Guys i know this is not the correct place but someone can please tell me "what to do if i have lost my password" ??
I am using Windows 7
Laptop of Sony Vaio
Please someone help
I know that this could possibly be used malicously but if you can access another computer, download OphCrack and burn it to a CD or write it to a USB drive and you can use that to recover your password. I've used it multiple times on Windows Installations for friends who forgot their passwords on their home computers, it does work. xD

simply download the ISO, burn it to disc and then boot it, it will have the utility for recovering the password. Three are hundreds of tutorials on how to recover your password with OphCrack

I use a program called Kon-Boot, its good enough for most tasks, it wont help if your part of a domain, it also wont help if you have encrypted any drives or folders.
it wont tell you the password
so how does it work?
well, the short answer is that it hijacks the boot sequence and bypasses the password check, you just click on the user and ignore the password, once your in you can change your password or a safer option is to add another admin account, then log in to that and change your password. The problem is if you encrypted anything, then im afraid to say your ****ed!
you see the encryption key is part made up by your actual password, so by using my method to change the password, what you will end up with is data still encrypted on your old password.
the ethical uses of this are limited, but there are uses which is why im happy to share it, just don't **** around if for any reason some data is encrypted and the password is likely to "turn up" again because once you've opened this bag of worms you cant go back so essentially the data will "vanish"

Password would be gone, but so would days. http://unetbootin.sourceforge.com use that to copy the ISO to your flash drive.

Android 3+ has a nice feature -- device encryption. You can encrypt the contents of your device with a password, and after that this password must be entered during device boot, otherwise the data is permanently lost.
The bad thing is that this password is set to the screen lock PIN / password. So you either set a short password or PIN, that you can enter quickly each time you unlock your phone from sleep (but this provides weak encryption), or set a long password and have to type it 20-30 times during the day.
This stupid behavior may be fixed easily. Android provides command-line tool called 'vdc', an interface to Android Volume Manager. As written in "Notes on the implementation of encryption in Android 3.0" [1], it has a command 'cryptfs changepw', that allows changing encryption password. Of course this command must be executed as root.
vdc has some other commands related to encryption, one of them is 'cryptfs verifypw', that allows to validate the supplied password.
I'm currently writing an application that will assist user with changing encryption password. This is my first public application for Android. You can find a source code on GitHub [2]. It is very simple, but maybe android gurus here may find what to make better.
Comments and pull requests are welcome
Thanks!

Sorry im noob
What will change visualy?
Or screenshot?

Thank you for this. I wanted a more simple password for the unlock, but a longer more complicated password for the decryption. You should put it on the market and charge $.99USD (or equivalent in your currency) as it's quite useful. I'd buy it
Thank you!
Actually I have registered myself as Google Play Developer, now I'm waiting for approval. As soon as my registration is approved, I will update this thread
Although I'm going to make a free and donate versions, because I believe that will help to make Android better, and people who want to say "Thank you" will buy Donate version anyway

Nothing will change visually, hence no screenshot. What's important is that you may set strong password for decrypting the internal storage, but keep using simple password (or PIN) to unlock the screen.
P.S. I have verified that my app works on Jelly Bean too.
I have finally published an application on Google Play! Currently there is a free version, Donate version will come a bit later
The link is: https:// play.google.com/store/apps/details?id=com.kibab.android.EncPassChanger
Enjoy!
Thanks for that app, that is also what annoyed me
Thanks for this. I've been trying to work out why encryption wont work on any ROM on my HOX (dies with unable to get size of block device cryptfs), and you have given me a good lead to investigate with vdc. Information on encryption in android is sparse, and almost all threads here on XDA get no replies.
Thanks again.
I've been tempted to use device encryption recently, but there is a distinct lack of information about it, particularly on custom ROMs...
Might need to give it a go, just the lack of backup abilities might be an issue...

