2100 no signal - GSM-Forum

hooi76 · 03-15-2004, 15:10

I tried to full flash (20-40) and do all the necessary thing in updating FIAD, SIMLOCK and IMEI. I even tried changin/reballing the FLASH IC, HAGAR COBBA PA and antenna switch. But the phone still no signal, The connection between the antenna to the borad is OK. CCONT is sealed, so i didn't do that part, i guess the CCONT is working.

But all the above done, still no signal.

Please assist..
