Galaxy S5 wont downgrade? - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

Hey guys i have a Verizon Samsung Galaxy S5
SM-G900V 5.0 Lollipop
Kernel 3.4.0 Friday July 31 2015
Knox 2.3
I just tried to downgrade to start the rooting process and i cant get Odin to pass for my phone, I put the code into Odin, put my phone into download mode, and hit start and it failed multiple times. Ive read Geohots thread but i cant find the actual root process and many other threads, can anyone give me a link to the actual process for my phone to be completely rooted or reply with the process? im just starting out getting into modding my phone so take it easy on me with the lingo and abbreviations lol

Go to Settings -> About Phone and look at the last 3 characters of the baseband or build number. If you are on OE1 or OG5, you can't root. Return your phone and say the software is unusable due to lag or make up some other excuse, or go get a different phone. This is assuming you just newly got the phone.
I have no idea what code you're talking about. If you do NOT have OE1 or OG5, follow this guide and start at step 4 in the NOTES section (because you do not yet have root).

Yeah its OG5, ****... what makes it so it can't be rooted? And the code I meant was the NE9 code from XDA but I guess it doesn't matter now

Verizon locked the bootloader. You're screwed, dude.

Noob Here Needing Some Pro Advice

So my friend told me to root my new Samsung Galaxy Note 3 (Verizon), but I am a complete noob and do not want to mess up my new phone.
He told me to be careful so I don't brick my device, and too read the forums. I have spent all day reading the forums and still don't know what I should do.
I saw a video explaining how to get root by going to towelroot.com, but this seems too easy to be true and safe.
Can I get root and not have to worry about bricking or tripping knox with towelroot?
If towelrool is ok to use then I will just go ahead with that, but If there is something better, could someone please point me in the right direction with what I need to download.
Thanks for any help and here is some of my device info if that helps...

For those of us who took the OTA, ... That app http://towelroot.com/ is the only exploit that provides root access for VZW N3.
yes. i am going to sound confusing now so hold on...Towel root is what it is... download. install. click.. your phone will reboot with root access ... it is a one click method... however, the bootloader and recovery is still locked on your device, and if you try to install CWM or TWRP, at this time you will trip KNOXX and void your warranty. Install SafeStrap instead from here : http://forum.xda-developers.com/showpost.php?p=53701934&postcount=1298.. then flash only one other file from this post http://forum.xda-developers.com/showthread.php?t=2760380 thanks to the DEVs that have been working on this the whole shebang seems almost too simple, like you said... i agree.. i did everyrthing in that post as i installed Jasmine Rom. why? because the DEV is kickass, with the updates, i like the S5 themes, and its pretty simple to set up compared to what you've probably read up on..
and its really close to stock, which, of course, ive tried out a couple of other roms since then, and it still works (the phone)
Regarding KNoXX , your device will still read 0x0 , but it will say "custom" status .. you can fix this
if you root your phone and your status says "custom"..a flashable zip file here will fix that http://download.chainfire.eu/supersu you can find links to Safestrap, "unified files" and step by step instructions at http://forum.xda-developers.com/showthread.php?t=2760380 some more on what i mean by "custom" http://forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114 This does the same , maybe better http://forum.xda-developers.com/showthread.php?t=2473938
Towel root will not "hard brick" your phone ,,, meaning your phone is basically an expensive paperweight... ii gave you thseds links because its what worked for me... however, you know whats best for you..

broken root during update. how to unfuxor?

