Persistent rooting

Post by witom » Thu May 19, 2016 8:57 am

For a long time now I has rooted my Samsung TV using the public Method by installing the Skype App and install SamyGo Extensions Widget.
This allowed me to have a rooted TV without have to have a inserted USB Stick. So I was able to use extensions like oscam on this TV without having a USB Stick in the USB Slot and this was also available after TV restart.

Since a few days my TV was hanging after some time (under one minute) so I decided to reset my TV by using the Factory Reset method.
After the factory reset I rooted my tv again using the donated way (viewtopic.php?f=63&t=7982).
Also I installed oscam using the tanjasoft way. This also was working and the oscam extension was available again.

But: This method is only working as long as my USB Stick is inserted to my TV.
If I remove the USB-Stick and restart the TV no telnet or ftp access is avaliable. Also oscam is not started and not available.

Is there a way to make this "root" persistent without to have a USB Stick inserted?

My Samsung TV is UE22F5480 with MST Firmware version 1119.

Regards,
Tom

Thank you for this information. I will try this at home.
Does this mean the "donated way" does not include a permanent way to root the device so I always have to first use the Skype root method and second replace this root with the transition?

No, it just means that "donated way" mandatorily requires a permanently plugged USB by design, in the opposite of Skype/transition. All methods are equally "persistent", It's only a matter of "where are root files", USB being safer since you just have to unplug it in case something goes wrong (e.g. in your case: factory reset, setup everything, etc... instead of simply: format USB).

Thank you so much for your help!
Do you know a "real" factory reset method for my TV? I had used the method with the key combination
[MENU][MUTE][POWER] to get access to the support menu and used the Factory Reset under Options.
But after restarting the TV the initial setup was shown as it would be resetted but the smart hub setting to enable the "developer" account is disabled in the menu option and if I start the smarthub and go to find more apps I can use the "ip setting" option as I know only when the developer account is enabled...

also there was the previous installed SamyGo_F entry shown in available addons...

In addition to factory reset (which only restore NVRAM defaults) you can do a Smarthub reset, TV should be *almost* clean then.

Do you mean the option in the menu for smarthub?
If yes I tried this also...

Well, no need to be obsessed by cleanliness, if your TV stopped to crash that's enough :)

My problem why I ask for is that if I reset the device by factory reset and also reset Smart Hub I only have the Browser Addon installed and available...

My Steps described:

1. Reset using Support Menu

2. Smart Hub after factory reset and initial setup was done

3. Trying to go to more apps
