Check out this from Formlabs: > [@Preform 2.5 Firmware Update Frozen?](http://forum.formlabs.com/t/preform-2-5-firmware-update-frozen/8969/4): > > Hi Mitch, indeed there are possible issues when upgrading firmwares on the Form 1+. You don’t need to worry about upgrading your firmware, PreForm will notify you if the Form 1/Form 1+ firmware needs to be updated. I am going to go into a bit more technical depth to explain what is going on, and why this part of the process has always been a bit dodgy. When upgrading the firmware on the Form 1+, the printer temporarily gets switched to a “DFU” mode, which means it now accepts the new firmware … Hopefully you do not have to wait until tomorrow to get back printing. --- _[View the full topic](https://forum.formlabs.com/t/crap-fw-update-is-completely-hung/9603)._
