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

I have a rooted stock phone that stopped working for no apparent reason (no new ROM flashed, no configuration change). It starts, shows the Samsung logo, and immediately reboots. I tried to put it in download mode, when i hold the 3 keys I see the download logo showing up, but it reboots after a few seconds anyway. after a while it will start looping through the battery charge screen (which shows the battery as empty). I tried 2 different batteries with no change. Any idea how to get something working again?
That almost sounds like some sort of power issue. Have you left it sit turned off until the battery was full?
Yes, I left it overnight and it just keeps flashing the battery screen and then resets. I also have an external charger and used it to charge the battery, so it's not an issue with the battery actually being empty.
Have you been able to get the phone into download mode previously?
Have you have dealt with a boot loop and performed an Odin recovery previously? If not, remember it can take a few tries to get download mode to pop up.
If you can't get Odin to go, you might try flashing with Kies.
I am wondering if your phone met with some kind of disaster when you weren't around (trauma or liquid).

This sounds almost exactly like the problem I had with my Sidekick. In my case, it turned out to be a bad battery and a loose ribbon cable on the motherboard. I'd check those two things.
This happened to me as well, and the three-button method to get into download mode wasn't working. For some odd reason, for me to get into download mode all I have to do is hold down the power button + track pad, and it goes right into download mode... Maybe slightly different model?
Try that - power button + trackpad
Bootloops.
Not a guaranteed fix by any means but for troubleshooting purposes you may want to consider making a USB JIG. It will most definitely help you figure out just how serious the problem is and if it IS software related with a way to get it working again you will need the JIG anyway so its worth a shot. If nothing else you learn a new skill and you're the proud owner of an incredibly useful tool that you can say you made yourself. good luck!
I know this post is kind of old, but it just happened to me last week (same circumstance, a rooted phone, but stock). I ended up just pulling the battery out and pressing the power button a couple times to hopefully drian it and letting it sit for 15 minutes, and then I put the battery back in and it worked again. I now have another rom flashed on it, I hate stock.
I know this forum is ancient, but I'm working on an E-Bay phone with this exact issue. I found the following thread the most useful and informative on the problem:
http://forum.xda-developers.com/showthread.php?t=1996709
Hopefully this helps other.
what i did was hold the power volume and button between the menu n back with the left hand YES HOLD IT UNTILL THE PIT IS UPLOADED. then u can let go then slide in the vattery with the right.while checking off the flash bootloarders on the heimdall with it fixing my phone XD
I had this happen, I dissassembled the phone, and used an alcohol pad to clean the power button area, and manipulated the button a lot, let it dry, reassembled...it still bootlooped.
BELOW IS RISKY BUT WORKED FOR ME
So while the back cover was off (exposing the cicuit board but everything still connected) I inserted the battery and watched it boot loop...during this, I used a flathead screw driver to "short" the power button pins...this let it boot fully, and it has been fine since.
i smacked the phones power button a few times and it worked
If this thread is more appropriate in another section, mods please move.
I'm by no means a lost newbie, having run a rooted & rom'd Epic 4G since release date and flashed it many times, modded, customized, etc, etc.
However, this dang Photon is giving me hell..
Just got the phone yesterday, unlocked the Bootloader, rooted, etc, etc. Tried updating the phone before realizing it doesn't work without stock recovery, so restored the phone back to stock'ish using some TWRP stock dumps someone posted. Flashed stock recovery back, booted, got the phone to download and apply the update, flashed TWRP back, rooted, booted, everything is good. Ok, finally I can get to restoring some data using Titanium. Restored a few things, it was getting late, and I knew it would take a while to restore my SMS/MMS messages so I kicked that off before going to bed. Phone was plugged into the charger all night. Woke up this morning and the phone was only at 50% and the SMS/MMS restore in Titanium seemed to be hung. Phone was still fully responsive, accessed the market, checked emailed, then I shut the phone down via the power menu in order to un-hang that Titanium restore...phone turns off, then shows the unlocked bootloader screen, then shows a backlit black screen and will do nothing else. Won't turn off, no combination of vol up/down and power will get into recover or fastboot. Phone has just been sitting there for about an hour now with a blank/black (but backlit so it is powered on) screen.
Any thoughts or suggestions or am I screwed at this point?
I don't know why I'm having such issues with even mildly modding this phone...
Ok, after about an hour and a half of just sitting there, the phone showed to be fully shut down. Was able to boot in to TWRP, so I then exited and rebooted and it booted all the way into the OS.
Not sure what happened or why, but I hope I'm good now.

When you powered off the device was it still on thee charger? When I power off and mine is on the charger it does the same thing. I just unplug the powr and then use poer button and vol dwn at same time to pwr off. Just threw that out there just in case it happened again.

