I've searched far and wide, but nothing seems to resolve my issue.
The case:
I have 2 Galaxy Tab S(T800).
One, the oldest, has always run a stock rom + Root
One, I have on LOS 7.1.2.
The oldes one rebooted spontaniously. After searching, i thought it was the battery. On the web people say it often happens with this device. So cracked up de back and checked everything. Thing were looking fine (similar to the working one). Also: in download mode or recovery, it doesn't restarts.
So it has to be software, right? RIGHT ??
I've wiped everything. Factory, Data, Cache. No luck.
Installed the stock rom; no luck. And TWRP then LOS; no luck.
Here is where i loose my mind: Odin gives a pass. The Tab starts perfectly, but upon booting, it quits. On 4.4.2, 5.0.1, 6.0.1. The furthest i've come was the startscreen of LOS, but upon Wifi settings, it reboots again.
Tried to re-partition with the .pit file : no succes either.
HELP wanted. Maybe I can do something with my other, still working tablet.
A free beer for my saviour!

It looks like a failure in the EMMC .. they were defective in these plates (Toshiba brand) mine has that problem and every 3 days they start restarting and I have to reinstall ..

Here's the story. I purchased a factory refurb'd Tab Pro 10.1 (SM-T520NZKAXAR) on Woot a few weeks back. I live in Canada, but it is a USA tablet, if that matters. It came with a 90-day Samsung warranty. As soon as I got it, I started looking at custom ROMs. I have experience with custom ROMs on my HTC One m8 (and old m7), but not with any Samsung devices. I wish I had kept it stock for a few weeks first to check it out, but here we are.
I created a nandroid backup of the stock firmware, however I quickly deleted it during a wipe when flashing my first custom ROM, which was GraveD's v3.0. It seemed to go OK, but then it would start to freeze up and reboot on it's own. This seemed to happen mostly under load, and especially when trying to install apps from the Play store. I tried going back to the stock kernel, thinking that could be the problem. It stopped the crashing, but then wifi wouldn't work. So I could choose between having a tablet that crashes all the time, and has difficulty installing apps, or one without wifi. Both were basically useless.
I tried installing another custom ROM, GigaWatts Pro. Again, flashing seemed to go well, and the ROM also seemed to work very nicely for a couple of days. No random reboots, and wifi worked great. I spent a few days downloading all of my apps and getting things set up the way I like, when yesterday something went wrong. Perhaps the tablet lost its root (is that possible?). All of a sudden, apps are crashing all over the place (Unfortunately, [insert app name] has stopped). Titanium backup hangs at "Asking for root...". Installing apps is also difficult again. The tab doesn't reboot on it's own, but Play Services crashes constantly. Whenever I try to get into developer options, the Settings app crashes. I'm not even 100% sure USB debugging is enabled right now, although I'm still able to flash using ODIN.
I tried doing a factory reset and re-installing GigaWatts. Same problems. Tried making sure the root was OK. Same problems. I've tried using twrp 2.8.0.0 as well as 2.7.1.0 with no luck.
Right now, I've downloaded the stock firmware for Canada T520UEUANI1 4.4.2 (although the tab was bought from a USA site). I assume this also installs it's own Kernel. It shows Kernel version:
3.4.39-2776001

I'm experiencing the same problems. Google Play Newsstand crashes every 10 minutes or so. Settings is almost useless. Installing apps is problematic.
Can anybody tell me if there's something I'm missing? Anything left to try? Does it sound like a hardware/ROM/kernel problem? If it's hardware, can I still utilize the Samsung warranty after trying to flash custom ROMs? I'm going to try to download another Cellular South stock ROM, but it seems like the problems are persisting regardless of which ROM i have installed, so I think it's something else (kernel or hardware-related).
Any help is GREATLY appreciated. My new tablet is basically useless, and I've run out of ideas.
Try this latest firmware since you mentioned your tablet is the XAR model the firmware should be cellular south (wifi)
http://www.sammobile.com/firmwares/download/39630/T520UEUANK1_T520XARANK1_XAR.zip/
If that doesn't help then it could just be a bad tablet .
(btw when you flashed a custom rom you probably tripped the hardware knox flag and voided any warranty it had, I guess you could play dumb if they ask and say it came like that since it was refurbished, and hope they still repair/replace it)
I just tried the USA cellular south firmware. Still experiencing the exact same issues. I'm completely out of ideas. Does anyone else have any ideas? Otherwise I'm going to have to try warranty service and hope for the best. Is there anything I can do to restore the Knox flag before I send it in?
Also, in download mode the tab is recognizing the system as custom. Is this normal after flashing a stock image?
So do a factory reset in recovery, and clear the cache also. Then load the cellular South file thru Odin. Then factory reset again. See if this clears your problems.

