So my phone is stuck in bootloop. and I cant get my phone to boot correctly.
To start, I was running 4.2.2 AOKP for about half a year and it started to not work as well. Force closing alot, freezing etc. So I decided it was time to update. While I was running AOKP, I experienced bootloop almost every time I turned off my phone. This became regular, but by pulling the battery and trying again (sometimes I had to do with a few times) it always got working again.
I went and found the new 4.3 Carbon ROM and decided that looked cool and would be a nice upgrade. So I downloaded it and the new 4.3 gapps. Put them on an external sd card, and put it into my phone. I then booted into CWM and did a factory reset. Then I went and installed the Carbon from the external sd, installed gapps, and rebooted immediately. I was then, and still am, stuck in a bootloop.
I can restart my phone go back into clockwork.
But I cant get the phone, despite all my efforts, to boot correctly. I have tried to wipe caches, wipe dalvik, format system. All of it. yet I cannot boot correctly.
I really need a working phone. Any help would be really great.
Thanks all
Also, I am using TWRP 2.6.3 to do the flash of the Carbon after it failed the first time

2.6.3.0 seems to be giving many people issues. You need to install 2.6.1.0.
And is your radio up to date? Only 2 work...the new T-Mobile and Telus radios.
After those 2 things are taken care of, you should be fine. Tho lots of things can cause boot loops, and there's many.. many posts about it. If my suggestions don't help.....Search and read up. Try some various fixes.
Maybe try a different rom too.

Hope you did a nandroid backup in recovery? Restore it if so. If not, you may need to start from scratch and Odin flash stock rom, flash recovery and root again.

