[App] ForceFirmware Back (FFB)

[nguoinhen]

Hi,

I live in Vietnam and my TV type is Samsung LA40B650T1R.
I bought this TV with the firmware T-CHEAEAC 2006.0 installed and there isn't any earlier firmware installed before.
This is a restricted firmware, so I want to revert back to an unrestricted firmware to install SamyGO apps. Unfortunately, my TV firmware isn?t supported by FFB application.
Could you please guide me which firmware I should revert back to and how to do that?
Thank you so much.

Hi, you have to use Dump maker and attach all files you get (as archive, uploaded to any online storage). Thanks

Thanks juuso for your respond.

I understand that Dump Maker is used for backing up my system partitions before hacking my TV.
But after I get full dump, how can I downgrade my TV firmware?
I cannot use FFB application because it doesn't support my TV model.
Is there another safe way to downgrade my TV firmware without using FFB application?

Thanks so much.

I have to inspect your dumps and maybe we`ll add your TV to FFB supported firmwares list?

Hi juuso,
I've a samsung LN32C350D1D tv and I updated it to sometime back to the latest firmware i.e. T-SAT4AUSHC-1008.5 (2011-05-24)
Now, is it possible to downgrade my TV's firmware ? I don't know what firmware it had before. All , I want is to enable movie playback via USB(which aint currently available).. I want to downgrade so that I can try hacking the older firmware.. Need your expert opinion on this

Thanks,
Dinesh

[Dinesh]

Oh .. so I can't downgrade it , is that right?
Hmmm.. thanks anyways

[juusso]

Hello

I need the u-boot, fnw and image files to pack the firmware for downgrading my LE32B650TW TV to version 2005 using the FFB app.

Unfortunately, when trying to download these from step 7 of post #1:

Download required images (not for CI+):
LExxB65x, LExxB75x, PSxxB65x <-- THIS IS WHAT I NEED
LNxxB65x, LNxxB75x, PNxxB850
UExxB7xxx, UExxB8xxx, UAxxB7xxx, UAxxB8xxx
UNxxB7xxx, UNxxB8xxx
PSxxB85x
Korea version of LNxxB65x/75x

I get access denied error from the server (error 403).
I have registred to the forum only 15 mins. ago... perhaps I just have to wait?

Otherwise, please anybody with access to the server can PM this file to me???

Many thanks
