hi, Just have to tell you about a weird fault with my XDA2. Last november I dropped my XDA2, and it was replaced under the Silver insurance that O2 offer. Since receiving the new unit, I have had random Hard Resets due to a totally discharged battery. I changed the battery but still the same problems. I had to check my charge level very frequently and put on-charge to prevent wipe-outs. This morning I noticed that as I put my phone in my pocket it was vibrating very weakly. It would stop if the phone was turned upright, or laid flat on its back. If the phone is placed on its left edge and given a slight tap on the connector end it will start to vibrate, whether the unit is off, on. Ah-Ha, this must be the culprit. The vibrator is very battery hungry even though the vibration is weak. I have sent it back for repair. Really pissed as I have to use my old nokia 3650 till it comes back! :evil:
Anyone else had this problem. Clearly a short of some kind....
Jerry,
I have had this problem recently. MyXDA2 is secondhand so not sure of its history. The bottom of my unit kept getting very hot, very worrying. I narrowed it down to the vibtator, which is now electrically disconnected. Watch this spot to see if it is curred.
Fred
Hi Derf. My XDA2 didn't get hot, but I reckon there is a weak spot regarding the wiring of the vibrator. In my case it may be shorting through to a low current track causing the motor to run, in your case it may plain shorting out. Not nice at all. I would have tried to attempt a repair on mine, but it is insured and I didn't want to invalidate the guarantee. Good luck with sorting yours.
Jerry,
Just an update on the vibrator problem. It has been about 4 weeks now and I've had no probs at all. I will investigate if it is a PCB problem or vibrator fault. I suspect PCB as I have never turned the vibrate function on on purpose.

Hello all,
I recently dropped my phone and when I tried to turn it back on, it wouldn't turn on. There's no light on anywhere in the phone. I opened up the phone and checked all the connections, seems like everything is still intact and connected. I have given up on trying to diagnose the problem on this phone, so i'm asking y'alls help. Could it just be a battery problem? or is it a hardware problem that's unfixable? Can I send this phone somewhere and get it fixed, if so, how much would it cost me? Thank You in advance.
Its more unlikely for the battery to get damaged on drop down. Its definitely a hardware. Hope your baby is still under warranty, the you can even get a replace done for free. Else the charge may vary by the diagnosis. Anyway i hope it wont be of much expense if the display is intact by the dropped force, probably there wont be of much damage.
Regards
Carty..
Hi,
I had the same prob. & send it to the service center. Luckily they replaced my phone for free. Still don't know what the real problem was, very unlikely the battery though cause I got it back with a half charged one (probably mine which I had to send in as well).
No good news for you afterall, I do really feel with you in these horrible times.
Regards, M
Yeah, i'm thinking of just buying another phone, because I don't have warranty on this phone anymore and even if I did, I have voided the warranty on it by opening it up. I'm still gonna get a new battery for it though, just to see if it is the battery, if not then I guess my loss. Atleast I found out that it wasn't the battery.
Does it show evident marks of being opened up by you? Cause that was the main reason I didn't try opening it, too afraid voiding the warranty. Though I had it unlocked & patched for BS too.
So I just gave it a try & in my case it worked out fine.
Refards, M
I suppose, problem is connected not to battery, but to battery cover/switch. Look at the photo: there is a pin on the battery cover. Usually, when cover is on the right place, it presses the switch down. Try to check at first, if switch is broken or not. When pressed, it have to short circuit. You can just short it by piece of wire and see, what's happened. If swich is not closed, jam will never turn on, even if you have charged battery, or AC adaptor connected.

I tried that already, but I will check the cover and see the latch on the battery cover is broken or not, maybe it is. I'll try it when i get home.
if you want to salvage it for parts, I'll buy the ear piece (mini speaker in the front) from you.

I'll have to wait and see first, maybe my phone can still be saved.
Oh man, i'm so relieved right now. This whole time I was wondering if I had to buy a new phone, since my jam is broken. I just found out that the US service center for HTC is located right by my house. It's just a relief, I will stop by there office on monday to see if they can fix my imate jam. Thank god !
Hope the best for you @ very low cost.
M
dropped off the jam there this afternoon, the cute lady service tech took my jam and said she'll run some diagnostics on it and call me whenever she gets done with it. Hopefully it's fixable.
How's it going all?
My phone has slowly been dying on me, and today was the final straw. I shut the phone off last night, and it will not turn back on. I've tried using a house/usb/car charger with no success. Would I be wrong in assuming that it is a faulty battery? Could there be another problem? The furthest screen the phone reached today was the tmobile white load screen, before turning black and shutting off.
If it is the battery, would this be an appropriate replacement?

