I compared differences between ixtab's 5.1.2+extras, and his 5.0.0 (after updating to 5.1.2 and installing extras).

There are some differences (which actually make sense) that appear to be what causes 3G to not work in his 5.1.2 image.

There are two config files that are different.

Here are the files for working 3G:

Code:

/etc/kdb.src/yoshi/system/daemon/cmd/interfaces/interface2/hw_present:
RG002
40
<DATA>
1

/etc/kdb.src/yoshi/system/daemon/cmd/interfaces/interface2/force_down:
RG002
40
<DATA>
0

Here are the files for NOT working 3G:

Code:

/etc/kdb.src/yoshi/system/daemon/cmd/interfaces/interface2/hw_present:
RG002
40
<DATA>
0

/etc/kdb.src/yoshi/system/daemon/cmd/interfaces/interface2/force_down:
RG002
40
<DATA>
1

For a shorter path, /etc/kdb is a symlink to /etc/kdb.src/yoshi. (Thanks eureka!)

So, it looks like we should be able to enable or disable 3G at will by controlling those interface configs. Perhaps there is something similar to lock down wifi, for those who wanted to do that...

EDIT: Notice above that to enable 3G, you need hw_present=1 and force_down=0.
