I used method 1 and the 29 ROM from here.

---------- Post added at 07:38 PM ---------- Previous post was at 06:57 PM ----------

I'll attempt a guide here that's maybe not the quickest way of doing it but it's the way that works for me. The guide also assumes you can manage to download a quick adb setup and use adb from the command line. Bear in mind that BadWolfYe has written guides on what I'm about to cover below and that's how I learnt. TWRP install by BadWolfYe.

0) Take working L09 phone and bootloader unlock code (I put the details of my phone into the Huawei website and got a code in return)

1) Enable developer options by going to Settings>About phone and tapping 'Build number' a bunch of times until it says you have enabled developer options.

2)Now go to Settings>Developer options and select 'enable OEM unlock'. Also enable USB debugging and ADB etc.

3)Download and rename twrp to twrp.img from the link in the BadWolfYe thread here

4)ADB reboot bootloader' from the command line and enter 'fastboot flash recovery twrp.img'

5)Press and hold volume up and power until you are in TWRP and then back up your OEM partition. (if you can't get into TWRP then you may need to repeat step 4 and also do 'fastboot flash recovery2 twrp.img).

6)Use the File manager in TWRP to replace the OEM files with files from the zip file download link in this thread above.

7)Restore OEM partition and then use the Shutdown option in TWRP.

8)Download the ROM from above This BadWolfYe link and unzip to find 3 files.

9)Place files in a folder called HWOTA on a microSD card and place card into phone

10) Download this file from this guide and extract to your computers hard drive.

11) run update.bat from that extracted contents as an administrator and follow the on screen instructions. The on screen instructions basically take you through from step four on the stechguide.com method 1 through to the end of the guide. I think I remember you get some options and I just use option 1 twice, from SD card and not rebrand.

If you can follow the guides they should work fine and you'll end up with a completely stock dual SIM phone with a locked bootloader.

From that point on I unlock the bootloader on mine again, install TWRP again and use it to flash Magisk 12 for root. Using root and Titanium Backup I restore my old device ID and a bunch of apps and settings and things are fine. However on the next reboot the launcher refuses to run and I'm left with an unusable phone (I don't know how to launch apps without the launcher) and I get error messages about running short of space as something has filled the internal memory with what appears to be junk files. I then start from step 8 in my guide and get a phone with a locked bootloader and no root but the device ID I want and all my apps and data.

If someone could offer me any help with regards to this last part I'd be grateful. I don't understand what causes the launcher issue.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] resch13:
Fixed...

Device ID, I think same - unfortunately my PC was stupid (nooo, not me) and I make the note in it so I lost it

2 SIM works - however only EE ones so the phone is locked. (Testing the online unlock code sellers :D)

Bootloader locked

Met "ndr90m test keys" as dave852, but hes linked page and 1. method helped. Oh, and could not install L29 ROM with volume + - and power, only with the linked method. I think that method could do everything after you opened bootloader, but will not test it. I am happy with my L29 :D

But the important, there is a way to make L29 from L09 :D
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] dave852:
I would guess it would be possible using the files from the OEM backup you made (if you kept them) and a downloaded L09 ROM (available in a few places) but I'm not 100% sure and I'm not going to try it.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] resch13:
No, I have not any backup. I forgot to made any so I am lucky that I did not need it :D
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] toxxyk:
I somehow managed to convert my single sim to dual-sim but unfortunately i cannot modify nor set any ringtone to the 2nd sim. Any ideas of how i can fix it ?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] JohnRogers:
LOL. I gave this several attempts, alas, without success. I kept ending up with the test keys / strange device ID (ION something).

So I decided to skip my rebranding attempt and go back to L09. After "rebranding" it to L09 again and after flashing B130 for L09 I ended up with dual SIM support anyway. Eveything seems to be checking out as far as I can tell. Not sure if OTA will work though, time will tell I guess. Safety net etc. also checks out.

