How to enter flash mode
Hold Power + Home + Volume Down buttons to enter flash mode. Hold Power + Home + Volume Up buttons to enter recovery mode.
Installation
Currently pmbootstrap flasher flash_rootfs fails at 17%, but pmbootstrap flasher flash_kernel works, so there are two ways:
- install on sdcard (untested)
- install via android recovery zip
Wifi
To make wifi work, we need some binary blobs (download and wcnd, both located at /system/bin/ in stock rom), so we can:
- use libhybris
- see how Samsung Z1 handles it in Tizen (uses some Spreadtrum chip)
- recompile them from leaked sources
