Yes, CFW seems that much closer now. It seems that Jaicrab and ps3mrenigma have teamed up and produced an app that allows writing to dev_flash.
JaiCraB and ps3mrenigma have released an app that gets us one step closer to custom firmware. Their app, entitled Mount Alejandro, enables writing to the dev_flash, by mirroring dev_flash to dev_alejandro and making dev_alejandro the active one. As everyone should know by now, dev_flash are where your console's firmware files are stored after installation. Please use caution when using this app since it deals with your PS3's flash.
FLASH WRITER ENABLER:
This application allows the mounted one of the /dev_Alejandro unit. This unit is a mirror of the /dev_flash unit, being this active one also.
The /dev_flash unit lacks permissions of writing, useful to read like towards formerly, nevertheless the new one, IF it has writing permissions.
It is for this reason, that we do not become people in charge of the evil use that can be given this application, to the used method, etc. As end users YOU ARE RESPONSIBLE FOR the USE THAT YOU DO OF THIS PROGRAM IN YOUR MACHINES!
To have it in account before wanting to manipulate firmware, archives XML, etc.

P.S Because the name of Alexander? Who knows, equal has something to see with some of us…: P
And please heed the warnings in the above post. This app DOES deal with your ps3's flash so you can potentially brick your system if you dont know what you're doing!
