Trying to Root phone using SuperSu - need help.

[tomx2x]

Hi.
This is my first post, I hope i'm in the correct forum.
I have a friend whom I requested to Root, Flash TWRP and Install LineagOS and GAAP on my OnePlus One phone.

He successfully flashed TWRP and installed LineagOS & GAAP but could not root my OnePlus One using SuperSu. He mentioned permission issue trying to root.
He went back to his country, so I am stuck trying to root my phone.

I would like to root my LineagOS (formally OnePlus One) using SuperSU.
I have downloaded/copied the latest SuperSu zip file into the Phone Sd/Download folder.
I went into custom recovery (TWRP).
Click on the Install button and verified I can see my SuperSu zip file.
Since this is my first time performing a phone root, I did not click SuperSu zip to install, until some experts can assist. me.

Just a few (Q's).
Questions:
a) Should I run any preliminary steps prior to clicking install SuperSu.zip?
b) Since I have LineagOS, GAAP apps already installed, will they be wiped after rooting SuperSu. If (Yes), any software available to backup/restore LineagOS & GAAP prior to the root process?
c) My friend mention “Permission problems with OPO”. Are there some options to open OPO and allow rooting SuperSu?

BTW: I do have the adb & fastboot installed if I need to enter some commands to get this done.

Thanks.
Tom.

I downloaded LOS extras from the link you provided.
Went into TWRP
Did the Install
Then rebooted.

Went back to phone\Developers Option
Root Access is still grayed out.

See screenshot attached.
Any suggestions?
Should I just do a TWRP factory reset and start over?

My last attempt.
Download this exact zip : https://www.androidfilehost.com/?fid=385035244224405790
Wipe System, data, cache & dalvik
Flash ROM - Gapps- SuperSU-v2.79-201612051815.zip
Reboot

Ok, I',m not sure, but I maybe rooted.
See attached screenshots.
My concern, in Developers Options, Root Access shows “ADB Root Only” see attachments.
Shouldn't I get a option for “All Root Access”?
Or does supersu have it's own internal options.
I did successfully launch Titanium backup(did not do backup) & Root Checker responded with root was successful. see attachment.

But Is there another verification i can do guaranteeing I'm am 100% rooted on the phone?

A Post by Sam Nakamura stated:
“Important, it's not a good idea to flash lineageOS su, then supersu, then magisk after each fails, at least restore your clean boot partition from twrp.

I was testing today the supersu zip for V2.79 for 2016 provided by psxda97.
Then about to install Magisk Manager when Sam's post gave me the idea to give this one more shot and full restore from my original backup.

Here's what I did:
1. Did a TWRP Full Restore from my 7/8 backup. First backup prior trying any supersu.zip install.
2. Deleted all prior supersu.zips from my PC.
3. Downloaded a fresh copy of supersu V2.82 suggested by psxda97 and Sam Nakamura.
4. Install the supersu.zip V2.82.
5. Rebooted.

The only other difference i have is the LOS (ROM) installation I used today.
My LOS install for 7/8 14.1 20170703-Nightly shows 2 options to select a root: (disabled or ADB Only).
The backup from Unofficial Sultan 14.1-20170625 has a slide bar to turn on/off ADB root.

Anyways, A Big Thanks to Psxda97, Sam Nakamura and Droidriven.

Set root access to "apps and adb"

@DRODriven:
I have only 2 root options 1. adb-only 2. disable. see screenshot below.
Since I can now launch Titanium Backup as a root application, would this not confirm I can exec root apps.

All custom ROMS I've ever used had the "apps and adb" option.

You're dealing with an android version and a device I'm not familiar with so I'm not sure how much help I'll be in this situation other than the general android knowledge of what "should" work. There are some specifics in your situation that I don't know about.

The other guy here have been more of a help to you than I have been, it's probably gonna be one of them that can help you get this straight.
