[Q]Recover root

I tried SuperSU root app and i realised that I don't like it. I pressed the button what said something like switch superuser or like that, after that I waited a little then my phone rebooted skipping LG logo.
After that I found out that original superuser application was gone and SuperSU didn't work anymore, then I installed superuser again and tried to update such it failed on granting root, tried again like 3 times and then it succeeded and superuser worked but after reboot it started force closing.
Does anyone how to fix it?
Thanks in advance!

hmm... I think you can root your phone again(the same way you did before ).Also, if you want to change from superuser to supersu(or vice-versa), the only thing you need to do is:instal the other app, open it, update binary and ONLY THEM UNINSTALL THE ONE YOU AREN'T USING.Sorry for my bad english, hope you get it

Yes, try to reroot, if it don't work, try to complete remove root and then reroot.If you have a recover, it's better to make a backup before, waiting for feedback, good luck

Is there either a superuser or super su app installed? There should be. Try going into whichever one you have and update binary, then rerun root checker and make sure you allow access when it asks for it

You only need one or the other, not both. Stick with whichever one came with the Rom. Go to the app and under settings choose update binary. If it asks for permission, grant it.
Delete whichever one you're not using.
And all custom ROMs on here are rooted

I've noticed with superuser I've sometimes needed to run the update a few times before it'll work.
If this has been a problem since you first flashed the ROM, I'd recommend doing a complete wipe of everything and reflashing the ROM

[Q] Unroot S3 without computer

Hi all. First off I'd like to apologise if this is in the incorrect place (as a seasoned user of forums like this I understand how irritating it can be) but I've hunted about and this is the most relevant board I can find.
The USB port on my GT-I9300 is broken - I can't charge and can't connect to my PC - so it's looking like I have to send it off to Samsung to get it fixed/replaced however I have rooted my phone. Is there a way I can unroot it without having to connect to a computer?
Any advice is greatly appreciated as I'm in a bit of a panic.
You should be able to pull a clean ROM onto it then reboot in recovery and do a factory reset then install the clean, stock ROM. I don't know if they will even care about that but a good just in case

Thanks for the response. Unfortunately I'm a bit of a luddite so I'm not entirely sure how I would go about doing the above?
There should be an option to unroot in the su app. Idk which su app you are using but super su has a full unroot option.

Thanks! I never noticed that option before. I'll give it a go.
I've seen some talk of needing Triangle Away & Mobile Odin to unroot my phone properly? Is that correct or am I okay just using the option on SuperSU since I've never actually installed a custom rom, I just unrooted the phone?
This is the Verizon forum. Not sure if the advice applies to the international version.

[HELP] Lost root

Greetings, I recently lost root on my Nexus 5 because I wanted to switch from supersu to superuser. I uninstall supersu from the app itself. I installed superuser and then tried to download the binaries, but it failed. But my bootloader is still unlocked and I have twrp as my custom recovery.

Did you actually uninstall the binaries from SuperSU?
What rom are you on?

As far as I am aware, SuperSU is the only choice.
I tried reinstalling supersu but it doesn't work another thing is that I believe supersu is being detected by some games as a hacking application, once I removed supersu my games started working again. Just wanted to fund out if it really was supersu
Sent from my Nexus 5 using XDA Free mobile app
If you removed the binaries, the only way to get SuperSU is to flash it.
And Is it possible for me to flash superuser? Or am I stuck with supersu? I have no problem with supersu I like it. It's just not compatible with a few games I have.
