I got and old kindle 8th gen (SY69JL) for free, 'cause it couldn’t connect with any wireless network. I tried to do the bridge for popcorn hack as seen here (https://kindlemodding.org/jailbreaking/Legacy/Popcorn/KT3.html). Stupid as I’m, I used the 60w solder and I thing I ripped one of the pads. The damn thing doesn’t turn up (not even the led) or shows at lsusb. Is this now just an e-waste? It gets a little warm when puggled on the usb.
Given how your first mod went, I’m going to suggest you use something decidedly less aggressive than a dremel. Leave the power tools on the bench for this one. A simple hobby knife or sanding stick will get you there just fine.
yeap, a little to rough there :)
