Wow... It's been quite a while since my last post on this blog. Confession time has come. I was doing my ordinary stuff as in working, traveling, having the time of my life...
Just a few days ago I came across the post on Eten Users forum that touches the deepst desires and the most intimate passion of all E-Ten G500 owners. It brings WM6.1 to G500! The idea was so crazy that I decided to give it a shot. Guess what - the update worked but then a nasty showstopper took place..
My update progressed up till the first WM6.1 setup page - Screen Alignment. The cross popped up asking me to tap on it 6 times in different places on the screen. Well, what can be simpler someone might think... Guess what, I failed more than 15 times. Then it hit me - there's a software workaround. With absolutely non-working hardward or even totally absent screen one can easily step over this problem and fix it in future. Here's how...
You need WM Registry Editor. You may use one bundled with Visual Studio 2005 / 2008, Mobile Registyr Editor or any other just make sure that it's running on your desktop. Hook up your PDA to your computer and let Active Sync connect to the device. Now you start your registry editor and connect to the newly patched WM6.1 gadget. Navigate to HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH key and modify the MaxCalError (calibration error barrier value) from 7 (default) to say 2000. Tap the last 5 times on the screen and enjoy your new interface.
Now it's time to adjust your calibrated data to make sure you can use your device properly. Here's a similar post on XDA developers forum. All you need to do now is to modify your CalibrationData value in the same registry key with "495,634 132,248 126,1010 858,1010 858,240" which stand for an average calibration data collected in 5 attempts.
CAUTION: If your device has a different calibration values than the posted above then it would stop loading at all. Think twice before updating CalibrationData and do it at your own risk.
If you did screw up your WM6.1 instance and device doesn't boot anymore - don't panic. You'll be just fine. Do a physical hard reset:
- Press Power Button and Reset Button together and release them at the same time.
- Immediately before device starts to reboot, press and hold End Call Button for approximately 15 seconds until the "Erase all data and loads defaults ?" screen appears. Click Yes.
Now you can give it another shot to patch your G500. Hope this helps anyone just as it worked for me.
