After firmware update my car radio died with black screen. No display, only buttons light up after I connect my phone via bluetooth and make a call... I have LTTF133.img, LTTMcu.bin from manufacturer but after uploading on flash drive and putting it in the radio no effect. Anyone who has 16mb...

I have the same stereo, and it has some very annoying bugs. It keeps turning on by itself and going to radio mode. Any luck with the firmware update?

Mine does the exact same thing. It will work, then shut off and go to the radio. I am trying a better antenna to see if that makes a difference.

After firmware update my car radio died with black screen.

No display, only buttons light up after I connect my phone via bluetooth and make a call...

I have LTTF133.img, LTTMcu.bin from manufacturer but after uploading on flash drive and putting it in the radio no effect.

Anyone who has 16mb bin dump from eeprom of this radio or any idea how to revive it?
