Can you link the ROM you used?
I opened the device, did the test point, and put the V10.0.2 rom with MiFlash, but no succes, I'd like to try the 8.1 version.

Did you flash the critical?
Did you flash the critical?
*If not try this: https[:]//forum.xda-developers.com/mi-a2/how-to/guide-how-to-unlock-bootloader-xiaomi-t3831484 (remove [ ] again).
*Do the drivers update, flash only the critical and try again.
*If it doesn't work lock the bootloader with "fastboot oem lock"/"fastboot oem relock" and then unlock it again, flash critical and try again.
*If that failed try flashing the rom with the miflash tool (google it).
*One more thing you can try is to switch the partition: "fastboot getvar current-slot" if you get "a" back type: "fastboot set_active b", if you get "b" back type: "fastboot set_active a".
*If all failed I'd suggest you to lock the bootloader back and go with the warranty option. I bricked my mi a2 to a qualcomm 9008 state last month and couldn't get out of it without using test points to enter edl, so I just sent it back and got a new one right away for free. good luck!
If you have enabled 'OEM Unlock' setting in Developer settings, you will probably be good, you can unlock bootloader(oem/flashing/critical) and flash the official ROM ( as per now, 10.0.2.0 )
If not, you have 2 options
-Boot into EDL using short points and flash from there
Same thing happened to a friend's phone, it wasn't touched and just went brick after 10.0.2.0 OTA.
Guess everyone should enable 'OEM Unlock' in case this happens(Data Encrypted anyway, worst case stolen phone better than the chance of brick every time an OTA comes)
edit: If you want to save your data, you obviously shouldn't try the bootloader unlock way...EDL flashing allows flashing without wiping data, but haven't tested that personally
Thanks for the tip. Also I meant EDL flash... typoThat's a tough nut to crack, soo good luck !
Try to remove every sensor of the phone like: the camera , the vibration motor, the microphone and proximity ecc...
My Sony z3 had the same problem and at least after many attemps I discovered that the proximity sensor was broken.
