Frequently Asked Questions
•What are the warranty implications of attempting a factory reset on an unresponsive terminal?
Factory resets, when performed through the documented methods, generally do not void the warranty. However, unauthorized attempts to open or repair the device will void the warranty.
•What type of data is typically lost during a factory reset on a payment terminal?
A factory reset will typically erase configuration settings, stored transactions (if any), and custom applications. Sensitive payment data is usually stored in encrypted form and might require specific keys for decryption, even after a reset.
•Can a firmware update be performed on an unresponsive terminal, and what are the risks involved?
Attempting a firmware update on an unresponsive terminal carries significant risk. If the update process is interrupted, it can further corrupt the firmware and render the device unusable. Only attempt a firmware update if instructed by Dejavoo support and with a stable power and network connection.
