Fixing my HTC 8125

image I’m going to post a few things here that the vast majority, if not entirety, of the readers of this blog will not care about.  Nevertheless, one the reasons I post to this thing is to document my adventures in technology.  As I often say to people when giving them computer advice or programming, I know enough to know what should be able to be done "under the hood" of your CPU but in most cases I don’t know exactly how to do it.  That’s where my buddy, my pal, Google steps in.  After all, I am a confirmed "Google Master" with mad orienteering skills.

Problem:  WiFi on my HTC (Cingular) 8125 phone stopped working.  When you enter the Comm Manager and attempted to activate the wireless, the "I’m thinking" icon would spin away for about 15 seconds and then the Wifi would remain disabled. 

Attempts at solving the problem:

  1. A number of soft resets were attempted, to no avail.
  2. Not recalling how to perform a hard reset, I attempted to remove the battery and plug it back in.  This is when I discovered a new problem: The battery panel would not come off.  Tugging, pulling, prying. It wouldn’t budge.  I managed at one point to get my thumbnail under the plastic edge, slicing through the skin connecting my nail to my thumb.  Finally, loosening the edge and peeling it back, it was free.  Some of the label of the batter had turned up and adhered to the back of the battery panel.  All that for nothing, because removing the battery did nothing.
  3. Under Settings, Clear Storage is an option to do a full reset of the phone, which I did.  This still did not help.

What to do, what to do?  Off to Google:

  1. I found one forum entry describing exactly my situation (http://www.htcwizardweb.net/node/2213) but there was not solution and in fact, the author decided he was ready to buy a new phone after several respondents were unable to help:

  2. I had for a few months, my wifi up and running, and was able to connect to my home airport. one day, wifi disappeared. i go to comm manager and choose wifi, get the spinning circle, but it won’t turn on.

    ROM version 2.25.11.1 WWE
    ROM date 5/11/06
    Radio version 02.25.11
    Protocol version 4.1.13.12
    ExtROM version 2.25.11.102
    Windows Mobile 5, 5.1.195, build 14928.2.2.0

    Even going to Wifi Settings from comm manager doesn’t let me do a thing, and setting up my connections, can’t see wifi.

    I’ve done several soft resets, and with no luck, did a hard reset. I can activesynch to my exchange via GPRS fine.

    Also, have a 1 GB mini SD card, and phone won’t recognize its there. are the two related? is my phone end of life?

  3. I recalled using a registry editor to modify settings to disable GPRS permanently, since I had no use for it and it wouldn’t turn off with just software.  I figured there might be a setting I could use to bring the wifi back to life.  Alas, I got lucky and, this time, with no help from the web, I managed to get the wifi back up and working.

FINAL SOLUTION:
DISCLAIMER: I take no responsibility for any "mess" created if someone uses the following steps to fix a similar problem. Anyway, this worked for me.

  • Download and run Mobile Registry Editor (make sure your phone is connected)
  • Navigate to HKEY_LOCAL_MACHINE/Comm/TNETWLN1/Parms/
  • Change the DWord values for the following items all to 1:
    • HTCResumeWifiAfterReset
    • HTCPreloadWifi
    • HTCPreloadStatus
      (I’ll be honest, I don’t know which one fixed my problem but I’m not about to undo them now, in fear of breaking it again)
  • Ouila! 

NOTE: I also went back and disable GPRS as before.  Navigate to HKEY_LOCAL_MACHINE/Comm/ConnMgr/Providers/{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}/Connections.  On both Cingular GPRS and My ISP GPRS, change Enabled to 0.

All I can say is WOOHOO!! (and my thumb still hurts)

Murphy’s Laws for Mathematics

I was finally catching up on some blog reading today (Yes, I should be finishing the grading of my Differential Equations tests, but I was kind of cranky this morning for no apparent reason. I’m sure my students would prefer me to be in a good mood before I start grading)

While reading the Carnival of Mathematics over at Walking Randomly, I was pointed in the direction of "Murphy’s Laws for Mathematics".  I’m sure just about everyone knows the fundamental principle called Murphy’s Law:

  • Murphy’s Law: If anything can go wrong, it will.
  • Corollary 1: At the worst possible time
  • Corollary 2: Causing the most damage
  • Over at the site, Murphy’s Laws and Mathematics, we see how that works itself out in a mathematics course.  Here are a few of my favorites:

    • Every problem is harder than it looks and takes longer than you expected.
    • Notes you understood perfectly in class transform themselves into hieroglyphics at home.
    • The answers you need aren’t in the back of the book.
    • No matter how much you study for exams, it will never be enough.
    • The problems you can work are never put on the exam.
    • The problems you are certain won’t be on the test will be.
    • The answer to the problem you couldn’t work on the exam will become obvious after you hand in your paper.

    This page was linked to over at 360 and I found his additions worth quoting as well:

    • That brilliant insight to the problem you’ve been working on for weeks will disappear the moment you find some paper to write it down.
    • The set of GREAT exam questions from a teacher perspective and the set of GREAT exam questions from a student perspective are nearly disjoint.
    • If you wait until the last minute to print/photocopy something, the printer/copier will most surely break down.

    Now that I am using Office Live to store my PowerPoint slides for my Intermediate Algebra course and also teaching an online Algebra course as well, I have a  technological addition:

    • Any online tool essential for your curriculum will be unavailable from 30 minutes before class or an online exam, until roughly 2 seconds after other arrangements have been made.
