Why wouled u not do step 2???? That is a very dum thing not to do, first of all make a NAND backup noW!!!!!!
So if u brick u can start over from that point, (and I hope u installed Bootmii as boot2).
And sec in 3. GET A CIOS u dont have to do the trucha thing if u are on 3.2, just go to step d, (v3-3.2 can skip to step d),
d) Run cIOS38 r14 installer, select IOS36 as the one it should use and then select wad install.
Then go to step 4, if u whant to update to 4.1, ur choice. If u update make sure u install IOS60patch first then 4.1 .
Then go to step 5.
If u what preloader, ur choice:
if u updated to 4.1 in step 4 by patching first, then install preloader.
if not and u are still on 3.2, IOS60patch then preloader
after that follow rest of the guide
