So now let’s make it clearly. for T-R42 model, factory has changed the PCBA board from B351 v1.0 to B351 V2.0. so how to know which boards you have. here is the method.
Check the back of T-R42, you will find a S/N number, if the S/N number start as T-R42, then means it is B351 V2.0 board, and you need the above firmware. if the S/N number start as BX, it means you have the B351 v1.0 board, and you just can use the old stock firmware here and all the other custom roms.
We have worked with custom rom developer, and will release the custom rom support for the new V2.0 board, please stay tuned.
