If you're prepared to get out a soldering iron and/or chip-clip, you can usually back up and restore whatever IC stores the firmware you're modifying, giving you a recovery path.
> we also need good glitching tools
There are a lot already, what do you feel is missing?
- srcreigh 2mo agoHow 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.
- Retr0id 2mo agoThere are plenty of pre-2023 resources out there, especially conference talks. But, Claude has no issues discussing glitching if you have CVP.

- s3p 2mo agoI 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
- ShinyLeftPad 2mo agoIs 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.
- csh0 2mo agoI have encountered this behavior in people of all ages for as long as I can remember.
- ShinyLeftPad 2mo agoI haven't and neither my friend
- perching_aix 2mo agoAnd what are we supposed to do with the two of you apparantly living under a rock [0], and going through baby's first "kids these days" moments, exactly? Never heard of LMGTFY ("Let Me Google That For You")? Why do you think it exists? Or "Google / Wikipedia is your friend"? Or RTFM ("Read The Fucking Manual")? Really not new inventions (and "zoomers" were there for them, cause the oldest ones are pushing 30! [1]). Not hard to search for either, by the way... [0] or rather, going through some very conveniently selective amnesia [1] just to really give you a sense of how stupid this generation-xyz thing is, this "generation" includes people whose first OS was entirely possibly Windows 98, and at the same time, people whose first OS was Windows 10
- ShinyLeftPad 2mo agoI heard of them but have literally never seen any of those phrases on HN. Therefore I'm saying what I'm saying;) I saw LMGTFY link once maybe...
- rustcleaner 2mo agoLook, he doesn't know what to search for. He doesn't have your experience to know what is crap and what is good info, and the big models will ninny-nanny him for '''safety reasons.''' There is so much more shit to wade through today than a decade ago. Cut the kid some slack and be a mentor! Gatekeeping kills.

- Retr0id 2mo agoI'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.
- jwrallie 2mo agoI 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.

- MayeulC 2mo agoPlease 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. https://libreboot.org/docs/install/spi.html#do-not-buy-ch341a https://libreboot.org/docs/install/spi.html#do-not-buy-ch341...
