No, you just try and upload the firmware again.

Firmware won't download with my app . My apple phone says-unable to read/ validate settings.Check your user/meth settings to ensure they are correct,
which is the firmware. How can I validate if I can't connect to the jb4 . Their is no disaster recovery for
it,so best case scenario is to send my clipboard to be reflash or buy just the jb4 box for $175.I was thinking buying a new JB4 box only?

Sounds like you have the bluetooh module- correct?

Try deleting & re-installing the app on your iphone.

Yes I have blue tooth module . Try app three times reinstall nothing. Disconnect battery nothing.
Put connect kit with 12V power nothing. What do you recomment?
1-Send chipboard for reflash
2-Buy new jb4 box for $175.
I can't communicate , because it left car without firmware.

have you tried removing the jb4 / starting the car?

i'd also inspect the jb4 in general- sounds like maybe it lost power or a connector may be lose- which is why the bluetooth can't find i.t
