What works
- Compiling the kernel and booting (!314)
- Wifi with the proprietary firmware (!309)
- Display
- TouchScreen
- Flashing via android recovery zip
- Wayland/Weston/Xwayland
Notes
- Most variants are single SIM, SM-G930FD is hybrid dual SIM.
- The device and kernel packages are basically just a copy of the Galaxy S7 Edge's packages. The only difference is that the two devices use different panels.
- using command: apk upgrade can cause loading forever...
Mainline notes
For uniLoader:
- To enable the framebuffer we need to write
0x1290
to address0x13960070
. To get this value search for thedecon_f
base address and add 0x70 (HW_SW_TRIG_CONTROL
) to it, then use devmem2 together with the value you calculated on a downstream kernel withCONFIG_DEVMEM
enabled. - The MUIC UART is located under address 0x14c50000. To get minimal output follow this guide (add 0x20 to the UART address for the TX offset).
