[Q] Continuous bootloop so frustrating!!!!

My Nexus 5 is in a Continous bootloop, i literally cant do anything, it tries to boot and gets to the animation screen and then keeps repeating i tried going to recovery to restore a backup but it will go to the bootloader screen for a few seconds before deciding to try and bootup again and failing, sooo annoying. And the thing is I didnt even do anything to it, i was literally using it a few minutes ago to watch a youtube video, then this happened out of nowhere... Anyone have a clue?? This thing is supposed to last me atleast 2 years, no idea how infuriating this is!

since you have rooted i assume you can return to stock configuration!

Help is at hand...literally
This is pretty crazy, I just came on XDA to post about this as it happened to me this morning and I saw this thread so figured you might be having the same problem. My phone went from working fine one second to an unbreakable bootloop the next, I couldn't get into recovery or anything because it would only flash on that screen for a second before rebooting again. In the end I took to frustration, I waited for the phone to reboot and then hit the power button side against my hand (without touching the power button) before it could reboot again and it finished booting into android! I think it must be a hardware problem in which the power button gets stuck down. It seems to have fixed the problem for now at least and I can use my power button properly.
Hope this helps!

[Q] My Nexus 5 rebooted itself 5 times today?

This is the first time this has happened. Basically the screen will just turn black randomly and the Google image pops up for a couple seconds before staying off. The first 3 times it happened I was able to turn it back on by just holding the power button. After that, however, it got stuck in a boot cycle until I plugged it into a charger and tried. So far with the charger plugged in it hasn't turned off yet.
I've attached a screenshot of my battery status. It seems the battery disappeared for a few hours?

Does your battery smell like sulphur?

Sounds like a stuck power button unfortunately. Quite common.
I'd say try flashing stock firmware again with fastboot.... But if it reboots while flashing, you'll be in more trouble.

Let it sit in bootloader mode awhile... See if it reboots or anything. If not, you could try flashing stock firmware. But hopefully it doesn't shutdown mid-install.... That wouldn't be good.

Damn phone stuck in bootloop!

Came home from work yesterday and the Pure XL was dead, said it needed to be charged. Never happened before but I figured whatever and plugged it in and went to sleep. Woke up this morning and powered on the phone and the all white BLU splash screen came up and then the phone went off. Came on again and the all white BLU splash screen came up and went off. Ive tried holding down the power button for over a minute. Tried holding the power button and volume keys to boot into recovery from 10 seconds to 2 minutes, nothing stops it! It just keeps rebooting. This has been my apprehension towards purchasing phones with non removable batteries. The boot recycle happens about every 15 seconds and the phone vibrates everytime it boots up for the past 2 hours. Its getting very annoying and there is no way to make it stop. Any help would be greatly appreciated.

Plug it into your computer (you'll notice that there will be a longer black screen in-between the bootloops) and hold down the power button for at least 10 seconds or more, then release it after the next vibration and the white BLU screen shows up. It might take a couple of tries.
If you manage to boot into at least recovery but can't boot into the system, then try clearing your cache/dalvik cache and try rebooting into system again.
If all of the above doesn't work for you, then your boot.img/system has gone bad, and you'll have to flash the stock images with SP Flash Tool (both of which can be found on other posts on this forum).

follow the instructions on the SP flash tool thread... sounds like what happened to me after bad flash... theres a lot of information in that thread that will set you up...

Thanks for the quick replies guys. The PC trick didnt work at all. I just called BLU and asked for a replacement(havent heard back from them ironically). I put the phone in the basement so I wouldnt have to deal with that incessant buzzing every 15 seconds. Eventually the battery died. Since I had it powered off finally, I plugged it in for about 10 minutes to give it enough of a charge to power on but not stay on to buzz for another 2 hours. This time I powered it on using the master reset button combo and was finally able to wipe the cache and restart the phone. Took a good 4 or 5 minutes to boot after that, but everything has been fine since. Really dont know what initially caused the issue, never happened before. Good thing too, cause BLU told me that they would send me a RMA within the hour and I still havent heard from them. Think this will be my last BLU phone. Thanks for the assist.

My phone Is stocked without root or Twrp. And I find my self having a bootloop once a month for an odd reason. This forces me to take bat out and put it back in or just let it loop til battery dies

My phone is basically out of the box and I'm getting boot loop problems when I first boot. This happens like once a month

This happened to me for first time yesterday. Bought the phone earlier this year and everything worked fine. I restarted the phone because my sound recorder app froze up twice on open and the infinite boot started until the battery died. Tried the {power}{vol up} thing, didn't work to stop it, so I put it in my car and went back to the conference I was attending. Battery was dead when I got out. Contacted BLU by phone and they started a ticket for me, but I figured I'd see if other people were having this issue and learn what they did because I'd rather not be out of a phone for however long it takes for BLU to replace mine. Stumbled on this page. I never rooted my phone. And BLU only sent one wireless update since I've had the phone. I'm trying to get into the menu by connecting to the computer. Worked the first time, I cleared cache, and tried to backup my files, but I'd taken out the SD card in expectation of sending it to BLU. So, Powered off the phone, put the card back in, and now I haven't been able to get the menu back. Still working on it, if there are any suggestions anyone drops on me before Tuesday when I'll likely ship it (or at least hope to because I'll be yelling at them Monday), I'd appreciate it.

