[Nexus 7 (2013) Original Android Development] followmsi:
Thanks for the nice release .. just have updated !

But I do have the same problem installing secondary systems.

Update.zip with "package_extract_file("system.img", "/dev/block/platform/msm_sdcc.1/by-name/system");" are not booting as secondary.

More details here .. http://xdaforums.com/showpost.php?p=66468858&postcount=1303

Why it's not booting as secondary ? .. the same Update.zip works on Flo hardware. ( for internal )

Here is the multirom-log.txt ..
