How i recovered IMEI and Baseband

Long story short.
Buyed a HTC One X from ebay with no imei no baseband problem. Took it at a local repair center and after a week thei didnt fixed. After that a realised that they S-OFF my HOX ) .
Flashed stock RUU and other 4 RUU-us but no awail. The flashed a wrong boot.img and i was in a bootloop. Managed to charge the phone through TWRP and then flashed and old CWM and a CM 10.1 nightly. After that with the phone booted i upgraded my recovery with ROM Manager and flashed a CM 11 Nightly. The dialed *#06" to see if the imei is showing ... but nothing. Then i decided to Factory Reset HOX again and WOW my imei and basend were there Now my HOX needs to be sim unlocked and ready to go.
Hope This help many of you because i saw a lot of people in this forum complaining about this issue.
Thanks for the time and excuse my poor english.
Can you provide more info please? What is your cid? Do I need to be s-offed to get this done?
There is no way to get to factory reset if you already wiped your whole /system I guess? Because that's what you do when installing a new ROM....
Mobile repair center made s-off to my hox.
So the only way to solve this is if we are s-offed...?

Check if the variant of the ROM you flashed matches with your phone. If you already checked it double check it. Try redownloading the ROM and flash it again. Hope it helps!
