Restore error 14 or 1671 after inverting screws

Hi guys,

I replaced my screen once, and I think I may have damaged it while replacing, by forcing it too much. Anyway it doesn't mind.

I thought it could be the screws position placed wrong here:

Then, I opened the phone again and inverted the screws position, putting the bigger on the smaller place, now the phone was damaged I think.

Tried to turn it on, had that blue screen and then the boot loop.

I put the screws back to the original place, however the screen was gone (tested the old screen and it was working) and the phone is on DFU mode: I cannot get off it

When I try to restore i have error 14 on my pc. One of my mates got error 1671 as well.

I tried to restore it by many ways, but none successful. One thing that I didn't try yet was to restore on a Mac, but I don't think I will able to revive the phone by doing this.

The question is: is my phone damaged and gone (as the logic board is too expensive) or is there any chance to get it back?
