Worked for me! Thanks.

I have a rooted phone with a custom rom (CyanogenMod 6.1.1). Rather than buying Root Manager from the Market, I booted into Recovery and backed up the efs file. This means a copy of the Tar file is created in the Samdroid folder on SD card. I copied this onto my PC. I kept a clean copy (in case of problems), and edited a second copy using 7-zip to open it up. Then I clicked on the bin file. I was asked which file to use to open it and I clicked on the hex editor to associate the hex editor (I used XVI32) with the bin file. I made the two changes suggested by Seraser in the first post, and saved it.

Then I just copied the revised TAR file back to the Samdroid folder on the phone micro SD card. I booted into recovery and selected recovery and chose the TAR file. Now my phone is unlocked.

I tried to copy nv_data.bin by doing:
adb shell
remount rw
del /efs/nv_data.bin
adb push nv_data.bin /efs/nv_data.bin

The phone restarted and now i cannot even boot it up... and restoring a /efs backup takes forever: Never ends formatting+restoring /efs... did i soft-brick my spica?
In such case... how to fix it?

Try with Odin, with clear efs option, then mount this partition and restore your nv_data.bin.

The problem came from formatting the /efs partition before restoring the backup.... never EVER format it.... just do a simple restore.......

I changed my SGS+ for another Spica.... my wife's...... waiting for the LG Optimus 2x to come

Thanks for the info, however after checking several tutorials and howtos I still have an unanswered question about unlocking and upgrading a Samsung Galaxy Spica i5700.
I’ve just got a Spica locked by Orange with firmware 1.5. I’m planning to first unlock and then flash it with Eclair and if possible with Gingerbread.

Unlock:
Following your guide. This process requires the Spica to be rooted, so the /efs/nv_data.bin can be edited, right?

Rooting:
