Treo Hash Codes

[KLockemy]

I found this and wanted to share.....

Most of these work, some doesn't. Just be careful cause I am not responsible for what you do with it!

#*#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.
• 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 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.
• 000000
  This will allow you to re-program the phone number for Verizon devices. Use this if you are planning to sell your phone and don’t want the buyer to see your number.

Please exercise caution when using the following codes:

• 8778
  Toggles software download (bootloader). Note: You may need to softreset your phone after this command.
• 3424
  Toggles passthrough.
• 7277633
  Turns off passthrough.
• 83843733
  Toggles tethered mode.
• 88722366
  Trace enabled. Note: You may need to softreset your phone after this command.
• 887223633
  Trace disabled.
• 28722366
  Trace enabled. Note: You may need to soft reset your phone after this command.
• 287223633
  Trace disabled.
• 798722366
  Trace enabled. Note: You may need to soft reset your phone after this command.
• 7987223633
  Trace disabled
• 774
  PRI checksum, and allows you to reset the phone to factory settings. Note: This command can delete all data from your Treo. If you do not have recent backup, do not test this code!

3. The Suffix
The simplest part of the hash code - it’s a single # after the code.
