i designed many ota units, and made mod for it. afterthat i have 3 or 4 years do not touch ta again. and now, i see tas. and i think it is a good form. but now i want to transform my own ota unit to tas unit, how can?

I'm no expert but skip to step 6 Here

Effectively if you have the 3dos, tdfs, and cobs it's just a matter of putting them in the right folders... you might want to start by opening XTA with 7zip (sdz and sd7 are just zip files) and poking around...

To clarify, sdz is a zip and sd7 is a 7z.

and it's not tas anymore, it's srts

Old habits die hard.
