[Guide] How to Remove Device Encryption to Flash Custom ROMs

The Issue
The device does not allow to use the newly flashed Custom ROM as it is Encrypted thereby asking for Password every time the phone boots up and wiping Data Partition with a Custom Recovery also does not work.
The Solution
Step 1 - Type anything as Password when the device asks for it after booting up. Be Quick as the device will shut down if you don't type anything within a few seconds.
Step 2 - Check whether it says Decryption was successful but the data is corrupted and also instructs to do a factory reset by tapping the Reset button. If Yes then go to the next step as the subsequent steps will resolve the issue. If No then this guide can not help you.
Step 3 - Do not touch that Reset button and reboot the device to Recovery by long pressing the Power button and then pressing Power and Volume Down simultaneously and choosing to go to Recovery from the Fastboot/Bootloader Menu.
Step 4 - Now connect the phone to your PC and transfer everything from your internal storage (if you didn't do it before flashing the Custom ROM) using MTP as the next steps will wipe the internal storage. Eject your SD Card from the device.
Step 5 - Download the Platform Tools from the link : [url]https://drive.google.com/open?id=1LEcF5iAjRdno2_aPKv9DYdOYtviC5xB7[/URL] and after extracting the folder place it in the C drive.
Step 6 - Install Motorola Device Manager from the link : [url]https://drive.google.com/open?id=12k2joSx5G08oourGlYLdtLEdTuOC9CVb[/URL] on your PC.
Step 7 - Download the Stock Recovery from the link : [url]https://drive.google.com/file/d/1_gogMT_GgSvg6FKpe2q4Z51gh22ftUdt/view[/URL] and place it in the platform-tools folder.
Step 8 - Assuming that your phone is still connected to the PC go to the Fastboot/Bootloader menu on the device by using Reboot to Bootloader option from the Recovery.
Step 9 - Go to the platform-tools folder on the C drive of your PC and open a Command Prompt window there by holding Shift key while Right clicking on the mouse and choosing the option. Enter the command fastboot devices to ensure that your phone is connected to the PC.
Step 10 - Enter the command fastboot flash recovery recovery.img to flash the Stock Recovery on the phone.
Step 11 - Reboot the device and enter anything as Password when the device asks for it. Now tap the Reset button to do Factory Reset. The phone will reboot to Stock Recovery and ask you to perform Factory Reset. Choose Yes to proceed and it will take a few seconds to do so. Voila!!! Your phone is successfully Decrypted and now you can boot into the Custom ROM you flashed.
Step 12 - As the phone is already Decrypted there is no need to keep the Stock Recovery. You can flash the Custom Recovery of your choice by going to the proper website and following the instructions to flash it on your device.
N.B : It took me a couple of hours to figure out the solution to this issue when I faced it and I wrote this guide so that it will help people who face the same issue in future. A Thanks! is much appreciated .

I work with "format data" in twrp

That didn't work in my case.
Otherwise it's the easiest way to do so.

I also do not work the "format data" the first time. you have to do it once and gives error, then restart , go to twrp and do it again and there if it works. and reinstall the rom again ... after that you can change rom normally

I did it at least four or five times and was unsuccessful.
The phone was only booting up normally with Stock ROM but always asked for Password if any custom ROM was flashed.
Then only I came up with the idea I posted here and was successful to remove the encryption.

data on the phone will not be deleted?

Step 7: ". . . the next steps will wipe the internal storage. Eject your SD Card from the device."
You should expect that data will be deleted.

Yes!
Step 10 will wipe the Internal Storage and the SD Card too if it is still in the device.
It's a safe practice to eject the SD Card before doing any operations.

Is this still required for Pie ROMs? I've unlocked my bootloader, installed TWRP and called it a day, didn't have to change anything, but I'm still on stock Oreo.

