[Q] root for JDQ39.19505XXUBMEA

My new Samsung Galaxy S4 GT-19505 is running build JDQ39.19505XXUBMEA (android 4.2.2).
I haven't found anything on this build number with regards to rooting, so I'm wanting to be a little cautious before I attempt anything.
Any pointers on what tools / options I might attempt to use to root this?

Flash CF-Root with Odin and you`re rooted. Link http://forum.xda-developers.com/showthread.php?t=2219803, read the OP well and it will be easy.

Thanks for your quick reply!
If I'm reading things properly, that will root my device & reset it to factory defaults (ie: wipe it). Correct?

No, it will only root it, you will not loose any data. After that flash a custom recovery if you need it and Busybox from Google Play,

There won't be any changes but root will be extra it won't wipe anything and u need not factory reset also
.

I tried it, and I'm not sure if it worked or not.
I have a a new SuperSU icon, but when I open it SuperSU tells me that the binary needs updating.
When I try to update it though it comes up with "Installation failed!"
Did the root fail? Is there something wrong with SuperSU? I'm not sure what's going on :s

Close all apps, reboot and try again to update the binaries. Have you checked for an update of the SU app in Google Play?

There was an update, which I have installed.
I also just installed Root Checker (https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck&hl=en) which tells me I am not rooted

Open the SU app and unroot and try rooting again by flashing CF-Root. Do you have usb debugging enabled on the phone in developer options?

I have debugging enabled.
I tried re-rooting, and now have no SU app at all
Very confused. This should be a simple process.

[Q] Accepting OTA after towelroot

Hi,
Rooted my phone in hopes of installing neatrom with mobile odin pro, but for some other reason mobile odin pro just crashes when trying to start it.
Now I'm considering to reset to factory settings, and before doing that install the ANG2 update just to check it out.
Will i get problems besides that my phone ain't rooted anymore when installing the OTA? or in the other case, will i screw something up with a factory reset?

Towelroot will not work (yet) on NG2 mate. If you are allready rooted install superSU and superSU Pro from Play and enable Root survival to keep root after the OTA. After you installed superSU + Pro reboot and enable root survival and accept the OTA.

Hi,
Thanks for the reply. Okay so thats safe.
What about doing a hardreset on the phone, that will unroot it and set it completly back to stock right ? I just want to see if i can get Mobile Odin to run on the device then, since i have no idea of why it refuses to start as of now.
Hardreset , then run towelroot again after the hardreset.. Will that work or will i brick it?

Did you place the rom md5 file on the external sdcard and did you grant Mobile Odin superuser permissions and enabled usb debugging?

The only thing that happends when i try to launch M. Odin is a blue popup stating that Odin has crashed, so it dosn't come that faar. However just managed to find a thread stating that MOP has trouble with ART, so going back to dalvik on the phone now to see if that might be the problem *crossing fingers*

Have you installed BusyBox from Play? MOP needs that to work.

Help to unroot my S4 LTE

Hey, i need help to unroot my S4.
I have rooted my phone with odin and a CF-Auto-Root file. Now i want to unroot my phone but i dont want delete my data. I have tried to unroot with Supersu (full unroot) but it doesnt works so good. I want to look for Software Updates and it says my phone is modified. So can anyone help me ?
I have a Samsung Galaxy S4 LTE GT-I9506
(Sorry for my englisch, i'm from Germany )

You need to root again. After that, use triangle away to reset flash counter, binary status and system status. After this use the full unroot option in supersu. Never tried it like this, but it should work. I alway flashed the stock firmware after using triangle away and then factory reset.
Triangle Away can be found on the Play Store.
Support thread for Triangle away is here. You should read the second post, as it may help you.

Just download the same firmware u have from Odin and flash... That's what I did... Works great.

Another option is to use triangle away and then flash the stock firmware without factory reset, as pointed above, but I recommend the factory reset afterwards, as you may see some weird behavior.

[q] should not have rooted help please

So recently I rooted my S4 with Kingo and went fine. After a few weeks, I decided to uproot to get the Lollipop OTA. Unrooted through SuperSU app then factory reset. Finished OTA download with no issueand then it failed after two attempts, saying error and I should try using Kies.
That's strange I thought. Then after looking through the phone again, I discovered GSam Root companion is now a system app that can't be uninstalled. Other than re rooting and re uprooting or flashing stock firmware, is there another option. My computer is currently under repair for a broken LCD, so any fix that doesn't need that would help. Thanks!

Is your phone working or isn't it working? I can't figure it out based on your posts.

It is working just with an annoying "system" app and can't upgrade. May have over exaggerated a bit...

I then assume that you still run an old version of kitkat (because of the kingo root).
Why not reroot and delete the file? I think you can still use Towelroot because I think you are on an old version. That's an app that you need to install.
Do you have a custom recovery? And did you factory reset before trying to update ota?

Can't use towelroot and don't have a custom recovery. I'll re root once I get the update on Kies(borrowed a friend's laptop) , which currently isn't available yet.

What i don't understand is why you are so stuck on getting this OTA update... just borrow your friends laptop, and flash the Lollipop that you want through ODIN. Then factory reset, DONE...

Took it to Samsung and let them do that for me. Didn't lose any data either, and GSam Root let me Uninstall it afterward, which was something I didn't expect. Anyway, thanks for the effort guys!
