thanks xavier... one more question - is the screen easily swappable?
(slightly ashamed to say that i bought my preenfm2 ready-built)

preenfm2 and preenfm3 / Will this screen model fit the new metal case?

Hi Xavier,
Just wanted to check if this model would fit the new metal enclosure or not?

I'm on 2013 i7 iMac running 10.9.1

One thing though, pressing eng still = no access to USB on the mac

It was the USB stick! Received the Sandisk Cruzer yesterday & upgraded to 1B4 this morning with no troubles at all... Thanks for the troubleshoot help :)

ok, just ordered one, will report back when it arrives :)

Cool, no worries. Let me know when you need me to test again

By the way, is there a recommended USB stick I should try? Might be a quicker solution. I just want to get your new FW, the new features look great :)

1. emptied cache, dloaded again, no joy
2. tried the following:0.9po, 0.9oo, 0.9no, 0.9io

only version "i" will load

So i switched back to 1.02 BL, and on my USB are 2 FW 0.9io & 1B3o.

If I USB install 1B3 & reboot, I get blue screen.
If I install 0.9i, all good.

Yep... with 1.02 BL, upgrade by USB works fine.

To make sure i'm not misunderstanding, you would like me to add FW 1B3 manually to the USB, reinsert USB, then upgrade by powering up & pressing Op

OK sorry for the confusion

after i managed to get 1.02/09 working, I upgraded boot loader to 1.10 via DFU.

This worked, & for the 1st time I had functional preen with 1.10 & FW 09.

But that's where progress stopped, I still cannot see USB on PC when I press Eng.
And I can't upgrade FW to 1B3 either by USB (just hangs with "USB UPGRADE" message) or Sysex (receives sysex, asks me to reboot, blank screen again)

OK, so i re-flash bootloader 1.10, and now it keeps firmware 0.9... but when I try to upgrade firmware via USB to 1B3o, no joy. Same with sysex upgrade.


ok I've formatted the USB, but the same happens. For what it's worth, the USB behaves normally on both my mac and PC. The good news is that I've now managed to get boot loader 1.02 back on and have also got firmware 0.9 back on... So I have a working preenFM again (woohoo).

So, maybe I can start again using PC for DFU to get 1.10 back on? Or can I skip DFU entirely?

1. & 2. Correct

Sub menu, if I press the following buttons, screen reads as follows

Eng: Bootloade v1.10 (USB drive not visible on PC)
OP1: USB Upgrade (but nothing further happens)
OP2: Sysex Upgrade, Erase firmware (it formats if I press erase, seems to accept the sysex message, but on reboot - no change, still blank screen)

I run the cmds for install bootloader then overclocked firmware, but on removing jumper, reconnecting CERB and powering it back up, i still get the blank screen. I also still get the bootloader 1.10 prompt if i power up & press Op

so even on pc, it seems there's issue with getting the bootloader onto the preen, please see the line "aborting previous incomplete transfer"

or maybe that's normal, but the symptoms on the preen are still the same as before...
