- Fix ZIPROOT path from 3 to 4 levels up (../../../../) - Add path validation before install - Replace simple cat append with key-based dedup for build.prop (skips existing keys to prevent duplication on re-flash) - Update AGENTS.md and README.md to reflect the changes

# TWRP Flashable Zip — CB-C6s-STU-GSI-Fixes
|
||
#
|
||
# This is a shell-script update-binary. TWRP extracts the zip,
|
||
# sets the working dir to that temp location, and runs this script.
|
||
# The updater-script is a dummy — all logic lives here.
|
||
#
|
||
# What it does:
|
||
# - Appends build.prop entries to /system/build.prop (not replace!)
|
||
# - Installs goodix_ts.idc to /system/usr/idc/
|
||
# - Installs sensor_config.xml to /vendor/etc/
