OS Upgrade with data reset (User data will be erased on upgrade)
This is the default OTA upgrade process.
OS Upgrade with data persistence
For users who prefer OS upgrade with data persistence please follow the process and steps documented here and here.

A/B (Seamless) OS Update implementation on SDM660 devices

Full OTA and Delta OTA (Patch) updates can occur while the system is running, without interrupting the user. This means users can continue to use their devices during an OTA upgrade. After the installation of OTA package is completed, device reboots into the updated image.
AB device are fault tolerant by providing a backup slot. If device fails to boot-up, then it will fall back to a backup slot (reboot back into the old partition) and the device remains usable.

Updates can be streamed to devices supported by this document, removing the need to download the complete package before installing it.

Starting with Android 11

Full OTA packages and Delta OTA packages of each LG release will be available on Zebra.com.

Delta OTA packages can be streamed and installed on the device.
AB updates can be streamed using LifeGuard Over the Air (OTA) 3.0 APIs.

OTA Delta packages available on Zebra.com will be sequential in nature.
For customers who are using Zebra LifeGuard Over the Air (OTA) solution, you can upgrade to the target OS LG software version in a single step with the help of a single OTA delta package. This OTA delta package is called true delta package which contains the exact delta required to install the target LG software version.

This true delta OTA package will be serviced by LifeGuard Over the Air (OTA) solution and will not be available on zebra.com. You can find more details on LifeGuard Over the Air (OTA) solution at Zebra TechDocs portal.
The size of OTA delta packages will be much smaller than Full OTA packages.

How AB system is different to Non-AB system

Emo Atoa OTA Package	Faiga Fa'aleleia	Android AB Faiga	AB: Device shall apply Full OTA Package via Android AB mode when applied via EMM. User can manually enter recovery mode to apply Full OTA package too. Non-AB: Device shall boot into recovery mode to apply any OTA package.

Taimi fa'aletonu masini mo le Fa'afouina o le OS	–	+	AB: Full and Delta OTA updates can occur while the system is running, without interrupting the user. At the end, device reboots into the new installed image. Rebooting to new OS image is the only device downtime user will experience. Non-AB: Device reboots to recovery mode to install reset or special packages only. User cannot use the device while installing OTA package.
Fa'apalepale masei	–	+	AB device are fault tolerant by providing a backup slot. If device fails to boot-up, then it will fall back to backup slot (reboot back into the old partition). Non-AB: If device fails to bootup, then device is bricked.

OTA packages downloaded from zebra.com can be streamed to device, this requires customers to set up their AB streaming server and host the OTA package downloaded from zebra.com
Reset Packages or Special Packages	Y	N	LifeGuard Over the Air (OTA) 3.0 APIs do not support flashing of Reset or Special packages. Zebra.com customers can download, and flash Reset packages or any special packages available to them.

Sequential nature of Delta OTA packages

Ina ia fa'afou mai le Patch 1 (U01) i le Patch 5 (U05), e tatau i se tasi ona fa'aoga uma fo'i pusa delta vaeluaga (ie, U01, U02, U03, U04 ma U05) i le faasologa lava e tasi.

Android AB Mode for OS Update

Full and delta OTA packages will be installed via Android AB mode. As part of this:

Full and delta OTA package will be applied on the device silently in the background.
User can continue using the device while OTA packages will be applied.

Post installation is complete, a device notification will be displayed confirming the installation is completed and device shall auto-reboot after 15 secs.
Device will auto-reboot to boot into newly installed OS image after the OTA package installation is completed successfully.

Customers can also configure the device to wait for Update clients (e.g., FOTA) or EMMs to notify device to reboot.
AB streaming mode will be used by default for customers using LifeGuard Over the Air (OTA) solution to update the device. The OTA package will not be completely downloaded and saved on device before starting the installation. Rather the OTA package contents will be streamed to the device and installed.

StageNow tool can be used to perform OS Update using an OTA package in manual mode (without the need to go into Recovery mode). Please search and click on Power Manager section in the link provided.

OTA package consists of following

HLOS images (system, vendor, boot and dtbo)
Non-HLOS images (QCOM images)

Recovery Mode for OS Update
Reset packages and any special packages to update Zebra Device Management partitions will be installed via recovery mode.

As part of this:

The device will be automatically reboot to recovery mode.
Reset packages or special packages will be applied using recovery mode.
Device will reboot back to home screen after installation is completed in recovery mode.
Customers can enter recovery mode using key combinations or using “adb reboot recovery” command.

User Notification for Full OTA package Upgrade or Downgrade

SPR 36526 was fixed in 01-18-02.00-OG-U00-STD/01-18-02.00-ON-U00-STD OS version. With this fix, we now bring user notification when a Full OTA package is being installed. Earlier OS versions had implemented a silent OS update and thus user was unaware of the background OS Update process.
Few of the features of this user notification:
1. This is applicable for Full OTA package and OTA Patch image.
2. On start of Full and Diff OTA package installation, an Icon (android system icon) will be displayed on the Status Bar.
3. On pulling down the notification drawer, a notification will be displayed informing that OS Update is in progress and device will Reboot automatically on completing the same.
4. User will have no control over this notification. i.e., User CANNOT
  - Pause/Snooze the OS Update request
  - Cancel OS Update request
  - Prevent Reboot of device
5. Notification can be cleared by User. Once notification is removed, no new notification shall be displayed again.
6. If EMMs have selected “Suppress Reboot” option while installing a Full OTA package, then device will not auto-reboot. User Notification too indicates the same and waits for EMMs to reboot the device.
7. The notification will also display system interrupts blocking OS Update process. E.g., Low Battery, Media Eject etc.

In prior desserts, if the device was flashed with an OS dessert or version that is not supported by the device a notification used inform user that a sub-optimal version of OS is running.

Meafaigaluega uma
This notification is removed from Android 11 onwards.
