Hey guys. This isn't actually my problem, rather of a friend. So, he bought a PS3 to jailbreak it. He doesn't downgraded it by himselfe. He went to a Modshop to jailbreak his console. But now the problem is, he is on Rebug 4.82 CEX and wants to change to DEX. But this isn't possible on Rebug 4.82 LITE. When I tried to downgrade it to 4.81 REX, it doesn't work. I don't know why. In the Recovery options it says minimum 4.82. But I also downgraded my one from 4.82 to 4.81 without any problems. On my one it said, minimum 2.50. (I Softbricked my console, thats why I did it in recovery mode) We also tried it from the XMB, doesn't work either. No he is stuck on 4.82 and can't use Mod Menus, Webman, copy all files to a bigger hard drive with the debug settings and so on. (He tried a GTA 5 sprx mod menu, it loads up, shows the welcome message but he can't open it) One thing we didn't tried is using Ferrox 4.82. But I don't have any experiences with Ferrox. He got a PS3 Slim CECH-2504A Console.
