Infinix Hot 11 Play (X688B) – VS1 Line Short After Replacing Power IC (MT6357CRV)

Hello everyone,


I'm facing a problem with Infinix Hot 11 Play . The issue is related to the VS1 line short on the Power IC side .





I replaced the three Power IC .After installing the new IC, GR becomes normal. .
But once I insert the battery , the VS1 line gets shorted again .

It seems the short is coming back every time after battery insertion.



Please suggest what else I should check — maybe any capacitor or VSYS-related line that could cause the short.


Thanks in advance!

Judging by the name, VS1 is supposed to be a switching voltage regulator, so I suggest replacing it's coil. Also, the MT6357 chips from AliExpress was known to be completely counterfeit and non-functional, so try installing this chip from a good, working donor.
