mi10 t pro

I accidentally deleted all the efs blocks on the phone :( Could you please provide me a backup file with efs blocks. Thank you. my phone is Mi10T Pro (apollo)

I've bought this smartphone yesterday and I immediately noticed that the volume of the microphone in voice messages is very low and it's like is muffled. I tried to use the recorder app or to make a video, and the sound is perfect there. So i figured that the problem is in voice messages...
