I recently acquired an Android-based tablet which is now running a rooted version 2.2; however, the manufacturer no longer supports or sells this particular tablet.
I'm interested in seeing if I can install Android 4.0 onto it by keeping the Linux kernel from 2.2 and just replacing everything else. Despite the GPL, the manufacturer never released any source code for their custom modifications so I can't, for example, compile a new kernel. So my basic plan is to replace the software stack with the stock Android 4.0, copy any custom applications over from 2.2 that came with the device, and see what happens.
Has anyone here tried anything like this before and can advise on any potential pitfalls before I go ahead and inadvertently brick my device? Thanks in advance!
