Phone cannot be powered on (II)

Context
If this kind of failure is presenting itself immediately after FLALI, it is most likely caused by ASIC's missing
contact with PWB.
If the MCU doesn't service the watchdog register within the UEMCLite, the operations watchdog will run out
after approximately 32 seconds. Unfortunately, the service routine can not be measured.
