DO NOT USE THIS NANDROID IF YOU TOOK THE V7 (ICS) UPDATE. YOU WILL HAVE NO DATA CONNECTION. YOU HAVE BEEN WARNED.
Ok, so because this has been asked for a few times, and I had spare time, here is how to return to pure, fresh out of the box, V4 or V6 firmware stock using just a few files and CWM Recovery. Now this will have no root, no CWM Recovery, no anything that you may have put on here once you are done.
First:
Make sure you have CWM Touch Recovery installed. The first one that was released (non-touch based) does not handle nandroid backups correctly.
Then grab these files based on which version you want to restore and follow the corresponding instructions.
DO NOT MIX AND MATCH VERSIONS. YOU WILL NOT BE ABLE TO TAKE OTA UPDATES PROPERLY IF YOU MIX V6 NANDROID WITH V4 RECOVERY RESTORER
V4:
http://androidfiles.massivefilehost.com/v4_stock/stock_recovery_restorer.zip
http://androidfiles.massivefilehost.com/v4_stock/v4_stock.zip
Extract the contents of v4_stock.zip to the sd card of your phone so that the directory inside of your zip is at /sdcard/clockworkmod/backup/v4_stock/ . If you do it wrong and put it at /sdcard/clockworkmod/backup/v4_stock/v4_stock/ it will not work.
Copy stock_recovery_restorer.zip to the base directory of your sdcard so the end result should be /sdcard/stock_recovery_restorer.zip
Next :
Now boot into recovery.
Make one final nandroid backup if you are so inclined.
Now at the root menu of CWM Recovery choose wipe data/factory reset , then yes.
Then go into advanced -> Wipe Dalvik Cache -> yes
and also advanced -> Wipe Battery Stats -> yes
Now go into backup and restore -> restore -> v4_stock
If it goes correctly, proceed to the next step. If it fails, you placed the files incorrectly. Reboot your phone and fix where you extracted v4_stock.zip to.
If all went well, go to install zip from sdcard -> choose zip from sdcard -> stock_recovery_restorer.zip -> yes.
V6:
http://androidfiles.massivefilehost.com/v6_stock_noroot/stock_recovery_restorer_v6.zip
http://androidfiles.massivefilehost.com/v6_stock_noroot/v6_stock_noroot.zip
Extract the contents of v6_stock_noroot.zip to the sd card of your phone so that the directory inside of your zip is at /sdcard/clockworkmod/backup/v6_stock_noroot/ . If you do it wrong and put it at /sdcard/clockworkmod/backup/v6_stock_noroot/v6_stock_noroot/ it will not work.
Copy stock_recovery_restorer.zip to the base directory of your sdcard so the end result should be /sdcard/stock_recovery_restorer_v6.zip
Next :
Now boot into recovery.

Now at the root menu of CWM Recovery choose wipe data/factory reset , then yes.
Then go into advanced -> Wipe Dalvik Cache -> yes

If it goes correctly, proceed to the next step. If it fails, you placed the files incorrectly. Reboot your phone and fix where you extracted v6_stock_noroot.zip to.
If all went well, go to install zip from sdcard -> choose zip from sdcard -> stock_recovery_restorer_v6.zip -> yes.
Final for both:
You are now back at pure stock with no data. Reboot your phone and it will be like nothing was every installed.
As always, let me know if you run into any issues not covered in the instructions.
