I have several android tablets which have crashed and not going to the boot up / reset options. Anyone know if there is an easy way to get another operating system on an android ? Example when my XP operating system died, I was able to put ubuntu on the hard drive and write over the broken system - and its still working fine now. I've looked in various forums and they all presume a person understands codes & commands and stuff - I don't, an android is like a mini PC I would have thought, just needs a new operating system installed!
