PSP - upgrading firmware

[zed]

with 3.30 + the native support of 480x272 im wanting to upgrade my firmware to it.
now if i do so will i have to renew the flash setup?, or is it once enabled, always enabled, no matter how many firmware updates. (ie when u install 2.80, flash isnt enabled, u first need wi-fi to enable it, but i used a hack to enable it (not the normal method), thus im not sure if it will function with 3.30)
im releasing a set of flash apps next week, thus dont wanna lose my ability to run flash, as testing on pc vs psp is very different.

I've updated several times and each time, all of my settings have been preserved. That said, I am unaware of what your backdoor method to enable flash does. I presume you could always downgrade your firmware.

sounds good, i might wait a couple of days anyways.
+ no u cant downgrade firmware legally
