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 !!!!

I have problem with downgrade to 0000 from latest 1550 firmware on js9000 (T-HKPDEUC).
From 1530 is no problem.
Does anyone have new downgrade files for 1550 FW T-HKPDEUC ?

What are you using to downgrade T-HK firmware >1480? I thought this wasn't possible, but you claim to have done it from 1530?
