PAX A920 Password Reset Troubleshooting (Android... | terminalfaults.org

Technical Background:

The PAX A920 utilizes an Android-based operating system with proprietary payment processing applications. Password protection is implemented at the OS level and within the payment application. Incorrect password attempts or system errors can result in lockout. The Android System Recovery environment provides limited system-level access. Tampering with the system partition can trigger PCI-PTS security measures.

Symptoms:

User reports inability to access the PAX A920 system due to a forgotten or unknown password. Attempting password reset via Android System Recovery is the reported action.

Possible Causes:

User error: Incorrect password entry.
Software corruption: Glitches in the Android OS or payment application.
Data corruption: Corrupted password storage file.
Unauthorized access attempts: Repeated failed login attempts leading to lockout.
Firmware update failure: Interrupted or incomplete firmware update process affecting system settings.

Solution:

1

Safe Handling: Disconnect the PAX A920 from the power adapter and network connection.
2

Initial Assessment: Document the current system state, including any error messages or unusual behaviour.
3

Power Cycle: Reconnect the power adapter and attempt a normal system boot. Verify password entry.
4

Contact Support: If the normal boot fails, contact PAX technical support directly for authorized password reset procedures. DO NOT attempt unauthorized resets.
5

External Peripheral Check: Disconnect any attached peripherals (e.g., printers, scanners) to rule out interference.
6

Firmware Verification: If accessible, check the installed firmware version against the latest version available from PAX.
7

Data Wipe (Last Resort - Contact PAX Support): If all else fails, and only under the explicit direction of PAX technical support, consider a factory reset through the Android recovery. NOTE: This will erase all data and configurations on the device. Document every step taken.

Safety Warning:

Attempting unauthorized password resets or system modifications can trigger the device's anti-tamper mechanisms, rendering it permanently unusable and potentially violating PCI-PTS compliance. Do NOT attempt to open the device casing. Static electricity can damage the device. Ensure proper grounding when handling.

Prevention:

Implement strong password policies and ensure users adhere to them.,Maintain a secure record of administrator passwords.,Regularly back up system configurations (if supported by PAX).,Keep the device's firmware up to date with the latest security patches.,Provide adequate training to staff on proper device usage and security protocols.

Expert Tip:

Before performing any troubleshooting steps, try entering the password very slowly and deliberately, ensuring each character is correct. In some cases, touchscreen sensitivity issues can cause incorrect character input. Also, ensure the touchscreen is clean.
