adb Read-only file system

adb root;adb remout
之后

adb push libtinyalsa /system/lib/libtinyalsa.so
adb: error: failed to copy 'libtinyalsa' to '/system/lib/libtinyalsa.so': remote couldn't create file: Read-only file system
libtinyalsa: 0 files pushed. 0.6 MB/s (34492 bytes in 0.054s)

adb disable-verity
adb reboot //important

再重新执行上面的就可以
