Like every developer says:
I AM NOT HELD RESPONSIBLE FOR ANYTHING THAT HAPPENS TO YOUR DEVICE!
What is FFW?
FFW is a script written in batch that will automatically wipe your phone, leaving no traces of the past install.
I'll pretty much sum it up like this, it erases the boot, system, userdata, cache, webtop, preinstall, and reboots the phone.
There are two versions, Fastboot & Moto-Fastboot, I don't know the difference but I made a script for each version. The whole package is there, just download, extract, and run the batch file!
1. Download any of the two versions.
2. Boot into recovery.
3. Wipe the Dalvik cache.
4. Wipe the cache.
5. Factory reset/data your phone.
6. Boot into fastboot.
7. Run the script.
8. Your done!
You can now install any ROM you choose! Be carefull for hard/soft bricks, installing the wrong ROM can ruin your phone!
