Black Box FTP & OpenPS3ftp are not fully functional. OpenPS3FTP is Open Source so hopefully someone will get a fully functional ftp app written for 4.21

That contain lv0-and encapsulated loaders cex 4.30 with inside appldr.elf + isoldr.elf + lv0-430.elf + lv2ldr.elf

I take the kakaroto 4.21 LV2 Patcher and click on " Open lv2.elf " and select the lv2ldr.elf.

I can see one thing different, the size of the lv2ldr.elf is 98 ko before i patch with kakaroto script and after 425 ko !

So what happen ?? Please take a look if you have more knowledge than me and sorry for my bad english.
