There have been quite a few postings here on people having problems charging their XDA with thrird-party chargers originally built for the XDA I.
Add me to the list I"m on the road and can't get the damned thing charged using the charger.
However the good news is, that the problem is not the cable (or the connector for that matter). Right now I'm in the internet cafe using the USB-connection to charge the XDA II at least a little. THis is working!!
My third-partz charger is a power supply with a USB-socket, that connects with this charge-sync cable. But, its not working! This leaves two possibilities:
1) The power supply is providing a lower voltage than the XDA II requires (something less than 5.0 Volts, mazbe 4.7?). I can't check this here, but if someone with a similar problem could measure his charger voltage using a multimeter, we might find an answer. Pins to check on this site under "connector".
If this is the cause, it won't help me here, but at least we'll have the problem solved.
2) I noticed in my charger, that the USB/pins 2 and 3 ( Data-H and Data-L) are unconnected. Potentially the XDA II has an issue if these lines are floating whilst power is applied to the USB-bus. I don't know if we can check this easilz,bu if someone has an Idea?
Greetings from the Maldives 8) Sun, warm, great, but no power for my XDA!!!

I'm using a nokia charger, and the supplied adapter and it seesm to work fine.
MDA/XDA II Pinout - Charge Issue Resolved!!
Being back from my vacation, I immediately got into figuring out why my third party charger was not working, though the MDA II would charge through the same cable when connected to the USB-bus of a PC.
It was a wiring error in the USB-cable after all!
To figure it out I took that little adapter that comes with the original charger apart. Though the MDA/XDA II has the same pinout as the MDA/XDA I, there is a major difference in that not all GND pins are connected together inside. In order to charge, at least one of Pins 16,17,18 must be connected to ground. The grounds on pins 2 and 5 are not connected to the internal charge circuit. TO make things worse, the MDA/XDA detects an external charge power source when pin 2 is GND and Pin 22 is +5V - so the light goes on, but it still does not charge.
On my cable the USB-shield was connected to pin 18. When connected to a PC, the shield was connected at that end to Ground and all went well. On my charger supply, the shield was not connected, so it couldn't charge.
I just rewired the connector and see there it works!
So, if you have the same problem, and are handy at the soldering iron, there is a solution! For those making/selling those USB charge/sync cables, get it right the first time!
Is it safe using a Nokia Charger ?
My Nokia travel charger is rated at 6.2 V, not 5.0 as the one supplied with the XDA II
Regards
Michael
Yeah! But watch out anyway because the volatge is not the only thing to check before charging a device. The right voltage but a bad amperage can cause lots of damage...
Using the Brando USB charger woukd actually DRAIN the battery when the bar reaches yellow....
Using a Nokia charger
The Nokia is rated at 6.2 V 720 mA, the original charger is 5V 1 A.
If I understand my physics right, the XDA may draw more current that the charger can handle, so AMP vise, the danger is on the charger ?
Not that I belive that the XDA would really pull 1A, but you never know.
It would be really nice to have just one charger in the travel bag..

Suggest a USB Charger and source.
Can anyone suggest a usb charger cable and source in the UK for an O2 XDA 2 as the one that I have currently does not charge at all despite the light saying so.
xda ll charger
hi
you may get a car charger from http://www.expansys.com/product.asp?code=108736
i have had one on order for 2 weeks now may get it in the end :lol:

This was the effect I had. Its a mistake in the wiring on your cable.
Thanks,
What I am really after is to find out if there is a place to find a USB cable that will work right out of the box/dodgy package that it comes in. I am not good with soldering irons or electronics and would like to buy one that is wired up correctly to charge my XDA II.
Cheers.
I was wondering if you hardware gurus out there were able to make an adapter that plugged into the port on the XDA II back pack and then accepted the standard XDA II USB charger plug so that the back pack could be charged separate from the XDA II itself.
Anyone?
Ed
What port is on the back pack. Is it juts a two pole jack plug the same as the XDAII Sync Cradle? If so why not use the supply from that?
The port is the female equivalent of the internal bus port positioned below the battery of the XDA II. You can see it when you remove the battery cover on the rear of the unit.
It is very different that the USB port at the base of the XDA II.
Ed
Ah sorry, I had imagined that it would also have a seperate charge jack on the rear in the same way that the dual PCMCIA backpacks jackets for the iPAQ's used to have to allow charging of their internal battery.
Yeah I wish! I used to have one of those iPAQ jacket/sleeves too and it was good to be able to charge them separate from the iPAQ.
So that's the main downside I have with the backpack. I love the unit, the presentation software works REALLY well, but I have to have it fitted to my XDA II to charge it.
I guess if I had a wrecked XDA II I could use the internal socket and make up and adpater. Perhaps in the next model?
Ed
yes, only by short circuiting the x and the 4 pins start a FAST recharging on regular USB cable.!! i recharged my athena, in my car, with a modified USB cable 20% in 50 minutes! before modifying the cable all i was able to achieve was 10% in 3 hours!

here is a short "how to" with pics at: http://picasaweb.google.com/whvoltage/USBCableMod. i took no responsibility for any damages caused by my tutorial. i did it and it worked.
1. peel with a knife (watch yr fingers!) the molded plastic.
2. remove the metal casing with a small screwdriver. start from the part that holds the cable after this gently release the 2 parts parts of the metal casing.
3. it's time to release the contacts.
4. clean the contacts with alcohol (don't waste good wisky) for a good and fast welding.
5. the delicate part is to create the short. be fast, underneath the pins there is a relatively thin layer of plastic.
6. done.
7. rebuild the casing.
no syncing after this modification. for syincing you''l have to use an unmodified cable.
now for the real funny staff: after finishing i realized that i did it "the hard way".
why? i did it on the small and very delicate end of the cable. i am sure it is much easier to do it on bigger, wider end. i am an electrical engineer and i once upon a time i learned that a cable shortened at one end will be shortened at the other end also. i laugh at my self for about 5 minutes......
next step: an universal cable that is charging and syncing and works with my athena AND with my trinity. how? i'll add a toggle switch (this time at the wider end, hehehe).
to be continued....
Great mod...
though I actually use a diddy usb car charger made for a motorola that has a quick charge system built in. This does the trick for me with out the risk of me blowing up my Ameo and car as I am crap at soldering!
Plus 80nok here in Norway is a bargin (about 15usd)

i also tried in my car a Motorola cable. no success.....
yes, there are special cables (found one that actually has 2 heads, one sync one for charging) but they are not available in my country.
athena did not "made waves" here....too big to carry...
i bought one, second hand only for my car. when i walk i carry a trinity.
the athena will be mounted in my car (beat the hell of all the navigation/bluetooth devices sold for cars).
and btw, my athena was charged from 5% to 10% in just 10 minutes!
Oh I!
Forgot to mention that the connection was very loose from the Motorola charger and after a small sqeeze or two from some pliers it fitted great. When loose the charger worked on rare occasions. After the squeeze it charges all the time and bloody quick too with no visible side effects.
HTC wall outlet charger
I have made measurements in my wall outlet charger which came with HTC Advantage X7501 and can confirm that there is short circuit between pin X and pin 4 (GND). So, looks like Advantage check this for FAST charging.
My soultion to the charging issue is I use an inverter and a wall charger from my kaiser and this works fairly well. before that the car charging kit would not even maintain the charge if gps was running.

