Hello.
I have been trying to get a custom rom flashed on my Redmi 9T the past two days.
The problem I am facing is that the touch screen is not responsive with the flashed ROMs that I have tried.
ROMs I have tried:
What did make the touch screen work was to flash "boot.img" from one of the android 11 builds of MIUI such as "xiaomi.eu_multi_HMNote94G_HM9T_POCOM3_21.9.8_v12-11" or "xiaomi.eu_multi_HMNote94G_HM9T_POCO_M3_21.5.27_v12-11" after flashing the custom ROM, but this resulted in "Sytem UI" crashing and wifi not working. There were probably other things that didn't work but I can't have a phone without WiFi so this was not a solution for me.
After looking into what "boot.img" contains, it seems like it contains the kernel and other important system related components.I then tried to flash the following kernels over a new install of the custom ROMs "crDroid" and "PixelPlusUI 3.9":
But they did not help with getting the touch screen to work.
I also tried a combination of a "boot.img" from an offical android 11 EU MIUI ROM and these three kernels in the hope that I would keep the touch screen fix from "boot.img" and get wifi from the kernels, however every time the kernel was flashed the touch screen stopped working.
This leads me to believe the kernel itself makes the touch screen not work, and other things from the "boot.img" make the WiFi stop working.
So I have a few questions I hope someone can answer:
Thank you in advance.

So I have a few questions I hope someone can answer:
- When do you think Xiaomi will release the source-code for the android 11 kernels that they use in their new MIUI ROMs? As I don't know their release cycles.
- When will the firmware for the NVT-ts touchscreen version of Redmi 9T be added to custom kernels?
- Is there a way for me to extract the Android 11 MIUI kernel from "boot.img" and flash ONLY that, if that fixes my touchscreen and does not break my WiFi? (If this is legal/allowed/possible)
Thank you in advance.
