1- it's reboot many times without any reason(I read one thread about it but i dont understand what to do!!)
2-sometimes 2gb microSd card loosing?(i cant open it from phone...only rebooting helps!!)On other devices card works good!
The usual reason for a 3125 rebooting is that the battery cover has gotten worn down to the point that the micro-switch under it is not fully depressed. There are multiple potential wear-down points. The hooks on either side and the tabs at the bottom can get worn or even broken. There is also a raised pad at the lower left (looking at the cover from the inside) than can get worn, as can the contact point on the switch.
Typical solution, providing the hooks and/or tabs are not totally broken off, is to put a thin piece of plastic or cardstock between the microswitch (lower right of the batter compartment) and the cover. It's a temporary solution (it tends to get continually worse), so if this fixes it, you should check eBay for a replacement cover.
That said, I had a phone that reset for another reason, which I never found. So it could be something else. I ended up buying a phone with a bad keyboard and doing a keyboard transplant from my old one.
I had the same problem and I'll tell you what I did. Open the back cover and you will see a little black switch next to the sim card/below the battery. I took a pair of needle-nose pliers and just twisted that sucker right out like a bad tooth (carefully though, you don’t want to tear up the foil on the board). Then I put a small spot of solder on the two contacts that the switch used to connect to. Never had a random reboot ever again. From then on, just make sure you take the battery out first before ever messing with the sim/sd card.
That worked for me.
Thanks

i have the very same problem and this sounds like a perfect long term solution.. any chance of getting picture of ur mod for morons like me who need visual stimulation?
regards,
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...

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?

i was in a thread yesterday where some guy talked about how he dropped his phone by accident whilst 'driving along with it in his hand, with his arm out of teh window', so yea, some people are , , well, insert your own noun here
oh no...how can you hold your arm out of the windows with a 500€ phone in your hand?
i just cant understand some people...that doestn go in my mind...

Not really mate. I found an iphone 4 yesterday and managed to get it back to its rightful owner. Took a couple of hours out of my day but what else could i do?

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

did we ever get an answer as to why that, im going to select the noun "twat" was dangling his hd2 out of the window @ 40mph??
I need closure on that one.....
Ok when you remove the battery there are 3 connectors there. If you put your phone face down the left hand side one has snapped off.
What does it do, can it be fixed? Any one knows a place around London that can do it?
Call t-mobile for a replacement. I've never heard of anyone fixing the pin them self.
I got this phone second hand, it was t-mobile branded but I am not with t-mobile so no go there.
I need HTC repair centre of a sort.
I had a stuck power button and partially pried open my phone to fix it. Now the back cover is loose near the headphone jack and even after tightening the screws there is a gap between the screen and back cover. Any solutions?
Impossible to tell really without having the phone in hand, but sounds like you didn't get something lined up right when you put it back together. Or damaged something when you took it apart? Or... I guess there are a number of possibilities.
Probably take it apart again and carefully assemble it.
You should try factory reset and reinstall your ROM. If that doesn't work, flash back to stock. Then try to put back cover on. May be a hardware issue if that doesn't work.

I dropped my S9+ for the first time today, onto a hard tile floor. It's in a pretty good case, but it landed hard. The phone is completely crack free and 100% functional, there is no detectable damage except that the back cover is now slightly gapped (like 1 or 2mm) on the left side (the side with volume buttons). It will not stay closed after pressing it down. It closes when pressed, but it slowly springs back up.
Should I try applying heat to the back cover and then weighting it down?
Do I need new adhesive?
I don't recall this gap existing the last time I had the case off about a month ago. I've been very good with the battery in that I don't charge the phone when it's warm, it's rarely used past 50%, and I don't keep on a charger all day either. But could it be that the battery is now swollen and preventing the cover from staying closed?
If I need a new battery, is there a place I could still buy a genuine Samsung battery for this? All I can find are aftermarket batteries... If not, is there a good aftermarket replacement battery?
Any advice would be welcome, thanks.
