Follow the instructions, you're not supposed to wipe everything.
You need full firmware first, if you wiped system and then follow instructions

Now I'm a little confused. Starting from Xiaomi eu do I have to flash from flashtool the entire stock rom or is the flash of the firmware reduced by recovery before the DerpFest rom enough?

In first case, firmware 10.0.6.0 is mandatory or is the latest better?

anyhow, followed this thread's second post:

Factory reset.
Wipe data & internal storage.
Format data (yes).
Reboot recovery.
Flash FW.
Flash ROM.
Reboot system.
Profit!

Derpfest definitely sets a new standard in terms of rom stability and quality for the "cepheus". Everything just works flawlessly...
Does anyone know why the devs don't advertise it on xda? It would wipe out most of the roms here.

I completely agree!
A fantastic ROM, feels like a pixel/nexus, it just works (this also in part explains the low activity in this thread; nothing to write about).

Most discussion takes place on telegram. And call me old fashioned, but I hate telegram...
I completely agree. I just installed telegram only to follow the discussion over derpfest. I found a chat room with over 1000 people and they keep asking the same questions over and over again. Sometimes when I come home from work I want to read the updates, but it's too much and too much redundant information which just wastes my time. Maybe I don't know how to use it correctly yet otherwise it's just horrible.

can you tell me if the ability to delete all recent apk has been inserted with a swipe at the bottom like Crdroi and Syberia?

Please verify vowifi. That's what made me go back to miui.

Vowifi not working here in Germany, only with Miui or xiaomi.eu. The dev said over on telegram that he was going to look into it.
I'll post in this thread should one of the next releases make it work.
Aside from that the ROM is rock solid and super smooth. Makes my Mi9 run nicer than the OP 7T pro I also use.

    Hi to all

    The developers of derpfest ROM don't wanna share the links to Derpfest in xda.
    We have to respect this! Don't post any links to ROM or telegram derpfest groups!
    Here is the closed thread without links but with important infos:
    https://forum.xda-developers.com/Mi-9/help/android-10-derpfest-rom-10-official-t4032543

    So, this thread is only for advice, discussions and experiences.


    Future requests

    Please tell me what you want to have changed or implemented, the I would ask the developers if it could be possible.
    My list
    1. adding autocall record
    2. Adding flip display down to mute ringer
    3. Smart charge (charging only to a predefined % value)
    4. Adding display saturation level
    5. All closing button in recent app list
    6. And last to be 100% perfect with 5 stars: a system menu with automatic timebased network disconnect... Like leandroid app

    IBTD, a ROM with GAPPS included can never be 'the best ROM' for any device. YMMV but I'd like to decide by myself which Google bloatware I'd like to install.

    Thank you, can this be used on MIUI or only ASOP roms?

    You could try it with orange fox recovery (if bootloop you can easily deactivate the mod in recovery)

    Yes
    it's not possible to accept incoming calls while in a call already

    Ok, I do not have that problem with latest version of Derpfest, yesterday evening I was in a call while driving and could answer a new incoming call via BT-button in my car.
    This does not happen that often so I can't really say if it worked for me or not in previous versions.

    Are you running 20200218-version Laptapper?
    In that case; any problems/new features?

    Yes newest version.
    I've didn't recognized any changes.
    Running quite good as before
