I have a Samsung SGH-i537
Baseband version I537UCUCNH3
Security software version MDF v 1.0 Release 2
About a month ago my phone was pushed a firmware update to 4.4.2. I immediately started having problems with battery life. It would get to ~39-50% and turn off. When I turned it back on it would be at 0-2%. The total battery time on my phone is about 90 minutes - not acceptable at all. When I look at the battery usage it shows the Android System and Android OS being the main drains on the batter, even above the screen drain.
Since this all started to happen after the 4.4.2 update I would like to change the ROM. I rooted the phone using towelroot and SuperSU method. However, every ROM I found warned against using it for the i537, so I had a rooted device with no ROM so my problem remained. I got the OTA update to NH3 which removed the root now the towelroot method does not work.
Here's what I need - a way to root my phone and get a different ROM. Anything but 4.4.2 for me at this point will work (unless there is a better fix for the battery life problem). At this point I basically have a landline phone because it needs to be plugged in almost all the time.

As a recommendation, please post any questions in the Q&A section and not the General section.
To start, if you would like to track down what is draining your battery download BetterBatteryStats and let it run until your battery is almost dead. It will show you more specifically what is killing your battery.
The first thing I would try to get the battery back under control would be to do a factory reset. This will completely wipe out everything on the phone and basically get you back to when you first pulled the phone out of the box. It should show significantly improved battery life. If that doesn't work and you still want to root, you're going to have to downgrade to NE3. To do this, download the NE3 Odin package from the Firmware Thread and load up and flash all the files EXCEPT the bootloader (if you try to flash the bootloader, Odin will fail). This will completely wipe the phone. Once you're on NE3, you can root and install SafeStrap, and then install the NH3 zip file through SafeStrap. This will result in rooted NH3 firmware.
Finally, if you want to install a custom ROM, you're going to have to go back to NE3 firmware to root and install SafeStrap. You can then flash any of the S4 AT&T custom ROMs that are based on TouchWiz. This means you cannot install CyanogenMod, AOKP, Paranoid Android, or any other ROM that is based on CM or AOSP. This is the limitation with the locked bootloader on the i537.

Sorry about the post location.
So I'm trying to get the Odin package from here, per your instruction in this thread. However, when I try to unzip to open up the files in Odin I get a checksum error; the file is corrupt. Do you have another link for the firmware by chance?

It sounds like you have a corrupted download. I would re-download the file and check that the MD5 matches the one posted on the site before you continue. If you download it and the MD5s match, then you should have not problem flashing everything. Keep downloading until you're certain you have a good download, unfortunately I don't have another mirror.

**Make certain that your reactivation lock in security settings is off before beginning this process**
1. Take the NG3 OTA update.
2. Download and install Towelroot-v3.apk(this version does not require internet access).
3. Place your phone into "Download Mode" (press and hold the Home, Volume Down, and Power keys until the phone powers on and displays warning screen, then press Volume Up key) and flash the G870A_NE4_Stock_Kernel using Odin's PDA slot(AP in Odin v3.09+).
4. Open the Towelroot app from your app drawer and press "Make it Rain" to root your device.
5. Power off then boot into "Download Mode" again and flash the G870A_NG3_Stock_Kernel also in Odin's PDA slot(AP in Odin v3.09+).
6. Download SuperSu to manage root access. Done!
Troubleshooting:
1. If the NG3 OTA update fails consider flashing the G870AUCU1ANE4_Full_Odin.tar to return to stock then take the NG3 OTA update, (or place the G870A_NE4toNG3_OTA.zip onto your ext-sdcard and sideload from stock recovery). Once updated to NG3 continue to Step 2 above.
2. The most common cause of an Odin flash failure is a bad usb port or cable. Please check before reporting a failure.
Notes:
1. After flashing the NE4 kernel your phone may run a little wonky and towelroot may not root on the first try. If that happens reboot and try towelroot once again. Once rooted and after flashing the NG3 kernel your phone will once again run like a champ!
2. The above process will not affect your User Data or Knox Warranty Flag.

Nope.
Does anyone have a list of the benefits of updating to NG3?
I just rooted my new phone on NE4 and I want to know whether it's worth taking the time.
Thanks for the How-to! Worked great for me!
Any benefits on ng3 over stock?
Root possible for 'straight out-of-the-box' G870AUCU1ANG3???
I've looked and looked around the forums here and have come to the conclusion that the AT&T S 5 I recently picked up is, sadly, unable to be rooted. Does anyone here know if this is true? As the title suggests, my phone seems to have come loaded with G870AUCU1ANG3. Is it possible that it came with the previous iteration (NE4, I think??) and I didn't avoid an update, thus meaning I can flash the earlier version? Can I even tell whether it's possible to 'revert' to NE4 (or whatever it would be)? Is any of this even possible without having been previously rooted, or am I wasting my time searching this out? Naive but earnest questions... sorry if I'm in the wrong place here. I promise, I poked around the site for a few days in search of clarity before posting.

