So, as the tittle says, can someone Break this down for me? I have read and as example, there are different versions of those files, and the state that they can be installed on sysnand and some others on emunand... so.. just o break it down in a couple of questions, and please keep your answer simple, don't need anything technical, just a logical explanation as example, what does it do, and where does it go. So: What is AGB_FIRM-PatchedV1-0004013800000202 for? Does it go installed on Sysnand or Emunand? What is TWL_FIRM-2.0-0004013800000102 for? Does it go installed on Sysnand or Emunand? What is the difference between TWL_FIRM-2.0-0004013800000102 and - TWL_FIRM-4.0-0004013800000102?
