"Error -1" when reinstalling iOS, most likely

Question

OK so I had issues with the phone losing network and decided to reinstall iOS (was 11.4 before reinstall, iPhone 7). When reinstalling with Restore in iTunes, I've received (-1) code, which leads to baseband chip according to Google. Also tried restarting with iMazing and it fails on a step related to baseband...

I've already tried multiple restarts, recovery, DFU mode. While searching for the solution with thinking of where I'll be able to get some loan for a new phone I've found a workaround with heating the device while restoring with a hairdryer! Wanted to ask if someone heard/used this method and if yes (and it's not a trolling) should there be any issues with 7 and what should I be aware of?

Side question: any sense/chance to replace it or seems I'll have a new phone soon?

Edit: This is a second-hand device, and I'm in a country where replacement program for A1660 doesn't work (just called to Apple authorized service).

Assuming you have an A1660, apple has a service page for help. If you take to an apple store, they’ll ship it to their depot and replace the motherboard.

Considering that you can't send it to Apple, I'd go for a reputable third party that can do microsoldering (bonus: You'll also get it repaired properly, with jumpers to keep the issue from reappearing). I'd personally ship it to iPad Rehab, which I can personally vouch for having great service and being able to fix the issue.
