| Hi
I use these guidelines for phoenix program, flash fails:
TXD Line High - change UEM
TXD Line Low - change UPP
Ms ID Failure - change flash prom
MAD NAK Aknowledgement failure - change UPP
Beings you've changed the UEM already using the BGA rework machine, and to your visible eye, the UEM change was all ok.
Best bet is to go for the UPP.... |
