Perhaps you neither have a S60v3 Nokia Smartphone nor a Windows Mobile 5/6 device with IR port but, like me, you do have a PSP-1000 model.
There is a homebrew application for the PSP-1000 models that allows it to be used as a Universal Remote controller to reproduce the IR Hack.
The only requirements are:
-A PSP-1000 model on Custom Firmware (AKA unlocked). Newer PSP models will NOT work as they lack in the IR port. If your PSP-1000 is not unlocked, google "pandora battery" as this is a relatively simple process to do.
-The application Universal Remote v1.2. Remember this is a 1.5 Firmware application, therefore it needs installing into PSP/GAME150 in order to make work in Custom Firmware.

-The winlirc compiled dump from the LG 105-201M service remote controller that includes the infrared impulses to open the EZ Adjust / IN-Start menu. [http : // w w w .pastebin.com/f4e0323b7
For those interested I have prepared a ready-made pack with all that you need that can be downloaded from http : //www.multiupload.com/KH8VCSQODE
Just uncompress it into the memory card and execute it from the GAME menu of the PSP. Once loaded, press SELECT followed by SQUARE. This should load a profile that has every PSP button (D-PAD and Square, Triangle, Cross and Circle) already assigned to the EZ adjust command.
Press any of them while pointing the PSP to the LG TV and you should see the box to enter the password that will grant you access to the Service Mode.
Any questions just ask
