Update via partition
It is possible to update OS and application without a USB stick (not valid for ISO-V2).
For this, the files have to be put into a special folder that might have to be created at first.
For A3/A6G1: /opt/var/update
This folder might have to be created first:
mkdir /opt/var/update
For A6g2/A8/B3/B4: /var/shadow/update (without update images or uImage files)
For A6g2/A8/B3/B4 you can also put a uImage file into: /var/shadow/boot
To use the partition, it needs to be remounted as read-write first:
mount –o remount,rw /var/shadow
