Help, I bought a z600 from ebay. it was an unlocked T-Mobile phone. I had it working when I got it on my ATT/Cingular system. I flashed the gdfs and firmware to get rid of the T-Mobile stuff. Now when i check the >*<<*<* SW stuff it has GSM900. It is supposed to be 900/1800/1900. So I cannot recieve any signal over the att/cingular (I have a T616 that is 850/1800/1900 and that works fine. What did I do wrong and is there anything I can do to fix this?
Aside from sending it back to SE with 150.00 standard flat rate repair fee.

Greetings friend,

What files did you flash and what Service tool used?

GSM bands are stored in hardware so no way you can screw it up unless you have a hammer.

Please tell me exactly the files, maybe you used DIV xxxband build by merwin.

HI, Yes well, It had to have been some kind of software. But the crazy part now is that I did a SP repair, (The chip that knows what the phone is supposed do) And it works great, the phone now says 900/1800/1900GSm where before it was only 900GSM. All I know is that I put that evil cable up on ebay.
Thank you for your reply.
I dio appreciate it alot.
