I think you should do a complete clean flash, fastboot global stable miui rom,then install twrp,and then clean install Android 9 roms by wiping all the cache,system,internal storage etc.,may be this could help.

I'm currently using this firmware: fw_hydrogen_miui_MIMAXGlobal_9.1.24_893529ec22_7.0
It works perfect for my region and WiFi speed is the best.
I recommend you to try different firmware versions first of all. You can download them here: https://fex.net/s/xfecbzt
If it doesn't help, you should flash official firmware using MiFlash and then try to use MSM Xtended again.
BTW, have you checked another Pie ROMs on your device? Is mobile data working correctly with them?
Nope, it should work correctly in Germany as well as in other countries.

Firmware is a collection of things that run at a low level which contains all the primary things like radio baseband software, modem drivers, etc.

can we flash them with our custom roms and kernels? or just they are already in our custom roms?
Click to expand...

_firewall_ said:
Custom ROMs don't include a firmware. So, you should flash it separately if have any issues. It could be flashed or updated anytime: with the ROM, when the ROM is already flashed, etc.
But be careful and flash the correct firmware for your device only (Helium for Helium, Hydrogen for Hydrogen). Otherwise, your device will be bricked.

sorry if i am asking too much,but i am curious to know,how can we flash them via recovery or via fastboot(via computer)?.,should we flash them if our phone is working well & good or if we are getting some issues with call,wifi,bluetooth etc then we have to flash it only...,secondly does it gives any performance increase? (as i think the latest versions of firmware are getting better drivers for our hardware like wifi,bluetooth etc...correct me if am wrong with this).

_firewall_ said:
You don't need to worry about the questions. It's ok and better to ask before applying unknown actions.
Firmware should be flashed via TWRP only. I recommend you to flash the firmware if you have any Bluetooth, WiFi or mobile network issues only. If your device works fine, you don't need to flash it. It may increase network speed as well as slowdown it (depends of your location).

Did you flashed the latest firmware given in the link? I think it may work, and do a clean swipe data and cache, then install latest firmware.
You can also try the latest Android 10 beta lineage built may be your problem get solved.

Just flash the full 3.2.6 rom and you'll be back.
The OP support flashback seems to be the only solution for those that are on stock recovery.
Those with unlocked bootloaders with TWRP have successfully flashed back to MM ROMs after flashing CB 8.

No, flashing a kernal won't result in a different twrp. BUT inside the kernal downloads he also has a few Twrp releases. You will need this one https://forum.xda-developers.com/devdb/project/dl/?id=22806

Well then it's not a Twrp issue.. Ask the rom maintainer.

Don't own this device so a few questions.

Okay, so, one of my friends has a OnePlus 3 and it disappointed in the battery life after the Nougat update, he wants to roll back to Marshmallow.
So,
1. Is rolling back to Marshmallow possible after a Nougat update? Are there any risks for flashing Marshmallow on Nougat's bootloader?
2. Can someone tell me what is the latest stable (don't want betas) Oxygen OS based off Marshmallow.

Remember that op3/3t N have f2fs file system which is unsupported on 3.2.8 (MM). You'll either have to use an old version of custom kernel (I think only bluspark supported f2fs at that time) or convert to ext4 in twrp. Other than that there should be no issue with flashing 3.2.8 over N

So far as I know, you can't downgrade the Binaries. But still u can manage to find someway to leave A11 and back to whatever A u want since customs ROMs ( based on stock ) are seems enough

Flashing Custom Recovery and/or ROOT on A50 is quite different with few extra steps. Do the searching in our forum, u'll find the information u need.
P/S : Always read carefully ROM's Install Instructions, it cover all the info u may need!
