I have successfully upgraded my Ideos X5 U8800 to 2.3.5 official Gingerbread, rooted it, and then repartitioned it using Blepart recovery. Subsequently I have checked out cm11 source, including Blefish repositories/code for the U8800 (thanks for good work, by the way!), compiled/built and installed a ROM. This was my first build.
OK. Good so far. Only I am looking to build cm10.1 because my goal is to eventually get this handset running Ubuntu Touch. Therefore, the next step is to get it running on cm10.1.
My problem is that I cannot find the source I need. I have tried to set up a fresh source tree and check out cm10.1 source combined with Blefish's source by specifying branch cm10.1 for the latter, using the files I used in .repo/local_manifests to get the cm11 device source etc. from Blefish. However, something seems to be missing as the lunch command fails and compilation aborts. Also, I can see that development has been discontinued on this branch for the U8800.
