iPhone 7 baseband problem
Please help. After repairing the audio system on the iPhone 7, the phone lost its network. He stopped showing the IMEI number.
I was able to desolder the baseband and clean the main board from the remaining glue. Many solder pads have been removed, but these are NC fields.
I have obstructed the system twice and, unfortunately, the IMEI number is still missing, the phone has been uploaded and 3utool displays error -1 at 80%. On one forum, someone said that he sees the problem in the picture, but he does not want to provide information on what the problem is. Thank you for your help.
Unfortunately, there are so many servants in Poland who are happy with someone's problem.
I have checked the capacitors and have no short circuits.
On the voltage coils as in the attached picture.
Thank you for your help, I do not hide that I did it for the first time and it would be nice if the phone started.
Is this a good question?
