matt95 · May 4, 2013

Hello guys

this little guide will show you how to decrypt the HTC's RUUs already Unruued (sorry for the difficult language

)
in few words we will decrypt the rom.zip obtained by unruuing a RUU, if you don't know how to unruu a RUU then follow my guide here
Also this tool is made by kmdm, he is the man

! all credits goes to him.

WHAT DO I NEED?
1- Ubuntu (i'm on ubuntu 13.04 but also other Linux based distros should work)
2- rom.zip (follow the above guide if you don't have it)

HOW TO INSTALL THE TOOL
Ok guys now we are going to install the tool
Create a folder named htc_tools (if you already did it in the previous guide then you can use it)

Code:

$ mkdir htc_tools

navigate to that folder and download the source of the tool by typing

Code:

$ git clone https://github.com/kmdm/ruuveal.git

ok now we have to set up this tool

Code:

$ ./autogen.sh
$ ./configure
$ make

Allright, now you are ready to use this tool!

Code:

$ ./ruuveal --device [device code name] rom.zip (name of rom.zip decrypted).zip

for example

and now you're done

you can find the file in the ruuveal folder!

Good guide!

It can help some guys with the first look in HTC devices

matt95 · May 6, 2013

yeah, HTC has changed the encryption method with the latest HTC One RUUs so it is also needed for the Devs that are jumping onto it

./autogen.sh: line 10: autoreconf: command not found

it's my 1st time i'm kinda lost in here :/

EDIT: all good i i forgot to installl the libmcrypt-dev package that was the reason..

That's bigger than me mate

i didn't make this tool so i cannot make it available for the DHD. I'm sorry to tell this but probably you won't see this for it cause it is an outdated device nowadays...

tqf · Sep 27, 2013

well, that's unfortunate!

BUT if I open this rom.zip, get the system.img and flash it through the recovery WILL it work? what are the risks of doing this?

Nope.
1) you can't flash an image (.img) in recovery
2) There are a lot of risk, don't so this.
3) Rom.zip is the base for develop a custom rom.
You have to extract the folder with all the folder and libs from it...

OK, I see. But what if I extract and then repack the contents of system.img?
Sorry for being so pushy and/or ask stupid questions but I want to have some kind of closure of this issue.

Thanks!

When you have the rom.zip you can build a rom with the kitchen or other thing..
Which issue?

The issue is if I can flash an original HTC rom... not the entire RUU, as it contains some other stuff which I don't want to change... recovery, splash, Hboot, radio...
the reason is, when I flash a new ROM and something doesn't work or stops working, I would flash this "stock" rom and test whether the hardware works or not. I know there is Android revolution HD which is basically a stock rom, but it has also some tweaks which I'm not interested in.
Hope I'm clear about what I want to accomplish.

So there isn't any issue.
And we are totally ot here, because this thread talk about how to decrypt a ruu.
When you have the rom.zip, you have to use this kitchen and build the stock rom.

p.s. Probably the rom you flashed aren't fully compatible with the hboot/kernel that you have.
In fact, is better use the full ruu.
If you're s-off, is the better choise, because you can flash the splash screen, the hboot and other thing in 2 min

Mine is only an advice

demkantor · Sep 27, 2013

If once extracted you end up with a system.img you can flash this through fastboot just fine. You can also change the contents inside, remove and add things but it may not flash unless you are s-off.
And you can flash an image in recovery but you need to create the proper updater-script to do so.

Nice guide. I had to do it a little differently (running on Ubuntu 13.10 x64). Now if only I can find the right places in the open source to manually add K2_CL. Been reviewing the updates made on git and reviewing all the most recent changes given by dates in hopes to see what is added when support for a device has been implemented. Issue has been sent, but I'm getting impatient. Really need it for my project. :-/

What would it take to get this to work with the htc one m8? I would like to decrypt the rom.zip out of the official at&t 1.58 ruu. I have already grabbed the rom.zip out of the exe, but seeing as m8 is not listed here I was wondering if m7 or anything else might work for this. A lot of people are asking for the decrypted ruu so they can flash through fastboot. Thanks in advance for any advice.

You need to grab the ruu for that specific device and you also need to grab your devices' HBoot image. Send both to the developer and he can add support.
