I have a sd card (Is this a requirement when rooting and romming?) and I have 11.35 gb of internal available space .
Ok, great. That should be plenty for one ROM slot, even for two or three, if that's what you really want to do.
To install Minimoto:
- As I said before, copy the minimoto zip file to internal storage or the SD card. It can be in a folder if you wish. Do not unzip the file.
- Power off the phone down
- Turn the phone on. When you see the Safetrap screen, press the menu key. This should start Safestrap recovery. If it does not - sometimes it doesn't, and the phone just boots normally - power off the phone, slide open the keybaord, and power on while holding down the "M" key. A white text menu will open - use the VolDn key to scroll down to "BP Tools" and then press VolUp to select it. This will also start Safestrap
- At the Safestrap menu, which is a series of boxes with text, select "Backup". You can choose "cache" if you want, and choose ".android_secure" it is more than 0 MB. Choose whether you want the backup stored on external SD or internal storage at the bottom. Slide the "swipe to backup" at the bottom to backup. This should take a few minutes. When it is done, hit the "Back", and the the "Home" control in the lower left of the display.
- Hit "Boot options"
- Hit "ROM-Slot-2" (I suggest saving ROM-Slot-1. The Cyanogen/AOKP builds that run ICS and JB for now run only in ROM-Slot-1.)
- It will ask to create a data partition size. The Droid 3 stock phone has a 2 GB data partition. If you install a lot of apps, that's probably a good choice. If you have hardly any apps, maybe 1 GB is good enough.
- After choosing the data partition size, hit the button "Create ROM slot" at the bottom. This will take a few minutes - longer than the backup.
- This will bring you back to the slot selection screen again. You'll notice that at the top it now says "ROM Slot: rom-slot-2". This is what safestrap will boot on the next boot. Now we need to flash Minimoto. Hit the "Home" icon on the bottom left of the display. (Actually, the home capacitive button works, too.)
- Because this is a new ROM slot which was never installed, there is not data to wipe. However, if you ever install another ROM in this slot, you would go to the "Wipe" button, then "Factory reset". It won't hurt to do this. It will ask you to "swipe to wipe" at the bottom. (Do not wipe "External storage" or "Internal storage" unless you want to lose all of your photos, etc., and ROM slots.) Hit home when done.
- Hit "Install"
- Navigate to where the Minimoto zip file is and tap the file name.
- At the next screen, swipe to confirm flash
- As long as there are no errors, hit the button "Reboot system"
- (If there are errors, go home. Tap "Boot options". Tap "Stock ROM". Tap "Activate". Tap home. Tap "Reboot". Tap either "System" or "Power off" - you'll go back to stock.)
Otherwise, you'll be asked to setup Minimoto after boot. You'll also notice when you see the Safestrap screen at boot that it is now "Enabled".
Let me know how this works/if you get any errors...
