OK, I will make the Orenge UK ROM for X02T.
However, there are two patterns in the ROM.
One is ROM that converts Orenge UK ROM into tss as it is. If you flashed this ROM, your X02T need the Pin method (1 & 2) each boot times, like "xandetonetti".
Another one is ROM that adds boot of T01A65 ROM to Orenge UK ROM and converts it into tss. If you flashed this ROM, your X02T have normality boot, maybe. But, there are the risk that it might become a brick. (Because no one still has tried.)
I will make these two ROM. And, I try Encryption of tss by 44460046 Key. If it failed, I will make ROMs with another Key. And, if we find the key of X02T tss, I will make about-X02T.tss.
Please wait a few days it. (My net environment is bad.)
There is no necessity for newly making registry Key. It must already be. Then, the name of ExtROM might be different from EXT_FLASHDRV. Or, ExtROM is invisibil maybe because of being locked. In that case, I do not understand the unlock method.
By the way, when I saw the inside of ExtROM in the binary, it was empty(TFAT12).