I use CM10 on the Galaxy Nexus (maguro). Encrypted. Actually, only /data is encrypted. /system stays unencrypted. And this App works as described.
For Backup use TWRP. It asks for your password to decrypt storage.
You can then backup, restore, flash, install whole ROMs, wipe and what not.

btw. The encrypted /data partition lets you have two boot animations, one that is shown before code has been entered (the one in /system/media) and one after the correct code entry (the one in /data/local).

Hmm... I have i9100 (S2), so I would need to see about putting TWRP onto it...
Yeah, only data and SD are encrypted... Can TWRP cope with encrypted SD btw?
Great, it's easier than to change on command line
This should just be default android behavior

Yes, SD is encrypted too. And TWRP can only read from it after correct code entry. Don't know about the external SD though (since the Galaxy Nexus doesn0t have one).

Wish I had a second phone, then I could just research this
Quite awesome. Now, can I use a strong password for encryption and then pattern lock for normal day to day use? That would be my ideal situation. I heart pattern lock!
Just trying to clarify how this works... so you keep your normal 'short' pin unlock code for unlocking the screen, but set a long code for decryption, and this code will only be requested once per boot, during bootup? Is this correct?
Thanks
How it works
Yes Sir. You are correct.

Unfortunately it's not possible to use pattern lock while using device encryption, Android forbids it. Patching Android framework will help, but this is completely another story and possible suggestion for ROM makers such as Cyanogenmod.
Is the 16 character Android limitation present, when using this tool? I currently use a 16 character device encryption/unlock pass phrase. I'd like to strengthen the device pass phrase some more.
I don't know if this is even possible during the device boot sequence, but being able to use a Yubikey with an OTG cable would be awesome!

Afternoon,
I'm using Exchange AcitveSync Policies (EAS) to encrypt our new WP8 devices for work. I wanted to know where the Bitlocker encryption is stored once encrypted?
And what is the process of decrypting an encrypted WP8 phone?
thanks
Without the key the phone would not be able to decrypt it's data - so I guess: yes, the key is stored on the device (presumably encrypted itself, using the users password/pin to start decryption).
As for decryption that is an interesting question. Someone will have to try it out. As far as I know there is no switch in the system to do this. One could try to remove the Exchange account from the device although I have no idea on how to even check wether it's decrypting/decrypted.

Hi everyone,
A friend of mine got a second-hand tablet Samsung 500t from one of her relatives.
She set her password, but she forgot it after a while. She asked me to help her to sort the problem out but I don't know windows RT and I don't know exactly what to do. In addition, we don't have any cd or user's manual. I tried to reset and I launched the procedure which always ended up with this message:
"Insert your windows installation or recovery media to continue".
I don't know what to do now, and, unfortunately, she hasn't got any back up.
Can anyone help me? Thank you.
Is she using a local account or a Microsoft account? If the latter, you can just reset your password the same way you would if you forgot, say, your Hotmail password. Go to https://login.live.com and follow the "forgot password" steps.
If it's a local account, that's more awkward. There are various steps (short of a full wipe) that you can do, but if you don't know the Admin password then most of the non-wipe options require things like Linux liveCD (or live flashdrive) images and forcibly resetting the password.

She is using a local account. We asked her relative, the former owner, about a Microsoft account, but he didn't know and remember anything about that.
Can you explain me more about using a Distro Linux to reset the password on the tablet?
I used a linux live many times, and I can manage it for easy tasks, but I have never used it to reset or to recover a password on a Window OS.
Thank you, Bob.
If you boot a Linux live image - probably off a flashdrive, unless you have a handy USB optical drive - it can mount the internal NTFS file system and find Security Account Manager (SAM). There are tools that will modify a SAM file to overwrite the password for a user. It's also possible for some tools to brute-force the password, though this can take a long time, or to look it up in a "rainbow table" of pre-computed password hashes (won't work for really complex passwords, though). Forcibly resetting the password will cause you to lose any data encrypted with it, which may include things like passwords the OS was storing for you.
Some stuff that can be used to try and recover passwords (or reset them): http://smallvoid.com/article/winnt-password-recovery.html
There's a bunch of others out there too. Here's another link: http://www.mydigitallife.info/reset...trator-or-user-password-with-chntpw-in-linux/