If you're still on stock and haven't flashed any custom ROMs in the past or decrypted your data by using the "format data" command in TWRP after unlocking the BL (like I did) your data partition should be still encrypted. Most custom ROMs, regardless if they're Oreo or Pie don't work with an encrypted data partition. If the developer of the ROM you'd like to flash doesn't recommend anything else you can decrypt by using the format data option in TWRP (the one you have to confirm with "yes") or maybe by following this guide, for me that was never necessary, you just may have to use "format data" twice to make it stick.
To prevent your system from re-encrypting you can flash magisk or use a disabled dm verity force encrypt zip:

The only time I've formatted /data was when I unlocked my bootloader. Immediately after this I've flashed TWRP, booted into it, installed magisk and restarted my device. It didn't asked for password or anything, this is why I'm confused. Since I haven't formatted using TWRP, it should be encrypted, right?

So since I installed magisk, then it shouldn't be encrypted, is that it? Sorry to sound soo noobish, but its been a while that I'm not flashing stuff and the last time I would just flash anything with no issues with encryption.

It shows that my device is encrypted. So, to decrypt it, I have to wipe /data from TWRP, right? To make sure that it won't get encrypted again I have to wipe twice, or just flash the script you linked?

To decrypt it format/ data (not wipe, that's not enough, it's the option where you have to confirm with "yes"). As I did that I formatted data and after that flashed magisk. It doesn't work at first attempt so I went into TWRP and did it again.
Normally magisk should prevent your device from re - encrypting, if not flash the attached zip.

Do I need to select "Format Data" under "Wipe" to decrypt it? On TWRP, I see Wipe -> Format Data. If yes, do I need to remove SD card that has my system backup and custom ROM? Thanks.

Are you referring to the "Format Data" tab under "Wipe" (that is, Wipe -> Format Data next to Advanced Wipe)? If yes, do I need to take out a SD card where I have a backup and custom ROM? Thanks.

[HELP] XT1794 stuck at fastboot/twrp after infinite boot anim on the latest los16

Hi everyone, I was usually providing help on this forum, now i'm the one desperate for help after some unforeseen consequences.
Bear in mind I'm kind of a noob anyway.
I have seen the message on the telegram groups for our device regarding solving the los 17 problems with the ril and camera. So i have followed the steps. I flashed the last twrp 3.4 by jarl using the official twrp app and then rebooted to recovery, wiped everything beside the internal storage and tried flashing the last los 16 zip.
And then the disaster happened. firstly the log returned error 7 so i've rebooted to recovery again and attempted to flash the same zip again without wiping anything. well the flashing worked apparently but i couldnt boot into it as it showed me an infinite boot animation.
Then i rebooted to recovery and it prompted me with a decryption key request which i didn't set before. I cancelled the prompt and I moved forward and proceeded wiping everything including the internal storage thinking that was the problem. Maybe it was maybe it wasnt, now I'm no longer prompted by any decryption key, but I was hoping i could connect to my pc through mtp, transfer some zips and flash some functional rom. Even though I enable mtp and my pc detects the phone I can't access any storage nor the internal, nor the sd card.
I tried going through multiple versions of twrp as i can still access my bootloader and i can still flash recoveries through fastboot but i feel that i'm stuck and I dont know what i should try anymore.
Before trying all this I was on an older build of los16 with the oreo firmware.

First of all, use this TWRP: https://build.twrp.me/twrp-3.4.0-0-montana.img
Second of all, do not flash TWRPSARer (if you did). Make sure the LOS16 zip isn't corrupted (which normally causes error 7), then format system, data, cache, vendor and dalvik. Reflash LOS16 and boot

I wasnt using the twrp sar, i was using the exact version you linked. And I can't flash any rom because i cant get the zip inside my internal memory.

You can try using adb sideload. adb sideload path/to/zip

worked like a charm. thanks a lot, Jarl.

And this, is the story of someone who didn't want to wait long enough for the ROM to boot
Nah JK, but long boot-times normally = Force Encrypt Enabled

it might have been the problem, but if it is it should be a disclaimer for that on the los16 page. the boot time is way longer than the usual.

