First things first revert to 3.55 OFW first before going to another CFW or it could result in a brick. I also suggest doing this via the recovery menu not the XMB. Make sure you backup your dev_flash 1-3 just in case and do a backup from the HDD utility on the XMB as well for good measure. Also make sure you format your flash drive before trying to install any FW from flash media as it can become fragmented and cause data corruption and a bad flash aka RSOD or Bricked.

And finally here
http://kmeaw.com/tmp/lv2.pkg
This needs to be ran first before Multiman upon first run but isn't needed after that. Gaia doesn't need the above file at all from what I am told but i use a manager that doesn't have lvl2 integrated so I run that file before my manager. I like this method as it allows me to choose what payload I want to run and not one that is forced upon me by the manager. I just like flexibility and this gives me more but involves one tiny extra step to boot a backup. Been stuck on FBANext for a week now so I haven't even used it
EDIT
Here are your MD5's to ensure you have proper updates. And people stop doing the Wutang/Geo CFW and doing Kmeaw as well. You are causing your own stability problems. They are two totally different CFW's Either just install Kmeaw ater being on OFW 3.55
OR Wutangrza then Geo Hot after that. Not Wutangrza then Geohot then Kmeaw!! This has been causing problems for users and resulting in errors from the end user not the devs but everyone is quick to point a finger at someone else even when it is their own fault they did not research properly before trying to go bleeding edge on technology. Kmeaw allows for 3.41 pkg's and 3.55 pkg's upon initial install and can use unsigned files. Now the reason you have to add Geohot over Wu Tangrza is the fact that it doesn't have install app enabled and relies upon Geohot's work for this, it will only install signed PKG's for 3.55. Both have flukes peek and poke intergrated one is an AIO solution that also allows for unsigned files and the other needs a little help from an outside source and only "legit" 3.55 files will work. Guess it is stil better than 3.15 users stuck with EvilNAT CFW that has no peek and poke but it can install PKG files to allow games to be ran from the XMB.
