Deed done. Thanks for the tutorial.
Background:
I have a slim which came with 3.90, a SanDisk 2GB ms, and a Datel service battery.
I followed the instructions and selected option 4 from the installer (3.71 and recovery mode).
When it came to installing the firmware I had the expected blank screen of doom. I pressed [] and the memory stick started flashing - this was dumping the NAND. It shut off so I reinserted the battery.
Again, a blank screen so I pressed X to install the firmware.
Once all was installed (takes a few minutes), I removed the battery and ms, rebooted, and my PSP had the correct custom firmware installed.
So, even with the blank screen, as long as you know the correct buttons, the tutorial works fine - so don't panic.