TWRP New install , New Phone issues fastboot

Did standard unlock bootloader (went fine)
Moved a TWRP zip onto phone sd root directory (twrp-3.4.0-0-guacamole-unified-Q-mauronofrio.zip)
adp fastboot boot twrp-3.4.0-0-guacamole-unified-Q-mauronofrio.img. (went fine)
But when I look for the zip file (or any system files) it does not show up , even in TWRP file manager.
Redid data wipe and it tells me "Failed to mount /system_root and /vendor
I am 99% sure that its just because these will not mount:
Does anyone have any idea what I can do to get these mounted to start a regular TWRP flash ?

Well I tried adjusting data format and ended up losing the Stock Rom.
And the stuff will still not mount.
UPDATE, rewiped data and got stock rom to load.
Now Data will load but vendor will not.
UPDATE : data and vendor will mount after data wipe. But still cannot see anything that is placed on device.
Such as the zip files I need to install.
UPDATE: now I sideloaded TWRP onto new phone, but now cannot get it to reboot into Rom.
Its odd after plugging it in , it went to a stock recovery even when TWRP was installed.
Found the issues, finally had to run MSM download tool and fix everything from there and start from scratch.
Ended up installing TWRP from fastboot flash recovery image.
Now to get root going on it and magisk.

What device do you have?
You're in the 7T forum but saying you used the 7 Pro twrp.
If you're using 7T, the reason why you don't see internal storage is because TWRP cannot decrypt on OOS (this is not because of a mounting error, this is simply due how oneplus has implemented their encryption).
And on 7T you don't need a zip of any sort to install twrp.
Reading the actual twrp thread would be a good start.

Yes, I read though the threads, But got so bombarded with pages of stuff kind of lost track.
This is why I posted . Also it is a combined Christmas gift for my daughter that she cannot know I am working on. So I think I tried to rush it when she was in school.
Found out about the decryption part after I started the process. Then it was too late and ended up having to start over with tools.
It was a newb move to end up this far and try to rush it.
People did help me get back on track and now I am working on figuring out Magisk. (good help on magisk threads).
Thanks for your response.

TWRP 3.5.2_11.0 for Oneplus Nord N100 (Android 11)

Test version of custom Team Win Recovery Project version 3.5.2_11.0 for OnePlus Nord N100 (Android 11 Only).
Everything works, except for:
MTP, .img firmware (for this you need to flash the full super.img image) and decryption of the Data section.
If anyone can modify this version of the recovery, we are very grateful to the future.
In the meantime, whoever wants to test or try it out, an image will be attached to the post. You can both boot (fastboot boot twrp.img) and flash (fastboot flash recovery_a twrp.img and fastboot flash recovery_b twrp.img).
I ask you to answer about all the problems found and write either to me personally or in this topic.

Is there any newer version of this? i find this one freezes the phone a lot. thanks

I ran this TWRP for the OnePlus N100 in fastboot and it worked but I can't see any files. I've installed Android 11.
I'm trying to install Magisk zip but in TWRP I only see the folder tree and no files.
Do I need to install TWRP and not just run it from fastboot?
If I need to install it do I pick slot a or b or both?
Thanks for any help.

I didn't. I patched firmware boot image and flashed through bootloader. However I just tried flashing from TWRP.
I put the zip on external SD because this version doesn't support decryption of data partition. I then entered the "mount" menu in TWRP and mounted external SD and then tapped "select storage" and selected external SD.
You should be able to flash it now. It didn't give any errors, but i didn't uninstall magisk first so don't know how well it actually worked.
I also don't know if you can do anything without external SD or without root access already.

I had high hopes...
I fastbooted the TWRP, I didn't install it but I don't think that would make a difference.
I put the Magisk zip on the external SD card and from within TWRP I had no problem mounting the SD card but I still couldn't see any files, just a folder tree, and every folder empty.
When you run TWRP and mount the SD card can you see the files within the folders on the card?

