Hello,

My F900 was running the V3 OS fine for months. It has the hardware hand break mod.

Few days ago, I updated the phone book via Bluetooth, and did not see any errors. (I did get a call during this update)

This phonebook update may not be related but since then the unit does not boot. It keeps cycling the boot process with Pioneer splash screen.

A few time it did boot (while I was driving) but GPS was not working at all (i.e no signal) and once the illumination lights were flashing, no matter what mode/color I selected.

But the phone book data was there, however I don’t recall if it was showing the new or old data.

I tried booting with testmode, and I don’t think it even attempts to read from the SD card, cus the reboot is way too fast.

I searched around the forum, and only suggestions was to boot with testmode and remove the user files, which I cant do since it doesn’t boot in testmode.

On a Z forum, I read about similar issue that was related to flakey wiring. I will check that tonight, but I don’t think that my wiring is bad. I have done a good job with soldering and shrink wraps.

Any suggestions ?

Thanks

Mine is doing the same thing running 2.0006 firmware. Pioneer has confirmed at three levels of their support that "this is a known glitch". They gave me two options. Send it in for repair or replace the unit.

I fixed the problem.

I couldn't boot in test mode, and pioneer told me to send it to service. And futureshop extended warranty would leave me without a unit for 4-5 weeks. (the only reason I got the PSP was due to the big discount to match crutchfield prices)

Took the unit out, checked the wiring, .. and it was all good. <- That's why I did it myself. So I know the wiring is done well and will last.

The unit was still responsive to the bootrom menu. (holding the reset, eject, Menu and Map).

I ran the memory tests and all passed. The GPS test didn't do any thing.

Then I reloaded the windows CE (no format). Then tried booting with testmode, and still was not able to boot.

Then I retried to reload windows CE with format, and now I was able to boot with test mode. The rest was just 30 min to reload the image. The unit is now back up and running.

Cheers

I have done a format install of 3.0 following the published howto. Worked like a chammp. Now to update to 3.01 and reload the hacks.
