Non A/B devices

About

Non-A/B devices do not have different slots for it’s bootloader stack.

Requirements

1. a recent recovery image (see Recovery Images for options)
2. a PC to load AXP.OS in recovery (OTA is supported once installed)
3. an unlocked bootloader (not part of this guide! use www.google.com to find instructions)

New to AXP.OS

running incompatible vendor firmware (or if unknown)

If you are not sure whether the current firmware matches the AXP.OS build you want to install:

1. create a FULL backup of all your data, pictures, etc and and save them somewhere other than on the phone (all data needs to be wiped)
2. flash latest device firmware as described in the device’s install section
3. boot into recovery (e.g. by adb reboot recovery)
4. flash AXP.OS (e.g. with adb sideload AXP.OS.zip)
   • note: some devices report something similar to: (~94%) adb: failed to read command: No error, which can be safely ignored
5. ensure you factory reset (all your data will be erased!):
   • choose Factory reset
   • choose Format data/factory reset
6. boot into system / AXP.OS

running compatible vendor firmware
