[Huawei P10 Lite Guides, News, & Discussion] Aalesund:
You can REBRAND your WAS-LX1 (3GB RAM) or WAS-LX1A (4GB RAM) to C432 (European version) and CONVERT Single Sim to Dual Sim!

YOU NEED ANDROID 7 (EMUI 5)!

If you're using Android 8 (EMUI 8) you have to roll back to Android 7 via HwOTA8, then you can REBRAND/UNLOCK the phone and then you can upgrade to Android 8 via HwOTA7.

===================

Requirements:

At least 50% battery charge

Fully Unlocked Bootloader (Phone Unlocked and FRP Unlocked) (Go to Fastboot mode and you can see if it's fully unlocked or not)

TWRP ( You can use any TWRP for P10Lite with EMUI 5, here's a link if you don't have one: https://mega.nz/#!WFYWEJjJ!HZGsY4WKdbYGr6M8VEeztDCzQe6UN020ro6f_g6V8FY )

ROM Warsaw-L21_C432 (Download link: http://androidhost.ru/JT)

===================

LX1A (4GB RAM) owners: Еverything is the same as in the guide below, just use WAS-LX1A C432 Dual Sim OEMinfo and folder WAS-L21A_hw_eu (contains the file update_WAS-L21A_hw_eu.app)

How to:

1. Prepare your SD Card:

Download the archive: Warsaw-L21_C432B182_EU_SERVI CE_androidhost.ru.rar

In the root directory of your SD Card create a folder "dload"

Put the file UPDATE.APP and folder WAS-L21_hw_eu (contains the file update_WAS-L21_hw_eu.app) inside your dload folder

Must be: "SDCARD\dload\UPDATE.APP" and "SDCARD\dload\WAS-L21_hw_eu\update_WAS-L21_hw_eu.app"

Download the archive: DUAL-SIM-OEMINFO-C432.zip

PUT the folder "DUAL-SIM-OEMINFO-C432" into "SDCARD\TWRP\BACKUPS\YOUR_PHONE_SERIAL_NUMBER"

Must be: "SDCARD\TWRP\BACKUPS\YOUR_PHONE_SERIAL_NUMBER\DUAL-SIM-OEMINFO-C432"

Download the archive: Huawei P10 Lite-OemInfoC432DualSim.zip

Put the file Huawei P10 Lite-OemInfoC432DualSim.zip to your SD Card

2. Instalation:

Reboot into TWRP, create a backup of your original OEMinfo (if something goes wrong and you need your original oeminfo)

MOVE or COPY your original OEMinfo somewhere in a safe place

Now you have 2 choices (it doesn't matter which type you choose but you can use my recommended method):

(Recommended) Restore TWRP backup: Go to TWRP -> Restore and select a folder "DUAL-SIM-OEMINFO-C432" then restore the OEMinfo partition.

(Not Tested) Install ZIP via TWRP: Go to TWRP -> Install and select the file "Huawei P10 Lite-OemInfoC432DualSim.zip" then install OEMinfo.

Go to TWRP -> Reboot -> Turn OFF you phone

Once the phone is turned off hold all 3 buttons volume up, volume down, power until you see EMUI update menu

An automated system update process will begin

After successful upgrade your phone will have Dual Sim and STOCK WAS-LX1C432B182

===================

B182 is an old version and soon you will receive OTA update to B184 and then update to B194 and maybe newer versions later

IMEI 1: Your current IMEI

IMEI 2: 000000000000000

===================

Warning:

Then you will have LOCKED Bootloader (you can easily unlock it with the command: fastboot oem unlock YOUR_UNLOCK_CODE)

STOCK RECOVERY (if you want TWRP you have to flash it again)

===================

THIS WORKS ON MY WAS-LX1C432 (3GB ram / Single Sim) and now I have dual sim for free!

===================

It will works on WAS-LX1A but you need Dual SIM OEMinfo for LX1AC432 and you should use folder "WAS-L21A_hw_eu"
