Installation
pmbootstrap init pmbootstrap install (enter fastboot, see below) pmbootstrap flasher flash_rootfs 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)
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.
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.
Mainline
power_graphic's mainlining progress is here. Read on for generic instructions of what would need to be done.
Currently we only have a downstream vendor kernel packaged, not the mainline kernel. The lg-mako
has the same SoC as the asus-flo
, and on the latter it is possible to run Android on a kernel close to mainline.
This means, that most peripherals of the mako
should work with mainline as well, once they are enabled in the DTS file. In fact, @vetzki reported in #1079 that the mako
boots when using exactly the same DTS as the one from flo
(this is not recommended, as misconfiguring your device like that may damage it). SSH appears to be working for a short time before getting kicked out, the display does not work.
A good way forward would be using a minimal version of the flo
DTS, where everything but USB is deleted, and fixing USB / trying to get the display working with the DSI Panel Porting Guide. The downstream DTSI files that need to be ported to the upstream kernel are probably located here, and I guess the exact panel name appears when running dmesg
after a successful boot (I did not verify this). Please expand this when you're working on it, and report your progress in #postmarketOS. Check out the Mainline Guide.