so I mistakenly pressed update few months ago when the update came out.
phone was rooted with towelroot
I also have superuser and supers installed
and triangle away
none of them are functional because of the failed tmobile update.
whats the best way to fix this?
im trying to keep the settings and info in my phone if that's at all possible..
I know I can just start over and load a whole new rom on it and then update but I have settings and apps I don't want to go through the process of installing all the apps and changing and trying to remember how my settings were ive had enough of that fun when I had HD2 with android port.
since that time I just want stock rom that works stable.
You can go to the T-mobile Development Forum and use ShinySide's root method for FOF6 (assuming that is the LP rom you are on).
You will trip knox though. Currently, there is no way around that on Lollipop, unless you want to try and downgrade to 4.4.2
what if I reinstall original OS.
I'm not sure if its rooted or not. or kinda stuck inbetween.
my android version says 4.4.2
I tried towelroot it says phone not supported
I try tmobile update it says cant update.
root check says its not rooted...
superSU is stuck in the middle as well.
I don't get it
I root the phone with odin
everything goes good it says reset then says pass
then I check with triangle away says system: modified counter:zero binary:custom etc
the phone is stuck inbetween root and update and it wont let me do either.
I can't root or unroot or update.
not sure wat is goin on with this crap
I really just want to unroot so I can run the update and then root again.
I'm not sure what is happening now with this phone it wont go either way
or maybe just load the updated tmobile stock rom whatever works honestly.
Hmm....The words 'rock' and 'hardplace' come to mind.......
Apart from the failed update, and the lack of root access, is your phone functioning normally?
If it is, go to settings >> about device and check which firmware the device is currently running.
Then go to one of the firmware download sites and get a copy of that EXACT SAME firmware.....(This is assuming it is still running 4.4.2)
Pretty much the only thing you can do at this point (if you want to keep all your settings etc) is to odin flash to an identical (but unrooted) system 'state' that you had before the failed update borked things on your device. Then you can follow the steps needed to towelroot your device......If that involves flashing an older kernel before towelrooting and then flashing back to your pre-existing kernel afterwards, then you (obviously) need to source them too.....
If it is your intention to update to Lollipop and then attempt to root again, I'd think again if I were you.....A lot of users are reporting that it's damn near impossible to root the latest LP firmwares.....even with CF Root......
You'd be better off rooting on KK, then using Flashfire to flash Lollipop and get it to inject root while it flashes the firmware.

What is the build date on the installed firmware, if the build was compiled after July 1st last year, you need an older kernel in order to towelroot (at least this was the case for me when I towelrooted)

I used towelroot when I root it first time right after I got the phone. and then my dumbass forgot to unroot it and clicked on the update when it popped up...
Lol....easy enough thing to do......
It's the kernel that has to change to allow towelrooting......
When I towelrooted, my firmware was ANG2......I had to odin flash ANE2 in order to get towelroot to work (and then flash back the ANG2 kernel).
The kernel for your device will be a different version number, but you get the idea.....

this hurts my head. i still get flashbacks from HD2 android port and trying to keep up with all the new and improved builds...
the part of my brain responsible for cellphone modifying is burned out after that.
since then i just look for easiest root method possible until this happened...
what exactly do i need? im gonna try to process it on my own for next day or so
There are 2 prerequisites for using Towelroot........
1) your system must be running KitKat.
2) the build date (specifically the kernel) has to be before 1st of July 2014.
You mentioned that the kernel you have said November 2014 (?) therefore, you have to find a kernel that was compiled before the end of June 2014.
You ALSO have to find a copy of your CURRENT kernel.
Once you have both of those, the procedure is very straightforward.....
1) Odin flash the OLDER kernel (this is likely to cause some system instability....don't worry, that is to be expected)
2) Install towelroot and root your phone.
3) odin flash your CURRENT (November (?) 2014) Kernel. ........
Job done.
Then, rather than OTA to upgrade (this will break root), use Flashfire and get it to root the upgrade as it flashes it......

ok ow I got it. thanks
I found some page
NF6 - NG3 - NG4 - NH5 - NK2
but everyone always assumes that people know what all this crap means lol
all I know is nk2 is the latest kernel on 4.4.2
and nothing about the other abbreviations.
I look for kernel version and google shows nothing
Just flash a pre June 2014 KitKat ROM, forget about Kernels

I just visited samsung updates dot com (we're not allowed to post links to the site) and found a section called 'compatible kernels'.......
I put in the search box 'SM G900T' (I assume this is your model variant) and it came up with a whole list of kernels.....
The ones compiled BEFORE the end of June 2014 are.......
NF6, NE6, NE5 and NCH
As I understand it, you *should* be able to use any of those for towelrooting......
Just remember to get a copy of your existing kernel while you're at it so you can flash back to it after rooting....

