procedure.

Mobile phone software update

Do not carry out a software update before repairing a unit!

If a software update is executed before a technician examines a defective phone,
it is virtually impossible to find out whether a phone with an NDF diagnosis (No
Defect Found) is correctly labelled NDF, or whether the original defect was
eliminated with the software update.
