[Q] SM-T210R Problems after update - Galaxy Tab 3 Q&A, Help & Troubleshooting

First this is the kids tablet and I don't spend tons of time on the Samsung side as I am mostly hanging in the HTC parts of XDA. I've spent a lot of time in this forum this week reading up and trying to find a solution but I am getting nowhere.
I have downloaded Odin v 3.09 and have been trying to load the firmware update for the WiFi only version and even though it seems to complete fine with no errors when it boots it seems that most everything generates a force close (settings, start wizard, etc.), or what appears to be system reset (not a full reboot but just the OS resets).
I have redownloaded the update a couple times thinking that perhaps I got a bad download or something but that hasn't made a difference.
I have tried downloading the previous firmware a couple times and loading that but I can't seem to get that to boot as it sticks on boot screen.
I just don't know what to do with this at this point and really need some help from the community to get this functional again (my kids are driving me nuts!!!)
Thanks!

Did you do a factory reset before upgrading. The jump from 4.1.2 to 4.4.2 included a lot of changes. If you didn't, try that; then report back.
Our 4.1.2 version roms use the /data/media directory as the "internal sdcard".
4.2+ versions of Android use the /data/media/0 directory due to support for multiple users.
If you switch to a different Android version, you need to be aware of this difference.
I recommend wiping "internal sdcard" also before switching from 4.1.2 to 4.4.2.

Thank you for the reply. At some point in the process I did try that but didn't initially before I started. I have tried that again today and then loaded again and still get the force closes, and such. Tablet is really unusable at this point.
Thanks,

What the What?!

Moderators, please forgive me in not in the right place...
Came home from a glorious week of camping and decided to check out some 4.4.4 ROM's on my phone...
Already running older version of C-ROM, so backed up and flashed the KK 4.4.4 version. That's where it the wheels came off my bus..
Phone booted so damn slow, then there were hundred's of FC's, rendering the phone unuseable. Rebooted, cleared Dalvik and Cache but same difference. The phone died, the battery would NOT charge! No matter what! Try as I may...NO GO!!! For hours! Feared it was that issue wherein the S3 motherboard dies and the phone has to be replaced by Samsung. Kept trying...finally get the phone to boot into TWRP. Whew!!! Still the phone kept complaining that the battery was dead. WTF?!
Restored the back up I had made...accidentally grabbed another backup from december of last year (Cyanogenmod), so had to recover my C-ROM back instead...RESTORE FAILS! Tried a few times but still failed. Tried to re-flash the latest C-ROM, but STILL fails...everything I'm trying fails.
I read the output and see an error, "Unable to wipe /system" ...found a thread where a user, using TWRP, had the same error with their ROM they were trying to flash. Eventually, the fix was to delete the make_4fs (or whatever it's called) from /sbin directory. Did so and was able to flash my Cyanogen, but could not restore my C-ROM backup. That STILL fails, however, no error in the live output while it's restoring. Just ends up Failing at the end of the restore process. The live logs indicate that it's using the 2fs (or whatever it's called), which was successful in flashing my Cyanogen ROM...why will it not restore my C-ROM back? :crying:
Any help would be greatly appreciated.

Have you tried using ODIN to restore back to stock? If you can get the phone up and running, you may be able to restore from your old backups.

Thanks bud.
Oh, I got the phone up and running on the Cyanogen dated dec/2013.
ODIN? Never thought of it. Been such a long time. I do need to get stock on here so I can all the latest official radios etc, then put custom ROMs.
Been such a loooooong time since used ODIN though. Shouldn't be hard to get back on the horse.
Thanks for the suggestion!!!
any idea why this happened? anyone?
as an fyi, I tried to put the lastest SlimROM on but same difference. (i'm really pressed for time always. so I decided this is the quickest thing to try). seems the only thing that will flash is my Cyanogen from December. Strange...
Will have to give ODIN a try if I can ever get the time some day..
Odin shouldn't be a much longer process. Start flash, walk away. When you return 10 minutes to a few hours later, it'll be sitting there waiting for you, all nice and stock!
Anyway, one thing I dont recall seeing you tried is a factory reset. Chances are, that's what caused all your FC. Roms will always take a while on first boot. But all those FC were likely due to incompatible data. Then you may have encountered more data corruption as the system worked overtime trying to resolve all those conflicts.
Its purely a theory, but there's a good chance you will never be able to find exactly what caused all of your issues. Dont lose sleep over it is my best advice! A couple of tips though....
Never wipe/format system! Had you been able to successfully do so, and then nothing would still flash, there would no longer be an o/s to boot into! All roms will format your system partition as the first step in the flash, so there's just no need to do this manually. Most flash failures occur before the flash actually starts, meaning if there's a problem, most times you'll still be able to reboot normally.
Update your firmware. If its been a while since taking an ota or updating via Odin, you're probably on an older firmware build which is known to cause problems with many more recent roms. Most simply will not flash if not updated.
Also, by flashing your up to date firmware in Odin, you will likely fix any corruption which may have occurred on some of those partitions. Good chance you'll be able to flash whatever you want after an Odin firmware update and factory reset.
Hope that helps! Good luck!

What's up, Doc? Sorry for that...
I downloaded Odin this morning. I should have gotten the link from XDA. The site i got it from looked official, however, tons of endless pop-ups after I installed it. Freak!!!
Then found the xda links. Not sure which version to get because i didn't see which one handles the S3. The latest version (3.09) should, no?
As well, where do i get the stock ROM from? Forgive me for all these questions. Been extremely busy with work these past few months. No time to play around with my phone everything. I'm forgetting more than I know.
A full wipe was done. In TWRP, system was check (it's always checked) automatically when wiping to flash a new ROM.
Thanks again!
Everything you need is in my sig. Go to the firmware thread and the stock or root66 firmware listed there us what you flash in odin. Version 3.09 is fine btw.

Downloaded the rooted firmware from your link and the ODIN (3.09)...
Flashed the firmware (making sure to get the correct one for WIND)...ODIN did it's thing...got a green pass...the phone rebooted...got the Samsung symbol, little swoosh animation, and the accompanying sound effect that goes with the swoosh-thing...THE PHONE NEVER BOOTED UP AN O/S!
Did it at about 11:30 last night, left it, got up this morn, and phone STILL in same status!
Found out that site where I downloaded the firmware had an issue last night. They posted this morn, apologizing to people about a D.O.D attack that may have caused dropped downloads. I downloaded the firmware again this morn, flashed with ODIN, got a pass....SAME THING!!! Phone
Had to quickly pack up my laptop to bring with me to the office. Will try the official, non-rooted firmware to see if I can get it to go.
Problems' that my team went from 12 to 2 people...my partner's off today...and I got a LOUD MOUTH across from me who WILL NOT leave me alone, no matter what I say or do. LOL.
Any suggestions?
In the words of George Costanza:
"I'm BACK, babyyyyyyy!!!!!"
The official firmware worked!
Phone's back online. Thanks for all your help. Will have to see about rooting later...as well, want to see how the battery operates on stock firmware. I've tried EVERYTHING under the sun to preserve batt life and NOTHING worked!!!
Tried EVERY KERNEL noted to be good on battery life, tried TONS of apps that were supposed to help, turned off as much as I could, etc....
batt still not good. I give up. Every diagnostic app says batt is very good. I dunno...
Earplugs! Lol! I definitely feel for you about your work status! Been there!
About the firmware though, if the download had been corrupted, it would've failed the initial check done by Odin. You are probably ok. Dont worry just yet!
If it is hanging up at the Samsung screen, you probably just need to factory reset. Almost always fixes this. (It happens due to incompatible data left from your previous rom)
This will wipe internal sdcard though, so if you haven't backed up yet, the next thing to fo is flash TWRP via Odin. You can then use its built in file manager to copy whst you need first. Or you can then flash an insecure kernel and use adb if you're familiar with that.
The Doc is in!

That's EXACTLY my thought too. That was really perplexing...
I am up again...
Facotry Reset? How do I do that if stuck at the Samsung splash though?
Now that i know the official firmware works, maybe i'll, try again with the rooted firmware, try to factory reset when stuck, and continue to flash TWRP as you described above. Don't mind factory resetting. I've taken everything I need.
Oh!!!!
I noticed that all the apps I had before flashing the firmware are STILL on my phone. I would have thought that they would have been wiped out completely when lord ODIN was doing her thing.
....and battery life is STILL pretty bad...
Phone's been charging...became fully charged...unplugged it..it was down to 84% after only about 30/mins.
Will see how it goes after doing the factory wipe.
Again, how do i do a factory wipe if stuck at the Samsung swoosh after I re-flash the rooted firmware ?
Maybe your battery is dying. it happens. That would explain a big drop from the start.
To factory reset if you're stuck at boot up, turn the phone off, then boot up into recovery. Hold volume up, home and power. After it vibrates, release power only, continue holding the other two until you see recovery booting up.
If stock recovery is installed, choose factory reset.
In TWRP (probably similar in cwm) go to Wipe and choose factory reset there. In TWRP and CWM, factory resetting does not wipe your internal sdcard. Stock recovery will.
And as for Odin, it doesn't actually touch the user data partition, so all your apps and data are preserved. This is great when just upgrading from one build to the next, but is the reason a factory reset is required if coming from a non touchwiz rom.

How old is your battery? The S3 is at the age where people who bought it when it was first released will start to notice the battery is beginning to degrade.
You can also get an app called Better Battery Stats here on xda (paid version in the play store). Its the goto utility for investigating problems with battery drain. Run it for a day after a full charge and then check its logs for persistent wakelocks. The app thread should explain its use better than I can, but if you are having trouble you can always post your bbs log here for one of us to look over. (This isnt my strongest area, but there are a few others around that may also be able to help. )

[fixed] Flashed wrong TWRP, possible hard brick? Please help :'(

I've had a horrible run of luck these past couple weeks.. Deep 2nd degree burns, two broken s6 edges from sliding off surface, and a drop all at short Heights, even with case on.. So now that I was laid up in bed recovering from work accident I decided to get my tmobile p607t I just picked up and my edge all sorted out.. This is what I did:
Downgraded from 4.4.4 to 4.4.2
Towelroot and supersu
Installed titanium backup
Decided to install custom rom and make nandroid backup
Installed flashify
Erroneously installed twrp for nexus 6 (it's a real ****ty mistake I wasn't paying enough attention, probably pain killers had something to do with it and didn't realize that for all the mentions of the note in the article that they were actually linking to nexus 6 twrp)
Flashed twrp with flashify, reboot, and would only boot into download mode
Booted into odin tried flashing the same stock 4.4.2 knowing it probably wouldn't fix problem, errored out, unsuccessful
Read something about flashing twrp with odin so tried that, it didn't work, heard cwm may work with odin, Unplugged tablet from pc, power cycled, started up with black screen.
Found out it was on by plugging back into pc and odin showed "Added"
Power cycle odin shows removed and added again.
Installed adb/fastboot and drivers via installer (win7 x64)
Just so see what was going on with tab figured I would try to flash stock again to see what error was, so I would be able to mention it in this post, says no pit partition and screen is still black..
This is the point where I decided to post, during all that I did read a lot and did try searching around for something model specific, but am really concerned about doing anything else without advice.. Not really sure if it's even fixable, but hoping that because odin still sees it, maybe it's not a lost cause.. Even if it is just pointing me in the right direction it'd be helpful. I'd be willing to donate to xda's server costs if it takes really in depth help, I've benefited a lot from the site over many years and never really had to post before because I've never had any real issues, usually much more thorough with reading things. Thanks in advance.
I have family coming over so will more than likely be back to working on it tonight..
Edit:
Jesus in doing a horrible job at life.. Posted in wrong sub.. Should be in note 10.1 2014 forum, please move to correct forum.. Sorry
Edited to add:
It's fixed, I located pit partition file, loaded that and stock rom in odin, attempted to flash but it failed, power cycled and download mode appeared on tablet, without error and odin automatically began flashing, everything is back to normal..

Sprint GS3 wifi not turning on

Hello. When my device was updated to KitKat, the WiFi stopped turning on. It doesn't fail to connect, it just will not turn on at all. I tried an app called "WiFi Fixer", which didn't work, but in the "Known Issues" section it said this was caused by the "Android framework not interacting with the WiFi driver" and said to flash a custom ROM.
I rooted, installed TWRP, and flashed CM 12.1 successfully. The WiFi still wouldn't turn on. I then decided it was probably a hardware issue that coincidentally showed itself at the same time as the update. So then, I installed Cheetah Mobile launcher, and one of their themes, and was resigned to not having WiFi.
I got bored with the CM theme, and installed the Dark Material theme. At this point the phone started acting buggy, not waking from wakelock, force closing, and randomly rebooting. So i then deleted cache and dalvick cache, and re-flashed from the CM 12.1 zip i had saved on my SD. The bugs would not stop, almost making my phone unusable. The only bright side of this was that my WiFi was turning on and working! I thought maybe the hardware problem had fixed itself somehow, but I still wanted to have a usable phone. I kept re-flashing from the existing CM 12.1 zip, the WiFi kept working, but the buggy behavior wouldn't go away.
I figured that maybe the CM 12.1 zip on my SD was corrupted, so I downloaded another copy from CyanogenMod, installed it on my SD, and erased the old copy. Then, I wiped everything and re-flashed with the new zip. The buggy behavior went away, but WiFi stopped working again! I'm thoroughly confused now.
If it's a hardware issue, why does it come and go with ROMs/ themes? I thought it may be a kernel issue, so I flashed Ktoonsez K747 kernel, which is working fine, but I still don't have WiFi. Did the themes I installed earlier change the kernel in some way to make my WiFi work temporarily? Is there a fix for this? Is it a known problem? I researched the forums but the only answers I found for similar problems were from earlier versions (2013) of Android/ CyanogenMod ROMs.
At this point, I'm willing to give anything a try, I've even opened the phone, inspected, un-plugged, and replugged the WiFi antenna. If it was a hardware issue, would I expect to see any damage, like a fried circuit or something? Is there any test to check if it's hardware vs. software?Can I buy a replacement antenna?
I'm pretty broke and can't afford a new phone, which is why I'm trying to resuscitate this one When it works, it's sufficient for my use.
Please help, I really want WiFi back! Thanks in advance for any advice.
Full odin back to stock. Best solution.
Get odin here at the bottom of the page. The firmware is there too. If you create a free account the download goes much faster.
Also, re flashing the same cm12.1 over and over won't help. Have you tried the newest nightly? After odin back to stock, if you want cm, use the latest.
If you don't have a pc, you can try flashfire, but I haven't tried it.

Thanks, I'm downloading it now. Does it matter that this is an older build? I started with L710VPUDOH1, but this download is a previous version, L710VPUDNJ2.
I found this, which has the L710VPUDOH1 build in a zip...
Google > "L710VPUDOH1 opensource samsung" > first result (I'm too new on XDA to post outside links!)
within the zip is Kernel.tar and Platform. tar. which I have done nothing with, as I'm not sure if it's what I need. Do you think I should flash these? or just go with the NJ2 build?
Thank you for your insight, and taking the time to help me!

No. For many reasons. First, its not the rom, its just the update. No one has made a flashable rom zip. Second, official updates won't flash in custom recovery and it would never flash because you're rooted.
So basically its not the full rom, its the official update zip, just a patch.
Gotta flash a .tar. Unless your on the triband model, nj2 should be fine

Flashed back to stock, and updated to OH1 successfully, but still no wifi. It's greyed out and won't turn on
I would think it was a hardware problem, except that it all started when my phone updated to 4.4.2. I've found many others with this problem online, but no fixes. Can I flash back to 4.3? or can I flash a new modem/radio(?) file. I thought I saw one in my searches but can't seem to find it now
Thanks again

No, do not try to flash 4.3. You will hard brick, and your phone will be a paperweight. Same thing if you try flashing any pre Knox modems/radios.
Are you flashing something else with this? It's something on your device if a tar flash in odin didn't fix it. Did you factory reset after odin?

Yes, I factory reset, cleared all caches, rebooted into safe mode, changed wifi settings in service mode... did an ancient Indian wifi fixing dance, spoke soothingly to it, then cursed at it :laugh: maybe it's a hardware problem with coincidental timing that's also happened the same exact way to other people

Lmao, funny. I heard it happening to people a while back. Can't remember what caused or fixed it. Some fixed it with custom kernel but the kernel is waaay outdated now. But it was kt747 by ktoonsez. But its so old. What carrier are you on? Sprint, virgin Mobile, boost?

this just happended to me the other night actually, did you find solution? Apparently just taking out the battery and resetting solved it for a lot of people, but not me. I will tell you what did work though! (keeps randomly doing it again but at least i can gfet it to work aghain even if only for a littlw bit)
First check with root explorer if you have this fike "data\misc\wifi\wpa_supplicant.conf "
I guess it has something to do withthis file, and your android not writing to the right spot, but i honestly have no idea so ill continue. what i did (i saw i didnt have the file either) i dialed *#0011# then hit menu, and then hit wifi, and turned off the bottom switch "wifi power save mode". I exited service menu tried wifi a couple times still same thing, so i went back into service menu and reenabled the switch, then i turned off the phone by pulliung out battery. I logged into my custom recovery and checked out the file explorer in twrp, and voila there that mysery file was! So i cleared dalvick and cache, rebooted into rom, (wicked x v8.2) and attempted wifi and it was working again. so take whatever conclusion youd like but im too tired to keep my eyes open at the moment and good luck, pissed me off cuz wifi was all i had no service, of course

I have that file on my phone. So I understand, you originally didn't have that file, but after doing the steps you listed it magically appears, and then wifi works? I really wish I could get it to work. Also, you said it keeps happening... so the file keeps dissappearing on you? Thanks for the response.

Help - Galaxy Tab S 10.5 Bootloop Out of Nowhere

So...
Last week, my wife's Tab S went into a bootloop. She runs complete stock, we haven't rooted, or anything. There had been a notification about an update, but she hadn't touched it. She'd updated to Lollipop at some point last year, but hadn't applied the absolute latest update. One day last week, she just turned it on, and it started bootlooping.
Because it was so stock, there were no backups, no nandroids, or anything like that. No Custom Recovery. I told her "well, we can just do a factory reset. You'll lose everything, but once we get you back up and running, it'll just re-download everything from the Goog." So we factory reset it. Looked good for a minute, booted into the first screen, enter in your Wi-Fi password, all that. As soon as we got the Wi-Fi password entered, however, it re-booted. And keep rebooting. Bootloop city. No problem. I walked her through (over the phone) using Odin to flash the latest Lollipop firmware. No dice. It appeared to flash successfully, but still bootlooped.
Over the weekend, I tried using Kies to flash the most official firmware I could find. Everything was successful -computer recognized the device, was able to download "direct from the source," as it were, but it got stuck at 69% twice before failing. I read somewhere that one had to run Kies in administrator mode to get it to successfully complete. So I did, and it got past 69%, successfully completing the flash. STILL NO LUCK. STILL WITH THE BOOTLOOPS.
Last night, I realized that I hadn't flashed in Odin using Administrator Mode. Tried it, using latest 5.0.2 (XAR-Cellular South). Flashed successfully, all appeared well. Still bootlooped.
So, I'm stuck. I can get into recovery, I can get into Download Mode, I can successfully flash. I just can't get the darn thing booted.
Thoughts, anyone? Should I try flashing a Custom ROM? How hard is that using Odin? Thanks in advance.
Ok this will take a few tries but here is my method of dealing with this situation
1) Flash stock using Odin
2) AS SOON AS the screen goes blank, start holding Power+Volume Up+Home
3) When recovery boots, release the buttons
4) Use the volume buttons to select "Wipe data/factory reset"
5) Press power to confirm
6) Reboot
If that doesn't work, you may either:
1) (more likely) Installing a ROM will fix the problem
2) (unlikely but possible) You might have worn NAND pages, which I doubt but could cause this behavior.

Thanks, I'll try these steps tonight when I get home, and report back!
All right, here's something interesting. Before I tried your first step, I remembered that the other night, I left it stuck at the Samsung logo -it was just kind of stuck there, and since the behavior was a little different than I'd seen before (not continuous bootlooping), I thought I'd boot into recovery and wipe. I did, I wiped (factory reset), and rebooted. The tablet booted into the first screen, Accessibility/Wi-Fi, blahblah. This was where it usually rebooted. On a hunch, I bypassed entering in my WiFi key. I then bypassed almost everything else (Samsung account, Google account, etc.), expecting that the tablet would reboot at any moment. But I made it to the front apps page, where it shows you the side-launcher, the Magazine-Flipboard thingie, and whatnot. Wi-Fi still not connected, though. I opened up the app drawer, and scrolled around. Looked really good for a moment. I even took a picture with the camera, and viewed it in Gallery! Feeling brave, I thought, "well, maybe it just needed a couple of minutes before firing up the radio." So I went into settings, and inputted my WiFi key. It connected. And rebooted into its bootloop. (getting so tired of that boot-sound).
Went ahead and flashed the most original stock firmware I could find. As always, flashed successfully. As soon as it booted, I made my way to recovery, and wiped, per your instructions. No luck. Bootloop again.
It's something in the WiFi is what I've come to think as a result of the above. Which I don't entirely understand, as I thought the radio got re-flashed with the firmware.
I'm ready to try flashing a Custom Rom. Can I do that through Odin, or should I try and flash TWRP, and do it through there? Will TWRP flash without a working (bootable) OS?
All right. Thanks for your response!
Try this as a test.
First make a full backup of every partition with twrp including the EFS <<IMPORTANT!
Get it booting again without wifi then root the device and delete the EFS folder or delete it in recovery.
Reboot the device and try and enable wifi.

Got TWRP installed. Won't backup. Fails at 16% (system partition, I think). Just powers down to battery indicator in the middle of the backup. Looks like it backs up the EFS, though, since it's the first one. And when I go into TWRP's Restore option, there's a backup there (though I don't dare try and restore it).
Now I have to figure out a way to get the Custom ROM and GAPPS I downloaded onto the tablet without a reliable boot... It's gotten to the front screen a time or two tonight, but starts looping even when I bypass the WiFi setup.
Entered adb/TWRP interface. Tried to push two files, a Custom ROM file, and a GAPPS file. The ROM failed, with some sort of "Error 7," incompatible data, blahblah... Just out of curiosity, I tried to push the GAPPS file, and that failed after about 6%, and the tablet powered off.
I'm running out of ideas.
copied a custom rom to a USB/OTG stick (thumbdrive), and plugged it in. Fired up TWRP, tried to install. Wouldn't. Wouldn't install GAPPS, either. Looks like the only way it wants to flash anything is through ODIN or KIES.
The Latest...
All right...
I remembered that sometimes the TWRP version mattered. When I installed TRWP last night, I installed the latest and greatest, 3.0.2. Last night after I gave up, I remembered that sometimes, the latest and greatest TWRP doesn't install things perfectly. So, this morning, I downloaded TWRP 2.8.6-ish onto the USB/OTG device, and re-flashed the recovery partition. To be honest, I was surprised that TWRP was even able to flash that (but the TWRP image is only like 9.8 MB, so...)...
Got TWRP 2.8.6.0 flashed, and rebooted into TWRP. Immediately decided to try and re-flash the custom ROM that I'd tried unsuccessfully to flash last night, since the thumbdrive was still plugged in. Resurrection Remix Lollipop. Lined up GAPPS in the queue, as well. The ROM *appeared* to flash better than it had in TWRP 3.0.2, but it was sort of hard to see... GAPPS failed, and I was prepared to watch another round of bootloops. It did bootloop, sort of. The RR splash screen appeared, said that it was installing (or preparing) xx out of XX apps. Then, it rebooted. I figured it was doing its bootloop thing. However, it got to the same screen, "installing xx out of XX apps. Except that XX number had gone down, and the xx number had gone up. It repeated this action about 4 times --the last time I saw it reboot, it was "installing 1 out of 2 apps." And then...?
It booted into the RR lockscreen.
Of course, there were no GAPPS. In fact, there are something like only 20 apps total on the tablet. But it appears somewhat stable at the moment. (See picture).
Afraid to try and connect WiFi, afraid that it'll just bootloop.
Speaking of bootloop. At one point, once we got it booted, my wife hit an option in the Settings. LCD Density, I believe. As soon as she hit it (she literally just placed her finger over the 320 default option), the tablet rebooted. No loop, though. Rebooted straight back to the RR lockscreen.
So I appear to have a somewhat stable OS flashed onto the tablet at the moment. No GAPPS, though. No WiFi.
Anybody have a suggestion on where to go from here? I have my doubts as to whether or not I can even back up this configuration.
Sorry about all the updates. I kind of figured that if *anyone* else ever goes through what I'm going through, they'll have some sense of all the different things that can be tried in resurrecting a bricked/bootlooping device. I appreciate everyone's efforts to date -thank you so much, @Lightn1ng and @ashyx.
All right, because I can't leave well enough alone....
I got WiFi up and working. Tablet still stable and working. Wheeeee.... No GAPPS, though.
Downloaded GAPPS, second-smallest package from opengapps- only 128M (5.1 ARM package). Downloaded it in Android, from the tablet! Tried to flash it in TWRP. Failed, tablet rebooted halfway (not even) through. Now it's bootlooping again...
I should've left well enough alone, and waited for someone. Have tried re-installing Resurrection Remix, but tablet keeps failing to flash. Might have to try and flash a different TWRP. I don't know...
Have you tried another Gapps? Also, is this the WiFi only model or the LTE model we're talking about?

It's the WiFi-only model - SM-T800.
It's kind of weird. I thought it might be some sort of internal memory problem (like the worn Nand pages you mentioned), since almost anything I try to do in TWRP fails (although I was able to flash an entire Custom ROM the one time AND get it booted) -but backing up isn't working, whether it's to internal/external SD. And the fact that I can flash perfectly (subjective term there) well using Odin or Kies tells me that whatever problems the tablet is having, something's getting through.
I'll try a different GAPPS package. Right now, though, TWRP isn't letting me flash hardly anything, and moving files back and forth on this thing is just awful.
AGH - I was so close!

Maybe somebody else with a T800 could backup their entire EMMC using
Code:
dd if=/dev/mmcblk0 of=/sdcard/full_nand_dump.bin
And you take the file on your tablet and do
Code:
dd if=/sdcard/full_nand_dump.bin of=/dev/mmcblk0
And restore YOUR efs folder using TWRP.
THIS IS A DANGEROUS OPERATION AND I AM NOT RESPONSIBLE FOR ANYTHING THAT GOES WRONG!

