Hi, I've been having some troubles with my brother's Galaxy Tab S2 (T813) I always root and
change ROMs with my Samsungs Devices and my brother asked me to flash Lineage OS in
his Tab, I proceded to do all the things:
-Backup
-Flash TWRP
-Format SD Card
-Flash the ROM
-Install Gapps
-Root via Magisk
Lineage Os booted correctly but later the tablet started overheating a lot and when we
connected to the carger it didn't charge anything (it said it was changing but after like 15
minutes it didn't go up not even 1%) so I decided to go back to stock, Flashed the original
ROM via ODIN everything passed but got stuck in the Samsung logo for more than 15
minutes, rebooted and again stuck in the boot logo so I tried to go back to recovery and
format everything again, but I had no battery decided to turn it OFF and charge for a while.
The Tablet started to overheat again while it was changing and it didn't charge a bit again!!!
Any ideas of what can be happening?? The tablet just went 1% of charge after 20 minutes
and I just turned it off because it was really hot.

Hello everyone,
I just hardbricked my SGS+ and now I'm a bit curious how this could happen.
This is what I did:
I used to run CM9 RC5 from arco68 along with the Kernel for ICS from Christopher83 and CWM 6.0.1.2.
Because my phone always lost the wifi-connection and also had some freezes I decided to try out CM10 Beta 3 from ivendor.
I backuped my phone, downloaded the zips and even verified the MD5sums. Next I flashed CWM 6.0.1.9 as recommended in the thread from ivendor.
After exporting the nandroid backup and other stuff like photos to my computer I wiped everything as mentioned in the thread, flashed the two zips and rebooted. Everything went fine and I was almost ready with setting up my phone again when I got my first softreboot.
Suddenly it showed the CM-bootlogo and after maybe 10 seconds I was back on my homescreen. I got another two or three softreboots until I decided to flash the Kernel 3.x from CastagnaIT.
I rebooted into recovery, wiped cache and dalvik cache, flashed the zip and rebooted.
Now I wanted to reboot into recovery again to fix permissions but instead I got a softreboot and my phone stuck at the CM10 bootlogo.
I waited for around 5 minutes and then I just turned the phone off and booted into the recovery mode.
Because I wanted a clean install without any problems like softreboots I decided to wipe my phone again (data, cache, system) and just reflash the zip for CM10. And at this point everything went wrong.
I flashed CM10 but when I tried to flash gapps my phone just turned off. And no, the battery was not empty. In fact the battery was at around 50-60% and my phone was also connected to my computer.
I tried to turn on my phone but now it stuck at the Samsung bootlogo.
The next thing I did was probably a horrible mistake. I tried to un-brick my phone but I did not realize that I could boot into download mode without problems so I guess my phone wasn't softbricked at all.
Well, after that I still stuck at the Samsung bootlogo and couldn't enter recovery mode. I got into download mode somehow and maybe this was my second mistake. I tried to flash the "i9001Reset.zip" via Odin. Everything went fine but when Odin said "Close serial port and wait until rebooting" my phone was completely dead. I think it was while I tried to flash the reset-file when I got a message like "MBR: read failed". So somehow I managed to destroy my master boot record.
Now I can't turn on my phone or enter download nor recovery mode. I already removed the battery for about 45 minutes but this didn't work either.
My phone is dead but at least I saved the important data and maybe I'll get a new one through warranty. Or I just buy a Nexus 4.
My questions are:
What did I do wrong especially when I tried to save my phone?
How can I prevent such things from happening?
And at which point I should have got help here in the forum or elsewhere?
I would really appreciate some tips for the future because I already flashed and used a lot of different ROMs but this is the first time something really went wrong.
Thanks for reading and thanks for your help in advance.
(Please excuse my non-perfect englisch.)

