Hi, Recently i have upgraded to the nexus 6 and i nolonger use my old moto G gen 3, I was going to sell it for some spare cash but i cant get it to flash and lock the bootloader with stock firmware, ive been at this for a couple of days and all the forums i have read (i looked at as many as i could on several different sites) i couldnt find the answer as they will come with the issue and it would never be resolved. On to the issue;

 

this is what i have been using to attempt to reflash and lock my phone, yes i have tried mfastboot aswell.

 

adb reboot-bootloader

fastboot oem lock begin
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.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_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1 
fastboot erase modemst2 
fastboot flash fsg fsg.mbn
fastboot erase cache 
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot oem lock
fastboot reboot

 

what seems to be the problem is when i do a "normal" flash of the stock rom everything works though if i try to lock it the system fails

its ok, the moto g 3 is a tricky phone to mess with, ive had allot of phones rooted flashed ect and its mostly straightforward though this has proved to be the complete opposite.
