[Q] Copy a system file over via stock recovery
I have a Nextbook 8 QuadCore tablet -- chipset RK3188.
I was editing the /system/etc/vold.fstab file to get the external sd to show up as the primary storage and made a mistake in the code. Now the tab locks up on boot up.
The tab is rooted, but I can't get adb to work from recovery (currently stock). I could possibly sideload the file via an update.zip.
What are my options? I just need to update the one file.
Super grateful for any assistance!
