Hi, I have an i9505 which I have rooted with the help of some of the guides on here.
Anyway, I encrypted my phone from settings -> security not really knowing what I was doing. I was just thinking that it would make my phone more secure or whatever.
Anyway, following this I now have to enter a password every time I lock my phone screen which I find very inconvenient and I understand that I can't install any custom roms in the future.
I have tried to decrypt the phone from settings -> security but the process doesn't seem to complete.
It says that the decrypting process is irreversible ect ect.. it will take one hour ect... ect.. then when I click to confirm it and begin the decryption process the phone just seems to switch off then it turns back on by itself within 30-60 seconds and that is it. The phone is still encrypted?
Can anyone help me please?
I am really gutted!!!
Thanks
I am experiencing the same problem right now, did you ever find a solution?

I was keeping my hopes going because there is a "decrypt device" option in the security settings, but that wouldn't work and I was hoping I was ****ing it up somehow. Guess device cleansing is my only option.

Samsung device have the "decrypt device" option and it works, tried it multiple times.
Decrypting a Samsung Galaxy S4
Had the same problem several times. Make sure "USB Debugging" is off in the "Developer Options" section of the Settings screen.
Dont fret....go to settings<lock screen and then change it to swipe....Hope this works!

Last night i had the same problem but i managed to fix
If you press decode it says password and then enter a password of at least 6 digits AND AT LEAST 1 NUMBER to activate the decoding part i tottaly missed that but i realized it a few hours after.
And then it started decoding for about half an hour and it was fixed.
Hope this was usefull so you wont need a system reset.
Given that the original post was in 2013, the OP likely had to reset, if none of the other posts from 2013 in the thread helped.
4.1/2 years on - there must be someone out there that knows how to decrypt the GT-I9195 ??
I spent yesterday researching pro's & con's of encrypting my phone. Couldn't find anyone saying password had to be entered EVERY TIME I USE the phone, just people wrongly advising that I would have to enter password every time I switch the phone on. I could live with that, I thought, so I encrypted it. Big mistake. Why anyone wants a phone that needs a password on every use, I do not know.
Please help me decrypt my phone. Thanks
Hi,
I have a N910C Exynos (oem) on Lollipop and i´m tryning to wipe my credentials but in the Security options the "Clear credentials" option is disabled/grayed out. How can i turn this option on??
Explain and Things that i already tried:
Problem starts after i tried to root my galaxy. It was already in 5.1.1 (OTA installed) and when i tried to root i got a boot loop.
- I did the factory reset wiping cache and data/factory reset and still got on boot loop
- Tried to return to original condition installing by Odin the 4.4.4 stock version but got sw rev check fail .... 2 binary 1 on android screen and Fail status in Odin
- Tried to install 5.0.1 and same thing
- Installed 5.1.1 normal.
- After boot up, Clear credentials (as some other features, like lock screen) was already grayed out
- Tried to do a downgrade and Fail
- Tried to do the encrypt and decrypt the SD card, but same thing
- Tried to unlock screen with samsung find my phone, change to pattern mode, choose a pin code after pattern, reboot, put the wrong pattern on porpouse but it never ask for the pin so i could try to use google account to reset
- Tried to uncheck and check every admin
I tried pretty much everything that everyone write on this forum and internet. Nothing seems to work.
Is there any third part app to clear credentials or anyone has any idea how can i fix this F#[email protected]# problem??
Plz, Help

When the clear credential is grayed out means there aren't any credentials to wipe. Basically, what is your problem?

In Security section some options are grayed out with this status "disabled by administrator, encryption policy, or credential storage"
The Encrypt device option have only Pin and fingerprint on, the rest is disabled... I saw that if i clear the credentials it would fix this problem...

So, try to explain better your issue via posting some screenshot or writing more clearly.
Do you mean the Screen Lock Type?
-from Lock screen and security > Screen Lock Type
I think you previously encrypted your device and now you are having issues, have you tried to get access to your old files?

I´m new here, can´t post any links to my photos. Sorry if i´m not been clear, my english is not that good. I´m from Brazil. But i will try to explain more clearly here:
1 - I go to the Settings > System > Security
2 - In Security tab i choose Encrypt device (codificar dispositivo)
3 - Then i click to choose the lock screen option
4 - The 3 options are grayed out, just the PIN (senha) and Fingerprint (Impressão Digital) are enabled
I just got the phone. Brand new. Then i tried to root but got stock in boot loop, so i installed the stock rom and then i saw this problem.
I have never encrypted the phone nor the SD. I can access everything in my phone but this options. Knox are diabled to, since i tried to root and got Knox status 1.
The only way to highlight the 5 screen lock options is if i go to samsung find my phone, click in unlock screen device. Then the phone gets unlocked and i got a pop up to choose a new screen lock. But if i choose, for an example, Pattern, i draw the pattern, choose a pin code, but as soon i finish it all options get grayed again.
And in the lock screen i can draw the wrong pattern as many times as i want but i don´t got the option to use de PIN to get into device.

Ok, the path is a a little bit different for me. I´m in the Security -> Trusted Credentials... Here i can see 2 tabs: System and User
In system there ar a lot of credentials and they are all enabled, in user i have none.
Just a heads up: I already tried to disable all of them one by one before. Didn´t help
Did you ever get this figured out? I have tons of certificates installed and turned on. Some are from China, Turkey and in other languages. I want to remove them all but Clear Credentials is greyed out. I'm using a Samsung S5 on v6.0.1 (not rooted).

