Checking just statistics does not make the dump valid. You need to manually check it too before even attempting to patch.
As you pointed out you set the switches wrong on E3 flasher. When making a dump of your flash only switch 3 needs to be up all other switches down.
When you eventually flash back patched dump then all switches are down. I'm surprised you got any dump at all never mind bad dump
This link will help you in the downgrade procedure from now on bud. Before you try anything read and read again
To check statistics should be as follows
1 - Statistics analysis
1.1 - Open your bkps3.bin in HxD
1.2 - select analysis > statistics > select your file
1.3 - mouse over the blue bars and check if:
00's - between 18.71% - 29.01%
FF's - between 10.42% - 10.48%
rest - Below 0.5%
Looks like your statistics FF's are way off
