nexus 5x stuck on Google screen after replacing one of the system shared libraries

Question

My nexus 5x works fine until I changed some share library in system partition:

adb push out/target/product/bullhead/system/lib/somename.so /system/lib/somename.so
adb reboot

then my nexus 5x is stuck on Google screen on boot. But when I cleared data, my nexus 5x works fine again:

fastboot -w && fastboot reboot

I also find that system.img can't be flashed alone, I must wipe data using fastboot -w when I flash the system.img, or it will stuck on Google screen on boot. Anyone know how to solve this?

Answer 1

I have done a lot, and finally it worked, I'm not sure which one of these solved my problem, but I believe it has something to do with:

fastboot flash userdata userdata.img

Hope it will work for you.