Can I simply delete the SAM file? I don't think she cares to lose any data so much.
Ok. I was wondering how I can run the usb drive on a windows rt tablet. Is there a "boot device option" like on an ordinary pc/notebook?
Thanks again?:
PS: By the way, where can I find an image of Window 8 rt if I want to totally reset the tablet and install a clear OS?
Aw crap, I can't believe this but I forgot you were talking about an RT device. Forget everything I just said; Secure Boot won't allow it to run a Linux image even if you had an ARM-based one.
Deleting the entire SAM will render the device unbootable. It's not just user account logon details stored there; every account (including the various system ones) are there. On the other hand, if you can extract the SAM somehow, another computer will be able to edit it just fine even though it comes from RT; it's a registry hive and is architecture-independent.
Total reset is probably the easiest option, if she doesn't mind the risk of losing data. It requires a device-specific image though; there should be one (recovery partition) on the tablet, but if that was removed you'll need to find one for download or get Samsung to handle it for you. The Surface RT / 2 images are available here on XDA but I don't know about any of the Samsung tablets.
Go look on the support website (or call support) for instructions on performing a factory reset of the tablet under normal circumstances. That will work if the recovery partition wasn't removed.

Ok, I understood.
Can I somehow install a Window 8.1 pro x86 on this device? It has got an Intel Atom processor, after all.
I need drivers, though.
Thanks again.
Now you say it's a x86 device while earlier it was ARM (Windows RT). Make up your mind, it can't be both!

...hmm actually I'm not sure. The tablet is not mine. I thought it had a Windows Rt OS. But since you say that it can't be an x86 device with an RT OS at same time...I need to find out what it really is. Thanks.
OK
I've finally found out what the OS is?
It's window 8 32bit.
The complete name of the tablet is:
samsung ativ smart xe500t1c-a01it
More, I have it at my home now.
Can we continue the topic?
Thanks
Then the methods GoodDayToDie mentioned in post #4 should work
ok
I fixed it by using Lazesoft recovery.
Thanks
Loss Password? All is not loss, even with the fact you can not boot from a USB stick drive with a password reset tool on it. The answer is actually quite simple with local access to the device Windows 8 is installed on. As long as you can get into recovery by using the "hold volume up" and pushing "Power" button method. You then simply picked Advance Recovery Options till you see Command Prompt in the menu and here's the link that'll take you the rest of the way below. What this does is replace Access Tools (for blind, etc) in Login Screen (lower left corner) with a Command Prompt window. Since it's in with the Root C drive, it makes it quite simple to merely change the password right there and be able to use it to log in immediately.
Thought your computer was safe from hackers locally? Think again (can only be run locally though, not remotely), but if you didn't have this option none of the free or pay4 password reset tools would work either. This is what they are actually doing and then they remove the Command Prompt window when done. Just like you will after using this very simple method. Or you need to use Windows Password Key to reset Samsung password.
Anyone ever resolve this?
A .dm file is encrypted using LG's file manager, you'd need to know the password to decrypt the files. It's part of the Gallery tool as pictured.
To see those images, you need the password or the pattern lock set when the files were originally locked. As noted on the first pic the option is there to Lock new files or view ones that are already locked, but without that password or that pattern lock, forget it, you'll pretty much never get them decrypted.

What if I remove the files factory reset the phone and move the files back in... Will that work?
In my experience, when I reset a device and then went to unlock the files, it asked me to confirm the password (didn't use the pattern lock) and then it asked me which Google account was used at the time the images were locked with that password (since I have 3 accounts in use on my devices at any given time). The Google account used to lock the files must be in use on the device to unlock them.
After I confirmed the password and chose the proper Google account, the files were unlocked for viewing and then I just unlocked them completely to copy them off the device for use elsewhere.
Hope this helps...
