[Q] Device encryption not working topic

Dears,
my device runs Lollipop and it's rooted using CF-root.

Whenever I try to encrypt it, it reboots into Samsung's logo, then reboots again without to encrypt.


Can anybody get rid of this?

Thanks!

Encryption problem... Help please topic

Hi guys I recently flashed cyanogen mod 12 on my m7 and I tried to decrypt it, After some googling I read a few times that was the way to decrypt it..

I factory reset it from the settings menu on the rom and the bootloader, Problem now is I can't access my SD card from the recovery menu etc meaning I can't restore or flash a rom to boot

I'm stuck and appreciate the help if available

Thanks.

[MOD] Flashable - Disable Force Encryption - Any Rom/Kernel topic

~~DISCLAIMER~~

Flashing roms, kernels, and mods come with NO guarantee, NONE, ZILCH, NADA . . Do NOT use this package if you do not grasp and understand this concept. You have been warned.

This is a recovery flashable that will extract your boot.img, unpack all pieces, modify fstab.shamu to disable forced encryption, repackage, and flash boot.img back to system. It does NOT actually unencrypt your device. More on that later.

Why use this? Who is this package for?

-If you are running 100% Stock Rom, but have a recovery installed and wish to unencrypt your storage. No root needed.
-Running a custom kernel you like, but it forces encryption and you want to change that.
-Currently unencrypted but want to flash a rom that uses FORCEENCRYPTION by default (cyanogenmod12).
-Just bored and want to toss the dice and see what happens.

That is pretty sweet right? Now you can flash anything and as long as you flash this afterwords, you wont have to worry about booting a rom and seeing that dreaded "Encrypting" screen anymore.

What doesn't this do?

-Well, to be blunt . . it does NOT actually UNENCRYPT your device. You will have to bite that bullet on your own, but I will offer some advice on that front later.

How to download and install?

Download - NO_FORCE_ENCRYPT_shamu_v0.1_BETA.zip

Reboot Recovery - TWRP only has been tested as working
Select "Install" and navigate to where ever you stored that file . . likely /sdcard/downloads/
Take a deep breath and wait for it to finish.
TADA . . done. Reboot and Profit!!

NOTE: If you can feel free to flash this as part of a line of other packages.

Example: You are already unencrypted and want to flash Cyanogenmod 12 (assumes you have all packages downloaded already)
-TWRP factory reset (optional but recommended when coming from another rom)
--TWRP's built in factory reset function does quite well, but if you are like me and want a clean slate . .
---TWRP>Wipe>ADVANCED WIPE> and check System, Data, Cache (will leave internal storage intact). This is recommened specifically in conjunction with switching GApps.
-Install> and select all packages at once. I recommend the following order . . Rom, then my Kernel Patcher, then SuperSU (optional), then GApps last.


That was certainly easy right? Well the truth is, unless you are already unencrypted . . nothing will be different. You will still be encrypted. Bummer right? But that is where these next steps come in. They will give you the options available to reach the fabled unencrypted status!!

Below are the only three options I know of unencrypt once you are running a patched kernel. Select one below that works for you.

~~WARNING~~

The below methods WILL erase EVERYTHING from data, including your INTERNAL STORAGE. Backup all important files, pictures, etc before proceeding. You have been told!!

-Go to Android>Settings>Backup & restore>Factory data reset
-Reboot to recovery and go to TWRP>Wipe>FORMAT DATA . . type "yes" to confirm
-Reboot to bootloader and type . .

Code:

---

fastboot erase userdata

---

Some may notice there is an experimental addon.d included. This has NOT been tested. In theory it should, but . . read the "disclaimer" at the top of this post. The idea here is to be able to flash nightlies as they roll out without having to re-apply this patch manually every time. This function is NOT supported on Stock Roms. If you try it and it works, let me know. Do NOT come yelling to me that it did not work and crying that you are now encrypted again. No whiner babies allowed.

At the core of this tool is a script build by @dk_zero-cool which can be found . . [DEV][INITRD][2013-10-25] Injector - An Android Ramdisk Injection Tool

Ultimately, this package is more his than mine. It is his magic that did the hard part, I just pointed it in the right direction.

[Q] Need Help With Encryption topic

Hello everyone, I'm sorry if there is a thread about this already, I am new to encryption and I had a few questions about. I have an LG Optimus L9 running Jellybean 4.1.2 and when I go and look under "security" there is no option for me to encrypt my phone. Do you guys know what the problem could be? Any help is appreciated!

Encryption topic

I see a ton of threads on how to disable it.. I've done that.

Now, how do I verify it worked? Is there a status somewhere that says "encrypted/decrypted" i can see to make sure I did it correctly and it took?

TWRP and Encryption? topic

So i encrypted my LG G2 running CM12. When booting into recovery i now cannot mount the /data partition and therefore i cannot flash anything. Is there any way to get TWRP to mount /data or to unencrypt a lollipop phone? Also will apps like FLashify still work?

[SOLVED] Cannot disable External SD Card Encryption under any circumstances... Why? topic

Solution at Bottom

I stupidly encrypted my SD Card. This resulted in slower startups as it always searches for errors, and notifies me that it's encrypted, plus it's slower to view, load and transfer any files associated/on the External Card.
Worst of all, for some reason I cannot disable the encryption. On my friend's phone she has the option under Settings > Security > Encrypt SD Card > Disable Encryption. I however, do not have that option and I have no idea why

Here is a picture of the screen I get instead:



I only have the option to change my screen lock type. When I go to do this and put my current password in, I get this:



All other forms of secure lock screens are disabled except for password.

I've googled around on the internet and I cannot find any answers for this problem.

I've tried:

1. Disabling everything that is set as a device administrator. Rebooting and seeing if I can disable External SD Card Encryption. > Didn't help at all.
2. Formatting the SD Card after taking the files off. > Encryption is still on and I cannot turn it off.

Whilst doing this I always made sure I had more than 80% of my battery on my phone.

Does anyone else have any ideas? It's really annoying to have to use a password all the time, it's a little excessive in addition to the huge performance hit I get when interacting with stuff on my External SD Card.

I'd happily /thank anyone who can help me out.

EDIT: I spent 3 days trying to work this out, and googling around. I then also had to put up with it for 10 days.
Simply to find that all I had to do, to get the option to disable the encryption and get all of my options for lock screens back again was just set a password WITH A NUMBER in it...
Then after that, the option to disable encryption appeared and voilá. Finally I get my fingerprint lock screen back and my External SD is Unencrypted...

How to avoid cold boot attack to break android encryption topic

Hello :)

Recently I've read about that Android encyrption can be broken using a tool called "FROST". The phone has to be cooled down and the bootloader has to be unlocked.
I'm not able to post a link to detailed information because I'm a new user, but ist very easy to find the official page about FROST on the web.

I just installed slimkat ROM on my LG g2 D802 using IOroot and AutoREC installer to get TWRP on it.
Now I would like to know: Is my bootloader unlocked after using AutoREC and how can I avoid that my phone is attacked in such a way.
Íf it's not possible I think I won't Need to encrypt ist.

Thanks for your advices :)
