I really like the rom, its beautiful with custumisations.

But actually since start, the phone gets hot often. Not miui-like hot. I also get batt drain during this. When i flash los back, the phone stays normal and does not have this issue.

Im on latest version. Have no magisk mods installed. Just some ui customs through derpfest menu. I dont see anything weird at batt menu. It also gets hot in my pocket. Had flashed miui stable before this and as i said, los didnt had this issue.

Some others with the same issue? :) i still stick with the rom because i like the looks and speed of it tho

@VortexHD - I noticed that you got Santander to work using Riru-momo, did you manage to get it to work with the Mi11 and the latest build of Derp?
I followed the instructions and it doesn't seem to work for me - Thanks for the great rom.

Hi, first timer here.

I successfully installed everything (including Magisk) and it all worked fine... for an hour or so.

Then I realised that I couldn't install Netflix and also couldn't use contactless payments since my bank app won't allow rooted devices. I then discovered that SafetyNet showed a failed certification for both basicIntegrity and ctsProfile.

After searching for a bit I found out that I could install SafetyNet Fix in order sort it out, still didn't work. Then I discovered that there was a Canary channel for Magisk and installed since it was supposed to fix the issue. I uninstalled the stable Magisk App and installed the Canary edition.

After installing said edition, both basicIntegrity and ctsProfile were enabled so I thought It was all solved.

Boy was I wrong... All my root privileges are gone, and also Magisk isn't installed at all. Only the app is installed (I reverted to the stable edition again, still no luck).

So I tried to flash Magisk again using the sideload method but it just won't fix the issue. The process itself doesn't show any errors, it just doesn't give root access to my device anymore after rebooting.

Any ideas on what can my mistake be?

EDIT: By the way, forgot to mention that everything else works flawlessly, huge thank you and congratulations to the developers for allowing me to escape MIUI ;)

EDIT 2: Forget it, nuking absolutely everything and starting from the bottom solved everything.

Does this also works for the Mi 11 Pro?
Because its available for the Mi 11 (Non-Pro)

I have the Mi 11 Pro, so I could be testing.

So far, I have been using MIUI with all my successive Xiaomi devices.
But on the last versions of MIUI, Xiaomi introduced a superbly stupid limitation in their quest to mimic Apple.
And that is : it is impossible to use gestures with a launcher other than their own MIUI Launcher (which I really do not like).
There was a workaround for that but that does not seem to work anymore.

So I went searching for a ROM not based on MIUI and found this.
After several tries, I was able to get this to boot (probably not working because I had not installed MIUI Stable).

I have been so used to MIUI lately that I did not remember what a custom ROM looks like.
Man, is that a change.

Of course I miss some of Xiaomi features like the themes or the ability to customize AOD to your liking.
But for the rest ? Nothing to regret...

There's one question i have though. It concerns the camera. I noticed in camera settings that resolution can be set to 27MPix max when the hardware is capable of 108MPix.
It's not something I will use on a daily basis (and even then not sure I'd notice the difference between 108 and 27) but would like to know if that is normal or if I did/understand something wrong.

    Hey, so I'm loving DerpFest and there are practically zero bugs, but one big issue I found is that people have told me that they can hear themselves in regular calls, VoIP calls, and social media app (e.g. Telegram, WhatsApp, etc.) calls, especially on speaker mode (less noticeable on handset mode). I did some research and found out that this is a common issue with AOSP ROMs and Xiaomi dual mic phones, since the AOSP ROM does not correctly use the two mics for noise cancelling. Has anyone else experienced this on LOS, SSOS, DFOS, or any other AOSP ROMs on the Mi 11? I looked into editing /vendor/etc/sound_trigger_mixer_paths.xml as suggested in the Poco F1 echo fix XDA thread, but I don't think DEC7 and DEC8 are the correct dual mic IDs for this device. If any devs can figure this out, I'd be happy to buy you a 🍺 for your help in making AOSP truly perfect on this device with this one important fix.

    I'm facing some issues with the Google Assistant, as it shows 'This feature is currently unavailable for this language" whenever I try to enable 'Hey Google and Voice match'.

    My current device language is English (UK) altough I'm facing the same issue with Spanish (Spain). Any ideas?

    Also, as other users have mentioned, I believe that the microphone volume is quite low (eg. Whatsapp voice notes)

    Everything else works pretty good. It's a daily for me.
    Hi guys! Finally I've managed to flash DerpFestOS. I used TWRP to change the slot and flash the ROM. Thanks for all the advices and help.
