I have today tried to upgrade my F900 to 2.007 using the firmware on the Pioneer UK website. It seemed to upload fine, but after reboot I am getting a system start up in progress message that seems to hang.

I have tried to reset and upload the software again but all to no avail and I am just getting the same message over and over with no functionality available.

I have not used any hacks etc previously only having done the previous upgrade since it was installed.

Can anyone offer any advice to help me?

when the update sems to hang does part of the screen go RED? If so look at the screen and copy the file patch and file name displayed. The is an issue with that file. try copying it to the SD card again. If that fails download the update again and copy the file across.

It seemed to run the update OK and said it was complete and going to reboot. It was when it was rebooted that the problem started. If I put the SD card in now it just seems to ignore it and go to start up and then freezes.

Look at step 4,5, and 6.
