I am about to do a fresh install of marshmallow with root/TWRP.
My current installation has gotten bogged down over the last few months.
My question is, how do i format the data partition as unencrypted? My understanding is TWRP cannot format this partition, but I know no other tool capable.
Many have mentioned that unecrypted data partition will make twrp work better, what are the pros/cons? I am not concerned about data privacy.

Hi, no problem with TWRP you can format Data and remove encryption

Having trouble finding a firm answer on this. I have read that encryption has NO effect on Recovery mods since it only encrypts apps, data, and a few other pieces of info. (I thought that there was full disk encryption, but I guess not). So I would like to verify the following questions regarding the use of custom ROMs and Android encryption and I would like to do both, back them up, and maybe even change ROMs without issue.
I am fairly certain I can boot into a recovery mod (CWM or Twerp) without any problems while encrypted. Is this true? (I have seen conflicting answers here and on the interwebs).
If I back up a ROM and data (assuming this is done together in one backup), will I be able to recovery the backup properly and use it even when it was encrypted?
Thanks in advance.

You can boot into recovery and flash zips but you will not be able to access your /data partition since that's what's encrypted. For flashing ROMs this doesn't matter since those don't touch /data. However if you have to wipe your user data you will have to set up the encryption all over again.
What this also means is you cannot store your zips on the internal memory of your phone because those will not be accessible to the recovery. You will have to store them on either an unencrypted microSD or sideload them with adb (easy enough to do on CWM, not sure about other recoveries).
Backing up should be fine as long as you backup to somewhere other than the internal memory for the reasons I stated above.
Will the wipe and restore options work?

I have a full Nandroid Backup of my phone with 4ext Revovery Touch. So if I encrypt Internal Storage only and if it's screwed up, will I be able to restore the Nandroid backup from recovery (I mean, is it possible to modify (rwx) the encrypted partition from recovery?

If the Nandroid backup is stored on your SD card, I think so, but you might have to wipe the partition first. As far as I know (someone please correct me if I'm wrong) you can still wipe the encrypted partition, you just can't access any of the encrypted data from recovery.
Yeah, the recovery works just fine!

^+1. So I went ahead and encrypted the internal storage. The process was fairly fast (took me under 10 mins).
But entering a password was too much of a hassle. So I performed a full system wipe and restored the backup. No problems.
That actually didn't work for me on the Nexus 7.
I tried to wipe the tablet from recovery but it couldn't mount the /data partition.
I tried to wipe the tablet from the OS but it didn't like the custom recovery so it just rebooted without changing anything.
In the end I had to run "fastboot erase userdata" to wipe it. That worked.
I have now installed CM 10.1 and can report that the encryption process seems to be working fine on the N7. It's taking a while but it is the 32GB model.
Encryption on Android is very temperamental. The general pattern seems to be that if the ROM you're using is based on the stock OS for your device (as AOSP is for Nexus devices) encryption will work fine, but due to the way the memory is mounted on modern Nexus devices, recoveries may be unable to mount the /data partition at all.
However if you are using a ROM based on a non-stock OS for your device (e.g. AOSP on an HTC Sensation) encryption may not even be able to turn on, and sadly fixing this problem when it arises is not high on the list of priorities for most developers, especially if your device isn't popular.
We are lucky that CyanogenMod seems to care a lot about privacy and security recently however. That may mean they focus more on encryption compatibility in the future, and most AOSP ROMs are based on CM, so fingers crossed for that.
But basically be aware YMMV when it comes to encryption on custom ROMs.
I tried to encrypt two Moto G's with the new official CM11, but after reboot and enter pin to unlock, the devices crashes with a black screen.
Encryption with stock firmware works fine.
This is so annoying thing for me. Every time when I want to use TWRP because of encryption I must format /data. Is there any chance to avoid this step? I want to have TWRP but I have no OTA. So, I need to download ROM, enter TWRP /data and always from scratch. So idiotic
How to not format /data and still have TWRP full operational?

