You say you checked "the various" PMIC outputs. Did you check them all or only a few of them. That does make a difference from a troubleshooting perspective.
 
If you have and they all checked out okay, then I would check the outputs from U_BB_RFU_PMU_RF as well. Problems with the BB PMU can also cause bootup issues. If everything looks okay, I focus on the charging circuit and make sure it functions properly and then replace Tristar to see if that helps. Report back!
