[App] decrypt spm J/K/M

[zouhirzed]

so widget.license and app.tmg in the rooted tv is useless? cant be used elsewhere

[zoelechat]

It's useful if you want to decrypt to see "what's inside?", but any change cause signature/license to be wrong.

Yes i Know That.but my question is if i can auto install the app in another tv with the same model with usb userwidget method (like siptv for example) with these files if i extract them with root?
I'm getting a k serie soon so I was wondering that? Thanks

[zoelechat]

USB userwidget method never worked on K (and then). I guess definitive answer there
Though it might be possible to re-build a user widget using extracted files and install it using Tizen Studio.
But knowing J series still supported "legacy" (pre-Tizen) widgets, it might not even be compatible at all.

Last question ,how did siptv.app got theirs working with userwidget?in all tizen tv

[zoelechat]

I guess it might be allowed under such shape (tmg+license) if by luck the app was approved at some point (used to be on store)?
Basically: don't know.
My question is why won't you install it that way then?

[zouhirzed]

Well you see I don't have the tv yet (k) it's on the way, and I have another newer series samsung where I want try the files on.
I just want some portability with my app like ss or siptv have that's all
My other option is laptop and tizen studio ... so yeah

[zouhirzed]

I tried another method with signing wgt on a samsung backend server(usb demo packaging tool)which gave the two files but they are limited with 30 days so the app dissappear after 30 days of installation

[zoelechat]

You look more documented than me finally, not much widget stories here

Hmmm... There are no spm files for the apps I wanted to decrypt. And the existing tmg file doesn't seem to contain any source code. Just some config, icon and certficates for installing I guess...

When installing it seems some enc_<app_id>_<version>.tmg is downloaded and then installed some way - but not kept I guess.

Perhaps I can re-fetch that with wget or similar and extract and find some source code there?

Anyone knows anything about this?

EDIT: or I don't know where apps are installed.... Didn't really find it in /opt/usr/apps/ at least...
