iOS 6 on iPhone 4

I got to downgrade an iPhone 4 to iOS 6.1.3 today. Below is the result from doing so, from iOS 7.1.2, and proof that it is indeed on iOS 6.1.3.

Ok, thanks for letting us know these are your own images. Did you get the old ipsw's from The iPhone Wiki? https://www.theiphonewiki.com/wiki/Firmware

No, just used another method. Just used ipsw.me to download the IPSW. The link to the method I used is below. If you want to try this, you will need a macOS virtual machine or a Mac (M1 Macs also work, and that's the type of Mac I used), and a GSM iPhone 4 (model: iPhone 3,1).

Thanks! Why only GSM? Would this work on a CDMA iPhone?

This doesn't seem to have compatibility with CDMA models, due to the slight variation in the hardware, as is the case with iPad 2s with an EMC of 2560 (iPad 2,4; 2012 model) compared to the 2011 model with an EMC of 2414 (iPad 2,1).

Ok thanks, it looks like some of this might be moot soon because all the phone companies are shutting down all the 3G and old CDMA networks next year anyway. https://www.theverge.com/2021/5/27/22457255/verizon-att-3g-shutdown-date
