I hate wiping as much as you but if you backup your apps with something like neo-backup you won't need to reconfigure them in reinstall.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] moroi01:
So assuming that i will do that. What is the correct step order here.

1. Boot into recovery

2. Wipe data/wipe cache/factory reset

3. Sideload Lineage

Is this correct?

Above, is a procedure for dirty flashing, why dirty flashing is not working though.? Is still not clear for me . Is it just my device? Is working for anybody?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] don.nasco:
Did you read the Flashing instructions at the OP? Also, please check that you're using the latest platform-tools.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
Flashing Los 20 through ofox recovery instead of adb.

Flash the attached recovery

Format

Flash the attached legacy to retrofit file

Rom

Gapps (whatever you want)

Reboot
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] moroi01:
Reading the OP, lineage has his own recovery. Will it work with other recovery? Also what means "retrofit file" ?!
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
The retrofit file is the equivalent of the super empty file. Everything works fine, otherwise I wouldn't post it here, right? It is just for people who prefer recovery flashing, instead of having headaches with adb stuff.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] BranMakMorn:

Thank you Sir.

Worked flawlessly.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] geearf:
Sorry I haven't moved to LOS yet so I wouldn't have a good answer for that yet.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] z1022:
You mean, better use adb to flash the rom. Right?

Hi I did all the instruction. I was able to install rom and gapps. Booted the phone successfully, but when I install apps I encountered error below. I can't even update pre loaded apps. Please help. I really want to try this rom. I tried Pixel Experience and i didn't encounter this kind of issue.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] moroi01:
Hey buddy. Thanks for bringing this. Can you please describe like i am 5 the proper way to install this fresh? my issues with dirty flash are simply insurmountable. Not sure if I should use the lineage recovery, or Orange Fox. If OrangeFox, how should I properly go from Lineage Recovery to ORange FOX? I will do "the horror" and spend 2 days reinstalling my phone from scratch.. Can you please be so kind and confirm what android security patch is installed on the rom?

Later Edit: I guess what i am trying to ask is that the OP flashing procedure is still valid? because i see a lot of times that is insisting on DO NOT USE ANY OTHER RECOVERY, and the colleague @mauam 4 posts up, is saying something about OrangeFox. I am confused about that. Also if keeping Lineage Recovery, do i need to flash again the super_empty file? i am just trying to flash latest security patch oh android, with the little hassle as possible, if possible keeping all my data (photos, documents etc) . My phone is encrypted, really hope that i do not need to wipe all nand memory.

Hello there.

I wanted to try LOS on my K20 pro moving from Xiaomi.EU 12.5.6; after installing latest version via Orangefox it just goes back to recovery, and nothing happens.

Any suggestions how to deal with that?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
Simply follow those instructions.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Xenosage:
I did follow your instructions, and that's the result. I've also noticed there is a message in the very beginning:

"Android Rescue Party trigger: Possible solutions?

Either:

1. Wipe caches, and/or

3. Clean-flash your ROM.

Hello, When I call my wife, I have no dial tone (1/4 second then nothing) but the call continues in silence before going to the answering machine within normal time limits if my wife does not answer before (his phone rings normally). This tone problem is only present when I call my wife, for my other contacts no problem (by vowifi, 4g, 3g etc... ras). When my son calls his mother he has no worries. The APNs are well configured, I really don't understand where this could come from but the link is my passage on LineageOS 20...?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] skallorfeus:
I identified the bug: when I select: preferred network type 4G", the tone problem is present when calling someone who is on 4G/5G (no problem, it is on 3G). The problem disappears when I chose 3G in preferred network type with the official xiaomi ROM I didn't have this problem, does anyone have a solution? (I have already cleared the cache using recovery mode)
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] parhit:
Hi there :)

Huge thanks @albata for this ROM updated with the latest security patches.

I have two questions, as I am already under LineageOs 20 (another unofficial ROM not maintained since last september):

Is it possible to make an OTA update directly? I just tried but it rebooted the device to TWRP and I didn't know what to do :)

If I use TWRP, will I lose my data? What is the procedure to do the update without losing everything?

If I follow this tutorial from @mauam I will format my phone and therefore lose all my data.

