[Q] blank display, but can adb shell - HTC One Max

today I re-S-ON, removed tampered and disable logcat.
after 9 hour, my phone suddenly got blank display after I woke up from sleep, all the button not functioning.. tried to call my phone from my another phone..call came through but I can't pickup, can't reboot.
but I still can access my phone through adb shell.
reboot command in adb shell wont reboot it,
adb reboot / adb reboot bootloader also wont do anything.
any suggestion guys?

Hold both volume buttons with power button until back and home buttons lights flash. It will restart after that. Happened to me a few times.

im running cm7 alpha 3. this is the first time i left it in sleep for more than an hour. now when i turn on the screen, i cant do anything. all the hardware buttons still work. long pressing power wont turn it off. adb is not recognizing it so i cant do adb reboot. unlike my phone, i cant just pull the battery. what can i do to get it to reboot?

Hold the Power button and the home button at the same time for about 10-15s, and it'll reboot.
that worked, thank you.

I think I broke my phone.

I was messing around with the wifi tether app built into the custom ROM I'm using (hatka 3.0), and suddenly my phone froze and now the display wont come on. When I hold the power button all 3 buttons at the bottom flash on and off.
USB reads it fine, adb as well.
Keep holding power down a few seconds after the buttons flash and it should reboot. If not, also hold volume down and you'll reboot to bootloader and can enter recovery that way and reflash if necessary

Neither of those worked. If I hold the power button, the 3 buttons will flash as long as I hold the button.
What happens if you keep your phone plugged in to the wall and you try to reboot/boot into the bootloader?
Also worth a try using adb to reboot into bootloader
Did you try removing the battery for 10 minutes ?

Plug the phone into your computer, make sure adb is working by running the command " adb devices"
If your phone is recognized type "adb reboot bootloader" and see if you can get into the bootloader that way.
Otherwise, I would keep it charged and try to get it to power down by holding power for about 15 seconds untill it powers down.
If nothing else works I would try removing the sim and try restarting that way.
Maybe even let it die then charge it up and try powering it on. If none of that works I would say you may have a fried display.

I have been in similar territory a few times. The holding down power button until 3 icons start flashing WILL work- the time held will vary GREATLY! from 10-15 seconds to waaaay longer, keep trying, multiple times if needed. It will eventually reboot. You may need to hold the down vol button to get into fastboot then recovery so stay alert when reboot happens-it usually does when you least expect it. All of a sudden, a black screen then you need to hold in the vol button to get back.

It's a non removable battery.

help phone died and will not power on

please give some advice. my phone died while receiving a text and i plugged it in to charge it displayed the red light that it was charging and then i pushed the power button to turn it on and it will not boot and it will not display the notification light that it is even charging. i was running the google edition 4.2.2 and had used htc unlock about a month ago and i haven't flashed anything since. if this helps i was using firefox a few days ago and it froze so i held the power button to turn it off and it took a good ten minutes and multiple times of holding the power button to turn back on. is there a power reset or something i can do since you cant remove the battery in this phone?
Plug phone into charger
Try holding down power and volume down until
Keep holding down, you'll see the back and home buttons light up. The screen should go black and then eventually go into hboot
From there you can reboot or go to recovery and reflash or do whatever

i have tried all button combos and nothing not even home and back lights come on. i have even left it on the charger overnight and still no notification light came on. i did get in indication when i plugged it into my computer so i might try a ruu if i can. thanks for the help though.
not sure exactly how but i now have my phone working again. windows recognized the device being plugged in so i installed htc sync for the driver to be installed and then i did a 'fastboot devices' command and it showed one device connected so i did "fastboot reboot" command and then checked for devices and nothing was there. then it booted while holding power + vol down
what hboot ar eu on?
help me

I effed up again....

Sooo.... HDX 8.9 Saturn... Rooted using Kingroot, and Disabled OTA... and the home launcher... so I'm at the point where windows explorer opens up the kindle, but i don't see anything because I had a password on it, and ADB won't let me install a new launcher to fix my mistake... Does anyone know the fix to this or can point me to the right path?
I guess your one option is hard reset from stock recovery.
You need working adb. I suppose after the hard reset adb access will appear. But no guarantees.
Will that not disable adb anyways?
I said: "no guarantees". but I dont see other option anyway.
Can't get into recovery... What are the buttons to be holding... Vol Up + Power, right?
Just hold vol up immediately after power on.

Right I did that, got in, but it cycled out almost instantly... I tried a few more times, and left it alone.. now it won't respond to anything, not even when I plug it in... argh... Looks like its permanently dead.
i dont think that this is possible
try to leave it in charge or hold power button long, above 3 min.

just clarifying, hold vol up immediately after power on, without holding power button.
I left it on the charger overnight, and now it won't respond...
That is how I got into recovery, then it cycled out... I tried to go into recovery with only the volume up, and it wouldn't let me, and then this happened....
i'm going to hold off until Saturday, and leave it for about 5 hours on the charger... See if that does something
Yeah, so I left it in the charger overnight, and there is no response no matter what button combo I do....
so what the heck happened... I didn't do anything in recovery, unless it did something when it flashed out...
Well, I finally did the factory reset... I have the notification panel and the home buttons panel... Settings doesn't work, neither does wireless, and I have a flickering screen.
Amazon said they will send me a new one...
Search Partially works, except that I can't really turn on wifi to download an apk or turn on ADB using the option... wonder what would happen if I tried ADB now... not much point anyways since I'll get a new one, just loose root.... I can live with the new UI

Turn off without screen

Hi
Crushed my screen and need to shut down the phone. Anyone know what to do?
Screen is currently not working at all, just showing some blue spots.
Pushing the power button for 10-15 seconds just make the phone restart.
I have also tried to shut down with various modes of Volume +/- while pushing power button, no luck.
Anyone have an idea here?
Appreciate anything.
Thanks.

If you can get adb running you could always run (in cmd prompt) :
adb shell shutdown

Not possible, the screen is completely inactive.
Need to find the "button" to push for 20 seconds so it gets turned off, not restarted as it does now.

Ok. When booted, plug in usb from computer.
Hold power and volume up until phone vibrates, release Power button.
Keep holding volume up for about 20 seconds (this should be a lot faster with bootloader locked) then release volume up.
Wait for another 10 seconds to be safe.
(If you hear it connecting to computer it's not actually done booting to eRecovery yet)
Now, click on Volume down twice, then power. Device should now shut down.

Excellent, thanks.
This seems to have worked, are no more blue spots left on the screen, so believe it to be shut down.

just wait until the battery dies
