Hallo007 has just updated his Flash Agent homebrew flashing application to version F1 today to support - you've guessed it, multiple firmwares. Flash Agent revision E2 was released a few days ago which supported Dark_Alex's 3.10OE but Hallo007 has realised that a lot of people have stayed on 3.03OE, perhaps not noticing the POPS changes in 3.10 and therefore this version supports both 3.03OE and 3.10OE ONLY. No previous custom firmwares are supported, so do not attempt to use it with any firmware other than 3.03OE or 3.10OE. Here's the changelog:

* Now works on 3.03OE and 3.10OE firmwares
* Topmenu_plugin enabled for 3.03, disabled for 3.10OE
* New ICON0.PNG (made by silvenius)
* Give your own site as online instruction manual
* Logo while start up(by Moose_Island)
* Exit on non supported firmwares
* Added 'accept agreements' screens
* Rco file menu

Remember that flashing your PSP can be dangerous and could cause a brick so be careful when you do anything! This application can be used to free up space on your flash chip, change your gameboot, and of course you can even restore the flash to default settings.
