What happens after Unbricking a Oneplus 3 There are many guide to unbrick the oneplus 3 and I followed the  [GUIDE] Mega Unbrick Guide for A Hard Bricked OnePlus 3 on xda by Naman Bhalla and after the step 9 this is my condition now
 i cannot access the recovery mode (but i can access the bootloader). when i try to access recovery mode a page appears that has its its first line as follows

start do md5 checksum.

then the below lines appear in red

cache : failed.
boot : failed.
boot_aging : failed.
system : failed.
md5 checksum failed.

when i try to upload oneplus stock rom through command window it says

archive does not contain 'android-info.txt'.
archive does not contain 'android-product.txt'.
error: update package has no android-info.txt or android-product.txt.

And one more thing ,I think i reached this glorious stage during a supersu unroot.WILL his lead to any more complications?

Please help. Being like this feels like forever. I am living in India so the chance of someone else knowing anything about this are very slim.

Thanks for the help in advance.
Since you're able to connect to bootloader, you need to flah the stock recovery then flash the stock firmware. This tutorial explains it better.

Go here to get Minimal ADB and Fastboot. Open it and run commands. You must CD to the folder containing the files to be flashed. Exemple: CD C:\Downloads\my_stock_firmware
and tape commands from there.
