Complete guide to getting the Square Register App on the Droid X
1. On your computer, download both the sbf file you’re wanting to flash (extract the .sbf file if it’s zipped. Found here: https://sites.google.com/site/motosbf/droid-x-sbf-files), and the sbf_flash program. You can get the latest version of sbf_flash at http://blog.opticaldelusion.org
2. Open a terminal in the directory where you have the sbf file and sbf_flash program. Type “chmod +x sbf_flash”. This will make the sbf_flash file executable.
3-5. Hold Camera + Volume Down + tap Power to bring up the bootloader.
6. Plug your phone into the computer using the usb cord. Wait a few seconds to allow your computer to recognize the device.
7. In the terminal (still opened in the same directory as the sbf_flash program and the .sbf file), type “sudo ./sbf_flash nameOfSbfFile.sbf” (obviously you’re going to want to change the last part to the actual name of the sbf file you have on your computer) and enter your password when prompted.
Edit: Thanks to balltongue for providing the info on the correct command for running the sbf_flash program on OSX. For OSX, substitute “sudo ./sbf_flash nameOfSbfFile.sbf” with “sh ./sbf_flash nameOfSbfFile.sbf” instead. The rest of the tutorial should work as written.
8. Allow the program to work. It’ll take several minutes and your phone will reboot at the end.
*** If the phone boot loops: ***
Remove the battery. Insert battery again and turn the phone on using the Power Button and the Volume Down button again. This time, press the Volume Down button until you get to “Android Recovery”. Press the Volume Up button to select it. Press BOTH volume keys once you see the exclamation point in the triangle. Select the “wipe data/factory reset” option with the Volume Down button and initiate it by pressing the Power Button.
Reboot your phone and you should be all done.
