I replaced my trusty old GS4/i337 with a OnePlus3 and am quite happy with the OP3.
But now I have my old GS4 sitting around and sorta have the bug to play with it. I have no experience rooting, flashing, etc. but would like to see a step-by-step guide to taking my phone from stock Android 5.0.1 to Nougat 7.1.x.
While I've seen words like Odin, recovery, fastboot and TWRP, I have no clue how any of these things are related, what they do, or why they are important. So I figure no better way to learn than by doing.
Is there a guide that will take me through the process from unlocking my bootloader (whatever the first step in the process) through installing CM14.1 (last step in the process)? Make no assumptions on my knowledge. I'd rather not brick the old GS4.
I visited this page:
http://www.cyanogenmods.org/forums/topic/galaxy-s4-att-cm14-1-cyanogenmod-14-1-nougat-rom/
and this page:
http://www.droidviews.com/nougat-rom-on-galaxy-s4/
and am already stuck on trying to figure out which GAPP option to get... pico or aroma? Something in-between.
http://opengapps.org/?api=7.1&variant=pico
And go with a nightly or an unofficial?

If the phone has a locked bootloader, cm14.1 cannot be installed.
Is the boot loader locked by the carrier or by the OS? Can it be unlocked?
Once the bootloader is locked, it cannot be unlocked by an enduser. I think the bootloader is locked by Samsung as per AT&T's request as other carrier phones, such as T-mobile, Bell, Telus, and Rogers, are not locked.
Well rats. So much for that learning experience. Thanks.

Hey all. I've got a USCC Electrify M, bootloader unlocked and rooted running twrp 2.?.?> and I have a few questions.
First now that my boot loader is unlocked do I still need to flash using the retail edition files?
Next, If so do I need to use SafeStrap to do it? and is it ok to use safestrap with an unlocked bootloader?
Next, most of the roms are built from the Verizon rom, If I flash these will I break my phone due to bad build.prop, radio, and possibly other files like apn's and whatnot.
and last , if so can I use the stock files from the post at teamuscc to replace the files with the correct ones for USCC, either before or after flashing.
I know this is a tall order, but I'm relatively new to the whole safestrap bootloader thing coming from an Electrify 1 that I managed to unlock after the 2.3.5 unlock lockout, and not too familiar with the whole rom contents thing yet. Once I get a few answers to my other posts I may feel more comfortable just giving it a whirl. I do have a nandroid of where I am now, but don't want to screw anything up that can't be fixed with that.
Thanks for any info.
I was thinking of going ahead an ordering the Dev S5, but how easy is it to root a dev edition phone.
I've never owned a dev edition phone, so would it be as simple as downloading something from the app store or adb fastboot a custom recovery, then flash a root zip? Also is the bootloader already unlocked or do they just make it where you can unlock it, but it still comes locked at first? I'm just trying to figure out what the steps would be when the phone arrives to get it rooted.
Does the anyone know if Asurion would cover the phone? When you activate it, does it just show up as a Galaxy S5 or something different?
Also for anyone wanting to buy the Dev S5, you can just sell your normal S5 on ebay, and the get the Dev S5 for like $50 more, at least that's what I did.

Root is easy as it comes already bootloader unlocked. It is unlocked at the factory. To root, basically flash Odin image of a supported custom recovery (you can try Philz Touch recovery - as long as it supports the S5) or download an app from the play store which can flash a custom recovery as long as the S5 is supported. Then reboot into your Custom recovery and flash this zip: http://download.chainfire.eu/396/SuperSU/UPDATE-SuperSU-v1.94.zip
Bingo, you are now rooted!!!
Once you accomplish root, the next step you should immediately take is dd all partitions!!! I mean all!! Make a back up of all partitions!!! There are no official ODIN images available for the DevS4 or DevS5 - all images have come from the community. We have rooted our devices and backed up the partitions in case something goes wrong and we need to recover. Again, back up system, cache, radio, modem, aboot, recovery, etc etc etc....all!
Request: Once the Developer Editions are in hand and rooted. Would someone be willing to dd all of the partitions and host them? I have a DevS4 and being that I will never see an update to KitKat, I would be interested in seeing if I can upgrade using the partitions from the DevS5 (all but ABOOT).
I've this phone for a good awhile now and I followed tenfar's thread on rooting without unlocking the bootloader. A lot has transpired since I've done that and I'm a bit confused on what is the correct route for me take in order to upgrade. I have TWRP flashed also and would like to go to Lineage. If anyone could point me into the right step that would be highly appreciative.

use axon7toolkit...?
^Thank you. I wasn't aware of the axon 7 toolkit. I was able to unlock the bootloader and now running Lineage OS.
So everything is working fine on 7.1.2 which is bootloader unlocked, and Elemental X kernel to pass SafetyNet (no root) and as an app developer I want to update to Oreo (8). I plan on trying to follow the instructions to install SU Hide from the stickies, but I am concerned that I am going to screw something up. So, I ask:
When I flash O, do I need to flash the kernel as well? I assume the EX kernel won't work on O, but will it "screw" anything up if I leave it be until EX gets updated?
At the moment I don't really care about Root... Haven't used it in a while, but I figure that I may at some point, so I have left the bootloader unlocked. I have one of the fabled Verizon pixels that are supposedly un-unlockable if they get locked again, but I'm not sure if that is still true. So, the other question is, should I just re-lock the bootloader and quit faffing about with this and figure out how to unlock it again later? Or just fight with the whole process for now?
Sorry to be a pain and being indecisive... I want ALL the options..
Just realized that this was in the wrong place. I also just went ahead and winged it and it worked and still passes safetynet with an unlocked bootloader. Here's steps that I took if anyone needs them...

I've been combing the forums for a couple of weeks trying to get information about upgrading my old note 4 (Verizon, MarshMellow). I wanted to use the Lineage OS 18.1 but I can't find a way to unlock the bootloader. I've tried every method without success. None of the temp root programs seem to work. Odin gets close and then fails at the end. Same for ADB. I can't seem to get a clear answer to a question: Do you have to downgrade to 5.11 before attempting any of this? If so, how is that done on this phone? It is alluded to but not clearly stated anywhere. I'm willing to do the legwork, I just need a clear starting point.
Thanks
To unlock a device's bootloader it's NOT required device's Android is got rooted.
To flash a custom ROM like LOS you have to find a suitable custom Recovery for your device and flash this as 1st thing of all things.
Thanks for the response. That's what has been confusing. Most of the procedures I've read (some of them older) state the the first step is to temp root with Kingroot or similar. These don't work on my phone so I haven't gotten very far. Others want you to unlock the bootloader first. Same problem, can't find a way to to that in this phone that works. I'm pretty OCD so I'll keep searching.

[Official] Note 4 Verizon Bootloader Unlock
Enjoy. Don't forget to thank beaups too, he discovered the eMMC backdoor and exploited it! UPDATE: [8/2/16] I have recompiled the binary to fix issues with older ROMs like 4.4. This should fix all the issues with "This is for samsung device...

If you are using an SM-910 with a locked bootloader, like the 910V, then the answer is an unequivocal YES you must first unlock the bootloader before you can accomplish anything substantive with it, and to do that YES you must also downgrade to 5.1.1 to root it and unlock the bootloader. And your device must have a CID 15 eMMC chip to achieve any of this.
