Hi,
I have MANN ZUG 5s i was using adb tool and tried to reboot device in bootloader using command
fastboot reboot-bootloader
but my phone got stuck, it will show fastboot downloading.... in black background. No matter how many times i restart it will get stuck in this screen. If i pull out the battery and put in again and press the power and volume down button it will go to recovery mode i tried to wipe date/factory reset nothing helped.
I tried to find the compatible boot.img file to flash the boot image in recovery mode with "apply update from adb" but it will fail with "signature verification failed" error. also tried to flash new ROM of another device(because i cannot find the ROM for this device) in similar way all fail with signature verification.
Any help is highly appreciated.
Regards,
Swat
