OK
To 1) - The flash 1 (D352) is faulty. This can be seen at the second flash ID (0000-0000) in the first case.
To 2)
- In the most cases D351 is faulty, but also the whole Flash (D351- D354) or D300 MADLINDA could be faulty.
To 3) - In this case all flash IDs and MADLINDA are OK.
If one of the IDs is 0000-0000, check Vcore = 1.8 VDC and VBB = 2.8 VDC at following components:
-
D351 Vcore at C360/C361
D352 Vcore at C362/C363
D353 Vcore at C366/C370
D354 ---
- If Vcore is not ok, check Vcore = 1.8 VDC Pin 4 and Vbatt = 4 VDC at Pin 3 of V105 (VBatt depends on settings of power
supply at the workbench).
or change faulty ones if necessary.
If VBB is not ok, check VBB = 2.8 VDC at C111. If not ok, check VB = 4VDC at Pin 6 of N102.
-
If VB is ok, check N102 and surrounding components for shorts or disconnections and resolder or change the faulty ones if
-
necessary.
- If all voltages are ok, change the faulty Flash and flash the phone.
-
If the fault persists, probably the MADLINDA (D300) is faulty. Up to HW 4.00, the D300 is not changeable because of
underfill. From HW-ID 4.23 with OSP, the MADLINDA is changeable. (See SB-027)
