[MENTION=375939]bejam[/MENTION]: Which channel is your 5 GHz WiFi set to? In which region/country do you live? You might eventually be running into problems with specific channels not being supported (e.g. due to WiFi region configuration mismatch on your device).

Try to set your WiFi AP to channel 40 and use a channel width of 20MHz, this should in theory work in the vast majority of countries and offer highest compatibility for WiFi devices. AFAIK only Russia and South Africa will require DFS (Dynamic Frequency Selection) to be supported on channel 40. But both countries require DFS support on most of the 5GHz spectrum anyway (unlike the rest of the world).

The test above is meant to evaluate whether 5GHz networks are generally broken on your device, or if this is just some sort of incompatible settings/configuration in place. E.g. if your device uses a WiFi region code, which does not Match your country, it will use Channel rules of another regulatory domain and will hence eventually not support channel configurations which would otherwise be allowed within your country. If your AP uses a configuration which your device does not allow/support, you won't be able to connect.

Please further let us know if you are using any Magisk modules (if yes, which ones?). Specifically interesting are modules surrounding WiFi (e.g. channel bonding, 5 GHz disabler, ...)

Is your Widevine still L1 after changing to Chinese FW/vendor and back?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Shaoliann:
Hello, I tried many times to flash it but without success, I think I will need some fool-proof instructions. So I will get my phone back to the stock firmware with android 9 and start from there To do so I will use the MIFlash utility. My phone is already unlocked and it's the chinese version. Here are the steps I've done and correct any mistakes I might have made:

Unlock dev options, enable usb debugging, go in fastboot and send TWRP img through adb (fastboot). (Do I need to update the MIUI to the latest version before starting the process?)

Flash android 10 from zip. (What exactly do I need to wipe before/after?) In my case I seem to have a problem with my TWRP/Android 10 zip cause I have an "older" version of TWRP that works fine for that flash, but if I update it to the lastest version I get an Incorrect Zip format error. So after I flash android 10 I go back in Fastboot and send the latest TWRP to my phone. (At this point my phone still boots and is on android 10)

Then I flash Lineage OS 17 from zip. (Once again, what exactly do I need to wipe before/after?)

Next I flash Open Gapps Nano for android 10. (Once again, what exactly do I need to wipe before/after?)

Finally I reboot to system and depending on the manipulation I made (made some mistakes a couple of time) sometimes it would only go to fastboot, only go to recovery or the closest I got was the logo of lineage going for hours (let it sit overnight and still the logo moving).

So, anyone could help me understand what I did wrong?

You said you flashed "Android 10", I guess you refer to the firmware, but you didn't mention vendor... Did you flash both?

I installed los17 using the chinese firmware+vendor combo found in this thread, with the same version of twrp, maybe you should give it a try?

i was on pixel experience before flashing this.

step 1 : on recovery, wipe dalvik, cache, system, vendor, data.

step 2 : flash this vendor (Indian vendor is better in widevine l1 and fingerprint scanner accuracy.)

step 3 : flash the lineage os 17 zip

step 4 : flash this gapps...

Hello,

if trying to open the settings for immersive mode (to hide status bar and bottom keys), the settings app is going back to main screen or throwing an error. On LOS16 mido it was working fine. Neither does it make a difference if using gestures or arrows to navigate.

Any ideas? Is it LOS17 related or device related? I have no gapps nor magisk installed, just plain LOS17.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] dangerous_johnh:
You should be fine if you're coming from Xiaomi.eu Android 10 since they package the Chinese vendor and firmware in their installation zip anyway.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Bristow Xavier:
a single package contains vendor + firmaware...

this is necessary because... devices which are launching internationally requires the firmware and modems of that particular place...even if the Indian vendor supports a Europe variant device, it will cause some network reception issues...