The options for dual SIM are showing and I've tested it. Everything just works.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Shu_S:
Can anyone confirm that after enabling the second SIM slot that their phone now has 2 x IMEI numbers?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Misia:
I just recently purchased p10 plus . for 3days the Fone was working fine both sims 3/virgin then suddenly emergency calls only on 2nd sim. I tried to deactivate activate ect ect . until I lost both sims. Soft hard reset sim 1/working sim2 emergency calls only. If I swap the sims around in the tray same issue . then with only one sim either 3/virgin full teceotuin if I make or receive a call after the call I have no reception I wil l need to swap the sim from tray1 to tray 2 . and the funny thing is both sims will receive and send texts all day long with no issues

Any ideas

Thanks in advance

Has anybody done this and checked warranty status in Huawei Hi Care app?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Marco_Snow:
I can confirm this works 100%. Dualsim working. Serial, imei all still the same. Recovery back to original too
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] haxus:
Hello and THX for the HowTo whch worked well!!!

My Phone is shoing that there is an update (VKY-L29C432B133-FULL 2.76GB) which i try to install via the regular updater, however the updates always failes. I already installed the default recovery image.

Any Idears?

ERROR: Package Checksum

... Never mind - it was a network error on my e1000 :fingers-crossed:
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Marco_Snow:
Mine updated to 133 OTA without any issues.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] joerome:
Do you get a secondary imei for sim 2 with this mod?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Marco_Snow:
I didn't though. But both Sims work
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] adieSA:
saviour!

Was up until 2am trying to resolve the ndromtest issue but finally got it sorted. My P10 plus is now dual sim and everything is working 100%. THANKS!!
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] fabioff:
Does this also work with the regular P10?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] pboden83:
hey

Ota is still Possible after you flashed the dual sim rom ?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Marco_Snow:
Yes still getting OTA. Think I got 2 since the convertion
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] pboden83:
ty :)

Is an external sd card needed or can i use the internal space to do that stuff ?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Marco_Snow:
Actually don't know if internal will work. I know I could see the internal storage while doing it but I used an external card. Suggest getting an external and not even attempt trying internal. Just to be safe.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] teksin:
I can't reverse the rebrand :'(

Every time i flash the stock rom (B160) for the Single sim p10 plus, i have the dual sim menu in the rom. I did a restore of my oem info too. Doesn't work. And my sim card is not really reconize. No pin code, someone can help me? Thanks !

i was trying to rebrand my p10+ and i stuch at huawei erecovery... http://imgur.com/a/y8LHn

[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] marvyzoro:
Hi, I am in the same boat after restoring VKY-L29C432DualSIM. It goes to Huawei erecovery. How did you fix it? Any help would be greatly appreciated. Thank you!

---------- Post added at 05:59 PM ---------- Previous post was at 05:16 PM ----------

I was able to get into bootloader, so I ran the update script. Now I am getting this error below. Any advice is greatly appreciated.

Replace oeminfo to selected one, please wait...

[100%] /tmp/oeminfo.bin

error: unknown host service
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] smfilip:
Hi, I am considering converting to dual-sim, but I have one concern... Is it me or there are fewer firmware updates available for dual-sim version than for single-sim (I was looking at firmware finder- latest for dual sim is B123 and signle sim B160)?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Bloodlvst:
It went make a difference. In fact, if you use [MENTION=477335]Blackball[/MENTION] 'a ROM after a rebrand you will anyways have a great build and dual SIM.

I can confirm dual SIM worked fine on my L09 rebranded to L29.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] smfilip:
Tnx for reply, but I don't use 3rd party ROMs, because there is no OTA,and I don't have very much time to follow and manually install updates
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] PyroSn4ke:
Unknown error

Hey,

I did it exactly the way dave852 described it, but somehow I'm stuck in method 1 when I need to start TWRP and plug in the USB cable because when I press enter then nothing happens. So I tried method 2 and tried to flash the zip files manually with TWRP but I'm always getting an error like this:

installing zip file '/external sd/dload/update.zip'

Checking for MD5 file...

Skipping MD5 check: no MD5 file found

check_write_data_to_partition,write data error

update_huawei_pkg_from_ota_zip: update package from zip failed

E:unknown command [errno]

Updater process ended with ERROR: 9

Error installing zip file '/external_sd/dload/update.zip'

Updating partition details...

