Well, i'm making this thread to help out guys like me lol

I found this one solution that has worked fine for me. Its a combination of a seem edit & a little tweaking to the phone's configuration.

On seem 0032_0001, go to offset 7F and check bit 1 ON.

That should solve the problem for some of you. If the problem continues, go to Network Setup and set the Detection Speed to Fast.

I didnt need to do the second one, and my signal reception improved a lot. In a friend's phone, i did the second, and the low signal issues really went down, improving even further the signal

If you have another proven idea, please send me an e-mail.

thanks to Archer for the original guide.
