V3r Invalid Battery
 

I have i pcs who show on display Invalid Battery ..... Please help me with any idea.
The metal shield was removed with hot air, maybe to make test point for unlock.
The battery is good because I check it with another phone.

Thanks in advance

I changed few battery and still have the same problem :( I found on forum something like that :

"i solved this problem on my v3, replace CR92
if the problem persist then need to replace U900"

What u think about this?

I try this but nothing happened .... any idea ?

I also found something like that:

"if no is problem batery, change filter vr1201, it is very near lcd conector in pcb. works 100%"

that it's on V3 but what about V3R ?! any ideea how to solve the invalid battery on V3R ?

you should not remove shield through hot air. i just cut a hole above the testpoints using slide cutter. that's the safest way.
