well, I also think that its a hardware problem now. cause I tried everything, flashing back to old stock froyo, upgrading to stock gingerbread, cm7, baseband patch, but none works. I think that it needs to see LG care now. is anything else u want to advice me? any else trick or somethin?Hey mate, well no gsm is normally caused by the wrong baseband, so flashing back to the old one should fix the problem, try to re-flash the stock froyo given in the link on first post and see if that works, and if still no coverage then its a hardware problem and Lg should replace it for you, just dont forget to flash back to stock again if you rooted it, then they should fix it within the warranty.
