RIL is now working (it requires more testing though). So far calls and SMS works fine. Mobile data also works, i wasn't able to connect to the LTE network of my provider though.

SMS app crashes when opening the keyboard on a chat.

Right now, i won't share this build because, for some reason, boot time increased a lot. I'm not sure at all why this is happening, but until it doesn't gets fixed, i won't publish it.

correcting the bug of the Minecraft arose the problem that the time of ignition increased considerably? I will wait for the new update to install it

Edit: And if for the bug of the message application you try to use the one of Google, the one in the GPlay, as a replacement? that one suggestion :good:

I'm sorry for my English, I use GTranslate.

Maybe the booting time its not a problem even though it reach 10-20mins since some of rom booting just like that

Finally got Lineage OS 14.1 for Galaxy J2lte

You're really working hard bro
Thank You for bringing AOSP rom for our device

It's a problem because it's every boot, not the first one. Sometimes it feels like it won't boot, so i try to reboot the device until it does. Seems like reinserting the battery helps sometimes.

The boot problem? It only seems to happen on reboots, but after i accidentally odexed the ROM, the problem weirdly happens.
