LG H901 Unlock Help By Writing New System Files?

Hi, I have a already Working Permanent Unlocked LG H901 that already has the TMO Mobile Device Unlock App automatically removed after the factory unlock was successful by the carrier and wanted to know if I can copy over the system or any of the files from inside this phone into another phone H901 to Sim Unlock it using the latest version of the Octoplus LG Tool that is similar to how your Octoplus Samsung software works with Samsung phones by writing the Certs & Etc of another phone.There is a local phone repair guy that claims that they have a repair tool that unlocks the phone during the IMEI repair operation but I do not know how he does this since the system of the phone is locked by the TMO Mobile Device App. Thank you guys for any help possible.
