v1.12.1 is a small patch release on top of v1.12. It corrects the configured battery capacity for the T-Deck Max from 1500 mAh to 1400 mAh, matching the cell actually shipped in the device. This improves the accuracy of battery percentage and runtime estimates on the Max.

What's Changed in v1.12.1

T-Deck Max battery capacity -- 1500 -> 1400 mAh

The Max's battery capacity was set to 1500 mAh; it is now 1400 mAh to reflect the real cell. No other behaviour changes.

All other devices and features are unchanged from v1.12..

Despite the LilyGO T-Deck Max readme reflecting 1500mAh, I've removed the battery from my Max (to put in a 2500mAh battery with a custom case) and can confirm my T-Deck Max battery was actually the same 1400mAh used in the T-Deck Pro.

First-Time Flashing

Each build comes in two forms:

  • <name>-merged.bin -- bootloader, partition table, and firmware in a single image. Flash at address 0x0. Use this for a first-time flash, when coming from other firmware, or if a device will not boot after an update.

  • <name>.bin -- application firmware only. Use this to update an existing Meck install, including OTA updates from your phone (Settings -> OTA Tools).

The partition layout supports dual OTA slots, so the previous firmware remains on the inactive partition as an automatic rollback target if a new image fails to boot.
