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.

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..

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.

thanks
I'll start from the top, I broke my phone's screen so I had it replaced by HTC. I shipped the phone (without a battery) to HTC like they wanted and got a new phone back. I installed "HD_III_BlackStone WWE" rom, and it worked fine for about 4 days or so. but eventually it wouldn't charge, I figured my battery was finally shot so I bought a new one, it worked fine for awhile but now it won't charge at all.
my computer doesn't even recognize my tilt, never says anything is connected. it does have the checkbox unchecked for computer charging, so that should be fine.
and I've tried 2 different computers with 3 different cables, as well as my car charger and 2 wall chargers =/
I've searched around but I haven't found any information regarding this, I have a feeling my car charger might've some how killed my USB port on my phone.
can anyone point me in the right direction on this? I am pretty tech savvy but I just don't know where to start troubleshooting this any deeper.
any help will be greatly appreciated, i'll be checking this frequently.

Maybe this stickied WARNING: Active Brodit Carkit thread in the Kaiser accessories forum may be of some assistance. What car charger kit have you got? Of course your replacement Kaiser should have a warranty as long as it has an official configuration. Without a working USB port you'll have difficulty restoring the original configuration as not all required steps can be done with the microSD card method - one of the risks with running custimised ROMs on devices still under warranty. If you have that particular car charger then maybe you can get some comeback from that company and a cheap Kaiser battery charging cradle will keep you going in the mean time - it just means swapping batteries to charge them. You can still use bluetooth for activesync (buying a dongle for the PC if reqd).
Thank you so much for the reply... I'll have to do the MicroSD way then, thankfully i have one finally.
but I'm not using a Brodit Carkit, the issue seems identical though so that's probably why isn't it? =/
http://forum.xda-developers.com/showthread.php?t=448467
give this a read and hope it works sounds better than above
nope, I researched as best as I could and thats not the issue either, the first reply seems correct.
I get no indication that its charging or connected through my PC or phone, that includes lights
nothing changes.
what kind of cradle will charge just the battery?

My point about that is you WONT be able to fully restore everything via the microSD card method - the SPL reversion has to be done using the USB connection.

Well whatever version you are using, if you check your port for physical damage as maxblaster linked to and thats all clear then hopefully your car kit supplier will be some help. At least the methods I suggested (battery charge cradle and bluetooth activesync) are cheap workarounds that can keep you going in the mean time. Good luck

I wanted to post a picture of one at the XDA-DEV shop (out of loyalty to this website) but cant find it anymore.
If you google Kaiser charging cradle you should find some results that have a flat recess at the back and that come with a mains adapter, the idea being you put a spare battery in the back, plug it in to the mains and it'll charge that battery. They also have a dished recess for the phone itself but you don't have to use that part to charge a battery. I have one of these devices and highly reccommend them for Kaiser users (along with a spare battery or two) as the devices are very battery hungry if you want to take advantage of all the features. PM me if you're still stuck and I can point you to a link.
thank you so much, looked around and ordered one

You're welcome. It sounds like HTC didn't repair your phone, they replaced it instead but I'd assume any replacements they provide would still be warrantied, even if only for a short period. The problem is you've customised it's ROM and while it's not in exactly the same ROM/Radio/SPL state as they supplied it to you in (or using an approved HTC 'upgrade' ROM) then they don't need to honour a warranty (restoring what you can would give you the best chance). If it is your car phone charger that was responsible for the damage then why not contact the supplier with your complaint.
Was running Alien #4, went to install CM7 and got stuck at the M. After trying to flash some more, the battery eventually drained. Left it on the charger all night, however the LCD display was on the M screen all night and would not turn off, I assume because it would not boot to a ROM.
My question is, how do you charge the battery if the damn LCD stays on when you plug it into power and you cannot turn it off? Who was the genius engineer that designed that?
Thanks.
Buy an auxiliary charger or find another Atrix to charge your battery in. Your local AT&T store could be an option for that.
external charger or bring your battery to an att store and ask them to charge it
This really belongs in general or Q&A.
I read somewhere that you can modify a usb cable by splicing the wires onto the battery to charge it, but there were no instructions. Does anyone know how to do that?
MacGyver probably does, maybe even google knows.

