Platijet · 11-07-2004, 19:09

problem:
phone is dead(not even charging etc)
phone can flash but can't extract contect files and can't power on.

this happen in many dct4 model's and i deside to spend time to find solution
i have allready change:
UEM,UPP,flash,ram,helga,28Mhz vctxo,32Khz vctxo and some capacitors etc

from my experience on microcontrolers and microprocesors i thing this can be happen because of resset on UEM and UPP.on service manuals i can't see where is the reset circuit.

any idea???
