Current ROM on my Note II is Jedi X20. I didn't update to the official 4.3 yet so no Knox. I know that going from 4.2.2 (TW) to 4.4.2 (AOSP) on the S4 without updating to latest official will give data issues. Is this the same for the Note II? Will flashing a 4.3 TW or 4.4 AOSP ROM give me any data issues if I'm coming from a 4.1.2 ROM? (I don't want to update to official 4.3 due to Knox)
