On root directory of your rom, run:
croot
git clone https://github.com/baka-hokage/Signing-Script.git -b master scripts
bash scripts/generate_key.sh
After Generating the keys, instead of running brunch , run the following:
lunch <codename>
m target-files-package otatools
After itβs finished, you just need to sign all the APKs:
croot
sign_target_files_apks -o -d ~/.android-certs \
$OUT/obj/PACKAGING/target_files_intermediates/*-target_files-*.zip \
signed-target_files.zip
Now, to generate the installable zip, run:
ota_from_target_files -k ~/.android-certs/releasekey \
signed-target_files.zip \
signed-ota_update.zip