Yes. It is important that you tap "select storage" and select "micro sd". After i did that i entered "flash" and immediately saw folders and zips on my external sd. In file manager i could see all files and even deleted some from there.
From root directory it's in /external_sd not in /storage.
Edit: Even though i also don't think installing TWRP makes a difference, i don't know if that's the case.

I should mention i used "fastboot flash recovery xxx.img" not "... recovery_a" or "... recovery_b".
I don't know if this changes something with access

Honestly patching boot image is probably less of a headache. I can even send the images pre-patched if you want. Just one fastboot command
I'd need to know your phone variant and update version.

My N100 is a model BE2015, build number 11.0.1BE82CF
I just fastbooted TWRP again and I'm mounting and selecting external_sd but still zero files.
If I flash the TWRP with "fastboot flash recovery xxx.img" is there a way to reverse it if I ever need to?
Again thanks for the help.

Well that might be the problem. That's a carrier locked phone, right? I'm not really familiar with those. I just know they are complicated to mod.
Not sure if you'll even be able to flash recovery and I'm surprised you can fastboot boot. But in theory, (at least on unlocked phones) if you can flash TWRP, you can flash stock recovery from firmware package.
I saw a quite extensive and fairly complicated guide to fully unlock a carrier phone here on XDA, but don't know how well it works or if you have followed any of these steps.
Edit: Also found this, looks like it works with your device: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4245499/

Let me start by saying my phone is both SIM unlocked and bootloader unlocked.
The post you linked is talking about the same phone as me but the last post in that thread has an ominous post from someone on Android 11 bricking after trying that. I'm not sure if that works if you're already on 11.
I still can't understand why the TWRP can't see files on my SD card. I think the two missing elements are the fact that you have TWRP flashed to your phone and you're rooted already.
I really can't understand why being rooted would have anything to do with TWRP seeing the files on the SD card so I'm leaning toward it being flashed that's the difference.
I would like to try flashing TWRP but I'm still unsure how, plus I'm guessing I have no recovery if that goes awry.
If I could just get the zip fashed it should patch my boot.img and give me root fairly easily.
Does anyone have any suggestions as to ways back if the TWRP flash goes bad plus just what command do I use to flash it and what happens to the other slot?
.

Okay, so...
I have now tried flashing stock boot and stock recovery on both a and b, verified no root access, then trying "boot twrp.img"
Still able to see files on micro sd.
I then attempted to flash magisk zip to verify this method working.
Didn't seem to work at first, but i think this was due to me messing something up with active slot. Fastbooted into twrp again and flashed magisk again and it works.
So, in short; This absolutely works on a BE2013, but this recovery might not play well with your BE2015.
OP asks about potential problems so maybe you'll have luck messaging him and you could investigate together? Just a suggestion.
I'm sorry, but I really don't know how to help with that model. It's problematic that there's no firmware payload available. If you find one or if you can somehow dump the boot image from the phone then I'd be optimistic and happy to help any way I can.

OnePlus 7T Android 12 TWRP?

Hello! I'm very new to building custom recoveries, and haven't even completed a successful build yet. I have a OnePlus 7T model HD1905 (aka North American model/Global) running OOS 12. I've tried to find guides on how to make a TWRP recovery, but nothing has worked for OOS 12. I am able to extract the OOS 12 stock recovery.img with Payload Dumper, and am able to create a basic TWRP device tree for android 12.1 using the official TWRP 12.1 Github manifest, but I'm not able to find a good guide to create a TWRP-ready device tree from my stock recovery.img I mentioned earlier. I've tried updating to OOS 11, and using the twrp-keep module on the magisk modules github to keep the official TWRP installed. (It support OOS 11, but not OOS 12). I've also tried flashing the unofficial build made by Mauronofrio, but none of the specified methods have worked. Can someone please either make a OOS12-compatible version of TWRP for the OnePlus 7T, or if they can't do that, guide me in a step-by-step process on how to do i myself? Any help would be greatly appreciated.

