Re: Firmware downgrade for J Series

It seems that firmware 1550 has many problems.
My TV has no sound for a few days. I checked the hardware and configuration and everything is fine.
Are there any possibilities to downgrade or reinstall the 1550?
Thanks!!!

I just bought a used J5500 for my son. Unfortunately it has FW 1550 (T-HKMFDEUC) :-(
I tried to downgrade to FW 0000, but TV does not recognize FW on USB. Is there any way to downgrade?

Yes, block updates on router and wait. There is new stuff coming for J series but it will NOT work on tv's with NOT blocked updates on router :)
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 !!!!

For me still version 1480 stays without blocking router. I just answered no 2 years ago when it asked in top overlay bar if I would like to install update. It lists in menu that new 1530 update is available but does not install it automatically. Seems there is eeprom setting after all which blocks update.

I was looking in the forum and I can't find how to block the updates on router. Obviously, I can do it from the TV menu. Is not the same?

When would the solution be ready? I pass coronafake without my UN48JU :(

I have several devices from these companies, and in most of them you can downgrade or at least a reinstall of the current firmware.
Your disrespect was misplaced.
