I erased a file called .sh from the system/bin directory on my android jellbean device now it doesn't work properly. I can connect via USB and adb but cannot access the shell. How can I replace the missing time and gain access to shell

    Reflash system partition, or if you have access to that standalone sh file then use a custom recovery to copy it under /system/bin. Next time, make custom recovery based backups if you decide to modify anything outside of /data partition.

If you erased just the sh binary then you still be able to run others binaries, here a script I made that may fix it (you need the sh bin file and terminal emulator):

/system/bin/su
/system/bin/mount -o rw,remount /system
/system/bin/cp /sdcard/sh  /system/bin
/system/bin/chmod 755 /system/bin/sh
/system/bin/mount -o ro,remount /system
/system/bin/sh

Put your sh file on sdcard, and write this script with filename ending .sh, after open a file explorer click on the script and select terminal emulator to run the script.

  • If you can't boot the device, then the only solution is flash the stock system partition, if your device supports fastboot try flash from it.

  • I can boot device but cant use terminal emulator on it because I don't know how to get access to it from a host device

  • Try install Termux (play.google.com/store/apps/details?id=com.termux) and run the script (you may also need to run this command before: termux-setup-storage ).

  • I appreciate your answers however I don't think you fully understand all I can do with the device is boot it upand put in the password. I can't install apps. I'm tryind to figure out how to use another device or a computer to gain access via adb but every time I connect to it and type in adb shell it says shell not found because I deleted the sh file
