Independent Xteink guides
Buy the right Xteink. Then keep it running.
PocketInk is the independent how-to hub for Xteink pocket e-readers. Picks first: the X3 you can buy, the front-lit X4 Pro, the discontinued X4, and the China-only S4. Then the flash steps, first-week setup, book transfer, and repair notes after I run them on a real unit. Not affiliated with Xteink.

The kit bag
What to add after you buy
X3 and X4 have no front light. A clip-on is the usual first add. Skip it if you bought the X4 Pro.
After you pick a model
New owner, firmware, or a hardware compare. Open the lane that matches what you're doing next. Each link is an owner-tested guide or a hub that lists every option.

What PocketInk covers
Three jobs: pick the right Xteink, keep it running on custom firmware, and fix or kit it when something breaks. Every guide is written so a section still makes sense if an agent quotes it alone.
Buy and set up
Model choice (X3 vs X4 vs X4 Pro vs S4), locked versus unlocked buying, first-week setup, and how to get books onto the microSD card.
Flash firmware
CrossPoint is the usual base. The directory compares the forks (Papyrix, Microreader, CrossInk) and the flash methods (web flasher, esptool, SD card).
Repair and accessories
Cracked-panel math, X3/X4 replacement walkthroughs, and the few add-ons that matter (clip-on light on the X3/X4, skip it on the Pro).
Firmware directory
CrossPoint is the usual flash. The directory starts with that base, then the forks, and notes which model each one fits.
Latest guides
Setup, flashing, buying, and comparisons, newest first.
Review
Xteink X4 Review: Should You Actually Buy One?
No Libby, no store, no USB transfer, no front light. Some units ship locked. The X4 is discontinued. Run this checklist before you buy used, or an X3 or X4 Pro.

Xteink Pogo Pins vs USB-C: What's on the X3, X4, and X4 Pro
USB-C is the plug, USB 3 is a data standard, and pogo pins are the magnetic contacts on Xteink X3 and X4 Pro. The original X4's USB-C was not USB 3 file transfer.
