[Q]********Lots questions on Installing NEW bootloader for 4.2 and 4.3 firmware*****
I have two T-mobile galaxy s4 M919, one is on MDL firmware and the other is on MK2 firmware.
Here is a few question I really need your wisdom and suggestion.
1. For the MDL firmware, I have simunlocked and rooted it. Also installed TWRP.
Now I am loooking to install the Omega kitkat rom v30. In its installation instruction it requires as following:
Flash the new bootloder and modems with odin
Bootloader -> BL_I9505XXUFNAD_481100_REV06_user_low_ship_MULTI_C ERT.tar.md5
If you already have the new Kit Kat bootloader there is no need to flash it again.
Modems XXUFNC9 -> I9505XXUFNC9_GSM_LTE_Modems.tar
My questions are :
1). Do I need to update my t-mobile bootloader? ( I know should use t-mobile ones). I know if updated could not go back.
2). I thinks I need to install a kitkat modem, which one should I use? Or I should just flash the KT-SGS4 - MJ5 kernel ?
3). If I just want to flash the Insane rom, do I also need to flash bootloader and flash NB4 modem?
Now is questions for the other phone.
2. For the phone with MK2 firnware s4 ( this is another Phone!), I have been following this guide to sim unlock it :
I am downloding files now. just want to make sure
1) do I need to odin back to 4.3 after my phone is unlocke with old MDL system.
2) if I want to install 4.4 roms, what should I do ?
Thank you for any of your suggestion or ideas.
