VERY IMPORTANT!
Confirmed on multiple phones......
The October 26th 2018 Oreo release to the Z2 Play CAN/WILL Cause a boot loop if you have a Verizon Phone and you update the Security and Privacy App.
IF.... you get stuck in a boot loop on your Z2 after updating to oreo or updating your Security and Privacy app you unfortunately have to factory reset your phone, then disable/force quit the security and privacy app that defaultly is installed on the Verizon phone.
To factory reset:
- Press and hold the power and volume down button at the same time to enter the boot loader.
- Select Recovery Mode
- You'll then get the android symbol with "no command" on the screen.
- Hold down the power button and tap the volume up button to get to the android recovery screen.
- On that screen select "wipe data/factory reset".
- Be sure to select "userdata + personalized content" to start fresh.
- After the wipe, select "Reboot system now".
Now that you're starting fresh go through your normal Google Login to get to the main screen.
VERY IMPORTANT... On all Verizon phones the Security and Privacy app comes installed and turned on by default. DO NOT UPDATE IT, or you'll run into the same boot loop issue after a restart/power cycle.
Be sure to disable/force quit the Security and Privacy app before updating anything, either OS or other applications. With the Security and Privacy app disabled the phone is running as it should on Oreo and I can update all of the other apps.
COME ON VERIZON... STEP IT UP... 3 DAYS OF FIGURING OUT THE EXACT ISSUE... VERIZON SHIPPED ME A 2ND PHONE BECAUSE THEY THOUGHT IT WAS HARDWARE AND THE IDENTICAL ISSUE HAPPENED. WHAT DID THEY DO NEXT? VERIZON SENT ME A 3RD PHONE WHICH IS PRESENTLY ON IT'S WAY TO ME.
EITHER STOP THE OREO UPDATE ON THE Z2 OR FIX THE SECURITY AND PRIVACY APP (WHICH WHO EVEN USES ANYWAY?)
I HOPE THIS HELPS PEOPLE. GOOD LUCK!!!
