I recently ditched my phone's stock ROM for a lightweight custom one. After transferring my files over, reinstalling apps and reconfiguring settings, I wanted to perform a full backup of the phone's "initial state", just in case anything goes wrong. So, I went ahead and rebooted to recovery mode.

I'm using OrangeFox Recovery instead of TWRP (for those who don't know, it's based on TWRP but with more support for encrypted internal storage partitions, for my device at least). I started the backup process from there, only to find out some time later that it failed when copying the data partition, and a status code at the end of the message screen that did not make that much sense. Pulling the log file using adb pull revealed that the copy process failed to add a file from a subdirectory in the /data/misc folder.

I:Error adding file '/data/misc/9i0eBx6h5AsCJUBmui5L4C/ADq3lG3ELF4NPOElzFdltC' to '/sdcard1/Fox/BACKUPS/...../data.ext4.win000'

A Google search did not come up with anything, only about specific files and subdirectories in the /data/misc folder.

So my questions are:

  • What is the /data/misc folder (especially the random named subdirectories) used for?
  • Since I cannot get the backup process complete at all because of this single error, is there a way to bypass or delete the file? (if it's not an important system file)
na-no.

  • Does this answer your question? copy encrypted internal storage to pc ( in twrp mode ) – alecxs Feb 01 '22 at 19:18
  • @alecxs No, as I mentioned the OrangeFox backup situation just for context. My main question is about the /data/misc folder, as I stated above. – na-no. Feb 01 '22 at 19:57
  • /data/misc/keystore /data/misc/keychain /data/misc/sms /data/misc/textclassifier /data/misc/wifi /data/misc/profiles are valid subdirectories, does one of these exist? – alecxs Feb 01 '22 at 23:56

    @alecxs I can see the contents of /sdcard from OrangeFox with no issues, but the subdirectories you mentioned in /data/misc are nowhere to be found, only the jumbled mess. So, the directory is encrypted. I'll forward this to the OrangeFox team. Thanks for your time! – na-no. Feb 02 '22 at 10:31
