Some of Xteink’s major credit card readers are losing their best features

In the past, we noticed that some users who tried to use third-party firmware faced issues like poor optimization, frequent crashes, and screen crashes. Some users who later reverted to the official firmware encountered problems such as not being able to access reading records, Wi-Fi not being activated, and the book transfer page not being opened, and then requested their recovery.

We are very concerned that this may affect your experience and the security of your device. At the same time, flashing the firmware yourself will void the warranty, making future updates difficult. Therefore, for new devices that have recently been shipped, we have carefully added restrictions to the monitoring function.
