At 23 March 2011 I have started a project named OpenLGTV BCM (OpenLGTV for Broadcom platform based TVs).
It's a part of firmware replacement for 2010 Broadcom BCM3549/3556 based TV models.
Speaking in other words - it's a small Open Source Linux distribution based on GPL licence which doesn't remove any of LG firmware features, just adds more.
Most part of LG firmware is still running and is needed to have tuners input, hardware media player and TV screen picture and audio output.
LG haven't released hardware drivers to make it possible to build complete firmware replacement.
== Supported platforms ==
It's designed for all Broadcom based 2010 2D and 3D LG TV models. (all countries are supported)
Check this page for supported models list:http://openlgtv.org.ru/wiki/index.php/Achievements
If you have not yet supported model, please provide us a firmware backup first for making support of yours TV.
Support for 2011 SmartTV models was planned to be done with OpenLGTV BCM 0.5.0 but as there's more security at bootloader it wont be available too soon.
== Prerequisites ==BusyBox shell access via serial connection to TV is needed to be able to install any OpenLGTV BCM version for the first time.

== WARNING ==
Before trying it make backup of your current firmware first!
(versions starting from 0.4.0-beta2 make properly automated backup of all partitions before installation proceeds)There's no warranty for using custom firmwares or instructions mentioned here. YOU USE IT ON YOUR OWN RISK.
Read everything carefully, follow official project thread and linked wiki pages. Even small mistake can brick TV.
Althrough we try to help in most cases we don't take responsibility for possible damages on your devices!Up to now LG firmware Network Upgrades were safe but since December 15th 2011 LG started to deliver new security via Network Upgrades.
This new security disables OpenLGTV BCM so network upgrades shouldn't get accepted since now.
OpenLGTV BCM 0.4.3 is not compatibile with the latest firmwares with new security - use 0.5.0-rc1 instead.Currently the 0.5.0-rc1 is recommended.
Any feedback as comments, bug reports, feature requests are always welcome.
Please include these informations in feedback:
1. Model name
3. Firmware version (both OpenLGTV BCM version and LG firmware version)
[4. Boot logs] (logs not needed if everything worked without problems)
Info: thread post started with version 0.1.0, updated to 0.5.0 later.

(with download link)WARNING
- If anyone would like to get back to original LG firmware (to remove OpenLGTV BCM) unlike I said earlier, full epaks shouldn't be used for that. There is high risk of breaks with such epaks (even with flashing them over original LG firmware as upgrade but with OpenLGTV BCM risk might even increase due to more running processes). It's not completely confirmed yet but I wanted to warn you just in case.
Attachment removed - use 0.5.0-rc1 instead of 0.4.3 to not get potential problems on newer firmwares.
