I have a Samsung F8500 with recent mainboard change and currently with firmware 1114 (FXPDEUC).
All widgets are functioning but HBO GO. Samsung support would like to upgrade the firmware to the latest. Me not

1. My question to you is if you know what is the minimum firmware version to run HBO GO?
The application is starting then I am blocked at a logo of HGO GO without arriving to point of login.
2. Now I have root with samygo (thank you for this!). The next firmware ver that I found is 1135. If I upgrade to 1135 I will lose the root or any access in extended service menu?
History of actions:
I have already done the reset of country, reset of hub, change of country (to erase all widgets), factory reset from extended service menu, repeat again change of country (to erase all widgets). All done without and with root.
Unblock the updates in router, temporary.
Now I have root with samygo and blocked the updates in router and in service menu.
