Device Encryption
good afternoon guys I need help with my redmi note 7, I already did the unlock but I can not install twrp, when I do the installation and boot, go to the encryption password screen, so that does not recognize my password and can not undo The encryption, my note 7 was with version 10.3.6 EEA, I installed the Global version 10.3.10 and still did not remove the encryption, already updated to the latest version and does not work.
I can't undo device encryption and install twrp .. I did all the procedures I found and it didn't work.
It seems like even if it says not enough space, data has been transferred to SD though
i think you have to format data partition
u need to factory reset from twrp NOTE , there is a difference between formating the data partition and factory reseting to remove encryption

Here is a quick review of what happened:
The phone was running well on Lineageos 14.1, encrypted with a pattern, with TWRP 3.1.1 as recovery. I’ve then been notified of an LOS update to 15.1 Oreo and got excited. Booted in recovery, entered my pattern to decrypt, took a full TWRP backup, flashed Oreo modem and firmware and dirty flashed (I know, bad idea) the LOS 15.1 zip.
It got stuck at boot logo. Even if I didn't have high expectations for it to work I just thought I would try the lazy way to see and use my fresh backup to restore in case of failure like I always did successfully since my Nexus One.
This time was different because as I rebooted in TWRP to restore, it didn't ask for my pattern. You guessed it, the data partition is encrypted, no access to my backup or anything on the external storage. I can mount data and see the weird encrypted file names but that's it. I tried different version of TWRP, but it never ask the pattern. Even the terminal command 'twrp decrypt *******' doesn’t work.
I then tried to wipe data and flash LOS 14.1 again but it gets stuck saying that android has no access to data partition because it’s encrypted and that I need to format. I pulled out my sim card and started to use my old oneplus one while waiting for the new version of TWRP 3.2.1.1 with the feb security patch support thinking it might then be able to decrypt but no luck still.
I can go without the phone for a while, I’ll buy another one if I have to because there is some precious data on that phone and I can’t make my mind that the data is there, I know the encryption key but I have no access to it. There must be a way, I just don’t have enough knowledge about how this encryption thing is working.
Any help would be appreciated, Thank you

Try flash codeworkx TWRP ...
it should decrypt your data partition ...

I had tried it when it came out and I just tried it again. No difference!! It looks like twrp doesn't even see that my phone is encrypted. I've read a lot and tried many different things and I'm out of idea. All of the people I've seen with this problem have given up so they could get their phone back and running by formatting the partition, losing their data. This option is not one for me. I'd rather buy a new phone hoping for an eventual possible solution. I know the data is there, and I know the pattern key...... I mean, there's got to be a way......
Ok have a ZTE Axon 7 can't flash any thing because of it instantly encryption and I get recovery and then game over any one have a Cure for this......... thanks in advance.
You have to do a factory wipe, to remove encryption. Then when setting up the phone again when it prompts you to set a security pin or finger sprints skip that part.

Tried that and it didn't work.....it doesn't matter what I flash stock ROMs tell me my password is correct but memory is corrupt and need to be wiped and when I flash a custom ROM it doesn't boot just two flashes of the led and that's it.
Which TWRP recovery are you on?
What I mean by Factory reset is a full Factory wipe your whole internal is erased. It is like a clean slate new phone.
You should have all the necessary files for your flash on your sd card there is an option to select storage to flash from there.
So when I first swapped from Stock Nougat to AEX I was encrypted on 5/4 ROM my internal was locked by encryption and could only dirty flash roms. it was annoying so I factory wiped and flashed latest AEX from there and didn't set up security right away so no encryption.
I realised my TIBU back ups were all on internal so had to basically start from scratch oops lol.
It is a little outdated now with the official Oreo roms but user @Oki 's guide helped me a lot and has clear steps and guides to get you all rooted and sorted on custom roms.

Ok now got the thing back was able to reunlock the bootloader and installed recovery flashed candy rom with one issue could not mount system so now just flashed Oreo stock rom so all good again....... thanks for the help
The stock ROM encrypts by default, and formatting data partition in twrp is the only way to remove it. But to prevent the encryption before it happens, you have a few options:
1. If you dont plan to root, flash @jcadduono's no verity opt encrypt zip (Google it)
2. Magisk and SuperSU can optionally disable encryption before it happens. Magisk Manager has a config option if you're installing from the app. You can use Aroma SuperSU config if SuperSU is your root method of choice.
Hope that helped!
I would like to note that AOSP/Lineage/CM-based ROMs dont encrypt by default. though Im sure it could be enabled if you wanted to. This seems to be unique to the stock ROMs, mainly because Google insists that phone OEMs should go for higher security by enabling encryption as the default.

