PS3 USB Custom Firmware Loader v0.3 Released by JaicraB!

Well there's the problem. you need to copy the CONTENTS of dev_flash to your USB drive, not the folder.

Your USB should look like this (where X: is your usb drive):-
X:\bdplayer\
x:\data\
X:\ps1emu\
X:\ps2emu\
X:\pspemu\
X:\sys\
X:\vsh\

(NOT X:\dev_flash\bdplayer .... etc)

man people - just try fat32 external drives. i had the same issue as everybody it was simply the usb and the fact my dev flash wasnt copied with winscp

ALSO its not

usb->dev_flash->etc

its just straight to the usb so all the folders are on the root.

well i went out and got a SanDisk Cruzer 1gb USB Key (formated in FAT), i downloaded WinSCP FTP and copied fresh dev_flash, dev_flash2, and dev_flash3 to the cruzer. still freezes on black screen. tried with and without JB (running latest Hermes PSGroove hex) plugged in on Firm Loader run, same result. So i have no more ideas.. maybe my At90usb1286/USB Firm Loader/PS3 doesnt like me?

Just thought i'd post to say that this worked great 1st time for me... My installation route (not a real guide like i used to do, but thought it might help some people)...

My Minimus AVR Usb (AT90USB162 chipset) arrived this morning.

1. I installed FLIP 3.4.2 + downloaded the x64 drivers

2. I flashed "psgroove_1.1_Teensy_1.0.hex" from the "PSGroove_1.1_All_Patched.zip" (Link see Evilsperms all pack) - includes peek&poke! (which is REQUIRED for Jaicrabs loader to work!)

3. I checked JB worked - it did, so installed CJPC's FTP server & Jaicrab's 0.3 firmware loader

4. I started up FTP server on the PS3 and hit START (seems some people miss this bit!)

5. I started up Filezilla and setup a new connection to my ps3's ip address, set the transfer mode to Active and only 1 connection (as per instructions)

6. Connected to PS3, downloaded all of (dev_flash, dev_flash2 & dev_flash3)

7. Plugged my VERY cheap usb drive into PC and put the CONTENTS of dev_flash on the root of the drive (as per instructions)

8. Plugged USB back into PS3, ran Jaicrab's loader and hey presto USB drive light flashing boot back to XMB (FYI no USB listed anymore)

9. Move around XMB and notice that occasionally the USB will flash when it has to re-cache icons.

Seems to work really well - will be customising the usb firmware a bit later, just thought i'd post this along with a big THANK-YOU to CJPC and Jaicrab

I should point out that this is the first JB device i've had, first time i've tried flashing it, first time i've used it etc. Amazing what reading a few forum posts and the instructions can do for you eh!

PSPSwampy.
Been feeling left out, glad Minimus was in stock when nothing else was!

In regards to the update file, you have also modified the files that don't seem to do much yes? IE. version.txt
