As an atheist, I ask for prayers that the backup's good.
E: Your solidarity has worked. The backup is good and not too old. Note for myself and you - install your OS on a snapshotting filesystem so that live backups are possible.
Thats a good advice, for that to work you just need to remove the solder, reball the memory ic and solder back if there are no broken/ripped pads. If there are any ripped pad then still can be done but you need an expert at microsoldering to rebuild the tracks
