I was using Nexus S i9020T, CM7 nightly (a few weeks old) and for some reason I wake up this morning and couldn't get past the CM7 "blue circle" screen booting. I had about a month old backup but I didn't want to lose any recent data so I made a Nandroid backup.

Normally, to restore SMS or MMS from an old backup, one can just restore the nandroid backup, use a third party SMS backup program to backup the data to sdcard or gmail, restore or install new rom, then restore the SMS from the third party backup software.

However, in my case, I had a nandroid with data on it that I wanted to keep but that wouldn't boot.

So I did some searching and others have had this problem before but I figured I'd put it here for others that may have the same problem. I am not taking credit for this I just found various pieces of info around the web.

The solution is to use a utility called unyaffs. Unyaffs will need cygwin.dll. Yaffs is the file system that CWM recovery nandroid backups are stored in. Windows cannot read or mount this file system AFAIK.

Instead of compiling unyaffs for windows and installing all of cygwin, just use the attached pre-compiled unyaffs.exe and cygwin.dll.

Here's the process:

To restore SMS/MMS from a nandroid backup using MS Windows:
  1. place unyaffs.exe + cygwin.dll + data.img in a folder
  2. open command prompt in this directory (shift+right click -> open comand window here)
  3. type: unyaffs data.img
  4. the contents of the data.img will be extracted to this folder. wait for extraction to complete
  5. browse to \data\com.android.providers.telephony\databases in the extracted folders
  6. copy mmssms.db, mmssms.db-shm, mmssms.db-wal to sdcard
  7. use root explorer to copy these three files to \data\data\com.android.providers.telephony\databas es

To restore contacts/call log from a nandroid backup:
  • repeat above process for \data\com.android.providers.contacts\databases

To restore launcher configuration (only for stock Gingerbread launcher):
  • repeat above process for \data\com.android.launcher\databases

Note: Be aware that replacing the existing files with those extracted from the backup will remove the existing data so if you're not 100% sure what you're doing, change the names to mmssms_OLD.db or otherwise back them up before pasting the files from the backup.

Edit: Just thought I'd add, I also came across an app called AppExtractor but, despite the good reviews, the SMS/MMS restore didn't work for me.

if you have titanium backup, it makes it a lot easier to restore specific items from Nandroid Backup

I'm on an SGS I9000 and made an SMS/MMS backup using titanium backup when I was on Gingerbread.
Now I've installed the "Onecosmic's ICS Port Android 4.0.3 RC3.1" and restoring the backup file using titanium (only data) makes my message app FC.

Jarmezrocks were you successful when restoring your SMS/MMS on ICS?


Does anyone knows how to restore them? From titanium backup I only have an *.apk.gz and *.properties files.

Thanks for any help.
Cheers

Great post. I wonder if there is a file extrator in Android like unyaffs?

I found out that you can restore SMS just by using Root Explorer.

The location is the same, just that the files are these ones:

mmssms.db
nwk_info.db
telephony.db

I tried and it worked only using RootExplorer and I extracted the files from data.ext4.rar

Does this need to be done using ADB? I have set a nandroid backup from a GB ROM and flashed ICS on the phone; however when I extract the data.img using unyaffs and browse to the mentioned directory, there are no db files whatsoever.

Could the nandroid backup be corrupted for some reason?

I am looking at the data\com.android.providers.contacts folder and I only see a lib folder with nothing on it.

Hidden system files are set to show BTW
