Some of Xteink’s credit card-sized e-readers are losing their best feature

Previously, we noticed that some users who tried using third-party firmware encountered problems such as poor optimization, frequent crashes, and even screen damage. Some users who later reverted to the official firmware experienced issues like being unable to access reading records, Wi-Fi records not opening, and the book transfer page failing to launch, and subsequently applied for official repairs.

We are very concerned that this may affect your user experience and device safety. At the same time, flashing firmware on your own will void the official warranty, making future repairs more troublesome. Therefore, for recently shipped new devices, we have cautiously added restrictions to the flashing function.
