[sirtronics]

My TP in running CM9 very nicely but I had installed about 3 other Andriod builds BEFORE cm9.
not when I boot it have have a lot of choice (all of the other Andriod Roms, Plus CM9 Plus Webos)
how can I clean this out or is there a way to just wipe all of the others and start fresh.

thanks!

If you used ACME installer, then you need ACME Uninstaller.
