[Q] Stock Sprint SPH-L720 Slow after OTA update on 12/16/13 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I accidentally accepted an OTA update a couple of days ago that has really killed the performance of my phone G4. It' been very snappy up to this point. Apps take super long to open, and texting lags for several seconds. Reboots don't fix it, and I haven't added any new apps lately. Since the time the phone rebooted after the OTA update is when it's been having issues.
I'm assuming I'll have to root the phone, or wait for another OTA update to fix it. So, here's what I have:
Software version - L720VPUEMK2
Hardware version - L720.08
Android version - 4.3
Baseband version - L720VPUEMK2
Kernel version - 3.4.0-1927016, [email protected] #1, Sat Nov 16 11:05:09 KST 2013
Build number - JSS15J.L720VPUEMK2

Since you don't have a custom ROM and aren't rooted this question might best be asked on a Sprint Forum.
I'd be that you have a load of stuff starting at startup (account synch's etc.).
My suggestion would be to spend a few days reading through these forums to understand how to root and add a custom recovery to this device.
Then maybe install an app like Titanium Root/Rom Toolbox etc., to look at what's starting, syncing etc and then freeze or uinstall some of the culprits.
Then maybe install a custom ROM - after you've read and read a bunch.

I can root it no problem. In fact, this is the first Android device that I haven't rooted (worked pretty well out of the box for my needs!) I was just trying to avoid doing that because I just have the time to reconfigure all of my accounts, transfer data, reinstall apps, software bugs and all that crap...

[Q] Safe to upgrade my system after rooting?

Greetings,
The first week or so S4 was out I had gotten one and rooted it. Not very long after that a 'System update downloaded - touch to install' has been on my phone. Many many months later I have decided to finally ask if it is OK to go ahead and update my system and if not to the latest update, then to which? And if I can let my phone automatically do it or if I need to be careful.
I'm afraid I don't remember how I rooted my phone. It was a 1-click exe I believe.
Here is some information that may help.
Android ver: 4.2.2
kernal ver: 3.40- Sat apr 27 2013
software ver: L720VPUAMDL
Hardware Ver: L720.08
Please let me know if you need more information to help me.
Thanks!
You can't take ota updates without breaking root.

IF you take the over the air - OTA update you will be stuck on the MK2 bootloader and will NOT be able to got back to MF9 or earlier if you want/need too. You will trip the Knox counter - read a little and you'll find out what that is; it's been discussed ad naseum..
You can update the firmware without the Knox bootloader as mentioned.
Decide if you care about the Samsung warranty (if you trip the Knox counter you may not be able to have Sammy warranty your device; though Sprint probably will).

New to Flashing, Want to install Eclipse [Note 3]

Hello everyone.
Is there a one true guide to installing a ROM on my Note 3? I'm running a T-Mobile N-900T. It seems that after browsing the web, I've seen so many different ways to install a ROM that I'm extremely hesitant to try one on the off-chance that it is no longer supported and may brick my device. This is a non-warrantied phone (bought it on Swappa) so I only get once chance if I end up Hard Bricking it, so my fear level is at the absolute highest.
I wanted to run Eclipse Note 3 TW Rom (found here: http://forum.xda-developers.com/showthread.php?t=2620723) because it's a nice simple ROM that retains S-Pen function and removes all the bloat and stuff. However, I noticed that it says "This is based off of 4.4.2 NC2 for Verizon Wireless." Does this mean it won't work with a T-Mobile Note 3?
This is as far as I got in towards the process before I stopped due to something unexpected:
1) TowelRoot. Rooted it and confirmed with the Root app that it was indeed rooted.
2) Downloaded SuperSU. I installed the binary using the Normal mode since I didn't have CWM or TWRM at the time. It asked me to disable KNOX and it looks like it was fine. I restarted it.
This is where I stopped. After I installed it, it asked me to confirm if I want to confirm allowing Freedom and SetCPU. I did and it continuously started spamming the notification that it was allowed for 20 minutes.
I went into the SuperSU program to see what's wrong and it then told me that the Binary could NOT be found and that I may have to flash my rom back to get it back to normal. It then gave me the error that something was wrong on my phone and that I might have to install something called Samsung Kies to make it better.
I pretty much freaked out at this point and de-installed SuperSU out of fear that I might screw up my phone. Now I'm extremely fearful to do anything without seeing some sort of de facto guide on what to do next.
If it helps, here's the phone information I have. I know that different ROM flashing methods are used for various kernels.
Model: SM-N900T
Android Version: 4.4.2
Baseband: N900TUVUCNB4
Kernel: 3.4.0-660648 | [email protected] #1 | Wed Feb 12 21:31:27 KST 2014
Build Number: KOT49H.N900TUVUCNB4
SE for Android Status: Enforcing | SEPF_SM-900T_4.4.2_0005 | WED FEB 12 21:31:01 2014
Security Software Version: MDF v1.0 Release 2
I have a 128GB Samsung SDXS MicroSD. The phone recognizes 119 GB of it which I know is normal.
Any help or direction would be most appreciated. The world of Flashing has so many roads that my head is spinning and my fear is that I will turn this phone into a $500 brick because I followed the wrong guide.
Thank you.
Best way of flashing a new rom is using "Odin".

