My Samsung galaxy note 10.1 was stuck at the logo and could not boot...the stock recovery mode displayed E:failed to mount /efs (invalid argument) so I took it to a Samsung Service Centre that said the only way to fix it is to change mother board.
Thanks to you I now have a fully functioning tablet. Thank you very much and keep up the good work.
1. Flash CF-Auto root
2. Flash CWM recovery
3. Install Minimal ADB and fastboot (if you do not have Android tools sdk) this a small file.
4. Connect the device to the computer
5. Boot the device into CWM recovery
6. Choose Mount storage/mount system
7. Open Minimal ADB or command prompt
8. type: adb shell
mke2fs /dev/block/mmcblk0p3 ( skip to next step if fail)
mount -w -t ext4 /dev/block/mmcblk0p3
9. When you reboot you will see your screen with a yellow text..to get rid of it, install
root explorer (paid)
10. Navigate to /efs/factorymode and open as text
11. Change the (OFF) and replace with (ON) and save the file
When I type:
- exec '/system/bin/sh' failed: No such file or directory (2) -
Also, when I try to skip forward to the mke2fs step, nothing seems to happen there either. Am I doing something wrong? Any help anyone can provide will be greatly appreciated.
