[Q] How do I get to the bootloader screen - Verizon HTC One (M8)

I tried getting to the bootloader screen on my HTC One M8. I turned it off, wait 5 seconds, then hold power down, and press power for 2-3 seconds, while still holding volume down. It never gets to the bootloader screen. It always does a regular boot.
Don't know if this matters, but I did root with WeakSauce successfully.

Haven't tried that yet. So there's no way to do it without plugging in to a PC? I thought it should work on the device too.

I believe you have to turn off fast boot in Settings->Power and then you can do it by holding the volume down and power buttons at the same time.

[Q] One S - Hard Brick?

I have unlocked bootloader via the HTCdev. Flashed Recovery. Take root. After that, the phone turn on normally. I wanted to enter fastboot, it just shut down - and nothing. Clamp the keys - no reaction. Battery is charged. Hold the power button longer than a minute - nothing. On charge indicator lights and nothing too.

My phone sometimes is completely discharged all of a sudden. Takes about half a minute of charging to get back being able to turn it on again, still connected to the charger. Maybe happened to you? Try connecting it to a powered charger and try turning it on again...

Can you get back to the bootloader screen? (hold vol down + power) If you can, you can get to fastboot and push a different recovery/kernel/rom/whatever you need from the PC (fastboot.exe probably will detect your phone if it's in fastboot mode).

No, when i hold Power (or vol down + power), phone doesn't do anything, screen doesn't light up, no vibration, no any reaction. So i can't get to hboot or fastboot.
Your phone is DEAD.. might be some issue with hardware
when you hold pwr and vol- for 10 secs or so, you must release power and keep holding vol-
just checkin since you didn't mention that
can you use fastboot commands
did u fix it?

There are problems entering HBoot sometimes. Try to enter it via your computer. Plug your phone into computer and use the command "adb reboot-bootloader" twice. You should get to the bootloader

wont let me get into bootloader. the power and volumes just keeps booting the phone up and stuck on infinite forclosing
happend to me a few minutes ago it was nasty try to shut down the phone and then
before it loops quickly power+volume down and after the one xl buttons stop flashing hold the
volume down and keep holding it until bootloader shows up
press and hold power button until capacitive buttons flash 6 times. then hold volume down. phone will boot into bootloader. carry on from there.
The problem is you weren't holding the right keys to get into bootloader.... and everything is fc'ing because your running codenames kernel on cm10.

thanks. but wow im an idiot. im so use to samsung phones i was holding volume up and down
This always does the trick for me Turn on, hold power 10-15 seconds, until screen goes black, let off, press n hold volume down, press power just 2-3 seconds, let off power button but continue holding vol. Down

To get into bootloader hold vol- while holding the power button. Don't let go until it reboots. It will now be in bootloader

You need to let go of power, but keep holding vol down. If you don't let go of power, nothing will happen (except the phone shutting off).
The most surefire way (works in just about any situation) is to hold power and volume down. Don't let go of volume down until I say so later. The capacitive buttons will flash after about 5 seconds. Then the buttons will stop flashing, the screen will turn off (if it was on). After that, release the power button, but keep holding volume down until the white bootloader screen shows up.
If the screen turns on at all, the phone will always be able to go to bootloader. Failure to get into bootloader is almost always a matter of the user not performing the button sequence properly, rather than an issue with the phone.

Phone stuck at Verizon loading screen, can't fastboot

Hi guys,
So my buddy rooted my phone for me and had me on lollipop. Somehow I connected my phone to my friends samsung fast charger and my phone updated normally, and now my phone is stuck at the verizon loading screen on my phone. I can't open the fast boot with the hard commands, (Volume down and holding power button). The only thing I can do is do the soft reboot with the volume up and power button. Any help would be greatly appreciated. I would be fine with doing a clean reset or even going back to stock I really just need my phone to be working.

When you do volume up and power you need to time it right to switch to holding vol down in order to enter boot loader. If you wait for the battery to die you can also boot into boot loader by holding vol down when you connect it to the charger and it gets enough of a charge to boot.

So whats the exact combination? You hold down power button and volume up and then switch to volume down when the screen goes black? Thanks for the help.

Yeah it does take a little practice. I've had a lot of practice at it now I seem to have that problem most often when trying to change boot animations, it will get stuck at the Verizon boot image and after about 5 minutes of waiting I end up doing this.

hard bricked my MT-TL10

Hi there,
Kindly help... I successfully installed B512 on my TL10 using force upgrade method, afterwhich I changed recovery to TWRP 3.0.2 using mobopx v2.2, which was also successful. And then I installed SuperSU 2.46 via TWRP, then cleared cache/dalvik. But upon rebooting system, I get a blank screen, even after waiting for more than 15 minutes.
And so I tried going to TWRP (Vol+ and power), which was successful, in order to boot to bootloader, with the intention of loading back the stock bootloader via adb, so that I can force install B512 from my microSD card again. It seemed to install fine...
However, at this point, I cannot reboot to bootloader (Vol- and power) anymore, I only get blank screen. Trying recovery (Vol+ and power) doesn't work either. Rebooting normally gives me the same. I cannot by any means connect via adb now.
Is there any way to unbrick my phone at this point?
Thanks so much. Cheers.

The phone "doesn't want to turn off" bro. It has fully discharged, but as soon as I plug the charger in, it immediately powers up. When it does, now it shows the Huawei logo. But it's stuck there, and if I press the power button for a few secs, it will power down, but immediately power up again...

Let it get fully charged first. Then remove the charger and keep the Vol up and power button pressed for ~10 secs or more, and see where it takes you.

Done bro. Although I must say, I'm kinda back like yesterday when the phone is just helplessly discharging until it drops dead. Pressing vol+ and power restarts the phone, but I'm still stuck at the logo...

You seem to be in a sticky situation bro. Your recovery seems to be broken because in stock recovery Vol up + power should ideally take you to recovery and not restart. If you could somehow boot into fastboot mode then it could open up some options to bring your phone to life.
With no way to connect to the phone the only options left are the hardware buttons. I am sure you'd have tried them already, but just in case you have not, try the other 2 key combinations also, Vol down + power and Vol up + Volume down + power, for ~10 secs, to check if any of these either forces a factory reset or boots the phone into fastboot mode.

Thank you for this suggestion brother. I tried exactly as you described, however, the phone looks badly discharged, and while the screen was blinking/showing the red battery icon, it doesn't seem to want to charge. I waited around 5 minutes, but nothing seems to progress from here.
And so now, I moved the USB cable to a proper charger, and now it seems to be charging, with the LED light a steady red, and the screen the normal red circle with "0%" inside. It seems to be charging at the moment, although I really have to wait until it shows "1%" until I can surely say so.
One thing that's different now is that the phone hasn't turned on (by itself) yet. And at least this looks promising.
I'll let you know what happens in a while... Thank you!