Regarding firmware + vendor RAPHAEL-V11.0.2.0.QFKCNXM-10.0-vendor-firmware.zip from https://downloads.akhilnarang.me/MIUI/raphael/ : I was able to flash it and afterwards flash lineage-17.0-20191013-UNOFFICIAL-raphael.zip wihout any issues. Device is booting fine and not crashing. I was using TWRP twrp-3.3.1-21-raphael-mauronofrio.img from this thread https://xdaforums.com/k20-pro/development/recovery-unofficial-twrp-xiaomi-redmi-t3944363.

What I did:

1. Unlock bootloader

2. flashed above mentioned TWRP version and afterwrads directly boot into it (otherwise it was replaced by stock MIUI again)

3. followed https://xdaforums.com/showpost.php?p=80410089&postcount=30 (using the above mentioned firmware +vendor)

4. Having LOS17

Edit: https://www.youtube.com/watch?v=cBj3-A8Zxko is a good video, and in the description of it there are more links to other usefull videos. I do not agree with all steps he did (e.g. I did not apply Disable Force Encryption), but all the videos are providing a good overview what to do and how. Also backing up EFS and persist partition is explained and seems to be usefull.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] El Kikos:
I did the same => no problem !

For your problem in the 2. : you need to delete or rename this file "/system/bin/install-recovery.sh". You need to be rooted btw to have access to this file. After that TWRP will be by default.

I'm waiting for the eu vendor which will be available soon ... I hope :D

Do you know if it's possible to have microG on android 10 ?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] testman86:
Yeah, me too. I am also living in the EU, but everything has been working fine so far with the mentioned chinese vendor + firmware.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] xXRapToRiXx:
I can also confirm the RAPHAEL-V11.0.2.0.QFKCNXM-10.0-vendor-firmware.zip working with my european Mi 9t pro. No issues with connectivity either. What I did was I backed up my System and Data in twrp (did not want to make a clean install of lineage after vendor upgrade from my previous 10.4.6.0). Then I flashed the new vendor and without rebooting into twrp I wiped system and data and restored my backup from earlier. Lastly I flashed Magisk and DFE because if would not boot otherwise.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] xXRapToRiXx:
Holy Sh!t it worked, thank you so much. Now this rom is 100% flawless for me xD

I followed the steps from 1 to 11 exactly and did not have to mess with any magiskprops to get it working. I will try it out in the store tomorrow.

Update: Unfortunately it did not work in the store. In the app there are no error messages, everything seems fine tho when you try paying in the store the terminal does not recognize the phone.

Update 2: I think I figured out the problem: NFC does not seem to work with the new Chinese Miui11 vendor. I will flash old Chinese 10.4.6 vendor to try this again...

Update 3: Now I can confirm NFC not working on the global Mi 9t pro on both chinese vendors (10.4.6 and 11.0.2) I tested this with another phone of mine and both receiving and sending NFC tags failed.

It seems like you have not followed the instructions correctly. If you do as follows exactly, it should boot.

4. Flash Magisk if needed.

1. Unlocked bootloader

2. Install TWRP (Mauronofrio's version)

3. Wipe data

4. Flash LOS 17

5. Flash gapps

do I need to install the vendor (fw-vendor_raphael_miui_RAPHAELGlobal_V10.3.2.0.PFKMIXM_55396ac730_9.0.zip) again?

Cheers!
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] olus:
You need to follow the instructions clearly. They say you need chinese or indian miui11 vendor/firmware.

So you can answer your question by yourself:

Do you need to flash "fw_vendor_global_v10.zip" again?

I also get this, I originally started rebooting every 3-4 days, I'm now rebooting every 1-2.

The more I use my phone, the more I can feel the lock screen and notification drawer slow down.

It can literally get so bad that entering my pin on the lockscreen, every digit pressed stays visible for ~5 seconds, not only is it a usability issue but also a security issue when a casual observer can see all your PIN digits highlighted and onscreen for ~5 seconds.

Apart from this I otherwise love the ROM.

It's weird though, apart from the lockscreen and to a lesser extent the notification drawer, everything else is lightening fast, all apps, etc. But then you lock the screen again and it's a lagfest to unlock it again.
