I was not expecting data to be transmitted on the pin. I thought the boot select pin was an input. What kind of chip is the header connected to? Do you still have the capture of the waveform saved? Do you know if the third pin is connected to anything? I am sorry that I can not answer the questions myself. I don't have the device. |

No, this is what I have. The photos show which chips are on the PCB. The pin that stays low might be an input, but on this multilayer PCB, I can't trace where it leads. Additionally, I don't want to risk damaging the board by randomly applying voltages to these logic inputs with a multimeter. The potential for damage is not worth the risk to me. I am already far outside my comfort zone with this scope disassembly. It’s brand new, and I still remember what I paid for it. Initially, I hoped to establish a connection with the CPU via a JTAG interface so that I could create a memory dump. After that, other experts might be able to generate the keys to liberate this scope. But unfortunately, the CPU doesn’t appear in the JTAG chain. I think this is where it ends for me, and I’ll just put everything back together neatly. |

It seems like that although firmware 0.9.5 uses a brand new key system, but it can be directly downgrade to 0.9.3, then use some python stuff and upgrade back to 0.9.5 or higher. But the latest firmware 0.9.9 disabled firmware downgrade... so... :-BROKE |
