Hi all!

I'm newbie on PDA's area :). I have just up my LG KS20 to WM 6.5 build 21193.5.0.0 PV. Now, I want to use other version. But when I using 2676625720# then it show Engineering Menu. I can not setting USB Switching to "LG Composite -DUN, DIAG" because that menu can not access. Anybody can you help me?

Hi
there is an other way to flush LGKS20 called "emergency" :


(b) Emergency mode connection method
Step 1: Unplug USB from your KS20 and switch it off

Step 2: Press and hold "Send" and "e" key, then press "Power" key while you are still holding that two keys. A Green led should come up and stay on

Step 3: Plugin USB and connect to LGMDP(LGMDP_EURO)

hope it will workarround our problem. i 'll test it tomorrow inchallah

After upgrading to KS20 WM6.5 CE OS 5.2.23034 (Build 23034 FB) WWE Clean, the engeniering menu is operational again.