There shouldn't be any reason why you can't follow the instructions in the 1st post of this thread starting with step 2.
I've been searching for a while and can't find anything about using this root method and then being able to install safestrap. Has anyone been successful in doing this? Do I need to downgrade before and does anybody have the downgrade file? FYI Just bought my phone last night and was successful in rooting.

Never mind, I figured it out. If you have the active you need to downgrade the kernel to NE4 like you do if you need root. Then you install Safestrap 3.75. I'm doing a Nandroid backup as I type. I'm going to re-flash the NG3 stock kernel when I'm done and hopefully that will be fine.
If it bricks, I can always take it back since I blocked the knox counter... BTW I'm on At&T
I downgraded to the NE4 to root. Along with others here I have to ask, what are, if any, benefits to upgrading the kernel?

Not sure I understand the question but I will take a shot......typically the kernel, modules, and non-hlos.bin have to match or else you may experience issues such as no wifi, lag, etc. The NE4 and NG3 kernel and modules may be similar enough that you will not experience issues immediately but they may develop later unless you reflash the NG3 kernel to match your modules and non-hlos.

THANK YOU
Working perfectly. ..thank you. ..g
There was a small update released today. Can someone that is rooted grab it from their fota/cache folder and send to me so that I can update this guide? Thanks.
WORKED! AWESOME!
Now... I have installed SuperSU. Was that left out of the first post?
Also, if I do not flash the NG3 Stock Kernel back afterwards, will I experience funkiness?
Thanks again!
Let me pre-apologize because this has probably been asked a million times already but I haven't been able to find it.
Here's the quick rundown:
I towel rooted my AT&T galaxy S5
Afterwards it failed to complete any upgrades
This led me to think the same thing will happen when lollipop rolls out
I followed the unroot/downgrade guide posted by shortydoggg
This changed my firmware to an earlier version than what I had
I now get the update notices but the update won't complete
Instead of failing at 25% when I had towelroot, it now fails at 32%
I saw a post about the bootloader being incorrect but I haven't seen a solution yet
Big question? How do I resolve this where I will be able to receive the newest updates?
OTA updates are depenant on so many conditions (file permissions, ...) That they often fail even if you didn't root your device and simply reset/reflshed the ROM using Samsung Kies. I've been there.
If you can fully wipe and reflash the ROM using Samsung kies and the OTA still fails, locate your nearest att service center (not mobile retail stores), and take it in. Show them the OTA errors out (don't check for updates for 24 hours so you can let the att rep do it and see it) and they will reflash the ROM for you using their proprietary software. This will most likely get your OTA updates working again. Their software is similar to our Odin but for some reason it also does some extra stuff to your phone that Odin and kies don't.
You can take it in and they'll flash it for you even if kies doesn't recognize your phone. Just go in and complain about the OTA failing, don't make any suggestions and let the att tech genius offer you if you wanna flash and say yes please
Oh and don't forget to backup your files before hands.
*** Your question most likely belongs to the Q&A section.

