It's not "normal" for it to stop working after you mess with it unless something went wrong either physically, or with the software you were using. However, it could always be coincidental that it stopped working as it DOES happen.
Thanks,.. yeah I'm thinking this might be a coincidence, I have another slim thats the same, and that drive had definitely stopped working long before I opened it up.
All I did with this was extract Dummy.bin, then I stopped and closed Jungleflasher, so the drive is unaltered I assume.
Someone please correct me if I'm wrong on that, thanks!
