The same nrf52840 chip, after the successful attack, dump out 0-100000 and Dump full flash, get two bin file, by comparison, the difference is very big, and both files are not 1024Kb.
in addition there is another problem, I test in the G913 keyboard, after the attack is completed and dumped the firmware, the original keyboard use problems, manifested in the use of the Ghub to switch to off-board mode and the keys fail.
