Moving to a new device? Or just switching focus to Android N? Or just taking a break?

Moving to a new device? -> I do not own this device ;) I've Nexus 4. Not moving to a new device

Or just switching focus to Android N? -> Yes, the team will work on Android N when the final sources are released

Or just taking a break? -> No

I know of an older G3 ROM that will give you GSM, shoot me a PM if you want the info. as I don't want to name it in this thread out of respect.

I love this rom but an issue for me that I don't have any mobile networking, I have tried to flash GSM patch for a couple time but it's nothing happened. When I flashed the GSM patch the com.android.phone is no longer working when I try to confirm my carrier. Can someone help me please!!!

off the coast o the kontiki!
Been awhile, but I was scanning through ls990 on AndrodFileHost & came across this rom & decided to flash it. I don't remember running this before but there I am on page 1 sharing svreenshots. Been running RR 7.1.2 for awhile but just felt like flashing something different. This is running great so far. Blast from the past

    • What is XOSP and how was it born?
    XOSP basically which stands for the Xperia Open Source Project was a project originally created by me for the Galaxy S+ (my old device) and the project was created like 2 years ago when that time XOSP wasn't even existing. It was just S+ Reborn. The main idea was to create a custom minimal Xperia based ROM, by including the essential things which a user would normal use from a ROM.
    The S+ Reborn became to be a big success because it was eventually ported on different Xperia Phones and some other Samsung devices and from there the XOSP project was founded. From the XOSP Project also the Reborn addons were created featuring with an Aroma Installer. I worked on the project for 2 years by trying always to improve it constantly, eventually for the fact that LP on my Galaxy S+ became to be quite buggy i decided to stop the development and for about half of year the project was left in stanby till i decided to bring it back again on the Zenfone 2 devices. The ROM will now also feature a White Indigo theme for all the ROM (framework, Settings and so on) and of course the newest Xperia Applications ported from the SystemDumps provided by the Sony community.
    The project started growing again so with the Release 4 the project will be completely refactored to XOSP.

    I have been flashing custom ROMs for a while but this has to be one of the better ones that I have come across! The install made me delete data (tried to cheat) which I did and was surprised at how snappy the phone was from the very beginning. In my trials to date the only app that is acting up (fc) is lol the Giant Eagle app! There app always has been kind of flaky so that is no surprise. Checked U-tube and Netflix, both are working fine, made phone calls, sent text messages and synched with my BT smart watch again without issue! I was also able to use BT to initiate the Google setup on the phone and have had no problems with the WiFi. I do not get 4G/LTE data so can not comment on those but otherwise this ROM has become my daily driver right out of the gate! The one thing I will need to keep an eye on is the battery but to this point it doesn't seem to be a significant problem. Thanks to the dev and keep up the good work!

    Edit: Spoke a little too soon... I did have a BT share fc but it was correctable with little issue.
    for some reason my google contacts don't sync

    Not happening for me. I clean wiped with Banks Gapps.

    A side note though, everything works really well so far that I have tested.
    2 very minor issues - the boot animation/shutdown animation is really small so you can barely see it on the screen. Second is the status bar says Domestic Roaming. I believe this gerrit is what is needed to fix it.
