BIG clock when screen save on 8850 ,in coming call , 8850 has twinkle LED


HI mate,
Very happy, my 8850 has to glitter when some incoming call !

success to modify 8850 modify to 8855 !

3 different at HW , it is A21 from MCU to flash rom ,, you need to put a wire !

also one VBB inside Flash rom A10 !
then change flash rom F320 C3T !!

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 .

Willy

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

HI Mikimiao,
3310 /3330 has more then 2 different HW version,, you got lucky, it is already line up . if there is already has line, just change flash rom and RAM is enough !

yes, my 8850 is load 320 flash rom now, with SW is NSM-4
