[Q] Cell radio wont turn on

[gametstr]

Hi all

I dont know why / how but my cell radio suddenly went off and wont turn back on.
I am rooted BL unlocked on Nottachtrix 1.3.1 ROM.

I am also SIM unlocked and I live in India. I have the AT&T atrix.

What might have caused the issue
I was messing around in *#*#4636#*#* with the radio band.
I had this signal boosting app which I use but cant find it on the market to link it now. I 've been using this app for a while so dont know why it would mess up now.
I am not sure if these are what caused the issue but just letting u know

Things I have done so far
Battery pull
Different sim card / different network
I tried flashing the ROM again with full wipe but still no luck
Flashed CM7 Ba2tf and the problem persists.. can I rule out that it is software related?

Everything else is working fine.

I am out of ideas and help is very much appreciated.

Thanks

SOLUTION
The Easiest Fix for this issue is Flashing the right baseband in CWM recovery.

The radio is flashed separately from the Android os. Try a new baseband. However be sure to get the right one for your phone.

Issue solved. I 'll detail what I did so it can help others.

Yes. Selecting the USA Band is what caused the issue.
I dint know that basebands could be flashed on Atrix ROMs. I wish I 've known it sooner. Would 've saved me a lot of trouble. Anyway I went with the SBF method.

I had the 4.5.91 earlier but I went with 4.5.141 to be safe.

Everything went smooth but at the end RSD lite said "Please manually reboot this phone" and the phone went into a boot loop at the M logo. I looked around and after a while found that a Wipe fixes it in stock recovery.
1. Disconnected the phone
2. Pulled out the battery.
3. Rebooted and went into stock recovery.
4. Wiped data and rebooted.
5. Got to home screen fine. Rebooted once again to make sure everything is fine.

Then inserted sim card and I had a signal. Everthing is working great.
