The LG BD-550 hack is back - Enable Youtube/Netcast/Picassa/AccuWeather on your player
Here is a description of the hack that enables Youtube/Netcast/Picassa/AccuWeather
I found this after a long search and wonder if anybody is willing to help out to make a noob tutorial with pictures that even would include some pictures and furthermore fexplains the RS232 connection to the Player!
I remember that the users "german" and "nicodocet" who created this hack posted that it probably would work for any firmware and very likely is update save, but that was one year ago! I once again would like to give german" and "nicodocet" tons of credit for this hack and it is sad that they seem to lost their interest in this project.
I haven't tried this hack yet but saw evidence that i worked Feedback i greatly appreciated. Repport your Firmware if you try it!
The hack:
It involved connecting to the player's linux console via an RS232<-->TTL converter and executing some commands using a terminal program. The original text:
======================Steps to Follow===========================================
1: Connect to the BD550 console, insert an empty USB storage pen and power on the device
2: Press any key as soon as you see output in the serial terminal
3: Change the boot arguments: (This is for my device with my firmware version, don't know about others). All in one line:
Quote:
set bootargs root=/dev/ram0 initrd=0xeb00000,0x167f8e console=ttyMT0 mem=256M mt85xx_reserve=239M,17M drvmem=32M,172M single mtdparts=mt85xx_nand:2M(boot_1),1M(part_info_1),1M (part_info_2),1M(mac_addr_1),1M(m2),1M(key_block_1 ),1M(key_block_2),2M(fe_bin_1),2M(fe_bin_2),1M(fe_ test_data),1M(fe_parameters),1M(fe_power_curve),2M (kernel_1),2M(k2),4M(initrd_1),42M(rootfs_normal_1 ),20M(rootfs_enc_1),2M(i2),17M(r2),6M(re2),1M(upgr ade_status),1M(fast_init_logo),1M(fast_init_param) ,1M(log_raw),14M(ubi0)
It is almost the default boot args, but with the "single" addition, and some shortening of numbers and unlikely important partitions, to be able to fit it in the 512 character limit
4: Boot the device:
Quote:
mt85xx_boot nand
You will land in a linux shell
5: Edit /etc/init.d/rcS, and remove the # from the line that ends with "telnetd &":
Quote:
sed -i -e '1,$s/^#\/usr\/sbin\/telnetd \&/\/usr\/sbin\/telnetd \&/' /etc/init.d/rcS
6: Resume the standard boot process
Quote:
/etc/init.d/rcS
You will see some serial output, but nos as much as a standard boot. When the output stops:
7: Press:
Quote:
Ctrl-Z
The startup script is suspended, and you land again in the shell.
8: send this command to make a copy of your config_file.txt on USB storage pen
Quote:
cp /mnt/ubi_boot/acfg/config_file.txt /mnt/sda1/
unplug USB storage pen and plug it to your PC
- make a backup copy of config_file.txt
- with an hex editor, open config_file.txt and search for these strings changing as follow the last hex value before the next IDX in the file:
Quote:
"IDX_PROTECTED_REGIONCODE" 0x00 (for region free)
"IDX_PROTECTED_BDREGIONCODE" 0x01 (for area A) 0x02 (for area B)
"IDX_OPTION_10" 0x05 (for AccuWeather/Picasa/Netcast)
"IDX_OPTION_11" 0x03 (for youtube)
- plug USB storage pen again to the BD550
- send this command to overwrite existing config_file.txt with the modded one
Quote:
cp /mnt/sda1/config_file.txt /mnt/ubi_boot/acfg/
9: Wait a few seconds and then unplug and replug the device