I tried to flash the phone, but the bootloop apparently wouldn't allow that. I had 0.0% progress after 3 hours. I then tried to go back into the menu you get from {Power}{Vol UP}: still no go. So, I started to take the phone apart again to get ready for shipping. The battery was still low so it didn't take long for it to die after I unplugged it from the computer. Out of curiosity, I tried to repeat finding the menu like I did earlier that day (conditions were that the phone had no charge when I connected it to the computer, and my SD card was removed.) No go. But, then I hit {Power}{Vol Up}{Vol Down} just to see what happened, and boom. My phone loaded up. No loop... Figured somehow the files had copied and the status bar was wrong. Turned the phone off, put my SD card back in and turned the phone on. Loop reappears ...I waited for the phone to die again, took out the SD, attempted to turn it on and the loop was there. Connected it to the computer and hit all 3 buttons, and the phone loads up. So, now I'm confused. Is there any way that the problem is some crappy connection to the SD?

Galaxy S7 won't turn on but will charge(kinda)

I've had this phone for about 2 months now, and from the beginning, it's had an issue where it would randomly freeze, restart, and get stuck in a boot loop for random amounts of time. Sometimes it would be fine after 2 minutes, sometimes it would need 10. I kept thinking this was a firmware issue - the phone WAS rooted with TWRP installed, but none of my past phones have had this issue and hardly anybody online seems to have had it, either - and just thought that maybe installing a custom ROM would fix it, but never got around to doing so.
3 days ago, my S7 went into a boot loop again, so I just decided to put it down and let it do its thing. After 20 minutes, however, it still wasn't booting, so I booted into TWRP, and cleared the cache and Dalvik cache. Another 20 minutes later, I went into panic mode and started doing Nandroid backups of my stuff. I decided that I had no other choice but to commence with finding a ROM to replace stock. In the meantime, I just plugged it in and let it keep looping, hoping against hope that it would just fix itself like it always did.
About half an hour later, I was ready to install the ROM I'd decided on. I went and picked up my phone, but all that I saw was the screen was black, and the blue notification LED was lit up. I tried holding Vol- + Power to start booting it into TWRP, but nothing happened. The phone didn't vibrate, the screen didn't change, and the LED stayed lit. I tried holding every button combination possible, for even as long as a minute, but the phone refused to respond. I tried plugging it into my computer, but Windows didn't detect anything.
Skip to today, and the phone's battery has long since died(the LED isn't lit up, so I can only assume...), and I just decided to plug the phone in for the hell of it just to see if maybe it would maybe work again. To my astonishment, 2 minutes later, the battery icon came up on the screen, but the charging animation wasn't there. When I held Vol- + Power, the phone actually responded and restarted! Though, it wouldn't boot past the Galaxy S7 splash screen, and when I tried to boot it into TWRP, it went back to being a brick. I let it sit for about 10 minutes, plugged it in, and this time tried to get it into Download Mode, and it worked!
I downloaded the Switzerland version of the G930F firmware, flashed it in Odin, and everything seems to have worked. Odin says it succeeded, but when the phone tried to restart, it got to the splash screen, and after a few minutes, the screen went black again. When I plug it in now, the Galaxy S7 screen will come up, but now I can't seem to get into Download Mode anymore(though, it DOES still seem to respond to me pressing Vol- + Power).
Does anyone have any idea what's going on? I can only seem to find 3 or 4 other threads on various forums about this problem, but none of them have any answers. People just keep saying the usual "Hold Vol- and Power to make the phone restart", but in case I haven't made it clear, THAT ISN'T WORKING.
And before you suggest that I return it to where I bought it for a replacement or refund: I bought this phone on eBay from a seller who said it was in pretty much mint condition. When the phone arrived, there was not a dent or scratch anywhere on the phone, even around the charger port, so I have no reason to believe he was lying. When I asked him about any possible problems with the phone's operational stability the other day, he says he tested it for about 2 weeks, and that he didn't notice anything.

Sounds like a hardware fault, not much else you can do other than flashing stock and factory resetting, which you've done
Considering it had a fault from day 1 it sounds like that fault finally caught up with it
Likely scenario if sent for repair, new motherboard replacement needed

Do you think this is a hardware problem or software problem?

I have a HTC 10 (new old stock) that I have been using for 2 months, on stock Oreo.
Everything was fine until last week when suddenly in the middle of reading an email the screen froze, a few seconds later the screen went black and would not boot up. Nothing at all, not even with a hard reset VOL DOWN + POWER or VOL UP + VOL DOWN + POWER. Tried holding it for A LONG TIME like 5 minutes, no luck. The phone had a hard brick and that's it.
Occasionally, after a few hours, I would try to reset it just for the hack of it. Or connect it to a charger (no charging light) Eventually after about 20 hours, it booted up again after I held all three buttons for a few seconds. Then it worked like nothing has happened.
It kept running for several hours, I charged it up to 100%, ran down to about 80%, then the screen froze again and died. Same thing happened, won't boot up at all. But if I wait another day or so, kept trying, it will boot up again.
I know the HTC 10 is known for it's horrible battery drain issue, and I have experienced that myself with another HTC 10, this is not it. The battery is running fine on this one. This is something else.
After doing this for a few iterations, I was able to figure out a pattern.
When the screen froze and the phone dies, it will not boot up no matter what you do. But for some reason something is still going on as the battery is still being consumed, a day or so later, when the battery is completed depleted down to 0%, and as soon as it hits 0%, whatever causes it to not boot unlocks and allow it to boot again, as long as you have it on the charger, the charging light will come up at that time, and as soon as it gets a little bit of juice, it will boot up again normally. Except when it does boot up, the date is reset to December 31, 1969 7PM.
After testing this for two more iterations, I am reasonably sure this is what's going on. Then I did a factory reset.
Once it's factory reset, I did nothing except turned on WIFI and didn't do any further setup except surf the internet a bit on WIFI, and about 10 hours later, it died again. Now I know, if I leave it alone for 20 hours, then plug it in for a few minutes, it will boot up again.
So here are my questions.
(1) The phone appears to have bricked during the 20 hours that is was totally non-responsive. What is happening that's consuming the battery?
(2) Does this seem like a hardware issue or software issue?
