Guys help me- I cant decrypt my phone - Galaxy S 4 Q&A, Help & Troubleshooting

So, last week i installed 6.0 CM 13 android, I've encrypted the phone and everything was fine, two days ago I've installed new ROM (also android 6 cm13 ) and phone was still decrypted, after boot i was asked to enter my password and everything was fine.. .Today I've restarted my phone and when I try to enter password after boot it says that PIN is wrong.... I've tried to do WIPE from TWRP but it says that cannot mount partition ( TWRP asks for password too)..
What can I do? Sorry for my bad English.

Flashing the stock ROM might work. But you'll use everything.

Encrypted password failed

I updated to the mixrom TWRP via Flashify in order to flash updated ROM.
Once in TWRP (it took password fine during first loggin) I:
Cleared Cache and Dalvik
Flashed Rom
Flashed new Gapps (failed)
Flashed kernal patch (for trinity)
Flashed Kernal
Flashed SU
Rebooted
When I booted phone prompted to enter "Enter password to decrypt storage" it is telling me that it is the wrong password. I've never had any issues until today that I flashed 4.4. I know it is the correct password. I tried going back into TWRP and when I am prompted to enter the password, it says Failed and I am unable to see my files.
Can someone guide me as to how to correct this hiccup?
TIA
Does anyone know how to at least be able to extract the files?!?! I am desperate

How to unencrypt with no booting ROM installed

I hade AICP installed on my N910f Note 4 and had encrypted it. I found that I could not update my ROM or really flash anything. I tried updating to the latest TWRP reading there may be support for encrypted phones but never got a password prompt. I tried to flash the stock rom with odin hoping if I could load that, samsung has an easy decrypt button but after flashing the german and romanian versions the phone wouldnt boot. Now I am stuck with an encrypted phone with no ROM installed that's bootable. How can I unencrypt it? At this point I would deal with it being encrypted just to get it booting again.
I will point out that my first flash of the stock german ROM worked and it was asking me for a password in German and I thought it wanted my pin to decrypt and it didn't work. I later read that it may have been asking for my google account password which I could provide except now I can't get it to boot after reflashing it a few times. If anyone knows of a way to get a ROM to flash and boot then that would be great or a recovery that works with encrypted phones so I can enter my pin to decrypt it and then simply flash a ROM zip file.
This turned out to be really simple. Flashing the German stock rom worked. It also unencrypted my phone. The problem I was having with the flash was with a custom ROM you need to go back and do a factory reset after the stock ROM flash, then reboot. After that it booted and I was able to flash TWRP with odin and flash my AICP zip, do a titanium restore and all is well.

TWRP Encryption password

Hey guys,
I recently flashed to cm13 from the Android N Developer Preview and I formatted the userdata partition in order to decrypt the phone afterwards so TWRP could access /data but each time I boot up it's reencrypted. Any thoughts? I can't use TWRP at all to install zips or anything like that while the device is encrypted - it requires a password to decrypt /data. I've tried default_password, my pin, and rebooting before setting a password and none have worked. Please help I'm slowly dying without xposed. Also I'm not coming straight from the Android N Preview; I downgraded to M in order to get the right vendor image via the OTA update because when I tried to flash cm straight from the preview I got in a boot loop due to not having the right vendor.img if that makes any difference.

You have to flash a modified boot img. The official one automatically encrypts your phone.
Where would I find one? I found one but it just put me in a boot loop. Is there a thread for that on here or any good places you know of?
If flashing zips is the only thing you are concerned about you could give flash fire a try. It worked great for me to flash some zips in nougat.

Android 7.1.2 Encryption

Hi,
sorry if that question has been already answered, but I cannot find an clear answer
I need to encrypt my cell phone, however each time I try I get an error telling that the encryption
did not finished correctly, and my cell phone is corrupteur and need to Factory reset
Is there a 7.1.2 Rom that exists with encryption working ?
if not do you know if a 6.x Rom exist that's support encryption.
Many thanks for your help.
I finely found a way to have ZUK Z1 encrypted under 7.1.2.
Below steps used:
Factory restore using All in One tool
Flash TWRP Official 3.0.2
Using TWRP installation of a 6.0 ROM
After boot and setup, enter Preference/Security/Encrypt
At this point ZUK Z1 appears encrypted
The issues are that under TWRP unable to mount or see files
I flashed lineage and open_gapps using the “adb sideload” option.
After a reboot, ZUK Z1 appears as encrypted
For the time being all is working fine, except the fact that TWRP cannot mount the device, because it’s encrypted. I guess that’s an issue with TWRP itself. I don’t know if a version exists to fix this ….
I tried to do it same way with several 6.0 ROMs still available here (a lot of dead links...) but each try using device encryption ends with an
automatic reboot and back to welcome screen without encryption.
At the moment I am using TWRP 3.1.0 (comming fomr 3.0.2) with 7.1.2 Nuclear ROM.
Any ideas? Device Encryption is important for me.

