Dump of UN46B8500 Need help/info

Post by kpkev » Sat Jun 16, 2012 5:49 am

I have a UN46B8500 and have looked around and cannot find any info on original firmware. I would like to know if my current firmware is modifiable or not, and if it is how do i go about using a dump to create a modified firmware that i can flash.

UN46B8500
T-CHE9AUSC-1008.1
current version 2009/11/02_001008

If you need anymore info let me know.
Kevin

i think i must translate: arris says, your firmware can be modified by hand by yourself. If your firmware is not supported by SamyGO patcher, it is not hard to do firmware modifications on linux...

after i unsquash dev block 07 (its 2mb) i see the .ko files. (Is this the exe.image?)I just want to be able to use the sammy go remote. What are the minimal steps to get the firmware to allow me to use things like sammy go extensions. Also if i edit the 2mb file is that all i need to modify, do i need to edit the versi0n info and crc info? In my dump i also have a 60mb file and a 45mb file. d o i need to do anything to them.

I really dont want to brick my tv but want the extra functions.
Scince i provided a dump of my tv if someone with access to a linux system would be willing to do the editing i would greatly appreciate it. If not is there a step by step for windows.

thanks for the fast responses
Kevin

no, its the /mtd_boot partition.

you don't need to change anything on the firmware, just put the extensions-pack to usb and start it from "Content Library"
Also if i edit the 2mb file is that all i need to modify, do i need to edit the versi0n info and crc info? In my dump i also have a 60mb file and a 45mb file. d o i need to do anything to them.
we have a wiki page how to play around with firmware images on b-series
I really dont want to brick my tv but want the extra functions.
then not play around with the firmware...
...

If you need only Extensions, you can run it as game from ContentLibrary, as you ran DumpMaker too. For this you do not needed to modify the firmware at all.
If you need autostart for Extensions, then yes, you have to modify exe.img (or dump of), according wiki article.
(;/mtd_rwarea/SamyGO.sh& on rc.local)

Update:
But if i have time i will look in to the patcher and maybe here is chance to add support of your firmware.
Just looked in to your /mtd_exe/rc.local:

Code: Select all

#!/bin/sh

export MAPLE_DEFAULT_PATH=/mtd_cmmlib/InfoLink/lib
export MAPLE_MANAGER_WIDGET_PATH=/mtd_down/widgets/manager
export MAPLE_NORMAL_WIDGET_PATH=/mtd_down/widgets/normal
export MAPLE_WIDGET_DATA_PATH=/mtd_down
export MAPLE_WIDGET_INCLUDE_PATH=/mtd_down/widgets/inc
export MAPLE_PLUGIN_DATA_PATH=/mtd_cmmlib/InfoLink/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mtd_cmmlib/YWidget_LIB
export KF_SLEEP_READ=-2
echo 30000 > /mtd_rwarea/DelayValue.txt
touch /mtd_rwarea/DoPrintYahoo.txt
export KF_NO_INTERACTIVE=1
export KF_LOG=/dev/null #Remove engine logging.
cd /mtd_exe
./exeDSP
All correct, could be supported ;)

Update2:
I modified the dumps of bml0/8 (1008) and bml0/10 (1010) for you. You can flash it to TV and now your TV will execute /mtd_rwarea/SamyGO.sh if you create it. Download.

Code: Select all

#!/bin/sh

export MAPLE_DEFAULT_PATH=/mtd_cmmlib/InfoLink/lib
export MAPLE_MANAGER_WIDGET_PATH=/mtd_down/widgets/manager
export MAPLE_NORMAL_WIDGET_PATH=/mtd_down/widgets/normal
export MAPLE_WIDGET_DATA_PATH=/mtd_down
export MAPLE_WIDGET_INCLUDE_PATH=/mtd_down/widgets/inc
export MAPLE_PLUGIN_DATA_PATH=/mtd_cmmlib/InfoLink/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mtd_cmmlib/YWidget_LIB
export KF_SLEEP_READ=-2
echo 30000 > /mtd_rwarea/DelayValue.txt
touch /mtd_rwarea/DoPrintYahoo.txt
export KF_NO_INTERACTIVE=1
export KF_LOG=/dev/null ;/mtd_rwarea/SamyGO.sh&
cd /mtd_exe
./exeDSP
1. Before to start it is necessary to change service menu settings (Control-sub option):
Setup rs232 to debug
Watchdog off
2. attach usb with bml10_mod.dmp, start telnet enabler and conect to tv.

Code: Select all

bml.restore /dev/bml0/10 /dtv/usb/sda/bml10_mod.dmp
sync
3. If no errors come (100% success):

Code: Select all

touch /mtd_rwarea/PartitionSwitch_1_0
rm /mtd_rwarea/PartitionSwitch_0_0
sync
/mtd_boot/MicomCtrl 143
TV should boot to patched firmware (which is your alternative firmware T-CHE9AUSC-1010, but now - modified.)

4. Next you have to learn how to make proper /mtd_rwarea/SamyGO.sh and add all stuff you need to execute at autostart to it.

If you acceddentally get bricked TV, you need to build exlink cable. But i dont think this is needed. Should be ok.

I analyzed your dump of bml0/2 (u-boot), bml0/4 (fnw) and kernel (bml0/5) and apologize: your console is restricted and here is no u-boot access over exlink.
To be prepared, you have to restore those with required ones to have chance in future to repair tv if bricks.
