You don't need all that stuff to use adb. All you need is the exe file and the WinAPI. And if you place it to somewhere in the PATH, you can run it from everywhere.

Works smootly and perfect. Thanks @Hack64

1) How can i turn off red battery light indicator while charging. I dont want this.

2) I would like to see per-app network settings/isolation options. I would like turn off mobile network per-app.

3) Is there a adb command to remove the bottom white line on home screen?

Thanks for your hard working.

Thanks

Microsoft Corporate Portal doesn't recognize the patch level. Cross checked with a different app and the corresponding method seems to return an empty string, but build props contain the correct patch level. Second screenshot shows what Intune has logged for my device. Anyone experienced the same issue?

edit: found the issue. The last change here altered the build.prop which gets called, when you use the "SECURITY_PATCH" variable to "ro.build.version.real_security_patch". But build.prop only contains "ro.build.version.security_patch". So as a work around you could create a new property with the value "2021-02-05" and then the patch level is visible in settings, aswell.

Network mode not working. (2G/3G/LTE) Only LTE working.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Master_T:
ROM seems nice and stable, great job.

The only thing that I really hate is the "customizaions" menu... it's seriously the most confusing UI I've ever used in my life 😅 I mean, sliders that look like buttons? Who had that idea? And for the settings that aren't just "on-off" but can have multiple values, you can't see the list of available options unless you drag your finger across. And the limited space in the "button" often cuts off the setting description. Seriously, what was wrong with the "classic" list of options like the rest of the system menu?

At any rate, the ROM works great and that is what's important, sorry for the rant 😂
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Master_T:
Well, i did find something that doesn't seem to work properly actually: the media notifications (the notifications shown by media players like youtube, spotify, etc.). They seem to be using the old (android 10 or earlier) style where they just appear as normal notifications. In android 11 they're supposed to be grouped together near the quick settings, like shown in the attached screenshot.

Can anyone confirm this? Am I just missing a setting somewhere?

2) Installed TWRP 3.5.0.0-9 official via TWRP site

3) Installed latest DotOS 5.0 and format data

4) Installed latest Magisk and manager

This ROM is very good ROM except some minor issues.

a) System UI crashes when I connect bluetooth device.

b) Sometimes its takes few seconds to unlock from ambient display & D2W not so responsive.

c) This rom draining little bit more battery comparing Android 10 ROMs. But, It has good battery backup comparing other Android 11 roms available now.

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] dedaol:
I was searching for a rom for my mi 9t, and wanted to try DotOS amongst others, but the download was really slow. So I had to skip it. Could you try to find better hosting for your builds?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] spring_roll:
Lol maybe the problem is your internet...? I tried it briefly and it downloads at 10 Mbyte/s, which is really fast enough😉
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Master_T:
In the last week I tried various of the roms for the mi 9T, to find my next daily driver after PicselIneperience reached end of development. I must say this ROM is still the most fluid and stable with great battery life, the other 4 roms i tried weren't even close. Great job! (although the customization menu is still super confusing and clunky to operate 🤣 but it's a small nitpick that doesn't impact the overwll great experience)
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] biggyk:
OTA failed so I had to dirty flash my device. OP says gapps only needs to be flashed once but after reboot google services kept crashing. I have reinstalled the nano version of gapps. I got playstore back but nothing seems to want to install. Just stays in pending. Any ideas?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] GiannisTP:
Switch to the Gapps version. A little bit of extra bloat from Google but you'll manage

Edit: Before flashing anything have you tried the usual? Clearing cache, clearing play stores' data, uninstalling updates?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Master_T:
I've finally found an issue with the ROM: when using a headset, the people I call all say that my audio is extremely low volume. This also happens when sending a voice message through Whatsapp/Telegram or similar apps: volume of recorded audio from headsets is extremely low. It's not a problem with the headset, I've tried three different ones and all have the same problem (they work fine on my other phone).

