iPhone not working after 17.2.1 update

Update 17.2.1 installed last night and my iphone 14 has frozen. Touch screen does not work and attempting to restart it makes a call to emergency services. I can't attempt any of the solutions when my iphone wont respond. AAAARRRRRGGGGGHHH!

On the upside I can at least stop alarms using Apple watch.

• Press and quickly release VOLUME UP

     then

• Press and quickly release VOLUME DOWN

     then

• Hold the SIDE button until an Apple logo appears (15-30 seconds), ignoring "slide to power off" if it appears

The operative word here is QUICKLY; and try it a couple of times, the timing is a little tricky. If done correctly this will always work unless the phone has a hardware problem. 

Seems to be mostly T-Mobile.

Don’t have VPN and won’t connect to T-Mobile network. Or get bounced off after it works for a while. Very frustrating.

Same issue on T-Mobile. If I disable cellular and then turn it back on it will work for a while before failing again. The cellular signal is fine - 4 bars 5Guc.

Follow the guidance of the others in this thread who solved it by deleting their VPN.

Cricket is your carrier, and is unrelated to Wi-Fi. Here is general information on Wi-Fi troubleshooting→If your iPhone won’t connect to a Wi-Fi network 

The key things to check:

• Restart your router by removing all power from it for 15-30 seconds
• If you use VPN, delete your VPN profile and app
• Tap on the i next to the network name and Forget the network, then try reconnecting
• Open Settings
  • Tap General
  • Tap Transfer or Reset Phone
  • Tap  Reset
  • Tap Reset Network Settings
  • This will erase all Wi-Fi passwords, but will not result in any other data loss.

This mirrors my experience as well. T-Mobile's call-in customer support had no explanation or solution to-date.

At this point the phone has been reset/erased all content/removed from iCloud and reactivated as a new phone with everything at default and no third party apps installed. New SIM card was installed. None of that resolved the issue with personal hotspot, which had been working fine for a couple of years.

I was able to get my wife’s phone working again after she upgraded and lost cell service. I downgraded her phone from 7.2.1 back to 7.2. Then during the initial set up of the phone, we upgraded her to 7.2.1 again. For some reason, this time she was able to successfully upgrade and retain cell phone service. Downgrading meant that she had to restore from the cloud, reinstall all her apps, and set up other features again, but at least she has service now.

I feel that it's important to point out that there is nothing to indicate that Apple is monitoring these complaints, or is doing anything about them. I would suggest that if your problems continue, you get in touch with Apple Technical Support, who has spent hours with me running diagnostics to at least document the problems. And then ask to be sent to Customer Service to see what they can do to get you a working phone. Don't waste your time going to an Apple Store, as they can't fix the problem, and told me that they would charge me to repair my phone which stopped connecting to the cellular network immediately after the update.

You will notice that, except for some early success with people getting rid of VPNs, there is nothing in this discussion that solves these problems, or that indicates that Apple is taking any action to come up with solutions. If you want action, you need to communicate with them directly, and don't stop until you find someone who can help you.

I'm sorry but tired of how we pay for so much stuff that promises us the better life and yet it never works. He always always ducking with. It never works never better your life at all actually just makes it worse. I'm all these big corporations like Apple android well we didn't guarantee it it will give you a better life we just guaranteed that you could buy a product from us pretty much, I'm tired of this crap I'm tired of being guinea pig I wanna get paid for this crap I gotta test your **** out tell you about it so you can fix it because you didn't test yourself who with me on that many phones are broke. I'm just aggravation of the freaking phone that doesn't work like it supposed to hate it. I hate all technology know I'm gonna go with the canon string again.

I just got this work!!! Here is what i done step by step:

1. I created new appleID
2. Logout my main apple ID on appstore
3. Log-in new appleID
4. Download couple softwares using password then appstrore start asking faceID
5. Logout new appleID
6. Log-in your main ID
7. Download couple softwares using password
8. BOOM Appstore starts asking my Face-ID!!!

After two weeks. I’m using an old phone because my 13 pro max still won’t work. Here’s what Ive learned.

• It’s likely an Apple issue. Not the carrier.
• Apple says it’s a carrier issue. Verizon says it’s an Apple issue.
• Mine is strictly cellular service dropping resulting in an exclamation point in a triangle where the service bars are. WiFi still works.
• Has anyone determined if it’s only affecting 5G phones?

Last night Apple tried to do a hard push for the 17.2 update on another phone of mine which maybe they did with many others. This might help us by having more people with the same issue.

Deleting the VPN and profile has no effect - phone still won’t connect to TMobile network.

This is exactly happened with me today. After iOS 17.2.1 update my iPhone 13 Pro failed to connect to a cellular network

Nothing, still no cellular connection! Apple Genius Bar rep quoted $549 for repair!! Pathetic…

Possible solution

Verizon customer. After 3 trips to the Verizon store, new sim cards, Apple tech support saying it’s a service provider issue then Verizon says go to an Apple Store which is over an hour away.

I connected to my computer, opened iTunes. Of course it won’t update because the most recent update caused the problem. I did a complete reset, wiped everything and started from scratch. Make sure you have wifi. At one point I got the attached picture I connected to my laptop and iTunes and through a series of trying every option I think I fixed it. At one point it said I needed an update which then did it over wifi. 12 hours with service and it’s so far good
