rains works as well as the other mmses.if your on vista.this could be the cause of your problem.use windows xp and also make sure your signed in on admin account

im not signed in an admin account. why would that make a dif?

[ƒR()§†H@X]

because hardly anything works on a guest acct on a computer,because thats basically telling the computer to limit you from doing much of anything on it

im not a guest im on a limited account. i can still use mms like a reg program but not sure how on a admin?

I just downgraded my friend's phat 4.05 ofw to 4.01m33-2 yesterday. I used the Universal Unbricker (Despertar del Cementerio) and it worked like a charm.

limited account/guest is the same thing.it makes you not have access to certain things such as formatting the memstick on most mms programs.anyways you said that no mms will work however all the mms installers ive ever seen work perfectly,so im trying to determine your possible problem if you claim none work.
