I has a micromax bolt a58. It had low internal memory so I rooted it.Accidentally i deleted the native messaging app. After that i tried to copy all system files from another bolt a58 to my device. I changed permission of bin folder to 777. After that i rebooted my device. Now it is stuck in boot loop. I have tried to hard reset it clicking on wipe data/factory reset. It did not work so i clicked on wipe cache partition.It still does not reboot.I was wondering what is apply update from ADB. Can it be of any help? I had USB debugging ON.
