Yes, you can resolder with hot air also. Just buy a flux pen. Make some flux to the solder pads, put eeprom on pads, and make it hot. The eeprom will swim to the right position. Buy a good station, where you can set the temp. Otherwise your can overheat eeprom and pcb. Make training with some old pcb´s.

the problem is the risk of corruption. if you lose the dump you are in a world of hurt. safer to desolder & only takes 5 minutes anyway
personally, I always desolder, sometimes, once ive got the dump & will try to read in circuit so I know for next time

I've already tried it on vw cluster but it didn't work because dump read was wrong. Desoldering E2P is always the safest option and must always work
