Modem from combination is not working. We need ENG modem binary 4.
@Eerchant - what kind of modem are you sharing pls?
@mobileplus21 - pls post logs. Thanks.

No solution yet for unlock bit4 firmware.Only msl code can help you.
We are waiting for unlock A520F bit4....

maremestera · 05-10-2018, 19:53

Until someone shows a log, I say MSL will give same error as read code/ save cert diag on bit4.
