Hi, I'm having lots of gps disconnection during navigation with maps since firmware change and update, do you have same issues?

I also noticed an increased drain of battery (not too extreme).

Hi guys, I'm having an issue with the play store.
I cannot install or update apps any more. I don't know if it's a problem with the rom.
I just wanted to know if someone else has the same issue.

can someone here please give me some feedback on the development status of Omni for chiron? I just got my mix 2 the other week and playing with different ROMs; i noticed this thread was very active earlier but has somewhat fizzled out -- are you folks still using this rom, is it being maintained/updated etc?

Does anyone know if they ended the development of this rom? The last version listed on their website is 2 months old.

Hello all,

I've an MI MIX 2 rooted with Magisk and latest OmniROM. I've seen that 'equaliser' is installed by default, but I'd prefer to use Viper4Android. Should I 'delete' equaliser first, before installing Viper4Android ? If so, how can I do that ? (On other CUSTOM ROMS it's necessary to do that).

Viper thanks in advance !

    New builld (READ NOTE!!!): omni-8.1.0-20180420-chiron-HOMEMADE
    Download: https://www.androidfilehost.com/?fid=890129502657598901

    So historically from Oreo Bringup, we used for chiron the wrong encryption in previos builds of all custom ROMs.
    Also official lineage will use new-one. And we all need to move to working one. BUT for this you need to make few steps
    include FULL WIPE WITH FORMAT. All new roms will not work without it. (As old roms will not work with it).
    ABOUT Official WEEKLY Omni: You need to make full wipe and do this step for 04/23 build!!! No OTA for this build!!!
    So this is migrate to new ROM with new encryption:
    1. Backup your apps with TB (optional)
    2. Backup all data you need from Internal Storage to PC/USB OTG
    3. Install this TWRP and reboot recovery: https://build.twrp.me/twrp-3.2.1-0-chiron.img mirror: https://www.androidfilehost.com/?fid=890129502657598900
    4. Format data in TWRP - WARNING! This will delete all from ur Internal Storage
    5. Wipe all
    6. Install only new ROM and reboot.
    7. You will see errors when rom start (optional).
    8. Reboot to recovery and make 3,4,5 pt again.
    9. ROM must boot without errors. Flash what u want, restore internal storage, restore from TB. Dont restore from old TWRP backup!!!
    Now you can use new roms (with encryption). No need to to this every time! Next flash/update to rom that support encryption as usual.
    Older ROM will not work, to make work rom without encryption you need to do same as in 1-8, but new rom will not work.
    NOTE2: If u use MAGISK, please flash it after reboot to ROM!!!

    ChangeLog (thats all result of teamwork, big thanks to Vol Zhdanov):
    * Fixed encryption, move to ICE
    * Kernel update to 4.4.128
    * VoLTE fixed (? need test)
    * Big init cleanup, tweek & fix
    * Many vendor fixes
    * Fully commonized with Sagit
    * Sync important changes with LOS