It does sound suspiciously like a dead battery. Try cleaning the contacts on the battery and phone first. If that still doesn't help, and if the phone hasn't been damaged (you didn't share that info), then you may want to get a replacement battery. The one you linked to would work fine.
Another battery option for you.

There is no apparent damage that I've seen. I have had a problem with the phone losing service lately, along with a crackling sound during the start of a call.
Before I order this item, are there any retailers that would carry it? I'm leaving for a week and wouldn't have this replacement in time.
Thanks for the replies!
Check your local Cingular stores -- I don't know if the 8125 battery will fit into a Wizard 200 device (e.g. Qtek 9100), but they should be electrically identical.
I just ordered a replacement battery from amazon.com after trying a battery from a friend....and the phone worked.
I tried one last time to get the phone to charge, but to no avail...UNTIL I seen the orange light after wiggling it around for a bit. The phone made it to the loading screen, and then the light, and the power-up disappeared. I've been trying to get the light to come back on, but I can't seem to get that sweet spot.
Does this sound like a problem with the usb port? If so, is there anyway to fix that?
Thanks!
i have a HERM200 and ever since i bought it it had a heating problem. i've noticed that the only thing that causes the phone to get hot is the gsm antenna(calls,edge,3g, anything using the gsm band). i'm using the battery status plugin and it shows that the wi-fi , bluetooth and camera functions don't use more battery power than they're normally supposed to. i've tried this on both a new non-htc battery and the batt that came with the phone, and they act the same. the phone is not new and i don't have a warranty. i run Schap's 4.30 ROM and 1.54.30.10 radio. i tried several other rom/radio combos, but the problem didn't go away. Please Help
some people neglect to understand the fact that these things can bang out 5-20 watts of transmission power, most of which is deflected away from your head via antenna design, and yeh when things run like that they will get hot! quite litterly, as i have noticed that several wireless 802.11 devices (psp's etc) will get warm to hot near an antenna!
this will mostly happen when the transmitter is at maximum output and most 802.11 devices run at around 2.3 to 2.5Ghz which dosent help being near the microwave 5Gig band!
if it makes you feel any better mine runs hot as well during calls and using the wireless networking, its normal
read more carefully. i said that the only thing giving me this problem is the radio antenna. when i'm using the wi-fi antenna or anything else, it doesn't even get warm. but using the radio antenna makes it hot really quick, and makes it start eating a lot of battery power, from 300 mA up. when i end the call the phone remains hot, and my battery goes from 100% to 0% in about 2 hours. so it's clearly not normal
have you tryed to reset the phone after making a call? (just as a test) mainly to see if that forces the GSM transmitter off, it sounds like its still transmitting at full power after you make a call.
this could be caused by a hardware failure or a shorted link either on the board or under a SMD chip, could even be a dirty connection to the antenna.
i have seen the primary cause of death in most electronic equipment is a build up of dust and moisture, it might just be an idea to look up the instructions to dismantle the areas affected and clean them with isopropyl alcohol, and for the love of pete dont use metho, they put impurities in it to make it taste bad for certian reasions, which will leave a bad residue on the boards.
if you do try that, remember to leave it sit for half an hour to let it fully vaporise, the last thing i am sure you want is a explosive Hermies.
hope that heads you in the right direction for repairs, other than that i cant see any thing else short of replacing the transmitter board
btw: i was just using the wi-fi transmitter as an example, but staying hot after making a call is not a good sign, it should cool down
thanks. i will give that a try. hope it sorts things out.
its not hard to understand that if your phone is not stopping to give full power after a call. You know the classic thing, when you are near a TV or a radio, phone causes strange sound when its near. Just go near and see if your phone causes this strange sound after a call (when you made a call but hanged it up).
also open and clean your hardware with very soft tiny brush for dust and chech your antenna connection. My hermes doesnt get hot anytime, even at charging it doesnt get hot, only very very little warm on battery side.
i've charged it completely, it obviously got really hot. usually at this point, i would take out the battery and let it cool off before turning the phone on, otherwise it would get even hotter and eat 300+ mA and drain the battery fast. this time i opened the wi-fi connection and immediately the battery status dropped from 332 mA to 130, and stayed down there. the phone even cooled down a bit. after i've turned off the wi-fi, it started draining and heating again. what can i do? is it a software or hardware problem? i'm using schaps 4.31, 1.47.30.10, have google maps, palringo, opera, tcpmp installed
it seems like a similar problem i had where a shorted capacitor on my FCB, when it switches on and off different circuits its bypassing the faulty component,
