Installation
pmbootstrap init pmbootstrap install (enter fastboot, see below) pmbootstrap flasher flash_system pmbootstrap flasher boot
To flash the kernel, you can choose pmbootstrap flasher flash kernel
(but charging and power off doesn't work as expected anymore, see below).
Entering "Fastboot mode"
Hold Volume Down
+ Power
, let go of Power
once the device display does something (e.g. turns from battery icon to black screen).
Charging and power off (after flashing the postmarketOS kernel)
You don't have to flash the kernel! pmbootstrap flasher boot is also working! |
You can flash the postmarketOS kernel, but instead of charging the battery, it will boot straight into postmarketOS (or the on screen keyboard to type in the password). Right now, the best way to charge it from that situation is to boot the recovery TWRP.
You can properly turn the device off by unplugging the usb cable, then booting into fastboot, then choosing power off.
What works
- Touchscreen
- Weston (has the red screen bug, but we have a workaround for that now 👍 )
What does not work
- XWayland
- The rest (Wifi, bluetooth, making calls, ...)
- fbsplash only displays splash images very shortly, then goes to black screen
Wifi
Looks like, we need to package the wcnss.* files for wifi. A version from 2015 can be found here. It's a Qualcomm chip.
Alternative kernels
It *should* be possible to run The Mainline Kernel on the lg-mako, maybe we need to write a display driver, but there's a tutorial for it. I (ollieparanoid) didn't do enough research on this yet - if you're interested in doing this, please talk to opendata26 from postmarketOS and robclark from the freedreno project. With their help it should be quite feasible.
Non-mainline:
- Freedreno backport to 3.4.0 (couldn't make it work out of the box and I suggest trying to get mainline working instead of spending time on this one)
- Freedreno backport to 3.0.8 (#38)
