Help !
.
I am now running the January patch version. . I have the latest root and TWRP and ElementalX kernel.
.
When I tried doing this a month ago, I ended up using ADB and the batch with 'w' and the monster large update.
.
With TWRP, I went looking on the phone's memory for the small 98M ota.zip and no joy. I hope I now do not need ADB . . .

You need to download full ota zip from Google. You can flash it with TWRP. Just remember to flash TWRP again after the ota zip, if you want to keep it. I did it when the ota zip were available. Try it at your own risk.

Have you flashed the OTA via TWRP for the past updates as well? I didn't realize we could flash that way

I thought the same that you could only sideload an ota update with a computer, but I confirmed by doing it myself that you can either download the ota update to your phone or add it to your phone from a pc and place the zip file in downloads then go to Twrp recovery and select install and flash the ota zip then do not reboot and hit home page and go back to install and flash the Twrp zip again to replace the stock recovery that the ota update flashed. You can also do this with custom roms to flash the ota update you just have additional steps but you can do all this and not lose your user data.

Here is what I did to update my Pure Nexus custom rom.

First off go to recovery and select reboot just to see if you are on partition A or B, then you have to I believe, sideload the ota update ( do not reboot system ) then go back to home screen and install then flash your Twrp zip again, then reboot recovery and install the PN zip, then flash the Twrp zip again then reboot Twrp recovery again and once again see which partition you are on, if your on the opposite partition which flashing the ota is suppose to flash to the opposite partition also flashing PN switches your partition. So basically I did all this then booted and needed to flash the vendor so I went back to Twrp recovery and flashed the vendor image then I switched partitions and did this all again.

I did this on both A & B so I have PN on both partitions and both updated for Feb security update. Now I believe your settings will still show as the Jan 5th update until Beans updates his rom to add the Feb security update, so you may want to wait or you can just dirty flash the PN update when it comes out.

Yeah its confusing lol.

Just for clarity can I update this way while on Pure Nexus? Do I wipe first if I can do this?
Read my post right above yours I updated Tuesday night while on Pure Nexus and I"am updated and on Pure Nexus and my data was not wiped.

If you want to wipe data you can just flash a full factory image and that will wipe data and start you out factory fresh with the Feb security update included.

Thank you.
Additional question : After the phone pulled down the small update, and I went into TWRP and look "all" over for that file name and came away empty handed. . I then booted back up and went into "Solid Explorer" and did a search and it ( also ) could not find any OTA or UPDATE on the phone. . wtf . . . .
.
So, when I get off work tonight, I'll pull down the 1.9 Giga Byte file and try that.
.
I know in TWRP there is a "sideload' in the advanced area. I do "not" need to use that one, correct. . I just need to use the plain old 'install' zip . . . .
.
A month ago with the ADB and the modified batch file, I was able to keep "all" my junk / apps and their setup . . . .
With this TWRP doing the monster file, is the data seg going to remain intact ?

You should be fine, just use the latest TWRP to flash the full ota zip. If you want to keep your TWRP, flashed after the ota. You shouldn't have any issues keeping all data.

Just figured I would mention, if you flash the 1.9 gb full factory image it will wipe your data unless you modify the image to remove the wipe part which others have listed on xda posts how to do that, my advice is to use the ota update download that to your phone or copy to your phone and install it from Twrp through install then after updating do not reboot system but go back to Twrp home page and install again and once again reflash the Twrp recovery zip as the ota update will flash back the stock recovery just as a full factory image does.

Just thought I would mention as if you did what you listed you were going to do you would have wiped all your data when you did not want to.

well I went off into google and doing the looking ( and more looking ) so you would not call me a lazy $hit . . . . and I got nothing .
.
Is this where you use ' 7zip ' to edit the internal ( text ) file in place with the 7zip, and it does the ( really spiffy thing of ) maintaining the integrity of the package ? ? ?
thx

Just to let you know I flashed Feb ota with TWRP. No problems at all. I flashed OTA and TWRP rc1 at the same time. Booted into system, then back to recovery, then flashed su. Just letting you all know, worked just fine.

Edit. Yes full OTA from the Google site. Not factory image, and not the one sent to your phone

Okay @old_fart I see people confusing incremental OTA's with Full OTA's in this thread. Having TWRP makes you unable to take the small (98mb) OTA without using a tool to assist like FlashFire (but that can be risky/experimental, and what's a 2 gb download to ensure your data stays safe?), but you CAN flash a full OTA image.

Here are clear instructions:

Download the OTA for your model/intended version here: https://developers.google.com/android/ota

Reboot to TWRP, then flash it. User-Data will remain intact. If you want to keep TWRP/Root, flash either or before rebooting to System. Otherwise, reboot away and enjoy.
