For AO3 fanfiction readers

X3 ~ X4 ✓ Risk: High

Best for: Heavy Archive of Our Own readers with an unlocked X4.

GitHub repo Flasher / tool

What it adds

  • An AO3-styled library browser with per-fic status icons (unread / reading / waiting / new chapter / finished).
  • Checks AO3 for and downloads new chapters on-device over WiFi — no PC or sync tool needed.
  • Pin longfics to the homescreen so oneshots don’t bury them.
  • Built on CrossPoint’s reading engine, so the core reading experience is solid.

AvesO3’s AO3 Library — fics with metadata squares, tags, chapter counts and update dates.

How to install

via web flasher (unlocked X4 only)
  1. 1

    Download AvesO3_1_2_2.bin from the AvesO3 releases page.

  2. 2

    Connect an unlocked X4 by USB-C and open xteink.dve.al.

  3. 3

    Flash the .bin. To revert: flash official firmware, or "Swap boot partition" at xteink.dve.al/debug.

Locked devices & AvesO3

Requires an unlocked X4 — flashing via the unlocker tool is untested, and X3 support is unverified. Single-maintainer and very new, with Issues disabled.

How to go back

For AvesO3: To revert: flash official firmware, or use "Swap boot partition" at xteink.dve.al/debug.

  1. 1Re-flash stock — the same web flasher offers official Xteink firmware.
  2. 2Restore a backup — “Write full flash from file” if you saved one first.
  3. 3Swap boot partition — a quick rollback at xteink.dve.al/debug.

On a locked unit you lose the USB safety net — that’s why locked devices stick to CrossPoint/CrossInk.

Heads-up: Very new, single-maintainer, Issues disabled. Requires an UNLOCKED device — flashing via the unlocker tool is untested. X3 is unverified.

New to flashing? The mechanics are the same across forks. See the five flashing methods on the directory, or the step-by-step flash CrossPoint without panicking guide.
