I'm having a very strange issue with my device right now. Basically whenever I flash any custom ROM I end up in a boot loop. It started last night after I flashed a couple of CM10 based ROMs and then tried to revert back to Skynote which is touchwiz based. I was able to fix it by using Odin and flashing the stock Rogers ROM .tar file. That fixed everything and stock was running fine all night with no reboots or issues. This morning I did a fresh download of the ROM rebooted to TWRP wiped cache *2, Formatted system *2 and factory reset *2, installed the ROM and rebooted. I should mention I am using TWRP version 2.4.1.0. The ROM usually loads for about 1-2 mins then reboots and repeats over and over. Does anyone have any ideas? I've even formatted the internal and external storage. I did notice there is one folder on my internal SD card that I cannot seem to remove called Z and has a LMT.apk and another folder with wallpapers in it. I cannot delete or remove this folder as it keeps saying the folder is write protected. Even after formatting the internal storage that folder remains which makes me wonder if my SD card is screwed up.
Sorry for the long post but I am running out of ideas and don't want to be stuck on Stock. What could be causing this? I've tried flashing a new kernel from TWRP and still the same results, I've even tried different ROMs just in case but still the same results. The only thing that seemed to work so far was the stock ROM via Odin.

I should probably add that I was coming from Android 4.2.2 and want to get back on 4.1.2

Do you have SD Card adapter for the computer? If so, try removing the card from the phone, then plug it into the computer and formatting it that way. For the ROM boot loop issue, try flashing a stock ROM using ODIN, then using whatever method you like the most to flash the ROM you want to use.

I'm now pretty certain its a bootloader issue as I'm downgrading from Android 4.2.2 to 4.2.1 but thanks.
take your external sd card out and see what happens

I wiped everythign 2x and then I flashed the file you posted in the other thread and removed my SD card but still getting reboots. Should my SD card be called sdcard0 still in my files?
yes, your card will still be called sdcard0
take your external card out completely, and see if the phone still boot loops

It still loops. This is crazy, when I used Odin to go back to stock it was working ok but everythin else has made it bootloop. I can try using Odin again when I get home and see if the restore SD card file works then. Does anything have to be done to the bootloader?
no, don't mess with the bootloader; you will probably brick it if you do
go back to stock via odin for a day or 2, and make sure its not the hardware itself..

So its not like moving back to ICS from jellybean where you had to flash a new bootloader?
Op you're on Rogers right? Make sure that you have the Skynote without the new modem.

I don't think I have flashed a new bootloader more than once in the last 6 or7 years, on an htc evo4g..
you should not ever have to do that on this phone

Same here
I am having the same exact problem you are veeboom. It's not boot-looping because it actually lets me into the phone for about one minute; then it reboots. I have tried everything that you have tried, right along with you and result is nil. It won't stay on for more than a minute. The only difference is that I am just trying to get Roger's Clean Stock ROM working. It sounds like you have accomplished that and are trying to get a custom going. I have tried Odin flashing 3 times; once without the sd card. I am pretty sure SD card is not the issue. I have wiped this phone at least 5 times (everything except the the extSdCard (AKA sdcard1).
I am going to see if I can find some other posts on this problem and will let you know if I finally find a fix. Hope you will do the same.
Happy to report the end of the boot loop!
Although I'm kind of embarrassed to admit it was caused by an incompatible modem file I flashed over and over... :silly:
Thanks for everyone's help.