The 6.0 ROM that's worked for me was " Temasek-20160217-NIGHTLY-ham "
Make sure you fully factor restore using the All In One tool
boot your phone on V5 and setup your cell phone account
Then using TWRP install V6 ROM with the Temasek one.
then Encrypt your phone .... that's should work ok
then us "adb sideload" to inject the V7 Lineage ROM
Let me know at which step you are stuck !
Hey, sorry for long delay ...
It will work up to "Temasek-20160217-NIGHTLY-ham", flashing AOSP 4.6 (Android 7) by sideload will cause "Password wrong" problems while booting
decrypting data partition. Still hope to get a way working zu install AOSP 5.1 (Android 8.1) with full encryption. Tried TWRP 3.02 and newer 3..2.1.
no worry about "password", I already installed nightly build of Lineage without issues using sideload.
Of course I got the message about password, I just ignore it
the only point is that I had to install TWRP V2.8.7 and not 3.x. because with 3.x sometimes I was not able
to boot recovery mode.
Before each install I fully backup my cell phone in case of .... SMS, Pictures etc...
Good luck,
The problem is not the password while starting to recovery 3.x.x, its the password while booting...
1. Factory restore using All in One tool (okay, works)
2. Setup Phone and encrypt (works, okay - Password will be accepted)
3. Flash TWRP (3.02 / 3.2.1.0) - tried both (okay, works - Password for encryption Recovery will not be accepted
4. I skip that and sideload flash (clearing cache etc.) "Temasek-20160217-NIGHTLY-ham.zip" (okay, Recovery = not, While Booting = Password accepted) (I choosed PIN and something like : OfferMe#1963ZU several times)
5. I skip Password in Recovery and sideload flash (clearing cache) "lineage-14.1-20180124-nightly-ham-signed.zip" (okay, Recovery still not, While Booting = Password NOT accepted)
Seems no matter if Lineage ROM 14.1 or higher...
Still confused
I am not using password at boot. I only set a password to unlock the phone after boot.

When, entering TWRP, it asks you for PIN/password.
You have to enter your pin/password you have defined in Android for unlocking the screen.
TWRP must then confirm that it successfully decrypted for user 0 (for user 999 it would fail, do not wory about)
This is really nothing new, but you must not use an outdated TWRP that does not ask or does not support it properly
If having problems, reboot to Android and reset your pin/password.
Some TWRP versions may not support properly if you use pattern in Android - hence better switch to pin.
However, if you cannot make it with pin, reboot again to Android, redefine to pattern and try

Make sure you use the latest official TWRP for davinci
Which "notifications" - it's about Passwords and Security in Android. You can try by removing Android unlock pin/pass, reboot to Android and set it again and then try with TWRP.
Again, make sure you use up-to-date TWRP, best the official
twrp-3.5.2_9-0-davinci.img (if you were not familiar with and TWRP does not ask, maybe you are on an ancient and maybe some unofficial TWRP)
HI, I updated to V12.1.4.0.RFJMIXM and tried to install the latest TWRP but booting into recovery mode TWRP is in this like read only mode and dosnt bring up the usual thing to decrypt your files. It says unmodified system partition. Keep system read only? TWRP can leave your system partition unmodified to make it easier for you to take official updates. TWRP will be unable to prevent the stock ROM from replacing TWRP and will not offer to root your device. Then it says keep read only or swipe to allow modifications. Any suggestions? Tried removing and adding security pin but didnt work
I need it to install magisk. I tried patching a recovery image with magisk which worked. But trying to boot to magisk with recovery dosnt work. I hold the keys and then when it vibrates let go but it always goes to stock recovery. Not system with magisk as it talks about.

This seems like a bootloop. Did you change any roms before this happened? You might have to format (not wipe) your data partition which unfortunately will also delete all your files from the phone's internal storage.
