Prompt [Q] Downgrade from GPE to 4.3

Someone can help me downgrading my MOTO G with unlocked bootloader from GPE to stock 4.3.
I've been trying but I get "Image is too large" when I try to flash "system.img".
I want to downgrade to stock 4.3 Claro Argentina firmware.

Please, I really need your help!

Could be two things:

1. You may need to flash gpt.bin from 4.3 (included in official 4.3 download) as this will create a new correctly sized partition table.

2. Make sure you use motorola fastboot to flash (known as mfastboot) and not the Google fastboot.

And follow:

fastboot flash motoboot motoboot.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img

fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache

Unfortunately i'm in the same boat, stuck at boot. Flashing different zips doenst seem to help. I think the partition has changed since the 4.4.4 OTA from 4.4.2 on the GPE. It's impossible to flash a different rom at the moment. Hopefully there will be a fix soon.

same problem here. I was able to fix my phone partially with
1, factory reset in recovery (twrp)
2, adb Cyanogen rom
3, fixing reception with
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
using gpe 4,4 fsg

DONATE TO ME
Is fastboot mode available? If yes then you could just either 'dd' them or flash via fastboot, starting with sys partition. Don't touch the efs.
