Does anyone have any idea what the difference between

iPhone6,1_8.3_12F70_Restore.ipsw & iPhone6,2_8.3_12F70_Restore.ipsw

I have a A1533 5s model and I'm on Verizon Wireless. If you look at the bottom of this page you'll see:

iOS 8.3 (iPhone 5s GSM): iPhone6,1_8.3_12F70_Restore.ipsw
iOS 8.3 (iPhone 5s GSM+CDMA): iPhone6,2_8.3_12F70_Restore.ipsw


Wouldn't my 5s use the iPhone6,2_8.3_12F70_Restore? 6,1 is GSM and 6,2 is Global. I just figured CDMA and Verizon? Someone has to know which one is the correct one for me to use.

I know I can just go into iTunes and click Restore and it'll download the ipsw but I think I'm getting the wrong one. If anyone with a 5s with iOS 8.3, on VZW & in the States could please tell me what ipsw file downloads for them I'd appreciate it.

Thanks

The correct one for your needs is iOS 8.3 (iPhone 5s GSM+CDMA): iPhone6,2_8.3_12F70_Restore.ipsw.

AT&T and T-Mobile use the GSM-only file. At any rate, iTunes would let you know if you had the incorrect firmware file.

I just did Shift+Restore in iTunes, added the iPhone6,2_8.3_12F70_Restore.ipsw and it wouldn't work? I get "This iPhone could not be restored b/c the firmware file is not compatible." When I select 6,1 it works with no issues, this makes no sense to me?

Hmm. I guess I was wrong. The other file was probably for Sprint customers, then. Sorry about that.

Glad you got it updated, though.

I have shamed myself.

You were not wrong. I just looked it up on multiple sites that host .ipsw files and 6,1 is for the 5s on GSM (AT&T and T-Mobile) and 6,2 is for the 5s on GSM+CDMA (Verizon and Sprint). I did find one site that accidentally transposed the numbers. I'm guessing that the OP downloaded the ipsw from the site that labeled them incorrectly.

The sites aren't wrong. I downloaded the ipsw from several respectable sites. Check for yourself and you'll see that iPhone6,1_8.3_12F70_Restore.ipsw is GSM and iPhone6,2_8.3_12F70_Restore.ipsw is Global. I could give you a list of all the sites. Even iTunes downloads iPhone6,1(GSM) when I do a restore. This is why I'm confused. iTunes wont let me install iPhone6,2_8.3_12F70_Restore.ipsw.

That's exactly what I just said - 6,1 is for GSM and 6,2 is for Global (GSM + CDMA). I checked four sites last night and they listed it as that. I found one site that had the 1 and the 2 transposed. Additionally, I tested it myself by checking what version iTunes would download for my GSM AT&T 5s and it downloads 6,1.

You have Global if you have a Verizon phone. I have no idea why 6,1 is working for you. It shouldn't. It should only allow 6,2.

Should I call vzw or Apple to get this settled. How am I using a gsm phone on verizon?