flash stock rom zip via odin then you should be good to root and try to flash another custom rom again:good:
Hello all!
This is my first foray into the world of custom Android systems, and I'm having a hell of a time with it... if somebody would be able to help me out, I would greatly appreciate it.
First off, the situation:
I am on Sprint, and I recently bought a Samsung Galaxy S3 (SPH-L710) from Sprint to use as a backup phone, I used it for a while on Stock, then deactivated it so I could give it to my wife. First though, I wanted to put a custom ROM on it, and experiment/play around a bit and see what this world of options could do for me. Long story short, I ended up flashing an AICP ROM, and everything seemed to go smoothly, but when I went to activate the phone on my account again and it would not work no matter what I tried (details below). I figured maybe I could activate on the stock setup then just restore my custom setup, so I tried to revert to my stock ROM backup and I couldn't do anything because I was constantly getting messages that various programs had closed... Then I tried to wipe and restore my custom ROM backup and I get stuck in a boot loop... so I tried to flash a stock recovery and I get stuck in a boot loop... I'm out of ideas here, and now I'm stuck with a phone I can't use or do anything with, and I can't activate.
Details:
The initial rooting/install process seemed to work ok, and was fairly straightforward. I followed various guides on http://galaxys3root.com/ to get my phone rooted and backed up (Don't recall which ones now, but I've read through so much by now I don't know if it matters...).
My phone:
Samsung Galaxy S3 (Sprint) SPH-L710
Modem: L710SPRDNJ2
My Desktop:
Debian Linux
Here's the steps I performed:
Rebooted phone in Odin mode
Downloaded CWM S3 Sprint Recovery from the http://galaxys3root.com/ website (can't find the link any more)
Flashed the CWM recovery using Heimdall then rebooted phone into CWM
Installed SuperSU through CWM, then rebooted
Checked that the phone was rooted successfully (it was), then ran Titanium Backup on the whole device to my SD card, then copied the backup files to my desktop computer
Rebooted into CWM, and performed a backup through CWM, then rebooted and copied the CWM backup to my desktop.
Downloaded AICP Rom for my phone from here: http://downloadandroidrom.com/file/GalaxyS3Sprint/roms/AICP/aicp_d2spr_lp-10.0-RELEASE-20150707.zip, put it on my SD card, then installed it through CWM and rebooted
At this point, I was happy with how everything was working, so I did some minor theme customizations then made another backup through CWM, and copied it to my computer, but I did NOT run Titanium this time...
After all of this, I tried to go ahead and activate it through the Sprint web service. This process failed continuously with an unhelpful error message of "Sorry, this device can't be activated right now". I then got on Chat to see if they could activate it manually, and then the problems began. They did their thing activating the phone, but when I booted up I got no data connectivity, and couldn't make calls, and the SIM was not changing over to the new number. I was on the chat with them for over an hour trying to get the situation resolved, but that finally ended when they started asking me to punch in ## codes, because I discovered that none of them worked on my custom ROM. Some quick research told me that this was non-trivial to get around so I had them switch everything back and I started researching the issue.
I found this thread: http://forum.xda-developers.com/showthread.php?t=1626638&highlight=sph-l710 that looked like it would let me do what I needed from the custom ROM, but I couldn't tell if it would fix my problem for sure, so I figured "I'll just restore my stock setup from that backup I took, activate it and update, then start over". This is when things got really frustrating...
First I rebooted into CWM, went to 'backup/restore', and restored my stock backup
Rebooted, and as soon as I got past the lock screen, I get inundated with messages of various apps being closed unexpectedly.
I researched a bit, discovered the issue may be caused by stale dalvik cache, so I rebooted into CWM, cleared the dalvik cache, formatted the /cache partition, then tried to restore the stock backup again, but this time I get stuck in a boot loop.
I then rebooted into CWM, tried to restore the backup of my AICP ROM, only to be stuck in a boot loop as well.
Trying to get into any usable system, I rebooted to CWM, cleared dalvik cache, then formatted /cache, /data, and /system just to be sure, and re-flashed the base AICP ROM I started with. This worked fine, and before long I had stock AICP back
Since I still couldn't get the phone to activate in the custom ROM, and my backups are apparently completely useless, I rebooted into CWM, wiped dalvik, /cache, /data, and /system again and tried to install a different stock ROM I found in the XDA forums (here: http://forum.xda-developers.com/galaxy-s3-sprint/development/stock-rom-4-4-2-t3010642) only to be greeted by another bootloop
At this point I've spent well over 24 man-hours trying to get this to work, reading, researching, flashing, etc all to no avail. Nothing I do seems to work, and it seems like every article, tutorial, or forum thread I read either has nothing to do with my device, is too old, or doesn't describe my problem.
I'm at wits end, and am so frustrated I'm ready to just give up and smash this device and buy a new one... My questions to the community are as follows:
I know I screwed up on a couple of things, but in my initial research of doing this there was no indication that these were even things I needed to watch out for... Is there any more organized sources of information for doing this sort of thing?
Does anybody else out there use Sprint on a custom ROM, and if so how you you pull this off
Where else have I screwed up, and how can I fix this situation? (My end goal is still to get the S3 onto Sprint with a custom ROM)
What can I do differently next time? I would like to figure this out and do it to other phones and devices I have, but if it's this much trouble every time, I just don't have the time to mess with it.
Thank you in advance, and I appreciate any information that the community can provide.
This sounds like a CWM problem to me. If I were you, I'd boot the phone into Odin Mode and flash TWRP ( www.twrp.me ) then try flashing the latest aicp nightly downloaded from the official site ( www.aicp-rom.com ). Check the md5sums on everything! Then maybe try flashing a touchwiz ROM and activating your phone. Remember that you need to wipe the internal storage when you go between KitKat and lollipop.
I'm fairly certain you have to do activation with the stock Touchwiz roms -- once the phone is activated you can flash a custom.
You should go into recovery and wipe everything (System/data/etc) EXCEPT for the External SD Card
Power off - pull the battery for a few - power on directly into download mode
Odin NJ2 back onto the phone and reboot and activate it (skip through most of the setup since you'll flash a custom after)
Once you know it's activated and working under the stock Touchwiz, then again power off and Odin TWRP recovery
Then you can go back into recovery, wipe everything except External SD, and flash the custom rom back on.
Looks like swapping CWM for TWRP did the trick.
Flashed TWRP no problems, and put CleanBean on there to get the phone activated. Still wouldn't work automatically over the Sprint website, but I got on chat with them and they fixed me right up. Downloading a fresh copy of AICP now...
Is it worth it to keep the CWM backups I made earlier, or should I just go ahead and flush them? I figured just get rid of them since restoring them wasn't working anyway, but I figured I would ask.
Now to move all the data over to the new phone. Thanks so much for your help guys!

