iPhone 7 Prior Audio IC NO IMEI

Hey there, received a prior Audio IC repair which doesnt have an IMEI, reballed baseband but still no IMEI went to flash and its stuck at writing filesystem :(

Help would be lovely!

Update

It restored but still there is NO IMEI. Usually its just a bb cpu reball and IMEI shows back up but this time no luck. :(

Anyone can help? Its an intel board and I found a short on C5814_RF (VPMIC) line, while trying to remove C5814_RF, the pad ripped off too, then realized its a bad BB_PMIC. Is C5814_RF an imp. component or can I make baseband work without it present on the board?
