Root , custom kernel - Nexus 5 Q&A, Help & Troubleshooting

Hey there!
I did a clean install of the NitrogenOS. Now that im finished, I noticed that my phone probably isnt rooted, as I cannot give root permission to an app.
If I remember correctly ( its been a long time) I had to flash a custom kernel first in order to root my phone or something... Can I still do a dirty flash or a custom kernel + superSU over completely installed ROM ?
Thanks!

I'm am not familiar with the ROM but did you check under developer settings to grant root access?

Doesnt seem to have such an option.
Just tried to flash newest superSU over it, but nothing changes.
Just noticed that the ROM was supposed to have root pre installed , If I understood it correctly.. But root checker tells me it still isnt rooted.

Did you enable developer settings?

Go to Settings>About Phone> Tap on Build Number 7 times to enable Developer Options.
Go back in Settings. Tap Developer options. Search for "Enable Root Access" toggle and switch it on.

[Q] A way to root but stay stock so can keep getting OTA s?

(noob) Question: Is there a way to root my OnePlus and keep stock recovery (for now at least) so I can just get the OTA updates? I want to have root so I can use Xposed and LMT but still stay stock. Thanks

yep, just install the drivers, unlock the bootloader, install a recovery (i used twrp), then flash supersu. go over to the android development folder and there are toolkits there. im running stock rooted right now.
you dont have to unlock the bootloader or flash a recovery to root. just run "fastboot boot recovery.img" itll boot the alternative recovery, and you can flash the super user zip from there. it will only boot twrp or cwm but not flash it to the device and will not replace the stock recovery.
unlocking the bootloader just allows you to write to the boot partition and boot different recoveries and kernels from the device. it does set off a tamper flag which could void your warranty. but unlocking is not required for modifying the system partition which is what you are doing when you root.

You can install OTA updates even with a TWRP installed. You just have to untick the CM Recory option from Settings -> Developer Settings -> CM Recovery
What that does it tells the OTA update not to update your recovery when the option is unticked. If you leave the tick on, then every OTA will relock your bootloader and install CM recovery.
But all in all, OTAs work fine with root + twrp

That won't let you keep root, though it's easy to flash SuperSU from TWRP after every OTA.
A solution to OP's problem could be SuperSU Pro which lets you keep root even after OTA updates. I haven't tested it yet but the option is there.

Nevermind, I found the solution. I had to disable a Option in SuperSU settings because the CM comes not rooted from out of the box

im not sure people have really tried. youre welcome to give it a shot as it says its possibly compatible with everything. but theres already a root method that doesnt require bootloader unlocking and installs supersu which is most peoples favorite root manager.
Towelroot is incredibly simple I get a little nervous otherwise.. Is there a tutorial on the easy alternative, I only want titanium backup to restore my apps from s4 (considering I can do that)

Where is the option to "keep root after OTA" in SU?
I managed to boot the twrp recovery on 4.4.2..but updated to 4.4.4 33R and now it says SU binaries not installed...also cant boot recovery on fastboot as it says need to unlock the bootloader?
Why did update prevent this now?

Did you untick the option to update CM recovery during your update?
I didnt untick it no, but i never flashed the custom recovery in the first place as i just booted it up from fastboot on 25R, on 33R however its been disabled and requires unlocked bootloader.

@inffy,
Hi,
I unlocked bootloader before installing 22R and updated 25, 30, 33 & 38R with OTA from 'System updates' menu. After 38R i flashed TWRP recovery and rooted my phone without unlocking the phone again & its working fine. Perhaps, the we don't need to unlock bootloader again once it unlocked. Can anyone confirm it??

Root LG G3 D850 (AT&T)

I rooted my phone, then installed CM12 Lollipop ROM. Now my phone is no longer rooted. I thought that after installing a ROM the phone remained rooted. Now I can't root my phone, the adb command doen't work to root it again, also tried the TowelRoot method, but it doesn't work. Any suggestions? I want to root it so I can reboot into recovery and install other ROMS or backup my current ROM (using TWR manager or Clockwork MOD ROM manager) and run other tools.
If you installed CM12, then you have root and recovery. I'm not sure what you did wrong or what you've missed, but it's all there. Did you go in Developer Settings and make sure that root access is enabled. Also, you need to have SuperSU installed as well. Good luck.

Adb reboot recovery doesn't require root. So that's an option. Also cm supports advanced reboot into recovery when you enable it in developer options.
Off topic. How well does cm12 run on this device? Thinking about putting it on my d850.
Never mind. Don't worry about my question. I'll look through the thread and see what I can find about what's broken.

CM12 is pre-rooted, you don't necessarily need to flash SuperSU. Go to Developer Options and make sure at least apps are selected in the "root access" option.

How to enable In-Built root in COS 12.1

Hi,
Does anyone know how to enable in-built root in COS 12.1 ?
I can very well flash supersu, but what I have seen, flashing supersu also enables the "Root access" in Developer Options as well.
Is there a way to enable it directly from adb without having to flash supersu? I'm just trying to test the ROM with everything as stock as possible, and without root access, life is very tough.
Well you can flash the debuggable boot.img found somewhere in the firmwares thread, that will show the enable root option in development settings, but in my experience, it still wont work unless you flash superSU. Maybe someone knows more.
There is no built-in root in COS 12.1.
Cheers !! Thanks ..

CM13 Root enabled, but not working

Didn't realized and tried to install SuperSU on CM13. Got a bootloop which I fixed with unSU.zip (http://forum.xda-developers.com/showpost.php?p=63615067&postcount=2459). Now I have no root even though root is enabled in developer options. Any suggestions?
Me too, just encountered this problem
Edit: Dirty flashed ROM from update, seems to be working now.

Wht did you flashed supersu when root was already available in developer options? :/
CM13 already have su binaries and to enable them you have to go in developer options -> root. If you flashed Sultan CM13 (which i really recommend) you have to install SU from here. Remember to keep the TWRP updated.
EDIT: i read again the first post. I guess unSU removes all the binaries, the ones from CM as well. Flash again the same ROM and gapps without wiping data and you should be good to go
