In layman terms we can say that Fastboot mode is a maintenance mode that is built in the phone for upgrading and diagnostic purpose. This mode is for developers, but if you think you are okay with fiddling with your mobile phone. You should access this particular mode. You can only install firmware, however there is a neat trick. It allows you to access other system modes, but first you need to know how to get into the fastboot mode. Even if you want to get into the recovery mode, you first need to get in the fastboot mode.

The owners of HTC U Ultra can also enter into fastboot mode on their devices with the following easy-to-do guide for turning your phone on into fastboot mode. The best thing is that you don’t lose your warranty if you boot into this boot. But flashing firmware that are not authorized by HTC will make you lose your warranty. So, we highly recommend not messing with your phone when you are not good with Android protocol layers and computers.
