How to enter flash mode

  • Download mode: Volume Down + Power + Home
  • Recovery mode: Volume Up + Power + Home

Installation

pmbootstrap flasher flash_rootfs and pmbootstrap flasher flash_kernel

Display

  • in landscape
  • If you use lightdm (Xfce, Mate), You need to set logind-check-graphical=false in /etc/lightdm/lightdm.conf
  • blanks after inactivity, likely some power-saving feature
    • echo 0 > /sys/class/graphics/fb0/blank turns it back on
  • fuzzes out after wake from suspend
    • X fails with
FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument
FBDEV(0): mode initialization failed
Fatal server error: AddScreen/ScreenInit failed for driver 0

Audio

  • Needs soc-sprd-audio-sc8830 package
  • Headphones and back speaker works
  • Headset and Handset only gives microphone and it's low volume, but /usr/share/alsa/ucm2/conf.d/sprdphone/HiFi can be patched to fix both. Like this

PulseAudio

Need to add add these lines at /etc/asound.conf: 

defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 1

Also need to edit this line in /etc/pulse/default.pa: 

load-module module-udev-detect

To: 

load-module module-udev-detect tsched=0

WiFi

You can copy /system/etc/wifi from stock rom to the device, then wifi works

One weird issue is it seems to not connect at all, but you have to use nmtui for first connection. then it just works.

Input

HID buttons

  • event0: sci-keypad
    • home, power, volume keys

Touchscreen

  • event1: MELFAS_MMS449_Touchscreen
    • in portrait
    • includes "Recents" and back buttons
    • stops working on suspend, cat /sys/class/input/event1/device/device/device_enable reenables it
    • try a non-forceful reboot if it doesn't appear

Headset

  • event2: headset-keyboard
    • works

Accelerometer

  • event3: accelerometer_sensor
    • no output, doesn't seem to work
