Issues
- WIFI firmware sometimes does not load on boot. WIFI connection is very slow - probably to the wcn36xx driver still being a work in progress. You need to start WiFi#Start_WIFI_manually as the firmware loads late in the boot process.
sudo wpa_supplicant -u -Dnl80211 -B -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 sudo nmcli device wifi connect "ssd" password "pass" ifname wlan0
No space left on device
orUnknown chunk type
can show when trying to flash large images (for me, it failed for images >~700MB). Try flashing to the USERDATA partition as described here: https://wiki.postmarketos.org/wiki/Google_Nexus_7_2012_(asus-grouper)#Flashing_rootfs_larger_than_650_MB.
Other information
- Flash the system to a userdata partition to have 10GB free space. If you don't see 10GB install TWRP recovery and format system/all partitions and start again:
./pmbootstrap.py flasher flash_rootfs --partition userdata ./pmbootstrap.py flasher flash_kernel
- When I tried flashing rootfs, it would fail almost immediately after erasing. I installed TWRP, and tried a few things to "wipe" it, which worked, and then permitted the good flash (with hildon UI) below. (Note that, although the instructions for TWRP 3.2.2-0 for asus-flo suggest that you might need to do "fastboot reboot" and then hold down the buttons, that only resulted in what appeared to be boot loops of TWRP -- what worked instead was to use the buttons to power off, and then use the buttons to boot recovery.)
(native) flash rootfs image target didn't report max-download-size erasing 'userdata'... OKAY [ 0.977s] sending 'userdata' (395264 KB)... OKAY [395.414s] writing 'userdata'... OKAY [ 19.449s] finished. total time: 415.840s
- When I tried flashing with the Hildon UI (on 2018-07-27), it booted to the blue Hildon wallpaper, but the wallpaper only filled a square subset of the display.
- For unknown reasons, I'm seeing rootfs flash times that seem slow. For example, a flash of plasma-mobile ui (808 MB) took 850.323s, with 808.169s of that in sending phase. This is approx. 10 times the duration for flashing sony-amami from the same laptop.
- I would recommend installing and using MATE as it is very complete
