iOS 14 has a kill switch for my iPhone 7

[Ggvfvgbffbf]

3 year old iPhone 7 (bought new from Apple when the 8 came out). Replaced the battery (through Apple) 18m ago. Battery reads 88% capacity. Otherwise perfect condition. Was slowing slightly under iOS 13 but understandable and still fully usable.

Left it to install ios 14 on Wednesday night and it was bricked in the morning. Completely unresponsive. DFU restore powered it up, but after the firmware was installed it said ‘your iPhone will now restart’ but never did. Did it several times and the firmware installs but it is then unresponsive. Will not power up to the ‘hello, hola’ screen.

Long story short, downgraded firmware to 13.7 whilst it’s still being signed. iPhone works absolutely perfectly. What gives?

(Out of interest my iPad Air 2 had no problem at all upgrading to iOS 14. An absolute tank)

Sounds like an installation that went bad.

No, tried it multiple times via a clean restore.

My 7+ upgraded to 14 fine. Same generation. My SE 2016, older, slower, upgraded fine too.

To the original poster:
Similar battery health (87% Iphone 7+) and IOS 14 drained battery in a couple of hours. Downloaded 13.7 firmware ISPW file quickly while Central KONTROL in Apple allows it and rolled back the OS. Tough job restoring data (stupidly I did not back up before automatic update to 14 which is now turned off forever) and all apps reinitialised (what is the point of Apple backups?) so bit of a pain but at least my phone works as it should. WILL NEVER BUT ANOTHER APPLE EVER AGAIN. You can find instructions on Youtube for rolling back.

Thanks. I took it to where I bought it from (Apple, Trafford Centre, UK) and they were useless and more interested in taking people’s temperatures and keeping customers outside the store. They hooked it up to a laptop and basically said the hardware has failed (coincidentally at the exact moment I installed iOS 14) and to buy another. I knew that was bollocks so rolled it back to 13.7 like you and it’s absol fine now.

I did some research around the web and it’s been suggested that a major iOS release (13.0/14.0) will write to different parts of the phone’s memory. If parts of that have failed then the phone will not work on the new firmware but will work on the old firmware.

It‘s poor from Apple though. Most people haven’t a clue how to install old firmware. They’d have tossed the phone in the bin after being told to install the software update by... Apple.

It would also be nice if a mini-computer costing £700/$900 could last longer than 3 years.
