If You face an issue like Reboot on first logo

Then fault may from Battery sensing and thermal lines ।
But when Dc to Dc ic and Power ic will be of same configuration for e.g Pm660 and Pm660L if you found issue like rebooting on logo, you must have a look on vph or vsys supply and if you found its missing with proper gr on line then go on check Pm660L Ultra LDO section may LDO 3.0v or and 2.8v will be short due to faulty cap.
If you found this usefuy please reply। Peace
