If you want to install pmOS to an SD card instead of internal storage, you need to add --sdcard <device path> at the end of the install command.I.e. (using lk2nd): pmbootstrap install --add msm8953-lkn2d --sdcard /dev/<your_sdcard> |

Modem
Firmware loads and modem boots. It detects SIM card and can be unlocked and configured with qmicli.
Because audio needs more work i couldn't test audio quality on calls but with q6voiced it should work.
Mobile data
Mobile data works with ipa-lite on 6.7.0/main branch.
To configure the mobile network settings, use NetworkManger (mobile network menu on phosh settings) so it sets up the network interface and IP routing.
After that, two new network interfaces should appear. The rmnet one is the connection to the modem, and the other one is virtual and the one that is used to transmit mobile data.
GPS
Qualcomm_Snapdragon_450/625/626/632_(MSM8953)#GPS
Touchscreen
Both goodix and edt touchscreens are supported.
However, touchscreen selection is binded to the display panel, and sometimes the same panel comes with a different touchscreen. As a result, you might need to manually override it in lk2nd.
To do so, you will need to edit and compile lk2nd yourself. First, clone msm8916-mainline/lk2nd.
Edit touchscreen-compatible
Next, edit the following parts of the DTS file corresponding to your device.
sakura | lk2nd/device/dts/msm8953/msm8953-xiaomi-common.dts#L48-L59 |
daisy | lk2nd/device/dts/msm8953/msm8953-xiaomi-daisy.dts#L23-L34 |
Play with the displays' touchscreen-compatible
value. This value should be either of:
"goodix,gt917d"
"edt,edt-ft5406"
For example, if your touchscreen does not work, change every goodix to edt and vice-versa.
Build lk2nd
After that, you need to build the lk2nd image. Run the following command from the repository's root directory:
$ make TOOLCHAIN_PREFIX=arm-none-eabi- lk2nd-msm8953
See msm8916-mainline/lk2nd/README.md#building for more details on the building process.
The resulting image will be in the build-lk2nd-msm8953
folder as lk2nd.img
.
Flash lk2nd
To flash lk2nd.img
, run the following commands:
$ fastboot boot lk2nd.img
$ fastboot flash lk2nd lk2nd.img
Finally, you can run:
$ pmbootstrap flasher flash_rootfs
And reboot your device.
Goodix touch display calibration
Install device-xiaomi-daisy-fake-goodixPMOS if your replacement display with goodix touch controller is not calibrated well.
