HTC One M8 stuck on bootloader

[VMKDF]

hi, thanks for letting me join. if this is posted in the wrong place im very sorry. My HTC One M8 is secondhand and Ive had it for about 1.5 years now. the other day it crashed and ended up in a boot loop. i have tried lots of stuff but to no help. is there a way i can load stuff on to the sd card to fix it. on two occations it has got to the setup screen but errors would not let me type wifi password so had to hard reset.
ive tried hard reset
ive tried recovery
ive tried wipecache/factory reset
ive tried factory reset......seemed to work on two occations but on setup came back with sense input error and google error.
the phone had all the newest updates and was unlocked to any network.
on bootlader its says....SOFTWARE STATUS MODIFIED
LOCKED
SECURITY WARNING
THEN LOTS OF GREEN WRITING.
any help would be great. thanks

You can follow this post instruction ( skip the part of relocking bootloader )
https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6


easy way :
Download the RUU.zip from the linked post and rename it to 0P6BIMG.zip then put it in your external sd card root and reboot to bootloader ( hboot )
It will ask you to update confirm it and wait for a few minutes till it finish and ask you to reboot,that's it

you can't flash RUU in recovery mode !!!!!!!!!!!
you tried to flash using sd card ( formatted as fat32 ) or the fastboot method ????
you said earlier your bootloader is locked
if it's unlocked relock it

 

[VMKDF]

Sir you are a GOD!!!!!!!! Phone is back to normal.
I followed your instructions and my M8 is now back to normal.
Thank you so much for your help and time. You saved my phone.

Thanks again

htc bootloader info

Bootloader info is great. But if you are asking for help, you really need to tell us more about what is going on with the phone. I gather from the subject of the thread, that your device is stuck in bootloader. But how did it get to that state? Did it just happen spontaneously (while using the phone, or when you tried to turn the screen on after idle for a while, etc.?). Or were you trying to do something, like unlock bootloader, install custom recovery TWRP, root, flash custom ROM, etc. Or some other function, like install an OTA update? If trying to flash something, provide exact details like version numbers, file names; as well as exactly what happened when you tried to install (changes to status of phone, error messages, etc.).

Have you tried anything so far to resolve the problem? If so, describe exactly what you tried, again with any applicable file names, version numbers, and outcomes (error messages, etc.).

The more specific details you provide, the better we can help you.

Stuck can't get phone to connect to PC

Hi, I have an HTC One M8 which I just got secondhand, it's stuck on bootloader screen, usual messages ('modified' 'locked' etc)... I followed the instructions for RUU flash on other posts and am all set to go, but annoyingly my phone will not connect to any PC I use....I have installed the drivers etc...I am well used to using ADB, just can't get the phone to be recognised.

I also can't boot into recovery, just ends up back in the bootloader screen again. If it does try and boot it hangs at the logo screen....

Would welcome some ideas on where to go next....

adb won't work in bootloader mode, by definition. You want fastboot for running RUU, which is related to adb, but with important differences.

As long as you are in bootloader-fastboot mode (fastboot is highlighted near the top of the bootloader screen) which is often default if phone is connected by USB, you should be able to use fastboot. Try the command:
fastboot devices
And as long as the phone's ID is returned, you should be good to go.
If the command just results in "waiting for response" or an error, try a different USB cable, or a different USB port on your PC.

 

[GitManMatt]

Still no go... Tried connecting on different ports and with different cables but just doesn't seem to work. Best I've managed is with the Aruuwizard tool which seemed to connect but I couldn't get much further. If I run fast boot devices it returns no device... Just a blank line....