...done

Could someone please please help me to fix this problem? It's driving me crazy because now I'm sitting on this weird version with test keys and so on which has Dual-SIM unlocked but it's on EMUI 3.1 and I'm struggeling to get back to the Stock ROM now... :crying: :confused:

### UPDATE 05.09.2017 ###

Problem solved! Device wasn't available via adb, had to execute the commands in the script manually.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] klsystem1:
is it also possible with this tutorial to flash a p10 lite from single sim to dual sim ?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] abdulhamid1978:
Thanks, I followed the above steps and managed to get my Carphone Warehouse single-sim L09 to dual-sim L29. Sim 1 is up to 4G and Sim 2 is up to 3G.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] dave852:
That's exactly what I have from my Carphone Warehouse P10 plus. I was a little disappointed it wasn't 4G for both slots but much better than the 4G and 2G combo you usually get in the UK.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] abdulhamid1978:
Is your dual-sim unlocked to all network? I haven't had a chance to test as I only have an EE network sim (BT).

edit: Managed to get hold of a Vodafone nano-sim and it worked
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] dave852:
I've tried Vodafone and 3, both work.

Just FYI both SIM AND microSD card slots work at the same time if you're willing to pull apart SIM 2. I've done it.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] abdulhamid1978:
Has anyone checked if Smart Remote (IR blaster) is working?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] dave852:
Works for me, why wouldn't it?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] abdulhamid1978:
It wasn't working for me. Tried a factory reset and still nothing. Called Carphone Warehouse who said to return it for a replacement. Thought I would give the HWOTA another go and set up IR remote from B123. Seems to now be working even after updating to B162.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] nehvada:
i have today received the information that all p10 will get the dual sim support with future updates from huawei. i have a p10 VTR-L09, which is singel sim as per data sheet, but works with dual sim after firmware update.

it is NOT rooted, unlockes or in any other way modified.

can anyone confirm this information?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] klsystem1:
Only p10 or p10lite too?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] mpokeras:
Any idea what practically means only one IMEI in re branded L29?

My other dual sim mobile has two imei and i could have sms, and calls on same time, is this the case with the converted L29 with single IMEI?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] mutahharbashir:
thank you man, i was looking for this

having hard time to convert AL00 to L29

will try it and let you know
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] mutahharbashir:
Didn't worked
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] adamelphick:
Where did you hear this?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] abdulhamid1978:
I have 2 SIMS installed on my converted P10 plus. When trying the SIM toolkit it doesn't seem to work. The message 'SIM Toolkit is not available on this SIM card' comes up. Has anyone else been experiencing this?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] adamelphick:
OK I decided to bite the bullet and dual sim my P10 Plus - but I must be a total dingbat as the various processes make no sense to me at all!

I have come from Samsung and LG and I was fine with flashing them - but I seem to be totally lost on this one! I think because I have read various methods and some work for some etc.

Can someone do a point by point How To possibly? I almost went for FunkyHuawei as I just couldn't fathom it - then realised that although you only need 2 credits for them, they make you buy 5 as a minimum! Sigh

Sorry if I sound stupid - but it's just not clicking in my brain for some reason!

Thanks in advance.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] adamelphick:
After reading up on their forums, and the help that was available if something went wrong I decided to go with FunkyHuawei.... about an hour later my phone was Dual SIM.

With windows 10 64 Bit there are some issues with ADB/Fastboot drivers that I sorted by manually getting Windows to check for drivers and once they reinstall from the existing available that was fine. Also Fastboot can only connect to the phone once it has been manually put in to fastboot mode, and also you have to put it in to recovery manually as well. Other than that the only thing was the router DNS alteration they need tocpnnect to their update servers - my Virgin router doesn't allow that so I turned my PC into a wireless hotspot (sharing it's ethernet connection via wireless) and then connected the phone to that when asked by the Huawei updater - worked a treat.

After 4 Hours (and working on a lack of sleep) I managed to get this working! <3
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] mpokeras:
Any clue?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] mutahharbashir:
Your both sims work with same imei.

No difference in functionality

You can still use 2nd sim for calls, sms, data.

Installing 2nd imei is possible with some paid tools, but it's illegal In most parts of the world.

