Yeah. If you update to a OFW then you will have to do the process of rehacking the PSP. And yes it works all the same if you make the pandora battery. I made mine. Its all the same. Just dont update to the OFW anymore, switch it so that instead of updating to OFW it will just upload to CFW. Problem solved. And if you think your going to do that again then just keep the pandora in a box or something with a MMS that all ready to go and that will make it hacked once more. Thats what I did like 2 times because the new PSN update for the movies and TV wasnt on my PSP so i assumed you needed OFW for it. So just keep a pandora and ready to go MMS somewhere. Hope that helped.
