Flexing the L7If you already have an unlocked phone, it is highly recommended you download this file and flash it before flexing your phone for the first time! This file contains a subsidy reset flex which will set your subsidy unlock code to all zeros (00000000). Just in case you install a flex that does lock your phone, you can easily unlock it by entering this code.
There are a couple types of flexes at Mod My Moto. There is the "flex" (the original factory default one), and the "flexlash" (a flex which comes in a flash file format .shx). As with the flash file, just get the most recent flex you can. Once again, I'll cover flexing with RSD Lite. You could also use Flash & Backup to do this.
I'm going to use the "art2d2tx's Flex v2" in this example. Start RSD Lite and wait while it recognizes your phone. Click the button labeled "...". This will display the open file dialog box.
Now find where the flex is on your computer that you want to use, highlight it and click "Open".
Click the "Start" button. Now you should see what's displayed on the screen as the program does its thing.
This is what the phone will display during a flex:
After it's finished and your phone has given you a confirmation tone, you can click "Close" and disconnect your phone from the cable and check out your changes.
If you should get a message like this where the program seems to hang:
Don't panic. Just close the program, chance are your phone is just fine. Sometimes this happens.
I learned how to flex my first phone (a V3) from MotoX at his tutorial right here.
This ends the "flex" section of this tutorial.
