because of the missing possibility to rewrite phonedata after changing UEM D200 you should not change this part
-
D400
- if it was necessary to change UPP D400 you have to make SW-update after reworking this part. Otherwise the phone will
not switch on!
D450
- change Flash D450 in case that prommer box messages "wrong manufacor/ devive ID". Note that after changing D450 you
have to flash the phone, rewrite IMEI, Simlock data and Product code. Furthermore you have to run all RX/TX-tunings and
energy management calibration!
