Sorry for being inactive guys i had school and i had some consoles to repair for work
I apologise again for any confusion i had just woke up when i made this
The keys are the Caxx.cer files inside the dev_blinds.
im sure you can find some on the internet.
There is plenty of back ups on the internet, if you are on windows open in any text editor and change the serials etc.
And for the PSID method you will need to try more than once as these keys were also used back when the 3.55 cfw was released. this worked for me on geohots but my kmeaw hasnt been banned yet and this is the method i used to get on 4.31 in the first place. that may be the reason as my geohot wasnt on backed up ca24.cer and ca27.cer . I have had ALOT of messages on both NGU and psn saying rebug seems to be the one FW people have issues with at the moment. I would also like to add that i use a proxy & Diffrent keys aswell as the obvs spoofer. i dont think the proxy plays a part in this but it might do. do the same thing and run a proxy and update me to see if this method works then. im not a coding genius but this worked for geohot and my kmeaw hasnt even been banned as of 16/11/2012 at 17:10 . Good luck guys keep me updated please. Much NGU love
