iPhone 11 Cellular issue Detected

Requirements para ang procedure na ituturo ko ay sakto ang solusyon
Modem Firmware - Blank
Baseband Version Blank
*#06# blalnk din
walang lag ang unit

QnA sa client:
Sabi ng customer minsan nag karoon at bigla na lang din nawala ang signal << --- ito mahalaga
nabagsak? hinde naman masyado



sipatin ang board kung pantay
Ang dapat gawin ay "IDIKIT ng MAAGI" yan lang ang gagawin dahil sure na hinde connected to each other

pullup ang board (obvious na may nag separate na itong unit na hawak ko)
ilabas ang tools yung may pang press sa ibabaw (see attached picture)
lagyan ng flux na liquid kagaya ng nasa picture
salang ng 4 minutes na may 180c na temp

then update or retain flash s 3utools (huwag full restore ha)

Done
