Default [Q] Blank Screen when Restoring Stock Backup from CWM

Hi,
following the instructions on cyanogenmod.org, I have flashed CWM (using heimdall), then made a cwm backup of the stock rom, then installed CM10.1.3 stable. Works great.

Now I'm trying to restore my stock backup temporarily because I forgot to export my address book and my text messages (stupid me, I know). Of course, I have made a cwm backup of my CM first.

I wipe everything (factory reset in cwm), then restore my stock backup in cwm, and it goes through smoothly. However, when I reboot, after the Samsung logo there's the boot sound, and the screen goes blank completely. Nothing happens after that.

I can reboot (hold down power button forever), go back to cwm, and restore my CM backup, and everything works perfectly again. But I can't get my stock backup to work.

Can anyone help? Or is there a way to find the address book or text messages in the cwm backup files manually?
Thanks!

You mean Android version? I believe stock was 4.04 (official OTA update quiet some time ago), the cwm Version is 6.06, I think. And CM10.1is Android 4.1.

Best thing you can to get it running is flash stock with Odin and forget about 4.0.4 nandroid. You see the 4.0.4 firmware has a bug which may brick you're phone. Don't factory reset whatever you do. Can you not mount as USB is recovery and get the data that way.?

Sorry, I just checked again, cwm is this, so JB 6.0.2.9:

http://cmw.cmfs.me/c1/recovery/GT-I9...ry_6.0.2.9.tar

Regarding Android stock version, I'm not sure if it's 4.0.4 or 4.1.

I can access the nand backup easily, it is on the external SD - is it possible to get the address book out of the nand directly?
Thanks so much...

I'd concentrate on getting the phone up and running first as once you have a working phone, the options for recovering ur data get that much easier......example....I believe you can use titanium backup to retrieve data from nandroids.......
And as @andrewwright says.....stay away from 4.0.4

This might be my S2, or it might be my W...but it's definitely CM

Got it. What I did was

0) Make a complete cwm nandroid backup.

1) Restore only the /data partition of my old cwm nandroid backup using cwm, then stay in cwm recovery and copy my old contacts database to my computer:
Code:
adb pull /data/data/com.android.providers.contacts/databases/contacts2.db
2) Use the dump-contacts2db script from the awesome project at https://github.com/stachre/dump-contacts2db to dump a vcf file from contacts2.db.

3) Restore the cwm nandroid backup made in 0).

4) Copy the vcf file to my phone and import it in contacts.

I found awesome advice here: http://android.stackexchange.com/que...nandroid-image