When you splice there is a red wire, and a black wire.... Red is for positive and Black is for negative. Make sure you keep an eye on the battery because there is no regulation of charging therefore the battery will get extremely hot. Best if you charge for 30min or 45min as that will be enough to flash a new ROM
Here's how to fix it. First, take a question that has nothing to do with Development and then ask it in the Development thread instead of oh ...General, or Question and Answer.....and THEN instead of realizing your mistake continue bantering with people about how to resolve the issue. That should do it.

^^^ How to be a moron ^^^
This question is directly related to development because this problem occurs during the flashing process you monkey. This battery issue and the lack of being able to recharge the battery in the event you cannot flash a ROM is significant and needs to be discussed. So instead of being a moron, why not contribute something.
PROBLEM EASILY SOLVED:
1. Cut a USB cable near the Micro end
2. Cut the metal "sheath" wires that hang around the other 4 wires.
3. Strip the black and Red wires to about 1 inch
4. Twist them so they are tight and not touching anything else or each other
5. Using electrical tape, tape each wire to the Marked + and - on the battery
Watch the battery for about 30-45 min and it will get a nice charge. My battery did not get hot at all, but I can certainly see how you should be careful doing this as there is no regulator on the voltage.
Lastly, its a good idea to unplug the charger from the outlet before removing the cable from the battery.
Actually it has nothing to do with development and everything to do with repair. You are cluttering this forum with your banter...

My dock has been charging my phone perfectly for weeks, the other day I came in and plopped the phone on the dock and nothing.
I checked the pogo pins (of the dock) with a multimeter, they are working. I've tried different power sources for the dock as well (wall adapter, pc, other cables).
I've checked to make sure the pins are making contact with the phone, good solid contact.
I haven't changed anything on the phone recently, any suggestions?
The phone charges fine through USB.
[ANSWERED]
since i apparently posted this on the apple forums instead of xda, all the replies were "shoulda bought apple products"
so anyone having this problem, i solved it by reinstalling a nand backup. apparently it was a software issue. hopefully this saves you from the apple fanboys.

No, I was too impatient for it and got the goosewhite dock, besides I like the looks of it better tbh. The dock is putting out power, I don't get why it's not charging. its not a complex system at all.
Get the Sony one if you don't want the same issue occurring.
Sent from my C6603 using xda premium
why would changing the dock have anything to do with the problem? when voltage is applied to the pogo pins, the phone does not charge. how would changing the dock i use make a difference in that at all?
i would understand if the pogo pins were putting out less power or no power, but they put in exactly the amount of power going into the dock, they make good solid contact, i've check continuity and its making a solid connection...
Then take the dock apart and see if anything got loose

Because the one you've bought is rubbish!
I brought this as an alternative to the Sony DK26 because I was sick of opening the flap everytime I wanted to charge my phone. It does fit the Xperia Z and looks nice enough. It also activates the dock mode and the Xperia's smart connect function. This is why I gave it 1 star. HOWEVER, it outputs at 500mA as opposed to the 1800mA delivered by the Sony dock. This means it charges your phone incredibly slowly. I had my phone on the dock charging for 11 Hours and it managed to deliver a battery charge of just 51% which is ridiculous compared to the Sony charger which delivers a 100% charge in 2 hours.

