Hiya there.
Im kinda new here in this forum so greet me well . ^^
Well I juz finished searching and figured out . I would like to share how to combine multiple mmssms.db (Message Data) file into one file where the file located on /data/data/

So what we gonna need is these 2 file .

*[TOOL] yaffs extractor, mmssms.db & contacts2.db converter
*SMS Backup & Restore

1. Extract yaffs extractor, mmssms.db & contacts2.db converter to you main drive. (Like mine ish C:\ )

So theres the file that you extracted located open it up and see wether all the file extracted is same as in the pic.

2. Next we have to put the *.db file in the yaffs extractor, mmssms.db & contacts2.db converter folder,I have 2 backup *.db so I made 2 folder(Message1 and Message2) which is each mmssms.db file in each folder.

3. So now were gonna convert the *.db file into *.xml .
Run cmd and put this command . (Convert all your backup *.db cause we gonna need it , depends how many you have )


cd c:\yaffs-mmssmsdb-calls-extractor

extract -s Message1\mmssms.db


Juz put anyname you like as long you put .xml along with the name .

And the converted file will be in the same folder yaffs extractor, mmssms.db & contacts2.db converter in the *.xml format . We gonna need those files soon just let it there .Now we're almost done , going to next step.

Next, install SMS Backup & Restore on your phone . Put all converted *.xml file in the /sdcard/SMSBackupRestore/

Now open up SMS Backup&Restore that you have install on your sdcard.

Wait till the Apps pop out and Click on Restore , you will see the *.xml file that you have copied to the /sdcard/SMSBackupRestore/ .

Now, Click on each of *.xml and restore every single of your backup message file.

And the Results ..

The Failed might be due to corrupted or unread message while backup.
Thats it ! You're done, you have merged all of you mmssms.db into one file.
Goodluck on trying , glad to help and share. ^^

Thanks a million

This is really a lifesaver,
The screen of my phone died, so all I had access to was adb and through this guide I was able to restore messages.
I did not have to merge, but it worked the same.

Thanks once again

Worked like a charm! I've been different methods all week, trying to copy the old mmssms.db to the database directory, and everything failed. But not this!

Tank you!

so what if we want to merge multiple contacts2.db? is it the same way? i am pretty sure it's not, the command would be different right?

Does this merge MMS messages as well? Or does it only merge SMS text messages?

I know SMS Backup & Restore typically doesn't restore MMS so I'm thinking this method won't work for MMS.
