Since there's 2 LG TVs in the household, I figured I might as well make a separate page for them.
- 55UH605V-ZC - 3.10.19-p.45.dharug.k2lp.2 - FW 05.30.60 - webOS 3.3.4
- 55UK6200PLA - 4.4.84-p.84.gomolsha.lm18a.1 - FW 05.20.15 - webOS 4.2.0
There's some ways to jailbreak some LG TVs - XDA, RU forum
You can get SSH access by following instructions here.
cat /var/run/nyx/device_info.json - has mac addresses and TV model name among other things
cat /var/run/nyx/os_info.json - webOS version. The version the TV displays is FW version, not webOS version!
Code this as Base64 file called 'query" and execute the curl command to test connection to the update server
<REQUEST> <PRODUCT_NM>webOSTV 4.0</PRODUCT_NM> <MODEL_NM>HE_DTV_W18A_AFADABAA</MODEL_NM> <SW_TYPE>FIRMWARE</SW_TYPE> <MAJOR_VER>04</MAJOR_VER> <MINOR_VER>10.45</MINOR_VER> <COUNTRY>GB</COUNTRY> <COUNTRY_GROUP>EU</COUNTRY_GROUP> <DEVICE_ID>20:17:42:14:b7:43</DEVICE_ID> <AUTH_FLAG>N</AUTH_FLAG> <IGNORE_DISABLE>N</IGNORE_DISABLE> <ECO_INFO>01</ECO_INFO> <CONFIG_KEY>00</CONFIG_KEY> <LANGUAGE_CODE>en-GB</LANGUAGE_CODE></REQUEST>
curl -X POST -A "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" -d @query http://snu.lge.com/CheckSWAutoUpdate.laf
If query is wrong, server cuts connection - curl: (56) Recv failure: Connection reset by peer
Server also times out very often.
Queries and responses are Base64 encoded.