Yep this is the problem I am having now....... can't find much info about it.
Hello everyone,
How I can decrypt mi 9t with global/eea ROM?
Which recovery I have to use?
And what steps should I do?
Thanks
Simply remove your lockscreen security. Once you done tbat, encryption is gone. However, if you factory reset while you still had encryption (lock screen security) you have no other alternative than wiping your internal storage.

Youre wrong. If You remove lockscreen security Your data is still encrypted. You can check it in Settings,Addatoonal Settings,privacy,encrypt phone.
Only way to remove it is format data but beckup Your data first to computer or USB drive otg.
I'm currently using the 4pda twrp and formating Data does NOT decrypt the Partition for some reason. I even got the xiaomi.eu and havocOS working in encrypted Mode before. Ist there anything I am Missing / can decryption bei done manually? I dont want to run into problems later on.
I've just moved from MIUI 11 to custom Q roms recently and I faced the "Data partition is encrypted" error when I open recovery. I read that I should format the data partition and reboot recovery but I tried and after rom starts, I opened recovery and the error appeared again.
I tried:
Formatting data before installing new rom
Formatting data after installing new rom
Try another Q rom
But nothing changed.
I'm using OrangeFox recovery.
Any suggestions? Thanks in advance

Most lavender ROMs will encrypt automatically an unencrypted device when booting up for the first time. This is for a very good reason - without encryption, some things (PIN/password, fingerprint) will not work on this device.
The only way you can prevent such automatic encryption is to format data, reboot OrangeFox, tick "Disable Forced Encryption" in the OTA settings page, and then flash the ROM. In most cases, this will be enough to prevent the ROM from encrypting the device. However, I would very strongly advise you to NOT do this (for the reasons stated above). Let the ROMs encrypt, and live happily with the encrypted device!
Good to know your solution.
I want my de vice encrypted. But what the purpose to have à encrypted phone without knowing the key pass?
We are not able to wipe cache and delvik, so we can't update the ROM version and get last security updates.
How can we encrypt the phone using a clean way?
what orangefox version you are using? and before you reply.....PLEASE UPDATE TO THE LATEST 10.1, because version 10.0.1 is obsolete at least three releases. (thats the only thing i can think of - solution for your problem)

Hi
I was trying to flash xiaomi.eu (xiaomi.eu_multi_HMK20MI9T_V12.5.2.0.RFJCNXM_v12-11) custom rom to my Mi 9T device via TWRP recovery
I booted into recovery then I noticed TWRP isn't asking for a password for decryption
So dumb me ignored it and "Advance Wiped" all partitions except "Internal Memory" and flashed the rom from "USB OTG"
then problems started to appear
first the rom didn't boot and was stuck in a boot loop
so I wiped and reflashed the original "miui_DAVINCIGlobal_V12.1.4.0.RFJMIXM_e0ac13ed89_11.0" rom via TWRP from "USB OTG" to be able to back up my files and do a proper format/decrypt
but the internal storage is now still encrypted and cannot be accessed
I tried twrp decrypt command with all combinations of passwords pins pattern numbers that I used since first bought the phone but none of them worked
I know I should have backed up my files
Now I want to know how can decrypt /data/media/0 aka /sdcard aka Internal Memory and get my files
like mounting it in windows through some adb and other software and decrypting with known key combinations and passwords
or through twrp or whatever that maybe work
I really can't afford to lose my data AGAIN
yes, that wasn't my first time!!!!!
I promise if this gets right I devote the rest my life to the open-source community
excuse me for my bad English.
When flashing a custom ROM, or going back from, you HAVE to Format (not just Wipe) Data
(And you don't need to wipe System because new ROM will overwrite it anyway, and you better never wipe Persist and so)
Obviously, you must backup your photos, data, etc, before switching the ROM
Data on Internal memory is encrypted, and not by your unlock pin (unlock pin just serves to verify and read the key).
New ROM reinitializes the encryption key
Hence, AFAIK, you cannot decrypt anymore because you don't know the encryption key that was used for data on your Internal memory
Seems you have similar problem as I have

ok
a question
why the twrp was not asking for decryption in first place?

No idea - ask devs of your custom ROM how they implement encryption and what is the proper way to install the ROM
