A fix for the failure to wake/SOD, well for some!

[flacoman91]

sorry to thread resurrect, but I found this after searching and wanted to share my solution/issue with anyone else trying to figure it out. This is even more important now that sprint will charge you more if you do an esn swap.

I figured out that I could get my phone out of sleep (turn screen on) when I had the keyboard open and the screen tilted back (away from you) and I hit the power button on.

It's definitely a short in the light sensor somewhere. You can prove this if you install Lumos. When you configure Lumos, if you see a light reading of zero and then open the keyboard, you can make the sensor work and broken again if you flex the keyboard/screen chassis.

the best solution to the SOD issue was to just not use the stock sprint 6.5 ROM. i cant believe people actually got replacements over this

It's a hardware issue with my phone. I've done the flash dance many times, flashed to stock, flashed to old roms, new roms. I've always used a custom rom. In my case, I use Energyrom titanium version.

Technically the phone never went to Sleep, it's just the darned screen won't come on because of the defective light sensor once it's off. You know it's on because the keyboard, phone send and hang up buttons are lit up when you slide it open after attempting to wake the screen by hitting the power button.

I thought other people were crazy too, until it happened to my phone. My bro has the same phone, but he doesn't text as much as I do, and when he does, he uses the touch screen. My guess is heavy sliding open and closing weakens a circuit somewhere.

April 23: Edited for some of your stubborn phones.

Warning: ***I can't guarantee this will work for your phone so results may vary but it has worked for 3 phones I fixed***

I've waited a month to be sure that this works because every time I'd uninstall a cab and my phone worked fine for an hour or a day I thought I found a fix...but then reality kicked it the very next day. So rather then starting another complaining thread I decided to post a solution.

Here s what worked for me....

1. Optional yet recommended. If you are using an aftermarket wall charger.....go back to the OEM usb cable that came with your phone...yes its a little flimsy...(at least mine was) If your car manual recommends 5w30...you put in 15w20 in your car and something goes wrong down the road....who should you blame the manufacturer? your girlfriend? momma?

2. Flash back to STOCK and CLEAR STORAGE 2-3 TIMES. (You should notice your backlight working perfect again) Then flash to the rom of your choice and then CLEAR STORAGE 1-3 between each time check to see if its working properly... Once you find it working well....Move on to the next step p.s. learn to use sashimi or a similar program makes life soo much easier.

An alternative to overdosing on that, "clear memory" button that you can use is Task 29 as mentioned by mjh8812 to fully destroy and annihilate all (backlight/screen system files) flash your rom of choice.

3. Install lumos v10 rc2 (yes it will work fine on the tp2) when your doing the calibration use natural sunlight preferably not on a bright day) so that in low light levels your phone will have no trouble sensing light. On certain programs like coreplayer or your ebook reader you can even have special settings to have a brighter screen no matter what lighting conditions your under. The proximity sensor on our phones is also on my list of suspects....especially when I'd look in the registry and it would say that it was disabled, "0" but yet when I'm on a phone call it works?! * **After you've done the calibration, saved and soft reset your backlight should be working just fine***

4. If you are using a locking program, such as s2u2 upgrade to the newest version...I use s2u2 2.40. Regardless of the app your using keep it up to date. If you going stock, you just saved yourself a step
After doing all these things I haven't had a failure to wake/SOD in one month no matter how hard I try to get one.

5. Lastly now that you got it working.....DON'T drop your phone... ever!

However, if you do and your phone still works but the problem starts again, repeat steps 1 - 5 and cross your fingers.


After I jumped through all these hoops I haven't had a single problem with my backlight in 1 month. Believe me when I tell you I hated this phone, but thats changed So after jumping through all these hoops I hope that you fall back in love with your tp2 like I have this past month.

Peace

Havent we already came to a conclusion that it was a certain build causing the SOD ? and that those who have flashed to a newer build , 21916 , i beleive , have eliminated SOD ? im on 21916 and never had a single SOD yet , in like the 1+ months of running the same ROM .

But great find and hope it works for everyone ! And as far as loving your TP2 . you should have loved it from the day you bought it , if not , you arent a true ppcgeeks fan xP lol jp

I love my TP2 , only complaint is the snail like processor . they should have put a 1Ghz processor in it . especially for the price we have to pay !

Is there someone who might be able to send me a link to the newest version of windows 6.5 for my HTC touch pro 2? Is there a version 21916 of 6.5 professional? I have had cooked roms on my phone, but find it a lot easier to keep the stock rom, so if someone had a link to a stock rom that would solve this backlight issue I sure would appreciate ie!!
