A few notes before you proceed:
  • Before going straight to the downloading, there’s something we would like to tell you. We have changed the default encryption method for the phone, migrating to File-Based Encryption (you can get more information from the official Google documentation page). In order to get this encryption mode working, you will need to use our custom recovery (compiled from the latest source) which is compatible with this encryption and, just for the first time, you will have to wipe your internal data, so backup your data before proceeding.

Installation Instructions:

  • Grab our recovery and install it.
    Through TWRP Recovery:
    Install Zip > Install Image > Choose ‘recovery.img‘ > Select partition ‘Recovery’ > Swipe to confirm flash
    Through Fastboot:
    Code:
    fastboot flash recovery recovery.img

  • Install the ROM and then wipe your internal data partition.
    Through TWRP Recovery:
    Wipe > Format data
    Through Fastboot:
    Code:
    fastboot -w

  • Reboot into system and wait until the process finishes, it could take a little bit. After the installation is done, I suggest waiting before using the phone because it usually goes into thermal throttling after installing a ROM.

Installed it with no issues and so far so good. It's a complete rom, has everything i need even gray scale reading mode. Didn't notice any battery drain for now, but still i always enable agrressive sleep and standby. Will give any further thoughts after i used it for a while. The onyl thing is that the simple gapps do not work on this rom, had to use open gapps.

Oke so my review in short. The rom is as most roms just fine. For my usage i have no bugs to report. The only slight potential donwside might be that the battery life was not as good as on pixy or superior os, but its not far behind. However this might be due to, I've used a lot more lte with this rom than on those since I'm back to work form vacation, and second that my battery might be giving me slight signs it'll need a replacement soon. So take the battery thing with a grain of salt, try it your self first and compare.

Hi, thanks for the ROM, runs great from the short time I had on it (forgot to get gapps package) when I got opengapps 9.0 stock it said that the ROM needed opengapps for 8.1, same with Pico, pretty confusing. Any help would be great

Gapps issue

I even tried Simple Gapps, thinking maybe they would work. Will try 8.1, but it definitely won't use 9.0 gapps. BTW, I downloaded the nano gapps. Other than that, this rom is absolutely beautiful. It is fast, and it is just a very good-looking rom. So, I hope you keep working on this. I can't say enough about how quick it is. So, thanks, and I hope the gapp thing can be worked out. Okay, what ended up working was ARM 8.1 gapps. NOT arm 64. Not sure why or how. Just FYI. Thanks.

    Is this system-as-root? I'm BLOD and patch won't work if it is!
    This is system-as-root
    we made a build for 4core devices with the patch but there few features which don't work.
    I'll be building EvolutionX in few days.
    I'll try not to make it SAR so that you can flash the blod patch :)
