I have to flash my Strong 4450 because it dont want to boot up!
I had flashed some receivers before so I have a little knowledge...

Sometimes it just do nothing...

and sometimes it shows "bt2.0" and something before, but its just to quick to read it!!
If I push "channel -" and "volume -" (both two bottums in the middle!)
it shows dl |, the stripe is moving!!

So I think, I need to flash it to get it work or does it have another big problem?

Please help me!!!
