Trying to shake hack that got into my Google & took all saved passwords, gmail addy’s, etc. Found answer, but lost tab.. Step 1: Shut off phone. Step 2: Tried to get to reboot menu pressing volume down and power together. It worked! Then I went to ADB, but got message I didn’t understand. Didn’t know next step, so hit factory data Reset (which didn’t get rid of generic Android 10 system on this phone). Anyone able to give me step by step instructions "How To?"
