Huawei P smart 2019 (POT-LX3)

Requirements for flashing GSI:

• Downgrade to EMUI 9.1.x (see this guide).
• Unlock bootloader (it is a paid service, click here for more information).
• After successful bootloader unlock, downgrade to EMUI 9.0 following the guide provided before. THIS IS AN OBLIGATORY STEP, OTHERWISE WHEN YOU TRY TO FLASH GSI IT WILL TELL YOU THERE'S NOT ENOUGH SPACE AND YOUR PHONE WILL BE BRICKED!

Procedure:

• Get an arm64-A/B GSI (it should be 2.6gb or less, otherwise it won't flash)
• Get platform-tools from this link.
• Get vbmeta.img from this link.
• Reboot to fastboot mode adb reboot bootloader.
• Flash the vbmeta.img you downloaded executing the following command: fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
• Flash the GSI you downloaded executing the following command (don't forget to decompress it): fastboot flash system gsi.img
• Reboot and enjoy 👍
• As an alternative you can flash via TWRP as "System Image".
