Tab 8.4 boot loops - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

My tab has started to suffer from boot loops, first I tried wiping cache in recovery but that didn't work . I then factory reset the tab in recovery. This stopped the boot loops for a few hours but they returned, I have now flashed a full stock firmware via odin and all seems well though only been half a day.
I was curious to know if any other members had suffered this issue and if so how they fixed it, I have no sd card in.
Thanks in advance.

I have never experienced this with my tab, I've been on CM and I'm currently on complete stock not rooted and still no problems

Could it be a faulty battery? I don't really know tbh
Sent from my LG-D855 using Tapatalk

Thanks for your reply, I'm sure it's not a faulty battery as I had it in download mode (only way to stop it looping) for 2 hours while I waited for firmware download from sammobile . Tbh honest I'm thinking of getting a tab s2 and selling this on ebay, but I don't want to sell an item unless I'm sure I've fixed the issue.
P.s I have no idea why I want a new tab as this one is great but ya gotta spend ya cash somehow.

Even my tab does that and I flashed stock firmware from sammobile but it did not fix my problem. Can anyone help me please?

Okay update time. No boot loops so that's a positive. This tab is running very hot though and when I think about it, it was hot just before the boot loops 1st started. I downloaded cpu-z and with only the cpu app open the cpu load is over 50% and all four cores are bouncing between 1500 and 2 . something ghz.
Any ideas of what could be causing this, it's a fresh firmware flash with about 5 apps installed from the playstore.

Phone keeps resetting randomly

Don't know what happened, my phone has been going strong with a the SuperGalaxy rom 1.7 with no problems. I recently updated to 1.8 and it ran fine for the past two days with no problems. Then after leaving the phone on the charger at work yesterday, the phone kept resetting randomly. I unplugged it, hard reset, flashed a different rom, everything, and it still keep resetting randomly. Not sure what the problem is, any suggestions?
Edit: I'm a dumbass, realized my cpu was under clocked to 800mhz, running smooth at 1400mhz now.
okay, i'm not a dumbass (maybe). Phone keeps resetting on its own randomly still but less frequently after I overclocked.
How is your battery condition? Like how old is it? Do you have and tweaks (kobridge or phakker scripts)
Cpusleep app? And you said it happens on a few ROMs, I would say it maybe a battery or hardware issue. Also, do you check the MD5 sums before you flash the different ROMs?
Sent from my SPH-D710 using XDA
Battery condition is good, I actually have two oem batteries that I use daily and swap them when one dies.
I'm not running any tweaks currently, but when I flashed the roms recently its been through a nandroid backup of my previous working rom. But I'll try a clean install without a backup and see if that works. Thanks

Okay, just did a fresh clean install from recovery. The phone still resets, I've noticed if it's plugged in to a charger though instead of resetting it will just turn off and show me the battery charging screen.
Also, how do you check the MD5 sums? I always thought the phone recovery automatically checks this before it flashes a rom?

Are you using a stock battery charger? Is the charging cable damaged or loose? I had an issue with an after market charger making my phone freeze up before.
Not to my knowladge, but it never hurts to check it. I use md5sum app.

Okay, I flashed a totally different ROM and it seemed to have solved the problem for now. Most likely it was a ROM issue, which is kind of weird since it was using the same rom before without any issues, even when I did a recovery of it. Oh well, maybe it was the right combination of apps and crap. But so far right now, everything is good. Thanks for the help g_ding84!
What were you using to under/overclock? Setcpu specifically has been known to cause the exact issue you were having, namely random reboots, however I would not be shocked to find other overclocking utilities that could cause the same problem. Regardless I'd be willing to bet that whatever you were were using to adjust the clock speeds was the source of the issue as opposed to the ROM.

You may be right on the money with that. It could be causing script confliction. Between the ROM and the CPU app. But I do know that cpu app scripts will override the ROMs cpu scripts, but not all the time.

Does it reboot in download mode? If not..I would odin to stock and go from there see if that fixes things.
Update: still resetting. :crying:
Today its been resetting probably about once every few minutes to ten minutes. It's stupid, like the battery will say 60% and when it reboots on its own, the battery will be at like 10%. No idea what the issue may be, but I might try to see if it will reboot in download mode as some of you suggest and maybe try to flash a stock rom. It seems that when it does go in reboot crackhead mode it will do it even in recovery.
The power button will not be as functional during the crackhead reboot mode as well. I'll press it and nothing will happen, but the screen will come on itself (not sure if this is a delay or just the screen coming on by itself lol).
I'm not too worried about exchanging it as of now, since I'm in the market for a new phone, but would like to fix this issue so I can sell the phone; if not I'll just do the trade in thing with Sprint (even though I won't get as much).

Trade in is roughly $80 bucks (i'm looking to do that with mine this weekend hopefully for the S3) Sorry your having issues.. Mine has done it once ina great while.. but nothing crazy. Good luck on new phone! (I'm a craigslist junky so i'll shop on there for temp replacements lol) Got my Touch for $50 which was an upgrade from my OG Epic.

Having an issue with random reboots

My new galaxy note 2 randomly restarts. On 2 occasions that I caught it was
1 I was on the phone with my father 20 seconds in
2nd I let go of my phone 1 inch from a Reem of paper to place it down ( im unavle to reproduce that one )
But many times ill pull my phone from my pocket or my lap and see its in the middle of a reboot
Related or unrelated I've been getting these gaps and battery drops not during heavy use possibly around resets or not
Haven't rooted only installed a few games facebook and I heart radio. Email is set to only download when I hit refresh and updates are manual

I'm having the same problem. My note 2 just reboot twice in 10 minutes.
Same problem here. A random reboot every second day or so.
I can confirm this also. (Sprint version)
Me also facing this problem. Same happening atleast twice a day... any solution to it??

