Note 4 Issues When Flashing Roms, Please Help - Galaxy Note 4 Q&A, Help & Troubleshooting

My younger brother has a Note 4. It was previously on Kitkat 4.4.2, stock rom, rooted with dual recovery...
He wanted to manually update to either a 5.1.1 Lollipop rom or even 6.01 Marshmallow.
After having tried several 6.01 roms, the phone either bootloops or the sim card is not reading...
After having trying to flash the radio & bootloader to flash via odin, it keeps failing when trying to do so.
Could someone please recommend a simple Lollipop rom or Marshmallow rom that actually WORKS and the sim card is read as it should?
With my current Sony Z2, it is so much simpler, flashing any roms automatically comes with the kernal, radio, recovery, root, etc...
With Samsung it is much more complex and finding a rom which comes with everything seems difficult to find.
Some roms even ask to choose a kernel & modem/radio. How the F**K do i know which one I need? Even when selecting one it results in a bootloop.
I'm not interested in overclocking or using a custom kernel. I just want something that works and any 5.1.1 rom or Marshmallow rom would do. I want something as close as stock as possible. Not interested in Cyanogen mod, custom roms or such.
Thanks!!

you need to flash a compatible modem for your model number and version of android. If it helps, I'm using: N910FXXUICOL2 with Marshmallow
I have the N910F model.

Hmm, I don't know why you are having problems, actually its Samsung where you can simply flash a ROM with Odin, no need of ADB or anything.
You just make sure that you COMPLETELY WIPE your phone before flashing a stock ROM via Odin. You should not have any problem at all, no one should, unless its hardware.

[Q] help me understand the root world a little more

I'm trying to learn more about the S5 root world. I am currently running the OTA NHA build, and am rooted using towelroot, and have the latest safestrap installed (also have supersu and busybox). What i am trying to understand is how the custom rom's work now. I just got the S4, and never had my bootloader locked since i rooted/rom'd earlier on and never ran stock, and i was using TWRP so there were no rom slots or the like; you downloaded a rom, wiped your phone, flashed it, done.
This bootloader/kernel/baseband talk is what's confusing me. A question that i've been trying to find the answer for is as such: let's say i have my NHA rooted phone, but there is an NE9 rom on the forum i want to try (extreme syndicate/alliance). Can i just flash that to a rom slot and go, or do i flash the kernel as well? if i flash the kernel, won't that mess with my stock rom, or does that just patch the kernel inside of the rom slot?
I already understand that chronologically, the baseband/build versions are NCG>NE9>NHA>NI2, so understand that rom's baseband is a version behind NHA. Someone please help clarify some of this for me

[Q] Messing with ROMs on UCUFNB1

Hi everyone. My phone is rooted and has Safestrap Recovery. I've been anticipating the Android L update for some time and have been used the better part of my weekend trying to figure out how to get that experience. However I'm near my wits end and thought I might as well just ask the experts.
Has anyone tried or know of any way to try out the new update? I've tried a Cyanogenmod 12 rom with the Safestrap Recovery on a new partition or "slot" with no luck. I'd prefer some method that'll let me flash a non-stock rom so I can have the ability to tether (I'm on a T-Mobile sim card with an unlocked phone).
Any advice would be greatly appreciated.
I have also tried a Lollipop ROM, specifically the GPE one, with no luck. We unfortunately cannot use Cyanogenmod, due to the locked bootloader which prevents using custom kernels (SafeStrap is like a workaround, with some limitations). It's only a matter of time before the official Lollipop update rolls around. By then, there'll hopefully be a Safestrap-adapted GPE 5.0 Lollipop ROM.

HELP PLEASE ! want to upgrade from 4.2.2 to Lollipop

Hey Everyone!!
Thank you for looking at this thread.
In a nutshell, I got my i9505 galaxy s4 since June 2013, rooted it straight away when i got it, its got twrp recovery, and im on omega v9 4.2.2. Havent touched it since to date
It does not have knox.
Is there a way I can simply upgrade to something like cm 12.1 with 5.1.1 with everything working, by simply flashing latest cm with gapps using twrp, or will I have to upgrade bootloader, radio, get knox, or even just start over, flash stock samsung lollipop firmware with knox using odin, in order to do so?
I already a while back tried updating twrp to latest, and tried flashing cm with lollipop 5.0 when it first first came out, but only 2g was working, and signal would cut if i lock my phone. Im guessing this is due to bootloader/radio incompatibility, or maybe because it was early builds? Apparently i cant flash lollipop bootloader and radio over old 4.2.2 stuff without consequently installing knox? Is knox that bad? I heard its better to not have knox but if its the only thing stopping from lollipop then so be it.
Any help and advice much appreciated.
Hope to hear soon,
DJ
You can try upgrading just the modem to be able to flash an Android 5.x ROM, but it likely will not work and thus you will have to flash an updated bootloader as well. The good news is that since your S4 is out of warranty, whether you trip the Knox flag or not will not matter.
You should be able to flash the updated bootloader and radio without having to install an entire ROM, though you might want to download the latest ROM for your S4 anyway. There is a thread in I9505 General that has a list of bootloaders and modems that can be downloaded and flashed through Odin. From there, you should have no problem flashing the custom ROM of your choice through recovery.

