WIP feel free to make any changes to it's stage2, i can't seem to get it to reboot normally without powering off and powering back on. It's Evilnat based. also it's CEX so i had purged out every DEX conversion

So now I changed my hdd hard drive to ssd as soon as I turn on my PS3, it tells me to plug in a controller, then after to do the update 4.91 or +.
As soon as I do "start" + "select" it tells me "Verification in progress please wait ..." and it lasts, it lasts but nothing!
If anyone has a solution please

SSDs are not compatible with the PS3, and tend to break things.