I do not get why would anyone go for something cheaper and unreliable. Its like those iPhone users buying cheap non original cables to charge their iPhones, ended up causing the phone to blow up or messed up and blames it on Apple.
and yes you are the owner of the phone and you have the right to buy whatever 3rd party equipment for your phone, but dont expect it to work 100%.
Doesnt make sense if you ask me sir.
It is really hard to determine the main cause of this matter. It could be your phone: hardware or software (i doubt it is this one), or the 3rd party dock.
You tell me which one to throw and buy a new one.
Already told you why I bought it. There's nothing but stupidity in that review as docks do not put out power, they transfer it, the power supply puts out power. As for the amperage, it puts out what you put in. it will do [email protected] if you are stupid enough to put that through it... Assuming the wires don't burn. if you are going to base your assumptions on a review, at least choose one from someone knowledgeable. also, my dock never took 11 hours to charge, not that i ever bothered timing it but it sure as hell wasnt more than 4 hours (and thats giving an a good bit of a safety margin), i'd guess 2 hours 0-100 if i had to.
What I'm telling you is that the phone is not accepting the charge, not that the dock is messed up but the phone. And I wanted to know if anyone had similar issues or suggestions.
I'm glad you have insight on the matter and an opinion, however you are not trying to answer the question. I've already informed you the dock is intact and making a connection. I've checked the voltage of the xperia official charger at the cable at its end: 4v dc, the dock when hooked to that charger is 4v dc tested at the pins. I can put a larger amount through it, and any number of amps. A pogo dock is a very simple device, official or otherwise, the difference is mainly in price and design. The diy thread is a perfect example of that.

From me to you.
Hey guys.
I bought one of those NewWisdom stickers and it worked like a charm..... for a week. Then it would sit on the charger, show charging for a second, and then it would "disconnect". I am using multiple Tylt's and other chargers that I know work, but this error happened.
I read that the little stickers can be crappy and go bad, so I asked for a warranty replacement. I got a new one, installed it, and bam, same issue right away.
Is it more likely that I got 2 faulty charging stickers? Or that something is wrong on the inside of the phone?
I know you've posted on the threads re: the sticker.
Re: breakdown of the charging, I think the most relevant thread re: this is here:

Though lots of reports here too:
http://forum.xda-developers.com/g4/general/wireless-charging-meltdowns-t3163156
Are you saying that right after the new sticker install, it never worked? Or it worked, then stopped?
It's becoming a widespread issue. Not everyone, but A LOT of folks.
My personal opinion, based on my observations on 2 phones using an OEM charging back, with a new sticker as a backup checker, is it is a hardware issue within the phone. Or perhaps some software issue tied into the hardware.

Thanks for the links. The Additional information helps.
I posted to see what sticker was best and if anyone had one die on them. Seems that this is common enough. I hadn't posted this exact question before.
The new one i bought never worked. I know the pins are lined up and I even padded the back of them a little. My QI pads all show a green light, then a red light. Makes me think the sticker works just fine, but the inside of the phone is FUBARed.
I want to like this phone, i really do.

Hahah, me too! The camera, if you don't get one with a pink tinge overlay, is fantastic! The iffy touchscreen issues are fixed with the 10N update!
The fact the wireless charging capability keeps breaking down as a hardware issue is ridiculous though.
I may post a poll to see if anyone has managed to keep their charging ability >1 month. Maybe when more time passes, as the phone is still quite new.
Just to let people know... I got a replacement today and the back that didn't work on my current phone works perfectly on the new one. For some reason... This issue is tied to the phone and not the stickers coming out.

Yup there's definitely a faulty part in these phones.
Let us know how long the wireless charging lasts on this one.
Just a note, my wireless charging also stopped. It was a sticker I put on the original back. Just figured i'd screw with it later and that it probably wasn't making good contact so I picked up a regular wireless circle case to use in the meantime and it's also not charging. Likely something in the phone but I have no idea where to start. Oh well, that month of wireless charging was nice again. (and yes, I've tried different chargers that I know work, etc. Hah!)
Going strong for 4 weeks and still charging(with three different QI chargers and two different stickers). Possible cheap quality chargers are blowing out the hardware?
