I currently have NC2, which supposedly has some security advantages over NC4 (http://forum.xda-developers.com/show....php?t=2727876). Does this mean I should not upgrade beyond NC2 or just not take an OTA update beyond NC2, and deodexed stuff posted by reputable people here are okay to flash? Also I vaguely remember having to put NC4 bands or kernel or something in when I updated to NC2 (NC4 was already out at the time). Is there an equivalent for NC5 that should be updated, regardless of whether I stay with NC2 or not?
I know roms are fine. I am having an issue because I would like to use a rom which doesn't interface with NC2.
I think my confusion comes from the term OTA. That means "Over The Air", as in "sent directly from Verizon to my phone", correct? I know not to accept the verizon updates. Is this a rom update and not firmware at all? Or at least it won't remove any capability from having NC2 installed http://galaxys4root.com/verizon-gala...dk-bootloader/
Is it just the baseband that I don't want to update beyond NC2?
I'm sorry, the different terminology is a little confusing and I don't want to do something that restricts the functionality of my phone and can't be undone.
By the way, my concern over this issue stems from here: http://forum.xda-developers.com/show....php?t=2727876
So whatever he's talking about there is that to which I'm referring here.
The Verizon OTA update is a firmware update. The difference between NC2 & NC4 is that the first was a leaked non-official bootloader. The benefits that came along with it were the ability to flash backwards to previous bootloaders, and some unique possibilities related to the kernel. Once on NC4 you cannot flash backwards, but the NC2 kernel can be flashed on top of the NC4 bootloader so that it retains all the benefits of NC2 except the ability to go back from kitkat to jellybean.
NC5, which you have provided a link to is an S4 firmware, NC2/NC4 are Note 3 firmwares. If odin even let you flash the NC5 tar it would at the very least soft brick your phone.
I would say that unless you want to go back to jellybean at some point there is no reason not to be on the NC4 bootloader with NC2 kernel as NC4 is the official bootloader, however the opinions across the forums may vary. What is clear is that taking any OTA update is unwise if you want to maintain root access to your phone. This community is full of developers that dedicate their time to providing us with a way to keep our phones as close to the way we want them as possible, for without them we would be on our own and many of us would never experience the possibilities. Thank God for devs.
I hope this helped.
