Cause: Baud rate mismatch between motherboard and LCD.
Fix: Re-flash the motherboard using 250000 baud rate. Then re-flash LCD. If still failing, your repack may be for a different Trigorilla board version. Use M115 in a terminal to check your board revision.
There is no official “repack” of firmware 1.3.5 from Anycubic. Version 1.3.5 is the final official Marlin-based firmware released by Anycubic. Any “repack” you find on random forums or file-hosting sites (Google Drive, Mediafire, etc.) is a third-party modification—usually a custom build of Marlin 2.0.x or 2.1.x that mimics the 1.3.5 features.
The original Anycubic Chiron firmware files were distributed in a messy state. Many users experienced: anycubic chiron firmware 135 download repack
A “repack” is a community-modified version of the official v1.3.5 firmware. Enthusiasts (often from Reddit’s r/AnycubicChiron or GitHub) have taken the source code, fixed the critical bugs, recompiled it, and packaged it with proper instructions. A good repack includes:
Without a proper repack, you risk turning your $500+ Chiron into a paperweight. Cause: Baud rate mismatch between motherboard and LCD
Even the best repack can have quirks. Here are solutions to the top three issues:

If you own the Anycubic Chiron (the big beast with a 400x400x450mm build volume), you know that stock firmware can feel... limiting. Lately, I’ve seen a spike in searches for “Anycubic Chiron firmware 1.3.5 download repack.”
Let’s cut through the noise. What are you actually looking for, and is a “repack” safe?
The download repack is fine for 95% of users. However, if you have modified your Chiron (all-metal hotend, direct drive, BLTouch instead of capacitive sensor), you should compile from source. Use Knutwurst’s GitHub repository and change:
#define NOZZLE_TO_PROBE_OFFSET -40, -10, -2.5 // stock sensor offset
#define DEFAULT_AXIS_STEPS_PER_UNIT 80, 80, 800, 93 // for stock extruder
Then recompile and generate your own firmware.hex. This is technically a "custom repack" but not the standard 1.3.5.
