I have a Samsung Galaxy S5 Active SGH-I537 on carrier AT&T and have tried to unlock unsuccessfully. I have a couple of months left on the warranty but want to use it on my carrier. I was thinking of rooting it and unlocking with regionlock away, but want to be sure if something goes wrong I can go back to the stock ROM. This assuming of course it doesn't get completely bricked and can send it to Samsung for whatever repair.
Can this be done without Samsung detecting it was rooted? If so what would be my best course of action?
I am on 4.3 with MF1 baseband.

Grab the stock FW from here and flash with ODIN.
I just now rooted the phone using the method from this page using SafeRoot and Disable Knox. I did have to flash the pwnedkernel Modem in CP using ODIN 3.09 from here. Now that I was rooted, I installed and ran RegionUnlock Away from here.
I finally flashed the modem using to originalkernel.tar.md5 in CP using ODIN and flashed.
I now have my SGH-I537 phone rooted and unlocked.
Using the method I mentioned above, if I ever want to UNROOT and leave no trace, what is the correct way to do so?
Would Flashing the stock firmware be enough?
Thanks.

Hi I recently flashed stock firmware but forgot to reset the flash counter. Just to be sure I wanted to ask if it is possible to root using Exynos Abuse, so that I can run Triangle Away and then unroot the phone again.

I can confirm the ExynosAbuse 1.40 rooted my I9305 with stock firmware successfully. Can't tell about TriangleAway, but AFAIK it should work after rooting.
Basically my phone was rooted under mj5 at&t gave me an update. Unrooted my phone and now I'm under build number Nb4 and want to reroot but now afraid the same program I used well trip Knox. Can I still root without tripping? (I used kingo)

I re-rooted with kingo after the update. Knox is still fine. Some users report that newer versions of kingo don't work. I used ver1.8 and it was flawless.
Not rooted or anything. I cant seem to receive any OTA from AT&T. Tried Samsung kies at it says my phone is on latest firmware, even though its only on kitkat 4.4.4
I found a solution by quick googling. I'm just wondering if this is advisable and wouldn't void my warranty.
http://www.droidviews.com/install-rooted-lollipop-on-att-galaxy-s5-sm-g900a/
Note: it does say install "rooted" lollipop on the link, but it was only optional. Seems pretty shady to me. I just don't want to flash anything unsafe that will mess up my device.
Is this reliable or is there another way? Not planning to root/void my warranty atm.

You could root and go to 5.0 and never use a root application. You could also unroot your phone using the app that prompts access to administer those privleges. Technically you would void your warranty but you can always downgrade back to Official 4.4.2 for any reason (sadly you can't root 4.4.4). Just a suggestion, my friend. ?

Hi everyone,
I have a stock Tmobile Galaxy S6 that I bought on release day and that I haven't touched since while waiting for the 40 days to elapse so that I can unlock it and use it on AT&T. Unforunately Tmobile screwed something up and it's been 2 months now and I still can't unlock it through the unlock application and I'm not receiving the emails their customer service is supposedly sending me.
The phone keeps nagging me for OTA updates, I haven't done any yet. If I do accept the ETA, does that close any doors or make rooting more difficult? My goal is to eventually flash the unified G92xF/I/T Galaxy S6 Universal Deodexed Mod edition ROM.
Thanks!
Maybe a little more difficult than 5.0.2, but you just gotta follow the correct steps. It will however, trip knox. Did you try searching for the email manually? I had that problem once and had to search manually because they didn't show up for some reason

I did search for the email and never received it. The tricky part is I had my friend bought it for me so all customer service calls go through him. I'm about to leave on vacation abroad and at this point I don't care if it's unlocked because I won't be roaming anyway, I just want the latest official fixes and enhancements without jeopardizing my ability to flash custom roms when I get back. The reason why I'm not flashing the custom ROM yet is because I think they get rid of the Tmobile unlock application which I'll need in the future when Tmobile gets their act together.
Sounds good! When you say it will trip Knox, are you saying that in regards of having to flash a custom recovery for the ROM I mentioned? If so whether I stay at 5.0.2 or update to the latest firmware wouldn't change that right?
If you are planning to flash a 5.1.1 rom then yes you will have to trip knox on 5.0.2 or 5.1.1 bootloader. Updating to full 5.1.1 firmware is recommended for this, otherwise fingerprint reader will not work. Now, there is a way to not trip knox on 5.1.1 but you will lose that fingerprint functionality. There is also a method to not trip on 5.0.2 and retain fingerprint functionality but you can only flash 5.0.2 Roms
I was just browsing the forum and came across a post that linked to a new way for unlocking the Tmobile S6 using Android SIM Unlocker. It looks very promising so I may actually be unlocked within the next 24 hours. So you recommend that no matter what I let the OTA update my phone to 5.1.1 before flashing anything in order to retain fingerprint reader functionality? I intend on running 5.1.1 and not staying on 5.0.2.
The ROM instructions say: "If you're experiencing ANY issue, then first make sure that you're on the latest bootloader/firmware (see post #4 for latest one for your model), and that you've done an clean install (data/factory reset before installing the ROM)."
Yes

Follow the same procedure for rooting and flashing 5.1.1 without tripping Knox but flash a 5.0.2 rom after you are done

Can I flash a rooted Galaxy S5 with OF3 baseband version to Tmobile stock ROM by using Odin? I keep hearing that ATT Galaxy S5 has a locked bootloader but how does that stop it from using Odin to flash my own modem and baseband. Is it not possible?
I found all the modem, baseband, and ROMs for Tmobile at this location.
http://forum.xda-developers.com/tmo.../compilation-s5-g900t-stock-firmware-t3042400
Update: bought the phone full price 1.5 years ago so does that mean I have a locked bootloader or can I install any custom ROM?

No you can not flash the T mobile bootloader. Odin can flash a bootloader if the bootloader is unlocked only. Yes your OF3 has a locked bootloader as this phone has always had it locked and no one has been able to unlock it. No you can not install any custom rom. If you want a T mobile rom you will most likely need to port it to your phone (no i don't know how) best to stick with AT&T roms if you don't know how to port.

@Rakuu i started to put it back on my phone but not sure if i wanna deal worth the trouble shooting of a lot of things again. Did you ever get it running smooth on the 900a? My 900t needs a new screen right so I've been running my 9p0a on TMS5 3.0.

I was running it for a while, but I switched to tms5 as well, can't remember exactly why but I think I was having issues with xposed. Couldn't live without the darkness theme though so I kinda 'ported it'(decompiled the systemui and stuff and used tms5 apks as base).

I've been running both TMS5 and Twi5ted for a while (Android 5.0). I've had on-going annoying issues with both. TMS5 freezes quite often, and Twi5ted will randomly reboot. Is there a way to install (Odin) a stock Rom (i.e. from here) and stay rooted, or flash one and re-root? If so, could I install the 5.1.1 version or stay on 5.0? I just realized as well that, with Twi5ted being based on TMobile, it shows my model number as G900T vs. the original G900A.
Thanks.
