I have accidentally secured a MK70FX512VMJ15 device. I was trying erase flash block command and i have accidentally erased program flash memory at address 0x00000000 where are stored configuration fields.


Now i'm not able to download source code from IAR Embedded Workbench because it shows a message telling that device is in secured state. It asks me to make a mass erase but it seems to fail (it shows again and again the same message).


I've tried to use Jlink.exe command line to unlock device. Unlock command seems to be successful but, if i try to download source code, device is still secured.


Do you think is it possible to unsecure my device?
