I remind you that if you have the bug that some apps do not recognize the SD, follow the link for the fix that is in the first post of TBM

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

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.

    Hello Mr. tmb 13
    I am really happy that such people can be found to develop such an operating system!
    I'm very happy to find this page because I usually do not find a good custom ROM for this phone
    I have a few questions for your service
    I have a 2015 j2 j200f phone
    1- Will this custom ROM be installed on this phone?

    2- What are the problems? This phone has two SIM cards

    3- Is it still being developed?

    4- How should I flash this custom ROM with GNU / Linux?


    This phone of mine is out of date and now its screen is broken. Your custom ROM is the only way for it to be worth repairing again.
    Anyway, I want to take the phone I want out of you, even if it is necessary to heat the sink and fan!
    :)
    1- Yes, it will.
    2- The problems should be the ones listed in the thread. Last update broke SIM detection on Dual SIM devices but this should be fixed by flashing the boot image available here.
    3- This is no longer under active development as my device broke a long time ago, but thanks to Ciyanogen's contributions the latest build is relatively new.
    4- The only thing that changes in the process is how you flash TWRP, you should be able to find some guides on internet.

    New update available. The apps crash problem is now fixed and the Android Security Patch was updated to October 5, 2019.

    I wanted to release this update yesterday, but i wasn't able to do it because my Ubuntu installation almost broke when i was upgrading to the latest version. Luckily, i managed to restore it.
