I've been having a lot of battery issues recently and was told by Verizon to reboot my system. "Android System" was taking up 40%+ of my battery, resulting in my battery life plummeting before half the day even ended.
I rebooted my device several times now, and I just did so again in hopes of renewing my battery life.
Now it won't even turn on.
I reboot it, feel the vibration, then see the SAMSUNG logo. It should move on to a screen that says "optimizing applications, please wait", but instead I am getting VERIZON. it never starts up.
I've done this repeatedly for the past 10 minutes, nonstop, and I have gotten no positive results.
Help please!
What can I do?
Have you tried pulling the battery out, waiting a few seconds then putting it back in and switching back on? If you haven't modified your Note in any way I expect this would do the trick.
Do you have the stock recovery that came with the device or have you flashed a custom recovery? If you have a custom recovery you could try erasing the cache then reboot.
Hopefully someone with more experience will be along shortly
Try flashing your latest carrier branded stock firmware from Samsung updates. Do not flash anything else except Verizon stock

TL;DR: I have flashed the stock 4.2.1 image through fastboot, and yet my n7 wifi still reboots continuously at the google screen with the little unlocked lock.
Background: I have had the device for about 3 months, no real problems with it before this. I was reading yesterday night and i fell asleep, and thus instead of being on my desk all night the device was under a blanket. When i woke up, I opened the cover and found it on the google screen with the lock. It was warm, but not incredibly so. I thought it was weird that it had rebooted and apparently frozen, but i held down the power to turn it off. when i turned it back on, it started the google screen, then went black, then started the google screen again. Seems like there may be some sort of a kernel issue that is keeping it from booting. The next thing i did was to go into recovery (had CWM at this point, and it was rooted as well but that's a moot point if i can't get into the system.) and i did a backup, then wiped data and did a restore from the backup that i had just made. after rebooting, it made it all the way into the system, and seemed ok. I set it down, and a few moments later it turned off and started doing the loopy google screen thing again. Next, I went into recovery and wiped data/factory reset, and tried to boot up. no luck, still looping. Next, i grabbed the 4.0 toolkit from the dev section and tried to flash the stock recovery from that, but it was proving troublesome so i just downloaded the image myself and fastbooted then replaced cwm with the stock recovery, wiped everything, and flashed the 4.2.1 image. that should have worked, from what i understand, but no, still being loopy. I re-wiped and flashed, tried 4.1.2 instead, that didn't work, and i re-did 4.2.1. after flashing 4.2.1 and then leaving it boot looping for a little while, i noticed that it sometimes made it into the boot animation and then the animation froze and it rebooted and looped more. after a few more tries, powering it off, leaving it for a few min, and powering it on again, it booted all the way to the welcome screen to pick a language and then froze. some number of loops later, it made it all the way to picking a wifi network and froze. I have yet to make it past that point. Thinking it may help, i fastbooted CWM onto the device, so i have a more capable recovery now. I am now going to look into pushing a non stock rom to the device to see if that will help at all.
Any ideas on what on earth could have caused this? Was it just that the device was a little warmer than usual for a while?
Any ideas on how i can fix this? Much appreciated!
Lastly, should i consider looking at sending it back to google? I didn't think there was anything wrong with the hardware, but i'm not sure.
Thanks!
Update: After leaving the system repeating it's loopy boot thing for about 45 min, it seems to have finally booted into the system, and has yet to reboot again. I have no idea why this happened in the first case, nor why this finally worked in the end, but so far it seems ok.
More: Ok, so it still seems to be looping a lot. I have no idea why still. I'm having trouble getting it to boot back into the system, so hopefully something helps fix this.
Ok, so a day later it seems to have settled down such that there's very little looping on the google logo screen any more; now it just tends to randomly reboot when in use. this is quite frustrating, but seems more similar to what others have reported to be the case with 4.2.1. oddly, i never had these reboot issues before it decided to fail the first time, so i'm not sure if this is just because ii'm on 4.2.1. I may look at flashing back to 4.1.2 and staying there, i suppose it can't hurt. does anyone else have any ideas as to what could be going on?
Hey all! I'm having a strange issue regarding boot looping that I can't seem to find an answer to on here or anywhere else, I hope you guys can help.
So my T-Mobile Samsung Galaxy S5 (SM-G900T), purchased in May 2014, while perusing Facebook the other day, randomly shut down in the middle of perfectly normal use and started bootlooping. I had never had the problem before. The device had been rooted for months (I forget what method I used) but it was running a stock Lollipop rom. The first thing I did was factory wipe and cache wipe through Android stock recovery. It worked!... for a couple hours. Then the bootloop started again.
I went and sought a new stock rom, believing that somehow mine had been corrupted, and flashed it via Odin. I also flashed TWRP. Clean wipes, new rom, dalvic/etc. wipes, and booted into stock Marshmallow. It worked!... for a couple hours. Then it started bootlooping again. I went into TWRP and tried to wipe just caches and whatnot, but it wouldn't start again. Long battery pulls sometimes allowed the phone to boot, but it started looping again after ~5-10 minutes.
So I installed the Twisted Lollipop but couldn't even get that to boot. I went back and found the earliest available firmware for my device (as I bought mine right after it came out) and flashed it. Wipe wipe flash wipe whatever, and a succesful boot. It was looking good! I was able to install a number of OTA updates. I was at Android 5.1 when I decided to call it a night and hold off on the further OTAs for today. Today I got up and got ready for work, all's well. As I'm getting ready to leave, I allow Google to update some apps, and begin installing Facebook, Spotify, Cap Metro (for my area's public transit system) and maybe something else, I don't remember. Anyway, as the updates are downloading or installing and I'm checking my email, boom, crash, bootloop.
What's going on here? I've never heard of hardware causing boot loops, but could it be that? I dropped my phone (although protected by a Spigen case) earlier this summer and it cracked the screen-- could it have messed with the motherboard in some substantial way? I had noticed it getting hotter and the battery lasting less than usual, but I attributed that to the device's age.
Any help, any advice, any direction you could give would be extremely appreciated. I don't have the capital to replace the phone right now, and I use it all the time. Thanks folks!
Recently bought a new out-of-the box Galaxy S4 I337 from Amazon. Had i known how much trouble it would give me, i would have picked something else. When i first turned the device on, it was almost totally unusable due to lag and random reboots. Software version was 4.4.2. I used Odin to flash a rootable NB1 onto the device. Still had lag and random reboots. Upgraded to lollipop using this guide: https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078 and still have lag and random reboots. Also, the first time i upgraded to lollipop, i installed safestrap not knowing it wouldn't work on lollipop. Obviously, my recovery disappeared. When i figured out what was going on, i did a fresh install of lollipop. I got recovery back, but today when i tried to boot into recovery to wipe the cache, i discovered it had mysteriously stopped working again. If i attempt to boot into recovery, it just skips to the Samsung logo. I didn't install safestrap or any other custom recovery this time.
When i turn the phone on, either it hangs at the AT&T white splash logo and refuses to load at all, or advances to the lock screen. I have disabled animations and every widget i could on the lock screen and yet when i attempt to unlock the phone, it usually freezes. If i repeatedly swipe the phone for thirty seconds or so, it unlocks but it is still frozen and i have to continue swiping to prevent it from locking again. Eventually i'm able to navigate the phone normally, until it randomly reboots or freezes. Sometimes i see an error message that Touchwiz home, Process System, or SystemUI has stopped working or is not responding. This is always accompanied by a freeze. Also, choosing an option in the dialogue that comes up when i press the power button (shut down, reboot, etc) invariably causes the device to soft reboot. Other times a soft reboot happens totally at random, even if i'm not doing anything. Anybody have any idea what's going on or did Amazon just sell me a dud? All of these issues have been happening since before i rooted the device or upgraded it, except for the disappearing recovery mode.
Thanks in advance for your help.
Sounds like a data factory reset is in order. First you need recovery back so I would odin the latest firmware for the phone that can be flashed in odin. If it's still messing up then get Amazon to replace it.
Since you have safe strap though, try booting a TW based rom like Thor ROM or Golden eye ROM. That may fix some things.

Just wanted to bump this to thank you for your reply. Never got the phone to work but i was able to get it back to stock and return it. I got a refurbished S5 instead.
I have a SMG870A that will not stop rebooting no matter what I do. The phone was on PK7 and has ran flawlessly for the past 3 months I've had it. Phone one day reboot and never booted up again, just bootlooped. After wiping cache/wiping data, I've had no luck. I tried reflashing the pk7 stock image from sd card, the image flashes, restarts like normal but reboots half way through the splash screen. So then I tried to Odin the phone back to OF3, no luck either. I get a pass on Odin but when then splash screen comes up, it reboots. I have a brand new battery in it, and I am not sure what else could be causing this. I have very good knowledge on flashing, as I've been doing it since the S3's came out. But this device actually has me stumped. Any help would be much appreciated!
Thanks
Hello. I have A Samsung S7 SM-G930A. I was using smartview to cast to my laptop and it overheated the phone and completely drained the battery. I don’t know if that is the cause of my problem but I’m just mentioning it because my problem started around the time I did that. The phone now overheats several times a day. It freezes for like 10 seconds then starts a boot loop. It could take up to an hour to finally come on again often with my intervention to force restarts. During usage, simple actions like switching data on and off, incoming calls, switching apps or simply responding to an SMS leads to a freeze then boot loop. When plugged in during this state it rather boots into recovery mode. I have the latest version of the patched Odin so before suggesting answers here’s what I’ve already done. I have flashed variations of firmware from the trusted sources (sammobile, updato, etc), I have done NAND erase, I have flashed PIT, I have flashed to G930U and back to G930A, I have done numerous factory resets and cache partition wipes, I have updated all apps (samsung and google apps included). Most of the time flashing only solved the problem for like 2 hours and it was back to the boot loops. Could this be a battery issue? The phone has not fallen or been exposed to the sun for long. It’s always with me indoors. I have tried everything I can think of. I will appreciate your help on concluding if the phone is dead for good. Thank you and sorry for the long question.