It was plugged in when I did, but a few moments later after it did what it did I unplugged it, still was unresponsive to any power key / vol key combo, tossed it in my pocket & left for work. Tried it a few more times on the way to work, still nothing, tried it again when I go to work, still nothing, then grabbed the phone to check on it about another 30 mins later and it had fully turned off on it's on.
Who knows...been fine since.
Hello.
I have searched the forums about my issue, and although there are a lot of threads about phones rebooting, there was none about such exact problem as I am experiencing. I apologize if I missed a thread which tackled this problem.
Symptoms:
1. my galaxy S 4G reboots about every 3 seconds: it only gets to the very first "Samsung Galaxy S 4G T-mobile" logo, and reboot
2. it is possible to access boot menu (volume up+down), but only for a split second, and phone reboots again
3. rebooting starts as soon as in put battery in, no need to even press the power button
All that started by itself yesterday. I thought it was a mechanical fault with power switch, I opened the phone, unscrewed covers, cleaned everything, but found no mechanical issue. I switched batteries, tried starting the phone of plugged-in charger, on usb cable, took out sd card, sim card, put a different sim card in... and nothing helped.
Phone runs on Gingerbread 2.3, stock by T-mobile, never had any other roms on it. Device is rooted.
If anyone has an idea how to approach this issue, please let me know. Or reply with a link to somewhere I can read more. I was not able to find much on this...
Thank you!

The phone sometimes does a reboot loop if u take the battery out of the phone without turning the power off. Just keep trying to turn it on, and eventually it would reboot properly. Take the battery out of the phone for a few minutes, put it back and try to turn it on again. Do this a few times to see if it boot back properly.

Thank you for a prompt reply!
I did take out battery for a long time, well over one hour, and took out sim card and sd card as well. Unfortunately reboot loop started immediately when I placed battery back in the phone. That's what made me think it was a mechanical issue with power button.
I will try keeping battery out a few times again today.
One other thing: the phone had been in hot and humid environment for about 30 minutes before this happened. Not the first time for this phone to experience high humidity, though. However, I did not find any moisture inside the unit.

I had this happened to my phone. Just wait it out and keep trying to reboot, it will come around. Take the battery out and put it back on. Keep on repeating this step.
Also, when the phone is on, try to hold the volume - + and power button at the same time to see if u can get into boot mode.
Also u can use hair blow dryer to blow dry area around the power button.

Or, batt is dead...
You have a stuck power button. Take apart the phone and clean the power bottom with compressed air. Then rapidly push the button in and out for a while.
Resolution:
I took the phone apart, and checked the power button (which had been my first guess), and was seemingly all right.
The battery was also not the issue, as I tried 3 different batteries.
Having no other choice, I put the battery back in, and let the phone happily reboot at its own leisure. After over 20 reboots, the system came on. Then a few minutes later the device rebooted again, and the loop started all over. After a while it booted up again. This time I did not wait for the device to reboot by itself, and I switched the phone off with power button, and then turned back on, and it booted normally. Repeated this once more - normal boot again. One more power off, and I entered the boot menu and did factory reset. Once the stock reinstalled, everything would work perfectly - no more issues with boot loop.
So it seems to me as a software problem more than anything else.
Side note: for the last several weeks the phone displayed strange behavior, that is the screen would light up for no reason by itself, and quickly go off. Sometimes it happened once every few minutes, sometimes it happened several times a minute. Did it have anything to do with the boot loop? No idea. But it strengthens my hunch about a software issue, as that behavior also went away after factory reset.
Sorry for the lengthy post, but since I have not found a similar case anywhere in the forums, I though someone might find this interesting. I do not deal with phones except as a user, but some of you guys do it maybe professionally, so maybe this will be a curious puzzle for you to solve.

Hardware not software. You had a stuck power button. By forcing the reboot with the power button you unstuck it. If you don't believe it research Occam's razor. Glad you got it fixed(unstuck) though.:victory:
EDIT: Here are some other people who have had the same issue on samsung phones.

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
Sent from my PURE XL using XDA-Developers mobile app
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?
I purchased my Google Pixel (first generation, regular (ie: not XL)) about a year and a half. It's been rooted for most of that time and I recently updated to Pie. When I woke up this morning I found that the phone had restarted on it's own. After a few minutes I noticed that it was running slowly and, eventually, to the point of non-responsive. I forced the phone off (held the power button until it turned off) and turned it back on. It seemed to load okay, but a few minutes later the phone was off again (which it did on it's own) and I cannot turn it back on. Holding the power button doesn't do anything and plugging it into be charged doesn't show any indications that the phone is charging. I haven't installed anything in at least a week and until this morning I didn't notice any problems with the phone. Any thoughts as to how to get the phone back on and what the problem might be?

See if you still can get your phone into download, fastboot or recovery mode. Here you can see the button combos: https://m.youtube.com/watch?v=YFaq4g-oa2Q
If you can get to recovery mode, click on wipe cache and reboot. If your phone still is stuck afterwards, go to recovery again. There is an option to wipe and reset the phone. Note that your data will be lost!!! Do it at your own risk. But a reset often is the last working choice when your phone behaves strangely.
If you get none of the three mentioned modes to work, I think your Pixel has a hardware fault.
Hope this helps.
check the charging port first....whether it is charging or not......try to connect to PC
i guess the phone is not charging
So the bottom line is this is still somewhat ongoing, though I’ve confirmed the phone is definitely bricked. I brought it into UBreakIFix and after taking it apart (noting that the device seemed physically in great shape) that there wasn’t anything obviously wrong with any of the particular hardware (they mentioned that replacing the motherboard would likely do it, but it would be about as expensive and effective as buying a new phone anyway...).
I ended up writing back to Google and am in back and forth talks with them now. I’m not sure what they can or will do, but my final answer will have to be getting a new phone one way or the other.
