Hello
in the last few weeks i got some emails of ppl who had problems charging
their XDA's. So i decided to redo my Mod and make a few new pics.
First of all it seems like XDA Charger can't filter fluctuations in the powerline hence the fuse that is supposed to make sure your XDA wont be fried blows and you cant charge it anymore.
The fuse itself seems to be a 1.5 AMP fuse, unfortunatly i wasnt able to get one of these babies in...i could have used the 3.0 AMPs but i thought it
might be smarter to stick with the specs.
So where to get it from? Fortunatly i discovered that the same fuse is
built into the XDA twice. The second one is responsible for the extended battery pack, which i dont use. Perfect for my mod
Please DO NOT do this if you dont know anything about soldering.
I was just lucky Just call and expert...most will do it for free or charge a small fee.
@Peter Poelman : i hope you like this one better
Okay...lets start with the pics...
its upside down...lol
lucky the ones who preview
sorry for that
Before i forget...after this mod you should not use an extended battery pack anymore....i bought a 1800mAh battery from expansys.
which lasts me for 7 hours hard PDA gaming fun...
Aquasesh,
Your post will quite probably save my day as I have pluged the wrong cable in my XDA.
But I'm quite unclear on the exact order of your picture. I've seen it's been posted in reverse but I'm still confuse.
Could anyone put numbers instead of my X so that I can next search a techni guys to have him do it for me.

Tanguy
Ignore the bottom picture, then read right,left, right, left, right, left.
Where's the blown fuse?
I know it's been a while since you must have done this but how do I get the top cover off. I unscrewed the one black screw I could find and managed to get the 4-way cursor button out but I don't see how to get access to the front to do the soldering.
Thanks,
Daniel

after solder the wallaby fuse...don´t work
hi
I have solder the fuse one month ago...and works fine...now after charge in my car the wallaby stay´s off...try to solder the fuses again...but nothing.
Is my wallaby dead?
to all
better replace fuse with same value,not bigger or with wires,and check your charger,maybe voltage is too high.otherwise you'll damage your device.abnormal voltage input may fry your xda.
hi
one month ago i have solder and dont put a fuse...whne i charge in the car the led turn off and never wake up again...so may be my wallaby is dead now?
there is any thing i can do to put my wallaby work?
or i have to buy another PDA?
please help me...what can i do?
i again...nobody help me?
can i do something to solve this problem?
don't know what to say,remove battery,let him without battery some time few hours or more,search for another charged battery and try again,maybe only charging part are damaged.
i don´t have another battery...is built in...i gone try discard from wallaby few hours...
another adivece?
manythanks
Hi
I removed the battery a lot of hours...and nothing
anotther sugestion please?

Just performed a battery test in the xda system diagnostics. It shows that my xda is getting no charge!
Checked the supply for output and that is ok :shock:
Anyone else who has got charging/battery problems give this test a try.
Just go into wallaby boot loader (press soft reset and power button at the same time). When it loads press the action button and diagnostics will be loaded. Navigate down to "battery" and press the action button again.
There are several codes displayed but i dont know what they mean. On the "charge" section it displays "ERROR !!"
Does anyone know what is causing this to happan and how i might fix it?
Got to a stage where i have tried everything to fix the damn peice of crap and will throw it up the wall soon
Anyones help would be greatly appreciated. Thanks.
I have looked at that, when plugged in to charger it says Main voltage0x0261 Ext voltage 0x0000, Chg voltage 0x0000. Vos FFFF, Rob 0270, mine is chargin ok though. Have you tried another battery? I am selling a battery from an xda I am breaking, dont throw it up the wall it wont do it any good at all. I did see a few things about this on this site, and also diagrams that fixed the problem if indeed it is a broken circuit.
Thanks for that info and checking yours out. I havent tried a new battery yet cos i am conviced that its something else.
A few people i have spoken to have the same problem and they have put new 1800mA batteries in. Still the fault remains. I have also seen on this site someone who has bridged a wire over one of the fuses. I didn't really want to resort to this yet!
I have literally spent hours on this site for a fix for this problem but found nothing that has worked for me so far.
Do you know of anymore links that i haven't mentioned?
Here's what my xda lists on the diagnostic:
CHARGE STATUS:
ERROR!!
Main Voltage:
0x01F0
Ext. Voltage:
0x0000
Chg. Voltage:
0x0000
VOS: FFFF
ROB:0000
Thanks for your help cruisin-thru!
I know this is obvious but I take it you have checked it out using another cradle/charger/usb sync/charger.
Yep. Got a friend of a friend to lend me his cradle. No good though!
This might help...
There's a guy here that fixed his non-charging XDA by wiring across a small fuse.
http://forum.xda-developers.com/viewtopic.php?t=4811
I saw that one thanks pete. I haven't had the bottle to do that yet though!
I was thinking maybe as a last resort! What do you think?Do you think that it might damage my xda even more?
The bloke who fixed his said it works ok. Fair play to him in having the guts to do that. Have you seen how close all the components are together?
:shock:
Oh well if all else fails!
You really need a thermostat controlled tiny tipped soldering iron for that job, dont risk it if you dont feel capable, however if you did the job of taking it apart, locating the point that needs bridging etc, I am sure a local small tv repair shop owner could do it in 5 minutes, offer him a few quid for doing it while you wait.

