OTA Updater for LichUI

LichUI includes an OTA (Over-The-Air) updater to keep your device updated with the latest improvements and fixes.

What are OTA Updates?

OTA updates allow you to download and install new versions of LichUI directly from your device, without the need for a computer. However, there are updates that will require a clean installation, when there is a binary change in the stock firmware.

Types of Updates

Updates via OTA

• Sames Bootloader and Binary

Download speed

• We currently do not have our own server, which causes OTA downloads to be slow depending on the time and region.

• If you would like to support the project, you can make a donation to purchase a better server (the monthly price per server is over $10 USD), or if you have your own server, you can collaborate with the project.
