CrossPoint-based fork
CrossPet
v1.8.4 · MITGamified reading + Vietnamese
Best for: Readers who want a fun, feature-dense build, with the broadest Vietnamese support in the scene.
- A Tamagotchi-style virtual chicken that grows as you read (~20 pages feeds it); streaks and stats.
- Mini-games (chess vs. AI, Sudoku, 2048, Minesweeper), flashcards with spaced repetition, weather, Pomodoro.
- Full Vietnamese localization with diacritic fonts; custom SD-card fonts.
- Runs on X3 as well as X4, with KOReader sync and OTA.
CrossPet runs on the Xteink X3 and X4. The install is 3 steps via web flasher, start to finish:
- 1
Connect the X3/X4 by USB-C and unlock it.
- 2
Open the flasher at xteink.dve.al and flash the CrossPet firmware (or grab a .bin from releases).
- 3
Optional: drop custom font .bin files into /fonts/ on the SD card.
First flash? The mechanics are the same across every fork. Compare the five flashing methods on the directory, or follow the step-by-step flash CrossPoint without panicking guide.
CrossPet is a medium-risk flash. Settle two things before you touch the flasher: whether your Xteink shipped locked, and how you'd get back.
Locked devices & CrossPet
Unlocked devices only, and a genuine trap on locked units. CrossPet ships no standalone SD update.bin and is not one of the two firmwares the OTA Unlocker supports. Owners who got CrossPet onto a locked X4 report being stranded: USB is dead, CrossPet has no in-app SD update, and OTA cross-flashing fails (issue #28; the SD-flashing fix PR #29 is still open). Do not flash it on a locked device. If you are already stuck, the CrossPoint team now publishes Escape Hatch, a minimal SD-card recovery flasher, and the community documents flashing it via the OTA Unlocker to get a locked X4 back onto CrossPoint. A rescue path exists now, but treat it as a last resort, not a licence to flash.

How to revert CrossPet
On an unlocked Xteink you have three ways back:
- 1Re-flash stock. The same web flasher offers official Xteink firmware.
- 2Restore a backup. “Write full flash from file” brings back the exact prior state, if you saved one first.
- 3Swap boot partition. A quick rollback at xteink.dve.al/debug.
On a locked unit there is no USB safety net. That is why locked devices stick to CrossPoint/CrossInk.
The one caveat: Feature-heavy and playful rather than minimal. The BLE remote build is beta and disables some rendering to fit RAM. Never flash on a locked device. Owners get stranded (issue #28). The community-documented Escape Hatch rescue is a last resort, not a safety net.
Owner kit
A light and a case after setup
X3 and X4 ship without a front light. A clip-on is the usual first add-on.
