it’s been awhile since my last custom rom for this gdf model and yesterday i’ve got a borrowed device. i think it’s nice to create xperia rom on this device, and here we go i share the results so it’s not my only friend who enjoy it but you all. Everything works as expected and well tested, but there is something i cannot test. my friend is kind of careless guy, the device he gave me is pretty in bad condition, scratched everywhere, the back casing is a little cracked on the corner and worst is the back camera is broken and no longer working. Looks like he dropped it sometimes and I cannot test the back camera is working or not in this custom rom. Despite that, i’m using the library camera module from the stock rom for safe and the ouput debug logcat throws no errors, so i can assume the back camera will work good.

Ok, here we go the features :

  • Boot into recovery mode by turning off your phone, hold down Volume + button then press power button, hold them both until you see Boot Mode menu, then release it. There will be 3 Boot Mode available on the list : Recovery, FastBoot and Normal Mode. Choose with Volume Up button to point to Recovery Mode and Select it with Volume Down button to enter Recovery Mode.
