Help Decrypting OOS - OnePlus 3 Questions & Answers

Hi everyone
I am trying to install multiROM, i flashed TWRP-multirom, flashed multirom.zip but, multirom won't boot.
When i try to decrypt OOS, using fastboot format userdata, reflash etc... OOS in security tab say "Encrypted".
What i have to do?
If i restore "/data" backup created with TWRP BEFORE decrypt, does the rom get encrypted again?
Thank you for all!

Please Help!! Phone reboots to TWRP and not to system

Please help me,
i have the MIUI8 Developer ROM and i updated it to Version: 6.9.8 (MIUI8) yesterday and found that root function was not working so i installed TWRP recovery again and since then my phone is just rebooting to TWRP.
I tried wiping the data, factory reset, restoring from CM13 backup and MIUI8 Stable ROM backup, installing new ROM but the phone is just rebooting to TWRP after all that.
I also tried this from an earlier post:
http://forum.xda-developers.com/showthread.php?t=2451696
still nothing works.
Please help me resolve this.
I had a similar problem. I fixed it by fastboot flash using the stock rom which would also overwrite the recovery partition. Then flash back TWRP and CM13. Save your data using TWRP before doing any destructive writes.

I tried no verity v1 v2 v3 no works, still ask to encrypt.

Would you like to share the solution?
You have to be aware to flash a rom after you wipe data partition you need to change data partition to EXT4 for example to prepare to flash a Rom). All of this has to be done while in Recovery before you reboot. It happened to my device when it warned me that i have No OS.
If recovery cannot be flashed correctly, try the TRWP CN version mentioned on page 6 in the AOSiP thread, and if anyone has trouble after changing to EXT4 which is required to flash Custom Rom, just change the data partition (EXT 2 for example) on the advanced wipe/ change partition option, and then change back to EXT 4. And follow the instructions on AOSiP on how to flash properly.
That TWRP worked on first try in case the others don't work.
After boot to the rom... you can go back to Revovery, and flash Nigel's TWRP, and you will not have anymore problems with wiping data and doing OTA manually. (Whenever there's an update)

Can I update to Pie via TWRP, after editing updater-script, if yes, can I flash decrypt.zip just after updating without formatting data. Actually, I don't want to format my device and install all the applications again.
Is 1903.064 is stable enough to use, I mean cam2api, screen flickering, PUBG on HD setting, charging time it was taking too long to charge earlier, reduced battery backup, screen brightness, cracking sound, double tap was also not working.

Yes. You can. But if the phone is encrypted and flashing decrypt for the first time, decryption comes into effect only after formatting data

No, Mine is decrypted. I am on Oreo with TWRP and already flashed decrypt.zip of Oreo? So can I flash 1903.064 zip via TWRP, after editing updater script and then flash decrypt.zip of Pie, to save my data partition?
I hope decrypt.zip of Pie does not format data while flashing.....

Flashing decrypt oreo infact caused many problems on wifi/modem for many users. Also decrypt oreo didn't worked on pie for some users. So flashing decrypt pie is recommended for Oreo too.

I'm confused and the rooting step
Hi all. I have zenfone updated to Oreo/android 8.1.
Phone model Z01BDC = ZC551KL .
What should I do to apply this patch to decrypt my /data ?
I installed TWRP 3.1.0.0 and the fact that /data is Encrypted is a problem.
Thank you.

This mod works in X01BD and X00TD. Not sure if it work for Z01BD. You can flash this patch by following the steps in the thread but success isn't guaranteed. Take a system backup as if anything goes wrong. Also be ready to loose your data

I'm not sure about that... I am flashing this file (decrypt pie) for Oreo just. The phone does not boot in this case. I was forced to flashing old decrypt file for Oreo after and it all worked again.
It's not working with Official TWRP 3.3.1-0. I'm using stock Pie .065. Every time I reboot to system, it starts encrypting my device and when I reboot to recovery, TWRP is gone and I'll be booted to stock recovery. Then I flashed TWRP and checked the fstab.qcom. It was never patched. With OFRP, I don't have this issue as it patches fstab.qcom automatically after flashing a zip. But with the zip provided in OP, I'm unable to disable forced encryption. I don't get any error while flashing the zip though. Does any other file needs to be patched to disable forced encryption other than fstab.qcom?

I think twrp official has decryption issues. Check with twrp 3.2.3

I checked with Rk585's TWRP 3.2.3 too. Same issue persists. It worked fine when I was in Oreo.
After flashing the zip, I booted back to recovery and copied the fstab.qcom to my PC to check if it has been replaced with the flashed zip. It did replace it. But when I boot to system, it starts encrypting my device and TWRP gets replaced by stock recovery. So I flashed the TWRP again and checked the fstab.qcom. Voila. It was unpatched. I don't know what is happening during the boot. The patched fstab is getting replaced by original fstab.
Edit: Seems there is a problem with the zip I guess. Or more files need to be patched to disable forced encryption in stock Pie rom. I tested in both PBRP and OFRP.
Case 1: I flashed stock rom in Official TWRP, then flashed PBRP zip and booted into PBRP. After booting into PBRP, it doesn't automatically disable forced encryption if no rom zip is flashed in it. So I flashed the decrypt zip provided in this OP. Then I booted to system, it started encrypting my device.
Case 2: I flashed stock rom in Official TWRP, then flashed OFRP zip and booted into OFRP. After booting into OFRP, it automatically disabled forced encryption even though no rom zip was flashed. Hence after booting into system, it didn't automatically encrypt my device as forced encryption was disabled automatically by OFRP.
So PBRP and OFRP do something else to disable forced encryption other than just patching fstab.qcom. Atleast in stock Pie rom. That's why I'm unable to disable forced encryption by flashing decrypt zip in any of the recoveries unless it is patched by recoveries themselves.

[AOSiP, Android 9] Not booting after OTA on encrypted device

I hope that someone here can help me rescue to rescue my data.
I was on the AOSiP build from september and than decided to encrypt my device. That worked perfectly. Now I wanted to install the latest update. The internal updater didn't work (just booted into TWRP recovery without further action, so I moved the update file to microsd and than updated manually by flashing the zip file via TWRP). Prior to the whole action, I updated TWRP through the app to the latest version.
Now my phone doesn't boot anymore, it is stuck in the AOSiP boot animation. Reverting to a previous TWRP version (3.2.3.2) didn't help, also flashing the september build again didn't help.
In TWRP I was unable to decrypt data, because TWRP keeps asking me for a password (but I don't remember putting a password in the first place). Therefor I switched from TWRP to OrangeFox recovery. Here decryption worked, put still after flashing the phone doesn't boot.
Anyone that has further ideas how to fix this without loosing all my data? Any help appreciated!
Have you tried installing another kernel?

No, but as my system was running before without problems I don't expect the kernel to be the problem .. Or why would that make sense?
SOLVED: I noticed that flashing the update manually didn't automatically flash Gapps right afterwards. So flashing the Gapps helped and the phone now boots normally!
