What are you trying to accomplish with flashing the GPT and bootloader, and what happened to your device?

Is your device bootloader locked or unlocked and did you use the OTA update to the soak test Oreo build that's on XDA?

Can I see a screenshot or copy paste of the actual error that's reported from the ADB/fastboot terminal?

Fastboot bricked

Which blankflash files are you using that are causing this error, the September 2017 or June 2017 ones?

You may wish to try the December 2017 GPT and bootloader files : https://drive.google.com/open?id=1IfAX7v94ooB5wS7KTJGNYfQ2kXkHxP80

If the December 2017 GPT/bootloader files work, then you will want to re-flash the NPJS25.93-14-13 stock ROM (mainly for Brazil, India, EU and UK users, may flash onto other region's devices) to fully repair: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138

My moto g 4 plus XT1643 was hard bricked due to downgrading and then installed OTA update . So i used blankflash files June 2017 , but since then i am unable to any flash gpt.bin or flash boot loader . please help me here .

If you only had the stock Nougat firmware (especially the April 2018 NPJS25.93-14-18 firmware) flashed to your device, please try the April 2018 security patch GPT and bootloader from here: https://drive.google.com/open?id=13AuJkn8eelq-wQ5wp7lNQTf7kT7_lLwI

Afterwards, I would strongly recommend to NOT use OTA updates until you have flashed the NPJS25.93-14-18 firmware from here: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 You do not have to relock the bootloader, but if you do not flash the same firmware as your GPT/bootloader, you risk hard bricking, particularly if you downgraded. A main reason of bricks in this manner is because you don't downgrade your bootloader whilst downgrading; when using OTA updates, you run the risk of overwriting your newer bootloader with an older version, which is what causes the hard bricks. Thus, by flashing the same firmware version as your GPT/bootloader, you reduce the chances of a hard brick since your device is all on the same firmware.

If you used the Oreo soak test OTA at any point, I don't know if we can rescue your device at this point - the above GPT/bootloader may not work. The currently available GPT/bootloader files are only from Nougat stock firmwares. There is currently no Oreo stock ROM firmware and as such no GPT/bootloader files for stock Oreo/devices updated to stock Oreo. You won't be able to flash GPT/bootloader files onto your device older than your current bootloader as you've found out.