I've tried the Cellular South firmware to no avail. I'll be trying to warranty the tablet now. Fingers crossed!
Hello,
I had on my Note 2 t0ltecan Dn3V5 and it started to restart ever so often and my youtube app dissapeared and woudnt work. So I tried to wipe the data and it didnt work, from many TWRP versions and Philz recovery. Then i used Odin to install a stock rom, which then finally everything worked and I then tried to restore my Dn3.
Everything worked except my Action Memo which stopped working so I did the procedure again. Samething, so I tried installing Dn3V5 rom instead of restore. It didnt work because it kept saying bad zip, I tried TWRP 2.8+, 2.7.1, 2.6.3, 2.6.1, 2.5 and Philz. Only 2.5 worked but it woudnt boot after the graphic logo. Then i tried again and the same thing. So i restored again and this time it either doesnt boot after graphic logo or I get IMS Framework problem.
What should I do, restore Stock or DN4?? What could my problem be?
UPDATE:
I used odin again to install stock kernel again, this si the farthest I have got with it booting and not restarting. It is still doing that, sometimes more than others, but I have disabled 5 apps, one google play services and the other google chrome. So far so good, nothing has happened but I will have to experiment more.
I have been formating it many times and closing and opening it by taking out battery, will that affect my phone?
UPDATE 2:
I found the problem, I used my bros Note 2 battery and everything ran fine. My original battery died so I had bought a second hand battery. The whole time (for 2 months) it was causing me problems but I did not realize. After ripping the sticker off the battery I figured out it says 2000mAh on the inside XD.
Hi All,
Having some issues with my Galaxy Note 10.1 which I've had for quite a while now. It's rooted but with Android 5.0 stock rom and a custom kernel.
Just now (like 20mins ago) I tried to enable Adblock plus app, the app said it can't automatically change the settings - even though SuperSU was installed and had no issues with it previously. So like all things thought I'd give it a reboot that ought to clear it out. That didn't work, so tried clearing cache (Dalvik/ART/Cache), Still no joy.
I'm a s/w engineer, but not and android/bootloader expert, so I've tried to grab the dmesg and boot logs which I've attached, I've got some stuff on the internal SD (app data) which I'd like to keep, hence I'm not going for the full wipe.
Please take a look at the logs and see if you can determine how to fix this issue, my initial thoughts were there are some issues with the flash storage (bad sectors/partition table?), if I could grab the image and dd the image again I'd be OK - but I don't know much about about android boot loader/kernel etc so can't say.
Ok it has been fixed by wiping data - but I've lost my data and installed apps!
Is there anyway to find out which file/app is causing the boot loop so I can restore data, delete the offending file?
Well, I shall give a bump to this topic, with a little more info. Though probably not really useful.
First I had stock 5.1.1 deodex pre root etc ROM that, after I tried to insert a nano sim card (mine is a 601 3G model) that got stuck, it entered on a bootloop, I had to open it, take the sim card out, and it was still on a boot loop. Tried to install another image, still bootloop, tried to reinstall the original one I had, still bootloop, wiped data, worked fine.
Then almost 2 weeks later, everything worked fine, went to watch a video, the sound was mute, tried to turn it on but everything looked fine, decided to restart because it would probably fix the problem. Got a bootloop. Wiped the data, everything was fine again.
Now, a little more than 2 weeks later, seems like the wifi is not working, thought all my other devices are, guess it's the same problem, decided to restart it, and bootloop again. I'm currently trying to update my TWRP, and gonna try a different ROM, and wait to see if something like that happens, until then, I wonder what could be happening... I remembered an Asus Device that I had that had different firmware versions for 4.4 and 4.1, so if I tried to flash a 4.4 on a 4.1 firmware it wouldn't work, and for downgrade, the same problem happened, and wondered if Samsung has some difference between versions 4 and 5.
ssj4maiko Let me know if you find a more stable rom - I went back to pretty much stock, but with root as I wanted to use all the Samsung apps, but this constant random bootloops are annoying!
I had the latest 6.0.1 samsung rom (CPK2) which was giving me problems with freezing. So I am trying to upgrade to an 7.x.x rom, either RR, AIPC, or Lineage. But none of these roms allow the T800 boot to get beyond the initial splash logo screen. I am using latest TWRP, 3.1.1 to wipe and install rom. I am not getting any install errors. Boot loader is confirmed as CPK2.
FYI, I am able to get back to the samsung rom by reflashing it with Odin.
Update 1: In the final attempt of upgrading I installed the official 6.0.1 fw which boots fine unlike the aforementioned alternatives (very strange). However, lock ups and now screen blanking more frequent. This time wiped everything including storage. It looks more like a hardware issue but I wonder if this could be malware even after wiping everything. I will have to take this in for repair but have little hope of solving this problem.

