I managed to fry my kaisers circuits by plugging a 4 AMP car charger into the USB power port.
It only took one second, i smelled the smoke and instantly unplugged the cable, but it was too late.
Surprisingly the device was still powered and functioning, so i didn't freak out. The battery was already dead. after around 30 seconds it died again, i walked back home and tried charging it with mains adapter with no luck.
Next morning, i took my handset to a local electronics repair shop to check it, and i told them the story. they called me back and said the motherboard needs to be replaced. and it would cost me around $470. (and its not covered by manufacturers warranty. ouch!!)
After hours of cursing and smashing my head into the steering wheel, i thought i'll pick it back and try something my self.
the part where the device stayed on even after the smoke came out led me to believe that the board is still fine. and that only the charging port got fried.
the problem is, I don't have a desk charger to charge my battery and test my theory, a disassembly guide would also be very helpful.
if the main mother board was really fried, is there any place that i can buy it from? i did some goggling around with no luck.Anything cheaper than what these guys are asking for would be great, i have a feeling they are trying to rip me off.
If any of you guys can help me out, id be grateful.

I have a brand new AT&T Tilt ( kaiserII HTC8925) for sale i can sell to you for $375.00 New In the box never been used. PM me if interested.
Sorry I can't help in this matter, but I thought i would post this here rather than start a whole new thread.
I have heard lots of horror stories of in-car chargers frying kaisers. Has anyone got an in-car charger that works?

Order one that is made for the Kaiser...a lot of people are trying to use old chargers just cause the tip is the same.
I got my stuff from PocketSolutions.com
Car chargers that work for the 8525 should work fine for the 8925. It just can't do that "boost" charging feature the Tilt supposedly has.

That one won't damage the Kaiser, but it has only half the mA of the proper one. This can sometimes cause problems if the charge level of the battery is very low. For charging from time to time and when battery isn't near empty you will be ok.
Mike
well a quick tip would probably be checking the fuze on your charger, anything below an amp wouldnt do much damage. -.-;
4 amps fried my tilts motherboard, so watch out guys
still looking for a service manual, now that my phone is dead, i want to dissect it,
I'm using a cheapy chinese one made for an Imate Jam if that helps.

the part of the board responsible for charging is probably what went up in smoke - you probably smelt (smelled?) resistors/capacitors overheating/melting - they said a total mobo replace as that circuitry is probably all on the same board - sure you might be able to replace it yourself but i dunno - might be a bit of a mega mission what with all these micro components around on these sorts of device

Yep, these devices now have multilayer boards that make it virtually impossible to do a bit of home soldering/component replacement on.
Bring back the days of my youth when we had valves (tubes in US I believe), they were nice - and kept your hands warm as you soldered away in a freezing garage

Cracked Open
I opened up the case and unscrewed my way to the burnt part of the board.
thanks to mike and the manual he posted on some other fourm

Okay now i can at least see where the damage is.
Still stubborn that i am, I did not believe that this IC killed the entire mobo, so i invested in a desk charger for the battery and charged it up fully.
I just tested it now and to my surprise it WORKED!!
http://img211.imageshack.us/img211/5070/ks5vj6.jpg
Of course, my joy ride did not last for long as the device started heating up. I switched it back off once i felt the abnormal amount of heat generated.
I tried it again after it cooled down. This time I kept it for around three mins, and again it heated up, at the end of, it just shut it self off. (still heating up).
After that scary little experiment i learned few things:
1- The device motherboard is alive, there is no need to replace the entire board.
2- The burnt IC is probably meant to control the usb port and the power, therefore my usb port is useless at this stage.
3- charging the battery externally wont help much without resolving the heat issue.
I tried to look up diagrams for the devices board and the only thing i could found is this:
http://www.cdmatech.com/download_library/pdf/diagram_msm7200_cs.pdf
which is useless.
Any help would be much appreciated..
cheers
Can anyone help me with this?

the chip burnt shown in the picture above needs to be replaced on my tytnz mobo.
can anyone give me more details about it or where can i find a replacement, all i could read on it is the (QRA) part, if anyone has a tytn II could you have a closer look, grab me a serial number maybe.

Recently a bad charger accident fried my nexus one. On investigation it was found that the mid chassis has been damaged and if i get a replacement for the same the phone should work fine. Since am in India, this phone is not covered under warranty nor are the part available. Can somebody help me by pointing me to site wherein i can buy the spares for the phone. I found this site in China but they are not selling it as of now.

The part shown is the one that has been damaged.
Great find thanks

I stopped using my home charger because a few days ago, I'd plug it in, it would show it was charging but I'd wake up and it would be almost dead. Next night, same thing. I plugged it in one day, watched it, and it was LOSING power pretty quickly.
I think my charger has a short as well.
I think im having a problem with my charger as well, If i use the A/C charger when I wake up the phone is extremely hot so I play it safe and use usb and a blackberry charger
Last july, I took my Milestone on a hike and fell on it, breaking the glass. I sent it for repairs and got it back after a nice 120$ bill.
When it came back, the charging plug was loose, but still worked well. Considering this was my only phone (I'm in an appartement without landline), only MP3, acted as my agenda, adress book and GPS, and that I knew that sending it back in would take another 4-6 weeks, I decided to keep it anyways. It was still charging, right?
Well it progressively got looser, and now it won't charge unless it's in the dock, at a certain angle forward, and the 1-year guarantee ended 3 weeks ago... So it's useless as a GPS, and I have to mess with it for a minute everytime I plug it in to make sure it's at the right angle...
Besides sending it back to Motorola, waiting 6 weeks and paying 120$ (again), does anyone else have found a solution to this issue? Is this a part that can be bought myself and replaced by someone skilled?
Thanks!
PS: Here in Quebec, the Consumer Protection Law states that a product should be covered for a reasonable time period... I'm thinking of putting pressure on them by saying that a reasonable time period would be the length of the contract with the carrier, and so that they should repair/replace it under guarantee. Opinions on that?
Buy a battery charger off eBay, they are cheap

