Hi,
I am using CM12 nightly memul with TWRP 2.8.5.0 and now have trouble booting my phone. I turned it off and charged it overnight. Next morning the screen showed the "empty battery sign" and I could not boot.
I have yet tried to press the power button under a bright light and to somehow reboot it via adb and fastboot. I would now like to seek your advice in this matter, please.
With kind regards 981475165

You can forcefully reboot it by holding the Power and Vol+ keys for about 10-15 seconds. It should boot normally then IMO
Thank you very much. I did that before but the battery must have been too low, because at that time it didn't work.

Note: This is a re-post from the Verizon HTC forums (http://forum.xda-developers.com/showthread.php?t=2533042)
I just rooted and S-off my HTC via rumrunner.
No flash roms install or custom recovery installed.
I wanted to see if I still had CWM from my last root (I returned to stock via http://forum.xda-developers.com/show...highlight=s-on.
So I went into the bootloader or fastboot (I don't remember) and hit recovery. This did not send me to a CWM, but it appeared to be the stock version of recovery. The process took too long (I know impatient) so I turned it off via power button + volume down.
Now I come to you in need, my phone is constantly turning off/on only displaying the green htc text, no red text, then pausing for 8 seconds, then off again to black screen. The whole process lasts 12 seconds, and this had been going on for about 10-15 min atm.
Plugging it in, my computer does not have the time to recognize it with adb, or fastboot.
I cannot use the power button + volume down to go into bootloader, and pressing the power button does nothing.
Please help me.
So here's the update.
Screen is now black, meaning the boot up/down process has stopped.
I have tried these:
A. Hold down the volume down + power button for 20+ seconds.
B. Hold down the volume up + volume down + power button for 20+ seconds and let up on the volume up button when screen goes black.
These two methods results in a single boot up to green HTC text then black screen.
I suspect the device has lost most of its power. Tried it for a third time, the device is now unresponsive and remains at black screen.
Now I plugged the usb cable connected to the power adapter.
The device enters the aforementioned continuous boot loop.
I tried method A and B, and there are no results, the boot loop continues. Now the device returns to the low or no powered state.
Now the device is connected to the computer. The same happens as if it were connected to the power adapter.
Method A and B still do not work.
Results: holding down buttons longer do nothing for me. The device seems to have lost power, but when charged, immediately the device enters the boot loop state.
Note: when doing method A and B the trials were done when screen is on and when screen is off, still no results.
Now the screen is off and not connected to anything. The problem still persists.

If I had to guess I would say your volume down is broken, else it would enter hboot
plug in the power and let it charge all day. then plug it to your pc and try to adb reboot bootloader or adb reboot recovery the instant you here the pc usb ingage.
once you get to the bootloader try and fastboot erase cache followed by fastboot reboot
after your phone boots you should be able to go back to bootloader and reinstall custom recovery

I have a few questions/concerns to this.
1. When I charge it, I can't stop the phone from the continuous boot. I'm afraid that doing this all day might hurt the phone more.
2. Currently I have been charging it via computer (still boot loop), and the computer does not recognize it at all. I think there is really not enough time because the loop duration is only a few seconds.
3. Since the phone is connected to the computer, the commands adb reboot bootloader and adb reboot recovery does not work. Error: device not found.

So what is this method supposed to accomplish?
I did this and the phone stopped the continous boot. However when I tried to go to hboot it went back into the loop. I did this twice, and I'm able to stop the loop with the bright light method, but I don't know what to do from here.
Note: when plugging phone into computer, the loop starts again.

the phone should not bootup with the power cord plugged in from an off state (are you turning the phone back on ?)
turn off phone by holding power 15 seconds under a bright light
plug phone into outlet (not PC) let charge till green light comes on (not Red)
hold volume down and power for 10 seconds ( you should be in hboot)
plug phone to PC choose fastboot hit power
your now in fastboot usb
from here you reflash recovery
fastboot erase cache and reboot recovery
if your still in bootloop I'm at a loss, and seems your hboot is corrupted I think you have to return your phone to Verizon or HTC.

