[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rockdriver:
Hi guys, i need help! i followed the guide as posted some pages before, coming from evolution x i thought it was pretty straightforward.. but even when i do factory reset, then format data, and then install rom and gapps i got stuck in twrp loop. what should i do?

Every time it doesn't reboot to system!
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] heinhuiz:
The problem might be in where you factory reset into. I would try to flash the global firmware first from https://c.mi.com//miuidownload/detail?device=1700361 and then repeat the same steps you used.

Also, I'd advise to use the official twrp from https://twrp.me/xiaomi/xiaomimi9tpro.html
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] heinhuiz:
Your main problem is that you're using too many words. Even if you're right (and in this case, you are), talking longer or louder does not help.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] kingkong1981:
Below, I am posting a link on detailed tutorial on installing official version of Lineage OS on K20/ MI9T (the non pro version) from official Lineage OS website.

Same should apply to K20 pro/ MI9T pro aswell.

https://wiki.lineageos.org/devices/davinci/install

See, if you can find clues on what went wrong or steps you missed.

Kindly, use the official version of TWRP that can be downloaded from link below,

Download twrp-3.5.2_9-0-raphael.img

Download page for twrp-3.5.2_9-0-raphael.img

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rockdriver:
Ok, i managed to solve this,

Don't ask me why, but after flashing rom and gaps another factory reset was helpful. To be clear, i already did that before flash, with wipe data. First time something like this happens to me.

Thank you to everyone for the help anyway!
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Pinkorek:
First of all, thanks for your work on this ROM.

Everything works fine, but I was wondering whether has anyone had an issue with SMS messages arriving late or only when screen is activated? Disabled battery optimizations for Messaging, Messaging service, Phone and Phone and Messaging Storage, which made no difference. I'll try disconnecting from wifi to test that out later. 9T Pro, global version, any tips will be greatly appreciated.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] paparansen:
i had the same problem, i did this and it is working now:

1. flash vendor

2. flash rom

3. flash gapps

4. format data

5. reboot to system
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] paparansen:
i discovered, that when playing games and exiting them,

the navbar & statusbar is gone - i need tp pull from top

of the screen to "re-enable"... is that a bug or a feature?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] sam00561:
Hi i am also having this issue only recieve sms when turn on the screen hopefully fix in next update.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
That issue with the default msg app is old & it'll probably never be fixed. I gave up using it, so I use google msg instead, wich works flawlessly.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Pinkorek:
Apparently it's a long-standing issue with LOS messaging app and monteverde_org on reddit figured a workaround for it. Enable ADB, connect to PC, run "adb shell dumpsys deviceidle whitelist +com.android.messaging". It'll say Added: com.android.messaging, at that point I disconnected from PC and rebooted the phone. So far so good, getting instant notifications the moment a message is received, even after the device has not been used for an hour.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] WallixPro:
Hello, thank you for a great lineageOS, everything works fine.

I did it like that:

1. fastboot boot twrp-3.5.2_9-0-raphael.img

2. install image > twrp-3.5.2_9-0-raphael.img

3. reboot > recovery

4. factory reset / format all

5. reboot > recovery

6. install > firmware V12.0.5.0.QFKMIXM (2021-03-04)

7. reboot > recovery

8. install > lineageOS-18.1 include gapps (..raphael-gapps.zip)

9. reboot to system

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rockdriver:
Has anyone else noticed that this rom is pretty slow when loading internal storage?

Not the whole rom, that works pretty snappy, just when loading file and pictures.. am i the only one?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Toni Suwanto:
Yup, noticed too
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rockdriver:
Do we have any way to solve it? It's pretty annoying
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] kingkong1981:
In my case,

I receive SMS instantly using default messaging app .Even though I can hear the SMS tone, the screen doesn't light up with phone in locked state.

Default gallery app loads image & video thumbnails quickly.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] murakh:
Are you sure about this? I know I *sometimes* seem to get SMS instantly, however most often I hear the notification tone and when I check the actual message it shows as received X min ago (usually around 2 to 5 min ago). With screen on it shows and notifies instantly (e.g. when waiting for 2FA code) so in general this is not really a big issue for me.

And I have exactly the same issue on Lineage on the Poco F2 (lmi) so I'm also convinced it is an inherent "problem" / bug / feature with the default lineage messaging app.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
Yes, it's a lineage bug, that's why other sms apps work perfectly & lineage does not.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rockdriver:
I've tried the default gallery, it's faster but nowhere near fast as other rom! Maybe i should try to format data to ext4?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Zafrkant:
Hi,

I've read all thread and tried many solutions to have LOS encrypted and that I can still do have backup that I can successfully restore TWRP backup when I needed. As remmember I've tried following in couple days back.

