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.

You need to change the battery for an apple approved battery (oem)

Also you can check your itunes version and make sure it's up to date, worth a check but i'm betting it's the battery

If you saved blobs for other ios firmwares there isn't being sight at the moment,

you should be able to up and downgrade to the ios you saved blobs for.

Update iPhone with iTunes but get iTunes error 29? For this problem, if you have a backup, try to put the iPhone into recovery mode and connect it with iTunes to restore it. If not or you still get this iTunes error, it is suggested that you use Joyoshare iOS system recovery software. It can fix many iOS issues and iTunes errors without data loss.
