Jailbroken iPhone 4S, stuck on iOS 6.1.3 HELP!

[jigsawsaw81]

I bought i refurbished iPhone 4S just to use it as an iPod, and cause i love the design still even in 2019.

I downgraded to iOS 6.1.3 from iOS 9 the very day i got the iPhone, and it was fine.
So the issue is, the refurbished site must have replaced original battery or something.
Every time i wanna flash iOS 9 update again, its giving me itunes error 29.

So, is there any way i can flash iOS 9 Signed ipsw without using iTunes or, using itunes but without any error? any solution?

I jailbroken my iOS 6.1.3 too, in case it helps.

Also, can i flash any unsigned ipsw as am jailbroken, possible?

Please tell me a possible fix! Thanks.

I have read that replacing the replacement battery with an OEM one might work.
