Samsung galaxy s5 at&t sm-G900a isn't rootable. - Galaxy S 5 Q&A, Help & Troubleshooting

Towel root doesn't work on the Samsung gs5 g900a. Root is blocked on this phone from at&t.

Same thing is happening to me. I had it rooted until the phone updated itself and now I can't root it through TowelRoot anymore. This sucks.

I'm sure it won't be long before one of the clever guys around here has it figured out.
I was towel rooted before the update.

Thats a known "problem"…
Towelroot used an old kernelbug for rooting, but since june/july Samsung use a newer kernel without this bug and towelroot cannot work anymore!
But following should work:
Update the Firmware and reboot! (Wait some time after reboot, to finishing the update on reboot!)
Then flash the old Kernel (ONLY the Kernel) and root with Towelroot. Ignore the Errors that comes from old (wrong) Kernel.
After rooting flash back the actual kernel…
… FINNISH

Mine is rooted, no problems doing it.

I'm new to android.
Never done a kernel change.
I'm going to read about it.
What I do know is I was rooted with towel root, the then it installed software updates from att. At this point I was no longer rooted and towelroot now says it is incompatible with this phone.

[Q] How do I flash a rom on my Verzon Galaxy S5

It's been a super long time since I flashed a Rom. I use to use Rom Manager and do back ups there. I rooted my Galaxy S5 on Verzon. My android version is 4.4.2 and my kernel version is 3.4.0 Mon Mar 31. G900V. The stupid update is forcing me to update but I keep scheduling it for later. What Roms are safe to flash without tripping knox?
Be sure to check http://forum.xda-developers.com/verizon-galaxy-s5/development most of the threads have installation instructions and should say if they trip Knox or not

Nothing forces to take an update and most rooted phones are probably better off to eschew updates. Any update is likely to break root unless you use something like Mobile Odin Pro or Super SU Pro that have features that try to retain or regain root for you after an update is installed.
You can accept an update OTA, but it's a lot better to install with Odin. Spend a few minutes perusing update threads (which you should have done before posting anyway) in the Verizon forum to get a better idea of whether the update is something beneficial to you or not.

[Q] Looking for Root for Lollipop

I have an AT&T Galaxy S4 SGH-I337. I was so excited about the update to lollipop that I un-rooted my phone and downloaded it as soon as I could. I am enjoying it, but I miss root access. Has anyone come up with a way gain root access with this new update? I know with the 4.4.4 update we could flash the old kernel and use towel root, any chance something like that would work for this version?
If this is being dealt with in another thread I apologize, I did look.
Try TowelRoot APK https://towelroot.com/

Please hit the thanks button if it worked
I'm interested in knowing how it turns out for you if you try towelroot. I got the lolipop update on my tab, and I'm liking it. However, I like having root so I haven't plunged in with my S4 yet, been doing some reading first.

Towle Root hasn't worked for the last few at&t updates. It's awesome but outdated.
Odin back to nb1, then root, then follow the instructions listed here.http://forum.xda-developers.com/gal...-to-update-to-i337oc3-5-0-1-keeproot-t3075814

What Custom Recovery to use w/ Lollipop 5.0.1 Rooted

I rooted my S4 ATT SGH-I337 yesterday with Kingroot while already having Lollipop 5.0.1. I then downloaded Flashify & Flashed ClockworkMod Recovery. Restarted my phone to goto recovery and I got a yellow triangle saying this phone has software unauthorized by att.
What Custom Recovery can I use and where can I find the latest version? Will TWRP work and also I've heard of something called Philz?
Oh and does bootloader have anything to do with this because when I rooted my S3 I never even knew or heard of bootloader.
Thanks in Advance

You will not be able to use a custom recovery because your bootloader is locked with no means of unlocking it or downgrading to an unlocked one. You have 2 tools that you can use, currently in lollipop. One is flashfire beta. If you ever purchased mobile Odin, you will be upgraded to the paid version for free. The other is safestrap. Safestrap isn't updated for lollipop but there is a workaround. Since you rooted with Kingroot, I'd suggest getting flashfire beta and then use it to flash the rooted 0C3 zip found in the OP of this thread :
http://forum.xda-developers.com/gal...-to-update-to-i337oc3-5-0-1-keeproot-t3075814
The reason is that Kingroot seems shady and installs other crapware. Also, if you try to update to 0C4, it will fail with the Kingroot rooted lollipop. It won't with Muniz' method. Well, at least I know it won't with the stock rooted one. I'm still unsure if the deodexed one will cause the update to fail.
Snapping along on stock rooted 0C4 I337, wishing for some good up to date lollipop ROM's to throw into flashfire
I have Flashfire Pro and SuperSU

My question is what is 0C3? and what is 0C4?
I have the paid version of Flashfire beta
The reason I want a custom recovery is so i can make a backup of my phone and then flash a rom preferably Cyanogen Mod if they have it yet. I hate this touchwiz. But I wanna make a backup like i was able to wish Clockwork mod. Is FlashFire capable of making a complete backup? I see the Backup option but have no clue which to choose and or what it is backing up??????