I think holding a multimeter over the part to see if it conducts is unlikely to do much harm. If it conducts, no need to solder. If it doesn't, nothing else will help.
Does anybody out there know what may be wrong with my wee Wallaby? The battery fuse is gone, so i've jumpered it out but despite the battery voltage being 3.5v the unit wont start at all. It doesn't respond to any reset and I cant get it to enter bootloader mode. Any info would be appreciated, i'm an electronic engineer and noticed there are quite a lot components involved in the battery circuit.
Thanks.
Buy a replacement on ebay for 10 us . LOL Upgrade your wallaby its olddddddddddd
Yeah, i've ordered one already! I was unsure though if this was going to be a waste of cash. A whole £13! I'll let you know how it works out. Thanks for the reply.
I think you have probably fried the logic on the battery. As for upgrading, I think the Wallaby is the best value pda/phone available anywhere.
Hi there,
Got my new battery and low and behold it has brought my Wee Wallby back from the grave! The battery IC's must have been faulty, there's five pins on the circuit board for the motherboard to connect to so I reckon the battery logic is quite sophisticated.
Thanks for the help guys, I tried O2 in Glasgow but they didn't want to help at all unless the XDA was a warranty job.
I've also upgraded my ROM to the one and only XDA Developers special and I have to say it's a real improvement all round.
Goodnight gadget lovers!
Is it possible to power an HTC HD2 without a battery or the back cover? I found one about an hour ago in my downtown area, missing a SIM card and missing the microSD card. As noted it doesn't have a back cover or a battery, so my intention was to attach a "standard" 5V/1A cell phone battery charger. I figured out from a picture of the battery that if I've got the HD2 flat on the display and I'm looking at the back, the positive terminal will be the one on the left but, when I attach the power supply (which I tested before this attempt, it works) leads using micro-alligator clips and push the power button (front of display, button furthest on the right, I think, never used one of these HD2's before) I get no response.
Now, the question is either a) am I not getting any response at all because the HD2 can't be powered up in this manner because there's no back cover or b) it's more likely to be completely toast because of the damage it apparently suffered in the drop that shattered the glass. The only damage (aside from the glass) is a very tiny scrape/scuff mark on the top right corner of the bezel - obviously that's where it hit the ground.
I don't own any of these apparently micro-USB style connectors (or is it mini-USB, I can't figure out which is which I suppose). Bleh, I just looked at a pic I found with Google Images, apparently it IS a micro-USB connector.
All blabbering aside, even if I had such a connector or a power supply using such a connector, is the phone going to even power up without a back cover on it or battery inside? I know a lot of devices become totally disabled when the back cover is removed (as my Dell Axim X51v does; as soon as I even throw the lock switch to unlock the back cover that disables the device totally.
Anyone able to provide some tips or suggestions? I have no way of knowing who it belongs to so I'm claiming it, and if I can verify it might work or does still function I might be willing to put some money into getting the glass/digitizer replaced, a new battery, power adapter, etc.
Anything at all would probably be quite helpful.
Thanks...
The HD2 works without back cover!
The HD2 doesnt work without battery...!! I've never heard of a mod to enable switching it on through micro-usb.
Be carefull you could be scammed...buying a phone in that state, because of the hit some other components may be damaged!! It depends on the price and money you're willing to risk!
no problem with powering on without the backcover. did that many times before.
but i guess its not possible without a battery...
DN41
Ah, ok, so the fact that there's the two metal 'dots' on the HD2 that apparently become a connection when the metal battery cover is in place don't affect powering it up, but no battery keeps it dead? Hrmmm...