fuuuuuk
you know I just remembered why I threw away my HD2 and stuck to unmodified rooted phone for last 5 years.
because its a fkn nightmare with all the people posting same **** in 300 different ways and having links to essentially same fkn file just named differently
4 hours later a folder full of kernels and who knows what roms I downloaded.(because they are all hosted on slow ass download pages and I don't know which one is gonna actually download and not break and start over download again)....
I'm still in the same spot.
knox is tripped and new kernel with still same KitKat rom
i managed to root and unroot the phone but now its not downloading the update because knox is 0x1
time to sell this crap and get newer phone and forget about this rom **** for few more years.
I'm done. I really hope XDA can someday manage to clean up all this fn confusion about roms and make is simpler for people who don't spend 5 hours a day loading and reloading roms like I did with hd2
keith I really appreciate your help. its not your fault but this page is like a fn black hole.
the problem is all the damn garbage and misleading info that you find on google. which is confusing as fuk.
i don't understand why do i need to load older rom again if i want to update to 5.1.1?
If you're not worried about your data or root access then upgrading to 5.1.1 is as simple as a single odin flash......
If you want to keep root then downgrading, towelrooting, then upgrading with Flashfire is the easiest way to go......

Has anyone been able to ROOT their SM-n910v Marshmallow 6.0.1?

Build MMB29K. I've tried and can't get TWRP loaded on there. I just bought this phone, but thinking about sending it back and keeping my rooted Note 3 if I can't get this to root! Here is the partial link to my post on Reddit about this same topic:
galaxynote4/comments/52my2m/has_anyone_been_able_to_root_their_smn910v/
Still no solution. Please help!
Same here
Can't get Odin to write the bootloader successfully.

Right if u took the ota you are locked as far the bootloader goes ....flashing will not be possible til this is corrected ....im told u can odin back to 5.1.1 which has a pretty easy method the safely upgrade so rooting and unlock are simplified. I never tried to rooting from the stock firmware.... does kingroot ever get u rooted? If so the u could try the aforementioned method but u would need a 6.0.1 compatible kernel (Sprint) given u r on there dev cid .
in the verizon note 4 form is where you should be looking because you have a locked bootloader.

Help rooting S5 (SM-S903VL)

I'm having issues obtaining root on this device. I'm not sure if the bootloader comes unlocked or not. I tried kingroot, iroot,framaroot and few others. None have succeeded. I even tried the chainfire method in Odin and it fails every time. I've read downgrading is an option but from my understanding is that on a locked bootloader you can't downgrade. Attempt to ends in a hard brick. So correct me if I'm wrong. So after all is said anyone know how to root this thing? It's becoming quite frustrating.
anyone???
Bump

bump this phone is so locked down...
from what I hear. A member here is working on the testing firmware. From my understanding, it's the firmware that was first put on this model to do testing and it runs 4.4 Kit Kat. The problems in it is a whole load of things including no cellular service. I think they have all things but contacts working correctly so far. Oh and best part is your able to root on the test firmware but people need those bugs worked out to have a stable usable phone. I tried things more simple like the Kit Kat firmware from the sm-902l model. It's still an s5 that runs on straight talk but different model numbers obviously and it runs 4.4. So I thought give it a try but Odin fails it every time
Any update on rooting the phone?

Question regarding Rooting and Flashing GS8+ CRk1 Baseband

So im wanting to finally root and flash my phone after having it for almost a year, tired of all the VZW updates, prompts and just general bloat. So i did some digging and samfail only works up to V5 bootloaders.. my phone baseband is g955usqu5crk1 and i cant find any info on it and i dont want to try to do samfail and brick my phone due to it not being compatible. Does anyone have any info on this version or know what i can do from this point?.

I am not sure, but I think you can still root. Check the ROM section here in the Verizon Forum and look for JRKRuse thread. Or, look in the S8 Plus Forum under ROMs and look for the Partcyborg thread. I think with the S8 plus you can still root V5, but check with the experts before you start down any path.
The 5 near the end is bootloader version 5, the C means Oreo
Im on the same baseband version and have been trying samfail method all night, as well as different odin versions, i either get sha256 error on first step or else it hangs for way too long
I believe there's a patched Odin which helps with the errors you're describing. Google (patched Odin 3.13.1). It combines features from the Odin variant (Prince Comsey Odin) which eliminates such issues.
