Reconstructing Device Firmware From SPI Reads No comments by: Tom Nardi September 24, 2026 Title: Copy Short Link: Copy If you wanted to extract the firmware from a mystery device, you might pull the flash chip out of it and toss it into a reader. But if you only had one chance to get it right and couldn’t risk damaging the device in the process, physically removing the chip may seem much less attractive. Reading the chip in-circuit failed — because of course it did — so what does that leave?

But if you only had one chance to get it right and couldn’t risk damaging the device in the process, physically removing the chip may seem much less attractive.

Well, if you follow the example of [Matthew “wrongbaud” Alt], the next tool you reach for might be a logic analyzer.
