iPhone 7 7p Intel BaseBand D15 stuck low fault❗️

These Models prone to have BB D15 pin Defect inside BB IC Causing No Modem Firmware & BBpmu in shut Down Mode


D15 gets stuck Low inside BB Modem IC, causing modem to remain in sleep mode forever.

To Fix this issue We have to isolate D15 pin under Baseband IC
Using UV curing solder mask will isolate the connection and thus prevent the baseband going into sleep mode.

It is not known if there are any long term issues with not letting the base band enter sleep (such as battery drain) but it’s better than having a useless phone.