Format Data and start with clean flash of firmware, ROM, Magisk.

Backup without pattern and when restore and boot I have semi usable system withont navigation and notification bars displayed, also displayed in other tries. If pattern is enabled it just showing "System is starting",

Many recoveries TWRP, SHRP, PB, OFox,

Firmware 12.0.2.0, 12.0.3.0 versions,

Older LOS 18 and 18.1 versions,

Flashing fastboot MIUI and than TWRP, ROM, Magisk.

Format data as EXT4.

I don't like to trade security with DFE or either to return to MIUI, but in my case I have two options eather to have encrypted system and no usable backup that I can restore or to have unsecured phone with option to have backup if needed. Please help.

Thanks in advance.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] sam00561:
Unsecured with available backup is the way to go don't worry.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] FallenJedi:
Really? I haven't faced this issue at all. I get all my messages instantly and without any notification delay! I guess I'm one of the lucky ones here.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] olus:
stay encrypted without backups. you can use apps like titanium backup, swift backup etc for backing up most important things, settings, apps, etc.

i cant understand why so many people recommend an unencrypted device. yes, i know "i have nothing to hide, im not criminal, they can look at my phone, my house and even in my ass. i have nothing to hide, come and look..".
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
This is not addressed to anyone in particular, but yes, you're right. We're seeing too many people recommending unencryption here. Perhaps under the influence on what they read in k20 pro telegram groups, which I use to get my daily laugh fix. You find all kinds of stupidity there.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] sam00561:
The biggest security flaw is unlocking bootloader to start with after doing that I'm not sure what levels of security people expect in reality.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
Even if they pin exactly what you said in a thread title or a telegram group, at some point people start to ask you about encrypted or decrypted.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] sam00561:
I know
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] ko20010214QQ:
When I use NFC, it doesn't work. I mean, when I put my phone close to the NFC card, nothing happened except to turn off the NFC function! I set the NFC function ON in the settings, but when I get close to the NFC card, it turns off NFC automaticlly! I flashed an ACIP ROM into my phone. It supports NFC function, but unfortunately, it doesn't work either. Maybe it's my fault? Why can't I use NFC? It drives me crazy, and it's an important feature for me.

For anyone interested on compile this on your own. It is possible to compile everything but it only boots to fastboot for me: https://github.com/erhan-/docker-lineageos-raphael

If anyone wants to work on this, they can create a merge request.

@abhishek987: Do you have time to create a new build for us please?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] sam00561:
Does this mean atm there is no maintainer and the rom is in the wind.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] ESmazter:
No he is still the maintainer but is just busy with life I guess. Compiling and uploading also takes quite some time. So that's why I would wish to have a docker image for that so that either we rent a server and build weekly or everyone can build on their own.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] sam00561:
ok i see good idea
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Redsandro:
Which LineageOS 18.1 source do you mount in order to compile this? That's the only required submodule, right?

I have tried to compile it today again but it still only goes to fastboot. It does build successfully so I do not know what secret we are missing.

Really nice that you are trying to compile it yourself. I will give it a try tomorrow.

I guess you don't have any error messages/log since it directly goes to fastboot?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] ESmazter:
Thank you but that's me. ;)

No I don't know how to get logs at that point. In what situations does it go to fastboot as well? I have tried to install a different kernel as well to see if it is a kernel issue but same problem.

Maybe OP would share his secret if we collect donations and pay him some money.

Maybe this does not work because it has no prebuilt kernel?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] paparansen:
did you format data ?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rootthecause:
Hi!

I got my Mi 9T Pro two days ago and since I love LAOS on my OP2, the build by abhishek987 was a major consideration to purchase this model.

I bricked it a few times because of encryption (unbrick with MiFlash), but after I figured out about Disable_DM-Verty_ForceEncrypt the installation worked like a charm. As I'm reading on here, it seems that encryption is possible, and I would like to do that, if it is workling reliable (without eating data) and also without needing to reinstall all apps and configs. Is that possible?

I've chossen the Gapps build (20210222 Unofficial Rapahel Gapps) because as far as I know there is no such Open GApps "lite" for Android 11. The deep google integration is bothering me, especially the assistant. I think I disabled 99% of that suff, but I whish to be more sure about that. So is it a "take it - or leave it" option when it comes to Play store? Can we expect an Open GApps build for Android 11?

