I installed ios 14 on my iPhone SE(gen1) and i can’t set it up (“an update is required to activate your iphone”) + it does not have an IMEI number. The phone have marks of waterdemage, from before i bought it.

  1. Start the Settings app.
  2. Tap “General,” and then tap “About.”
  3. Scroll to the bottom of the page, and you’ll see the IMEI number.
  4. If you want to record the IMEI number error-free, tap and hold the IMEI number for a second or two until you see the Copy bubble appear. Tap “Copy” and you can paste the number into another app.

Phone need to be repaired that issues is related to Baseband circuit….so take it to technician it will be fine if baseband CPU and baseband EEPROM are
