I'm relatively new here, I've seen upgrades to 4.2 but I need to get to 4.1 with ease.. Any easy way of doing this.... I was told I have a modchip installed (not sure which ones) but I can boot backup discs via the disc channel directly.... I need to get to 4.1 so that I can install preloader and all that good stuff...... I did a full nand backup using bootmii yesterday in case.... Is there any simple guide I can use....remember I am new at this.... Thanks.
