IMPORTANT INFORMATION
Changing of EEPROM D301
If it is necessary to change D301, take a look at chapter 2 on page 14 "Changing of D301" how to proceed.
Furthermore never change D301 if you have no permission to rewrite IMEI – otherwise all phone data will be lost!
To avoid further problems send the phone to a higher-level NOKIA Service Center.
Changing of COBBA N800
If it is necessary to change COBBA, you have to rewrite IMEI & SIMlock data and flash the phone!
Also RX/TX-values must be realigned.
Changing of CCONT N700
If it is necessary to change CCONT, you have to realign A/D values.
Changing components in RF-part
If it is necessary to change any main component in RF-part (IC´s, oscillators, filters...) you have to realign all RX/TX values.
In case of problems to tune RF-values of GSM1800 band, check in WinTesla Configure/Options if automatic rescan function
is activated for the phone. If selected, the band will change to GSM1800 but due to the rescan the phone changes back to
GSM900. To solve the problem deactivate the automatic rescan function if necessary.
