Got the same issue with the impossibility yo use dev_blind and anything else involved with write permission on flash (tried all pkg available) probably due to some mess.

I reinstalled Kmeaw on Kmeaw in recovery mode after no bootup of PS3 nothing lost of course but this was one of the issues. Today after installation of Multiman 1.16.05 or some other miracle I am not able to explain everything went back fine, dev_blind mounted again and push_cert (for example) working...

Thanks to the PS3 saint...

Im actually able to write to dev_bling using the multiman FTP, thanks though. whomps, you have been moving links to games and stuff into it? Or the links to the utilities like Game Data and stuff?

Hi seve. You need to use dev_blind app. mount your dev_blind and then open awesome filemanager to replace with: Dev_blind\vsh\resource\explorer\xmb.

you can't see the de_blind drive using the ftp server dunno why.

Yeah it's a pain but never a bad thing.

What I have done so far is make psn area another game area. I am going to try to figure out how to make the package files when installed with installer under there to only show up there and not in game area as well.

I may not be able to but think it would be nice.

Ahhh makes sense! Taking some of my own advice and reading the instructions for once helps. Thanks.

It may be something to do with the firmware you are using. Some things don't work the same on 3.41 as 3.55. Maybe try the new hermes bum that was released for 3.41. I think I remember it said it has ftp build in it now. Would be easy enough to try it and see how it goes.

You must open dev_blind folder not dev_flash when you want to copy back.

I used dev_blind. You can add to areas also. This attached file is my psn area now with install pkg under it.
