Use hex patch for dtb patching #1

Closed Zackptg5 closed 6 years ago

Zackptg5 commented 6 years ago

Use hex patch for dtb rather than relying on magisk's bugged method: Replace ',verify' with nothing: ,verify = 2c 76 65 72 69 66 79 verify, = 76 65 72 69 66 79 2c verify = 76 65 72 69 66 79

Perhaps a simple sed patch would do the trick? sed -i -e 's/\x2c\x76\x65\x72\x69\x66\x79/\x00\x00\x00\x00\x00\x00\x00/g' -e 's/\x76\x65\x72\x69\x66\x79\x2c/\x00\x00\x00\x00\x00\x00\x00/g' -e 's/\x76\x65\x72\x69\x66\x79/\x00\x00\x00\x00\x00\x00/g' $overlay/dtb (Assuming it's unpacked properly and stuff)

With my OP5T. This is what is extracted:

I'm assuming zImage in split_img is where dtb lies?

For my reference: https://source.android.com/devices/architecture/dto/implement

dtb is typically found in zImage in split_disk, dtbo is a separate partition/img. Both are imgs and are patched the same way

Possibly done with https://github.com/Zackptg5/Disable_FEC_DmVerity/commit/4d6bdb47a7db29a4ecf081acbad477d0f3f665fb

Zackptg5 commented 6 years ago

Forgot that android sed seemingly can't do hex patching

Think I got it with this commit e2232d225ce5cd843b664edead1958c6d08a2ff7
