Fire OS 5 mount -o remount,rw fails as root This is regarding Amazon's port of Lollipop. AFAICT, other similar questions are regarding Jelly Bean and earlier plus non deal with Fire OS.

I'm working with a rooted Amazon Fire TV/2 running Amazon's Fire OS 5, its Lollipop port. I'm unable as root to mount /system as r/w.

mount -o remount,rw /system fails with "mount: Invalid argument"

/dev/block/mmcblk0p13 is linked to /dev/block/platform/mtk-msdc.0/by-name/system

/dev/block/platform/mtk-msdc.0/by-name/system is mounted at /system

Mounting /system r/w (as root) worked fine under JB.

How can I remount /system as r/w under Amazon's Lollipop?
You can also try with: mount -o rw,remount /system . For some devices this works fine.

I just did the test now on my device, Nexus 6P. As you see, both commands are valid and system applies them. Why was my answer down voted?