Ok, if someone that owns an HD2 can confirm that it becomes very useful info. Take the back cover off, take the battery out, and tell me if plugging in a micro-USB cable (either from a computer USB port or from the AC adapter) allows it to function at all, and then try the same thing with the cover on (don't put the battery in, however).
So there's 3 possibilities:
1) It'll work off the micro-USB power with no battery and no cover
2) It'll work off the micro-USB power with just the cover installed but no battery
3) It'll work off the micro-USB power with no cover but with a battery installed
and actually the fourth possibility which doesn't matter in my case:
4) It'll work off the micro-USB power with the cover and the battery installed
Dammit I hate it when I find stuff like this and can't get it functional.
Again, thanks for any suggestions - and I didn't buy this phone, I found it a few hours ago, on the ground as I was walking home. I wouldn't buy something in this cosmetic condition unless I knew it was working even in spite of the cracked glass. I've owned iPhones with horribly shattered glass on them but they still function, even all the multitouch functionality is still working - that's my hope here, that this device will still work just fine and if it does then I'll pay to replace the glass/digitizer.
Thanks
Edit:
I think I just realized that the metal contacts on the inside of the back cover and those 'dots' could be because the HD2 is using that battery cover as a Wi-Fi antenna, plate-style antenna.
I just tested it for you. Without the battery in there is no starting it, period.
Might I suggest though that you ask around and find a mate with a microUSB, (you must have someone that has one), and plug it in when the battery contacts are jumped. It will probably work that way. I'm not going to try it because I have a perfectly good phone and have always mistrusted elec-trickery...
those spring loaded studs have been the subject of much discussion, with no definitive answer,, stop the cover rattling, grounding plate for the antenna, remnants of an unreleased car kit,,, who knows. certainly signal doesn't appear diminished with the cover off, and on the inside of the cover there is no coating on the metal where they connect, indicating a signal being passed so who knows.
i suspect simply attaching power to two contacts isn't enough because the third contact is expecting a signal of some kind? perhaps a connection from the battery charge protection circuits?
you could always buy a cheap copy battery from ebay, and just resell it if it doesn't work, or run a scam on your insurance with it? (did i just say that out loud??)
I'll say this again: I found the phone on the ground on the side of the street while walking home a few hours ago.
I don't use T-Mobile service and I have no intentions of using it as a phone; I already have a phone so I was going to use it as a portable media player sorta like an iPod touch if I can verify it works 100% and just needs a battery/back cover/replacement glass and digitizer. That's my intention at this point.
And I was thinking that yes it won't work at all without a battery so, thanks again for the info. I'll head out this morning to a T-Mobile store (actual T-Mobile and not a reseller) and see what they can tell me. Surely they'll have a battery/back cover and potentially an AC adapter to verify if it's 100% dead of somewhat functional even in spite of the busted glass.
Let's hope it works...
what about searching the owner?
DN41
Well, let's see:
- I can't power it up
- It has no SIM card
- It has no microSD card
- The only way to track the owner would be using the IMEI and I'd have to go to a T-Mobile store to do that, when that's done and they get the number, if the phone was stolen and then dumped in the trash/on the street where I found it, they call the police and I get in a bit of trouble for no good reason
That pretty much covers it.
okay, you're right...
i cant imagine how it landed there...
who would throw it just away?
sure that its a real phone and not a dummy?

