HTC Apache Cradle Disassembly

Can anyone tell me what type and size etc the four screws on the bottom of the Apache charging cradle are? One of the six sprung pins on the cradle has stuck down and, as a result, the spare battery charging feature has stopped working. I'm guessing I need to disassemble the cradle to free it. Any non-invasive ideas also would be welcome.

The screws are micro-TORX. You can find a driver at Sears. Red handle with multiple bits.
You might want to just try daubing a little bit of contact cleaner or alcohol Kor even WD40) onto the stuck springy-pin. That and a little jiggling might free it up enough to work.
I recently rescued a malfunctioning after-market wireless Xbox controller with a few drops of WD40 worked into the joystick micro-pots.
Its a T-6 I modded one so I could use it with both my 6700 and my hermes

I think your new battery is bad quality, or may not be original to
HTC Herald, Wing, P4350
you should try to look at http://shop.ebay.com/?_from=R40&_trksid=p5197.m570.l1313&_nkw=battery for Htc Wing&_sacat = See-All-Categories
I know the price is $ 6.90 (free shipping)
try to clean the terminals of your charger or the usb port of your phone with a dry tooth brush and an acetone, you must remove the battery before doing this ok.... and wait for the acetone to dry and plug your new battery in,
if that didnt work, try to shock your new battery using an adapter, put it on 12v dc and put the positive wire on the positive terminal of your battery and ofcourse the negative on the negative pole....
the new battery has no charge left. it is in total drain.... you need to kick in a small amount of charge in it by doing the shock....
Same problem !
My new battery does not charge on Herald.
BUT... my Herald battery, and the new one, DO CHARGE fine and well when inserted in my Kaiser.
Also, Kaiser batteries don't charge in the Herald.
So, I thought my Herald has something which recognizes its only and official battery and does not accept any one. Or my Kaiser does not have this and accepts any battery.
Any trick / suggestion ?
THANKS !!

Using the Battery power points? (USB has broken)

Any ideas on the pinout for the 3 pads on tha back of the phone, my micro usb has busted, and I need it powered up.
Cheers in advance
+1
My usb isn't completely broken, I can still transfer files if I hold the cable end in a funky position, but it's useless for charging. But I feel like I could whip up a charge-only port on the back if I knew which contact did what.
Maybe some info from car cradle or powermat users?
Those are the only 2 devices which use the 3 contacts right by the battery, as far as I know
Hmm, I cant fathom it, surely sumone knows what the three contacts are?
bump....
anybody?

I did, months ago.
But if I knew for sure what voltage/polarity to put to which contacts, I wouldn't have to pull my battery out to swap it with the one in the charger every day. I don't like being at risk of bending my battery pins all the time, or worse yet, stressing them and having one break off.
The external charger works great and all, but I need a charge cable. And the powermat is out of the question for me, how does my phone lay on the mat and charge when it is usually in my hand? I'm not gonna waste my money on something so impractical, especially since I'll have a charger and port set up an hour after I see which contact needs what volt/pol.
Could somebody with the car dock please put a DVOM (digital volt/ohm meter) to the battery contacts of the dock and see what contact is +/- and what voltage?
Thanks for any help anyone here can give.
Bump... cant find a pinout for the 3 contacts anywhere. Can somebody help by testing the voltage/polarity on the powermat battery/cover contacts?
-HD2 Android-
Ive been trying to figure this out forever. The orginal dock it the only thing that used them. No other dock or powermat does. Unfortunately the dock never made it to the consumer and there were only a few out to some sites early. Working on getting he right person at HTC or finding someone who has the phone apart and can trace them out.

[Q] battery bay charging terminal pinout?

Hi guys, does anyone know the order of the pins under the battery cover for charging? my usb port is very close to death but I don't want to pay to get it fixed when i've got my upgrade in less than a month so I figure i'll just adapt a charger to charge via these.
Same here, bad usb port. I have looked everywhere trying to find out what voltage/polarity to apply to each of the 3 contacts under the battery cover, and even tried applying all possible combinations of polarities to the 3 contacts with a low voltage, all to no avail. My best advice to you, which has worked very well for me, is to buy an external battery charger and an extra battery. I got the battery and charger for 16 usd for both from ebay and they work fine. Good luck to you
someone must know the pinout, I mean the phone is so old someone must have played with it successfully.
Well, you can't just put power to the battery directly, it probebly will explode (Li-ion).
You can buy an external charger (look on ebay or phone shops) or fix the power part of the usb port:

[Q] broken micro usb port (direct charging)

hi,
well i managed to snap my charging port inside my hd2 and well, i get nothing when my charger/usb plugged in... im wondering about directly charging the battery whilst being able to use the phone at the same time... ie having the charger contacts on the phone and battery at the same time... wondering if this is possible as i dont want to damage the battery/device...
also what would i need to hook to each contact? i know positive n negative poles but is what the middle contact??
any help with this would b much aprieciated... thanks
luke
p.s i couldnt see anything that would help me in the other forums i looked at
Yuor best bet is to buy a 2nd battery and a battery charger from ebay then use 1 battery whilst the other charges.
Its not to expensive to repair, if thats the only fault
i see ur from england too so do u know any cheap places that can repair this fault? links if possible... thanks
any joy? I found the following two websites but am now weighing up my options.
htcphonerepairs.co.uk/HTC-HD-2/Charger-Port-HD2.html
simtekworld.co.uk/index.php?route=product/product&product_id=529
I have a similar problem. Don't know how or why but for some reason it suddenly stopped charging on Friday night. £50 to get it fixed is a bit excessive.
I wonder if a battery charger might be a better option?
EDIT: the answer to my own question (so far, at least) is "YES". Bought a cheap charger and battery off ebay and both are working well (touch wood). It's a pain in the butt having to change battery and not being able to charge it in my car but it's also quite useful having 2 batteries.
