ANSWERED Samsung Note 10+ (SM-N976B) bypass OVP

[fhulgzz]

Hello,
Nag bypass ako ng OVP, after jumper na detect na charger, may display na charging sa screen pero 0 amp consumption nya, hindi rin tumataas battery %. So meaning fake charging lang xa. See pic 1.

I think merong switch ung OVP IC, base sa schematics kasi meron dalawang enable signal pero diko alam saan iconnect ito. Walang details sa schematics. See pic 2.

Baka meron kayo idea jan, pa share.

EDIT: Fix na po, pinalitan ko ulit ng charging IC 2 times. Ung unang palit same problem kahit brand new IC, pinalitan ko ulit bagong IC so ayon ok na. Maybe factory defect ung isang IC or sa balls, kasi 2nd IC kahit brand new ne reball ko ng 183.
