[Q] {HELP} Phone won't boot and can't get into Recovery - One (M7) Q&A, Help & Troubleshooting

Hi everyone,
Has anyone seen this before? When i turn my phone on I get as far as the initial HTC One splash screen, but no further. it just hangs there.
If I try boot into recovery I see the recovery screen flash up for a split second, then the screen goes black.
I can get a FASTBOOT connection, and so I flashed another recovery - but the same issue in that the phone won't boot, and if I try access recovery, it flashes up for a second then the screen goes black.
Anyone any ideas...?
Cheers!
Arran

Just a quick FYI - I managed to sort this by following these instructions:

Hope this helps anyone else having issues!

Stuck in Bootloader screen

Hello all,
as the title says, one of my touch diamond's is stuck in bootloader screen.
I didnt do anything in between it working and not working, it was on my desk, put it there working, got it 5mins later, and it was in bootloader screen (tricolor screen).
What i've already done to try and fix it:
flash it with the original HTC rom, flash completes succesfully, phone reboots to tricolor screen, so no solution there.
install mtty and format the phone, this completes, reboot the phone, again goes to the bootloader.
reflash the phone with original rom after cleaning it with mtty, flash again completes succesfully but when it reboots after flashing it just goes to bootloader again.
Tried to flash a Hardspl: stuck at 0% and stays there. so that doesnt work.
BUT! when in mtty i give the "boot" command, it DOES start to boot WM. but then again, when i turn the phone of, and on again, or it reboots because of first start after flash, it goes to bootloader again. The VOLDOWN button is NOT stuck, cause when it boots i can use the vol buttons perfectly fine.
Anyone got an suggestion in how to unbrick it? i have a second, perfectly working diamond here too, if that helps in any way.
Some more info ive just seen in mtty, when i told it to boot, it said ONE BAD BLOCK IN CE, remove block ---- to ---- (dont know the exact numbers anymore)

[Q] Cant get into recovery, Logo graphical error on boot

Hey guys, I'm having trouble with my nexus device, I was watching youtube on it and it froze and now doesnt boot. I can access hboot, but recovery just shows the X logo and restart. I've tried reflashing boot.img, reflashing the recovery, reflashed stock hboot, flashed new roms from fastboot. I've also tried passimg.zip, and flashing a different radio but it stops 90% the way through, and it gets stuck in loading passdiag.zip if I use the volume down button to boot instead of the trackpad button.
The graphic abnormality is like an artifacting. If you search youtube its called "Nexus one stuck on X, can't boot to recovery.", I cant however post a link.
Anyone encountered this before? Any insight is appreciated.
well I've managed to remove blackrose at least, and to get to the blackrose menu. You have to access it from command prompt with "blackrose.exe skip" while in fastboot. Though I'd put it here incase it helps someone else in a similar circumstance.

Phone will not boot regularly or into recovery

I am having quite a problem. I had unlocked the bootloader and rooted my ONE. Suddenly it decided to freeze on the lockscreen so i tried to reboot. It would not reboot and was stuck on the HTC ONE screen. I tried booting into recovery and sideloading the stock rom which did not work. and now i can not even boot into the recovery. please help. When i try to boot it up regularly it gets stuck on the Quietly Brilliant screen.

This will sound weird but seems to be helping people in the dev sections:
Put the phone under a bright light, and hold the power and volume down buttons.
I haven't had to use this particular method myself, but supposedly it works.

Can't install/wipe anything (rom, recovery, ecc).

Hi everyone.
I've android 6 stock (xt1068), and today i woke up and it doesn't work
I try to install the twrp and then to flash rom, ecc, but after that i install the twrp succesfully, when i go in the recovery i see that there is no twrp but the main stock recovery. This thing basically appens with everything that i install/wipe, infact the bootloader tells me that my action worked, but it didn't.
Another thing is that if i let my phone boot up, after the boot animation it tells me 'Starting Android', then this text go out, and for a second the boot animation appears again, after that all the screen goes black. (The phone is not closed, but it is showing black in the screen, i think you got it)
Thank you

Note 4 Wont Boot (Really need help with this one)

My dad dropped and cracked his Note 4. I need to boot it up to get the data off it.
For some reason it wont boot to recovery, it gives me the blue text but it just boot loops after. I cannot get it to boot to the OS either.
I can get to download mode, i already tried flashing the firmware through odin. After doing so, it goes to recovery to install the system update, but then freezes 1/4th the way through and boot loops again.
I cant flash a custom recovery because the FRP lock stops me.
The only thing i have access to without a problem is Download mode. Can anyone please help me get this thing booted so i can recover the data?
Thank you!
