Can't ROOT, Stuck in Download mode - Galaxy Tab S2 Q&A, Help & Troubleshooting

Hi, I have a T810 and I wanted to root it. I am on the OJ1 bootloader.
I flashed the kernel for 5.1.1, the permissive kernel.
It works perfectly, but of course no root because I needed to flash the autoroot for T810 for 5.1.1.
I flash it successfully and it goes into recovery mode than all the writing for the root comes on.
It does all that correctly but it reboots and goes into download mode. I try to force boot by holding all keys.
It goes onto the Samsung logo for 1 second and then it goes back into download mode.
I have reflashed stock rom and I have tried 20 times and still it does not get out of download mode.
What am I doing wrong??

Looks like nothing... try rooting with supersu zip using TWRP

[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.

Odin flash twrp boot loop

I followed the steps in this guide attempting to flash a rom. https://forum.xda-developers.com/tm...lopment/rom-stock-debloated-deodexed-t3423387
I was able to flash the BL and modem no problem. I proceeded to flash twrp and have been stuck at boot since. I can only go back into DL mode. Read a few places that said to reinstall rom. How do i go about installing a rom via odin? Any help is greatly appreciated.

Okay. Here's what you do...
First, boot to DOWNLOAD MODE. Once in Download Mode, press the keys again like you are booting to Download Mode (VOLUME DOWN + HOME + POWER)
Watch the screen while holding the keys. When the screen goes blank, switch to the key combination for booting RECOVERY (VOLUME UP + HOME + POWER) and hold them until the TWRP screen appears. If the TWRP screen does not appear then we know TWRP didn't stick when you flashed it via Odin.
If the TWRP screen appears, release the keys and let it continue to boot to TWRP.
If TWRP does not boot, then I'd suggest flashing the stock firmware for your device. You can download the stock firmware for your device from www.sammobile.com or from www.updato.com
Sammobile.com is a very slow download unless you pay for a premium account. Updato is much faster. Make sure to select the correct region for your device before downloading the firmware.
Which version of Odin are you using? I've been using 3.12.3 and haven't had any problems at all with this version.
Once you habe downloaded the stock firmware, open Odin. Boot your device to Download Mode and then connect your USB cable. Make sure Odin shows you are connected.
Next, click the OPTIONS TAB in Odin and un-check
AUTO REBOOT. Then, select the AP TAB in Odin and navigate to the firmware file you have downloaded. Let Odin do its thing to verify the file and click START to begin the flash. Once the flash is complete, disconnect the USB Cable and press the key combination for booting to Download Mode again. Once the screen goes black, switch to the key combination for booting RECOVERY. Once in recovery you can select the reboot option to boot your device normally and start fresh from there and attempt to flash TWRP again.
Also, which Note 5 do you have?

Hey, thanks for your response. So I was able to get my System back to working. I had to downoad the stock firmware through sammobile. I ended up paying for the fast download (30days of service) Well ill keep updato in mind if this every happens again. Im on N920TUVU4EQE1 For the n920T since i had already flashed the modem and bootloader before i flashed twrp. I'm on Odin 3.12.3 as well.
"This device uses dm-verity!
This means that swiping to allow system modifications will prevent you from being able to boot if you are using the stock kernel. In order to bypass dm-verity's boot prevention, you will have to install a kernel that has dm-verity disabled in the fstab."
Apparently the kernel i was using wasnt allowing twrp to install. So now i have to figure out how to root my new stock firmware and install recover so i can flash a rom.

What you have to do is this...
Flash TWRP, swipe to allow system modifications and then flash the no_verity_opt_encrypt_5.1.zip available from
https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
This zip will disable dm-verity and forced encryption in the fstab and allow you to boot normally.
Once this had been done you can flash the root zip of your choice and go to town with debloating, custom ROM's and custom kernels.

When i flashed TWRP i unchecked the Auto-Reboot option. did a key combo to get to twrp but it didnt ask me to swipe to allow system modification. So i went ahead and flashed no_verity_opt_encrypt_5.1.zip with success. Proceeded to flash SuperSU-v2.66 and it got stuck at -Creating paths. I rebooted to recovery and found this guide https://forum.xda-developers.com/galaxy-s6/general/root-s6-nougat-supersu-t3570740
Coming from sickmade 6.0.1 and through all the struggles i am now at stock ROOTED firmware EQG3 andriod 7.0! I just had to take my time and search around a bit. You guys are all amazing. Hopefully if someone has this problem they will find this thread.

Glad it's working for you. Good job. Now you can make your Note 5 your own. I'm an S6 Edge Plus user. We use the exact same ROM as the Note 5. We just use a different kernel. Happy flashing. If you run into any issues don't hesitate to ask me or anyone else here at XDA. This is a great place to read and learn especially with your Note 5. If a problem has occurred before you can bet that someone has posted about it and you will find a solution.
the phone initially booted up normally. and i power off try to enter recovery mode but i got bootloop , is there any way to get into odin mode , recovery mode is broken ( i flashed recovery with odin it took 15 minutes so i click stop and it crashed ) my phone is sm m20

[D290] Flashable Stock Rom (Try this if DL Mode isn't working)

If the phone ever stops booting to DL Mode, but still enters TWRP or boots to the normal android OS.
Try flashing this zip. It might freeze TWRP after it ends flashing.
Then after the flash, flash a KDZ.

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.

Question HELP : Boot Loop and can't enter recovery / download

Hi All...
i unlocked my Samsung A8 2021 bootloader, patched the AP file with magisk and flashed it with odin.
i am now in bootloop without any way to go into recovery or download mode.
tried all buttons combinations with pluging ang nnpuging the device.
i now sww posts regarding pathing only the boot.img and the entire AP file but the damage has been done...
anything i can do to make my device working again?
thank you!
ok i managed to enter download and went back to stock with odin.
what did i miss?
should i now patch only the boot.img in magisk and do it again?
will that work?
thanks
Hey @tlccksww , how did you get back into Download Mode? I botched my update with Odin and can't get Download Mode to launch. I can get to the recovery, can also run ADB commands, but can't get back into the bootloader.
