DISCLAIMER:

I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed.
YOU are choosing to make these modifications,
and if you point the finger at me for messing up your device, I will laugh at you.
and I am also not responsible for anything happens as a result of flashing these files.

Finally someone captured the Oreo OTA and I'm gonna show you how you can install it and be on Oreo 8.1.0 July Security Patch.

First, you need to be on stock NPPS25.137-93-2-5 , fully untouched, no root, no custom recovery, etc.
Warning: for some reason, at least for me, IMEI/signal were gone after installing Nougat through fastboot, but it was back after updating to Oreo, do this at your own risk.
If you are not, then you can download it from here and flash through ADB with this commands:

Code:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img

Now, what you need is Oreo OTA, download it from here.

OREO OTA

Now, how do I install this?

Method 1 - ADB Sideload
  1. Boot your phone to recovery mode by powering it off, then press power + volume down until you go to bootloader, now go down with volume down to recovery and enter with power. Now you will see a message "no commands", maintain power button pressed and then press volume up button, if you entered to recovery now you are ready.
  2. Connect your phone to your PC
  3. Select "Apply update from ADB"
  4. On your PC run
adb sideload <path to ZIP file>


Method 2 - SD card
  1. Put the ZIP on your phone's SD card while it is in Android
  2. Boot your phone to recovery mode by powering it off, then press power + volume down until you go to bootloader, now go down with volume down to recovery and enter with power. Now you will see a message "no commands", maintain power button pressed and then press volume up button, if you entered to recovery now you are ready.
  3. Select "Apply update from SD card"
  4. Navigate to where you put the ZIP and select it

Update takes some time, for me was like 30 min, be patient.

Huge thanks to:

@alanmax_tech for uploading the Oreo 8.1 OTA!
If I miss someone please let me know.

No - never Flash a stock ota in a custom recovery
You need stock firmware totally unmodified as explained in first post - if you don't have nougat stock rom firmware then flash it

Then flash ota via adb sideload or stock recovery (select recovery from bootloader mode then on the android screen hold Vol up & press power button)
