Here, model is mediacenter model, for ex. s410; os is OS type (android or linux-qt).
Unpack firmware and make changes
$ mkdir firmware $ unzip -o -q tvip_firmware.ota.zip -d firmware $ ls -l firmware/ total 8272 drwxr-xr-x 6 vovan staff 204 7 фев 13:55 META-INF -rw-r--r-- 1 vovan staff 3870617 29 фев 2008 boot.img -rw-r--r-- 1 vovan staff 360464 29 фев 2008 bootloader.img drwxr-xr-x 19 vovan staff 646 7 фев 13:55 system
For Linux firmware, roofs is located in system folder.
/usr and /home in Linux-Qt firmware are SquashFS images.
If you need to add symlinks, you should edit the following file: META-INF/com/google/android/updater-script
Compress and sign new firmware
Compress:
$ cd firmware $ zip -r ../unsigned_tvip_firmware.ota.zip . $ cd ..
To sign a package, you will need:
- Java Development Kit OpenJDK или Oracle JDK
- singapk.jar tool and platform keys sign_tools.tgz
Sign OTA:
$ java -jar signapk.jar -w key.x509.pem key.pk8 unsigned_tvip_firmware.ota.zip signed_tvip_firmware.ota.zip
** Please note: the latest TVIP Mediacenters (v.501, v.110, v.6xx), that utilize firmwares with .signed.ota.zip extension, can not be manually signed. Please, contact TVIP sales department or your ressaler if you want to use modified firmware with these mediacenters. **