Thanks.
I do understand that and I have the program, but I can't find any SOLID documentation. I see all these different guides out there and I'm scared that I'm going to pick the wrong one. The ages vary as well, so I don't know if they are still relevant or not.
Not only that, I don't believe that just Odin is enough. There are also prerequisites that are required before I can just up and use Odin. That'st he part that I would hope a decent guide out there would provide me.
A bit early by a few minutes but, Bump for help.
Any information or leads would be terrific.
Thank you.

[Q] Rooting Note III Question

Yes, this has probably been gone over ad nauseum throughout the site. Due to time constraints I cannot dig through the forums as much as I'd like, so I'm simply going to ask.
Phone: Samsung Note III (SM-N900V)
Carrier: Verizon Wireless
OS Version: 4.4.2
Baseband Version: N900VVRUCNC4
Kernal Version: 3.4.0
Build Number: KOT49H.N900VVRUCNC4
Hardware Version: N900V.07
It was purchased November 2013 with OS 4.3. Over the summer I accepted the OTA update to 4.4.2. My phone went to hell. Battery gets chewed through like a woodchipper, phone is horribly laggy, antenna connection is always 1-2 bars under where it was prior to update (and doesn't get reception in areas it did before), changes to the UI are less than desirable, etc.
The phone was never rooted, as this was the first phone I've ever had that worked well enough on stock software that I skipped it.
After giving it a few months on the update and trying changes/tweaks within the updated stock software to fix the issues the update caused, I'm at the end of my patience. Contacting support at both Verizon and Samsung was pointless, with one blaming the other for the problems.
What I'd love is to take the OS back to 4.3 and leave it, but in lieu of that I want to root the hell out of it and put a build on without these issues and a better antenna software. I'd prefer not to void the KNOX, but at this point I'd microwave it if it'd help.
I have no backups or root access from before the update to base a root on. I tried towelroot; install button doesn't work and I understand the maker Geohot works for Google now. I started to play with Odin, however the install seems to have an oddly high amount of other software it wants to install, and even after declining those it doesn't want to install (tried 3.09 and 3.10, I'm using Windows 7 w/latest SP and updates). Also, it drives my AV software crazy, so even turning that off and working with it didn't get me very far.
So, at this point, I'm open to most anything to get this crap off my phone, and my only requirement is that I don't brick it.
Options?
Thanks in advance for any help.

This is the best breakdown of what you need to do. Click here, scroll till you see the blue outline for NC4 OTA.
Be sure to hit "thanks" on @az_biker link for this tutorial!
Unfortunately this won't work, I've already tried. When running the towelroot installer the Install button is not clickable. The other buttons function normally.
Op did you ever hey the note rooted....did you get the towel root to work

No to both, unfortunately.
I've had no issues with towelroot. But for giggles make sure you have install from unknown source checked, and then unlock your developer options and make sure USB debug is enabled, then give it another shot.

did you take a ota
I have not, since the leaked NC2 firmware was leaked out. However on my s4 I just used towelroot with the latest NC5 firmware, and it worked flawlessly.

[Q] Not sure if I can re-root

Hello,
I have a Verizon SM-G900V,
Version: 4.4.4
baseband: G900VVRU1ANK7
Kernel Version: 3.4.0 [email protected] #1
Build number: KTU84P.G900VVRU1ANK7
Hardware: G900V.05
And I had my phone rooted but the updates kept popping up and I wasn't sure how to disable them. I have platinum backup but I just read about "Freeze" option. Unfortunately, I can't use it anymore because I don't have root access. I think my phone partially updated, for the 5.0. It did restart and optimize some settings but I can't use the playstore anymore, and I don't have any SuperSu.
I'm not sure if I should just go ahead and update it since I don't have any other option to use the play store, or is it possible if i can just re-root it based on the 4.4.4?
This was my 1st time rooting it, I used to have an iPhone so I tried to supply as much info as I could.
Thanks!

Help unlocking, installing stock ROM on an S5

Hi, a friend has a Galaxy S5 (MetroPCS) he wanted me to unlock. He works at a hotel and any items found in rooms go to their "Lost and found" thing for a 60 day period. This was found and never claimed, so he wants to use it as his own. I've looked through it a bit and it appears it was used by a former drug dealer around town. Huzzah. Anyway.
It appears to already be rooted and has TWRP already installed, though still uses the stock ROM.
My questions are- How would I go about doing a fresh install on it? Also, is there a free way to unlock them or do I have to go through one of those unlock websites?
Here are the specs

Edit: I found this site, http://samsung-updates.com/device/?id=SM-G900T1
I see there's a newer version with 5.1.1. Would I be able to flash that without any major issues instead of the one already on it?

Upgrade it using Smart Switch.
Just an update- I successfully used SmartSwitch to upgrade the phone, kudos for that.
Also ended up going through cellunlocker.net to unlock it. They even sent an unfreeze code with it.
