    Ok so I found in /proc/ a file called omap_dev_type with the HS value in it but whenever I go to edit it to NS the changes dont keep meaning either I dont have the permissions for it or the OS is reverting it after saving it. I think its possible.if.we can change this value then update via normal update it might just do it. Thoughts?

    another thought. right now, updates can only be installed if they are signed by moto, right? what/how is it signed? how does the phone know if it is signed by moto or not?

    the unlocked bootloader is signed by moto, the recovery checks for the signature when it boots into an update process. The bootloader i am talking about is from moto, its in the update packages. also i have tried editing the updates but it does a md5 checksum too, so if you edit anything they will not attempt to update. really the only option that i can see is tricking the phone into thinking its a dev phone because everything else is signed by moto and has to be checked for security too. we have to trick the phone into flashing the included bootloader. thats the only way i see it happening.

    Root explorer and most file managers only change /system to read write you would have to do it in terminal I believe. Or adb

    Its not even a permissions thing. /proc is a read only virtual file system. It has to be.written in a completely different manner ill post soon if I can get some success.

    my thinking was that if we could find a way to duplicate the moto signature then we could create a rom and add the moto sig. I dont know if at all possible but i figure its atleast worth a thought

    You are talking about high level encryption. If we could "sign" updates we would not need an unlocked bootloader. You are talking about something that the best hackers cannot do. Exceptions being geohot and the ps3 and thats because sony screwed up.

    With the OS up and running it did not work. Maybe while in recovery?
