To solve software problems such as being stuck on the logo due to incorrect flashing, bootloop due to wrong firmware, or wanting to return to full factory settings and other software issues,
The firmware we share comes from official sources, although Firmware27.com always recommends testing and backing up before performing the flashing process.

How to flash NOTE 40 Pro+ 5G X6851B

For flashing this type, special tools are required and they may be paid. We have tried free tools and failed; they are not able to bypass the security. Use CM2MT2, TFMTOOL, AMT, or other supporting tools.
Example using CM2MT2: Open the tool, select the brand Infinix 2023-11, click Flashing, Open File, select flash.xml inside the firmware download_agent folder, then Flash. For the boot button, hold both volume up and down, connect USB while the device is off.

Bypass remove frp NOTE 40 Pro+ 5G X6851B

Still using the same tool, click the service tab, check FRP erase,
press the boot button, hold volume up and down, plug in USB while the device is off