Problem started when my device ran out of battery. Now, plugging it using the original charger gets the device to a cycle of showing the battery icon (gray with electricity symbol) for two seconds and then disappearing; no loading battery animation nor percentages.
Plugging it to my laptop seems to charge it slowly, about 1% per 5-10 minutes. With this slow charging I was able to load enough juice to try to boot the device. This however only led me to a bootloop (up to the "Samsung Galaxy Tab S2" screen) until it dies again.
Worried and desperate I browsed through articles. Without reading as much as I did for when I was flashing my Xperias (this is my first Samsung that I tried to flash/mess with), I went on and did these procedures:
1. Downloaded Odin
2. Downloaded and flashed cf auto root (http://forum.xda-developers.com/tab-s2/development/root-cf-autoroot-tab-s2-sm-t3187202)
3. Downloaded and flashed twrp (http://forum.xda-developers.com/tab-s2/development/root-cf-autoroot-tab-s2-sm-t3187202)
These now added the following to my problems: a tripped knox counter, and a "recovery not seandroid enforcing" error at boot screen. Device still doing bootloops and is not charging using the original charger.
I went on and thought that maybe reinstalling the stock rom would solve everything. However this failed.
Would appreciate your assistance on this.
I think it's pretty obvious your charger is at fault here if it charges via USB.
Use a different charger.

I tried other/new chargers yet now it does not even tell me if it's charging or not. However it's plugged, it gets into a bootloop.
Flashing stock rom did not solve the issue. cant get into recovery either. I can only go to download mode.
Been stuck on this for 4 days now.
Please tell me if there are other methods I can try.
You have the same issue as someone else. They ended up sending to Samsung for repair.
If flashing stock firmware and factory reset can't fix it then it could be a hardware failure.

I actually got the tab going.
It seems that I was doing fine all along except that the tablet has almost no battery and all rebooting after flashing does not complete.
What I did was I charged the device while it's on download mode for more than two hours then reflashed stock rom. When it rebooted, it booted into two consecutive samsung screens (like normal) then the teal screen with android icon labelled "erasing". Then it proceeded to booting as if it was factory-reset.
However, the wifi is not working now. It is in eternal "turning on" mode.
If my current stock rom is T710ZSU2AOJ2_T710OZS2AOJ2_HOME.tar.md5, is there any other rom I can try?
Thank you
Well first things first, I was running a stock Tom lollipop 5.0.1 have a custom twrp 2.8.2 I believe, still have it been having it for a while tried 3.0.2 no difference so I switched back anyways I tried flashing stock rom all of them from T-Mobile starting with the original KitKat rom, I tried the stock 5.1.1 T-Mobile Canadian rom and it worked but it rebooted about every 3 minutes , so after trying many Roms also deleted everything off the phone first through teamwin recovery, I finally got a semi stable Tom which is resurrection remix I have 5.7.0 but had 5.6.9 anyways now it works almost perfect reboots maybe 3 times a day and thats with heavy use, by the way the annoying thing is when it attempts to reboot it gets stuck in the Samsung logo, I remove the battery and reinsert it and it boots like a champ, also if reboot trough os same thing happens, sometimes it won't turn on or take a charge unless I leaves the battery removed for a few minutes about 5. It's gets very annoying have tried so many things nothing seems to fix it and I have 3 batteries so if can't be that and original charger could it be a bad power supply ? I will upload pics in a sec one battery is worse than the other two holds no charge,. Stock rom would get stuck in the T-Mobile logo.

