The installation pages of devices that have an EFS partition should advise to backup the EFS partition so users can restore the partition in case of corruption. This could prevent #1467 and would not require to install the proprietary stock images.

The page detailing the backup process should also include information about the necessary permissions the files should have to prevent network issues.

This has been done (history in #1930) for most of the devices.

Only the following devices still need to be added:
  • Galaxy Note (N7000)
  • Galaxy Tab 2 7.0 (P3100)
  • Galaxy Tab 2 10.1 (P5100)
  • Galaxy Note 8.0 (N5100)

We now have two different wiki pages related to backing up the EFS partition:

The Research based page seems to contain information that says that the other page needs to be updated because the commands at the other page stopped working and the backup were corrupted. If this is the case, we should update the BackupTheEFS page or ask that people test out the new commands on the Research page so we can determine if such a change should be made.

Additionally, we should add information related to best practices related to restoring one's EFS partition and link to it on the BackupTheEFS page.

  • The BackupTheEFS page is user instructions to backup the EFS.
  • The BackupsResearch is a documentation for the first page: It explains what worked and what didn't. Most users don't need that level of details, but people working on writing the user instructions do.

The bug is fixed. The issue is

adb shell "cat /path/to/partition" > partition.img
, but
cat /path/to/partition > partition
is supposed to work.

To use adb pull directly on the partition we would need to validate that the '*' are working in such context.
