[App] ForceFirmware Back (FFB)

[elui]

Hi

After deleting horse from TV and repeating again, It worked.
I don't really know what I did differently except that this time I extracted exe file to HD first and the copied files to USB.

I have one more question:

It says

"13. It is recommended to use normal firmware upgrade procedure (from TV menu-help-software upgrade) to delete post-FEB firmware from TV forever."

When I try to upgrade to 3000.G it says that I am already in the same firmware version so it refuses to upgrade. What can I do? Should I leave it as it is?
Can I use now SamyGo Firmware Patcher Script in order to patch FW to automount SAMBA?

Thanks for all

Nothing has bee changed at your side, just another version of FFB was uploaded to server by me

Yes, you can skip 13 and use firmware patcher. Install patched firmware normal way, over menu-help-software upgrade...

Hi,

first of all compliments, I hacked several things but never a TV!!
I have got a LE52B750U LCD TV with 2010/04/21_003001 firmware.

I want to use the android remot control and tried to downgrade to T-CHU7DEUC-3000.G (the first link on you guide [even if there are 2 links with the same name "T-CHU7DEUC-3000.G ").

FFB starts and goes in Error: the Firmware is wrong !

First of all I am not shure about the CI or CI+ issue (what is the right one for my tv?).

attached my configuration

p.s. during the step "0" (change settings of wiselink write, watchdog, etc) I made a mistake and did a factory reset.

thank2 a lot!!

hi, please upload log files you`ve got on usb. thanks.

[pippopippo]

attached the loog files (in the root of my usb key).

thanks

[juzis]

if your firmware is T-CHL7DEUC, then why do you use T-CHU7DEUC???

Code: Select all

[00:01:57] Found: T-CHU7DEUC firmware on USB.

You have to use:
T-CHL7DEUC-2004.1
T-CHL7DEUC-2005.0

for downgrade.

[pippopippo]

right!

I did not focused on that!

thanks a lot. What do You suggest, 2004.1 or 2005.0 ?Is there any difference in playnk MKV? I have an HD connected via USB used to read MKV films (mostly 720P).
thanks again

[juzis]

Feel free to use any of them. Or you can use moded firmware for ADFIX and GMT time zone patch, based on 2005.0. No difference in supporting movie formats.

[pippopippo]

ok, thanks again, 2005.0 is running now..

I will install remote contoll app....and what about DTS...or other useful games?

Hi, I followed all the steps, I made 3 attempts but doesn't work...(I could only get back to the alternative firmware from 3001.1 to 3000)
My model is LE32B6502W firmware T-CHL7DEUC and these are the log file of the last attempt:

Code: Select all

The program loads the firmware and after a few seconds the TV will restart but still with firmware 3001.1. I do not understand where I'm wrong...
