I have 4.2.2 rom (XXUAMDE) with root and TWRP flashed. As I remember, I used CF-Autoroot, but I am not sure.
Now, I would like to test Imperium rom, but I am not sure what the heck I'm reading all about this knox and modems, and I would like to have knox untouched (0x0).
So, basically what I know now:
1. I have to flash new modem to run Imperium because 4.4.2 will not make a good use of 4.2.2 modem as far as I read somewhere
2. I have to flash Imperium which is "this manual compatible" in some way
The question is: will I trip knox with this new Imperium rom, or not? Will I have possibility to revert back to stock 4.2.2 when I decide to sell SGS4 or have a warranty repair?
PS. And if you can advice which modem, or modems (I still do not understand why there are two modems - one for phone, one for wifi, but as I read, wifi is somehow connected to LTE and I would like to update my LTE which doesnt work, but I fear I will trip knox again...)
