If you're looking to change OS's, you'll need full reads. Efilive only does cal reads on a40 tcm's because full reads take almost an hour, and many of them seem to be corrupt. So finding full reads to flash in is tough.
Thanks Ferm. So then I need to do it via tech 2 or J tool and Modis? I am trying to decide If I should buy a used Tech 2 or Jtool and just buy Tech2Win for a year then if i use it enough around here ill keep it if not just the 2 day subs as needed. What jTool is best?