Get rid of them. TWRP can't restore CWM even if the backup is good
All I want..... Is an S3 with AICP on Sprint's network.
Two weeks ago I bought an S3 for $50, started playing with it, easily flashed AICP and TWRP 2.8.7.0 Recovery. Everything was awesome, until Sprint couldn't activate it. I flashed back to stock through Odin, Sprint still couldn't activate it (problems with programming). There was no Sprint boot screen, so assuming that was the main problem I found "SPH-L710_ND8_Full Restore_UNROOTED.exe" that restored the Sprint boot logo and viola! I had Sprint 4GLTE and talk and text.......... But now, this little devil S3 won't flash Roms that are 5.0 or newer. I have tried AICP, PAC-ROM, Vanir, Exodus.... all just boot to the boot logo and stay there, but when i try Gummy 4.4.4 it boots and works fine.
I always wipe cache, dalvik, & use correct gapps. Using TWRP 2.8.7.0 and have tried two other recoveries with same result. Tried flashing L710VPUDNJ2_L710SPRDNJ2_L710VPUDNJ2_HOME.tar.md5 through Odin and then reflashing recovery and retrying ROM, same result.
Right now its working fine with gummy 4.4.4 but I want 5.1-6.0 because that's the only way I will feel ok about having an S3 I'm sure I'm forgetting some details as this has been a two week off and on thing trying to get this phone to work, so if I am please forgive me and have pity (I'm using a blackberry Q10)
Why will lollipop roms not boot?!?!?!
Please..... help me obi wan kenobi...... you're my only hope

If you the original Sprint S3 and not the new Sprint Triband S3 then you should not have any problem at all! How long are you waiting on it to boot? I had the new Triband model and I had and I thought the lollipop roms wouldn't boot either but I had to give it 5-10mins sometimes on the 1st boot!

I have let it sit overnight a few times now.... just to make sure. With the Gumy 4.4.4 Rom it only took about 2 minutes which I was shocked by.
I feel like I have literally tried everything.

Yea Kitkat roms don't take very long on 1st boot anymore. But as for lollipop what all roms have you tried flashing?
There's only 2 reasons I can think of that they might not be working. 1st is your model SPH-710T or SPH-710 and 2nd are trying to flash a custom kernel with it?
Another thing I feel like is worth mentioning.... When I first flashed the AICP Rom I played with it for a few days so i had all my stuff installed. Realized I had to flash to stock to activate on Sprint so i made a Nandroid backup of my AICP 5.1 setup. When i restore this backup it boot loops as well.
Tried restoring everything except data, wiped dalvik and cache, all using the same twrp recovery. So strange...

I have tried AICP, PAC-ROM, Vanir, Exodus.... all just boot to the boot logo and stay there. Mine is the SPH-L710 not the triband 710T. The Roms I tried to install, as far as I know, come with the kernel in the ROM zip. I have tried AICP and the pac-rom with just the rom zip and gapps, as well as with a few custom kernels just to see if it would change anything.
Ah another thing, may be unrelated because I only get this when flashing AICP and Pac, it says "unmount of /system failed; no such volume" and then flashes boot img and seems to be successful.
When I flashed exodus and Vanir it does not say this, and all seems to go perfect..... buuuuuut still boot loops/gets stuck at boot animation
Even tried flashing rom and gapps via adb sideload
I have a bad esn l710 in really poor condition. Just flashed the same recovery, same AICP rom, same gapps, all from the same SD card, and this one is working fine. Boots up in just a few minutes.
So i have to be missing something or something is wrong with the one I can actually activate.
EDIT: So "unmount of /system failed; no such volume" error doesn't matter, same thing happened on the bad ESN device that booted up fine.
Update (if anyone cares lol): I flashed both devices completely to stock with the "SPH-L710_ND8_Full Restore_UNROOTED.exe" and then did the exact same thing to both devices, twrp>aicp rom>gapps>dalvik>boot, the bad ESN crap device boots AICP fine, the good condition good ESN one boot loops forever.
I am at a loss here, both devices are exactly the same SPH-L710, flashed to stock completely, but the one with a good ESN that would actually work will not boot lollipop roms. I disassembled both devices to look for hardware differences of any kind, they're identical (with no signs of damage). The only difference is the bad esn one is a slightly deeper shade of blue. I'm pulling my hair out.
I even tried using the force, but my midichlorian levels have never been that good.
Who knows man
I've seen this only a couple times. One guy had luck. When it was stuck, he just kept randomly hitting the power button and eventually long pressed until it was about to reboot (screen freezes for a second) and when it shut off, held home and volume up so it booted recovery when it came on. Then just rebooted system, and this time it booted. Also, sometimes when going back and forth between KitKat and lollipop, you need to wipe internal storage. Make sure you have the latest twrp too (2.8.7.0).
Just shots in the dark, but you never know.
I saw one member who was never able to boot lollipop roms, you would be the second. So its pretty rare.
Well you now know 3 people that cant flash lollipop roms on an l710 NON tri-band.... Ive tried all of them including a couple of Vanir 6.0 roms and the ONLY one i could get to take was a BeanStalk 5.01 rom and a Candykat only after flashing its KitKat predecessor... All KitKat roms work just fine.. Curious,, as I also used the same odin non- rooted rom to get back to stock and after that had trouble flashing lollipop roms period.. Maybe something with the symlinks in that un-rooted rom??? I'm at a loss myself...