not much could be done without a circuit diagram, but certainly the heated component would have stress marks around it related to the heat, look at most of the solder joints through a powerful magnifier glass, or microscope, even if the phone is apart try to touch locate the hot component, thats a dead giveaway but is the most dangerous way to also do it cause you can short out components. yeh you have to try to power it while its in bits!
for me when i found the shorted capacitor i simply removed it, it had got so hot it practically de-solderd it self and i never botherd to replace it since it was only to provide filtering to the FCB leds,
if your unable to locate the faulty component it may be time to source parts from someone who has bricked one or is updating.
i know its a big ask for a microscope, but just about any will do, mine is made from an old slit lamp (eye examination tool) that was being tossed out.
Hi to all, my g1 does not turn on by any means..I have done everything from CPR to dressing in aluminium under a thunderstorm today in NY. if there is any way I could resuscitate this device, I will be very thankful.
does anything happen while the charger is in?
nothing at all. not even the led turns on when I connect it
the battery is probably dead
tested the battery on my other g1, perfect. the other battery on the damaged phone, Nothing.....
Sounds like you may have experienced a hardware failure of some sort then. I would suggest contacting HTC about doing a warranty RMA.
I had the same issue with a G1.
Pull the battery and look at the pins. Use a device to straighten and even out all the pins. While doing so, make sure to short all pins together. This should clear out any remaining stored power in the device.
The pins in my device were only slightly uneven and this brought the unit back from death. I'm not sure if the connections to the battery are fragile or if the connectors to the pins are what went bad. However, give it a try.
Jon
My guess is
The motherboard short circuited. I fix G1's as a side job/hobby and I have come across a couple G1's where it wouldn't turn on what so ever or give any sign that the G1 still had a soul. The reason this happens is either that the g1 was dropped, causing the motherboard to short circuit or the g1 got partially wet inside/humidity and when you connected it, the electricity started killing your phone little by little until it was completely dead. But either way my guess is that your motherboard short circuited out. HTC will repair it but for about $160 I believe
I am having a similar problem. Mine turns on, but shortly after will black out. Seems to mostly stem from pressure or contact with the lower portion of the phone where the buttons are located.
I had a problem like that. I just called T-mobile, and they were VERY cool about it and fast. I think I was on the phone with them 10 minutes. They sent me a new G1 for free, they even paid the postage to send it to me, and for me to send it back to them. Just make sure on those 2 with dots under your battery none of it turned red. I did the same thing with my daughter's sidekick and there was a small bit of red on the white dot and they charged me 100 bucks. They said it would take 7 to 10 business days to come and it was at my house in 3 days.. not bad eh?
I have a problem with my Axon 7 (global). Ive decided to change battery on my own one week ago. I was super carefoul with every step i did, no cracks, no damage. I assembled everything togeather and suddenly no signal. Wifi worked perfectly. Now i have this often signal looses which persists even after reboot. Sometimes when I finally catch signal it shows me almost full 4g+, but on the other hand everythig works very sluggish. Super slow internet speeds, even for messeging via whats app for example. I tried to check if this is maybe some software issue. I was on global B03. I could not update to B04 via ota so i decided to downgrade, then install b04. I did, and this solved nothing. Problem persists and phone without wifi is unusable :/ Any ideas how to solve this?:crying:
Connector not seated properly inside it?
I also replaced my battery. The battery behaviour is now normal again but seen no differences in how it runs.
I think that it's not that, I've payed extra attention to this second time that I opened phone. All the connectors I've unplugged, then plugged it again, checked antenna as well. No visable damage to the cable or the connectors.
Thinking about my experience doing the battery, the two most difficult or potentially damaging things were separating the rear cover from it and getting the battery out. Once the cover separated it came off well. It was a hard job getting down under it. The battery was hard to start lifting but with isopropyl alcohol under it, It came up easier the more it was lifted. Maybe something around the battery has been compromised.
Thank you for your response. I did not use alcohol to remove battery, i used hairdryer, and i began to remove battery from other side (the one with antenna). Maybe i burned antenna? Is it possible? Sryly no visible damage, nothing! Everything else works. BT, Wifi, all functions - only signal problem. Any idea what part should i change? I also founded some info in iOS forum somewhere, supposedly iPhone 6 or 7 had similar issue when someone changed battery. They suggested to unplug battery and hold every button for 30-60 seconds, one after another, to "discharge components" or something. I dunno :/
You change the charger board too?
I ordered from Ali only antenna, should i order charging board as well? Anyway, why charging board? Is there some important components that i could have damage? Why not motherboard as well? Antenna is connecting charging and motherboard together. Just wanna know why do you think that i should change charging board as well, maybe Ill learn something new
