iPhone 4s Upgrade. Error at line 13331. Transferring iBSS

Hi,
I have successfully restored an iPhone 4s to iOS 6 using 3uTools. Of course I want to go higher than this and the only other option I have is iOS 9.3.5 which is fine. However when I go through the Pro Flash stage, I get an error just after the 'Transferring iBSS' stage passes. Any ideas?

Error is 'Error at line 13331'
'Failed to flash'
Thanks

Ok, please check the network connection of your PC. Or try to Easy Flash on 3uTools, if there is still error, please kindly send me the screenshot via 3utools@gmail.com
