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/showthread.php?t=2475216&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 the problem still persists and I assume it's going to keep turning on and off for a while.
I'm just going to wait until the battery dies and see if it can charge and turn it back into bootloader. I'll report back on that.
On a side note in the case that this is bricked, anyone recommend any future phones out there better than the one with verizon? If not I'm probably just going to stick to this phone.

Hold down the volume down and power button at the same time, until the white hboot menu appears.
This may take a good 15 seconds or more, keep holding them down until the hboot menu appears.
Sounds like you aren't holding down long enough. If that doesn't work, try both volume up and down and power all at once.
Then when the screen goes black, let up on the up volume key, so that you enter fastboot via volume down and power.
Then you should be able to fastboot flash whatever you need to get back up and running again.
I wouldnt just let it keep looping until it dies though.
Probably won't damage anything but I doubt that it's real great for the device.

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.

leave the phone charging for at least 10-15 min on the AC adapter. press and hold both vol buttons then press and hold power for 2+ minutes. after 2 minutes, let go of all buttons except volume down. success?

actually doing that will destroy the battery. well maybe destroy is too strong of a word but it will damage it for sure. this is a very useful site for anything battery...

I actually tried the 2+ minutes because I saw someone had success with another phone and they said they did it for 3 1/2 min. However it did not work.
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

Hi
My Nexus 7 recently ran out of battery and as per usual, died.
When i plugged it into the charger, I thought it would charge and be ready to use again.
After several hours, nothing happened. No display saying it was charging, nada.
I then went to power it up into recovery mode, by holding down power button and volume down.
This then seemed to 'reboot' the system and I now see a droid with a red triangle and the words 'No command'
Having a look around online, people have suggested holding down power button and volume up.
Whenever I do this, the screen goes blank, the Google logo appears then the same droid with a red triangle appears.
I cannot seem to get past this step.
Has anyone come across this before and if so, how I do I get past this and actually use my Nexus?
Thanks

It's a little tricky actually. You shouldn't have to hold the power + vol up buttons for very long. The most important thing is that you have to make sure you push them at the EXACT same time. I kind of figured this one out on my own when I was having issues flashing a custom recovery.

When I press them at the same time, the only thing that happens is the screen goes slightly darker (i.e the icon becomes less visible)
I've pressed the buttons together so many times and nothing happens.
I tried to get back into recovery mode using a bootloader from androidrootz.com. I managed to get back to the step where i can select 'Start, Recovery Mode, Power Off' etc I ran 'Recovery Mode', which then rebooted and I go the same icon. I can't seem to run the program again though, so I'm still stuck with the lying down droid

Were you completely stock when this all happened? What bootloader from androidrootz.com? If you can flash a bootloader, why not flash the factory image?
Sorry, charesa39. Just as you'd posted (I'd posted same ). I'll just add it can be tricky. Maybe try power first then continue holding while hitting vol +. You do this when you're at the fallen Andy screen.

I also had some problems to access recovery. Finally it worked after many tries. So far i remember you have to press the buttons not too short and not too long ;D... perhaps 3-4 seconds. Then Release one of the buttons and the second one half a second later. I don't remember which button i released first, but there are only to possibilities. Hope this helps... in my case the recovery appeared.
So I got an HTC One second hand. Listing just said user reset it and started bootlooping. Got it for cheap so I figured I'd try and fix it.
Got it, and plugged it in (dead battery). The charge light indicator turns on, and the screen turns on with the charging animation, but only for a split second. Then it goes to the splash screen for about 10 seconds or so, screen turns off for a few seconds, then right back on and up to the splash screen.
Tried holding the Vol down to get into bootloader, but so far no good. The only way for it to stop the loop is for the battery to die. When I plug it into an outlet or a computer, it immediately goes right back into the boot loop.
So, is there anyway to save this? Or am I SOL?

Thanks for the reply. I recognize you from the Rez forums when I used to have one .
So, tried that. I plug it in (device is off now because it ran out of juice apparently), and the light blinks, splashscreen comes up for 10 seconds.
After that, it reboots, and the charge light doesn't come on again, and then goes into its bootloop.
I also tried holding the Vol down for around 3 reboot cycles, both on and off the charger.

