How to Hard Reset Sony Xperia Z3 Tab Unlock Password Screen Lock Remove

This method requires a computer and Sony's official software, which can sometimes bypass a forgotten lock, especially if it's a software glitch, or help if the hardware button method is difficult.
Steps:
Download and install Sony Xperia flasher Companion:
On your computer, go to the official Sony support website and download the "Xperia flasher" software (it replaced the older PC Companion).
Install the software on your computer.
Launch Sony flasher:
Open the Xperia Companion application on your computer.
Connect your tablet (in a specific state):
On the Xperia Companion software, look for an option like "Software repair" or "Repair my device." Click on it.
The software will guide you through the process. It will likely ask you to:
Power off your Sony Xperia Z3 Tablet.
Connect the USB cable to your computer.
While holding down the Volume Down button on your tablet, connect the other end of the USB cable to your tablet.
Keep holding the Volume Down button until the software detects the device.
Follow on-screen instructions:
Xperia Companion will then download the necessary firmware and reinstall the operating system on your tablet. This process can take a significant amount of time depending on your internet speed.
Do NOT disconnect the tablet until the software repair process is 100% complete and the software tells you it's safe to do so.
Tablet will restart:
Once the repair is finished, your tablet will restart. It will be restored to its factory settings, and the screen lock will be removed.
Troubleshooting Tips:
If you see "No Command" screen: After the Android logo appears with "No Command," try briefly pressing the Power button and then quickly pressing the Volume Up button (release both) to bring up the recovery menu.
Tablet won't power off: If the screen lock prevents you from powering off, you might need to let the battery drain completely, then charge it and try the hardware button method immediately after it powers on.
Still stuck? If these methods don't work, there might be a more severe software issue or a hardware problem, and professional assistance from a Sony service center or a reputable repair shop might be necessary.
Remember, a hard reset is a last resort when you've forgotten your screen lock and have no other way to access your device.
