Hi All,

First and foremost, *awesome* work :-)

I have been searching for getting Linux on MT 6235 after I happen to
get this phone in India

I think it is based on MT 6235, as when I connect it using the USB
cable to a Windows box and select the camera mode it identifies the
camera as MT 6235. Reading in a document I found online (one question
here, can I paste the link to the source which I found online, it is a
confidential MTK presentation), it states that MT 6235 can only
support up to 2MP camera and it states that MT 6238 can support upto
3MP, the phone manual says 3.2MP.

Pardon my ignorance, but what would be the best way (source to read,
experiment and create serial cable) to replicate the work you guys are
doing with this phone. I tried the MTK flashtool but it fails, though
it detects the phone as MT 6229.
