De acordo com o comentário de @AaronMiller no post original:
It's not feasible to repair the wrecked SD card slot; in order to do so, you'd need to disassemble the Chromebook, desolder the destroyed part, disassemble that, and bend the pins back into shape, and if you can do that, you can much more easily order a PC-board-mount SD slot of the same form factor and just replace the broken part entirely. Much more practically, why not use a USB SD card reader? It's not as streamlined as an integrated one, but it'll work, and will be easy to replace in the event that whatever happens to the integrated slot happens to the USB reader too.
