I would like to share a little contribution. Perhaps could be useful to someone..
First of all, all credits goes to angelbbs
and his great work on http://solaris-club.net/forum/showthread.php?t=19729
forum and stanjkof
for his app radio mod.
I just used angelbbs lastest work with 51t firmware to fit my preferences and needs.
changed default launcher (Holo Launcher HD)
changed default app radio with excelent mod from stanjkof
changed fileexplorer and commander with miexplorer (just simple, friendly, and powerful app)
Removed some unnecesary apps.
Modified: gps.conf , build.prop, p901.cfg, sun4i-keyboard.kl and other files that i can't remember
This image can be flashed with usb method or more easy with an sdcard.
You can use PhoenixCard to format sd with the firmware.
Then just insert sd in to gps sd slot and wait.
