Htc Function Test Program

---

Found this on Modaco

I found this a while back, then wanted to use it today and had forgotten the codes
(I'm putting it here so I can find it again)

WARNING : Screwing around in these menus may brick your phone.

NOTE : This applies to GSM Hero phones only. I believe CDMA replaces *#*# with ## and #*#* with #

Hint - maybe someone might like to try this with the various radio versions to compare strengths?

HTC Phone Information Screens

Dialling *#*#4636#*#* provides the following :

Phone Information
- IMEI
- Phone number (if known)
- Current network
- Ping test
- Signal strength
- Location (signal latency & Cell ID)
- Neighbouring Cell IDs
- Roaming state
- GSM service status
- GPRS service status
- Current network type
- Message waiting status
- Call redirect status
- Call status
- Radio reset count
- Data attempt count ?
- Data success count ?
- GSM disconnect info log
- PPP sent count
- PPP receive count
- Number of PPP reset since boot count
- Preferred network type (selectable)
- Toggle ciphering (selectable)
- Toggle QXDM SD Log ? (selectable)
- Toggle radio on/off (selectable)
- Set/retrieve SMSC number (click Refresh to show current)
- Toggle DNS check

Pressing MENU will allow you to :

- Set your radio band manually
- View SIM address book
- View SIM fixed dialling numbers
- View SIM service dialling numbers
- Get PDP list (GPRS contexts IIRC)
- Disable data connection
- Disable data on boot

Battery Information (what you get in Spare Parts anyway)


Dialling *#*#3424#*#* provides the following :

HTC Function Test
- Test LED, Backlight, Vibrator, Display, Audio, SD card, Camera, Button, HST, Touch, System, Battery

Don't blame me if "SD Test" (or anything else in those menus) wipes your card/phone/dog......

EDIT (10/01/2010)

Using information from http://forum.xda-developers.com/showthread.php?t=540483 I've dumped all my .apk files and searched for the codes...I found nothing *new*, but the GTalk Service Monitor is valid...

*#*#8255#*#* -> Google Talk Service Monitor (Talk.apk)

This is rather more interesting, as it shows :

- Google Talk host address & port
- Your Google JID (presumably Jabber ID, as GTalk is based on Jabber IIRC)
- Your Device ID (this is interesting, and presumably hashed from something - will check across ROMs as I presume this MUST stay the same)
- GTalk connection status
- GTalk heartbeat status (presumably when it checks in to GTalk?)

how does this work if i dial that number i just get tmobile telling me calls to this number are bard ?

You've got an EVO working on Tmobile?!? You're not supposed to actually hit send or talk or whatever, just dial the numbers and the menu should pop up in a few seconds if it is enabled on your phone. Works on the EVO and also did on my Sprint Hero.

This doesn't work on the Evo, or at least mine.

##3424# is ##DIAG# There are no options, but it does put your phone into diagnostics mode. This is useful if you install the diag drivers on your computer and use cdma workshop or something similar.

*#*#8255#*#* and ##8255# do nothing.

Some other codes below if you are interested:
