So today I was looking at the ElementalX thread after I update to GPe 5.1 earlier in the week. I saw that a couple of people had the kernel working fine, so I decided I would flash it and see if it would work fine for me.
Of course, that was not the case. It got stuck in a boot loop, getting past the boot logo and to the "Optimising apps..." stage, every time. So I decided to flash the stock kernel back, but when I upgraded to 5.1, I didn't flash the new firmware, so I thought that this would be a good time to do that. After I did, I managed to get into Android just fine, however I had no WiFi. So after some restarts and clearing caches, etc, I decided to flash the firmware for 5.0.1. Same again. I found another GPe radio posted somewhere on XDA that was flashable in recovery, but same thing. I get a 4G signal fine and Bluetooth appears to be working.
Amongst all of this, now when I plug my phone in via USB neither my Macbook or Windows PC are picking it up...eurgh. I just don't understand why it is doing all of this when I'm sure it is now back to how it was before I started this morning? Would it just be easier to flash the 5.1 RUU to my phone now, or will I most likely just get the same problems?
Thanks in advance!

Yes, it would be easier. RUUs are the safest way as well. You'll lose all of your data though, so backup anything that is important to you (photos, apks, zips, etc.)

Yeah, I ended up doing this and it's working now. Bit annoyed though because I kinda forgot to move things from my /sdcard/ folder, thinking that it wouldn't get wiped...
Whoops. At least it's all working now though
I've been trying to find a solution to this all day. Here's the basic gist.
I'm rooted, and have been running CM11 since November. A few days ago, I got an update that CM12 was available, so I went ahead and allowed the tablet to update. After updating, I was getting an error message regarding Google play services being unable to update. OK, fine. After trying several things, I finally just decided to format my tablet and start over. However, when I selected "format device" within CM12, I ended up in an endless loop on the TWRP screen.
So...this morning I decided to reflash the stock firmware. I downloaded a copy from Sammobile, and using ODIN, and flashed it onto my device. Now it sticks on the Samsung logo. What am I missing here?
Thanks in advance!
Cool
Holy Cow - I think I got it. I finally found a thread on here that explained how to get into recovery mode so I could wipe the device and reload the firmware. That appears to have done it!

Hello Everyone,
I've been up literally all night (I know, that old line) trying to fix what happened. I bought this phone last year. It was unlocked and rooted. I never updated because it was never giving me issues. But the lagging and battery has finally got to me. So I decided to upgrade to this new rom(http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-0-t3094423).
It looked clean and minimal bloat, just the way I like it. However, I didn't get past updating the Bootloader. As soon as I did in Odin it went into a bootloop. Try as I might I couldn't get into recovery. Luckily I can still get into download mode. So I read up and found that I should flash the original firmware. Unfortunately it failed because I tried to upload an older version. Is there anyway I can flash this rom via odin? Sorry for the noobish questions here but it's past 8am and I've just about given up. If I see recovery is not seandroid enforcing or rev check fail s6 device 3 binary 2 I'm going to lose my mind lol. I did have TWRP installed if that makes a difference. Just can't access it. Any help would be greatly appreciated. Thanks guys
P.S. I know I used buy instead of buy but can't fix it. It was really early in the morning haha
Ok I managed to download the stock MM version for my phone. I still have bootloop issues but I'm in recovery mode at least. However not TWRP though, if I try downloading a custom recovery it says the dreaded "recovery is not seandroid enforcing" also it says Device does not have DRK. Any guesses here?
Well, I've just about given up. I've searched extensively and it appears that the fix is to download a different kernel. However, the G925T has no support yet for any custom MM kernels. I made a backup of my phone via TWRP before this whole mess but the problem is I can't get to it. And to be honest I'm not entirely sure if it's still there. Here are the steps I have taken thus far.
1. Downloaded MM Bootloader: this was the start of my issues. Started bootloop, couldn't get into recovery.
2: Attempted to download original LP firmware: Odin denied it, there was another version I download from zidroid called "downgradeable". Obviously did nothing because I was still running MM bootloader and was effectively the same thing.
3. Downloaded stock MM firmware: Finally was able to boot into recovery but it was useless as it was the stock one. Also wouldn't boot up due to "Device does not have DRK" and boots straight into download mode. Tried to download recovery but none of them worked. Kicked me back to "Recovery not Seandroid enforcing".
So this is where I'm at, I just want to get back to my old device I honestly would rather have a clunky phone than one that doesn't work at all. Is it possible to downgrade back to LP and get back into TWRP and flash my backup? Do I still have root after taking all those steps? Any help would be greatly appreciated because this has officially ruined my weekend?
I guess I'm talking to myself here but if anyone ever encounters this issue at least it will be documented if I ever do fix it.
I managed to get into TWRP. Although arter doesn't have a kernel that supports our system yet. The twrp recovery he has does, ours is compatible with the fi variant. Again that's only the recovery no the kernel.
So I was at a cross roads, do I restore my backup or do I continue with the download. Unfortunately none of those options worked. When restoring the backup I get stuck on the samsung page with "kernel not enforcing" or whatever. Do be fair, before I did this with my device it had already said that. So I gave it some time, but alas no luck. And the same issue with the when I tried to continue the download. I'm a little lost as to how to continue now. I just want my device back.
try dd the mm firmware

Not sure what state your phone is in. To begin with, the not Seandroid message with recovery is normal, if you are on marshamallo. If you are on LP then you get the same with the Kernel message when it boots up. BOTH are normal depending on which Firmware you are on. But that said you shouldn't be trying to downgrade, if that's even possible. Have you tried smartswitch and the emergency software restore function. It will wipe out everything on your phone but at least will boot up with the latest MM. Then simply Odin the arter TWRP and then install XTRESTOL which I am using NO PROBLEMS on my TMobile 925T variant. NOT sure about the DRK root key problem. But when you install stock MM with smartswitch you should have also gone into settings and enable developer settings to make sure OEM unlock was enabled before doing anything else.
Lastly, the Arterkernel will actually work fine as far as booting up. The ONLY issue is call audio which we all are waiting for a patch, or a kernel that supports everything. But, I have TWRP installed that arter kernel, and the phone boots up just fine. You just do NOT have call audio. My suggestion at this point is smartswitch. Just know your serial number so that when asked you can plug that in to the menus smartswitch goes thru before wiping and restoring current MM latest and greatest.

Thanks for the reply, I don't have the box for the phone and couldn't boot it up so that was a no go. But luckily for me I decided to give that rom one more go. I flashed bootloader and modem again, then flashed TWRP, and finally installed the rom. And boom! It worked, and it's better and faster than ever. I'm not sure what all that other mess was but I am going to say I have everything I need at the moment and won't be flashing anything anytime soon. I've learned a great deal through this process though. Thanks for everyone's help.
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.
