It not should work at all, does bootloader unlocked?
Or maui can boot it? As can see, from brom, device rejects anything and asks for SLA AUTH. If it not enter from preloader mode, then meta will not work.

IN 6A both IMEI's and MAC's, SN are RSA signed.

Ok, got it.
Will fix that in near update-two.

About first imei then - seems as it common xiaomi bug or feature, when first null and second work.

Writing first one will enforce security verification and sure, it will fail, because signature removed or wrong.
Signature paired to device CPU.

Mr. Jaydi, I always managed to see that they only work tray # 2 since tray # 1 gives an error
