SM-T813 On Loop Can Only Load to Bootloader - Galaxy Tab S2 Q&A, Help & Troubleshooting

I have a SM-T813 that I installed TWRP. I backed up the stock rom before loading Lineage OS. I wanted to reload the stock ROM, which I did through TWRP. After the reload the device is stuck at the Samsung graphic and "Android is starting...." screen. I tried reflashing TWRP via ODIN which did not work. I reflashed stock firmware via ODIN and that also did not work. I can only boot to Bootloader and using ADB to try and get into recovery says no devices are connected.
Cannot power off either.
Any suggestions?
THanks!

Fixed it. I ended up loading a different ROM which kicked it out of the bootloop and let me get into the Recovery. Cleaned things up and reloaded the factory ROM. All is well now.

XT1095 Only able to boot into bootloader or TWRP recovery

Whenever my recovery is TWRP I am not able to boot into any type of ROM. Every time I reboot my phone it will be past the "your bootloader is unlock" and always boots straight into TWRP. When I flash stock recovery I am stuck at a image of a Android and it just stays at "erasing..." till it reboots itself. I have attempted to flash different types of roms by sideloading through TWRP and also attempted to flash stock recovery through fastboot with no luck at all.
The issue started whenever I was on stock 6.0 and flashed TWRP. Once I was in TWRP at the end when I was rebooting my phone I said yes to install supersu, which I know now was a mistake. Afterwards I was stuck in a bootloop were I finally attempted to do a factory reset which seemed to have made things worse. That was when I was stuck at the "erasing..." whenever I attempted to boot through stock recovery. Not sure what else to try at this point.
Any help would be great at this point.
I'm in the same boat. Exact same problem with no idea how to fix. I can get into fastboot screen, but that's it. Suggestions? Thanks in advance.

[SOLVED]Recovery won't boot, and phone boots recovery automatically.

Hello all!
Having a difficult issue with my phone. I downloaded and flashed SpaceX-Kernel_MM_RC1_G920F_Test.tar.md5 along with using SuperSu 2.65.apk to root my phone in stock.
Everything went fine, and I installed TWRP Manager to flash the latest TWRP. The flash and verify failed, and it tells me I either already have it installed or something is wrong. Reboot into recovery?
I rebooted my phone, and the screen is stuck with "RECOVERY IS NOT SEANDROID ENFORCING" with the Samsung Logo. Now I can power down and go back into download mode, but I can not flash Twrp via odin, even when it passes the phone is stuck on the recovery screen. I can't restart my phone to boot normally either.
Any suggestions? Thanks in advance.
Edit:
I downloaded the stock firmware from sammobile, and flashed it via Odin 3.10.7. At first it was freezing Odin, after a few tries I closed all my programs and restarted my computer. I reopened Odin with Admin privileges, and flashed again. This time it worked! I guess I will try flashing twrp again.

Stuck in recovery after 4.0.1 OTA

Hi,
I was running Oxygen 4.0.0 and a beta build of TWRP 3.0.3 which works with new encryption. I used the android update mechanics to get the 4.0.1 OTA. System rebooted to recovery, recovery threw an error (zip file corrputed) and since then I am not able to boot the system. Whatever I do I land in TWRP recovery.
Things I did so far:
- Tried installing the full 4.0.1 zip. Install worked without errors, device still boots to recovery.
- Tried to get stock recovery, since another post (https://forum.xda-developers.com/oneplus-3t/help/stuck-recovery-mode-t3532524) indicates stock recovery might fix the problem
--> stock recovery is not obtainable anymore. Seems deleted from all the download links I could find. Example is here: https://forum.xda-developers.com/oneplus-3t/how-to/zip-flashable-firmware-modem-t3509015
- Wipe cache and dalvik cache in the hopes, the instruction to boot to recovery is there somewhere.
I did not do the unbrick tool, since I run linux and didnt want to fiddle with windows yet.
I did make a nandroid backup, so once my system boots again I should be fine.
Any Idea where to either get a mirror of stock recovery or how to fix this problem otherwise?
I had this same problem, and I solved downloading the unbrick tool and extracting the recovery from there. Here is the file

Also locking the bootloader worked for me. Booted into system then unlocked again.
Thanks a lot for the stock recovery. That worked!
Once it booted, installing TWRP and SuperSU again.

Does your TWRP boot correctly? I flashed it and when I restarted I still had the stock recovery, so I used fastboot boot and it booted, but it is stuck in the loading screen.
Edit: After rebooting and reflashing totally random, it worked.

Yeah, worked totally normal as it should.
My educated guess about this whole dilemma is, the system sets a flag to boot to recovery which TWRP doesn't clear and only stock recovery clears. Usually those flags should be in cache partition, but in this case isn't.
Tldr: don't use build in update mechanisms if you modified Rom and recovery.

Can't access Recovery after updating TWRP

After flashing the latest TWRP 3.3.1 image file from TWRP 3.2.3 and upon reboot I got an error "Could not do normal boot" and it took me to ODIN mode. Thinking maybe it was a corrupt file I flashed the .tar file from Odin and it successfully completed and rebooted into the system. Okay great. So I tried to boot into recovery from the system and it took me back to the same error. Tried several times to flash recovery from Odin and each time it completes successfully, boots into the system. Everything looks great and works - until I try to boot into recovery. Tried powering down completely and giving it a few minutes but the same thing happens when I power up. the only way I can get back into the system is to flash the TWRP tar file again from Odin and let it boot the system upon finishing.
I have searched the forums and the web without finding any solution that doesn't include going back completely to stock. In those cases the system was corrupted as well. Not really wanting to do that since everything works except booting to recovery. Any suggestions?
Update - I was finally able to download XAR-T813XXS2BSJ3_T813XAR2BSA2-20191016 and install it so I currently have the latest stock I can find for my T813. I have not tried to install TWRP yet on this version. I am a little leery to do so at this point since I've had no luck on any previous attempt.
Well, SSDD! No matter what version TWRP I flash, when I try to boot into recovery I get "Recovery Booting....Could not do normal boot" and it takes me to download mode (Odin Mode). I give up. I guess I am doomed to using a stock tablet and all of my previous apps and set up is no longer accessible. If by some miracle somebody has a fix I'm all ears.
Update - Finally was able to root with CF-Auto-Root through Odin. While it is not my root method of choice it is the only way I can root since TWRP will not load for me. At least I can get to my TB backups and restore most of my apps. Also, I can get rid of the bloat that pure stock sticks on the tablet. If I hadn't just bought a new laptop, I would seriously consider replacing this tablet.

Recovery Bootloop

So I successfully unlocked my bootloader and flashed custom ROM and recovery, first boot it was okay, I was able to setup Android and installed apps, now when I rebooted it, it only boots to recovery. Phone can still be detected by my PC, can also get detected in fastboot when in bootloader. So I think there's really a workaround for this I just didn't know how and I am now hesitant to follow web tutorials if it isn't an official forum just like this.
Things I already did:
Reinstall ROM
Reflashed custom recovery
Cleared Data/Dalvik/Cache
Factory Reset
Flash the stock firmware by SP Flash Tool, it'll help to revert back to stock and stop boot loop!
