ok, i forgot to say, you have to attach fat32 formated USB key
Could you repeat commands ?

Added:
Is here an USB or HDD connected with two partitions?

Now those commands one by one:

Code: Select all

cat /dev/bml0/2 > /dtv/usb/sda1/dump_bml02

Code: Select all

cat /dev/bml0/4 > /dtv/usb/sda1/dump_bml04

Code: Select all

cat /dev/bml0/5 > /dtv/usb/sda1/dump_bml05

Archive it and give me to look at (attach here or on any source eg rapidshare...).

Added:
So i checked your dumps. bml2 and bml4 are completely empty and kernel - bml5 one byte is changed -all what post-FEB firmware does. So you are free to use instruction and files for LExxB650, because of identical file structure.
FFBv.0.3 now officially supports PSxxB650
Go to first post for further instructions.

You can prepare Firmware by extracting T-CHL7DEUC directory to USB
Or just douleclick on firmware exe file you downloaded and choose your USB...
You can copy telnet enabler too, no problem.

Oh, I thought I had to extract the firmware from usb tv in there and copy 3 files ...

FFB and telnet can not be installed at a time, a statement to me that such a file already in memory installed ...

[juzis]

what are you doing now? Are you trying to make firmware usb and downgrade, or you just inspecting how many games you able to copy to tv memory at once? If you need telnet enabler, you can delete ffb, download telnet enabler as trojan and copy it to memory.

But I have already successfully made the rollback, thanks for your advice!

Re: [How-To] ForceFirmwareBack (FFB) => ad) Service Menue => rs232

@ juzis28

Please can you help me?

You wrote on the first page „MAKE BEFORE START FFB“:

Enter Service Menu ...
Change setting (Control -> Sub Option -> rs232 -> debug<-UART-Logic)

But i only have the option:
=> RS-232 Jack => not „rs232“ and there are options:
=>„UART“ or(!)
=> „logic“
So there is no chance to select "debug" (or "UART-Logic").

So, what should i select? „UART“ or(!) „logic“?

I have LE40B650T2, T-CHL7DEUC, firmware 3000 but i need firmware 2005 for PVR-Function.

Thanks,
Bilbo995

[juzis]

it is my foul, should be rs232-jack, you have to set it to:
=>debug

Strange... why don`t you get to "debug"...
did you try to navigate backwards with left/right buttons?

[bilbo995]

Thank you!
I think I'm a dummy: i always used the right curser and doesn't found "debug". Now i take the curser to the left => and voila: her it is "debug"
