Look here: Firmware download list for J Series

Code: Select all

(>1442) not recommended, no more possible to downgrade to previous version----
so, with 1443 you can't downgrade!

No need to pollute every thread. You can't downgrade.

Hello,
today I tried to root my UE40JU6550. Blocking upgrades on my router works since I'm still on FW 1200.
But it seems that the router also blocks SmartHub from downloading terms and conditions which I have to agree to to use SmartHub and the root app.
How can I activate SmartHub without the risk of an upgrade? Did anyone else have this problem after installing new firmware?

Let me show you 1500 Here IS problem "with downgrade", hope you see :) :D
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!