Thanks for the help <3
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] moroi01:
So i did everything as explained. Install fresh with Orange Fox, after formating. Install the proper Gapps, x64 from the link above...everything works, but Whatsapp is giving me something similar (mine is Unsuficient storage) but since i barely formatted, i got 100GB free. Looking through internet a lot of people are getting that. Not sure what is wrong.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] fraction007:
Maybe corrupted files. Idk... Did you follow these steps ? clear the cache partition in the recovery before rebooting the device after flashing?

Maybe you can try it now

In recovery select

I encounter the same thing. Literally same thing, it was making me go crazy. So fortunately although i downloaded the gapps from the same place, described here, i had 2 file versions of it. The last one is broken, the "old" one worked for me. Smaller in size in my screenshot is "the good one" . Whatsapp is working and installing ok.

(nevermind the naming, when i flash things in ADB i just rename them "gapps" and "rom", but is the same package downloaded from here https://wiki.lineageos.org/gapps/ ---- version Lineage 20, Android 13, ARM64).

Not sure how can you get your hands on the old GAPPS zip file tho' ... i can provide it for you if you can give me an FTP site.

Thanks for this wonderful rom! I've found one little bug. Sometimes, when I unlock my phone, it opens with the recent used apps. I can't press besides these apps to continue. I've to close them one by one, before I can go to the homescreen. The clear all button (on the far left) isn't there and the screenshot button in the bottom is missing as well.

Update: It happens when you turn off the screen with recent apps opened.

I just can't get used to any other launcher. I only use 6 features:

No sticky apps on home screen

Increased home screen app icon density

Increased app drawer icon density

App drawer vertical scrolling

App drawer horizontal groups

Home screen gesture to open app drawer

But the addiction to Nova launcher is off topic. Just count this as "this 'recents' incompatibility with Nova bug affects me too."

Also SELinux is enforcing for me, which is nice.

The only problem that I have now, is that I can't get it to pass SafetyNet. Even with Universal SafetyNet Fix and MagiskHide Props installed, it still fails the CTS profile match.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] rodeoslide:
To get Gpay to work with a valid CTS profile I used Universal SafetyNet Fix and MagiskHide Props Conf 6.1.2 from the original source: https://github.com/Magisk-Modules-Repo/MagiskHidePropsConf

Go to a terminal and enter "props" as root. After changing to a valid profile it passes all checks. Still, in Gpay app the NFC icon is greyed out. But paying with the profile once NFC is activated works like before.

Thanks for this great rom.

Did anyone manage to get ANX working properly?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] sp3c/sh:
It will work, but it has a few extra steps.

First you will need to sideload magisk, and then (after enabling zygisk from the settings), install and enable the "Zygisk-LSPosed" module. Reboot your phone.

Then, you will have to get an xposed module called "FakeGApps", v4.1 will work.

(https://github(dot)com/whew-inc/FakeGApps)

Install it and (through LSPosed) enable it for the system framework. After a reboot, signature spoofing should now be enabled and you can proceed as you normally would.

All location providers I tried seem to work just fine, and so does google maps (with an occasional nag about google play services not being available, which can be disabled from notification settings).

Aurora store works perfectly for me as a play store replacement, and notifications seem to work properly.

Not sure what it means, but you can theoretically ignore it. Do so at your own risk. Look at the README/instructions from the following locations for educational purposes:

When setting Mobile Data Warning and -Limit, "Settings" app crashes. Close settings, re-open settings, go back to "Network and Internet", phone reboots. After reboot, data limit is turned off.

Interestingly this happened once only. After two reboots I can chance the limits just fine. I'm not joking though. Not sure what caused it. Perhaps someone can see if setting a limit for the first time triggers the crash, or if it was just a fluke on my end.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] danielfreund:
hey. did u use the same lineageos recovery to flash a different rom?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Redsandro:
Sorry, my words were misleading. I wanted to wait for new version before trying, so initially I flashed other rom (LOS 18) in stead of this one.

Then later, I became impatient so I flashed this rom (LOS 19) to take it for a test drive. Then I wanted to flash the previous rom again in order to restore backup, but I couldn't install it using the TWRP recovery. I guess the wipe-super change prevents the previous LOS 18 from installing. So I just installed a clean LOS 19 again, and start setting it up.

I think if you want to go back to previous/different rom, you need to un-retrofit and un-wipe superpartition. I don't know how to do that.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
You must not use any other recovery than the provided one. Check the notes in the OP.

To undo the retrofit stuff you need to fastboot any regular recovery, a normal ROM & format, that's it.
