I finally got it to work and got the Pokebank event taken care of no problem!
I redid the browserhax (also redoing the step to initialize data after the date was set at 1/1/2000), making sure to keep the wifi off till I entered the link, got back in homebrew launcher, didn't uninstall menuhax, I just ran the install again, then exited the menuhax back into the HBL screen, and this time, I didn't exit the HBL, I just turned the power off right from there by holding the button until the blue light shut off... and then first try, got back into HBL by holding L and releasing it as soon as the screen turned to static. After that, I ran httpwn from HBL, then pressed Start to get the exit menu and pressed X to exit without rebooting and viola, went into Pokebank with no required system update. Got the event pokemon and exited and got them transferred to my game just in case.
Thanks again, everyone, I hope this info will help anyone else to get this working right.
