Your phone is currently connecting in Diag Mode, which is why the process is not proceeding correctly for FRP operations. For proper FRP removal, the device must be connected in BootROM Mode. Only in BootROM mode the tool can properly initialize the device at a low level and perform the required FRP operation successfully.
So, please ensure the device is detected in BootROM mode first, then proceed with the FRP process. Once it is in the correct mode, everything will work normally.
