Bootloop after modification of "/system/bin/playlpm" file Modification of playlpm file sets my Samsung Galaxy S4 Mini I9192 into boot-loop.
Instead of normal booting, it goes back to battery charging screen without animation, reboots again and keeps repeating this cycle. It happens only at the attempt to auto-start the phone by connecting a charger. Otherwise phone is fully operational.

Is there any option of "reboot" or similar command that forces S4 Mini to come out of the bootloop?

Note: /system is write-protected in Galaxy S4 Mini and needs to be remount to save something on it.  Used command: mount -o remount,rw /system
You'll need to get it in recovery mode and re-flash it. There's a tutorial here if you need it.
If that doesn't help, I'm afraid the only option will be to carry it to service for repair.
