patch for mt6893,can this tool remove signature verification?

[dysf888]

I tried to modify the logo to remove the logo of the unlocked device, but when I flashed the modified Logi.bin, the device would not turn on and the screen would remain black.I guess LK has signature verification on the logo during the startup phase, but I don't know how to modify files.

LK.img get from official MIUI package LK(a/b).bin get from mtkclient device RedMi Note 10 Pro MTK 1200 (mt6893)

I believe LK is also verified. Have you tried altering at least one bit and then reflashing the modified LK onto the device to confirm if it can boot with the patched LKs?

Try this LK image. I basically forced img_auth_stor (which seems to be used to verify logo in your case) to return 0 (success) no matter what. For future reference, you can use the following JSON:

{
    "fastboot": {
        "2de9f04fadf5ac5d": "00207047",
        "f0b5adf5925d": "00207047"
    },
    "dm_verity": {
        "30b583b002ab0022": "00207047"
    },
    "orange_state": {
        "08b50a4b7b441b681b68022b": "00207047"
    },
    "red_state": {
        "f0b5002489b0": "00207047"
    },
    "img_auth_stor": {
        "2de9f0470f469046": "00207047"
    }
}

Hey, I'm really sorry but I didn't get to try it out. I accidentally spilled some Coke on it. Anyway, thanks again for helping me.