Is there any fix for this?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] totoy unot:
Issue 1: No 4K 30 fps for the main cam. = solved*

Issue 2: Bluetooth codec like aptx audio can't enable in developers option

Issue 3: Fingerprint performance not as good as miui

Edit:

I found a fix for anx camera to enable 4k 30fps, i just install miui core in magisk.

as for the bluetooth codec it only uses sbc. i don't know why it can't enable aptx unlike in miui 12 i can enable different audio codec

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Korii_SL:
Thanks man. That did the trick. All working fine now. And also i must say, I'm using this rom for the past few weeks. Battery life is superb. My battery lost about 30% of it's capacity (Around 2 years of heavy usage) and with this rom I'm still getting 6hrs+ SOT and a full day usage. Which i never got from MIUI stock or Eu rom. Lovin it
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] starflower:
Have been using this ROM for months now. My favourite ROM by far. Really unique aesthetics, very responsive and bug free, great daily driver.

I would prefer a Google-search-bar-free launcher. I thought of installing vanilla ROM with custom OpenGapps that leaves the default launcher. Can I dirty-flash the vanilla ROM over the gapps ROM?

Otherwise, I'm considering shady launcher, but haven't rooted. Does rooting break SafetyNet? I use Google pay frequently.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] LiamAtkins90:
Hi, yes rooting usually breaks safety net, there is work arounds to pass it with Magisk modules, but I don't know how reliable they will be. You can always dirty flash the ROM again to remove root access. But your situation above is why I haven't rooted, I use GPay frequently and my Banking app is hard to get around even with the Magisk patch.

Getting boot loops upon fresh installation. Any specific firmware to flash first?

Do I have to format data after or before flashing?

UPDATE: Okay so after flashing the latest Xiaomu.eu weekly ROM and flashing DotOS afterwards was working fine now. (just in case someone runs into the same issue)

// Found out that OTA is disabled by dotOS in general. Next question, lets say I want to dirty flash (I have GAPPS one installed at the moment), can I just dirty flash Vanilla over it and Gapps stays? And if I'm using 5.1.3, is clean flash recommended or dirty one does the trick also? :)

I clean flashed after flashing this global firmware

Xiaomi Firmware Updater

The ultimate script that provides firmware packages for Xiaomi devices.

xiaomifirmwareupdater.com

My model was the European version, but global firmware has been perfect so far.

Didn't mind settings up device again, only pain was banking app, but that took literally about 5 mins to set up on new ROM.

I always advise against dirty flash, because it can cause unknown problems, always clean flash, if it isn't too inconvenient.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] NiceSk1ll3r:
Few minutes before your reply I just dirty flashed mine. If I don't see any ground breaking bugs or feel like something is off, I'll clean flash. At the moment, everything seems to be working fine. I'm on latest beta Chinese firmware, although I should use stable EU or Global variant, but so far everything is good. Thanks for reply. :)

I think there is a problem when double tapping the power button to open camera. The screen just flashes white and after 2~3 seconds pops up the lock screen. After inserting pin the camera is loaded. I think this is permissions issue
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Miso_47:
Hi, There is a problem when double tapping the power button to open camera. The screen simply just goes white blank for few seconds and the lock screen pops up and asks for verification. If lock is verified, it takes you to camera. This is not a natural response. The camera should pop up and if I try to go to gallery, the verification must be asked only then.

overall rom feels awesome and very smooth.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] denizsen97:
Hi, first of all terrific job on the ROM, I just installed my first custom ROM on my mi 9t, and I'm never going back for sure. I encountered several small bugs which I want to report.

When I use the quick settings and the media player widget is present, I can't close the quick settings by swiping up,

The SIM passcode screen is shifted to the bottom to the point where I can't see the numbers after 7, and worst of all, I can't hit enter. (I disabled my PIN code for now but it is kind of a significant problem I think)

The screen stutters for a second before going into ambient mode

Double tap to wake in ambient mode sometimes gets disabled by itself, until I reboot the phone.

Other than these, everything works like a charm. Wish they'll be helpful!

some apps don't show content (like gravitybox) when dark mode enabled (all white and unable to distinguish) . don't know if is cause the os is forcing dark mode or something else.

also, anyone got a way to make apps immersive? (hide statusbar) i used immersive manager on A10 to set per-app immersive settings, but nothing works on A11. (trying to avoid statusbar burn-in )

Hi, I have a lot of problems with the ROM, like quick battery drain, phone freezing in AOD, status bar refusing to come down sometimes, elements of the interface dissappearing and so on. Since everybody says the ROM is great, I tend to believe I made a mistake.

I came from official MIUI 12.5, and I installed by formatting data through an old (January 2020) TWRP image I had on my laptop, then Gapps nano zip through the same recovery. Also, I did not install magisk or any other root software.
