[SOLVED] LN40B630 Help Bricked... in trouble with parents :(

[juusso]

what about dumps from LN40B630 /dev/stl0/6? Should i see if i can find one?

Another LN40B630 owner has to make dumps of /dev/bml0/5 and /dev/bml0/6 and share with us. If you know someone with exact same TV, yuo can ask him for help else someone maybe might help in this forum.
If you could boot kernel made from this dump, you would able to restore rootfs (its dump of /dev/bml0/6).

I suggested to do an emergency upgrade, but noting happens, no USB recognition by kernel (or here is another reason for that -tv won`t accept USB)
About Shell on serial console - i`m waiting for answer too, but Flipper doesn`t read posts carefully , its because his pregnant girlfriend i think...

Stop, wait!
At first, if you had an alternate firmware before flashing patched one? If yes, execute this command and reboot tv

Code: Select all

touch /mtd_rwarea/PartitionSwitch_0_0
/mtd_boot/MicomCtrl 143

After reboot if no success try in console:

Code: Select all

insmod /lib/modules/fsr.ko
insmod /lib/modules/rfs.ko
insmod /lib/modules/fsr_stl.ko

execute these commands one by one and write here output. If no errors you get, try attach usb and execute code

Code: Select all

df -h

I think it isn`t just exe.img and appdata.img problem, because you are not able to boot your tv`s rootfs via tftpboot (or maybe kernel you are booting is defect)

[juusso]

It seems that neither alternate nor basic firmware found. Or it couldn`t be mounted to rootfs because of it damage. Now i haven`t any idea except to search for dumps of kernel and rootfs.

Oh, i see your output of mount
you are missing firmware partitions:

Code: Select all

/dev/stl0/10 13.3M 13.3M 0 100% /mtd_exe
/dev/stl0/11 13.0M 13.0M 0 100% /mtd_appdata

or if with alternative firmware:

Code: Select all

/dev/stl0/8              13.3M     13.3M         0 100% /mtd_exe
/dev/stl0/9              12.7M     12.7M         0 100% /mtd_appdata

what is the output of

Code: Select all

cat /proc/partitions

Is your usb attached to tv where commands df -h and mount are shown?
To restore missing you you need USB at first...
try

Code: Select all

/lib/modules/rc.local

[juusso]

Didn`t you change model number in service menu?

added:
try insmod:

Code: Select all

insmod /lib/modules/usb-storage.ko
insmod /lib/modules/usb_fault.ko
insmod /lib/modules/usbcore.ko

or i do not know if the order for modules is right, try in another order to load these modules.
