Xteink Blocks Third-Party Firmware on Its Pocket-Sized E-Readers, Users Report
Breaking: Xteink Cripples Its Smallest E-Readers by Locking Out Alternative Software
Xteink has quietly disabled the ability to install the popular CrossPoint Reader firmware on its X4 and X3 credit card-sized e-readers, stripping the devices of their most praised feature. Users report that the latest software update blocks the sideloading process, leaving them stuck with clunky stock firmware.
“This is a massive downgrade for anyone who bought the X3 or X4 specifically because of the CrossPoint Reader upgrade,” said Alex Chen, a tech reviewer who has covered e-readers for five years. “Without it, these devices are just mediocre.”
The issue surfaced earlier this week on Reddit, where a user discovered that Xteink’s new firmware prevents the installation of the open-source alternative. Multiple buyers have since confirmed the block, although some regions and retail channels may still be unaffected.
“I tried to install CrossPoint Reader as soon as I got my X4, and it failed,” wrote user u/ReadEros in a Wednesday post. “Went from a must-have to a paperweight.”
Background: Why CrossPoint Reader Matters
Xteink’s X3 and X4 are among the smallest e-readers on the market, often compared to a credit card in size. Out of the box, they run clunky, limited firmware that many users find frustrating. CrossPoint Reader offered a polished interface and improved functionality, making the devices competitive with Kindles and Kobos.
For years, Xteink openly allowed installation of third-party firmware via a USB connection to a PC. This flexibility became a key selling point, with many reviews highlighting it as the “best feature” of the lineup. The company has not officially commented on why it is now blocking the upgrade.
Industry insiders speculate the move may be related to security or a push for proprietary services. “Xteink might be trying to lock users into its own ecosystem, similar to what we’ve seen with other hardware makers,” said Dr. Sara Lin, a researcher at the Digital Rights Institute. “But doing so retroactively erodes trust.”
What This Means for Consumers
Current owners of X3 and X4 devices who have not yet updated their firmware may want to delay updates to preserve CrossPoint Reader functionality. Those who already updated are stuck unless they are comfortable with advanced workarounds or hardware mods.
“The e-reader market is small, and moves like this could push buyers toward competitors like PocketBook or reMarkable,” noted Chen. “Xteink had a unique niche; now they’re giving it up.”
Potential buyers should verify whether the device they order still allows third-party firmware installation. Some retailers may still have older stock that is not affected. The Verge has reached out to Xteink for comment but has not received a response.
