Hello everyone. I wanted to update my RGH Console from 16202 to 16537. But i faced two problems: 1. After I obtain the flashdmp.bin with SImple NAND Flasher and put it in xeBuild it gives me this - http://s7.directupload.net/images/130914/27mnjvro.png 2. The CPU KEy - it starts with BAD036B0D5C9... and when i read the cpu from cpukey.txt it gives me an error that it is a corrupt key. Will it be possible for me to somheow update my Console? If I remember, I have an RGH2 / Corona 4GB Thank you!
