SM-T700- Encryption Persists after flash. Can't get to ROM. - Galaxy Tab S Q&A, Help & Troubleshooting

Here we go. I had CM12 installed on my SM-T700 with encryption enabled. I wanted to revert back to the stock ROM, so I flashed via Odin. When it booted up it prompted me for my encryption password, but it is not working.
It seems that the encrypted disk persisted re-flash and it's not letting me boot into my os. Any help?
Edit: It seems the flash reverted my recovery to the stock sammy recovery.

Factory reset then flash original firmware via odin.

[Q] Phone still encrypted after odin, stuck in bootloop

Hi all,
I have a soft-bricked GS3 that I can't revive even after using odin 3.09. Hope you guys can help.
My encrypted phone was running CM10.1.3 and I decided to update it to CM10.2 using sideload. That didn't go well and I was stuck with the CM bootloop.
So after several tries with sideloading I decided to use odin to turn it back to stock. I tried both the stock LG1 and LK3 and both went thru the flash without issues but after the phone reboots it asks for the encrypted storage password. After the password entry it's stuck at the samsung logo bootloop. (p.s. LG1 recognized my encryption p/w but LK3 didn't)
I had flashed using odin on an encrypted phone before and I don't think the encryption stays after the odin flash. Am I missing something like flashing the bootloader together with the .tar file? I tried searching and google but can't seem to find an answer.
Any suggestions? Thanks!!!

Can you try booting into recovery and doing a hard wipe/factory reset? If you flashed a stock *.tar file via Odin, it should deliver a complete stock system with all partitions updated. There shouldn't be need to flash a bootloader separately.

Got it. Thanks!! I kept thinking that I couldn't use the recovery because CWM does not see the encrypted partition and therefore cannot do a hard wipe. I totally forgot that after odin I was back to stock recovery and therefore could do the wipe. Thanks again!!

TWRP help on Beta8

After clean flashing Beta8 my twrp always asks for a password but it's always wrong.
I've wiped the whole of the internal storage, flashed stock OP3 recovery and then TWRP again.
Everytime I get the dm-verity error when my phone boots up (this only went away when I flashed 3.2.6 and then stock recovery however)
Any ideas how to fix this? (3.0.2-1.28)

Help flashing back to stock, tried everything.

Hi, i'm having trouble flashing back to stock.
I've got the latest stock firmware from sammobile.
Using twrp to install it says missing META-INF as the firmware zip isn't made the same as custom firmware.
Adding the tar.md5 to ap in odin flashes the boot and recovery but goes extremely slow when it starts flashing system (left it 2 hours and it hadn't even got half way) I'm guessing that's not normal.
I took a backup with twrp before I started flashing in twrp which flashes fine but I get endless boot loop when trying to start it.
I've tried fastboot but it doesn't detect the tablet.
I've tried different usb ports, cables, different versions of odin and different stock firmware. I'm ready to throw it out the window.
One thing to note is the [P600][Touchwiz] Marshmallow Rom 20170622 works great but also boot loops when I turn it off and on again, I have to boot into twrp then choose reboot in there and then it boots ok, that doesn't work with my twrp backup though.
Anything I'm doing wrong?
Thanks.
Well for some reason after installing marshmallow rom again then installing my backup it boots fine, havn't a clue why it failed to boot the other 4 times.
Nope
Back to continuous boot loop after second reboot.
All I did was turned developer options off and it's boot looping again.
Flashed original stock boot.tar.md5 and recovery.tar.md5 then factory reset and wiped cache but still boot loops.
Is it because I flashed a Marshmallow custom rom so it so you can't downgrade to a lolipop rom even though it's stock? Boot loader changed? Kernel?

I'm not quite sure what your problem is but you should be able to downgrade, I've done it before.
Try this guide first. I've had success with it.
If all goes well you can then try to flash your stock ROM. The one I've flashed successfully in the past is the one in this post.
Good luck!
You may need to repartition your system. Tick the repartition in Odin. **All data will be lost**

Thanks, I followed the guide in that post and it flashed ok then I finally managed to flash the latest stock!

TWRP asking for a password to decrypt data

Hi,
I downgraded my Nexus 5X from stock 8.1 (OTA) to the latest stock 6.0.1 firmware (via fastboot), and booted up to make sure it's working. All is fine. Device is wiped to a factory state.
I then flashed the latest TWRP recovery, and then rebooted to recovery to try and flash Magisk. At this stage, TWRP asks me for a password to decrypt data, and I didn't set any password at all. If I click on Cancel to continue, I'm able to see the zip file that I placed in /sdcard, presumably coz it's encrypted and TWRP can't read it? What's the password though?
I notice upon Android bootup, under Settings->Security, that my phone is encrypted. I tried factory resetting the phone to disable encryption, but it shows up encrypted even after factory reset.
Also noticed that when I try to reboot, it always reboots back to TWRP rather than Android. Once I flash it back to the stock recovery, then I can boot to Android.
How can I get TWRP to work on an encrypted phone without a password?
I had a similar issue with 8.1. I reset my phone, waited booting and setup is done, then I tried different versions of TWRP and finally no password required!
Which version of TWRP worked for you?
I ended up using 3.0.2-2, which was released around the same time as the 6.0.1 image that my N5X is running on. Formatted data and wiped everything but system in TWRP, rebooted to TWRP, and it worked after that. Weird how fastboot format userdata didn't work.
