[Moto G 4G Android Development] pok1yoyo:
Hi,

What I meant was that I built it myself, not using the prebuilt image available at #332.

I have followed your build instructions, the only thing I had to change was I have removed the `extern` from `kernel/motorola/msm8226/scripts/dtc/dtc-lexer.lex:42`, because the compiler was complaining (previous declaration of 'yylloc' was here). After this change, the build succeeded.

My current build also has microG patch for signature spoofing, but I think this has happened even without the patch.

Edit: I have also manually formatted the /data partition to ext4 and shrunk it for a few bytes, because TWRP's data format is broken and it doesn't allow encryption, though I don't think this has any effect on the aforementioned issue.

Edit2: Here is the result of the repo diff:
