New ROM Encryption bootloop

[unnecessary background information] A while back I decided to encrypt my OnePlus 2 - mostly to compare its performance with my Nexus 6P, which is also (obviously) encrypted. Today I decided I was tired of Oxygen OS and wanted to install CM13 since Grarak had gotten the fingerprint scanner working properly. I went ahead and unlocked the bootloader, installed TWRP 3.0.0.2, and excitedly flashed the shiny new OS (without making a backup, like an idiot)[/]
After booting up into CM13 the system asks me for my encryption key (sure, whatever) and then I get this big screen that says "Decryption Unsuccessful....The password that you entered is correct but unfortunately your data is corrupt" and goes on to say that a factory reset will fix the problem and any lost data can be re-downloaded from the cloud. I said "great!" and hit the "reboot now" button that reboots back into TWRP, runs a short script, and sends me back to where I started (presumably not on purpose).
Now, I tried doing a full wipe of the entire device via TWRP, which sent me into a new panic mode when I couldn't manage to get any files to transfer over when I tried to send them over MTP - I finally went about using the ADB Sideload feature in TWRP to once again install the same (and a different) ROM all of which garnered the same result.
Finally, the point of the story: Is there a way for me to fully remove encryption from the system from within TWRP? If not, am I totally hosed or does someone have another idea? Frankly, I'd be happy to just have a booting phone at this point.
Thanks in advance!!

So following up on my own thread, I found the setting in TWRP that specifically allows you to erase the data partition (something that I thought I had done when I did a standard wipe and/or when I did the advanced wipe and specifically told it to wipe everything) and rebooted and it finally booted happily into Android. I'm not sure if this is a bug in TWRP or a bug in CM's script that is causing issues but something isn't quite right.

Cannot wipe with TWRP

Hi,
I have G935F, installed TWRP 3.0.0.0 and rooted, WITHOUT wiping. System boots correctly, but I cannot do factory reset or wipe with TWRP, because I got some messages like "Cannot mount Data" and "Failed crypto loader". I understand that it has to do with encryption. Can someone please enlight me, and give me tips about the issue?
Thank you

You have to download dm-verity and force encryption disabler from here , put it to SD card, reboot into TWRP, FORMAT DATA (not wipe) and flash that file (dm-verity and force encryption disabler). All your data will be erased.
No way to unencrypt without loosing you data for the moment(

"All your data will be erased" means that after boot I'll find a clean system installation (as factory reset)?
I hope not to be posing stupid questions, I'm completely new to this world
Thank you very much

Yes just as a factory reset

No, you cannot perform a backup, because your data is encrypted by default and the only way to disable it is to format your data.

I have a unique problem. I have a HTC Desire 612 from Verizon and I decided to revive it to playe PoGo. But it was stuck in a boot loop and I couldn't get any custom ROM.
Finally a gentle soul here gave me the stock rom and I flashed it vide TWRP and played PoGo for weeks. Then yesterday the phone bro led and when it came up it was stuck in a boot loop.
So I decided to flash the stock ROM again. But before that I tried to factory reset. I could go to TWRP, select wipe data, enter yes and the wiping was successful, then clear dalvic and cache and system beforehand finally I flashed the stock ROM.
Surprise surprise is NOTHING happens. The phone boots without the apps telling me they are installing. Then I get back the exact same data in my phone including my selected wallpaper and apps. Before I can do anything the phone restarts.
Point is wiping and restoring the stock ROM does NOTHING to the phone yet the processes are successful. Can somebody help?

Similar situation here. I run on my spice uno on stock Android with all security updates. Recently my device entered into boot loop when I restarted it.
Things I tried -
1. Wipe cache, restart
2. Factory reset, restart
I did these steps by entering into recovery mode with both sims and memory card attached.
Then I removed everything and again tried above steps.
At last I also tried, mount system, wipe cache, factory reset, restart (in sequence)
I don't want to root my device and loose ota updates.
Please suggest a way out.
Thanks in advance

[Q] Rooting Android Nougat on SM-G935F

Hey guys,
I've recently decided to try and root my device again (I had rooted Marshmallow previously, but went back to stock). Problem is: it won't work.
Here's what I tried so far:
1) Chainfire Autoroot (latest version for Nougat): device won't boot. It's stuck at the Samsung logo fading in and out. I let it sit for about 20 minutes, without any changes.
2) TWRP with Magisk v12 and samsung-antiroot-removal 2.4: it performs the process but says it couldn't mount /data. After reboot -> the same Samsung logo issue as with 1.
3) TWRP with no-verity-opt-encrypt 5.1 and SR3-SuperSU v2.79. Very same as with 2. I should note that I didn't wipe my device though.
Does anybody have an idea what's actually going on there? I would really like to root my device again. Preferrably without losing any data on it.
Cheers and thanks in advance,
Mark

Unfortunately the problem is without wiping data, the rooting process does not properly.
Rooting has to modify some files both in the boot loader and kernel. Some of your apps also have modified the boot loader for the apps to start properly.
when you try to root it causes a conflict with the existing modifications caused by the apps leading to a boot loop.
That is why it recommended you sync your phone prior to rooting, wipe data so that you have a clean boot image, root and then restore your app back up.
magisk v 13 has automated the rooting process during installation, it seems to work I done it several times already after updating my rom but I also clear data first.

Thank you. So it seems I will have to bite the bullet, wipe all data and start from scratch (more or less). Unfortunately every good backup solution requires root access. :/ But as far as I remember the Google Drive backup should work pretty well in regards to apps and their respective settings. *fingers crossed*

Xiaomi Redmi Pro stuck on Mi logo - Xiaomi EU ROM

Xiaomi EU Booting problems
Hi Guys!
I'm using Xiaomi EU ROMs for some time and I must say that they are brilliant in terms of being ROW form for our phone which is as You know China only.
However I have recently an issue with phone stuck on a Mi logo while booting. After shutting donw the phone to start it I have to clear Dalvik every time in TWRP which makes it boot in ~10 min.
I have:
1) TWRP 3.2.1 (the newest I've found for Omega), - but the problem also appeared on 3.0.3 (Hanuma) and 3.1.1;
2) Tested clean install (wipe Dalvik, Cache, System, Data) - it works but only up to the point when I install my every day apps. After that the problem re-appears;
I'm not using Magisk or any type of rooting (because I do not need it).
I've tried upgrading (form 8.3.29 to 8.4.19 and 8.4.26 ROM) and clean install. I've tried to fix permissions, and repair filesystem (to data and system partition) in TWRP. I've tried even rebooting without dm-verity via console in TWRP (which shouldn't be an issue as it is fixed in Xiaomi EU Roms). The problem always seem to be in Dalvik partition (because after cleaning it the Phone boots.
Do You have any suggestions what to do to fix this issue? Please help!
Thank You in advance!

Thank You for Your help. I've managed to solve my problem, which must have been in the Xiaomi account verification. Everything seemed to be ok but it was not. When I was cleaning partitions via TWRP the error was still comming back. When I did factory reset and removal of Xiaomi account from the phone everything went back to normal.
Best regards,
H.
