PoC WebOS - Palm Pre v1.4.1
A list of hash keycodes which run via the tel:// protocol and other info about vaild protocols on the Palm Pre:
Display Information
* ##DEBUG# (33284) (CMDA only)
This opens a "Debug Parameters" page that contains technical data on your current signal and tower connection. Signal strength is given as RSSI, which stands for Received Signal Strength Indicator. The closer to zero the RSSI value, the better the signal.
* ##GPS# (477) (CMDA only but there's a patch, available in Preware, for that)
This opens a "GPS Information" page that will give you location, altitude, speed, and accuracy information gathered via GPS.
* ##HELPHELP# (43574357)
This opens the "Device Information" page.
* ##RADIO# (72346)
This displays your telephony radio firmware version.
* ##RTN# (786) (CMDA only)
This opens a "Reverse Logistics Support" page that tells you how many minutes the unit has on it, how much data has transpired, the warranty date, ESN, phone number, software and hardware revisions, refurbished status, etc.
Collect Logs & Perform Tests
* ##8011183#
This application is used to collect logging information from Palm's software running on a webOS device into a single file that caan be emailed to Palm's developers to analyze the reason for an issue.
* ##LOGS# (5647)
This application is used to collect logging information from Palm's software running on a webOS device into a single file that caan be emailed to Palm's developers to analyze the reason for an issue.
* ##MONAD# (66623)
This opens a "Monad" page that has a button labeled "CelleBrite Export." The Monad application is used to prepare certain data for export to a Cellebrite device.
* ##TEST# (8378)
This opens a "Diagnostic Tests" page with options for manual tests and automatic tests.
Change Settings
* ##TEARMEDOWN# (8327633696)
This enables/disables the "Sticky Dialer" feature. The sticky dialer feature, when enabled, allows the phone app to run in the background. It is enabled by default. When it is disabled, the phone application closes when it is not the "focused" card. This means that if you open the phone app, then go to browse the net, the phone app closes.
* ##EVDO# (3836) (CMDA only)
This opens a "EVDO Mode" page that controls your phone's EVDO Settings. It gives you the options to force your pre into the following options: 1xRTT only, EVDO Rev 0 only, Hybrid Rev 0, EVDO only, or Hybrid Rev A (meaning pick the best available). Hybrid Rev A is likely to get you the best speed, but if you don't have good reception in your area, you may want to choose something else to conserve battery life.
* ##SID6581# (7436581)
This enables/disables "Number Masking." Number masking, when enabled, masks all incoming call numbers as to ensure total privacy for the user.
* ##TTY# (889)
This enables/disables TTY.
* ##VPON# (8766) (CMDA only)
This enables "Voice privacy."
* ##VPOFF# (87633) (CMDA only)
This disables "Voice privacy."
Use Caution (you may disable your phone)
* ##A671648# (671648)
Get your MSL Number... use caution when fudgung with your phone!
* ##AKEY# (2539) (CMDA only)
Allows you to re-enter the 26-digit AKey on CDMA devices. Note: An incorrect AKey will deactivate the phone and you will need to contact technical support for the AKey. MSL is required.
* ##DATA# (3282) (CMDA only)
This stores all of your Sprint Data login information, including default gateway, etc. I dont recommend changing these settings unless your data services are not working. MSL is required.
* ##DEMO# (3366)
This allows you to put your phone into "Demo" mode. WARNING: Enabling the Palm demo will erase all of your personal settings and enable an instructional demo.
* ##(MSL)# (Whatever your phone's MSL is) (CMDA only)
This allows you to see/change your number. Do NOT change this to a number without notifying Sprint, or your phone will no longer work.
* ##OMADM# (66236) (CMDA only)
Open Mobile Alliance Device Management provisioning. MSL is required.
* ##PREV# (7738) (CMDA only)
This opens a Mobile Protocol Revision menu. MSL is required.
* ##USBPASS# (8727277)
Opens 'USB pass through Control' which makes it easier to switch into diag mode. MSL is required.
#*#377#. Ever wondered if there was more to this than just showing the system error log? That’s the Verizon variant of the error log code, which is one of the many (and often times mysterious) hash codes that give you access to hidden features on your Palm device.
Please note: The function of some of these codes still remain a mystery to enthusiasts. A lot of them were discovered through trial and error (yes, we have a lot of time on our hands), and while the presence of some of these codes can be easily discovered this way, their purposes are often more difficult to understand. We have indicated some codes with which users should be particularly careful. Also, these codes have only been tested on Palm OS devices, so we cannot confirm nor deny their usability on Windows Mobile devices.
There are three parts to a hash code - the prefix, the code, and then the suffix.
1. The Prefix
The first thing that needs to be determined before using hash codes is the prefix, which is a sequence of #’s and/or *’s, that you need to use. They vary by radio technology, and sometimes by carrier.
CDMA
* Verizon: #*#
* Sprint: ##
* Other CDMA: #*#
GSM
* All Carriers: #*
2. The Code
This is the second part of a hash code. The code is what determines which hidden function is toggled. The majority of these codes spell out a word or abbreviation, so it may be easier to remember ERR instead of 377. Note that ERR is not to be typed out on the QWERTY keyboard, but rather, on the on-screen keypad.
Commonly Used
* 377
Spells "ERR." It displays the last error which caused a soft reset, what program was running, line number, etc.
* 786
Spells "RTN." This the Phone Information page. It tells you how many minutes the unit has on it, how much data has transpired, the warranty date, ESN, phone number, software and hardware revisions, refurbished status, etc. Note: Please be careful with the options in the pull-down menu.
* 66
Spells "ON." Turns on the radio.
* 633
Spells "OFF." Turns off the radio.
Others
* 33284
Spells "DEBUG." This is the CDMA phone info screen, which contains a bunch of technical data on your curent signal and tower connection. Signal strength is given as RSSI, which stands for Received Signal Strength Indicator. The closer to zero the RSSI value, the better the signal.
* 49878
Spells "HWTST." This launches the Troubleshooter and allows you to perform a hardware test.
* 3836
Spells "EVDO." Launches Network Settings to force RTT or EVDO. This is useful if you don’t have EVDO coverage and want to force 1xRTT to prolong battery life.
* 3282
Spells "DATA." Allows you to log into data services.
* 8766
Spells "VPON." Voice privacy enabled.
* 87633
Spells "VPOFF." Voice privacy disabled.
* 744
Spells "SIG." Signal strength for select models only.
* 744625
Spells "SIGNAL." Signal strength for select models only.
* 8463
Spells "TIME." Displays the current date and time.
* 56228466
Spells "LOCATION." Displays GPS location data (does not seem to work).
* 000000
This will allow you to manually program the phone on Verizon devices. Use this if you are planning to sell your phone and don’t want the buyer to see your number. For non-Verizon devices, you need to substitute 000000 with your MSL code (provided by carrier).
Please exercise caution when using the following codes:
* 72346
Spells "RADIO." Shows radio software version.
* 8778
Spells "UPST." Toggles software download (bootloader). Note: You may need to soft reset your phone after this command.

Do note that you may need to re-program your device and/or contact technical support for a new AKey after running this command.
3. The Suffix
There are two methods to initiate the hash code. The first method works on all devices. After you enter in the code, tap the Dial button on the screen. The second method works on most CDMA devices and is the method I prefer. It is a single # after the code, which is a bit more convenient because you won’t need to reach for the screen.