Sorry for being a little dense but there is more than one step 3.
Do you mean step 3 under the first section:
3. Place your phone into "Download Mode" (press and hold the Home, Volume Down, and Power keys until the phone powers on and displays warning screen, then press Volume Up key) and flash the G900A_ND3_Stock_Kernel using Odin's PDA slot(AP in Odin v3.09+)
Or the step 3 under the Notes section:
3. Should the NG3 ota update fail consider returning to stock NCE by flashing the G900A_Downgrade_to_NCE.tar using Odin's PDA slot(AP in Odin v3.09+) then taking the NG3 OTA update (or place the G900A_NCEtoNG3_OTA.zip onto your ext-sdcard and sideload from stock recovery). Once updated to NG3 continue from Step 2 above.
Thank you for your help
Step 3 under the notes section.
**You can begin the following process from 4.4.x Build/ROM or higher but you must already have Root Access**
**Required** FlashFire - Play BETA - PREVIEW
**Caution!** The following process is only for the I537 AT&T S4 "Active" variant. Use on any other device may result in a hardbrick!
Download:
- I537_OC7_Stock_Rooted_ROM
- I537_OC7_Stock_Rooted_Deodexed_ROM
Pevious Builds:
- I537_OC6_Stock_Rooted_ROM
- I537_OC6_Stock_DeOdexed_ROM
Set your screen timeout setting to 10 mins before beginning!
1. Place the ROM onto your device (use either internal or ext-sdcard).
2. Open the FlashFire app and "Agree" to the Terms and Conditions.
3. Press "(+)" twice to bring up the "Actions" menu.
4. Select "Flash Zip or OTA" and locate and select the ROM. Leave "Auto-mount" unchecked under the "Options" menu and press the checkmark to continue.
5. From the main menu Uncheck all options under "EverRoot" and set "Reboot" setting to "Download."
6. Press the lightning bolt then "Ok" to begin the flash.
7. Once the flash is complete and the device reboots into "Download" mode, flash the I537_OC7_Bootloader using Odin's PDA/AP slot.
The screen will turn black then display the contents of your system before beginning the flash. FlashFire will pause for about 1 minute while flashing the "system" partition. Once complete your device will reboot and pause on the AT&T splash screen for 1 - 2 minutes (15 - 20mins for DeOdexed version) before completely rebooting. Done!
Tip: for blazing fast speed turn off animations from Developer Options and reboot!
Known Issues:
- None!
Optional - Enable Native Tethering:
- I537_OC7_TetherAddOn
- I537_OC6_TetherAddOn (Flash using FF's "Flash zip or ota" option.
Notes:
1. The above process will not affect your Knox Warranty Flag.
2. The process will update your Modem, Non-hlos, System, Kernel, and Stock Recovery.
3. No need to wipe prior to flashing! The ROM will automatically perform a factory data reset.
4. To learn more about FlashFire's capabilities on locked bootloader devices see here: http://forum.xda-developers.com/showpost.php?p=60070810&postcount=2

First of all, thank you thank you thank you so much for this. Yeah I grabbed you the OTA's but thanks to you (and of course Chainfire & his FlashFire) we can go from KK to LP with root. And on day one of the OTA. Awesome. :good: So down to business, and I hope I'm not getting ahead of myself or barking up the wrong tree, but hear me out on this one. @Joe-Tech was generous enough to port his regular S4 Google Play Edition (Pure Nexus) 4.4.4 Rom over to our phone. Could we repeat that for this OC6 build, using say, this rom as a base (or another if that turns out to be incompatible for whatever reason)? I doubt I have the expertise to pull that off but if it would help I'd get to work on another masterpatch and speaker phone fix

Still loving your 4.4.4, I'm torn on taking the update if it means going back to touchwiz with no current AOSP option

Only way im thinking to boot the new LP ROM, is to use @muniz_ri method so we can upgrade and keep root. So now we going to be on the OC6 kernel and baseband, since the gpe can boot without flashing the kernel. Then we can flash the GPE 5.x ROM, either with safestrap or FlashFire, and we can also use Odin to flash the stock kernel/partitions. But too bad none of them worked for me after the upgrade, FF will sit there for ever try to get root permission.

@muniz_ri: This is great, thanks for all your work on this. As I understand it, this method will update you to OC6 with root if the original firmware was already rooted. So my question is then, if a user has already taken the OC6 update and would like to root afterwards is it currently impossible? Is the only way to root OC6 to downgrade back to NE3, root, and then follow your instructions to update to OC6 with root?
I'm guessing a root vulnerability hasn't been found for the Samsung 5.0 firmware yet, but I just wanted to check.
Also, I posted this in the other thread, but has anybody actually downgraded from OC6 to NE3 successfully? I don't want to give people wrong information.
Okay, I need some help here. I'm not quite understanding this:
1. Extract the I537_OC6_Stock_Rooted_Firmware.tar from the .rar and place it and the I537_OC6_Stock_Partitions.zip onto your device (use either internal or ext-sdcard).
Place what where? I used WinRAR to extract the file? What is the OC6 stock partition?

Correct, you will need to go back to NE3 then use towelroot before starting this process. And yes, the aboot qfuse counter determines whether or not you can downgrade. I checked it and it does allow for downgrading.

Great thanks, one more question: Would it be possible to use something similar to W0lfdroids method of rooting? So on stock OC6, flash the NE3 kernel (since downgrading is possible), root with Towelroot, the flash back to the OC6 kernel. Just thinking about it I'm guessing it wouldn't work because you wouldn't be able to boot 5.0 with a 4.4.2 kernel, but I figured I'd ask.

