However, we have prepared 5 ways to fix iphone firmware not compatible for you, and you can try them out, because you will probably solve the problem.. Okay, so my girlfriend uninstalled something necessary to her 8.4 jailbreak. because it was messed up, i updated it to 8.4.1 like an idiot, hoping i could downgrade. i can't downgrade because itunes keeps telling me the firmware's incompatible. so what the hell do i do? because i've tried 2 different macs already.. Want to downgrade ios 9 back to ios 8.4.1? you can do that, as long as you move fairly quickly. if you have an iphone, ipad, or ipod touch that has been updated to ios 9 and decided it’s not for you for whatever reason, you can revert back to the prior release. maybe you felt the update runs slower, maybe a necessary app isn’t yet compatible with the new ios, or maybe you just preferred.
Please help when i shift click to check for update i select the right firmware and its say firmware not compatible i have an iphone 5 a1429 please help !!! i tried too with dfu mode. Although you can’t fix this issue while staying on this firmware, you can still go back in time to ios 8.4.1. downgrading to ios 8.4.1 from ios 10.3.3 has several advantages. firstly, you will have significantly better performance. secondly, you will still be able to jailbreak your device and run cydia tweaks..
