Yes
It is just as easy to any of the three:
1) Update using an OTA update file;
2) Flash the stock images using fastboot;
3) Flash a recovery-flashable stock ROM zip.
I prefer number 2.
Fastboot is an important tool, and users should get familiar with using it.
Yeah I use fastboot myself for flashing recoveries & stuff but why'd you flash the whole image with data loss if you can update by just flashing some zip files in recovery?
And for 7-zip, it extracts all files except for radio and bootloader. Am I doing things wrong if I just copy them to the directory with my fastboot files?
