My M8 HK Stopped reading all Sim Cards after Sim-Unlocking it!! Pls Help! topic

Hello my friends, I was wondering of any of you can help me out with this, im at a loss on what to do or try next. Anyways heres what happened: I bought a Sprint M8 HK Edition to use overseas, it came with Android 4.4.4 already installed and the latest 3.19 Hboot. I proceeded to unlock the bootlader, install TWRP and rooted it. Then I achieved S-OFF with sunshine. Then I installed the latest 4.4.4 BadBoyz rom and procedeed with the sim unlocking method (with android terminal emulator) and all went perfectly fine. The sim unlocked correctly and I was able to use my foreign sim card in it to make calls and access data. Well, I then did a factory reset of the phone, and when it booted up again it wouldnt read the sim card again! I have tried several sim cards, including the original Sprint sim card that came with the phone and nothing. I have tried reinstallin the badboys rom and no go. I went back to stock with the latest official RUU and no go. The sim card reader is completely dead. Im really at a loss on what to do next. I cant beleive that a simple factiry reset cand ruin the simcard reader like that!

ANy help or suggestion on what to try next would be really apreciated!!