As the only possible solution I have not tried, I will attempt to randomly press/long press the home button as it boots and then boot recovery..... lol
What's even weirder is it worked fine with AICP lollipop just about a month ago, before i had done anything to it. but I repeated all the things i did to it on another s3 and that one still worked fine with lollipop roms.

I have similar probl.
After 4 months with CM12.1 I'm flashing NJ2 and upd. to OH1.
After THAT - I cant to flash anything ROM lollipop and higher.
I dont know, what is it.
I was waiting for 4 hours, 8 hours, 12 hours, a day!
I dont know, I dislike TW roms, help anyone!
CyanogenMod 13.0 D2SPR
...I dunno, wanna start from scratch?
http://forum.xda-developers.com/galaxy-s3-sprint/development/rom-d2spr-cyanogenmod-13-0-t3248561
- Use the Sprint-made TWRP .img in the OP with Flashify (from the Play Store)
- Flash a CM 13, add GApps (from OpenGApps), and a recent SuperSU.
I'm a bit of a half-no0b, so I may be talking out me pants.
Bonne chance!

Yep!:crying::crying::crying:
I had the same problem. Try this. It worked for me today.
I have a d2spr (originally from sprint). It is now activated with boost. L710VPUDOH1 bootloader and baseband. CF-Auto-Root-d2spr-d2spr-sphl710.tar.md5 flashed with odin for root. twrp-2.8.7.0-d2spr.img.tar.md5 flashed with odin as recovery. I backed up Apn's with "APN Backup & Restore" app. I wiped system, cache, dalvik, data. Flashed cm-12.1-20151117-SNAPSHOT-YOG7DAO1K7-d2spr.zip... . Flashed pa_gapps-modular-full-5.1-20150315-signed.zip. I Wiped Dalvik. The device booted smoothly within approximately 7 minutes. I had full function as far as I could tell. Everything worked well. Ran this setup for about a month. I decided to restore a stock w/root backup made with twrp2870. Bootlooped until I learned to wipe internal sd when going back to 4.4.2. I wiped the internal sd and successfully booted stock w/root backup. When I tried to go back to cm 12.1 backup, I ran into the same problem... boot loop for hours. Multiple times. Backups and different nightly zips. I found and flashed every custom recovery I could find for this device to try to make it work. Eventually... while I had twrp-2.8.7.2-d2spr.img as my recovery (not sure if it makes a difference or not). I found this...
(apparently the link is not allowed due to my lack of posts with this forum)

Ha! Got it! Visited the #cyanogenmod channel on freenode irc and there were some VERY helpful people there. So I've got a few instructions.
Flash the latest TWRP recovery via ODIN. (2.8.7.0-d2spr at the time of writing).
Flash your CM 12 zip file
On your PC (with adb installed) run the command "adb shell dd if=/dev/block/platform/msm_sdcc.1/by-name/persist of=/sdcard/persist.img"
Then run "adb pull /sdcard/persist.img" (This will give you a backup of the persist partition in case anything goes wrong)
Run the command "mke2fs -t ext4 /dev/block/platform/msm_sdcc.1/by-name/persist"
Run the command "adb reboot"
If it boots into OS, great! Reboot into recovery and install the lastest gapps package.
I did it from adb in a Cygwin64 Terminal. The device booted my cm12.1 backup the first time I tried. I think it would work just as well with adb from a windows command prompt. I only found this on another page. Credit goes to someone from "#cyanogenmod channel on freenode irc". Hope it is as much help to all of you as it was to me.

I flashed mine back to stock and sold it.... got a good deal on an S5 and flashed MOAR to it.
I found this thread a while back and attempted to do what it says to do, but I couldn't get it to work for me. What exactly does running those commands do that suddenly makes it work?
I think it either reformats or converts the persist partition to ext4. I'm not 100% sure yet bc I haven't had time to look into it.

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.

Why not just update to Marshmallow? Absolutely no issues for me.