Oos12 does NOT support twrp nor does A13

I compiled it but i didn't test it with oos12 (fbe) and custom rom a13 (erofs). I hope it will work..

I just flashed it, and it booted successfully! I'll let you know if I can format /data.

Format /data works.

For confirmation, I flashed the .img of the OOS12 version to the recovery partition.

So... upon further inspection, there's an issue with decryption. I can successfully flash the image to the recovery partition, and it boots just fine. When I tap on "Mount", all of the options are unchecked. One of the buttons is called "Decrypt Data". I currently don't have face unlock, fingerprint unlock, password or PIN set up, and it still promts me for a password when I tap on "Decrypt Data". I've tried entering "default_password" and "password" (but without the quotation marks), but neither of them work. Is there a way to solve this? This is on the OOS12 TWRP, btw.

I just tested the non-OOS Android 13 TWRP file, and it has the same issue.

Can u back up all partitions except data? At least that would be helpful

Nope. Even when I de-select Data, and select everything else, it still fails with the "Failed to mount /data" error.

Yeah, I was afraid of that. No one has cracked twrp for oos12 yet

I mean, at least both of them boot.

Hi again. As I've mentioned, both TWRP images boot just fine. However, I am unable to mount /data, as when I enter the "Mount" section of TWRP, nothing except the Cache partition is checked. It doesn't ask me for a password upon booting into TWRP, however it DOES ask for one when I tap on the "Decrypt Data" button in the "Mount" section. I've tried entering "default_password" (without the quotation marks), "password" (again, without the quotation marks), and also my password that I set up when I flashed LineageOS 20. I'm curently running LineageOS 20 on the device. I'm able to access USB OTG in TWRP, but I'm not able to flash anything from there. I'm also unable to change boot slots, or backup any partitions. Formatting Data doesn't allow me to access the data partition on rebooting, and the only fix I've been able to find is changing the data partition format from ext4, to ext2, and then back to ext4. This only works temporarily, and only with OxygenOS installed. Even then, after I change the data partition's format like I mentioned above, it resets my data, as is expected. After setting up the device again, and rebooting into TWRP, the /data partition goes back to being un-selected, and I have to repeat the process over again, and once again lose my data. I am unable to carry out the process described while running LineageOS, and its respective TWRP file that you have made. Any help would be greatly appreciated, and if you know the password that TWRP is asking for in the Mount section (when I select "Decrypt Data"), I'd like to know what it is so that I can hopefully get the rest of TWRP to work. Even with these issues, I'd like to give MASSIVE thanks to you, because you were able to do something that my inexperienced self was able to: That is, create a TWRP file that boots, made from the latest custom rom files, and the latest OxygenOS versions' files.

Thank you for testing the builds and for the feedback . I've been on oos11 for a long time, but today I'm going to flash oos12. Because i would need recovery log files to fix errors.
I don't have no time for some fixes, i will try to fix errors whenever possible.

did you not ttry to use the twrp and the twrp installer builds that are on official twrp site for one plus 7t

then how are folks then flashing roms to one plus 7 t devices if there is or isnt a working twrp .

Every ROM comes built-in with its own recovery. So you'll have to flash the ROM via that recovery's ADB Sideload feature.

lets hope you can get a working twrp going for both andrid 12 and 13 .as my one plus 7t is just been put away in my drawer after seeing that one plus has given up on these older devices. when there is a working twrp i would probably want to flash something down the road. my primary driver unfortunately is a samsung S21 plus .

All works until I tried to restore. Then it got stuck at red dot going around in circle. When I tried to go back in twrp again to format data, it won't mount data after that. Ended up having to restore all over using msmtool.
It mounted data fine before I tried to restore the data part, then it messed up decryption of data despite not having a lock code, no fingerprint, no pattern-lock, or lock screen enabled.
