Of course you lost root. That's normal. Just re-root. How did you root before?

I'm a bit surprised that installing the app from the market fixed it..... maybe I am missing something... LOL

hell guys, why be snobs?
ive been around here for many years, had many, many devices, probably a hundred roms, and I use the toolkit because I find it easier...and have had no major problems.
so
After rooting with the toolkit, SuperSU was not showing up as an app. Installing it via play store worked for me too... - it asked if I wanted to update binaries, I chose normal instead of via twrp, and after doing that and a reboot, all is good...
cheers
Mark.

If you accepted an OTA you will have to re-root manually or with the tool kit you originally used.
You can't simply install SuperSU from the Play Store and regain root. Sure the app will install (anyone can do this) but the binaries will be absent (i.e. no root).
You can test this by opening SuperSU. When you open it, it will tell you if it's working correctly.

[solved] root lost after ota gingerbread 2.3.6
i did it, the fault was in recovery, during OTA i lost the recovery CWM recovery and needed to re install it...thats why i cant flash the superuser app... now everything is ok fine and great! cheers!

What is eu.chainfire.supersu.MainActivity Emblem?

This process is important? I was deleting SuperSU and in says that if I delete SuperSU I will delete this file too...
If you're unrooting, you don't need to keep it.
Ok, thanks.
There is a way to see if there is any modifications to the system's file?

There's an OTA checker flashable zip in general I think.
No, not in the ota, I say in general, if I want just to control of there is any modifications without flash anything

There is only one way. By flash the OTA checker zip in custom recovery. It can be found in the general forum I believe.

Ok, so I have to flash this with flashify (rooted with towelroot)
After the flash I'll have to unroot the phone and just install Lollipop with the ota?

I think the best bet for you is to read the thread about root / update in my signature. OTA is proving too troublesome. I can't hand hold you through the whole process.

I already told you.
Ok, I've read your thread about how to upgrade to Lollipop the Nexus.
The fact is that my main pc have no working USB ports, so if I want to unlock the bootloader and stuff like this I have to use my second pc, and it is very slow (the last time to just fastboot a factory image it tooks me one hour of suffering).
I think that the method 2b is the one that is closest to my situation:
1. Unlock bootloader if necessary (This wipes data)
2. Accept OTA update
3. Fastboot flash a custom recovery image (of your choice)
4. Fastboot flash a custom boot.img (@Chainfire for basic root, @sykopompos for full permissive mode)
5. Flash from recovery, SuperSU
Click to expand...
Click to collapse
I don't want root, so:
2. Accept OTA update

If I have understood, the only thing that I have to do is use flashify to flash the OTA checker zip. file and than proceed with the OTA, right?
If there is another way to do this without use the PC, it will be great, but I don't know.
Is what I said right or I forgot something?
Thank you with your help anyway!

This is what you mean?
If yes, I can't flash with a custom recovery because I have the stock recovery (because I'm rooted with only Towelroot, so stock recovery and locked bootloader)

Then you can't use it! Wait for the OTA and install it.
I already have the OTA, but I think that there could be some issues, this is why I want to check if everything it's good, I don't want to brick/bootloop the device

You wont brick it. If you're not stock, it wont install.

[Q] superSu help

Whenever superSu asks for permission to run a root app my screen becomes unresponsive. Timer runs out and i am not able to apply grant permission. Help. This didnt use to happen when i was earlier rooted with towelroot. Right now also i ised towelroot
Have you tried re-flashing the supersu zip?

Yes. Didnt work.
Btw by reflash the zip file you mean reinstall it from pkay store, right?
Pardon the ignorance. Just found out that flashing a zip file and installing apps from play store are 2 different things.
Well my bootloader is locked and neither do i have a custom recovery installed. So flashing doesnt seem to be an option right now.. If i am not missing anything.
Are you running 5.0? If so how the heck did you root with towelroot? AFAIK you can not root 5.0 that way. Maybe that is a problem.

You need to flash the supersu zip using fastboot:
teamandroid. com/2014/06/19/root-nexus-5-android-444-ktu84p-kitkat/2/ (you're going to have to fix that link because I have under 10 posts so the forum won't let me post..)
Additionally you need to have an unlocked bootloader

To get root again either flash the latest CF Auto Root in fastboot or flash the latest superSU.zip in recovery or flash a pre-rooted custom rom in a custom recovery.

Root 5.0.1?

Hi I was going to use chainfires method but the best the web page it only sates 5.0 with the build number LRX210- which is different to 5.0.1?
Is there any way to root then?

of course there is a way to root 5.0.1.
use fastboot to either flash a custom recovery (TWRP is probably your best bet), or use fastboot to just boot into the custom recovery without flashing. Either way, once your in recovery, flash SuperSU (download here http://download.chainfire.eu/641/SuperSU/UPDATE-SuperSU-v2.40.zip)
done and done.

You sir are very wrong, you cannot flash that zip in recovery because it no longer works with lollipop... (Sigh)

actually, it does work. with 5.0.1, I'm rooted. Except when I flashed 5.0.1, SuperSU v2.40 hadn't yet been released, so I rooted with SuperSU v2.37, and then updated via the playstore when 2.40 came out. but it definitely works with Lollipop.
p.s. you need to have an unlocked bootloader to install a custom recovery (which is what I suggested doing). So in fact, my suggestion is completely valid and 100% relevant. In fact, I had assumed that you already had an unlocked bootloader when I posted.

Your point is again invalid and 100% incorrect- I have just tried and it has not given Me root. I have to manually re-root not flash the zip. See attachment

yes, and the way to "manually re-root" is to flash the ZIP in a custom recovery. You the app installed, but not the SU binary. So flash it in TWRP.

CF Auto Root and flashing the superSU2.40.zip in recovery both root android 5(0.1/0.2). Did it myself and confirming root access.
You can root with the same chainfires files for 5.0, and then you can update supersu and twrp

Crazy. Done it to me a few times. I even decided not to help him ever again some time ago, then took pity on him yesterday or the day before and the he did it AGAIN!
He's just a school kid, but you'd hope he would learn from his attitude, but apparently not.
What's worse, is he isn't even picking up the knowledge that people give him or reading the stickies. He's been Here pretty much a year in the n5 forum and cannot even be bothered to.understand the basics. Asks the most basic questions every time.

[Q] Lost Root on my nexus 5

Hi. After flashing my N5 from android 5.0.1 to 5.1 i lost root on my phone. Ive tried flashing the SU apk in recovery mode but it doesnt work. Bootloader is still unlocked and i had been using franco kernal, before i lost root access. Any ideas how i could get root back?
More info needed. What do you mean it didnt work? Did you relash twrp after you updated? That might be your problem right there.
