Hi! Anyone have any internet connection problem using mobile data?
Is always disconnecting using LTE or 3G for a moment, and after some seconds it comes back. The connection is not consistent at all in every location I have tested.
I'm using Spanish mobile frequencies: LTE/WCDMA/GSM.

    Hello everyone, finally.
    Mi9 has been officially supported again, this time from another developer, a developer that I know will provide the best for the device, you can check an official site for the roms files.
    I was very happy to be with you, thanks for everything and every word. See you in another work
    The update has been pushed, please do clean flash and Enjoy.
    Hello everyone, I am very happy that my labor did not go in vain and that you are commended. The reason why the mobile internet does not work at the first setup is that you have to manually activate the APN, however this problem has been solved and I will upload a small file once it is flashed, which will solve the problem. As for the problem of not being able to activate the Wi-Fi, this is not a problem just a glitch that happened to me once in the trial phase and did not happen to me again and I guess that it did not happen with the majority, if it happened with you, just click on setup Offline and when you finish from the first install list, you can Activate Wi-Fi easily (you will not face such a problem if you flash the APN Repair file).
    ~As for the battery performance, I am satisfied with it and see it in the list of the best ROMs in terms of battery life for Android 11 on cepheus.
    ~I have created a channel on Telegram to chat about ROM or report bugs, this is Pixel Experience chat for Cepheus. https://t.me/pixel_lamjiidii1_mi9

    After flashed it
    go to Settings - System - Advanced - Reset options - Rest Wi-Fi,mobile & Bluetooth and chose your SIM then click Rest settings.
