I don't have a MTP, but on HDK855, "fastboot oem select-display-panel
none"
combined with setting the physical switch to HDMI mode (which
switches off
the 1440x2560 panel) gets it to not setup the display at all (just the
fastboot command isn't enough).
Okay, I don't think we have anything equivalent on the MTP, but good to
know.
Actually I tried out this in SM8150 MTP and it works fine for me,
"fastboot set_active a; fastboot set_active b; fastboot set_active a;
fastboot oem select-display-panel none; fastboot reboot bootloader;
fastboot boot boot-sm8150.img"
Also I need to switch slots everytime like above, otherwise I always see
some error
while loading the boot image.
What is the error? If it is "FAILED (remote: Failed to load/authenticate
boot image: Load Error)" then flashing/erasing boot_a will make it go
away ("fastboot erase boot_a") for the next 6 or so "failed" boots.
Thanks,
Sai
