Latest update messed up my phone(MIUI 13.0.2 Global) - Xiaomi Poco F2 Pro (Redmi K30 Pro) Questions & Ans

Hi! As the title says, my phone is unable to connect to WIFI, I keep on toggling on the wifi icon but it stay disconnected. USB connection seems to take a hit as well as my PC is not recognizing it as well even USB debugging is enabled, I had tried to factory reset the phone to no avail..
Are there anyways I can downgrade to a more stable OS or install a custom one?
Thanks so much!
edit: Phone now fixed! I Had to bring my phone to a cellphone repair shop and he reballed the CPU, problems are now gone. Thanks for the help!

Thanks, I have just enabled it thru OEM unlocking option in the developer menu and logged-in at my MI account as well.
Though, USB debugging is enabled, my PC here is unable to detect the phone.

How?
I could not even find my device when i use fastboot devices command in fast boot mode. Because of this i could not flash twrp also.
I installed drivers and connected the phone in all sorts of modes (usb debugged, usb undebugged, fastboot, system on, switch off mode).
When the phone is connected in switch off mode, i could see something like "usb device not found" message in pc. Tried changing desktop. But it's the same result.
I'm unlocked and on stock open beta 4 pie.

when your phone is in fastboot mode, can you see it in fastboot, fastboot devices? also, enable usb debuging, trust your computer on the phone when you get asked, try adb devices, any result? can you check what kind of driver version you have for android bootloader interface? try to download google adb & fastboot driver instead of xiaomi one. Also, do you use usb 2.0 or maybe 3.x? if 3.x, try 2.0..

Going back to stock ROM

Hi everyone. Could someone please direct me to a guide for going back to the stock firmware? I have been looking everywhere with no luck at all.
Thanks!

All required downloads are in the guide.
The Mi Flash Tool will lock the bootloader, by default, after flashing. If you don't want to do this, then change the option at the bottom of the tool before flashing (step 5)
If you wish to lock the bootloader, you must make sure the ROM region matches the phone, i.e. global ROM on a global phone.

Thanks!
However, I'm having a lot of trouble with the tool. It will not recognize my phone. I connect it, and the computer detects the phone. Then I click on "refresh" on the tool, and automatically the USB device is disconnected from the computer and the tool will not recognize it.
I have installed the Qualcomm and ADB drivers, rebooted and nothing changes.

Any ideas?

Sounds like a dodgy USB connection.
Try using the best USB cable you can find. If that doesn't work, try using a different computer. Fastboot and adb are very sensitive to the quality of the USB connection.
My old laptop will happily connect normally to my phone and I can transfer files with no issues, but from about a year ago I can no longer use adb and fastboot, with similar problems you are seeing. Using the same phone and cable I have no issues with my wife's laptop.

Question Trouble reseting fingerprint

Hi all. I had the screen on my pixel 7 pro replaced, and now I need to callibrate the fingerprint, but I am stuck on how. I put the phone in fast boot, went to https://pixelrepair.withgoogle.com/udfps to do it, but it couldnt find software to do it. I installed the usb drivers on my computer. I installed the windows drivers. I turned on developer options on the phone. I turned on usb debugging on the phone. I did look in device manager, and it didnt recognize the phone as a pixel 7. Any help is appreciated.

Did you turn on OEM unlocking in developer options and unlock your bootloader? Because you'll need to to use fastboot.
EDIT: go to settings > security & privacy > device lock > face & fingerprint unlock. Enter your password/pattern/PIN. Go to fingerprint unlock and hit the trash icon, then add a new fingerprint
I did not turn on oem unlocking, but I will try again. When I go yo settings to set up a new finger unlock, it says cant use fingerprint sensor
