ok, i forgot to say, you have to attach fat32 formated USB key :lol:
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 ...

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. :!:

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?
