OmaDm

This page will document knowledge about OmaDm. Note that some previous research of the over-the-wire behaviour of OmaDm has been done at Update_Service_Trace.

OmaDm seems to be involved in carrier provisioning and webOS OTA updates. Its working directory seems to be /var/lib/software.

It is called from UpdateDaemon, with the following arguments (found by using strings on the UpdateDaemon binary):

OmaDm -syncdata
OmaDm -revert_tree
OmaDm -set_domain
OmaDm -client
OmaDm -task
OmaDm -server
OmaDm -prepare
OmaDm -prepare %X
OmaDm -report_results

If you doctor and boot a device with the UpdateDaemon and OmaDm binaries disables, you get the following directory contents:

ModemFiles (empty directory)
SessionFiles (empty directory)
system_settings.info (contains localeCountry and localeLanguage settings)
tmp (empty directory)

If you run "OmaDm -syncdata", a couple of files appear:

DmTree.backup.xml
DmTree.xml

On a Veer, you also get the following error message:

[RdmInitCarrier: 423]: Unrecognized carrier ATT

The OmaDm binary seems to have support for Sprint, bell, ROW, and Verizon only. We're not sure whether this is a problem for AT&T or other carrier devices, but we'll assume that it is intentional for the moment.