@ashyx Any more ideas before I go ahead with my evil world domination plan to recover this device?
I wouldnt carry out any risky operations until a full backup can be made with twrp or you may end up with an unrecoverable device.
If twrp cannot backup the system partition then there is an issue with the partition.
Try backup again and post the recovery log, it may contain some relative information.
I have the same issues and have tried eveything. I was rooted and running the latest Pheonix rom on my sm-t800. Last Wednesday (8-10) I starting getting boot loops out of nowhere, no new apps nothing just a daily driver. I've been through everything on here and have gone back to bone stock but to no avail, the boot loops just keep coming. I can connect to wifi and get things set up but if I try to use anything more than 'light usage' the tab starts its boot loops again and rows fits for about 10 minutes and always different timing on the boot. Sometimes it will make it to the Samsung logo, sometime only to Tab S and sometimes about 10 seconds of usage.. I know this isn't helping much but wanted to let you know there are more of us with the same problem. Will be blab to try anything to help said issue.
Exactly the same issue on my LTE version.
Samsung support just asked me 230€ for a new motherboard.
I refused to repair. I think it is related to nand memory..
Hello I have both the 8.4" and 10.5" I updated the 8.4" to Android 5.02 nothing but boot loops my other is still on 442 and I wont be updating it as its working fine. I have been reading a few posts and the problem was right in front of me all the time I have 2 internet connections 2.4 GHZ and 5.0 GHZ if I connect to the 5.0 GHZ I get boot loops but if I stay on 2.4 GHZ no problems what so ever so I may just install a custom rom and my 10.5 tab and stay clear of the faster internet.

Galaxy Tab S 8.4 keeps soft-bricking itself.

Hi, everyone.
As I have discussed in my two previous threads, my Samsung Galaxy Tab S 8.4 has been constantly forcing itself into a bootloop and refusing to move past the Samsung logo.
Since my last thread post, I had decided to upgrade from KitKat 4.4.2 to Marshmallow and for about a month and a half, I have not had the bootloop issue. A week or two ago, the device began going through the same bootloop issues after the screen freezes and either I force-reboot it by holding down the Power button and Volume Down button, or the device reboots itself. I have cleared the cache partition each time this happens with no successful result.
The only way I have found it to have started working again is to wipe the cache partition, factory reset the device, then wipe the cache partition again and flash the official Marshmallow ROM. So far in the past one or two weeks, I have had to factory reset this device at least five times (around two to three days after the last time it was reset) and it's just becoming a nuisance.
Is there anything that anyone could suggest that might work so that I do not have to factory reset the device and flash the ROM on such a consistent basis?

I used Odin but skipped past Lollipop to Marshmallow (the ROM was the Official ROM from Samsung Updates). I don't think the file was corrupt as I had this problem with the tablet before I started flashing the same KitKat ROM it was originally preinstalled with, and Marshmallow later on.

Well if update with the rom that you got from updato there would not be a problem....in my experience if a download take a long time it has a greater chance of having issues if it is a fast clean download it would be clean with no errors.

I don't think the issue did start with the update. If anything, flashing the ROM (combined with factory resetting) seems to temporarily fix the bootloop.

When a download is slow it get interrupted with advertising bots and sometimes depending on were the errors happen it may have been a crupt....i had the same problem with t705y and t805y until i download it from updato now i get nothing no errors......just my experience thats all.

Ah, I see! No worries, I'll download the ROM again and make sure the download isn't interrupted. Thanks for the advice! I shall let you know how it turns out.

Well, this may not get to the root of your problem, but it's a bit of a no brainer really.
If your having to restore your device so much why not just bung twrp on it, make a device back up, literally a few minutes and if it all goes Pete Tong again, simply boot to twrp, hit restore and you're back up and running in a few minutes?
