If yours is one of the original ones with nand memory, you can only use a progskeet. So, yes, you can downgrade that. If your fattie is one with nor memory, you can get the e3 flasher. The e3 only works on those with the nor.

Please do not advertise your website here.

It depends on when it was released, if the serial number is 3000+ then downgrading doesn't work, but up to halfway through 2500 works because the original firmware is 3.55 or lower.

Check your serial number using You must login or register to view this content. page.
