Hello guys,I have one T100 with no service,I checked board,change ant switch,processor,PA,yet no joy.Any one with the clue.

The A800 doesn't have network,I check the pcb,resolder most signal component.The network came and then disappear after about five minute.I then change the PA.Yet no joy,anyone with the clue.

Cheers.

for A800 you have to upload new eprom file with ust5.6 , which then after you'd have to flash repair flashes on .fb1 and .fb2 with the same software then full flash the phone with toolbox or A800 flasher. All files and software mentioned can be found on this forum.

for the T100, i've come to realise that even if one small compnenet (diode,resitor etc) is missing from the network circutry area you get limited service or no service! check and replace duely if found then heat pcb at antenna switch, PA , and upload eprom with ust5.6 again. still no network full fash must work else broken lines on PCB wich unfortunatly M8 you'd have to figure out yourself!
