The steps outlined below allow the flashing of an image 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.

Device files used
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 Specific
- EXE_DEVICE=/dev/stl0/8
- APPDATA_DEVICE=/dev/stl0/9
T-CHU7DEUC Specific
- EXE_DEVICE=/dev/bml0/8
- APPDATA_DEVICE=/dev/bml0/9
Manual flashing steps
- (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( afterwards check out content and ensure it mounts without problems and looks ok from a content perspective. )
mount -t auto /dev/tbml8 /mtd_exe
- (9) 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 ;-)
Attention:This process does not validate the correctness and validity of the file being flashed. THIS IS YOUR RESPONSIBILITY!!!
