Member: 1060 Status: Offline Thanks Meter: 10 | Magdi, 8850 to 8855 different at HW : 1: Flash ROM, (8855 same as 5210 ) 2: add two line (wire) : pin G3 at CPU address (AD21 ) to pin A3 at flash rom address ( AD21) you need to make a wire to link between CPU and flash rom ! flash ROM pin A10 , you need give Vbb ! 3: read 8855 full flash rom data and write to 8850 , then fix full lock, and IMEI .. that is say easy, and do hard work , please try it with careful .

Member: 1060 Status: Offline Thanks Meter: 10 | Mikimiao, 3350 used 320 flash, you need add in MCU pin G2 (AD21) to flash rom pin C5 (AD21) and also AD17 AD18 for RAM ! i think, it too much Willy Quote:
