i guys, After reading this interesting thread, and quired a few new software(raw2bin). I have done a complete readout of my W800i_CXC1250093_HongKong_R1AA008 with camera focus, shutter, timer disabled in normal and silent mode. Please rename data_44000000.bin to raw.bin and run raw2main.exe and you should get a 32MB file which you can flash with Sonic. Ill post R1N up tomorrow with the camera sound disabled. I can try to do the same with the k750 firmware if you guys like.
