On certain SCP-XXXX, (let's just say you've tried the memory locations without any luck) use CDMA Workshop v2.7.0, connect your phone and navigate to the Security tab. Under the SPC box, select "Universal, EFS Method" and you under the NVM file select "nvm/nvm/nvm_0002." If you get an EFS Read error then this method will not work. If you do not get your SPC from nvm/nvm/nvm_0002 then go down the list of all available options within the EFS method. I've only done this method a handful of times on 3200's, 3800's, and 3810's after the memory addresses have failed to retrieve the SPC. So far this procedure works about 80% of the time for me. Note: This procedure should be treated as a last-ditch effort to obtain the SPC if all else has failed. It tends to run very low success rate with the 2700's.

Due to lack of Sanyo phone I see and flash, I really would like to get this method verified by a few other people. Thanks.
