Diagnostic Menu on the HTC 8x

[theWindowsCow]

My previous phone was a Dell Venue Pro. There is a easter in HTC and Dell WP7 that allowed into a hidden menu/app. Dell Venue Pro has a secret easteregg - Windows Phone Hacker

I tried the same code on the HTC 8x and it worked.

1. Dial ##634#
2. Accept

You can test LED, vibrates, and flash. It also installs an App called CSDDiag

Ha, nice. Just tried and it works. Pretty pointless but interesting though. Nice one!

 

[pepsijosh]

I just did it to =D
Doesn't really let you test allot though =/

Yep, I saw this a while ago over at xda. ##3424# also brings up the same app - useless but there you go

This one brought up the tests for the flash, LEDs and vibrate. The one in the first post brought up radio tests and something else I didn't want to mess with as I didn't understand it. It lets you test 1x, EVDO and GPS radios, giving you detailed info on signal strength, channel etc.

Really you got different test with ##634#? Mine are the exact same.

 

[jaethos]

Yeah, on my Verizon 8X it brings up a screen labeled EmbeddedTool. It has two selections available, one is Diag, with a couple settings I don't really understand, and FieldTrial, which gives me the radio options. I now have an app called DiagnosticTool that, when selected, gives me a screen with my MEID, IMEI, SIM ID and VERSION. I can't do anything though, it's just the info.

Yeah, on mine (o2 uk) ##634# aka ##MFG# and ##3424# aka ##DIAG# are the same menu. Different 8X's seem to have different settings though!

I see I am T-mobile US

 

[markk132]

any changes we can make on the Verizon 8x's that will enable group messaging?? lol

This is not working for my HTC 8X on AT&T. If I enter ##634# or ##3424# the numbers disappear when I enter the last # and nothing happens.

Tell me, was your Venue Pro able to be jailbroken? When I type in ##634#, it takes me to a screen where it says I could transfer some sort of data between the device and a PC.

Does it allow you to set your phone to 3G only mode? My phone is always on EDGE even I have strong 3G signal here and I am dying for the 3G only lock setting!

For the LED test, there's green, red, and key. Anybody knows what the key does!

Key is the softkey backlight.

I tried it on my Verizon 8X and got the same.

##778# brings up the Verizon PST servicexmwnu which allows you to change a host of settings. Its the one the service techs use. I'd advise not fooling with it unless you know what you are doing.

I got the same embedded tools. wondering if the Diagnostic Mode could be used to jailbreak/root the device like android.

CSDIAg could be starting by using these codes
##634#;
##778#;
##786#;
##3424#

with the last update it has much better tools to test your phone.
