HTC won't boot - Desire 820 Q&A, Help & Troubleshooting

I tried to root my HTC Desire 820. While rooting it with supersu i checked reboot system instead of wipe cache/delvik (which is probably why it wasn't detected as rooted). I noticed it, so I went back in, and while choosing .zip directory i went away for ~5mins and now my phone doesn't boot (LED doesn't blink either); battery is well over 80% and charging. What should I do?

Reboot a couple more times, or is that blank screen caused by the TWRP screen saver?

Well if I had to guess I'd say it's a screensaver because I didn't really press anything; I can't access it in anyway, unless there is a special type of button combination?

Try holding power and VOL+ together for some times. It should then bring up the HTC boot screen. Then the device should start boot normally again.

So I guess Volume down doesn't work that way? I tried pressing vol- and power but it didn't work, haven't thought about vol+. Thanks a lot for saving my ass.

You are welcomed?.
For most of the Android device that has a non-removable battery (not by screws), VOL+ and Power button is a universal trick to force reboot/shutdown your device.

stuck on green htc logo with while background

This morning I tried to flash Blackout ICS Incredible. I am currently stuck on stuck green logo with white backgroud forever. I am using CWM touch recovery. I can not get to cwm, bootloader or Hboot menu. Only way i can reboot is to take out the battery. Once I put the battery in and let it boot, it goes back to logo screen and gets stuck. Then I took out the battery again and put it back it and press power button while pressing down vol- button, and it goes back to same logo screen and stuck. Again if i take out the battery and put it back it, and if I press the power button while pressing down the vol+ button, the phone vibrates 3 times and goes blank(dark) with battery indicator light blinking(i am not sure if that is battery light).
Any help would be appreciate. I am trying to connect to adb or fastboot, but it does not connect to the phone yet.
Pull the battery, wait five minutes.
Press and hold the volume down button, then press the power button. Don't let go. Wait.... wait, should go into recovery.
Full wipe.
Format data/factory reset.
Wipe dalvik
Format all partitions except sd card.
Restore a back up.
Then read how to get that rom working. Been posted too many times as for me to repeat it. Check the thread somewhere below yours, the title of the thread I believe is the same as the rom, answer is there.

Just saw the HBoot screen but lost it. What I did was, took out the battery, sdcard, SIM. Replace the battery but not the cover of the battery. Then I hit power and volume(plus/minus) button, the HBoot menu came up, but because the batter cover was not placed, the menu was lost when I did not hold the phone tight, meaning batter got loose. Now I am trying to get back to HBoot menu again after replace battery and cover but to no avail. I still have sdcard, SIM out of the phone. I think there is some combination of keys you've to press coming out from cold boot vs. not. will keep on trying unless someone already knows.

That is common flashing that rom. Choose full wipe in aroma installer even if you did it manually. When the flash is done, don't choose to reboot with aroma installer...DO IT MANUALLY from recovery!!...that should solve it...:good:
The same happened to me and found that solution in their thread.

I was able to get to HBoot, choose recovery, came up with CWM touch, did the wipe data/app, delvic, cache, did format /data, /* all the mentioned other than /sdcard. Then went to install from sdcard and choose that Blackout rom. went through the installer but at the end chose not to reboot from the installer as suggested. Then came back to CWM touch menu and did the reboot from there. It stuck on that logo screen again for 5 minutes. Now again took out the battery for few minutes, and want to go back to HBoot, but could not. Do I have to take out SDCARD as well, Do not think so but not sure. And why do we have to take out battery for so long, any idea, taking battery out for a minute isn't enough?
5 minutes just in case.
You missed one step. Wipe from aroma as well.

Should work without battery pull as long as you power off. But when it doesn't, battery pull.
Just volume down, the power, both pressed till it turns on.
Oh, and fastboot unchecked
Edit: if it stll doesnt work, could be a bad download.

If that doesn't work this straight booted bricked phone when nothing else would. Took 2 months of searching but I got it working within 5 minutes. It's from a thunderbolt forum but I think the commands are the same except for the img name.http://androidforums.com/thunderbolt-all-things-root/480350-easier-way-flash-pg05img-files.htmli was stuck with hboot s-on, no recovery whatsoever, security warning, no sd card, NOTHING.

After monkeying around with this ROM for a day, it was actually problem with CWM recovery. It looks like this ROM is not compatible with this recovery. I replaced cwm with 4ext recovery and voila I was able to flash this new ROM. Thank you guys so much for helping out. This community is really great to be part of.

I had the same problem after unlocking the bootloader on HTCdev. After a lot of searching, it seems that the HTC process keeps the boot partition locked from recovery but not from fastboot.
I was able to get around this by unzipping the Rom and flashing boot.IMG using fastboot and then flashing the Rom again.

[SOLVED] Possible Brick

I flashed @Fenny's deodexed m8 stock rom. During the flash the phone rebooted to the splash screen. Now the phone will not turn off when holding the power button. I confirmed the hash sum before flashing. Flashed through TWRP 2.7.0.2. Any help is GREATLY appreciated. I need to know how to turn my phone off (without adb since I'm at work). From there I can get back to recovery and restore the stock ROM.

Try holding the phone close to a light source then try to reboot it. Reboot it holding the Volume down key so it reboots into the bootloader.

Do you know about how long I should hold down the buttons? I have held it under a florescent light that is directly over my desk for a couple of minutes while doing that and it doesn't do anything.

