Hi,
I have CM10 running on my rooted Galaxy Nexus and I just enabled the disk encryption. However, I can't find any options what happens after a few failed attempts? I would like to reset and wipe my phone so that it will be usable, but without any of my data. Cerberus is flashed, so I think I'll have a better chance at recovering my phone if it's usable and not completely locked.
I have set a profile with tasker + secure settings to shutdown after 3 failed PIN attempts (which is different than the encryption password), so I should be save there and a thief would be forced to guess my much safer encryption password.
I know that I can do it with cerberus, but only manually.
Bonus point: Is there any possibility to use a pattern instead of a PIN for the display lock? It's unavailable after encrypting..
Nobody?
Hi,
I just bought Samsung Galaxy Note 3 and want to setup it like my old Galaxy Nexus. Also I want to stay with fully stock ROM for a while so I need to perform everything without root.
I need encryption set on my phone. Problem was that for some reason Samsung ROM does not allow PIN unlock on encrypted device. Password wasn't convenient so I searched for workaround for this.
Solution was to install Tasker+Secure Settings and change lock type to PIN just once. Everything was perfect, PIN lock was set permanently. BUT, when I rebooted the phone I wasn't able to decrypt storage with old password. My device can be only decrypted with new PIN now.
How the hell that could be? I believed that when I set encryption password it will be used for decryption. Obviously for me now, it's not.
My question is: what encryption key is used for data decryption in Android? You can change password or PIN and decrypt device with it easily. In other words: what data (encryption key) should be hacked in order to decrypt the phone and where is it?
I completely removed Google Keyboard from stock rom (Moto X Play, 6.0.1) and installed Hacker's Keyboard instead. Everything works fine, but when phone boots and the screen appears where you have to enter the password to decrypt the device no keyboard is present on screen. I can go around it with USB OTG and physical PC keyboard but this is not something I can do anytime as I don't carry the keyboard with me. Is there any way to use custom keyboard to decrypt the phone or is it somehow set to work with Google keyboard only? Hacker's Keyboard is installed in /system/app if that matters. TIA
Hey Friends,
My S7 edge had a problem with the charging port and I sent it in for an exchange device today.
Previsouly I had Nougat installed so the device was KNOX Void and Rooted.
I read that If you want to ensure that noone can restore the Data from the Device (Online Banking records, passwords, images) you have to encrypt the device and then do a factory reset.
Unfortunately encryption did not work on Nougat (it would show the encryption icon and then reboot)
So I basically flashed the Stock Firmware of the Provider (4 Parts) (6.01) with Odin and hoped that I can find the encryption option in the Security Settings Menu but it wasn't there. I could only encrypt the SD card.
My question: Was the device encrypted as soon as flashed the stock firmware or was encryption simply unavailable on the stock rom?
I did multiple factory resets and also Installed an app to "delete empty space" which should overwrite any data that might hide in the free space.
I am worried that whoever gets the device next might be able to restore my banking data, images and e-mails.
What's your take on this?
Best,

I have a Moto Z with stock image, Magisk Root and Turbo Z Custom Kernel.
As far as I see everything is fine except two one things:
1. Sometimes downloads aren't starting at all. Which is very weird because regular surfing with Chrome works flawlessly. But if I want to watch a video from YouTube (regardless whether YouTube app or within Chrome) the video won't play sometimes. The same happens with F-Droid downloads. Sometimes an installation/updated doesn't even start the download. The network is fine (it works perfectly with any other device).
2. I have a screenlock set up but I don't think there is encryption active. I have to type the password just once (device boots to GUI then SIM pin, then unlock PIN). On encryption the unlock PIN have to be entered bevore booting into the GUI — right? However, Security Settings claims that the phone is encrypted. I wanted to set / change the password with cryptfs password manager but the app doesn't even start claiming 'cannot get superuser access' (maybe it's not compatible to Magisk?). Is it possible to change/set the password in this state without risking data loss?
The stock kernel enforces encryption, the z-kernel doesen't. However, your stock kernel already did its deeds. So if you really want to remove encryption, here is what you might want to do:
Remove all phone passwords (pin/password/pattern etc), then make a backup of everything. (If you don't & then restore such a backup, you'll always end up with password/pin/pattern mismatch).
Then boot into TWRP recovery and format(!) data partiton (erase just doesn't cut it..). If there's still a problem, change data's filesystem to ext4 and then back to f2fs - that should remove any nasty residual settings.
Then reboot & enjoy. Maybe you can restore the backed-up data files to the unencrypted partition now, but I wouldn't bet on it...
Hi again @benzinerwin
However, I don't want to remove encryption. I want to enable it.
It says that it is enabled in settings but I strongly doubt that it actually is.
Just change the password, opt for boot password (or whatever it's called), boot into TWRP and see if it asks for password/pattern to unlock access to the data partition...
If you cannot get there, just do the above, end up with an unencrypted data partition and the go through the settings and trigger the encryption with boot pass etc...

Click to expand...
Click to collapse
That was it
In retrospective this is pretty obvious. Thank you.
Now just the problem with the struggling downloads is left.
Hmm, about the strange download problem... that pretty much sounds like an app not having all the requested rights (look through all the settings, not just the app's properties... [sigh])
But it affects all apps. Even Chrome. Regular surfing is fine but for example loading a YouTube file sometimes doesn't even start.
