Salvaging Baytrail/Android tablets

Salvaging Baytrail/Android tablets

A few years ago I suggested a non-profit I work for purchase 30 Intel "branded" Baytrail tablets that were built by ECS ( This turned out to be a really bad decision as neither Intel nor ECS want anything to do with supporting them, never have. Since the day I bought them I got the "call Intel / call ECS" dance. Super lame.

The tablets run Android 4.2.2 (3.4.34 kernel, build number 40105-0017.00.01.01)
The tablets are ECS TA70CA2

All of the apps we use to take donations, etc have upgraded for various security reasons and these tablets are becoming boat anchors. The hardware is good. The total lack of software support is the problem.
I need to flash these tablets with something more recent. I have seen 4.4.2 images on but they aren't in the format I need. ECS did tell me I needed to use the Intel Phone Flash Tool to update them. Funny since they wouldn't give me a newer OS version to flash them with.
Since all ECS did was take Intel's Baytrail tablet reference spec and build it, is there any way I can compile my own version of KitKat, Lollipop or newer?
Right now I have an original 4.2.2 flash package from ECS and its a zip file ( that contains:


Under the hood it's all Linux, especially in this case IA Linux. I'm sure those bin files are some shims of some kind for the platform.
I'm trying to rejuvenate these tablets, remember non-profit, and I'm hoping someone can suggest how to create a newer OS load for these tablets that use the Intel PhoneFlashTool to download it to the tablets.
