"No GSM" error with 8525

[mcattack86]

I've tried just about everything and it keeps messing up. Here's what happened:

I got this phone in April from a local craigslist ad. The battery he gave me was old and only lasted half a day, so I ordered one off Ebay (big mistake!). I put it in and it has worked fine for the last 8 months. But one day last week, I went 2 days without charging the phone. Apparently the battery was in the phone the whole time while it drained to 0% (never had let it do that before). When I tried to turn the screen on, it wouldn't. I plugged it in, saw that it had 0 battery left, and left it there to charge.

Ever since then, whenever I've tried to make a call it would either:
-Freeze
-"Dialing..." forever
-Make the call but when I want to end, the sound goes off but the counter keeps going. I can't make anymore calls until I restart the phone
But if I restart the phone, 90% of the time it will show "No GSM" on startup and the phone will not connect to AT&T.
Also, in device information, the radio version does not show up.

Before anything started messing up, I was running Schap's v4.31 WM6 and I think radio version 1.3-something

I have tried:
-official WM5 ROM from AT&T (installed but No GSM error)
-official WM6 ROM from AT&T (always gets stuck at 11% and doesn't install)
-Schap's v4.31 installs fine every time but I get No GSM error

-Radio 1.47.00.10 installs and will work for 1 or 2 calls but then freezes and the No GSM error comes back when I restart
-Radio 1.48.00.00 installs and will work for 1 or 2 calls but then freezes and the No GSM error comes back when I restart
-Radio 1.54.07.00 is stuck at 0% and stays there for hours
-Radio 1.54.30.10 tells me I have the wrong device ID

I'm posting here as a last resort after spending a week on this forum reading on how to fix this phone.

Any ideas or is it toast?

I think about the only thing to try would be to reflash the shipped radio rom. You may need to find out what that 1.3-something actually was and reflash. May fix the problem.
No guarantees though s this is the radio rom and its a mongrel of a thing, causes the most bricks.:(

Good luck...:D

Was having similar problems with the radio. No GSM at boot up and could not access phone once booted. No matter what radio I try it gets stuck flashing at 0%. I took the sim out and rebooted the phone. It booted much faster and now the device id tells me this:
Operator Version: PDAviet.net
ROM Version : DVH_V27_BS
ROM Date : 10/30/08
Radio Version : 1.54.07.00
Protocol Version : 32.86.u.7020.23h
ExtROM version : Black(Basic).

Before with the sim installed I got nothing under radio version and protocol version. I can open the phone now but it says The sim card is missing.....Emergency Calls Only. I have been reading for days and days through the XDA guides and Wiki stuff and nothing seems to work. After a try flashing a radio and it gets stuck, I have to use mtty.exe and use set 16 0 to reboot OS. Every now and then the phone will not respond with mtty.exe and I use a sd card with a Splash1, Splash2 and OS only to revive the phone. What should I do next?
