[G 2014 Themes and Apps] lbssousa:
Thank you for the support!

I'm reviewing the ZIP file I've created, and I realized that file /system/app/FMRadioService/lib/arm/libqcomfm_jni.so is actually a symlink to /system/lib/libqcomfm_jni.so. How can I create this symlink on-the-fly (i.e. create empty folder /system/app/FMRadioService/lib/arm and then create the symlink inside it) by updater-script?

About script /system/etc/init.qcom.fm.sh, it essentially sets some properties and loads kernel module radio-iris-transport.ko. It calls a binary named /system/bin/fm_qsoc_patches (maybe I should include it in the ZIP). Look:

P.S.: How can I update the SHA1-Digest value of my modified updater-script in META-INF/MANIFEST.MF?