Well, Yeah, with an iPhone 4 what else WOULD you do if you don't want the surgery to be able to use it! LOL
Also think if it was your phone! I'd be absolutely gutted, and very glad to get it back. But maybe it's unregistered (through the IMEI) or not been reported as missing.
In the UK (don't know about elsewhere) if you report that you found something to the police (I found a £50 note) and no one can show that they own it then it's yours after about 28 days.
Unless you have really dumb cops then you shouldn't get into trouble if you take it in!
On the other hand you may find the battery and/or cover if you look carefully in the area where you found the phone.

I think those contacts are just to ground the back cover to stop it causing interference. It doesn't seem to affect the phone if I don't have it on or am using the plastic cover with my big battery.
On a similar theme, does anyone know if it is possible to power the HD2 from the micro USB supply while I swap batteries. I don't want to have to do a soft reset which loses what you are doing. But I'm worried that without the battery to absorb the power there is a risk of damaging the circuits?
I don't want to just try it because I already blew my main board by powering the USB through a cheep adapter and a Nokia charger that supplied too much power and had I to get it repaired/replaced. I'm hoping someone already knows

Long sad sad story short:
Bricked my Flyer to the point where it didn't boot up, had wrong radio roms and in the end, the battery died.. now it just blinks orange..
HTC Repairs said that the motherboard needs to be replaced, which I find very hard to believe, since it worked just "FINE" before the battery died
In my search for a Battery for the device I only came by chinese bulk sale pages, 100pcs minimum order.
Would be very grateful if anyone can point me to a page or person who can spare a full Flyer/Evo battery, or better yet, who knows how to manually charge the battery, if possible, using a power generator..
(And yes, I did a search on the forums but no clear lines of help in my question)

Thanks, ordered a new battery for 29$, will see if it works
is it orginal battery?
when you get the battery can you inform us about the new battery's performance?
there is a a post on how to manually recharge battery; search a bit XDA; Globathron posted solution for a guy with same problem.

OK, i got a desire x off a friend he bought it new two weeks ago but he went on holidays and i swapped him an iPhone.
The phone is unrooted. Last night i sat down while it was in my pocket and my car keys cracked the digitalizer. I was extremely annoyed so i left it down on the table. I had installed a new android launcher team that day but when i had the phone in my hand after it broke i remember the battery was a red icon, but i was low im just mentioning. Anyway long story short it went dead i brought it up to my room and plugged it into the wall charger. The orange light came on so i went to sleep. I woke up and the light was still on. I plugged it out and the light went off but the phone still wont boot nor go into recovery, safe etc.. Can someone please help me as i don't know what to do.

First of all, your friend's Desire X is surely bricked. It would take a more direct approach than damaging the digitizer or installing a launcher to actually brick the device.
From my knowledge of electricity i would say the digitizer is short circuiting internally which may explain the reason the electric current from the charger flowing constantly somewhere else other than the battery. This is evident in the fact when we have a mobile device which has almost no charge, and after we plug it in and start using that mobile device, the AC charger keeps the device running and also the screen on, until the battery gain enough charge to take over and start storing charge itself. The scenario seems possible to the extent that your digitizer is short circuiting internally. And it is preventing the battery from gaining enough charge to take over.
The next possible scenario is that the battery has got pushed inside as well. But for this to be possible your car keys have to go through the plastic and reach the battery to be flattened by force internally.
So what you can do is go to any authorized service center and explain just what happened. Of course they would charge you cos this would be out of question to offer warranty. Just replace the digitizer and check.
Good luck.

So if you can get a look at how much damage was done, maybe you can repair the digitizer only and be done with.

My #1 suggestion is for you to take the desire X to an authorized service center and let them repair it.
Because if you do any other damage while trying to take apart the device, it may damage parts which were not damage originally. This would cost you additionally then. So let the repair guys worry about it. As it is you have enough stress i can understand.
Unless you are sure about disassembling the unit yourself, i DO NOT recommend it. The manufacturers are now sticking to new methods of minimizing the size of the body. So this means a lot of glue and other adhesives between the body, lcd panels, digitizer instead of the traditional hooks between the plastic body and screws to hold the parts together. Believe me, removing away glued parts is very risky if you don't have the proper equipment to raise the temperature to certain degree to melt away the glue or adhesives.

As i have seen the internal of HTC Touch, Diamond and HD2 only what i would suggest is for you to check for any damages to ANY other parts of the device. This includes
1. the plastic body
2. the mainboard
3. the battery (by default it should be a uniform surface) so check if its pushed in any sides
4. if the lcd has been pushed from the inside leading to an external mark on the back side.
All the best
**edited**
Just had a quick look through my desire X
There is not circuit board on top of the battery compartment. The mainboard is just on top of the device.
So i am sure it is just the LCD/Digitizer
Hm, there were in fact three reports about similar issues on the German android-hilfe.de forums, where the device actually wouldn't turn back on after the battery had reached 0%, the device had been shut down automatically, and had then been charged as usual. Would be interesting whether that issue was a more general hardware/battery failure, and the physical damage reported here was just 'coincidentally', having no direct impact on the battery.
To be honest, I'm quite concerned about this - I always used to let my old Samsung device shut down when its battery reached 0%, hopefully saving some battery life (although this might also be a myth), and had planned to do so with my Desire X as well, but after reading the mentioned reports (and this one, of course), I'd rather recharge the device even before it reaches 0%...
Maybe someone could shed some (technical) light on this... - the mentioned forum reports in the end did not offer other solutions than taking the device to a service center and have it repaired.

m glad my device isnt like what you said. but i think i proved the point those devices have problem.
would be interesting to know if those devices had same problem after an impact.
