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 help

Bastien
