Hello/Moin,
I have an Wazard with a bad akku. I only use the Wizard for testing. The problem is, that I have made an firmware update with the bad akku. In the middle of the updating-prozess the akku was empty. Now I have an wizard, with ist starting the three color screen in an endless modus.
I have a laboratory power pack. I can set the voltage an the current. The WIZARD has six pins for akku. Which voltage has to be attached to which pin?

The same Text on german: Hallo, ich habe meinen Wizard zerschossen. Beim wechseln der Firmware hat der Akku aufgegeben. Jtzt startet er immer wider diesen drei Farben screen. Wie kann ich den Wizard direkt an einem Netzteil betreiben? Welche Spannung muss an welchen Pins anliegen?

hi,
the voltage you'll need is 3.7 volts. And if you face the pda from the back, the upper pin is the positive and the last pin is the negative, so you don't need the pins between the first and the last.
I've also found a dead battery fix on the net. I'm with the same battery issue, but the fix won't help. Maybe it works for you?
There are two options, the first one can be found here: http://asktheadmin.wordpress.com/2007/06/20/htc-wizardcingular-8125-dead-battery-fix-errr-jumpstart-pt-1/
And the second option if you cant find a second battery: http://asktheadmin.wordpress.com/2007/06/22/htc-wizardcingular-8125-dead-battery-fix-errr-jumpstart-pt-2/
Oh, and if you know other ways to fix my pda, could you tell me how?
Good luck!

Once my computer just up and turned off in the middle of a flash. After this it would only go into bootloader mode (RGB screen.) Good thing I ripped my original ROM with WST (Wizard Service Tool), as my piddly lil carrier doesn't have a official rom that I've found.
In my experience, if you can get bootloader and it says "USB" in the bottom left when connected, you can flash your original rom (or part of) to your phone with the no id version of RUU.
Although I haven't experienced the dead battery issue, I don't think the RGB would load in that case. However, pinouts.ru is the shiznit. Happy hunting.

Im kinda unsure what your problem is
Is it you cant access the boot loader to flash a new rom??
Or is it you dont have a battery??
Did ya try booting while holding the camera button with the stylus pressing the reset button?
also you can get a new battery for $10 at

@ SlimDan22: None of your 2 options.. His problem is that he flashed his rom and in the middle of the flashing process, his PDA turned off. Because he has a dead/bad bettery. So the only thing he has to do is charge his battery with the wallcharger to 100% (from 0% to 100% it takes 4 hours according to the ser vice manual). Then connect it to the pc and get the bootloader in USB mode. You can do that by holding the camera button and press the reset button with the stylus. Hold the camera button until the device restarts, then follow the on-screen steps (just press the send key, the green button)
Then the device is in USB mode and you can flash your PDA again;)
I've got nearly the same problem (exept the reboot in the middle of the flash process) so i've got to fix my battery issue.
This is what I'm doing now:
I'm testing my PDA with the htc battery diagnostic tool "PowerDetect". I've attached the tool if you want to use it;)
I also found the service manual at: ftp://xda:xda@ftp.xda-developers.com/Wizard/Docs_Tutorials/Wizard_Service_Manual.pdf.
I've put back the original Rom temporary now (WM5, not WM6) maybe that was the problem but my battery issue started before I upgraded my PDA to the newest TNT software.
My prevous software was TNT 5.0, that's where the problem started (after a use of a couple of months..)
I hope I can fix my phone, because I've no warrenty anymore. It's second hand and i teard off the warrenty label..
We'll see if it works..
I've heard about many issues with the wizard but this is the most annoying one until now:P
Succes fixing your phone;)

My problem is nearly solved:)
After some tests with multimeter and PowerDetect I found out that it was a bad battery problem. There were many options:
1. bad battery
2. corrupted chip on mainboard
3. bad contacts (oxidation on pins)
4. software bug
So it was #1, I don't need help anymore..
The website for a new battery wich SlimDan22 linked, was very cheap but only ships in UK and I'm living in the netherlands but I found a good website if you're living here: http://shop.strato.com/epages/61396109.sf/secoKSHUJAaOLc/?ObjectPath=/Shops/61396109/Products/PDA16010
It has many models of batteries but only ships in the netherlands so..

PS. @snowyrain: would you tell me if it worked for you by just connect a powerpack to the pins? maybe i'll do that instead of buying a new battery..
