You can either update using a disk game, or get the addresses needed for dimok to add support to your firmware in the next release of loadiine GX2.
For example :

dimok said : " Another thing needed for "a good support" on other firmwares is a dump of memory addresses, which are free for our RPX load up. I wrote an app for that and it just needs to be run once, but before that the addresses above are needed to make loadiine work at all."
Just ask
@ptitleray he probably already went through getting the addresses for an older firmware using Dimok's app.
If you don't want to do through all this hustle, then buy a game with 5.3.2 update
