Resetting to stock ROM

Assuming the ROM you are flashing have system.img_sparsechunk file starting at 0 and ending at 10 we have:

fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash radio radio.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk1
fastboot flash system system.img_sparsechunk2
fastboot flash system system.img_sparsechunk3
fastboot flash system system.img_sparsechunk4
fastboot flash system system.img_sparsechunk5
fastboot flash system system.img_sparsechunk6
fastboot flash system system.img_sparsechunk7
fastboot flash system system.img_sparsechunk8
fastboot flash system system.img_sparsechunk9
fastboot flash system system.img_sparsechunk10
fastboot erase cache
fastboot erase userdata
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot

If the ROM you are using have less or more system.img_sparsechunk just adapt, also make shore to check if it start at 0 or 1 as some stock ROM have that diference.
