Dumping and Flashing images by hand

The steps outlined below allow the flashing of a Firmware file directly into the flash of your TV, without using the offical upgrade process of the TV.
The example shown below is for flashing a modified exe.img on a UExxB70xx.
There is no need to flash app_data Image, if the actual exeDSP Version is unchanged and you are flashing your personal changes.

1. Prevent TV from rebooting when exeDSP is stopped
   /mtd_boot/MicomCtrl 23
2. Stop exeDSP binary
   killall -9 exeDSP
3. Unmount the respective directory
   umount /mtd_exe
4. Take a backup of the current image in the flash.
   bml.dump /dev/bml0/8 /mtd_swu/exe.img.orig
5. Move backup image to a safe space ( e.g. USB ) and remove file from /mtd_swu
   mv /mtd_swu/exe.img.orig /dtv/usb/sda1
   rm /mtd_swu/exe.img.orig
   
6. Copy Image to be flashed from your USB to /mtd_swu
   cp /dtv/usb/sda1/exe.img /mtd_swu
   ->this is the safest way, even though flashing directly from USB-Device may also be possible, which I have not tested
7. Perform the actual step of flashing the file.
   bml.resore /dev/bml0/8 /mtd_swu/exe.img
   -> Flashing progress will be shown 0% ... 100%. Don't interrupt this process!!
8. Mount the updated image
   mount -t auto /dev/tbml8 /mtd_exe
   -> check out content and ensure it mounts without problems and looks ok from a content perspective.
9. Try starting exeDSP
   /mtd_exe/rc.local
   ->If something went wrong and your exeDSP doesn't start up properly, then you can flash back your backup ".orig" image following steps 3-9.
   -> Don't worry, if you see your screen upside down. That is just due to a variable not been set ;-)

Find below the device files for different areas of the firmware for FW types listed ( this information is taken from the run.sh file and was not validated! )

• T-CHL5DSEUC, T-CHL5DEUC and T-CHU7DEUC
  • BOOTLOADER_DEVICE=/dev/bml0/2
  • FNW_DEVICE=/dev/bml0/4
  • KERNEL_DEVICE=/dev/bml0/5
  • RFS_DEVICE=/dev/bml0/6
  • BOOT_DEVICE=/dev/bml0/7
• T-CHL5DSEUC and T-CHL5DEUC
  • EXE_DEVICE=/dev/stl0/8
  • APPDATA_DEVICE=/dev/stl0/9
• T-CHU7DEUC
  • EXE_DEVICE=/dev/bml0/8
  • APPDATA_DEVICE=/dev/bml0/9

Attention:This process does not validate the correctness and validity of the file being flashed. THIS IS YOUR RESPONSIBILITY!!!
