iPhone 12 will not update after battery replacement
I changed the batteries on 3 iPhone 12's using good quality batteries from. 2 of the phones will not update to the latest IOS.
Because of the square edge design of the iPhone 12 and the new glue being used, I was concerned about how I would get the screens off without them cracking, so I heated the phones up to 90 degrees, used a pry tool to get the screen out of the frame slightly and then used Isopropanol to degenerate the glue.
I did not disconnect the screens when I did the battery replacement.
Could the Isopropanol be trapped in the phone causing some issues or is this because of the battery, which I doubt. The third phone seems to be ok.
Ist dies eine gute Frage?

I just have a few questions
Does it work if you update using iTunes and/or 3U tools?
What version of IOS are they on
Do you get an error of any kind
Have you confirmed they are not blacklisted
Is baseband working/does the IMEI show up in settings

Hi Sabastian, thanks for the help.
Not tried via iTunes or 3U Tools. Did not have this problem before the batteries were replaced.
They are trying to update to IOS 16.6.
Error message says "Unable to verify update"
They have tried updating at a different location to eliminate the possibility of it being slow internet connection.
I can not imaging why they would be blacklisted, they are not short of cash and these are phones used for a business.
Will get the other answers shortly.

The answer to the 2 other questions you had are:
The IMEI is visible
The current IOS is 16.6, which is strange, but...
I think I may have uncovered the issue. This person had Beta Updates switched on. Beta updates were then switched off for this update. The phone is showing IOS 16.6 installed, but still wanting to install 16.6. Could it be that a 16.6 Beta version is installed and now that Beta updates have been turned off, that the phone is trying to install the 16.6 version which is not beta, but it is unable to as a 16.6 Beta version is installed.
