At first you should try an energy management calibration, either to define the defective area, or the phone works well after calibration you hope.
Try calibration, if charging process stops too early or doesn´t start and if message “NOT CHARGING” appears on Display.
If calibration failed – check possible failure message :-
Battery temperature failed : Check X120, X121, R122 / R123, R124, V120, change N102 if necessary.
Battery size failed : Check X121, X120, R120 / R121, change N102 if necessary.
Battery voltage failed : Check L123 / R105 / C104 / C105, change N102 if necessary
Charge current failed : Check R106, change N100 and / or N102.
Charge voltage failed : Check VCHARGE at voltage devider R102 / R103, if ok – change N102, if not ok - check X001, R101, F101, L101, change N100 if necessary.
V_IN line short-circuited to GND :-
Check resistance of V_IN line at F101 to GND (50 kOhm), if resistance is not ok - remove L101 and check again.
If resistance is ok now - C101 / C102 or N100 should be the reason, if resistance is still not ok – R101 faulty.
CCONT / N102 faulty :-
Change CCONT N102 if any A/D (calibration) value, is out of limit and DC voltage is ok.
If DC voltages are not ok, check corresponding voltage dividers and battery connectors X120 / X121, always realign RX/TX and
AD values after changing CCONT N102.
Check the service manual for more info on Energy Management Calibration.
OR if you cant do any of the above you could try and read full flash/eprom contents from another 6210 and the change the imei back.
Hope this helps.
