I can`t backup TV partitions

[juusso]

wrong command line. Right one is:

Code: Select all

bml.dump /dev/bml0/10 /dtv/usb/sda1/tbml10_dump

and so on...
you have to write /dev/bml0/x where x is partition number.
you can`t dump stl partitions with bml tool, you need to use cat.

p.s. why don`t you read manuals. You can see on wiki:

bml.dump /dev/bml0/1 /dtv/usb/sda1/dump/bml0_1_dump
bml.dump /dev/bml0/2 /dtv/usb/sda1/dump/bml0_2_dump
bml.dump /dev/bml0/3 /dtv/usb/sda1/dump/bml0_3_dump
bml.dump /dev/bml0/4 /dtv/usb/sda1/dump/bml0_4_dump
bml.dump /dev/bml0/5 /dtv/usb/sda1/dump/bml0_5_dump
bml.dump /dev/bml0/6 /dtv/usb/sda1/dump/bml0_6_dump
bml.dump /dev/bml0/7 /dtv/usb/sda1/dump/bml0_7_dump
bml.dump /dev/bml0/8 /dtv/usb/sda1/dump/bml0_8_dump
bml.dump /dev/bml0/9 /dtv/usb/sda1/dump/bml0_9_dump
bml.dump /dev/bml0/10 /dtv/usb/sda1/dump/bml0_10_dump
bml.dump /dev/bml0/11 /dtv/usb/sda1/dump/bml0_11_dump

why do you write incorrect then?

[juusso]

bml0/8 and bml 0/9 are first firmware partitions
bml0/10 and bml0/11 are second firmware partitions

Here are two firmwares on TV: current and alternative.
with command df -h you see only curently active/mounted partitions. Alternative firmware is invisible.

enter

Code: Select all

cat /proc/partitions

and you`ll see how many partitions here are on tv...
0/2 ...0/11... 0/17 are partitions of NAND (1) on 1Gb memory models.
1/1...1/2...1/3 are partitions of NAND(2) - on 2 Gb memory models.

whole partition bml0/c and bml1/c - you get 1 Gb file. But i do not recommend flash it back, you could brick TV...(i guess)

p.s. I tested your map widget, do you have another interesting stuff to try?

[juusso]

you dump partitions, not only firmware partitions (u-boot, kernel, rootfs and other) with bml.dump.
ContentLibrary is on /mtd_tlib , it is mounted as /dev/stl0/13
So you can dump it as:

Code: Select all

cat /dev/stl0/13 > /dtv/usb/sda1/dump_stl_13

But restore is others.
what is your TV model?

juuso:
My TV is a Samsung LE32B651T3W (yera 2009 model) with telnet access hacked firmware T-CHL7DEUC 2005
I would like to learn more things about my TV file system, can you made me any recomendation ?
Lately my TV response is more slow and it suffers a total block from time to time.
I am thinking about to made a RESTORE FACTORY DEFAULT or downgrade to previous firmware T-CHL7DEUC 2005 (original, non-hacked)
That?s the reason of the backup and dump I made.
I will tell yoy If I success. Thanks a lot.
p.s. I fell happy if you like my map widget. Widget Programming is a lot easier than all this linux stuff.

------

Partitions where firmware is stored are bml0/8 bml0/9 and bml0/10 bml0/11 (check your df -h for currently active firmware)
You can update your firmware normal way over TV menu - you have unrestricted firmware - why you need flash it at hand?

If you want lern deeper, you have to order exlink cable first!

you can use DumpMaker for making dumps