Is it a goner?
to me it sounds like there is still hope. as long as you can see the splash screen you still have a chance.
i would put it in a wall charger and just leave it for a bit about 20 min and then try the vol - and power.

That's what I was thinking as well, going from my experience with the Rez anyway.
Alright, I'll just let it sit on the charger for while and hopefully the buzzing doesn't annoy me too much lol.
Still can't get into bootloader .
Tried after about 30 min of being on the charger.
Something weird I noticed, if I press/hold power+vol down while it's on the splash screen, the back/home soft keys will blink 6 times, then the phone shuts off/starts back up again in it's loop (but they won't blink if I was already holding them down before the splash screen came up). Not sure if this is relevant or not, but I figured I would mention it.

Tried it - screen still just goes black, and then repeats the splashscreen bootloop like before.
Should I try contacting HTC and see what they would charge to send it in?

I have this happen to both my max and my kids m8. It was a matter of timing the power and up button combo and then shifting to just vol down the second it rebooted. First time took me twenty minutes to get it right. During which I may have broke a sweat. Don't give up just yet.

So, I should hold Power + Vol UP while on the splash screen, then when the buttons flash, switch to just Vol DOWN? Or am I not doing the correct technique?
So this is what I've tried doing; not sure if it's the correct timing or not:
From a dead battery, plug in and hold power + Vol down, it just goes into bootloop
During the bootloop, held Vol Down during the black screen in between the white HTC splashscreen; still bootloop (tried this at various times in between the splashscreen loops; there's about a 5 sec gap of black screen)
Tried the same above, but with Power + Vol Down
Tried Power + Vol Down during the white splashscreen, the back/home soft keys blink 4 - 6 times, and releasing the power button while keeping vol down held, and then reboots into the bootloop again
Not sure what to do at this point, besides contact HTC, unless you guys have any ideas/proper order to press the buttons?
Edit: plugged it into my computer, and about 3/4 of the way through the HTC Splashscreen, I hear the USB plugged in noise, then immediately the eject noise. For a second I can see "Android Phone" listed under Devices and Printers. Tried running fastboot reboot-bootloader and it didn't catch it. Tried running adb devices during the second it's recognized, but it didn't see anything. Tried in both USB 2.0 and 3.0 ports.
Also tried pressing Vol down during the time its recognized, but either my timing was off, or it didn't work.
Update: Also tried holding the light sensors under a lightbulb and tried the above attempts (read somewhere this has worked for people)... still a no-go.

Still haven't been able to get it after a couple days of trying on and off.
Contacted HTC and I'm going to send it into them.
Since I'm not sure what HBoot is on it currently... if they were to update it to the latest (newest OTA) that's just been released before returning it to me... will I still be able to unlock bootloader/S-Off with Firewater/Weaksauce?
Thanks for the suggestions you guys provided dottat and synisterwolf I appreciate it!
sorry ive been away, work has be busy. If they do update it, there is no way to unlock or s-off ATM. the OTA might be to new for them to care and just flash you back to 4.4.2 sense 5.5

No problem man.
Lame.. hopefully hey don't update it. According to the agreement notice they emailed me with my ticket info and stuff, it says" Please note that all repaired devices will be set to carrier or HTC specifications, and will be factory reset."
Hopefully that means that they'll just reset it back to how it came and not update it.
Otherwise I guess I'll either wait or try and sell it, since the device itself is pretty much mint.
So I got it back today from HTC... and I think they updated it . Can somebody confirm for me?
Bootloader says this:
PVT SHIP S-ON
HBoot-1.57.0000
Radio-1.13.41.0421
OpenDSP-v32.120.274.0909
OS-4.10.605.3
Settings says:
4.4.2
Sense 6.0
4.10.605.3
So there's no way to root, or S-Off, or bootloader unlock right? Neither Rumrunner nor Firewater work? Is an unlock exploit being researched?
Hello everyone, my girlfriend is having an issue where her m8 won't turn on. We looked at it last night and put it on the charger (although we didn't expect it would be dead already) and then left it over night. Woke up this morning and it's still having the same issue. I tried doing both a hard reset and soft reset, just anything to get it out of this weird loop it's in. Everywhere I look for information on hard resetting it says you need to disable fastboot - something a little difficult to do if your phone won't turn on. Are there any other tricks or work arounds that maybe I'm overlooking? I'd prefer to stay away from 3rd party fixes if possible that will void the warranty as I don't want her phone to get rejected if we need to send it out for repair. The closest repair facility is a bit of a distance so I want to see if there is something we can do from home first.
Thanks!
Disabling the "fastboot" option isn't really necessary.
Although I'm not sure what "weird loop" means. If its actually doing a boot loop, and rebooting, then just hold vol down to enter bootloader.
Otherwise, if its just "stuck" on the boot screen, then hold power and vol up to force a reboot (hold for maybe 10 seconds or so); and the moment the screen goes dark, let go of vol down and start holding vol down and don't let go until you see bootloader.

