks, having a single IMEI shouldn't be a problem as long as the two SIMs are hosted on different networks. (at least this is my interpretation).

Would an adaptation of this method work?

Effectively if we can change the oem info file to match the dual sim version then we should be able to flash the dual SIM firmware, right?

I see in another thread even if you do it the dual sim adapter doesnt fit in the single sim variant.

Thankyou

Hi all, any news on this ? just see here https://forum.xda-developers.com/hu...de-how-to-root-debrand-remove-retail-t3788326 that THERE IS NO HW POSSIBILITY TO CHANGE SINGLE TO DUAL SIM, SO EVEN IF YOU GO FROM L-09 TO L-29 THERE WILL BE NO DUAL SIM!!! NOT EVEN IF YOU PAY TO FUNKY
what is the reality ? I wrote to funky because on their site they say not usable with Emui 8.0.1 and I have a CLT-L09 8.1.0.128 (C432) fw installed - emui 8.1.0 Android 8.1.0, waiting for an answer:fingers-crossed:

CLT-L09 has same hardware as CLT-L29 can be converted to dual sim with FHP20SingleToDual, no problem.
CLT-L04 has different hardware and can't be converted to dual sim.

But once changed, where can I get the dual tray from? Any links from anyone who has done this mod? I'm sure I read that the official dual tray will not fit. Thanks.

Oh. Thank you. Emailed Huawei about getting unlock code for bootloader but nothing. Should I call them, or am I too late? I'm in the UK.

It is clear and no problem to get code. Now I think what to do with rebranding process...

Not true. One IMEI can manage two sim. You find The problem is in that countries where there is a sim-lock, like USA and Cina. This because IMEI is locked by operator. In Europe there aren't that problems !

Not true. But maybe you wrong understand. In first period there was no sim tray holder for P20 pro and someone (like me ) tested the sim tray holder of Mate 10 Pro. This works for both sim but it is too longer.
Now you can find the original sim tray holder of P20 Pro both from Huawei assistance and also from international resellers ( find it with google, like ali....)

I wrote many time in that thread : the RED sentence it isn't true ! With funkyhuawei method you can rebrand a CLT-L09 with single sim in a CLT-L29 fully working dual sim ! And I say this because I done this with my P20 Pro ! And many other poeple (for verified direct experience 5 people, but much more they said they did it). So I don't think that only few specimens of P20 Pro have a different hardware !!
I can say that all P20 pro have the same Hardware : both CLT-L09 and CLT-L29.
For your Last ask I must say that Maybe you read wrong because funky made specific tools for P20 Pro with EMUI 8.x.x . That info do you read is specific for older phone, like Honor or Mate

Did you read the rest of the thread? You didn't need to say he/she is wrong. That was from May and later people updated in June saying they did verify the dual SIM tray fit and works. Perhaps it was too early then that not many people knew and later discovered solution.

Just wondering if there has been any progress on this? I have rebranded from CLT-L09 to CLT-L29 and have purchased the official dual sim tray but the second sim will not get detected
Would rather not use the FunkyHuawei tool as it perma-locks the phone.

*Bump* - Can anyone please advise? I'd really like to convert my L09 to L29 to enable the second sim. I really don't want to use the funky method, due to serial change and bootloader re-lock etc.
Many thanks for your help.

New Huawei standard ROM + New SIM TRAY

Hey guys!
I got a whole New P9, EVA- L09. SIM Tray design is only for one SIM, and one MIcroSD.
My problem is, that I need dualSIM!!!
Is it possible to get a new ROM which is designed for EVA-L19, and then try to buy an SIM tray where I can insert 2 SIM CARDS?
Would it work?
Huawei Denmark says, that there is different ROMS, and I need to get a new ROM.
Please help!

I'm not a Dev but that's from the eva-l09 build.prop.

this is not possible as the phones hardware itself is one nano sim and 1 micro sd card. changing the rom and sim tray will only brake a perfectly good phone
next time i would suggest checking this detail before buying the phone

Firmware version for BL029 BL Unlock

Sorry guys, but I'm still confused about which FW versions can be BL unlocked and which can't.
I'm not familiar with the Huawei versioning in the naming of the firmwares.
Specifically, it's BLA-L29 8.0.0.150 C432 that I am wondering about. If someone feels like explaining the versioning in a sentence or two (or point me in the right direction), that would be really appreciated.
Thanks!
In one of the other messages treads some posted this link.

