PROBLEM Upgrade 3.01 by Retell TO official ver. 4.0

Posted Aug 04, 2011 · 14:07 UTC#1

Hi falks,

my F900BT was messed up a year ago due to irregular booting, and the only reasonable way to restore was to fully install "FX3.1 Complete Firmware Image by Retell" (post. on Sun May 09, 2010 8:00 am). Now, Pioneer released ver. 4 that I downloaded from the official site (http://www.pioneer.eu/eur/support/software/AVIC-F900BT/index.html), but the system does not recognise the SD card as an update card (starts normally, like the card has nothing in it).

Q1: Is it because of the hacked 3.x update, or there's something else wrong?

Q2: Is there a way to force the system to read the card as an update card?

Thank a lot to AVIC411 and all the guys here, you're helping a lot us rookies!

4.001 is an update to 4.000, you need to get that first which comes on sd cards from Pioneer.