Has anyone had any success converting a Canadian P10 Plus on Rogers (current firmware VKY-L09C654B198) to a dual SIM? Which firmware would be required for the L29 conversion? Thanks.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] obic:
No anyone?

so somehow i was make faktory reset using original EMUI screen but still same, just come to orgiginal recovery mod by wi-fii. i think have some problem with bootloader file. so please tell me what you think or how can solve it.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Planet X:
Turn Off the phone. Keep Volume down pressed and connect to PC with USB. The phone should now boot to fastboot screen automatically. Then you can use fastboot from PC again.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] mutahharbashir:
It should be volume down that needs to be pressed.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] obic:
thanks you all, but what should I do after that, I am scared now to do something wrong.

---------- Post added at 06:51 PM ---------- Previous post was at 05:56 PM ----------

I did flash some img files but no have any change. still same, not start on TWRP*Recovery mode. :((
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Planet X:
If you are able to reach fastboot mode than your phone can be recovered. Make sure that your bootloader is unlocked, else you can't flash a recovery. fastboot oem unlock unlockcode. After that you can flash a recovery like TWRP or the modified erecovery. For more information you should read the following thread: https://xdaforums.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108. It's your choice to make it stock or flash a custom rom like fRomFuture rom.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] obic:
i was unlock it ones using code, need do it again? i will try to do, thanks
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] obic:
so' bad news, I think bricked. cannot power off it. stay only error mode. no any command wit volume- + power.

say attention! please update system again.

error!

funk no: 11 (recovery image)

error no: 2 (load failed)

so what now? have I any change to solve it?
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] mutahharbashir:
Let the battery drain completely.

Then hold volume down and connect with pc.

If it enters fastboot mode, possible to recover.

I have fixed one similar phone
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] obic:
hi dear,

so what can be problem, why I cannot install any update zip file on recovery mode, all time get error.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Planet X:
I cannot tell you what the problem is. It seems that your bootloader is locked again. If you want to do anything you will have to reach fastboot mode. Then follow the steps I have written earlier.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] obic:
hi dear, i dont think so, bootloader is unlocked, i can use fastboot mode no problem with it. i was upload 3 zip file in internal sd like update.zip , vky-l29xxxx.zip etc. then was start in boot menu exept 1 zip all others cannot install and get faild message. i read more and more but i think maybe i did something wrong or dont understand :(( i was flash meny times recovery, recovery2, boot but nothing changed.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Planet X:
If you can boot into fastboot, why don't you use just the update mode from the rebrand guide in the MATE 9 forum. The link I did post earlier. Just put the (renamed !!!) zip files into HWOTA map on a micro-sd card and start the batch file and choose update from sd-card. He made it really easy for us.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] rodalvas:
Hi guys, I attempted to flash my new P10+ as suggested here (did the backup / restore) but I missed the modified erecovery.img step, so it's now stuck in "Huawei eRecovery" and tries to "get package info from server", which fails miserably ("Getting package info failed").

And it doesn't go beyond this point.

Is there anything I can do about it now? (no fastboot or adb access :( )
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] Misia:
yes i did the same ,, u need to read post 10 take ur sd card out and change the omni files and youse your twrp to install again ..

i was in the same situation and sort of sorted mine "JUST MAKE SURE YOU DO NOT CLICK YES FOR REBRAN" as now i have a p10plus that thinks its a ONYXD189 with a locked bootloader . i have to redo the entire process stuggling with the huwaie bootloader unlock cde at the moment

and all becouse i accidently clicked rebrand #

Hi guys I managed to follow the guide and flashed my p10 plus to VKY L29 , it is not registering both Sims, also it is now not registering 3mobile sum at all,. Vectone and virgin are both fine when both Sims are in it shows no service in 2nd SIM , I I just use 3sim it will not register. Anyone shed any light on this please

Many thanks

hi

did you get any joy from the online unlock code sellers, i have a simular issue l09 to l29 picking up vectone and virgin sim (only single sim), wont register 3mobile sim
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] adamelphick:
My 3 SIM worked fine so it's not a 3 issue I think. Used it in Asia and 3 still worked alongside local SIMs in Laos and Thailand.
[Huawei P10 Plus ROMs, Kernels, Recoveries, & Other] darachau604:
Your VKY-AL00 is already dual sim. You'll need to rebrand to achieve the VKY-L29.

That's what I did.

Greetings folks,

i have VKY-L09

i came to step where you need to start update via POWER OFF, Vol+ and Vol-.

Update started but its kinda stuck at 5% now for around 15 minutes. Is it supposed to take that long or i should try to power it off and start update again?
