HTC ONE (M8) Dual SIM Not Receiving OTA Updates Anymore

[chshahid2k]

Hello All!

I have bought this device from Ebay, so i dont know what happened to it previously. But when I bought it was on Android 4.4.4 , it asked for the OTA Update for Lolliop consisting of 587MB (approx) and upgraded to Android 5 then immediately right after completing the upgrading process it again asked for another OTA Update (this time 57MB approx) and updated to Android 5.0.2 with 4.30.401.6. But after that its not searching for any new OTAs. I have heard that it official MM is available for this M8_DUGL but i am not sure. Can you guys please help me if i can officially update this device to MM Android 6.

The result of

I know the phone software has been modified in some ways as you can see SuperCID for this phone and ModelID is weird too.

I am also attaching the screenshots , kernel version is also there and device is unrooted.