My wife has the US Cellular 10.5 variant (T807R4). It was freezing so frequently it had become almost unusable for anything but watching videos. Rooting and disabling most of the Samsung apps did not fix the problem. I wiped the system with TWRP only to discover that none of the custom ROMs would work on this model. I downloaded and flashed the stock Samsung MM firmware (and it sat on the opening splash screen for at least 15 minutes before it finally booted up) and for the hour I used it after setting it up, I had no problems. I had previously cleared the cache with Titanium Backup and that also seemed to be a temporary fix. My conclusion is that something is happening when the cache fills up that causes the freezes but I'll need more data to say that for sure.
Just an update: I was going to have the hardware looked at so I wiped everything including the storage. But when I took it to the shop and was asked to demonstrate the freezing the tablet wouldn't. So I took it back and it was running OK until a couple weeks later when the same problems reared there heads.
Somehow I managed to get a 7.1.2 installed and the T800 is running great...so far. I'll post back if the freezing starts again.

Please explain the steps to install 7.1.2 (and which ROM you used) and update on the freezing issue. Most of the freezing issues I have read about seem to be on LTE variants (SM-T807x) so I was about to buy a wifi only (T800) tablet, thinking that would be a solution to the problem. If that's not the case, then I shouldn't waste my money.
The instructions for installing a non-stock ROM are on the dev's host page in Tab s forums. I first tried Resurrection Remix and now am on LineageOS. It was only after I wiped the internal storage area that I was able to get past the 7.x.x boot screens.
I found the stock rom 6.0.1 freezing issue persistent. I believe the problems started for me with XAR H4 and really picked up with K2 (roms supplied by sammobile). The tablet would frequently just freeze while working in an app: the screen and hardware buttons would not respond at all. Never had that problem with Android 5. The only thing I was able to do to unfreeze it was to reboot into download mode then restart the OS from there. I sometimes found that if I left it frozen overnight it would unfreeze itself by morning.
Hello, just installed lineageos 17 on my galaxy tab s3 and everything seems ok except for one thing. When i open chrome and is about to write or search something the app just crashes, when i pick a saved bookmark everything works fine. Tested with firefox and no problems there just with chrome. Has anyone got any idea what could cause this? Rgs from Sweden
Continues, back to stock
I have a t820 and thought i should try lineage os 17.1. Said and done, flashed the files tablet booted no problems. After a couple of days i thought i liked to go back to stock. Downloaded the latest official fw and started flashing via odin but here is where the problem starts. Odin does not finish the flashing, i have tried many different files and version but same problem. So i thought i will flash lineage again but now the tablet gets to the boot screen but no further. Does anybody have any idea how i shall proceed? Many thanks in advance!
Continues
I managed to install lineageos again but would really like to go back to stock, i have downloaded stock rom from 3 different locations but odin wont flash the whole process, still no fault messages in odin. Does anybody have any idea what could cause this?
Solved
A reinstalled computer and another cable solved the problem!
