hello,
sorry for my bad english but I'm a little French.
I wanted to update F500BT of my dad and there is a big problem.
Here's how I did:
it was a version 1.00.1000
I did not make a backup copy.
I put the updated official pioneer in 2.xx with a SD card
Then 4.xx
reboot after the GPS, I get a message that says:
"The boot is in progress. ... Please wait"
and I can do anything I expected and after several hours, I am told it is locked.
I searched the forum but I have not found an answer corresponding.
can you, if you like it, help me. how do I unlock?
thank you for your
