Hola!
Just like @zimpel I have firmware T-FXP9DEUC-2221.0 and TV model is UE65F9005.
I began with doing a factory reset (through service menu) as I guessed there still might be Samygo files left from "old" root which I used on firmware T-FXP9DEUC-2006.
However, after doing this, ALL my apps are gone from the App menu, all but the Browser App and I can't access Samsung Apps to re-download them..
The "Menu--->smart features--->Samsung Account" option is greyed out, but it seems to be possible to login with developer account through "Menu--->Network--->Remote Control" instead.
I remember that this happened last time I installed Samygo as well and somehow I managed to get them back again but I can't remember how.
I have tried resetting smart hub and do factory reset multiple times but to no avail.. I have confirmed Internet connection is working and also tried to change DNS setting to 8.8.8.8.
I have searched the internet but can't find any solution that works. Do any of you guys have any idea on how to fix this?
To be honest, I don't care if I have the Apps. But perhaps they are necessary to have when installing Samygo?
Following instructions from the first Post doesn't work, the TV recognizes the USB but no Samygo App in App Menu or "More Apps" menu.
What actually did work was to use "Sammy Widgets" together with developer account and do an App Sync of SamyGO.zip. But when I run it, the info on the screen says either that it can't find any files on the usb or that Step1 and Step2 failed (or "No").
SamyGO Extensions can also be uploaded successfully with an App Sync.
Some versions of SamyGO seems to give an error referring to something like "
www.samsung.com/TVAppSecurity". I'm not sure that this happens every time or if it's random (since it worked one time).
I'm not sure which version of SamyGO i used either, I'm a bit confused after testing so many different approaches.
Is it even possible to install the new root through App sync? If so, which files do I need to have in SamyGO.zip?
I have used the NON-MST method.
