    Okay, so earlier this week the latest marshmallow update popped up and so as usual I began downloading and installing it. I left my phone on charge, pressed update and left it. During install the phone restarted per usual but came to a black screen with a red triangle with exclamation mark (uh oh!).

    I searched online and found how to get to the bootloader. Tried rebooting several times but no luck. I went to recovery, cleared cache, rebooted and nothing happened. Then chose factory reset (I have a backup). still no luck rebooting. Followed many guides on how to fix it using TWRP and placing img files on sd card. Now my phone just powers on to bootloader every time. I can still get into TWRP and fastboot and such.

    I am quite certain that my phone has been completly wiped, drivers an all except the OS is still displayed in the bootloader. I just want my phone to be working again.

    HTC One M8 unlocked, current carrier: giffgaff (O2 network)

    images attached. couldn't rotate them.

    Please help ASAP

    You mention using TWRP. Was the device rooted prior to the update?

    Best solution I can offer right now is to install HTC Sync Manager and reflash the latest stock RUU via that.

    p.s. this is probably best posted in the HTC M8 sub-forum so that other users can offer advice. Let me know if you're happy with me moving it.

    Hi thanks for the reply.

    No I did this after the update failed to launch the phone (red triangle exclamation mark alert).

    I have HTC sync manager but I cannot get my pc to recognise my phone. Before, I would always have enter my passcode and leave the phone open whilst connected to the pc.

    If you could move this over to the HTC M8 sub-forum that would be great thanks.
