CMF Phone 1 (Dimensity 7300) Hard Brick after switching slots. MTKClient shows INVALID\_ADDRESS. Need help!內容 (Content):Hi guys, my CMF Phone 1 is already Bootloader Unlocked. Recently, I mistakenly executed the fastboot command to switch the active slot to Slot B (which has no OS installed).Now the phone is completely black-screened, won't show anything, and cannot boot.What I've tried:Blindly trying to force into Fastboot (Power + Vol- or Power + Vol+ + Vol-) does not make it pop up under fastboot devices.Connecting via MTKClient: The PC successfully recognizes the VCOM/BROM connection and pulls the Target Info. However, when attempting any read/write or unlock action, it instantly errors out with:\[LIB\]: Error on da\_write64, addr 0x200900, INVALID\_ADDRESS (0xc0020005)DeviceClass - USBError(5, 'Input/Output Error')It seems the generic DA in MTKClient doesn't support the Dimensity 7300 (MT6878) memory addresses yet.Is there a leaked custom DA file (DA\_BR.bin / scatter) available for this device, or any other method (like physical hardware disconnect) to bypass this check? I am comfortable with hardware if needed. Any help would be greatly appreciated! Thanks in advance!
