So I wanted to downgrade my ps3 the other day. Currently I am on 3.50 and I own a AT90USB646 stick.
So I flashed the Hex from the PS3Yes Team and put my Ps3 into service mode.
Now I am in service but can neither downgrade nor leave it.
I made sure to put the two right files on the usb flash drive and tried it with 5 different sticks. But it would boot up normally and the red box which says i am in service mode will show up.
I formatted all sticks with fat32, tried power cycling and did everything as described in the tutorial.
I noticed that the graphics or rather the picture ist really ****ed up when it boots up into service mode, as if it was connected via an AV cable or so..
So I tried the other Hex from the PSGrade package but it doesn't even load. I end up booting in Service Mode as well.
The strange thing about it is that if I flash my board with the PS3Yes Hex it loads the contents and turns off as it should.
The next step, to plug in the USB flash drive and install the modified firmware, wouldn't work
Can please just someone give me a piece of advice? I tried all the common stuff but nothing worked.
Thanks in advance
