iPhone not working after 17.2.1 update

Interesting. My experience with the t-Mobile Store was that they had no explanation or solution. They couldn't get the cellular data connection to work. Now the phone seems to have dropped down to an Edge connection, but still no data is getting through.

Perhaps the update did result in damage to the device. That would explain a lot.

That might be because T-Mobile stores have no qualified techs in them, only sales people, just like Verizon and AT&T. For T-Mobile and any other US carrier you are better off calling to speak to tech support than going to a store, and asking the CSR to escalate your issue to a real tech.

What worked for me was …. I changed 5G auto to LTE

i did this after going through the motion of resetting settings etc etc

(same thing we all did - everything and it did not work )

once i put it to LTE … it started working

My 12 pro max like I reported before was shut down for no reason .

I bought a new 15 pro max and work very well .

regarding the 12 I just changed the battery settings for not be optimized charged 100 %, and battery now works very well.

and my 12 never shuts down again.

After destroying my old SIM card and installing two new eSIM cards, my phone is able to reconnect to TMobile network again. Fingers crossed that third time is a charm. Apple support seemed to have no clue, and seems to knee jerk wiping your phone clean and staring all over. Not necessary if you get a new eSIM that works.

Finally after hours of reseting my iPhone 12 Pro, I got hotspot working. Here's what I did, I have 2 Mac mini's I had to go into network setting on my Mac mini's goto your wifi connection then go to advanced under advanced where it says Network Name select iPhone then I went to TCP/IP and pressed Renew DHCP Lease. That's it, I did that in both my Mac's and my Hotspot is back up and running. I don't have any of the other issue others are saying. I also turn on my VPN on my Mac's and it still works.

So the real question is, is there a reason for us to sit and complain here? Would Apple really fix this or they just watch us complain? I’m new to this. I’ve had this issue for 11 days now.

Apple is not watching you complain. This is a user-to-user forum, and only other users are watching you complain. If you want to hear from Apple contact Apple support; you can click on “Support” at the top or bottom of this page.

Or you can read the thread you posted to, and see how others have dealt with this symptom. Or both.

Since updating to 17.2.1 my phone is over heating, contacts on my phone will not show up when searching by name, every call takes 30 seconds to connect, and a lot of the functionality such as clicking enter on a page will not work. Can this update be uninstalled? Will this solve the issue?

Apple can’t address an issue with YOUR iPhone without diagnosing it. Believe it or not there are over a billion iPhone users who do not have this problem. The problem is with your phone or your carrier, not Apple. Have you contacted your carrier about this issue?

Went to T-Mobile today, and talked to several associate's ask them about iPhone iOS issue's with 17.2.1, everyone said they haven't had any customers with iOS update issue, I have a iPhone 12 Pro except for the problem with the hotspot issue which I solved, I'm not having any of the other issues which others are reporting. I know iOS 17.3 is still in beta and is due out sometime next month. When iOS 17.3 comes out I'll hold off on updating until I know that these issues are solved.

My iPhone 12 Mini on T-Mobile has no signal issue, however there an issues with Personal Hotspot. I can't connect my Galaxy Watch 4 to my iPhone after updating to iOS 17.2 and up(17.2.1) . Watch says: IP configuration failure. I couldn't downgrade back to 17.1.1, all I could install is 17.2 which wasn't good either. ****

I filed feedback with Apple.

@bobotompa,

This worked!

Since Apple is still signing 7.2, I was able to revert. Problem solved.

I am not so brave as to venture back into 7.2.1 territory after a week of utter frustration though.

I think I'll opt for the next major release instead.

Thanks...

Thats normal, its because 5g isn't available everywhere yet. Depending where you are depends if your phone goes to 5g or LTE. My phone does the same thing. Its normal, itll get better as the years go on.

17.2.1 isn’t working.

maps deleted all my favorite files

screen freezes up

both WiFi & Cell w/roaming isn’t connecting

no app updates

great job on the updates.