Hello all,
Although not clearly encrypted upon receipt of the device from VZW, I located the setting and encrypted the device.
After the last security update from Google/VZW I noticed that the option to encrypt/decrypt device is no longer present, and after rebooting my phone, I am no longer prompted to enter my PIN at boot. Note that I did have the setting as discussed/shown here and here after receiving the device.
The explicit feature I'm speaking of is discussed in this review:
Samsung now supports the PIN to decrypt on boot feature. It must be enabled manually in the lock screen and security settings area under “protect encrypted data.” Also, the S7 and S7 edge are full-disk encrypted by default, and cannot be decrypted.
Click to expand...

These two things lead me to believe that the "whole-disk" encryption on the device has been removed completely or... is it just the PIN on boot feature? What does it all mean? What is the world coming to?
Am I just paranoid/silly and just forgot where the option was? Or is there a vast global network of government organizations trying to get my cat pictures?
Thanks,
Matt

One thing I can tell you for sure...based on a diff Samsung device: would WOULD KNOW if it got decrypted somehow as it factory defaults the phone.
Could be just different behavior regarding the PIN or even a bug.
Hello, i activated just for test screen lock pattern. Now i cant go back to none screen lock, the option is grey( Disabled by administrator, encryption policy or credential storage), i only can choose between pattern, pin code or password. I try all methods find on internet wich work for other phone ex samsung with android 6.0, no one works on huawei p8 lite android 6.0.
Any ideas?
Thank you!
Go to Settings-->Advanced-->Security-->Select Clear credentials and click Yes
I all ready did this, and multiple reboot, the option is still grey
Print screen
Is your phone encrypted?
Sent from my Huawei P8 using XDA Labs
No, is not encrypted, sould I try to encrypted, and decrypted, may be will work this way?
Try this
Go to Settings-->Advanced-->Security-->Device administrators and disable all of them
Sent from my Huawei P8 using XDA Labs
I try evrything I find on internet and is not working, there is anybody with the same problem with p8 lite?
Im also facing the same issue.. please post if you found some solution
Exact same issue here
I found a way to "cheat" it
Set code to pattern->get pattern wrong 5 times -> password now removed
Would like to see a permanent fix though
Or AOSP lockscreen lol
Thank you very much, is working for me, the option "none" is still grey, thank you again
I have android 6.0 and i face the same problem. Any fix yet?
huawei p8 lite, android 6, screen lock problem
I activated PIN screen lock for testing VPN, yesterday in the morning, and after that I was not able to remove it. The only thing that worked for me was setting pattern and backup PIN, and to make wrong pattern five times, as someone before suggested. Option none is still "grey" but at least I do not have any more screen lock of any kind. Thank you very much. :good:
your post saved me from going totally nuts!
Just to say thank you!

I've searched whole the net and found nothing. Your cheat worked, and I've just signed up in XDA to thank you. :victory::victory::victory:
After using a wrong pattern several times (it took well over 5), it says "Try again in 30 seconds". Grr…
It's a P8 Lite running Android 6.0 as the latest firmware (…B584).
1)opt for screenlock>back pin password
2)now try wrong pattern in screenlock till it comes for FORGET THE PASSWORD
3)now go for back up pin
4)now you will get an option to select screenlock.now also NONE optionwill be grey
5)don't opt anything that and press back
6)after this screen lock option becomes automatically NONE,even without any selection(go to settings and check it)

your the bast ....worked with me to huawei y6 ii :good:
just registered in dxa

Hi,
As most devices running Android 5.0 and newer are encrypted by default, this might be the cause that you are unable to remove the lockscreen protection. It uses a locally stored and randomly generated key until a lockscreen protection method is enabled, then switches to this as the encryption key.
If disabling the device managers and erasing the Certificates do not allow you to remove the lockscreen protection, there is an option under Developer options> Screen lock. Disabling this will remove any lockscreen protection that is in place. If this is also grayed out the only option is to perform a full factory reset of the device (including internal storage wipe) in order to reset the encryption key.
Cheers
Hi everyone,
I have oneplus 6t however i am not able to find the setting for secure startup where as it asks for pin when you reboot the phone
Thanks
There is no direct setting available, it's asked when you set the security settings. You have to remove all security settings and set them again to have the option proposed

Hi,
I have tired to remove all security and re-add but still don't get the option on Oneplus 6T. OxygenOS: 9.0.7.
Do i need to wipe the phone and start again ?
Any advise would be great.
Thanks
Abid
I was looking for this as well. Didn't see it on setup nor in the security settings.

My phone always asks for pin/pattern to unlock the phone when it is rebooted.
It wont even let me access the camera from the lock screen until I enter my pin/pattern the first time after boot. I think this may be because the phone does not decrypt until the pin/pattern is entered that first time after boot.
I found this while doing a little digging. Its for the O5 but same for the 6T
"OnePlus support responded to me on this.
The answer is "YES", OnePlus 5 / OxygenOS 4.5.x DOES use the new File Based Encryption and Direct Boot.
So there CANNOT BE a "require PIN at boot" option.

Ok, I'm confused...might be because it's first thing on a Monday morning, the caffeine hasn't kicked in, it's New Years Eve, but my phone REQUIREDS a PIN on reboot...it's how I set it up when I first set up the phone, with the fingerprint sensor.

I was confused at first but basically "Secure Startup" means the phone does not boot past the boot loader without entering the pin (from what I understand).

With file based encryption you normally don't get the option. I didn't have it on my Essential either.