Things just got worse
I have have the phone for about two months. A week ago I rooted it with Samsung Note II tool box and everything was fine, until I found out that there were these "custom ROMs" available. So I flash one, but it was unstable. I flashed liquid smooth; same thing, then I tried a few ROMS that were a little more mature, but their were always things I could not live with (like no blue tooth or apps crashing). I also found out what a boot loop was all about. It sucked, but the forums help me get it fixed. Now I am tried of messing with all these custom ROMs and I just want my old reliable system back, with root. Currently I am trying to get Roger's CleanROM AT&T Special Edition 1.2 working again (with I believe I started with). I have been unable to remedy boot loops that happen about every minute. I have flashed, wiped (everything), unrooted, re-rooted, flashed with Odin, flashed core kernel via odin per instructions, called it bad names and threatened it; then said I was sorry. I have repeated all these things many times, including with and without the extSdCard. SD card does not seem to be the issue. I am still looking for more things to try. Just now it has started refusing to boot at all. I gets to the boot screen and gets stuck.
I am trying to find out more about how to use ADB to re-partition upon stock ROM flash. You know anything about that? I have been at this all day.
It sounds like you may have done the same thing I did which was flash an incompatible modem file. My suggestion would be for you to use Odin and flash back to the Rogers Stock ROM. It's easy and takes less than 10 minutes.
Basic instructions,
1. Download and unzip Odin
2. Put your phone in download mode (turn off your phone, and press the buttons together: vol down + home + power for a few seconds)
3. Run Odin then hit PDA button on the right side, then find and choose the firmware file you downloaded to be flashed.
4. Make sure your device is recognized in Odin3 (The ID: COM box near the top left part of the Odin program should go yellow once you connect your phone)
5. Make sure re-partition in NOT checked
6.Press Start to initiate flashing
7. Once finished your device should automatically reboot. You may need/want to do a factory reset which will wipe all your data and you would be back to the way your first got your phone. Enter into recovery mode by turning off your phone and next press the three buttons simultaneously: volume up + home + power. After getting into recovery, select Wipe/Factory reset.
8. Reboot
You are now stock 100%

Hi there
FIrst of all sorry for the way i'm talking but well im a foreigner and sometimes make mistakes.
To the point. My Note 2 had Ditto DN4 flashed, it was working fine BUT today it just decided not to. It kept rebooting after 4 sec every time so i decided to reflash rom, i did it aaand still the same problem. Ok then, i grabbed this '3 files ROM with PIT file', sorry but i don't know the proper name. Either way, i tried to flash it using odin and thats when things started to go crazy. For some reasons it did not flashed and i was left with just DOWNLOAD MODE! I have no idea why but odin kept saying FAILED after NAND WRITE line. I panicked, flashed it like 45416165415 times but still did not work. After i read a few threads i thought, that i bricked the device BUT i thought what the hell, I'll flash recovery again aaand IT WORKED!
So now, what I'm asking for. Can anyone tell me what are the steps now? What ROM should i flash, if i had MJ5 bootloader? (well i think so, in Ditto thread they say that it works only on MJ5 but i don't really remember whether i did flash it or not). I'll be really really gratefull for any help. I just don't want to ruin it after that recovery flashed.
Unbelievable things happens frequently when using a custom rom or kernel ，especially on the device like N7105.......My pac-ROM got crashed when converting an app to system folder with Ti-backup and reboot，it blacked screen after the first logo screen， and failed enter recovery despite I pulled out battery. When I got crazy and was about to work it out with odin and it entered rec.....I think maybe the single tar.md5 file will help the most......If you a lucky enough
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..

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..

Hey All!
I have this very interesting problem with my SGH-T989D.
I have for years been installing customs ROMs unto my phone. The last ROM I used was CM11 20141201 Sultan Hercules, with the provided GApps. This was installed using CWM 6.0.4.3. I ran this for months with no issues. Earlier this week, I decided I would try something else. I rebooted and went into CWM recovery and did a few things first. I went and Fixed permissions, and formatted various partitions, and also did a factory reset/wipe of the device. Now when I fixed permissions the time it took seemed odd too me. Like almost a minute, and since then I have been having install issues like crazy. So, I basically ended up using ODIN 1.85 to flash a stock ROM I had from T-Mobile. Which seemed to work fine. When i was satisfied the phone was functioning properly, I then proceeded to install CWM 6.0.4.3 using ODIN. It flashed successfully, and it rebooted my device. However, it brought me to the ODIN emergency download window. where it tells you to plug in your phone to the pc and use KIES to recover to the device. Ok, fine I thought to myself, I'll try that. Now KIES doesn't recognize my device. It's definitely not a driver issue because it used to work fine before these problems. I am assuming it has something to do with the firmware counter on my device. Since it says it's at 6 now, even though it's an official ROM. I have also tried using Lorains thread to re-partition the internal memory using the his unmodified PIT file. But Odin crashes at the SET PARTITION screen when trying to flash it So, honestly I'm at a dead end as to what's going on with my device at the moment. Even when I try to flash an early stock version of a Telus ROM, it just keeps going back to emerg ODIN screen, even though ODIN flashes successfully.
Does anyone have any suggestions for me? If you require more information I will do my best to answer.
Thanks a million in advance.

I think you might have to re-partition your phone. Sultan's ROMs partition your phone a certain way and there is a fix for your phone somewhere on here to allow you to install regular types of custom roms.
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!

I'm running out of ideas!
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.