Any chance I can implore you to try it since there will inevitably be a bunch of people already on the OC6 firmware asking how to root it and will get pissed when they find they have to wipe their phone? Or maybe you could just provide the stock OC6 kernel and I can convince @thisisapoorusernamechoice to give it a shot?
For what it's worth, just went through the process in post 1. Everything went fine, but after the Galaxy S4 boot screen, it goes black and stays. I can boot to download mode and stock recovery, so it's not a major issue, and likely something I did. I'll mess with it a bit more then Odin back to stock and start over.

Hi everyone,
I have an AT&T Note 3 that I like to root, unlock the sim to use with other carriers, and flash a custom ROM.
Can you please help point me to the right threads or instructions to do this?
Thanks much!
Model - SM-N900A
Android version - 5.0
Baseband - N900AUCUEOC2
I just unlocked mine last week, just Google unlock at&t, go to their support page and follow their instructions, they sent me the code within 10 mins. Now on to the hard part, you have to decide which Rom you want run. You'll have to follow specific instructions for oc2 though, I'm on nc2 so mine is a little different. Just look at some of the different Roms and check for oc2. 2 Days ago I had 0 experience at rooting, now I'm rooted (towel root, super su), safe strapped, and trying to download a custom Rom now but keep getting download failed mssg. But just read about the Roms and you'll find the instructions for oc2. Good luck and post up your results.
Thanks.
From what I have read so far, I need to downgrade the OC2 to NC2 before I can root or flash custom ROM.
That's what I thought I had read once you do that is a cake walk. At least it was for me, I downloaded towel root, chain fire superuser su, ran towel, it was successful, then su, it was stuck removing knox so after about 10 min I re-booted then went into su again it brought up Knox removal again, I allowed it this time it was successful, downloaded busy box, and safe strap 3.75, (make sure you open and install busy box)then run safe strap, if it works do a back up. Then find the Rom you want, but I would try to find a Rom first in case it needs something different, so you don't waste time, I'm trying fire kat, just keep getting download failed message, hopefully I'll find the cure soon and then I'll post it up. Good luck again.
Yeah...choosing a ROM could be challenging.
Basically, I just want something that's as close to stock as possible BUT without all the bloatware and stuff. I am not much with customizing things.
Just give me something that runs smoothly and with minimal garbage.
Is that a ROM for that?
I have te same problems, Im Italian and i have NOTE 3 AT&T, Safestrap give me error : E: unable to wipe, unable to mount, why?
I have read a tutorial and i do it, now i have NC2 whit Root,busybox and safestrap.
Anyone can help me?
Ok so first let me apologize if I overlooked a similar post but I've been having root issues for weeks now and haven't found my exact situation yet.
Here's the background. I have an AT&T Note 3 N900A. When I got the phone I had no issue using towel root to root the device. Worked first try. I'm new to rooting and I was in love with all the new options. I started small playing with xposed and fonts overclocking etc. Then started researching custom Roms. Discovered cwm twrp wouldn't work with my locked boot loader so researched and got safestrap. Did the backup made my new Rom slot and with a guide I attempted my 1st custom Rom flash. FAIL. bootloop. Revert to stock Rom via Odin. Download towel root. Rooted. No problem.
2nd attempt at custom Rom flash with safe strap. fail. Download another stock firmware (at this point I was still dumb to the difference between NL1 NC2 OC2 etc). And in still dumb to oxed and deoxed. But apparently I got out of bootloop with a different firmware version this time around. First I decided to run lollipop 5.0. Towel root said device not suported. Now I'm running 4.4.4 NL1. device not supported. Also can't get kingoroot king root(pc or non pc) cf or anything else I've tried to work. From what I've read I need to go back to the NC2 4.4.2 and run towel root from there.
My current issue is I have no windows pc to run Odin on and my wife's MacBook refuses to install the Mac version correctly nor will it load the Web based version on the casual page.
I just figured out that I can't use safe strap to flasthe nc2 until I'm rooted. And without Odin to revert I'm scared to try any other method without some guidance.
First off... Is there any way to root my current 4.4.4 without going to the nc2 or if I allow my phone to upgrade to 5.o again is there a non pc root method on lollipop yet?
Or would I be able to download a nc2. Zip to my phone save to sd and use the note 3 stock recovery to revert? ?
I'm open to any suggestions you guys may have even if I haven't mentioned it in my post. Hope to get some answers asap and thanks in advance!!
I'm not familiar with the Note 3 for AT&T but Heimdall (in place of Odin on a PC) may work on your mac to flash ROMs.

Yeah I tried that a while back but it was b4 I knew this much. Maybe j can get it working now. I was just hoping there was an easier way.
