Introduction:

This is the Unofficial Lineage OS 19.1 thread for the Huawei P Smart 2018 (FIG-LX1). This version of Lineage OS is a modified version of the original, containing different patches in order to make the device functional. I have made a couple of tweaks in order to boot on this device, as this rom is ported entirely from another build made for P20 lite (not made by me, credits at the end of the post).

ROM: Here

TWRP - Recovery: Here

GPS Patch: Here

(Only for devices running EMUI 9.1.0.405 or higher) DRM Patch: Here

GAPPS: Here

Other mentions and requirements:

You'll need a microSD card (at least 8GB).

The bootloader must be unlocked. You'll need a tool called DCUnlocker or PotatoNV (The first one is paid - around $5, the second one is free but requires you to physically open your phone). Also, you need to make sure that you are running on EMUI 8.0.0 build before JUNE 2018. Otherwise, you'll need to downgrade to an early version. I have downgraded to 8.0.0.128. I think it works with 129 too. Tutorial Here and additional info Here.

After getting the bootloader code, you'll have to put it in a safe place and upgrade again to any eEMUI 9.0.0.xxx. THIS ROM WILL

NOT

WORK WITH EMUI 8.0.0.xxx!!!

Also, the rom is not very stable for daily use. So, I do

NOT

recommend to use this ROM on your primary device! It's stable enough to be functional. (See bellow)...

INSTALLATION:

1. Download all the files (look for download section)

2. Extract the img file from the ROM zip

3. Flash system image : fastboot flash system <drag system.img here>

4. Flash TWRP image: fastboot flash recovery_ramdisk <drag twrp img here>

5. Boot into twrp: power and vol+ simultaneously while NOT connected to pc

6. Resize system: Wipe > Advanced Wipe > Check System option > Repair or Change File System > Resize File System > Swipe

7. Wipe cache, dalvik/art cache, internal storage, data

8. Copy GPS Patch, DRM Patch (see notes if you need it or not), GAPPS onto the microSD card

9. Reboot and ENJOY

Optionally, you can install Magisk via recovery by flashing the apk. Tested with the last version of Magisk, not working, cause bootloop. Further testing is required

Bugs and other problems:

Charging while the phone is powered off (atm there is no fix available)

Bluetooth pairing with code (FIX: search for Bluetooth Force Pin app)

After the first boot, there is a system crash (everything crashes) and the system is unusable. (FIX: Restart the phone)

Weak signal with some carriers (atm there is no fix available)

Other UI settings and device specific functions

Secondary camera - testing EMUI camera port for Custom ROMs (Possible FIX, not tested - GCAM)

Possibly other things
