Signal issues

[perrillo1984]

Hey guys I have an old A780, I already flashed it with a German version of firmware, now I live in Central America and after flash my cell the signal becomes very poor, I mean I really need to stay just beside a signal tower to get a good signal, do I have to change something on the firmware or do I really need to change my old phone.

Thanks,

i have not seen any difference in signal quality on different firmwares.
have you checked your network setup?
maybe you have only enabled 2 bands.

hehe sorry for my ignorance on this but where in the phone I can can find that network setup? I have been trying everywhere I guess may be I missing something, thanks for your reply

calling keypad (upper right corner) -> "setup" in the menu (lower left corner) -> "network setup" -> "search setup" in menu

ok I did that, now do I have to have at least a little bit of signal, because with the SIM card inserted it show me other options and I don't have signal at all here at my work with that cell phone.

can you test the SIM in another mobile at the same place.
i have had nearly the same reception with an old V3 and my A780 at bad places.

Actually I have a C139 and it has not too bad signal here.

it doesnt look like a software problem to me, but it is never a failure to make tests with different firmwares (this is easier than hardware disassemply)

dropping or weak or distorted audio.

Check to make sure that the antenna pin is
properly connected to the transceiver board
assembly. If connected properly, substitute a
known good antenna. If the fault is still present,
proceed to b.