It was Quoted from this thread finally-unlock-bootloader-mate-10-pro-t3850111
I think the version system is different from how you listed. Some people talk about the 8.0.0.xxx With xxx being some thing 142 or 145 but the guides mostly use C432 and c636 for example. This C number you can see on the about software page in you phone as well as the xxx. It usually appears after the version like, 8.0.0.xxx(Cyyy).
The part I'm struggling with is that I have a two sim phone, BLA-L29 and most people her are loading BLA-L09 (single sim version) of software. i don't know if its compatible. I think they are as I've never seen an issue with any other phone in the past. People use to use the dual sim add on's and you never had to update the software to recognize the new sim tray. So I think I can load BLA-L09 but I'm not sure. Still doing my homework.
Thanks, I think I got it figured out now.
According to posts here in the forum, the unlock is not possible from versions >= 8.0.0.145 (which can be downgraded to ...142).
What wasn't clear to me, was the way the versioning works. But apparently it's simply counting up, so 145 is a later version than 136.

C432B142 is the last firmware where DC worked (for C432, other custs have other build numbers). B145 can be downgraded to B142. B146+ use new bootloader which can't be downgraded. So on B150 you will not be able to get an unlock code. I did however see some site which claimed it could get unlock code for any firmware, even on new devices. I'm not sure how reliable it is though and it cost €30

Just to clarify. BLA-L29 8.0.0.143 (C636Patch1) would be B143 so I can downgrade? This is the first time I'm seeing Bxxx.

I saw the post about the 30€ unlock in the P20 forum. The guy said he got his code very fast and it worked - I do find 30€ to be a bit steep though.

BLA-L29 8.0.0.143 (C636Patch1)
Edit: If I had to guess, he has access to the tool they had hooked up to the website previously. I have a dual sim phone so he needed the IMEI of the first sim slot. That is the on on the sim tray and the one listed on top in the software.

Yes
30 euro is price

UNLOCK bootloader app confirmed working (Not free though) for the Mate 10 / Pro

Not sure if people are aware of the app DC Huawei Bootloader Codes, but I've just unlocked my Mate 10 ALP-L29 using this app, there are 2 options, a cheap £3 one, which does not work on Android O firmware and the expensive, around £23, which gets the bootloader unlock code from the phone's IMEI, so had a go at it and not even 2min I got an email with the bootloader code and confirmed working, running Android Pie from the OpenKirin team and so far all seems to be working great, so good to be back to stock Android...
Just thought I would share my experience in case someone was not aware of this great app.

Not 100% sure, but it's based on IMEI, so I would say it should be fine, I know the app asks a few questions, but I assume is just to cover themselves... I know it's a bit expensive, but if you're fed up of EMUI it's a risk worth paying, it's like having a new phone

Did your IMEI / SN change?
Most probably it did, unless you used a rebranding method that I'm not aware of.
In this case this unlock code will not work.
Done on a dual sim version.
I send the first of the 2 imei (as seens in the infos) and got my unlook code in 5 minutes.
Unlocked now and use openkirin OmniROM Pie Alpha 2
Working great so far

still not supported by devices 8.x and above
that is, if I officially upgrade to emui9.0 something me will be available cheap option?
I've just bought a new Huawei Mate 10 Pro and haven't upgraded it in order to be able to unlock its bootloader. The build number is BLA-L29 8.0.0.120(C432), could I unlock it using the cheapest option (instant read bootloader code from phone) ? There are conflicting information on DC Unlocker's website.
Thank you !
Edit: I managed to get a code with the cheap option as I have an old build number on my device !

If it changed the IMEI number then you probably have a phone with an invalid IMEI number as a result, and one that will not function on the majority of carriers. The IMEI number is the actual identification used when the phone communicates, just like with network MAC addresses, no two devices can be active with the same number at the same time.

CLT-L09 C432 Dual Sim

Hey guys, is it normal for a CLT-L09 C432 to show as dual SIM? I only have one IMEI where as I know dual SIM phones have 2 IMEI numbers.
CLT-L09 is single sim. Looks like the phone you have has been flashed with the firmware that was ment for the CLT-L29 .
