E3 Flasher Limited Questions (about Using Other Cfw) Options

[qUaK3R]

Hey everyone,

So, i'm about to receive a e3 flasher limited at home, but, after weeks of searching the web, and trying to translate english, french, german, and romanien to my language, i still have some doubts, beacause of the boggus information i sometimes find.

i have a ps3 slim CECH-2000 something (yes, it's compatible), and it's now on 3.70 something firmware. The thing i wanted to do is getting it to run on dual boot, between 4.11 OFW and 3.55 CFW, but NOT the cfw E3 provides, since it's outdated, and their multiMAN is also outdated. The CFW i wanted to use was either kmeaw's, rebug's, or rogeros, and with that, using the latest multiMAN. Is it possible to do the process directly and have what i wanted, or do i have to take a risk to get the CFW of my choice, or is it simply not possible, and i have to get stuck with E3 material? Does someone recomends something else?

I think i have all the files i need, OFW 4.11, E3 Files, PS3Jig for PSP and up to date multiMAN. The use i want to give to my ps3, is to run some "Backups" (not counting on recent ones, but counting with some that i can patch, even if i don't know how yet), running some emulators, and sometimes, swaping to OFW to use PSN, and some original games i got (yes, i've got some xD).

Thanks in advance
