Is there a way to keep your browser from firmware 2.0

After downgrading from firmware 2.0 to 1.5 the browser is unavailable is there anyway to keep the browser from firmware 2.0 from totally being wiped out during the downgrading process. Tenchi browser is not as good as sony's browser.

Well, you cant have the sony browser running on a 1.5 firmware. Sorry. But a while back, on psp updates. Somebody found a way to run 2.0 apps on a 1.5. But that was a long time ago. Never heard from it again. Not sure if it was real or not.