Well I don't know if it is truly off, I'm just assuming it is.
But yes as soon as I plug the phone into the power adapter the red led flashes on, and the htc logo appears, then the loop continues.
I'll probably take it into Verizon tomorrow and update on what happens.
Update: Welp, I gave up. I'm going to get my replacement soon and I'll be turning it into Verizon. Really it's not that bad of a loss since I just wiped the phone, only thing is I lost my screen protector and carbon skin

sorry to hear that mate!!!
Unlocked bootloader on my phone no problem so decided to go on to rooting. Followed the xda video step by step, but using twrp as recovery instead of clockwork. Flashed twrp using fastboot. Instead of hitting reboot bootloader, accidentally hit power down. Device is now stuck on charge screen, even unplugged. Charging LED unlit, cannot power down/reboot. Anything I can do, or have I bricked the device?

you probably have flashed twrp 2.7.0.0 which have this issue with charging mode (phone plugged and powered off but the screen will never turn off)
Hold down power button + volume down until the phone reboots then flash twrp 2.6.3.3 or 2.6.3.4 and you'll be fine.
I installed the latest firmware for my device using fastboot to do firmware only and not the full RUU. Now am having a strange issue and was curious if I could get some help. When I power off the phone and plug my charger in it displays the battery with the lighting bolt and flashing LED. What is strange is that the battery icon will stay the same and the LED will flash and the only way I can get it to release from this mode is by holding the power button down until the home and back button stop flashing at the bottom at that time the phone will go blank and boot fully. I would like to leave my device off at night and still charge so any help would be greatly appreciated. Currently running T-Mobile HTC One with Venom Rom and ElementalX kernal.

do not reboot phone with USB cable connected.
use power+vol up to reboot
are you using HTC orginal cable???
Do you have the USB Debugging enabled ?
original cable, debuggin not changed becausa frash rom flashed....I solv it with volume- + volume+ + power=shoutdown
I'v installed the last stock firmware.
Now there is another problem: the phone is completely drained, put it on charge, and after a while I displayed a black screen, with the logo of the battery in the middle, and bottom of the red "This build is for developement purpose only .... ", red LED flashing. Cut the cable, it will not budge from that screen, compelled to force a shutdown (volume keys + power). Then boot normally.
How can I avoid this problem?

you recovery might be corrupted. re-flash. i advise TWRP.
charge phone when off for a while the remove cable and turn it on.
if LED its flashing, it means its not charging.
The problem happens only when the battery is fully discharged. When I connect it to the charger, the LED flashes, and appears on the screen the logo of the battery and the red lettering at the bottom. Then, after a while the charge, forcing poweroff the phone with volume buttons and power, and the phone will restart correctly.

We agree that you intend to solve the problem, but till the time a solution is not found its advisable to keep the phone into ultra power saving mode at 15% or 10%, this will give about 8-15 hours of time to find a charger to charge your phone.
For me I have never let my phone die out of charge and I don't have a charger with me every where.
The only way to know if this is a recovery problem, which I doubt, is to flash the stock recovery and stock boot and check.

HELP PLEASE!!
I tried to flash the TWRP-Recovery via Odin following this instruction:
http://www.droidviews.com/root-galaxy-tab-a-10-1-wifi-sm-t580-2016-and-install-twrp-recovery/
instead of the XDA-instruction since it contains some pictures and everything was o. K. till I made step 9 and disconnected the tablet when I received the message from Odin "PASS".
Unfortunately this tutorial forgot to mention that I have to wait until also "the progress bar on phone should stop" as it is mentioned in the tutorial here on XDA:
http://forum.xda-developers.com/galaxy-tab-a/development/recovery-official-twrp-gtaxlwifi-galaxy-t3437666
I know I am a fool since the tablet clearly states "Downloading... Do not turn off target" and the progress bar is very close to the end but was not complete. Now this message is frozen on the screeen and I can't go back or forth.
I tried to restart the tablet normally and into the downloading mode, I tried also to reflash the TWRP-image with Odin but Odin does not recognize the tablet being connected. I tried to remove the battery (how? I can't open the tablet, also Youtube didn't help me).
Does anybody has an idea for me? Should I wait until the battery is completly drained so that the tablet automatically turns off?
Please, please, please help me since this tablet should be a gift for my wife and no I fear to have bricked it forever.
The tablet is (was) running Android 6.0.1, Kernel is 3.18.14-8761055, Build is MMB229K. And I also noted T580XXU1APG1.
Hold power and volume down to reboot, then quickly switch to holding volume up, power, and home to boot into twrp

Thanks - this combination lets me leave the DOWNLOAD MODE screen :good:!
I could reboot into recovery and - WOW - TWRP was installed properly!
I could now flash SuperSU-zip and thus my tablet is now rooted.
