I have a HTC HD2 and recently I had to reset my phone due to having an issue with it and yet I had the encryption enabled on the storage card, and was not able to decrypt it. Now when I put the storage card in my phone,  and now it can't access any of the file that were encrypted on it. All of the file extensions have been changed to .menc (Microsoft Windows Mobile Encrypted) .I understand that the only "real" way to decrypt it was to use the phone's key to do it, but to my understanding, once the phone has been reset it looses the key to decrypt the file

My question is, does anyone know a safe way to decrypt the files or a program that would assist me in doing this?

I just contacted HTC Customer Service and was advised that they didn't know how to decrypt .menc files. The rep told me once i had to reset the phone, the encryption key was losted. I then told him that the only reason I had to reset the phone is because of the issues I was having with it and was told to do so by Tmobile. This is crap.... It really sucks. You mean to to me you one who how to decrypt these file at HTC. Crazy. Please someone HELP!!!!!

Mate,

i'm sorry to tell you that you lost your files.

That's not HTCs fault but yours.

a) HTC is just giving you Windows Mobile. But they hardly can change its features. The whole encryption thing is Windows Mobile, not HTC.

b) you used a technology (SD-card enryption) that you don't understand to its full extends

If you want to continue using this encryption buy SPB backup (www.spbsoftwarehouse.com/.../backup ) 25$. This software is capable to restore the encryption keys even after a device change. That means: Whatever happens (hard reset, ROM upgrade, even getting a totally different device) you keep access to your menc-ed files.

Plz read what I have replied to in the form "How to decrypt encrypted items on SD card" because this is the same thing......

Decypting the .menc file is very easy, just follow these instructions !  :-)

Let's say you configured your phone to "encrypt" all data on the "micro SD storage card". This setting is in "System", then "Encryption" screen on the phone.

Now, all files, pictures , movies taken on the phone and stored on the SD card are now encrypted and can only be viewed on the phone. When you hook the phone up to a computer and try to copy/download the files from the phone's SD card, they have a .menc file type attached to the file.  Doh, the computer can't read the file!  Not to fear.

Simply clear the setting above to non-encrypted. (Warning, if your phone is lost, people can steal your files, beware!).

Now select and copy all of the files from the directory (pictures, movies, documents, whatever) and paste in the "PHONE" memory....not the microSD card memory. This process has several step process.

If there are multiple folders you need to copy and unencrypt, then you need to repeat this process over and over.

(1) select and copy all the files on the SD card in the directory/folder you want to unencrypt

(2) unplug the USB cable from the phone from the laptop/computer

(3) go to the phone memory, and choose a folder where you want to paste (eg. pictures, videos)

(4) paste the files

(5) files are now in phone memory

(6) unplug USB cable

(7) select and copy files you need unencrypted from phone memory

(8) paste back into microSD memory folder

(9) plug USB cable back into computer

(10) copy any files you wish now onto your computer

Easy , eh?  :-)

It works, I did it, and wanted to share the solution.  Good luck!!!

flahertymiguel.. I tried the following steps that you suggested and that doesn't work. I am going to just have to accept the fact that the files in question are lost.

....his steps describe what to do when your device is still fully funczional.

Not what to do after a reset...

regards

the webpage www.roflspace.com claims to have a menc file decryptor that works on an htc HD2, though i am waiting for my registration to clear before i can verify that the file exists

That website doesn't work.......anything else?

flagertymiguel - - I'm trying to follow your instructions to decrypt my files but am getting a little confused.  Between (2) and (5) you mention to unplug the USB cable, but not when to plug it in again.  Also, the operation copy-paste, is it done on the computer or the device?  Can you clarify?  I also want to recover some important files and your help would be certainly appreciated.  I'm with T-Mobile.
