I have seen many iphones worked after activation eventhough *#06# doesn't show imei on screen but you can find it in the setting. In this video, I could see IMEI is ending **8811 that is 13 pro.

[@PhoneRepairRO]

If IMEI does not show when you dial *#06# and you update/restore, the phone will not activate! Watch entire video, the phone had oxidized pads and lots of disconected pads!

[@staray7541]

​@@PhoneRepairROthank you for quick respond. When dialing *#06# doesn't work I get imei number in the setting and activate the phone. I am just curious why #*06# doesn't show number but imei is in the setting.

[@PhoneRepairRO]

@@staray7541 If IMEI shows in settings and you are able to activate the phone it might be some power line that is shorted (and/or disconected) and not related to Baseband cpu, but related to some I2C line, some power amp and so on! There are alot of parts not related to Baseband cpu / eprom that can mess with some I2C line. The phone will activate but no IMEI when dial *#06#. I actualy have an iPhone 13 with this problem, i swaped RF board and the problem is still there! I will swap the AP board soon (it will be a long video about this one).

[@staray7541]

​@@PhoneRepairROit has been bothering me for a few years. Thank you so much.

[@fixthisone]

This happens when the modem power section works but there is an issue with one of the power amplifiers. All the *#06# does is test quickly if all the network circuits can be pinged and respond

am having dsame problem on my iPhone

[@PhoneRepairRO]

Hello, If the phone was dropped, you will have some broken pads! On these models the solder is more rigid, so it will rip apart the pad from inside the board! If you don't have microsoldering skills, i recommend you to go to a shop that can do that for you. Have a nice day!
