Hi guys
It's me Jose (jmpfbmx)
I have registered today and I hope that i can help you doing UT

The sources where i am developing and used for building LineageOS15.1 for M10HD are these:

• Device tree: https://github.com/bq-mtk/android_device_bq_freezerhd
• Kernel source: https://github.com/bq-mtk/android_kernel_bq_freezerhd
• Vendor blobs: https://github.com/bq-mtk/android_vendor_bq_freezerhd

As the ODM that bq used didn't provide connectivity modules, the fix I gave was using prebuilt modules from Stock Oreo ROM, i am not sure if that will work at Ubuntu Touch

Thanks
Regards Jose
