Hi, do you have any news about root or firmware downgrade for J samsung tv on firmware 1490 with blocked updates on router? :)
Yes, but a lot of work on my head :) For now I have good news for H users with blocked updates on router :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 !!!!
