Corrupted file on Firmware. I can't do anything!!!

[satoshi]

The file "topmenu_plugin.rco" is corrupted, So now when Menu appear, it crashes. I only can use UMD Game (Because when you put the UMD the menu doesn't appear), Even UMD Video doesn't play. So, anyone knows, How can I move some file on my PC ("topmenu_plugin.rco") to PSP Flash without use of Browser (PSP Menu) (So, I can't use USB Mode and no Homebrews) ?

I thought If I buy a PSP Game that need to use 2.0, if I can Upgrade using a UMD to fix that error file...

is this about isos?

No, it's my Firmware (1.5) that crashes after appear "Sony Computer Entertainment", because that file is corrupted. how can I Fix that?

Try upgrading to 2.0 then downgrade back to 1.5. Why would your firmware be corrupted anyway?

That's the problem, How can I Upgrade if the main menu doesn't appear. I can't select "USB Mode" or select upgrade via Wifi, so... To Upgrade via UMD, some friends of mine (on the internet) said that you have to select "Upgrade" on Main Menu. So, there's no way that I can upgrade... or have another way to upgrade?

[Kaiser]

Hmmm... Yes you do have to select upgarde from the main menu. You might have to send that PSP to Sony or return it from where you got it for an exchange. Seems there is no other way of solving your problem.
