Cross Battery problem on BlackBerry 83xx
This software can also be hardware problem, check the damage with the following steps :
1. if the handheld is still detected in Desktop Manager may still be solved with software flashing or by reprogramming the operating system. cause is cod files on the system load is missing or corrupt.
2. but if not detected in the DM or other tools, this means the damage is certainly a hardware problem, the battery circuit conductor paths are not normal.
steps of checking the hardware :
1. check battery, can be a simple way to switch a normal handheld battery.
2. either clean the battery connector on pcb or on battery
3. check "crystal 91HCE2" (resolder / change)
4. inductor component checks all around power-ic
5. check the "regulator 907 ps 12" (resolder / change)
for step 3,4,5 please look at the scheme.
If the above steps have been conducted, but cross-battery problem persists, then it entered the advanced damage, which I will discuss in the next post.
