fastboot too old problem

If you want to perform stock factory flashing of a Nexus device and you encounter “fastboot too old” error message, that means you need to update your local fastboot application to a newer version. One additional word would make this interesting error message self-explanatory..

Google Android Nexus Device Un-Brick

If you happen to brick your Google Nexus device you can always use stock ROM images [1] to revert it to a default and operational state. Package contains not only OS but also bootloader and radio firmware images!

I have bricked my device by installing custom firmware that messed partitions layout inside a Flash Memory. I have seen lots of people having similar problem of endless bootloader-loop. There is no need to send a device to a service when bootloader is operational. All you need is a stock firmware image from Google [1], USB cable, and fastboot utility from Android SDK. If you happen to damage a bootloader, then hardware manipulation at low-level is necessary over JTAG, I can help to recover your device in that case.. no worries :-)