I'm talking about the charging port. The microUSB on the phone itself.
He knows, thats still what I would do. You also need a microUSB reader or use wifi to transfer stuff.
If its loose, then it may be just a torn wire, not my forte in small electronics.
If its 120, buy another one. You can get one off ebay cheap, or get one for parts.
Well, the phone just completely died, and won't power on at all-no matter what's the battery I used. I guess that won't be necessary now, lol.
Well, you should take it to repair, maybe you battery has died and some one need to weak-up it.
IMHO is better then buying another one.
I would do what the second poster was sayin and by a battery charger put it to good use again.
I reciveved my phone yesterday and after playing with it for a few hours I charged it last night and noticed it became hot to the touch in a few minutes of being plugged in. Like burn your hand hot and there was a bit of a hot plastic smell coming off it. I unplugged it let it rest. Today I have no usb access to it. No adb, no fastboot. Lsusb shows no devices etc.

Xplodwild tweeted out the other day about issue with USB charging similar to this. Does the same happen when AC charging?
Is this problem similar to this guy?
Watch out for overheating!
seems to be a similar issue - it was very hot on the back side just below the camera especially I'm just afraid it got too hot and something was damaged.
This explains why google was pushing their bumpers instead of a full case I can't imagine a case would be good for this things thermal characteristics.
This happened while charging via ac when charging via usb it just seems to hold steady at whatever level the battery was.
Just out of interest, what surface did you leave it on all night?

I left it on a wooden desk for 5 to 10 minutes it didn't take long
It is no longer charging. I can't get it back to stock to rma I'm not happy :crying:
Woah, all other nexus 4 problems aside, this one is quite serious.
Just imagine what would have happened if you'd have left it on a easily flammable surface and wouldn't have noticed the heat. Worst case scenario might have been a fire or something like that.
If this really is a common problem (I've already seen at least two people reporting similar issues), we might see a big recall campaign quite soon.
I guess you don't really want the LiPo battery in your phone burst like this

Maybe Google should start to sell these bags instead of the bumper
Where you using the provided USB-AC adapter?
I know that my friends GS2 and GS3 got really hot when using my playbook wall charger (rated at 5v ~1.8A) :S
Heard of similiar issues with nexus 7, but the one I'm aware of is still charging.
I haven't experienced this issue yet?
I contacted google play they were quite happy to send me a replacement. Aparently they held back stock in case of a need for returns. HOWEVER they tried to charge an authorization hold on my account in the ammount of $350 I DONT HAVE ANY DAMNED MONEY I JUST SPENT IT on their ****! The only other option they said was to return it for a refund and wait a large number of weeks for orders to open up again or send it directly to LG for the same treatment ?!? I'm PISSED. The guy said that this was not the first case he'd heard of like mine didn't even ask any questions except for the serial number - I'd expect that there are going to be quite a few issues like this.

Yeah, sounds like my problem. Was your microUSB port also loose/creaky like mine? I got Google to RMA me a new one. It's a shame, I love this phone and this one has no give on the screen whatsoever and no rattle. The port though and the screen flicker are another story...

I don't have screen flicker yet and the port isn't lose I'm thinking somebody cut some corners on the voltage regulation

Damn, I guess this is sorta good news for all the folks (myself included) whose banks dropped the authorization, haven't had Google recharge us, and have the phone in hand.
I have an HTC One M7 that I have been happy with for nearly 2 years. Yesterday I plugged it in to the charger in the car that I have used hundreds of times and there was a little wisp of smoke and now the USB port doesn't seem to work. I can't charge it and it isn't recognised by the computer. Everything about the phone works ok, but I can't get any power into it!
I have it rooted and have ViperOne running and the problem is I don't think there is enough battery to get it back to stock to send back for warranty!
Can anyone suggest any method of charging? Long shot I know...

I had the same problem with the smoke, and I left it to sit for about a year. Usually, they don't turn on the phone to check it's "stockness" and even if they did, if you keep turning on your phone enough until it is absolutely dead, they can't recover it without replacing the charge port. I decided to replace the charge port, and let me tell you, there IS a glue around the sides that you have to heat up to take off. I would recommend buying a charge port w/ flex cable and taking it to an electronic repair shop and hopefully the guy understand what to do. I did it myself but pretty much destroyed the phone, so if you can make sure it is completely dead and send it in they cannot check if it is rooted or not.

Cheers, I've taken your advice, drained the battery completely and sent it off for warranty. I did read something that said warranty shouldn't be affected unless the custom software is the cause of the fault so will cross my fingers...
The warranty is voided even if it is not the cause.