Since I have gotten the Epic I have had so many issues with windows seeing the phone and installing the proper drivers even right after restarting the phone. Im lucky if windows see's the phone one out of 10 times I have to plug unplug etc etc until my pc's see the darn phone.
So I caught a post earlier that suggested to try a different cable and BAMM!!! phone links every single time no issues. Im using the usb cable that came with my evo now. Just side by side you can see the huge quality difference.
Samsung might want to check these cables and I suggest if your having charging or communication problems with the phone to try a new cable.
Let me know if any of you are also able to reproduce this!!
Yes. My cable actually broke the 2nd day of owning this phone because it was tugged on a little too hard while i was using my phone with it charging. It wouldn't charge the phone unless it was being pushed upwards or held a certain way.
Pathetic.
I've since been using my girl's MyTouch 3g cable and have had no issues whatsoever.
I just purchased a few new cables from monoprice. I've always had awesome results from them and they are cheap.
Yes the cable that comes with the epic should not be used with a computer IMO. Just look at the charger that plugs into the wall and compare it to the USB pins on your computers case.
The pins are raised a lot higher on the part that plugs into the wall compaired to how raised the pins are on my PC's case. I'm running an antec 1200 and I would consider the front USB ports to be really "tight". I then tried a different cable and have had no problems.......OTHER THAN BATTERY LIFE IN GENERAL sucks on the epic.
I didn't Realize there was a problem with the usb cable on th
e computer side but I have been using my I mac since my pc took a dump b. i think the phone end of the usb cable is just crap.it seems to disconnect really easy and not near as robust as the one that came with my hero. Still love my epic though!

Come on. Both the cable and the wall unit sucks. A phone that is 500 bucks and you give me a .7 amp charger and a cheap ass cable? My HTC touch pro came with a 1 amp charger, that looked nice, and came with a good cable.

Right? Well at least we got 16g sd cards. They have to give and take you know? lol
my cord works just fine.
However i only have one mini usb (the one that came with it) so i ordered some micro usb to mini usb adapters so i can use all my old cables.
Just order a bunch of microUSB cables from monoprice. It's like $1.20/cable. I ordered 7 so I have a large collection of easily lost cables.
How the hell did I not know about this site? THANKS
My HD2 USB socket is buggered, it won't charge unless I get the cable in at a certain angle. It's definitely not the cable which is dodgy, I've used three different ones and they all have the same result. This means I can't sync Android with my laptop.
Any way I can disassemble my phone to repair or replace the USB socket? Any guides out there? Thanks.
I googled repair HTC HD2 charge port
And got pages of stuff
Same to me. What's happened is the port has come away from the main board. Just needs soldering.
I don't use usb to sync so I bought a mains battery adaptor for charge.

Just needs soldering! I'm afraid for the average joe trying to solder the micro usb connector pins back onto the pcb is no easy task. My reccomendation would to leave solder out of it, you'll likely short something or get solder spashes all over the place.
Get the finest soldering iron tip you can, a magnifying glass and just press the pins back onto the pcb pads.
TO be honest this is very poor design by htc, that socket should have been reinforced, using solder to hold sockets down is just terrible cheap design.

Agreed, absolutely POS design. I had my HD2 less than a month and my usb broke.
I didn't have the guts to try and re-solder it, so I got me an external charger, spare battery, and started using things like dropbox, email attachments, and micro-sd to standard size sd-adapter more.
I never had any problems with the mini-usb's, but it seems the micro's are alot more delicate

Technicaly the mini has a much lower mtbf. the micro issue is that folks try to put in in the wrong way up as its harder to see, so spend effort pushing the socket off not connecting to it
I have dropped a red blob of paint onto mine and now the problem has gone.
The Mini was a far better connector. Easier connection, stronger, more pins & already in huge use. introducing & standardising to the micro was madness !
Yeah, I use an external charger and unplug my battery to charge it, but it's really not very practical. I was using an app called 'Sleep as an droid' which is a great alarm clock app but I can't use it any more because my phone just runs out overnight
I might give it a go, but I really don't want to damage my phone any more

There is a store in south Wales that will soldier it back for about £20 thy google
I got a spare battery and an external charger. I just swap out the battery once it is empty for the spare which is fully charged in about 1-1.5 hrs.
I also use a card reader for large file transfers and samba for smaller ones.
Fortunately, when the port died, I had a 420MB partition. So I can still flash most android Roms.
If any of you know anyone who fixes the HD2 in India, please let me know.

same issue ... this micro USB is not working anymore.
I have two batteries and an external charger.
I do not understand your last point: how do you flash without USB ?
atomebr
Transfer ROM to sd card, flash using cwm.
