bootloop with dtbo

[amackpro]

i tried unpack and repack dtbo.img in xiaomi marble

it successfully unpacks and repacks dtbo but somehow without any changes done into the files the device never boots
always on animation for some reason

cmd used for unpack and pack

./gradlew unpack dtbo.img
./gradlew pack

did try dtbo.img.clear and signed both

Can you attach the dtbo.img being used?

well issue is now fixed
thing is linux default DTC compiler is RIP ( using Ubuntu23.04)
when i compiled with google DTC ,it compiled fine and booted successfully

please add google dtc into tool
dtc.zip

I am facing exact same problem, the recompiled dtbo is same as original one.

Can you please share how to replace default compiler with google dtc?? and compile successfully?

HI @amackpro , thanks for the great work.
I am adding a config entry in bbootimg/src/main/resources/general.cfg to support user specific dtc binary:
the default value is

dtcBin = dtc

you can change it to something like this:

dtcBin = /usr/local/bin/dtc

But I am curious how the "dtc" binary causes the difference, can you attach the "good" and "bad" dtbo image you've tried?
