iPhone 7 dead after removing Baseband CPU

Hi guys, I have a dead iPhone 7 here. It was repaired by other shop before coming to me. It was a poor repair by someone. They tried to remove the audio chip but failed. I can see they used lot of heat trying to remove the audio chip and shorted it underneath. Knowing the cause of the short, I swiftly removed the audio chip, now the short was gone, the phone was able to turn on without any issue, however, I noticed the baseband was gone, there is no firmware in settings . I guess the baseband was somehow disturbed in the previous failed repair. There is no option left but to remove and reball the baseband CPU. I successfully removed the baseband CPU and without pulling any pads. However, the phone won’t turn on. :(

My question is, will an iPhone 7 turn on without a baseband CPU? I know iPhone 6 series can turn on without a baseband, but I am not sure on iPhone 7.

You need baseband CPU to boot up the iPhone.

If too much heat was used for audio IC removable previously I would suspect baseband CPU needed to be reballed.

When you mean baseband CPU did you mean baseband PMIC?

Thank you Ben, I didn’t expect I can get an answer so quick. :) So Apple changed the design on iPhone 7. I remember on iPhone 6 series phones can turn on without a baseband CPU.

Ain't got much experience with iPhone 7 BB issues. iPhone 6 and 6S boot without BB without a problem, is this a new "feature" since iPhone 7 ?

Oh, I missed your last sentence. By baseband CPU I simply mean the baseband chip (BB_RF), not PMIC, or baseband PMU.

For my case I have an iPhone 7 with no baseband ic at all they removed it but it powers on an stuck showing unable to activate
