I'm looking for advice/pointers on a project.
I have 150 XOOM tablets (wingray) that our school received in 2011 as part of a technology grant. They are on 4.1.2 and the staff have stopped using them because they lag and don't support a lot of current web-based content. My role is that I'm a former board of education member and I have experience flashing. The superintendent and I are talking about trying to upgrade the tablets with a CM or Lineage-based ROM and replace batteries where needed.
I have been looking at Lineage 13.0 as it appears someone started the process there but I don't seem to see any discussion or progress. I saw there was a MM ROM that @Schischu was working on, but all the binaries were on a server that is no longer operating (duckbox). I see a thread started this week with a 4.4.4 build by @Manuellama but that's not exactly recent. But, it's better than 4.1.2.
I don't mind going through the bigPart process. I did this several years ago on my personal wingray and CM 11.0 runs fine on it. I'm not sure about doing this on 150 devices though. I'm sure I'll lose a few of them to failures in partitioning, but it's probably worth the risk.
I would like a ROM that I can build. I have some experience with this, but I'm not a pro at customizing the experience. I would like a couple apps used by the district to get into the ROM as well as a custom gApps package. I'd like to replace the boot animation to use our school imagery. I know space on /system is tight. Some gApps aren't necessary (Play games, Play music, Hangouts) while others are (Docs, Sheets, Drive). Also, the standard ROM builds I've seen tend to include apps like Apollo, QuickOffice and Movie Studio, which aren't necessary for our use case.
I'm looking for ideas on how to keep this project from going completely overboard. It's one thing to have one or two devices, but it's another when there are 150 devices.
