Why am I getting a Tampered warning?

[AC Question]

Tampered warning

My HTC one M8, bought new two days ago from a mobile shop in box, worked for eight hours after all updates, now keeps restarting and can't get to the main screen, I have'nt even touched the settings.

Tampered
Locked
Security warning

The options it gives me is
HBOOT
RAMDUMP
REBOOT
REBOOT FASTBOOT
POWER DOWN

I have tried all of these and none of them solve the issue, even HBOOT/factory reset, this didn't work.

Help, five days without a phone, getting withdrawl

Thanks,
Craig

P.S. didnt have an issue in three years with my galaxy s2!

Re: Tampered warning

Welcome to Android Central! So was this a used or refurbished phone? A "mobile shop in a box" doesn't sound like the most reliable place--it sounds like they may have sold you a used phone, which can be a problem if it was rooted and modified by the previous owner, which then possibly caused these problems. What's the shop's return policy? If you just got the phone, it seems that you ought to be able to return or exchange it.

If you can't, see if you can wipe the cache partition by following these steps: http://forums.androidcentral.com/ht...ow-reboot-into-stock-recovery-htc-one-m8.html

If it says tampered, it means something was unintentionally changed at the very core of the software installed on your device (kinda like the bios). Go into fastboot mode and connect it to a PC. See if the phone changes from "fastboot" to "fastboot usb". If so, that will open more doors to find a fix for your device.
