[Q] How to wipe Data partition after it's been encrypted?

Hey guys,
My work switched to Google Apps for their email so i wanted to test it out on my phone. Doing so required them to encrypt my phone. What this appears to have done is encrypt the data partition. So now when i go into (TWRP) recovery and try to do a backup / wipe / or anything else, it says it is "Unable to mount /sdcard" I'm unable to do a factory reset of any kind so i'm essentially stuck on this rom (ARHD) until i can figure out how to wipe data and get the /sdcard to be not encrypted. Does anyone have any ideas? I'm imagining that with the modified recovery not being able to access the data partition that i'm going to have to do some adb type stuff?
Please help! I want to keep flashing new roms!

Anyone??

I think you can't decrypt your data partition...
Did you try to wipe your data partition with the latest TWRP?

That's the thing, the recovery can't mount /sdcard so wiping isn't an option from recovery

Hi! Only TWRP recovery can solve your issue just do this...
Boot to TWRP recovery->Wipe
From there there are 2 options the left is the advance wipe and on the right is Format Data
Just select the format data button and it should reformat the whole data partition.
1st one would prompt so many errors and reformat then reformat it again 1 time and it should fully reformat your phone.
In theory it should reformat data partition even when encrypted but just in case it fails and I won't be able to go back to this thread just boot in bootloader and type
"fastboot erase userdata"

Well none of that works. TWRP doesn't support decryption yet for this device.

What I instructed basically doesn't decrypt the partition. It reformats it.

I know what you instructed, it doesn't work. Only way I got it to work. Flash the stock recovery. Boot into system. Take off the encryption, phone reboots and removes the encryption, data is formatted. Then flash TWRP again.

I basically ran into this exact problem. I was hoping that I'd still be able to back up the encrypted device, but forget about it. What a pain in the ass.
Someone should make add something to the guides about how encrypting your device makes nandroid backups impossible.

After wiping data, TWRP no longer asks to descypt storage. Cant access files.

I switched over from xiaomi.eu to MI Room. Seemed to work fine until a magisk module uninstall screwed up my ROM and caused a bootloop.
Figured I would do a factory reset, however now Orangefox recovery no longer asks for a decryption password. I know the password, so how do I decrypt my storage?
Thanks

It doesn't ask for a password because the encryption files were deleted so twrp would not know what the encryption data is. But miui encrypts your data when you set your pin/pattern and the userdata remains encrypted when the encryption keys get deleted. The only way is to format userdata.
I also want to know a workaround for this. If you format userdata and flash recovery version of your rom, will your data get encrypted again when you set a password? Because then, any backup made with your data encrypted is unusable. Is data encrypted only on official roms but not for lineageOS etc?

My encryption files actually weren't deleted. I did a factory reset and reinstalled the previous ROM I was encrypted on a few times and somehow it decided to allow me to decrypt my storage again... So I managed to back things up, then format and wipe all storage and flash the new ROM. Working fine since.
Thanks for the help though.

decrypt without data lose

Hello everybody,
I flashed some rom from other forum which changed my vendor(i guess by twrp messages) and I forgot to flash disable force encryption zip, so now i have encrypted storage, no system and some different vendor which wasn't on my device by default. I have access on twrp and fastboot and all but how can I install system on encrypted device without losing my data(factory reset to decrypt storage) phone?
Edit: by data I mean internal storage not app and rom data. I already wiped them.

copy data to pc or in pendrive using otg then proceed

[Solved] How to reset / clear TWRP's password

Hello everyone, I changed my Redmi K20 Pro password but I stopped using it and forgot the password. Is there a way to clear TWRP's password, uninstall TWRP or even change the phone's recovery back to stock? Anything to regain access to the phone. Thanks for the help!

If you mean the lockscreen security password/PIN, then there's no solution that won't allow you to keep the data currently on the phone. The simplest solution is to format the data partition in TWRP. In this case is doesn't matter that you don't know the lockscreen password when entering TWRP. Just hit OK and you'll get a message saying it failed to decrypt the partition, but afterwards you'll still be able to format the data partition.

Thank you Robbo.5000. I had already formatted Dalvik, Cache, System, Vendor, Data and Internal Storage but I didn't pay attention to the Format Data button on the previous screen. Problem solved!

Question Unable to mount /system.

So I was trying to install viper4arise using their own tutorial [https://forum.xda-developers.com/t/...ditory-research-in-sound-enhancement.3379709/] using Orange Fox Recovery. Also, since I can't access the /sdcard partition using the recovery, I used adb push to transfer the zip file to be flashed.
Then while flashing the zip, it requires access to /system and hence while flashing, it shows "ERROR:1, unable to mount /system."
I've heard that data is some kind of encrypted and to remove it I have to do "Format Data".
1 - Is there any other way to decrypt than doing a format data?
2 - Also once i do format data can i keep my storage unencrypted someway?
3 - And most importantly, what exactly does "Format Data" do? Which files does it remove and will I have to reinstall my stock ROM after doing it.
Thanks a lot and I'd love if you answer my questions part-by-part.

Probably needs to root the device.
1 - Is there any other way to decrypt than doing a format data?
Remove all lock screen security
2 - Also once i do format data can i keep my storage unencrypted someway?
Once you have installed a rom and added a security on the lock screen.
3 - And most importantly, what exactly does "Format Data" do?
Format data delete all your content and create a new partition if necessary.
will I have to reinstall my stock ROM after doing it?
yes.
