who has launched firm 2.00 on their u.s 1.5?

yea so anyone manged to successfully launch firm 2.00 with wabs firmware launcher on their U.S. 1.50 psp? Because when i do it i get a blue screen thats says to press 0 to restore settings and when i do it just goes to 1.5 screen with 1.5 features.
If u have could u state ur exact steps on how u did it.

I haven't but I'd like to...

do you know how to do it? i don't understand. I'll do it if you give me some instruction

ok well u need these things to do it:
1.mphFL (firmware launcher)
2.an eboot of the firmware u want to launch
3.pbp unpacker, to extract the data.psar (contains the firmware files) from the eboot.pbp
4.psar dumper (dump the contents of the psar into folders in the root of ur psp)

ive done everthing to do it but when i launch the mphfl and start to emaulate 2.00 i get a blue screen sayn to press0 to restore, i didnt get that however when i launch firm 1.52

ok heres something if i load up 2.5 on my psp and put gta in will it work?

see thats what i wanna know, i dont own gta so. i have a zip file with firm 2.5 rdy to launch of anyone wants to take a whack at it and play gta while its loaded ill send it to u, it includes a readme.

By now i have manged to load firm 2.5 on my 1.5
pluses:
web browser (which can work but u have to do something which i havent done yet)
theme settings
GTA MAY BE PLAYABLE
video formats

minuses:
crashes randomly
no photo viewing
no music listening
no save data viewing on 2.00

if they fix those us 1.5ers will be set for awhile

I have 1 and 2, but I also have a mac, so I dont think I can do 3 or 4

well the pbp unpacker is an .exe and the psardumper runs on a psp not a pc or mac

iv'e done everything it said but all i get is like 8 lines that say error with like 8 .prx files can any 1 help?

i have the 2.5 ziped and rdy to launch, u want it?

by now, i have managed to web browse on my 2.5 but it crashes randomly, also mph has released another firmware launcher that supports umd launching, but i still dont if the umd accesses ur 1.5 files or the current firmware thats loaded so GTA might be playable on 1.5 but i still dont know so i have emailed MPH about this.

now have been able to successfuly browse pspupdates.com without the browser freezing, if it freezes, the psp simply turns off and when it comes back on goes back to 1.5
downside to browser- u cant save anything from it
[update]
now have photo viewing in 2.x
