Phone is totally dead
This means that phone doesn’t take current at all when the power switch
is pressed or when the watchdog disable pin (X001 pin 11) is grounded.
Used battery voltage must be higher than 3.0 V. Otherwise the hardware
of CCONT (N100) prevents totally to switch power on.
Phone is totally dead
YES
Check R118, X300
J232
VBAT is 3.6 V
NO Failure in VBAT line
Check X101, X102, L103
YES
Voltage at pin 29 of CCONT (N100)
is 3.6 V
NO
Faulty circuit N100
YES
N100 pin 55 (VBB) 2.8 V
N100 pin 25 (VXO) 2.8 V
when PWR switch is pressed
or watchdog disable pin is grounded
NO
CCONT (N100) pin 29 0V when
PWR switch is pressed or
watchdog disable pin is (X001)
grounded

Flash programming doesn’t work
The flash programming can be done via panel connector X001 or via sys-
tem connector X100.
In production, the first programming is done via panel connector X001.
After this, the panel connector is cut away, thus other flash programmings
must be done via system connector X100.
The main differences between these are:
a) FLASH programming voltage is produced different way.
b) Signal routings are different.
The fault finding diagrams for flash programming via panel connector are
shown in figures 32 and 33.
The fault finding diagrams for flash programming via system connoctor
are shown in figures 34 and 35.
In flash programming error cases the flash prommer can give some in-
formation about a fault.
