Hello Sir,
Thanx for ur reply.
I replaced the UEM using BGA Rework machine.
Before change IC i tried flashing using Pheonix.
It shown NAK Aknowledge fail.
As per the service manual i found it is because of UEM.
I replaced UEM, now it shows 'TXD Line high".
So can u please help me to know how to check continuuity for UEM by Multimeter.
Best Regards