Dear all,
I have a Samsung Galaxy Tab S2 8.0 WIFI purchased last year (exactly to the day) in Cali. I believe it came with 5.1.1 XAR version.
A month later, my troubles began. I flashed with 6.0 Samsung WIFI ROM from some other country and the tab soon started to randomly turn off while being used. I am not sure if this is coincidental or not. When restarted, it would sometime fully boot, only to turn off while doing any mundane task surfing etc. and at other times, start and turn off as soon as the SAMSUNG logo comes. Weirdly, when I wait a day or two, it would start fully and work for a few minutes to half an hour
When I put it to charge, only rarely does the green battery logo came up, but most frequently I got a flashing thunderbolt sign.
I sent it to Samsung and it came back apparently with the correct firmware installed and the repair note said, faulty data cable replaced. But in a week of usage, the same problems started. I don't live in the US currently and so I don't have local warranty and don't have any means to send it back to Samsung USA. I've tried all remedies I could find, charging it to 100%, holding volume down and power for 15-30 seconds to simulate a battery reset, etc. to no avail. These days. it wouldn't even stay on long enough to access recovery mode, before turning off.
Yesterday, I installed Nougat 7.0 ROM from XAR on it and tried to start it. same problem. It says updating applications xx out of 26, and then turn off. When I try to access recovery, I got the android logo and when it gets to "Erasing", it would turn off. Then now that the warranty has expired, I installed TWRP (twrp_3.1.0-1_sm-t710_13317.tar) and this time I somehow goto to TWRP recovery mode, I just left it on there to see how long it would last, instead of immediately erasing the caches and restarting.
After that once, I couldn't get it to stay on long enough to access recovery. So I tried to go back to OEM ROM using Smart Switch, but to no avail once again. The Download mode still says Custom even after Smart Switch emergency recovery
I have tried flashing various other things (5.1.1 Samsung ROM, 6.0 ROM from UK with AP, BL and CSC files, TWRP 5.1.1 permissive ROM, TWRP), in various jumbled orde,r out of frustration. Nothing worked. here's a list of ROMs I've tried:
T710XXU2DQCL_T710UVS2DQC1_EON
SM-T710_1_20170406180713_vd28gnex7t_fac
SM-T710_1_20170330211239_qkurg70e9y
5.1.1_T710XXU1BOH7_T710XAR1BOH7_XAR
twrp_2.8.7.1_LL_5.1.1_t710
twrp_3.1.0-1_sm-t710_13317
t710_5.1.1_boot
Right now, the only thing I can access is Download mode and it says Current Binary: Custom, System Status: Custom, AP SWREV B:2 K:0 S:0 and worse than before, the tab turns off at the Powered by Android logo and when I plug it in, it doesn't charge but I get this boot loop (with the just the powered by android screen flashing)
would it help to re-partition and nand erase all and install a fresh ROM with a PIT file, if so can someone please share me their PIT file for this model??
I am out of ideas, and ready to break this expensive brick
appreciate any help,
thanks

Well i hve the same problem like you.. idk wht should i do with this condition.. bootloop.. always restart until logo.. :crying:
Please anyone help to solve our problem..
Your issue seems related to power. It seems your device doesn't charge correctly and is turning off due to running out of battery.
What does TWRP report as the charge state?
Do you get the same issue when the device is plugged in to the mains?

hi ashyx, I am pretty sure that battery isn't the issue here. even though the grey battery logo with a thunderbolt flashes while turned off and plugged in for charging, after a while it does charge anyhow. I can get it to 100%. Plugging in makes no difference.
I am thinking it could be a power button problem or a faulty usb port perhaps, if it is indeed a hardware fault?

Did you ever resolved this issue? Curious if you have a solution.
my galaxy note 4 (sm-n910t) caught in bootloop . i dont know what caused it. the phone simply restarts upto first bootscreen, ie upto 'samsung galaxy note 4' and then vibrates and then restarts.this process continues upto battery is down or i pull out battery.the phone is not entering to recovery mode but enters to download mode.
i have tried installing stock rom from sammobiles but it won't help.i have also installed custom recovery twrp but that also won't help to enter to recovery mode,
i am trapped pls help..
You didn't mention how you tried to install the stock ROM . Did you use Odin?
I just fixed mine with the same issue. I was able to boot into recovery and download mode but mostly download mode without bootloop when I had the usb cable plugged in. I used ADB when I could to boot into download mode, but the buttons worked too. Trying to restart the phone only lopped after the Google screen.
I followed several guides here to flash stock with Odin and wipe cache etc but none solved my boot loop issue. almost gave up but there is a video on You Tube that said the battery warping in the cause of the boot loop. The battery, after/during quick charge, may heat up and change shape causing the issue. Today I installed my new battery purchased on amazon and no more issues.
Now I am on stock and have to find a good rom.
If you do decide to flash back to stock there are a lot of good guides. You may find yourself stuck on the T-mobile screen for 15 minutes when booting for the first time but that is ok. If you still boot loop after installing stock and wiping cache I would try the battery.

hi OP,
did you find any solution to your problem?
Hello all. I'm also pasting this in the T-mobile thread in case it can be of benefit to someone. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.
