| As mohammed said, first try to unlock it. Then try to full flash it and recalculate faid with KNOK.
Then read the full flash from your phone with KNOK. Compare this file with file you used for flashing. If they are not identical - change combo flash again.
If above is OK, then check contacts, check/replace V104, R124, R125, R128, C128, C127.
Check the Vsim (3V or 5V) at C128.
Check the Vsrm at C131 RF and V5V at C108.
Check the regulator N600, V116, C132 and C131.
If everything above is OK, than change the CCONT N100. |
