HI,,

try to measure 32.768Khz first , and measure VBB from UEM !
then make sure that system clock is working , like 26Mhz, like 13Mhz!

there is easy to check VBB !
when phone install bettery, then try to power on it,
then you measure that VBB, is it HIGH or LOW !
connect your MBUS to a led, to measure it


Willy

Try to resolder BGA components use hot air station then reflash your unit. I revive a lot of 8310 with this metod.
Best regards,
