Re: Firmware downgrade for UE32J5600AK

Post by ITCertified2006 »

Hi All

Have a UE32J5600AK with firmware version 1520 - would like to downgrade if possible.

Could anyone recommend or advise if this is possible, did download HKMFDEUC to FAT32 Flash, but TV says no update available.

Thank You.

Ok I bought a UN65JS8500 (2015 model) and I love it. It's my first smart tv and I knew nothing about these firmware updates. I now have noticed that the 3D and overall performance of the tv Sucks since factory firmware has been upgraded from OTA updates. All I want to do is reset the firmware to what it was to when I first turned it on. The tv says its on v1530 as of today 2018/05/04. I now have auto update turned off. At one point last year, I thought someone hacked into it. Not even confident to have it connected to internet anymore. In the maintenance menu, should the screen type match the model/size? Mine does not. Its completely different.

I'm a pc tech but new to working on tv's. If I could get some guidance on how to just flash the Rom back to factory I would really appreciate it. The tv should store a master copy as a backup correct? Or do I have to download the version, I think it was 1401, don't quote me on that.
TIA.

I've been searching and digging into all around this forum since days and hours here.. It seems, seriously, A LOT OF people who have Samsung J serie TVs, need downgrade&oscam.. Sadly, no solution at all, it seems.. Would anyone be a solution to all of us here?

I'm willing to pay/donate here to find a solution to have oscam installed in my TV:
Samsung UE40J6270
Firmware: T-HKMFDEUC-1530.1

Yes, I blocked the updates..but it seems I'm too late..*sighs.

Yes
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"!!!

Hi,
I have a Samsung j5500 TV and unfortunately I have the fw 1550 and I can no longer use the WI-FI connection and therefore the Smart function. You said something will come like fw0000 but who is working on this? thanks
