important information about "hanging" or "rebooting" K790 phones.

K790 Phone hang

Only Applicable for K790!

Background:
One of the main reasons for permanent phone hangs at start up or standby
can be resolved by replacing two resistors under the Bluetooth cavity.

Instruction:
ROA (PCB) with revision R3A and R3B have not been modified.
ROA (PCB) with revision R3C has the new resistor values already from
factory.
ROA (PCB) with revision R3D has a new version of Dolphin 2 which prevents
the problem and they SHOULD NOT have the resistors replaced.

For ROA revision R3A and R3B with permanent phone hang at start up or
standby:
Change:
R1404 to 470 ohms, REP 621 003/47.
R1405 to 4.7k ohms, REP 621 004/47
Both resistors are located under the Bluetooth cavity