My apologies, my terminology may be incorrect.
The display is not turning on. Holding power + volume up or power + volume down do not get the screen to turn on.
The instructions I looked at all say disable fastbooting before trying to force boot or hard reset. So that was my confusion.
I really appreciate the help.

Any charging LED when charger connected? Any response from computer if you connect the phone?
Leave the phone on charger (wall charger, not connected to a computer) overnight, and try the button combos again (also, try just holding power down, no other buttons; in addition to the button combos you listed). Try this with the charger connected, as well as without.
Some folks have gotten their seemingly dead M8's to revive with apparently random combinations of button pressing (often holding the buttons for a long time, 1 to 2 minutes) charger plugged in, etc.

The only reasons instruction say that, is that the phone either needs to be "real" power off, or a reboot in order for the button combo to go into bootloader (power + vol down) to work. When "fastboot" is selected in Power settings, it actually prevents a real power down (its actually just a sleep state). But if you reboot, it doesn't matter. A reboot is a reboot, it doesn't matter if "fastboot" is enabled. And Power + vol up is one way to force a reboot.
None of this matters, if the phone is not responding (screen not coming on) at all in the first place.

I did leave it on the wall charger last night and was playing with different combinations. I'm going to try plugging it into my computer when I get home. I'm not noticing any LEDs come on however which is what is making me think it's not a screen issue.

I recall reading that someone got a similar issue sorted by hold Volume Up or Volume Down + Power button while holding the phone under a bright light(proximity sensor at the front needs to be directly under light).
There was similar threads/methods on the old HTC One(M7) too that apparently worked. Don't know if it's just coincidence or what Might be worth a shot.
Edit: Volume UP OR Volume down, not both at the same time

Have you tried holding Power and Vol Up button when the phone is pluged in?
Tri taking SD Card and SIM card out and start.
Have you tried another charger?
My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life
Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.
Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks
Your welcome let me know how it goes. Will do my best to help.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.
How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?
To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.
Power + volume down + volume up works for me as reset.

Holy crap the dude is right....just tried that myself on t805, holding all 3 buttons at same time in top left corner power,vol dwn, vol, up forces a simple reset without dwnload mode rubbish.
I was getting a notice on boot that said "Your device is corrupted and cannot be trusted," so I held down the power and volume down buttons to get it to fastboot mode. However, I couldn't get it to be recognized in fastboot on my laptop. At one point I selected "reboot bootloader" and the phone promptly shut off, black screen and completely unresponsive.
From that point on, I can't get it to do anything. I've tried holding power + volume down for 20 seconds and then plugging it in (as noted in another thread) as well as taking it apart and disconnecting the battery to see if that would reset it somehow. No dice.
Any other suggestions before I give up? Thanks very much in advance...

Any other suggestions before I give up? Thanks very much in advance...

my device is for the most part of the time in qualcomm mode, but I managed to have access to the phone 3 days ago, installing apps & stuff, worked perfectly well until I had
the bad idea to try to charge it through the charger instead of charging it through my computer...
how I've done it?
I used the power reboot technic :
1) pressing the power button for 1 minute
2) doing nothing for some seconds
3) pressing the power button again for 1 minute
4) connecting the phone to the charger, the red light flashed
5) the battery icon appeared soon after
6) waiting for complete charge, phone rebooting
it worked once, so I suppose it can work again. fingers crossed.
