[Q] Need to hotspot from unlocked, rooted Galaxy S4 Active

Hi. I have an AT&T Galaxy S4 Active which was (supposedly) factory unlocked. It does accept another SIM so I know it was at least partially unlocked. I have also rooted the phone thanks to your help here. (Big thanks for that!!!) But I would like to be able to use the phone as a hotspot and can't seem to get it to perform. I get an error message that there is a network error please try again later. It occurred to me that this might be due to the AT&T APN still being listed as "default", although I have entered my carrier's APN info.
Is there a way to remove the AT&T APN? Or, alternatively, does anyone have another trick I might use? Any and all assistance would be greatly appreciated!

Is your phone sgh-i537 ?
We have several of those and all are unlocked. They arrived (large shipment) from vendor, all rooted with a locked down android 4.3 (ML2) and mobile hotspot would not work......system update would not work....
Here's what I finally did:
1. Installed Odin 3.09
2. Downloaded full image (1.2 GB) for ATT ML2 (Android 4.3)
3. Reflashed over *existing* ML2 the official ML2 which killed root and any other customizations (desired!)
4. At this point, connected to ATT System Update, it found automatically the 444 MB update to Android 4.4.2
5. Rooted with towelroot.com
6. Hotspot works now fine on all of them.

Mine is an i537 and I`m in almost the same boat. I can not enable a wifi hotspot. My phone was originally branded AT&T but I am running it on Wind which uses AWS frequency like TMobile. My phone is rooted with towel and the radio file has been modified for AWS.
Can I do what xdafly said but still modify the radio file for AWS? How about the 444mb update from AT&T? Can I update that way even tho I'm using a sim from another provider? Is there a file I can download with the same update in it?

Unable to comment on the radio file but perhaps someone else has more details on that and will post.
However, as to your question on the 444 MB update, I also tried on a few of our i537 the download links found in the ATT Stock Firmware thread
As you will discover there, if you have an unmodified ML2 (Android 4.2) or WISH TO make it so, you can install Odin (links are there) and you can download the ML2 image (links are there) and THEN you can download the 444 MB file, place it on a microSD card, drop into Stock Recovery and select the (renamed) update.zip and your ML2 will now be NE3 (Android 4.4.2).
At this point you have the official ATT i537 firmware and you can root with towelroot.com and make any other desired changes.

I537UCUBML2 (4.3) Released 2014-01-07 is the right ML2 to use? It is the 1.2GB Oden file. Sorry for such a simple question. I'm pretty new to this and don't want to use the wrong file and brick my phone.

Yes, that is the one for i537. The 1.2 gb download will contain 4 parts and you will need to find Odin (easy to find as there are many filehosts). Read the discussion threads to alleviate any concerns but it is simply a matter of opening the archive somewhere on your system, installing Odin and then just inside Odin open and point each of the 4 parts, reboot your phone to Downloading....mode (Vol Down, Power, Home) and connecting USB cable....

Thanks xdafly! I'm gonna download a couple of big files and do some reading till my eyes bleed!

I have an i537 running 4.4.2 (NE3) with the MF1 baseband (to be useable on AWS) and I still have the same issues with WiFi tethering (hotspot) that I had on ML2.
@xdafly your suggestion of 4.4.2, was that to help hotspot run while using non-ATT SIM cards? If so, am I missing a step? (I am currently not rooted, how does that help in this case?)

[Q] Solved Help - Baseband version - unknown

A little background. A few months ago I purchased a Samsung Galaxy S4 Active SG-I537 from a person on Craigslist after my HTC One M7's microphone died. Anyway, I thought the phone was fully stock. I started to become suspicious that this was not the case when I checked for software updates from AT&T and the updates began to fail repeatedly. I downloaded a root checker from the Google Play store and, confirming my suspicions, I had root access. I didn't really like finding this out this way, but it was my own fault for not asking. Having installed CyanogenMod on both a Galaxy S1 Fascinate and an S2 Skyrocket, I knew something about these things and decided to just live with it as the phone seemed to work otherwise.
Recently I tried playing video on my DirecTV app and found that the app would not function on a rooted phone. That coupled with the fact that I am hearing that Android 5.0 Lollipop will soon be released for the S4 Active made me want to return the phone to a stock firmware. So I began reading. The problem I have is that I have no idea whatsoever how the phone was rooted. I know that the firmware was 4.2.2 UCUAMF3. So I downloaded ODIN and the full ODIN package of UCUCNE3 and then followed the below guide to a T.
Everything seemed to work, I got a pass green light from ODIN. But I have a circle with a line thru it where the AT&T wording usually appears. The 'about device' page in the settings also says 'Baseband version' is unknown. and I have no cell abilities. I can do everything from the smartphone end via WiFi. But I have no cell phone capabilities. Can't make calls, etc. What I need now is someone to point in the proper direction of where to look for the knowledge on how to fix this problem. Any help would be greatly appreciated.
Thanks.

Download the NE3 Full Odin Package from the i537 Firmware Thread.
Extract SGH-I537UCUCNE3_v4.4.2_ATT_ALL.zip using a program such as 7-zip.
Download the Windows program Odin. For more information about what Odin is and where to get it, please read the Odin section in the first post.
Open the version of Odin that you downloaded (preferably Odin v3.07)
Once opened, you need to load the files for the Bootloader, PDA, Phone, and CSC. The required files are located in the Odin Files folder. It should look exactly like the screenshot below with the appropriate checkboxes checked.
Next put your phone in download mode. For more information on how to put your phone in download mode, please read the download mode section in the first post.
Once your phone is in Download Mode, connect it to your computer using the cable that came with your phone. IMPORTANT: Odin and Samsung phones are very finicky when flashing firmware, the only usb cable that is guaranteed to work is the cable that came with your phone. You may use other usb cables, but Odin may not detect your phone. If Odin does not detect your phone try connecting to a different usb port or a different computer.
If your phone has connected properly it should show up properly in the Odin window similar to the following picture:
Once Odin has detected your phone, hit Start. It will take a long time to flash the package to your phone and will completely wipe your phone. DO NOT DISCONNECT THE CABLE OR TURN OFF YOUR COMPUTER. If the process is abruptly interrupted you risk permanently bricking your phone, so be careful.
When the program has finished it is safe to disconnect everything and reboot your phone. Your phone will be completely stock, unrooted and you will have to setup your phone from scratch again. If you wish to root the NE3 firmware, please visit the towelroot website.

tried asking the person you bought it from?
I've heard that installing a firmware/rom twice in a row can help things. try that! good luck!

Wow, I spent 7 hours on this yesterday and couldn't find that thread. I guess my search skills aren't what I thought they were. A huge thanks, O-T. I'm back up and running. I flashed the MF1 modem to get the service menu back up and selected the correct option. I was then able to reflash the NE3 firmware and now I have baseband and IMEI properly identified and working. Took another couple of hours but I'm there. Again, mucho thanks.

ATT Note III SM-N900A not able to auto-update.

I've got three problems.
Won't over-the-air update
Computer can't recognize phone no matter what I do even when installing drivers separately, in "normal" mode, that is, with the phone booted and running.
Driver updates are useless
But Download mode works. So here's what I want to do. Knox is still factory-fresh and shows no alteration. I want to go back to completely stock rom in the hopes that over-the-air will then work as well as re-enabling computer to phone access (Mac/PC Kies).
Download mode works (99.99% sure). The phone works absolutely great, except for the three problems stated above. So can I do this? Here are the version numbers as found on the phone. I need help really bad here.

Since you can get into download mode I would just Odin flash the NC2 files http://forum.xda-developers.com/showpost.php?p=54803130&postcount=136 to return your phone to stock. BUT once you do and you do the OTA Update, you will be on stock Lollipop and it CAN NOT be rooted! ONLY way to root it, is flash the NC2 files and root it (Just a heads up). IF you don't want root and want Stock Lollipop then just flash these files with Odin [100% Stock] Lollipop 5.0 (N900AUCUEOC1) Odin Tars http://forum.xda-developers.com/note-3-att/general/100-stock-lollipop-5-0-n900aucueoc1-t3069609

Stock Att Galaxy S5 stuck on 4.4.2

Downgrade AT&T Samsung Galaxy S5 G900A from 5.0 to 4.4.2/4.4.4

Few days ago I bought the Samsung Galaxy S5 G900A unlocked. There was Android 5.0 preinstalled whith baseband vOC4! I tried to make the downgrade to 4.4.2 because of the root, and always gettin the brick. Saw the post about flasjing G900A_OC4_Stock_Partitions and it helped me a lot with unbricking! I tried all the ways of downgrades: recovery ZIP update (including OC4 firmware w/ OA1 bootloader) , ODIN flashing different stock roms, custom roms, kernels etc. Can I make a downgrade with that baseband? I've read somewhere that it's impossible to do in this case...
Really confused now after all this.

No need for confusion. There is no way known to humanity that will allow you to downgrade from 5.0 to anything else.

Im in the same situation let me know if anything changes im about to return mine and hopefully get one still on kitkat or get a tmobile version

ODIN back to OC4 to unbrick and remember; if you can't root you, can't do anything but wait for root or buy a different model phone.

ODIN back to OC4?
There is no way at this time to ODIN back to OC4, OA1, or whatever.
There is only a ".exe" file for OC4.

similar situation
Hello guys,
my situation is quite similar to the posters one. i've bought the S5 active (AT&T) with some custom TMS5 rom, when i boot i sie unlocked lock icon.
the version is 5.0: the kies is showing info like: G900FXXU1BOC7/G900AATT3BOC4/G870AUCU1BOC5/G900FXXU1BOC7 (ATT)
the question is can i get somehow to the STOCK firmware? maybe upgrading to the 5.1.1 will get rid of this "custom stuff"?
if so, what's the best way to do it?

I purchased a new G870A Galaxy S5 Active this week, which was preloaded with OC5 (5.0, Lollipop) firmware. I was able to root the device by downgrading to 4.4.2; the guide here was very helpful: http://www.droidviews.com/update-att-galaxy-s5-active-to-lollipop-root-it-and-enable-wifi-tethering/
The exact procedure I used:
1. Flash NE4 firmware with Odin (The latest heimdall from git didn't work; I had to boot Windows 7 and install Odin & Samsung USB drivers)
2. Reboot the phone in recovery (power+volume up+home). Use the options to clear cache & reset to factory default
3. Reboot the phone normally. It might appear bricked & take up to 5 minutes to get past the AT&T logo.
4. Root with Towelroot
5. Follow the instructions on the linked page to install pre-rooted OF3 (Lollipop) firmware and the OC5 bootloader.
6 (important). Kill OTA updates by renaming /etc/security/otacerts.zip & /system/priv-app/wssyncmldm and then rebooting. Delete anything in /data/fota for good measure. (Use your favorite root-enabled file explorer or shell.)
Note that this will not work if the phone has received OTA updates beyond OC5. See this thread: http://forum.xda-developers.com/att...w-to-update-to-g870aoc5-5-0-keeproot-t3083841