Use Orange Fox Recovery

Hint: OrangeFox does not do*anything*(eg, encryption) to your data partition. If your data partition is encrypted, it is normally something done by your ROM. Sometimes it depends on a setting in your ROM's configuration - but some ROMs force encryption by default.
Which doesn't solve problem

Format your data, install the OrangeFox zip again (because formatting data will have wiped the internal storage - which includes OrangeFox's files), tick "Disable forced encryption" in the OrangeFox settings, and install your ROM. OrangeFox will remove the forced encryption settings in the ROM that you have just installed, and you shouldn't have a problem with forced encryption with that ROM.
hello,
As I face some issues with my rom thought to do a fresh start by resetting the data partition via orange fox recovery which bases on twrp and try to flash another rom. but once I wiped the data partition recovery could not decrypt the internal storage data on the next boot. honestly, this issue happens to me several times, and thus thought to start a thread for some helping hands for this issue. if anybody faces this please let me know the solution. thanks
somehow I got the data partition decrypted by re-flashing the same rom

You didn't get it decrypted. It's still encrypted but since you flashed the same rom that was there, the encrypted data partition is readable again. If you try to install a different rom you must FORMAT data partition to decrypt it. Wiping is different from formatting.

Well Me too faced this with "Curtana"
I forced to use SD card to copy the rom to phone and install it.
( I will test today Pixel experience Recovery to make sure )
Recovery tested:
-Pitch black recovery project
-twrp by mauronofrio
You could have sideloaded the ROM from your computer. No need to use separate SD card for ROM installation and it's also faster.

my adb sideload is not working. it's goes on then say failed. what to do?
Hi everyone,
I have a issue with my device I wiped system cache and vendor dalvik cache but skipped data as I always do but for some reason I am unable to decrypt data after clean install of Lineage OS. Actually I wanted to remove Magisk so I just wiped those and installed same version of Lineage that was on my device. Even TWRP is unable to decrypt now. Any help is appreciated.

I have same issues as well. Did you manage to find a solution?
I tried to flash whatever LineageOS ROM was available but I was unable to decrypt as after a time I got message that the encrypted block might have been corrupted since my password was correct it can not decrypt full data and partial decryption was not possible.
I had to WIPE ALL and start afresh again. But I would suggest you to try different versions (different build dates) of Stock LineageOS ROM to try to decrypt data before you give up.
Last resort if WIPE ALL and start afresh as there is no way that I know of for partial decryption or external backup and decryption.

would you mine explain some more about WIPE ALL? Like in formatting? Because format is no used for me and I did make sure there is no password.
Wipe All means: Wiping Data + Cache + Internal Storage
(complete fresh start of ROM without anything on phone, similar to formatting all data on device or factory reset on stock decies)
Well you should only do Format data only as last resort to make phone usable since decryption is no more possible.

Well I tried everything you mentioned and nothing work. All i got is a while bunch of "error opening" "permission denied" with my internal storage. And bootloop if i install anything not Lineage based
Well installing other ROMs other than official LineageOS ROMs will not work. It seems either your storage has been corrupted like mine was.
If that is the case then formatting data and storage could be the only solution to make your phone work again, but that will mean you are starting from fresh on your phone without any data. (YOU WILL LOSE ALL ENCRYPTED DATA.)
In LineageOS you have to completely wipe data to remove encryption. There's no other way.
Hi, Orangefox can't wipe data, it gives me this error: unable to mount storage. I think the problem is that the data partition is somehow encrypted, but i haven't encrypted it so now I can't decrypt it because I don't have the password. I've already tried with the unlock password but it fails. I know the easy solution would be to format all data including internal storage but I would like to avoid that possibility. Do you know what can I do?
(The CrDroid rom I was installing before this problem occurred is in bootloop, so I can't access it).
Have you tried other recovery? TWRP, PE, Miui.
TWRP tells me the same thing: Unable to mount storage
I think the only solution is to format data. Is there a way to recover the files? I have no backup.
Data return is possible. Formatting must not be done and you must load the ROM from which the data came. That is, the last working ROM. After running it, then back up the data and only then try a new ROM where the data will be formatted.

How do i load the rom? I can't install it with TWRP, it says:
Devices on super may not mount until rebooting
recovery.
To flash additional zips, please reboot recovery to
switch to the updated slot.
I've tried also with OrangeFox, same error
OK, the problem was relative to the A/B slots: by switching to the other slot I managed to install and access to the rom. Now I can recover the files, so I can format data without problems. Thank you!
