Do you plan to add DM XOR key synthesis in the near future? Recently these controllers have started to appear and what is important is that the XOR mechanism is similar to SM32xx, i.e. XOR is modified by BB. You recently created a new XOR "DM_unknown(18336b_384p_xoredSA_ECC)_1775CE.xor" for our case. I have another case with this XOR, but everything goes wrong when it reaches BB - I checked and XOR is also applied to BB.

Is there a chance you will develop an automatic method for this? It can probably be done manually, but it's a lot of work.

Thanks in advance for your answer.

btw. this white horizontal white stripes are data, in DM, XOR before ECC.

ps. on attachment XOR comparison: top after BB cutout, bottom without BB cutout (pink-ECC, green-data area)

Can we have some 10-20 blocks from it? Preferably with xor key. I appreciate if you can send a link in ticket.
