Architecture
![]() |
Note: Even though MSM8916 is capable of aarch64, the firmware of some variants were never updated with aarch64 support. Therefore, this device can only boot mainline on aarch64 at the moment. |
Installation
lk2nd is a secondary bootloader that provides a standard fastboot interface, which can be used to boot postmarketOS without android boot

.

There are 2 panel variants, and lk2nd is required to enable the panel[1][2].
This device is based on the Snapdragon 410. See the SoC page for common tips, guides and troubleshooting steps |
Charging
rt5033-charger
driver is not available, so the charging is not controlled and there is no charging status reporting.
There was a forgotten patch[3] from 2015 on the kernel mailing list. Jakko picked up the work on top of that, and the review started in February 2023 [4].
USB OTG
Another rt5033-charger
driver issue. It's currently unable to power up a USB device in mainline; in some cases, it may be possible to use OTG with an USB hub that supports an external power supply.
Flash LED
Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver[5].
GPS
No idea how to test yet.
Proximity Sensor
No interrupts received from gp2ap002s00f
sensor.
Accelerometer
lis2hh12
accelerometer is not so stable for auto screen rotation, which suggests you to use fixed portrait or landscape mode.
Touchkey
Touchkey type is unknown, so there is nothing done for it.
TWRP
- Install
Heimdall
- Download TWRP
- Enable USB debugging in the system preferences
- Press Power + Vol down + Home to go into download mode
heimdall flash --RECOVERY twrp-file.img --no-reboot
