DO NOT INSTALL: private X3 UC8279d diagnostic build
Pre-release
DO NOT INSTALL
Caution
This is not a general YACP pre-release. Do not install it.
This one-off recovery build was produced for a single user and one specific X3 currently being diagnosed. It forcibly treats every device as an X3 with a UC8279d display controller. Installing it on an X4 or an original UC8253 X3 will select the wrong hardware configuration and may leave the display unusable until another recovery flash.
Private support build for one device
YACP-1.6.2-yacp.18-xlarge.bin bypasses all automatic device and display-controller detection. It exists only to determine whether the affected user's recovery process can start a firmware that directly selects the X3 UC8279d driver.
After SD initialization and before display initialization, it unconditionally writes YACP-X3-DIAGNOSTIC.txt to the SD-card root.
Unless you are the user who was explicitly sent this release as part of the ongoing diagnosis, do not download or flash this firmware.
