Eurovox 7000 HD transponder/channel issue and channel file

I am very familiar with Eurovoxes.

I have recently purchased a 7000 HD living in the t/w area in london.

i have flashed the march firmware update.

The first time I set up the box I did the deep scan for the first time and it worked perfectly receiving every single channel.

Being stupid I wanted to do it again just to change the auto dort function and since then I have only been able to pick up 180 channels, the problem is that a few of the good channels are not accessible like sk* 1 2 3 , BBC 1. etc...

I have tried all sorts of options such as deleting the channels / factory reset, all types and variations of scans, changing the steps, and most other options.

When I do a transponder scan I do receive most of the transponders, although I believe I may not have the wall, I believe what my main problem is that I need to input the frequencies manually that I missing something channels?

Would anyone know if there's something glaring that my missing walker from across this problem?

If i scan in the early hours aand early morning would i have more of chance of getting channels?

Does anyone have the channel file/list for the London area?

Does anyone have a frequency/transponder list for the area?

Any help would be much appreciated!
