Here are my notes on flash.bin recovery
I do not know if they are the same for the TT unit.
flash.bin recovery is done like this.
Place a copy of the unpacked software (the .bin file) on a USB stick and rename it "flash.bin"
With the USB in the unit, power on while repeat pressing "Menu" on the remote.
The unit should reload the software.
Also other users say that you must use a USB stick, not a card holder etc and that stick must be 32Gb or under.
Use the rear USB port on units that have two ports.
I have had units that will not recover.
Try using the same software as was in the unit when it crashed, not the new update software.
You must use the correct software, ie that for the V7HD for the V7HD etc, not software for any other freesat units.
Try even older software as the file for flash.bin.
Look at the LED in the USB stick. When the TV shows the message "USB Upgrade, do not turn off" you should see the LED on the USB flash as the file is loaded.
The USB LED should also flash a few times as the unit first powers on and looks at it.
Also users have said to use the rear USB port for this on V8 units.
New information: Users are reporting that naming the file "Flash.bin" with a capital has worked where "flash.bin" has not. This is with the Nova units mostly.

I found that a USB stick with a lot (more than 30+) .bin files on it, my UHD unit would not show the new software file in the menus.
This suggests that having too many .bin files on the USB stick can also be a problem.
I moved most of the file into a folder and it then showed the file.
Keep only one or two files in the main directory.
