[Q] Return radio to stock? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

So I was considering getting a T-Mobile prepaid SIM card and trying it out, so went ahead and flashed a T-Mobile radio to my Skyrocket. After that, everything in the phone info appears as "Unknown" - unknown baseband, unknown IMEI, etc.
I've tried flashing two different AT&T radios now, with no result. What should I do to return the radio to a working state?

OK, I finally figured it out myself, so I'll just leave this here in case it helps anyone else.
The problem was that the first T-Mobile radio I tried replaced several files in /system/ which were probebly from an older version of Android. This just broke the system's cellular stuff entirely. The solution was to reflash CM10.

HELP! Sprint Phone Stuck in Verizon Network!?

Whats up guys
I was trying to fix my GPS for the phone and was following a tutorial. I ran a verizon PPST.exe, which I believe update the PRI to a verizon one.
After this, I lost data and phone functionality. When I try to call out, I hit a verizon roaming message.
I tried hard-resetting, and I even tried reverting back to the stock sprint ROM.
Neither fixed the problem, even after I let customizations run. In device information, I have:
ROM: 1.03.651.3
RADIO: 1.03.15F
PRL: 51064
PRI 2.03_003

[Q] Sensation XE no signal on a Particular Carrier

Hi All! We've been working with this issue for 2 days at our help channel #helpmenow.
I currently have an s-off 1.27 hboot sensation XE running Insercoin v 2.0 ROM.
My issue is I don't have get signal for a particular carrier. (Other SIMs for other carriers works just fine). This carrier used to work before, I was just charging and then I noticed that it got no service.
These are the steps that I took so far:
1. Check antenna at the cover
2. Tried SIM on another phone (SIM Works)
3. Tried a DIFFERENT SIM from a DIFFRENT carrier, it works fine on MY phone.
4. called my provider but no issues on their side.
6. used RUU
7. tried RIL's
8. Flashed old 1.17 firmware to clean radio data.
9. Flashed a different ROMv with and without full wipe
10. Also tried downloading apps to enhance signal but to no avail.
we've been working this out with ganesh007, kgs1992, T-Junk, David_ and others on the channel but as of now I still got the same issue.
Hopefully you can help us figure this out so it could be of use to others who might have the same issue in the future.
PS: Right now I am using a different SIM from another carrier so as to get the phone function of the Phone. The carrier you see below my name is the one that is having issues right now.
Thanks in advance.

Kabayan, we are on the same boat. I have the same exact issue..Sensation xe(2nd hand), originally from Singapore(Singtel), went as far as going back to GB stock. At first, I thought it was just sim locked to Smart, but when I tried a Sun sim, it worked. At this point, I do not know what else to do. Tried cleaning s58,tried firmwares with different radio's, etc. After reverting back to GB and putting in a Globe sim it still says "Your sim does not allow a connection to this network" and no signal. If you got any updates, please let me know. Okay?

T-Mobile Sim on Skyrocket was working, now NOT recognized

Hi I recently received an AT&T Skyrocket and I unlocked it to use on T-Mobile and flashed it to Juggernaut/Faux009/VK1 and everything was going great.
I changed the ROM to SKY ICS, from http://forum.xda-developers.com/showthread.php?t=1602216 and only updated to D-9
I also changed the radio to the Blaze 4G.
I then started changing between radios to try to find the "right" one, I used Blaze 4g, UVLE. Then I started not getting any signal and went to check APN settings and I received the error "Insert SIM Card", but the Sim card is already in the phone.
I then tried to flash a bunch of different radios including the above and also VK1, and Telus radios.
Please, I need some help. What should I do? Do you guys need more info?

No Radio Signal

So I have been playing around with my Verizon S3, I have been swapping between different ROMS then all of a sudden my radio goes out. I now get 0 signal no matter what ROM I'm on. The odd thing is that I was switching in between ROMS that I had already used. I have tried downloading a radio but still no luck with that. Now I'm on a completely stock ROM but still no signal, any idea's? I also manually selected Verizon for the network. On some of the other ROMS it showed my number as something incorrect, now on the stock ROM it shows my actual number.
I haven't had the phone for more than 3 days, since I'm on a completely stock ROM and the binary is still at 0. Am I just best off bringing it into Verizon? Or is there some fix that I'm overlooking?
Thank you in advance for the help.

Thank you, I got my IMEI back but I still have no service. Just shows at a circle with a cross slash through it.

Have to try factory reset? if stills not working, seems like your SIM card is messup. Make sure you have stock rom, go to Verizon store ask for new sim card (it's free) and ask them to re activate it.

I just did a factory reset on the stock Verizon rom and I still had 0 luck, I'll go into Verizon tomorrow and get it straightened out. Thank you very much guys, this has turned me away from wanting to load ROMs a little
Edit: Just an update, I went to Verizon and they could not get my phone to accept a new sim card. Since I just got it within 14 days they had to give me a new phone because the other phone would not take another sim card and would not activate. I'm not exactly sure why this happened, I was just flashing between ROMs that I already knew worked.

[Q] Possible Sim overwrite?

ok more questions
SO everything was working great last night, right up until I flashed OTA jellybean onto the Phone
now it forces CDMA usage
Flashed back to stock 4.0.4 attempted to rehack the radio thinking that the updated re carrier locked the radio, well it didnt work
I am using a straight talk Sim and the Sim Serial is read correctly, only it Now ID's it as a sprint Sim
and the Phone type as CDMA
and the Phone Number is gone from the sim as well
the Phone Meid is also read correctly
Can a OTA flashed VIA RSDLITE REWRITE A SIM CARD?
I could make calls on my newly liberated phone just fine last night but now i can not after the 4.1.2 update
anyone else have this issue? any ideas how to fix?
