Not possible to move your LT, sorry, you can unlock map files you have to work in another device.
JCV and ASR dont require to be unlocked.
JCV are provided in different resolution (high&low) to fit different displays, the one posted in the first page has a low resolution, not good for new series devices like 37xx . Should work in 850, but better to test it in simulation mode.
If you can post ASR ,our members would be grateful.