A little help, please.

I'm coming from 4.4.1 I want to flash a Lollipop ROM, I haven't flashed for very nearly 2 years. I'm obviously rooted already.
Is coming from KitKat as simple as just flashing a Lollipop ROM? I'm an SM-9005, I've got Odin 3.10 and I want to flash Resurrection-Remix-LP-v5.5.5.
I've seen that I need to backup my PIT and obviously backup my current ROM, do I need to update my baseband or radio etc?
No one?
No need to backup your baseband or radio. RR is an AOSP ROM as far as I know, so you won't be able to flash it with Odin I'm guessing, as it comes as a zip package? I don't have any interest or idea about it, but you can only flash via Odin if the ROM comes as tar image.
Also as you are coming from KK, you 'might' need to flash a stock Lollipop ROM first to update the bootloader from KK to LP, read RR topic, see if its mentioned or not. If its not then you probably don't need to, but as I said no idea.

OK2, Android 5.0.1--what are my options?

I currently have AT&T stock (I used to have a custom ROM then had to flash to stock ROM to be able to flash to another custom ROM--however, I accidentally flashed a newer version of the AT&T stock ROM which locked my bootloader and I could no longer flash to a custom ROM). I updated my AT&T stock ROM recently and now my back/menu buttons don't work, so I want to see if I can flash to a custom ROM now.
I don't remember the procedure to flash a custom ROM--do I first need to get root in order to unlock the bootloader to be able to flash ROMs (i.e. if I have root then I am guaranteed to be able to unlock bootloader in order to flash ROM)? Is the baseband version the only thing that determines whether I can unlock the bootloader and then be able to flash ROMs?
I currently have OK2 as broadband version and checked one of the stickied threads which said this:
" ROOT
OK2 -- No direct root method. Must Odin OC4 kernel, use Kingroot, then Odin OK2 kernel back."
Does that mean what I have to do is use Odin to get OC4 kernel, then use Kingroot, then Odin OK2 kernel and then I will be able to have root, which means I can then unlock my bootloader and be able to flash to ANY ROM (not just TouchWiz-based ROMs)? Is there anything else I need to consider or is this 100% foolproof? In the future, what should I be careful of in order to prevent getting my bootloader locked again--just that I don't flash a stock (AT&T) ROM that is known to lock back the bootloader?
Thank you all!
There's no way to unlock the bootloader if you have updated your device to the lastest firmware version. The only thing you can do is flash SafeStrap and use Stock Kernel Based ROMs which are compatible with Safestrap.
As regards to the procedure of rooting an OK2 firmware, I'm afraid I won't be able to help you.
Have a happy new year.

I was just about to sit down and flash a stock ROM. Can you explain what you mean by this? Did you flash OK2 and it caused you a problem?

It was a while ago but I used to have I believe an MDL broadband version which meant I could flash any ROM available. I tried a different ROM, didn't like it, then decided to flash back to the stock ROM but accidentally flashed a newer version of it, which meant that my bootloader is now locked. With a locked bootloader, apparently I can only flash to a newer stock ROM (not other ROMs like Cyanogenmod) via Safestrap.
I think if you don't have the MDL broadband version you shouldn't worry about it anyway because it is locked and you will only be limited to flashing stock ROMs.
Slight correction
The previous entry is not entirely correct. Like the OP, I was originally on an unlocked bootloader on my i337. I'd purchased my i337 on the first day and eschewed OTA updates. I wanted to try a touchwiz based ROM, Hyperdrive, and in doing so I recall flashing the stock NB1 firmware. Every firmware beginning with NB1 has a locked bootloader and there has been no progress for more than a year in unlocking the bootloader again. This can limit you to either stock ROMs OR other touchwiz based ROMs like Hyperdrive. I love the Hyperdrive ROM (now on release 21) but its developer has moved on to a newer phone, so it's stuck at Android 4.4.2 and no one has picked up the project in many months. There are several other touchwiz based ROMs for the i337 version of the S4 which I have also tried but I prefer Hyperdrive's myriad customization, even without proper patching. I'll be moving on soon to the Nexus 6P as my daily driver, but would very much like to keep my S4 up to date with a custom ROM. Given the number of people that have been in this same situation, where a newer stock ROM from AT&T locked a previously unlocked bootloader, it's been surprising that the issues have not been overcome on a phone as popular as the Galaxy S4 was and continues to be. I've seen unlocked versions of the S4 selling for just under $400 in the last week of 2015.
Use the desktop version of Kingoroot to root and use Super su and update the binary. Don't forget to hit thanks if this helped.
The bootloader for the at&t s4 was never unlocked. The MDL bootloader had a flaw in it that allowed you to use LOKI which is a lock bypass, not a way to unlock the bootloader.
