How should I learn more about how to do it, what to buy, etc ? I haven't found ChatGPT to be a good teacher about this topic, and in particular re glitching, AI will refuse to discuss specifics
I have enough basic soldering to get UART attached, but not sure what to try after that.
Equipment-wise, I currently just have a few ESP32-C3s and electronics basics kit and some basic soldering stuff.
I flashed coreboot on an x220 once [0], and I think that can give you a good overall idea of how backing up and reprogramming an SPI memory works. From that you could do your own research checking the ICs in your hardware, and extrapolating to the correct tools you will need to read/write the chip you have in mind.

ch341a programmer with a clip attachment. That's basically it. A 10 USD investment. No soldering unless flash chip is SMD.
Please make sure you fix the 3.3 V output if you get that device. Most revisions have a PCB layout issue that will output 5V even in 3.3 V, which has bricked stuff before. There are many ways to fix it, one trace cut and one jumper is how I did it.

I think all of them sold nowadays have this fixed but yes, absolutely worth checking.
There are plenty of pre-2023 resources out there, especially conference talks. But, Claude has no issues discussing glitching if you have CVP.
I guess this is a fine reply but just seeing your earlier comment, mentioning there are tons of glitching tools out there, I would've hoped to hear about some specifics here. Just my 2c
I'd be listing tools all day, it's not worth naming anything specific unless a specific target / use case was named.
If someone said "we need good package managers", I'm not going to randomly start listing package managers without knowing what distro and/or programming language they're using.
Is this the zoomer syndrome I am hearing about lately? My friend says zoomer coworkers increasingly start asking easily searchable questions, and also (this part is not your comment, just my 2c) in a demanding tone like you owe them money. Allegedly they spend all their time in LLMs and lose the ability to gather information
I wonder what humanity will look like in 20 years if this doesn't stop.
