10. Check PURX 2,7V at J101 after pressing powerswitch - if not ok, change CCONT N102

11. Check 13MHz Clk frequency (RFC) at C613, approximately 800mVpp if not ok, check values around G602 / V600 change HAGAR N500 if necessary try to flash the phone - if not ok - continue with section „FLASH update not possible" Note: it is necessary to run energy management calibration after changing CCONT N102! NOTE: for Energy managemant calibration see also general tuning information page!

FLASH update not possible

Check if fault code from prommer is one of the following : MCU boot failure, serial clock/data line failure: yes goto 3 Algorithm code fail, alias ID missing: goto 2. External RAM failure:

1. Check values at MAD D301, if ok - SRAM D310 faulty / change FLASH D311 if necessary

4. VB line faulty - in most cases is CCONT N102 the reason. If fault persists after changing CCONT, it is also possible, that capacitor(s) in VB line is/are faulty (C105, C122, C123, … ) check all these components lifting one after the other, with repeated current testing, probably one of the µBGA CSP´s and / or ultimately the PCB should be the reason

5. Check current in sleep mode: 2.35-4 mA. If ok, goto 6 Check resistance of all voltage output lines of CCONT N102 to GND Change component(s) in corresponding line(s) if resistance is not ok

6.

NOTE: for Energy managemant calibration see also general tuning information page! Check charging circuit, run energy management calibration. If calibration fails - continue with section „Not charging" Align RX / TX values. If calibration fails - continue with section “RX / TX faults” Note: Standby time also depends on network side and users handling, like lights on/off, VIBRA- / WAP activities, games etc..

Contact Service MCU ROM Checksum failed:

Try to flash the phone. If not ok - change FLASH D311. If failure still persists after rework of FLASH, MAD D301 or PCB should be the reason

CCONT Interface failed:

N102 faulty and/or probably broken solderings under CCONT. If not ok after rework of CCONT, probably MAD D301 or PCB faulty Note: it is necessary to run energy management calibration after changing CCONT N102! NOTE: for Energy managemant calibration see also general tuning information page!

DSP alive test failed

In most of all DSP alive selftest failures - MAD D301 faulty, which is not changeable!

EEPROM tune checksum / EEPROM security checksum failed

Use Wintesla to check if phonedata like IMEI-, product- or PSN- data are corruped / missing If phone data is ok try to reset the phone. If phone data is not ok, or fault remains after rewriting phone data - change FLASH D311

RTC Battery failed

First try to charge RTC battery, by connecting battery to the phone for app. 10 minutes. If fault remains after disconnecting/connecting battery - check contact springs of battery and Pads on PCB (if dirty etc.) - change LCD unit and/or CCONT N102, CHAPS N100 if necessary