It should happen after about 10 seconds. The reason for light source is because HTC doesn't want the phone to reboot in your pocket, etc ...

Whelp. Holding under the light source seems to do nothing. This is what I was afraid would happen if I bought a phone that didn't have a removable battery. :/ Are there any other methods that might work? I am downloading adb right now.

IDK that's always worked for me. Try holding the power button down harder maybe, I know it sits a little flush and you may not be pressing it down fully.
Great Success!!!
Okay. Finally got it to work. I had to hold volume up + power to get the phone to reboot. When the screen turned black I changed to the volume down while still holding the power button. This booted me to HBOOT. Then I was able to select recovery and boot there just fine. I am now restoring to my stock backup.
@SmiLey497 Thanks so much for your help! Your fast replies and explanation helped a lot! :good:
I think that I now need to go home and change my pants. Lol!
EDIT: Stock backup booted perfectly. No more paperweight.

Is my M8 bricked?

Ok folks, normally I figure these things out but this one has me a bit concerned.
I was in ViperROM HUB and installed a font package, it needed to restart in recovery to install, so I allowed it. I turned to my computer and when I next looked at my phone the screen is off and refuses to come on. When depress the power button I get a vibration feedback but the screen won't come on. I tried VOL DOWN and POWER but nothing is happening. Im gonna let the battery run dead and see if that will resolve it.
Has anyone encountered anything like this before?

Hey!
I dont think its bricked.
Ghost helped me out with my problem, see below solution.
Try holding POWER + VOLUME UP for 20 seconds and it should restart.
However my case was different I was stuck in HTC logo screen and no way to restart.
On the M8 it is Power and Vol Up to perform a "battery pull".

Thanks grega_slo and gaiden0000 for the quick response and spot on advice.
I did that before but it didn't work, it works now…guess I didn't hold VOL UP long enough.
Yeah I didn`t know about VOLUP either
It scared the crap out of me when I S-OFFed the device and was stuck haha

having the same problem. flashed cyanogen nightly and when it rebooted got to the splash and then black. nothing. none of the above methods seems to bring it back.

Put the usb cable in then press vol up and power until it restarts. As soon as you hear the ding on your pc press and hold vol down and power, you should then boot into hboot MENU.

never seem to hear a 'ding' or any other sound but no matter how I time it - power/vol up then power/vol down still results in htc splash then just black. Phone was quite warm (not quite hot) when I went to bed last night and this morning battery was at "0". When I first plugged it in and pushed the power button it alternated from the battery charging display to the TWRP locked screen but I couldn't seem to get it to stay on the TWRP screen no matter what I did. Now that I've used power/vol up I don't seem to get the battery or TWRP. just black or when trying power/vol up I get the splash. Power/vol down gives nothing - just black
EDIT: Just tried - let battery go dead. Plug in to computer hold power/vol down. Screen goes from battery icon to blank and back to battery icon.
EDIT: Pulled and reformatted sd card in Evo 4g LTE. Retried fastboot command still just shows "waiting for device". Even tried adb reboot bootloader and reply "device not found"
Could I use adb to reflash ruu? If so would the command be adb flash (filename)
Was beginning to lose hope of ever fixing this but a HUGE shout out to Simer03 who provided the critical piece of information - namely - add a ROM zip to your sd card. Hope nobody else ever has this problem but just in case
Post #4 here
Nothing is going to work unless you can either enter the boot loader or boot into the os.
You should still be able to access hboot unless that is corrupt. At the very least you need to hear the ding on your pc so you know the pc has recognized your device is connected.
Try again with vol up and power, hold until it reboots you should then hear that ding. If not check you have the necessary usb drivers installed on your pc or try a different usb cable.

Phone won't boot for 2 minutes after flashing rom

After flashing arhd 7.0, before hitting reboot button in twrp, my phone turns off and I can't get it back to life. I keep holding power button + volume up or down being in panic for a couple of minutes. After that my phone boots.I am not sure after what combination of buttons.This happened several times. Does anyone has any suggestions? I 'm afraid my phone won't boot again eventually after flashing a new update

In the twrp settings screen turn off the screen saver setting. I forget what it says exactly but once you turn this off that should stop happening.

Thanks I will try this. Hope won't happen again
I panicked after flashing AR7.0 as I thought I had bricked my M8. The screen goes black and doesnt respond, but I found that if you just leave it for a good few minutes it will boot up properly. It stays on the white HTC splash screen for a while too.
Happens to me too. I'm not sure if it's really the screen lock, but if you just leave it alone for a bit the screen will come back on and then you can tell TWRP to reboot.
First time i flashed and the screen turned off nearly gave me a heart attack

Flashed bad Rom while porting

I was attempting to port SlimRom for the Desire 816, and I stupidly forgot that the one m7 had a different screen size. As a result, the phone screen doesn't work. I attempted to reboot into recovery, except for that you need a complete off and volume complete off and volume + down. with no screen, all I can do is reboot. adb is no help either. Please Help me!:crying:

Once you see it power off let go of all the keys then quickly press Volume Down+Power and it will allow you to get into the bootloader. You can then proceed to the recovery from there.

Iv tried but it doesn't seem to work. I was able to drain the battery so it might work now
Update: I fixed it, the only way was to wait for battery to drain and then go into recovery...
