Pivos – Rebuild and Sign .img file

Finally you have to rebuild the image, to do this first compress the new image file with zip: zip -r update-unsigned.img * And then you have to sign that update-unsigned.img java -Xmx1024m -jar signapk.jar -w testkey.x509.pem \ testkey.pk8 update-unsigned.img update.img I extracted the signapk.jar, testkey.x509 and testkey.pk8 from the buildroot. Have fun with this!
