Hii ,
I have desoldered a flash IC and put it in TNM programmer and tried to read and dump the firmware ,but i could not get any information .the output is shown below

what might be the reason for above output? i dont think firmware seems to be encrypted??

 

Did you use hot air to remove it? Maybe it got hot enough to erase it?

 

Most likely the chip read-protection has been activated.

i have few doubts
1) when we power on a circuit board ,first control goes to bootloader and according to instructions written on the bootloader ,it will go to flash ic or some other parts right??.
2)If firmware is stored in flash ic and it is encrypted means ,where will the private key be stored and can we get that private key to break the security? please correct me if I'm wrong.