Guys, just an idea. Stating "this happens to me" without mentioning the firmware/build number is kinda pointless. I'm on stock ALJ3 and I'm not facing this issue. If everyone lists theirs then maybe we can narrow down the issue if it's related to firmware.

Just got my GN2 yesterday and it's randomly rebooted like 6 times at least.
Maybe it something with Sprint version guys. If not try to full wipe and flash stock rom by ODIN only.

I ended up taking the phone back to att and had it exchanged. Haven't had the problem and no battery drops
Heeeeeeeeeeelp!!

[Q]

When downloading a rom it says nand and full wipe. What does it mean when it says nand? I currently have a samsung moment that a have owned for 2 1/2 years and i have rooted my phone and changed the rom plenty of times. I will b upgrading to a samsung galaxy s3 in 7 days.
Nand = nandroid = full system backup. Always a good idea.

Help... Bootloop? But not a bootloop? Confusion.

Rooted my i317 2 days ago with the "no triangle counter" method. All was good, got TWRP installed, nandroided stock and did my thing. Been rooting phones for many years and have yet to brick anything *knocks on virtual wood*. Installed paranoid android, and all was awesome. Decided to give another rom a try... Cant remember which, but im not thinking thats the issue.
Wiped, flashed, no errors, rom booted normally, but as i unlock the device i get three force close errors. Then reboot. Over and over. Restored three different backups and all three do the same thing. Never run into this one before. Admittedly i am worried. Not a rich man and bought this phone outright...
I am hoping flashing in odin the original root tar file will correct the issue. But honestly wanted to do some reading and post this first. Any help would be greatly appreciated.
Sent from my SAMSUNG-SGH-I957 using Tapatalk
Did you try flashing a touch wiz kernel before going back to a nandroid? If not try that and if so try a factory reset and then a good old reboot!
I assume you tried a cm10.1 rom?
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2
Same thing happened to me and I did just use odin to push that tar file through, rerooted, and flashed in my rom. That to me seems to be the fix for the bootloop imo. But someone with more knowledge could correct me if im wrong. Probably didnt help you any but just thought I would share my experience and fix when I was in the same position.
Sent from my SGH-I317 using xda premium
Both of you are good people. Alleviated is a drastic understatement. Was afraid it was a bad internal storage (bad hard drive) and was an issue limitec to my device. Others have done it, it can be fixed.
Cheers, gonna odin reflash now. If not will figure it out.

Help full group over here, Appreciated greatly. Ive messed up a couple devices pretty good in my day, but never beyond repair. Always credited to people round these forums.
The factory reset didnt seem to help. But if system apps are missing... Reflashed the original tar file, and am just sitting here with a lump in my throat watching the Samsung logo hang...
Anyone got a link for the original rogers firmware?

What I did when it was stuck at the Samsung logo was I took out the battery> held down volume up, center home, and power to go into the system and did a factory wipe> then it pulled through nack to stock. Give it a try and keep me posted.
Sent from my SGH-I317 using xda premium
I tried the factory wipe through the cwm recovery included, didnt work. Was still stuck on samsung logo. Reflashed with odin a second time which allowed a successful boot and recovery of my paranoid android backup. Im good to go... Gonna do some more reading though. Im missing something important with this phone. Moving from 4.1 to 4.2 roms or vice versa seems to be... Weird.
Anyways all good. Thanks.

Anyone else just have this pop up?

Did anyone else just have a message from T-Mobile pop on the screen about something to with an update?
Just curious because I just did twice, but each time it stated something about me running an unofficial version of android.
After several restarts it popped up again except this time I was able to grab a screen shot of it. I hope this is really it.

Nothing for T-Mobile T999 in my area yet. Make sure you guys mention your device model, carrier, and current build too please. These will all make a difference.
There has been no kernel source released yet though and from what I've seen recently they've been releasing that before or at the same time as the updates. Doesn't mean anything for sure but figured it'd be worth mentioning.

Nothing for me either, says its up to date for my T999, just flashed to NC2 to check :/
Sent from my SGH-M919 using Tapatalk
Oh, and if you get the update and want to pull it so you can share it here, this is what you do.
Let the update fully download, but when ready choose postpone. Next flash twrp via Odin, then reboot into recovery. Use the built in file manager to copy the update.zip to your sdcard. I think it will be in /data/fota or maybe in /cache. If not just look around for the fota folder.
Or if you choose, flash the supersu zip after booting recovery, then reboot, install a root browser and copy it that way.

I don't recall where I seen that doc, I could be completely thinking of something else not too sure.
If you've flashed back to purely stock you can force it to check. Go to settings, about device, software update. What is your current firmware build? Were you using a custom rom when you got that?
Sent from my SGH-T999 using Tapatalk
No pop-up for me... T-Mobile user here..
I flashed to stock, but I'm not exactly sure the Odin files I used were up to date and couldn't check due to needing to flash cwm in order to get it to boot fully.
Had to clear dalvik for it to boot after 1hr of waiting.

Would be good if we can know what rom he was using(or still using)when that happend...
