iPhone 7 VDD_MAIN Short after Audio IC repair

Hey there people,

Facing a weird problem, Had a customer bring in an iPhone 7 for classic Audio IC and i did the necessary steps but it had the same issue, removed audio ic again and installed a new one but now the phone has a VDD_Main short and i’ve tried looking everywhere, even use Rosin Smoke method to see what is shorting VDD_Main but no luck, Ive also checked every cap for bridging but nothing. Im stuck here, happened to me the first time tooo, Done dozens of Audio IC’s but never faced this….

Any help would be appreciated! :D
