SamyGO

I searched for injectso and gdbtrick, but i read this: THIS PROJECT IS DESIGNED FOR SAMSUNG LExxB65x T-CHL7DEUC MODELS WITH 2005.0 FIRMWARE. ...

yes, firwares are pre-patched with "-a" (advanced) option. But sure you can use your own patched 3000.G firmware aswell. As you wish
For injectso or gdbtrick search forum, here is some topic with well discussed object.

I was thinking to use SamyGO Firmware Patcher in advanced mode to patch 3000.G fw, is the same?
What are gdbtrick and injectso? I searched on the wiki but there's nothing

... script, where you can add your wanted autostart apps (use gdbtrick or injectso for this goal). Only unrestricted firmware can be patched w/o issues.

I think this someone should create a patch for this. As we have such patch for B and D series, it should be enough just to port it.
We testing new method to patch exeDSP in memory. THis is like injectso or gdbtrick we know since b series...

My advice: you could use gdb (or maybe injectso), but check what apps does not freeze your TV - those could be started automatically.
Start your script manuall from console and if no freezes or rebots, just then add this to SamyGO.sh

Hi, check for injectso or gdbtrick. Also Extensions have injectso init script, so you could setup it and from SamyGO.sh call just only rcSGO

You can`t record analog channels, just digital.

For autostart look forward for injectso or gdbtrick

you can do this using gdbtrick or injectso binary. I load my apps using SamyGO Extensions with enabled \etc\init.d\90_90_injectso.init with correct path(es) to the app(s) inside. (line: libraries="NOTHING" # add your libraries here )

... need to make custom SamyGO.sh with autostart of your wanted game - use injectso or gdbtrick for this goal.
