No Sim Card error / Camera has stopped unexpectedly

Hello All,

I am on Sprint HTC One M8 (831C), was install with 5.02 - RUU H/K exe, S-OFF, using the GSM Carrier Vodafone- India.

Four days back was roaming out from my state in Mumbai, while in flight I kept it in air plane mode, the phone felt down and the problem emerged.

NO sim Card, also the phone's camera has is not working. I unlocked the the bootloader, installed twrp and swiped the Bad boyz Sprint ONE M8 Lollipop HK v3.2, assuming that I may resolve the issue but no Luck.

I have tried the sieempi.eu tick, also from settings but it says that your phone will switch to CDMA mode.

Further in Setting>Mobile> it says "there is no SIM CARD on your device. Your device will switch to CDMA mode"

Request all to suggest some workable solution please...

Regards

Karan Adhikari