OC3 is the original Lollipop distribution for the AT&T I337. OC4 is the patch update which is assumed to have corrected the stagefright bug.
I don't have the phone, so I don't use flashfire, but I understand that you can do most everything with it that you can do with CWM or TWRP.
The bootloader is locked, and you will not be able to install a custom recovery. You will also not be able to install a custom kernel, so no AOSP based roms can be installed either. You're stuck with Touchwiz based roms. Period.
TWRP will work

No it won't. Only safestrap will work with the nc1 work around. Flashfire is great until you want to flash a rom with an aroma installer, then safestrap is the only option.
Can't upgrade to OC4
Hey, I have updated to Lollipop using Muniz's method back in April. You said that the udate should work with Muniz's installation. It is not working for me. Are you aware of this? I too have a locked bootloader, and am stuck with the Safestrap like many others.
Thanks,

Have you changed anything since the update? If you've unistalled or frozen any apps, or made any other change to the rom, the update will fail. It does work with the deodexed version of the rom also, that's what I updated with.

Can you root galaxy s5 for att smg 900a on lollipop version 5.0??

Please guys tell me there's a way to root the galaxy s5 for att smg 900a on lollipop version 5.0. If there's not should I upgrade to the latest firmware?
Thankd
You can't root g900a on Lollipop as of right now. AT&T locked the bootloader when they released 5.0 BUT.. you can downgrade your phone to KitKat. Then root it using Towelroot root and then flash a prerooted lollipop rom using flashfire Here is a link with a bunch of people that downgraded there g900a to KitKat and how they did it and worked around everything: http://forums.androidcentral.com/samsung-galaxy-s5/489071-tutorial-downgrade-samsung-galaxy-s5-5-0-4-4-kitkat-6.html This will help you out in starting the root process on your phone. You can also Google "Downgrade g900a KitKat".

This is not true. If you are running completely stock lollipop either becuase you purchased the phone with it on it, or you took the ota it is not possible to downgrade to KitKat, you will brick your phone. If you were rooted on KitKat, you can update to a prwrooted lollipop, which I am running now for example, and using that method allows you to downgrade as well with no issues so long as you don't take the ota. This only applies to the g900a.

Also not true.. You can downgrade your phone from 5.0 to KitKat DEPENDING on the version of bootloader. That will make or break the whole possibility of downgrading. Check the link I posted and read through the forum. It has been done by multiple people but the general consensus is if your phone's bootloader is past a certain version you're screwed for now and if you can't downgrade and root but you want to in the future I would suggest not updating for a while until there is a method of rooting your current version bootloader.

I did check the link you posted and only found people that tried it on a g900a unable to downgrade. There was no time that you could go from stock L to KK on the g900a.

To be quite honest dwade. You can save yourself a lot of headaches and stress by putting your phone on craigslist and getting yourself the g900f unlocked that way you can avoid all of these processes and the risk of bricking your phone lol If you're looking to root and get into modding your phone, AT&T & Verizon phones are the worst when it comes to locking things down.
Troubles rooting 900a with 4.4.4
I had problems using towelroot on a ATT branded 900a with 4.4.4. Any tips or links that can help me root to get rid of the Hotspot block?
Thanks in advance

It's certainly the case for the F variant that towelroot only works on 4.4.2 that was compiled before the end of June 2014......If there is a build that matches these conditions for the A variant, towelrooting may be possible.....If not, I guess you'll have to try CF Root or similar...
Edit.....check this thread......

Sm-t237p root?

I've been searching the forum for a few days now looking for a thread to help me. While I did find people asking the same I didn't find any useful help.
I had my tab rooted with kingroot for a long time but a few days ago I tried installing a recovery so I could flash xposed but something went wrong an it got stuck on the yellow sprint screen so I flashed a stock firmware with Odin to fix the issue. However now it won't root using kingroot. Am I doing something wrong? Does anybody have another idea of how I achieve root/recovery an xposed? It's been a while since I used the tablet so the only thing I can think of is I had it rooted before the 5.1.1 update, I honestly cannot remember. If that's the case does anybody have a downgraded firmware?
The tablet is a sm-t237p running 5.1.1
Update
Update - I was able to downgrade to 4.2.2 an active root thru king root. Now how can I achieve recovery? All the recovery posts are for different models.

Root for the SM-T237P on 4.2.2 is indeed achievable by Kingroot>then SuperSume>then Clear all cache with SystemCleanup.apk>Freeze all System Update Apps. In fact, I actually used an app called Root Cleaner. However, in 5.1.1 the SuperSume method does not work. I am searching the XDA world over for a copy of the PhilZ Recovery. Without it, we are doomed on such a nice tablet. There is no CF-Auto Root or TWRP for this model. And the Cf-330 method is garbage(No offense to those people using it). The SM-T237P updated yesterday to a more secure 5.1.1 dated June 26. Does anyone here know how to get a copy of the PhilZ recovery?

I actually just found somebody who posted a copy of it. It won't let me post links since I'm new but it's under galaxy tab 4 general called "Root for SM-T237P by sk8trix" it's on the last page. I have successfully flashed it an can confirm it's working. Now I'm working on xposed