Hello,
and the rest of story??
i can flash TWRP in download mode, and i can intall zip by TWRP , the lineage rom,
but, cant odin flash official md5 file, it stucks on logo.
So I've bricked my phone. And I can't make it work. Yesterday I finally had some time to thinker with the phone and decided to install Fulmics Rom 6.0. I had already downloaded it a while ago but first now had the time to install it. I made a post in the Fulmic's thread but with their new 6.5 fulmics just out, so my post got berried so quickly so I got no replies.
I started in TWRP with doing a backup, then a wipe and then started the install.
It seemed install was going fine, I even got the Fulmic's GUI midways and selected appropriate model, D855. I tried to keep things as vanilla as possible and chose to not uninstall anything and keep stock temperature throttle back.
But when the install completed I got one error: set_metadata_recursive: some changes failed
Phone wouldn't boot. I had however made a backup before I started and I was able to restore from backup from within TWRP.
Then phone booted and it seemed all was fine. But as I had my mind set on the Fulmics ROM I had one more go, just ti be sure I didn't mess up and chose something bad in the Fulmic install GUI. Also I did a wipe first, then I wiped the cache/dalvik as I once read that could make install easier. And result same as before. set_metadata_recursive: some changes failed.
Tried to reboot but I get flash screen with LG loge and powered by android on the bottom, and then when screen changes to only LG logo it gets stuck'd. No matter how long I wait, and I tried to wait for hours remembering wiping dalvik/cache makes boot take longer time. Stucked on the boot load. Notification light changes from green to blue. And the Lg logo is there.
Worst part is that now I can't even restore it to my backup from yesterday.
Here is my phone:
Lg G3 D855 16 GB 2 GB RAM
Android 6.0 stock LG update.
TWRP 3
Rooted
For now I would settle for a working phone. That is my main priority. Truth be told I got scared now and I don't know if I will take my chances putting a custom ROM onto the phone. After all my android 6 was working nicely, phone was rooted and adaway was working nicely. I guess I got greedy and wanted more
It would be very nice if people could take things very basic, like if I am to do certain things in TWRP don't assume I will understand unless you go into details. Been struggling for hours upon hours now and my mind is mush and concentration was lost a few hours ago. Yet I need to keep at it as I can't be without a working phone tomorrow. For instance in the TWRP under tab advanced > sideload what can I try there to make phone boot?
If I have left out any important for you to help pls just ask and I will reply as fast as possible. Any and all tips and pointers will be much obliged.

Downgrade to twrp 2.8 and flash again hope you are good too to go....
For me , if i have problem.
Replace sdcard , format data on twrp and flash .kdz (not after 30x.0426.kdz) , usually LGup can made download mode it self.
If can booting , make temporary root and get twrp.
Ok I had TWRP v2.8.7.0 laying around. I've used it before with success, so I know it works with my Lg G3.
But still not possible to boot.
I will try to read up on the .kdz as I never even heard of that before. Maybe if I am lucky that will save the day.
Hehe what do you know. TWRP v2.8.7.0 worked!
I dismissed it too fast, turned out it didn't get stuck'd on boot, boot just took a while because I had wiped everything.
Now I can see android is upgrading apps, and also when I think back to the first reboot with twrp v2.8 it was fulmics logo on the bottom part of the screen not android I guess my mind did not pay any attention as I was truly expecting to be stuck in boot loop this time too
Fingers crossed it is working now, I guess I didn't pay much attention when I tested twrp v2.8 and pointed to the fulmics ROM 6.0 and it seems it will work whoha
Finally I've got a working phone, and I also got Fulmics 6.0 as I sat out to get.
Don't know what went wrong or what caused the boot loop, but twrp v2.8 seemed to be the working solution.
IT seems everything works except I lost root. Which is fine for now, I will root another day.
Now I just need to use the dang phone
Deleted for your own safety
Btw, as the phone must be rooted to install custom ROM's it does seems strange that phone after installing Fulmics 6.0 appears to NOT have root, according to RootChecker. Could it be that the custom ROM is confusing RootChecker or did root somehow get revoked?
Is there a manual way I can check to see if phone is rooted? Cos there is, terminal
I took the chance tp get the latest KingRoot v4.9.6 over my previous v4.5.6. And run the APK.
Seems there must have been some issues with SuperSU, I had v2.54 and BETA v2.65. None of them kept root after install.
Found the latest stable that was superSU v2.78 and that fixed my issues.
TWRP ver 3.x messed my phone up too. Thought I had a good EFS backup, but when I needed to restore it, it didn't work. I will not be using ver 3.x again for a long time. Ended up losing my IMEI because of it.