So far I'm using LAOS 18.1 on the 9T pro without major issuse, so I'll use it as daily driver - big shoutout to the developer abhishek987! I whish to donate something, but I respect his words in the donation description. So instead I think about donating to LineageOS LLC.

Bugs'n'stuff​

So far, the only bug I have is the 48 MP sensor. I have tried the ANXCamera (which gives me the other lenses and a ton of funtionality back compared to the stock ROM 🤗), but the resolution is 12 MP and when I turn on 48 MP Mode, its 2,8 MP ?!??? Even with the 48MPFixR (ver. 200 and 201) I had no luck. Was anybody able to get this working?

Portrait Mode is only working in Camera PX (GCam Mod), otherwise I'll get an error in ANXCamera.

Nice stuff​

Try the Wifi Bonding Plugin in Magisk - I was able to hop from 144 Mbits local WiFi speed to 300 Mbits! This is really usefull when transferring data locally via AirDroid or just using our 200 MBits internet connection.

Feature Request​

While using the Stock ROM, I was able to unlock the screen when only a fingerprint symbol was shown.

Now in LAOS I'm unable to unlock while the screen is off. Enableling inactivity display fixes it, but I dont like having the clock and other symbols displayed - I whish it was at most only the fingerprint symbol, but it would be even better to have the fingerprint sensor always on when the display if completely off. Is there a way to do that? With inactivity display / fingerprint on, battery consumptions doesn't seem like a big concern, but I have to investigate that more over the next days.

This Request was solved! See the post on the next page by 01Destroyer

You could try NikGapps

Hey have you had any luck with this? Sitting in the same boat.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] olus:
i get it to working. just amazing, because no magisk modules (hideprops, sqlfix,..) needed.

i just hide magisk from play services, gpay, playstore and google app. after that i get safetynet pass and can add paypal to gpay witbout problems. a few hours ago i tested paying in store and it worked!

btw. chrome sync issue is gone with nikgapps. with bitgapps i cant get chrome to sync my google account.

magisk is working fine with this workaround few posts ago (flashing older magisk, then updating app and flashing newest magisk..). everything else will end up in fastboot mode. you can survive this by wipe system then flash rom+gapps again, this will remove magisk and bootloop to fastboot mode.

almost all features are there (screenoff fod, notification bar customization, ..)

i just miss advanced power menu (reboot to recoveryy..) but thats not worth to mention 😅

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] FallenJedi:
Device Encryption: You will need to format data to preserve encryption when you move from Miui to a custom ROM.

Gapps: You can use NikGapps Core. If you have already flashed any other gapps you will need to clear data or do a fresh install.

Portrait Camera Bug: You can search in the telegram group for a modified 48MP fix for ANX cam. This mod will also solve the low resolution issue of front camera.

Yeah, would like to know that too. I can selct ANXCamera as standard cam, but double press the power button will only get me to the lockscreen. Also didnt found a setting in ANXCamera.

However, Opencamera has a setting for that, and works with locked screen. It can be found in Settings -> more camera settings -> Show camera despite lock (or something, not eng as native language used). Is there a worround for ANX?

OMG! Why haven't I found this setting earier?! I swear, I googled before asking.

Thanks a lot! That's it!

Gonna edit my first post.

Now there is something else I wanted to address:

Automatic Brightness control - it's very unsmooth when it is adjusting the brightness compared to the stock ROM. Also the reaction time is very slow: about 3 secs from dark to bright and 5 from bright to dark. I read in this Reddit post, that it could be a bad calibrated light sensor in firmware. It is also present on my OP2 with LAOS 17.1, but I didnt knew it could be done much better until I had the 9T pro with stock ROM. Is anybody having the same issue in LAOS?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] FallenJedi:
You can flash the 48Mp fix from post #584 via TWRP. But then again it will be pain in the ass to remove it in case it doesn't work for you. It is easier to remove it from Magisk.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] FallenJedi:
Yup, the autobrightness is definitely a little janky. But then again this ROM hasn't been updated since Feb. Most of the other A11 ROMs have fixed the autobrightness issue though. HavocOS (my personal fav), ArrowOS are decent alternatives to Lineage.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rootthecause:
Was the fix implemented just reccently? I mean, its a nice to have, when it works smoothly. So I could deal with that when an Update fixes that in the future.

Might be a dumb question, but what are the limitations on this? Would it be possible to Magisk flash Gapps and turn it off later, or even something like a dual boot?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] z1022:
Is the ROM update discontinue ?
