back in my Droid X2 days, and even as recently as on the Droid RAZR/Maxx, you could easily swap the position of your memory cards as to trick your phone into thinking your external/removable SD card was the primary memory. All this required was to reboot with bootstrap, and flash the file, and all was good.
I have the original old flash / .zip file but not sure if it will safely work with the RAZR M.

Further more, I can find a working bootstrap for the "M", and I tried "SafeStrap" but was unsuccessful as I did not want to create a whole new partition and flash a new rom. ( I am not really a fan of SafeStrap so far

)
Any input?
Thanks
