[Q] Galaxy s5 Odin and flashing

after towel was released at&t released a update which fixed the patch that was used to root in towelroot. I have heard that there are alternative rooting methods which I have tried that involve Odin. For some reason though when I try to use Odin it always told me fail and after a certain amount of tries in bricked my phone which is now in a boot loop. can someone help get me out of that bootloop?
I also have another question. Can't you just flash a older version of android to your Galaxy s5 and then use towelroot to root it?
(I am very new to this rooting experience and I would appreciate step by step guide):laugh:
Than you
You probably had "fail" message because you hadn't disabled the option "Reactivation Lock" in Security settings before using Odin.
To fix your phone, just boot in Download Mode, then flash a working firmware for your S5. Do you how to do that ? Can help you if needed
I also have another question. Can't you just flash a older version of android to your Galaxy s5 and then use towelroot to root it?
Yes you can, but prefer using newer version for you'll have better performance and security updates.

[Q] Can't update, downgrade, or rest to stock OS, PLEASE HELP

Good afternoon all if anyone could please help I'd greatly appreciate it!
So I just bought a Sprint Galaxy S5 from ebay with the assumption that with some customizing I'd be able to get the phone domestically unlocked. I got the phone and it was already updated to 5.0 Lollipop so I followed this tutorial to get the SSU.apk to actually work
http://forum.xda-developers.com/spr...locking-sprint-galaxy-s5-g900p-t3085624/page2
After a lot of time I was successful at rooting the phone and was able to downgrade to 4.4.4 but the tutorial calls for 4.4.2 but it seems that 4.4.4 was the only fw that would successfully install.
But now here's the problem I was able to obtain the domestic unlock code through Sprint but now the activation/update app doesn't work and doesn't open automatically the way that the reps said it would,. I've tried to reset stock through Kies but Kies doesn't recognize the phone. I've also tried to use Odin through out this process not only to reset back to stock but also downgrade the fw and the modem. The really annoying part is that small PDA/AP updates and installs work fine but when I try to Odin the original tars it always fails 100% getting a "sw rev check fail aboot fused 2 binary 1 " error on my phone.
I really don't know what to do at this point, and it seems the error is associated with a soft brick but the device still powers on and boots.
I thought this would be a pretty straight forward process but I've hit the wall and am losing my mind, I need help!
P.s. I flashed 4.4.4 fw with CWM and the device is still rooted
Thanks

Root for Samsung Grand Prime SM-G530AZ Lollipop 5.1.1

Hello,
I have searched all of over the internet for my phones root with no success whatsoever.
- Kingroot does work on the phone but when I reboot my phone it looks up my bootloader and tells me that I have flashed an unauthorised rom and that I should contact cricket. I then had to flash the stock rom with kies.
- I have tried to flash all sorts of recoveries including TWRP and CWM recoveries. It just gives me a fail and on my phone it says "Secure Check Fail: Recovery".
Please help make a root for my phone.
Thank you in advance:fingers-crossed:

If I were you I would not update because there are no ways to root the phone, at least, I have not found anyway. And the update is through kies 3. But if kies does not give you the update then that is great for all of us on this form. http://teamcspire.com/index.php?/to...s-for-return-to-stock-tarmd5-for-use-in-odin/
Go to this website and please extract the software from kies 3 so that all of us can use it to downgrade from 5.1.1 to 4.4.4. if that's the situation. Please reply if you run into any trouble because I have already done this for the firmware 5.1.1. and I know how to do it.
Thanks in advance

The firmware that you are trying to flash is giving you the sw rev error because that firmware is an older/downgraded version than the version that is already on the phone. You have to flash the firmware that is the same as what is already on the device or a newer version, you can't flash an older version. Find the newest, most updated firmware that you can find for your specific model number.
Do a Google search for:
"Stock firmware for SM-G935FD"
Then find the newest available version that is made for your specific region/carrier.
