mOrE URGENT HELP WATED - Have I fried my Nexus One?

Hi guys,
I stupidly plugged my Nexus One USB cable into a higher voltage charger in my car, about 8v-10v I think, and I could immediately smell burning. I unplugged it straight away and the phone died. The result was;
1. I could no longer charge it off the wall charger or computer USB charger, just got zero response, no led's etc.. seemed as though the phone was totally gone.
2. Then I took the battery out and charged it in my external battery charger. When I put the battery back in the phone it turned on and worked perfectly!!! although the battery didn't seem to last as long.
3. When it was powered on an working, it wouldn't pick up the USB connection to my PC. Did nothing.
So.... it seems as though the USB port is obviously not working. Would this be the extent of the damage or would it be something more serious in the phone?
Would the official Google dock allow me to charge the phone and connect it to my computer given that it uses the 3 pin method and not the USB?
Any help would be greatly appreciated.
Cheers,
Morgan

Ahhhh the smell of a resistor going. And within a circuit when one major component goes it will drag some others with it. Which could explain short battery life. Back up your stuff. And look into your options to replace device. Unless you have extencesive knowlege on micro surface mounted printed circuit board components and measureing values.
good day.

I don't have any knowledge of circuit boards so is there any other options to repairing this device? It is basically brand new!
Is there any chance that a dock would allow me to charge it?
If not, can I replace the main board? I disassembled it yesterday and know how to change it out.

Just guessing, but no. The cooked components for the charging circuit would also be in parallel to the dock port.

Blaze charging question

Hello everyone,
I purchased a used Blaze a few weeks ago and i can not get it to charge passed 60% even after 1 whole day plugged into the wall and using different chargers. The phone was rooted and had custom mod with android 4.1.2. The battery graph seems to plateau every 5-10% then last night it went from 67% straight down to 45% not a gradual decline and it was plugged in. My question is should I even bother with a battery, reload stock rom, or replace usb port? Is it even worth it? I purchased the phone with intentions of putting it on straighttalk so i like the fact that i do not have a contract but then again i have to deal with hardware malfunction myself.
Thanks in advance!!!

I use to have this problem until I replaced my USB port.

Can I take the USB port from let's say an lg p509 and put it on my blaze?I don't see why it would be a problem

the usb port on the blaze is soldered to the board and would be extremely difficult to do unless you have good experience.
I am not sure if that would work, I think it is $40 for a professional to work on it.
Take into account, it may not be the usb but maybe the cable.

take into consideration that the port itself my not be bad, but the USB board itself, in which taking a board from another phone would not work.

I agree. always try for the cheaper option first USB cables are much cheaper
Apart from that, IF the problem was the USB port and not the board, and IF you had a micro soldering iron, and IF you had the soldering skills to remove the old port and re-solder the newer port without crossing circuits and frying your phone, it MIGHT work.
its better just to buy an OEM replacement USB board and swap them. It will save you more headache and have a higher chance of success.

On Charge Draining Like No Tomorow

I Have A Samsung Galaxy Note 10.1 I Got It About 8 Months Ago I've Used The Samsung Official Charging "Cable" For Most Of That 8 Months but about 2 months ago the cable became loose at the Samsung cable to tablet end exposing the wires so I was careful with it and put it away and used my friends official cable then he needed it back so I went off and brought a generic cheep cable for $3.50 So all was good there but slowly I've noticed my battery going crazy like taking longer to charge "2 Days to full" and things like it discharging by 2% when I am on Google while its on charge and when its off charge playing 1 game uses almost all the battery.
so being the awesome soldier that I am I made myself a 5cm cable hoping that the long cable I was using had something to do with it but still I had the problems listed above so I did some Googleing and maybe a 2.5A charger would be helpful But its not recommended. also I sent a email to Samsung and being the "SUPER HELPFULL COMPANY THAT THEY ARE" has not responded to my emails in the past week's Also I Spoke To A live chat person thing and Being "Soo Helpful! " Said that its a hardware fault and I need to take it into a Samsung repair place and fork out $100+ Bucks to get it fixed "HELL NO AnT No BoDy GoT TiMe FoR ThAt" so I didn't go to Samsung to get it repaired so I want to know if any of you guys out there have any idea to fix this problem im having because its so hard to do anything.
Just Checking my emails while its on charge uses %4, On Google for like 5 mins Uses 2%, Playing A Game For 30Mins Uses Well Almost Flattens It, And Watching Some YouTube Takes It Down To 0% And Then Shuts Down( I Watch Lost Of Videos) All This While Its On Charge
At The Moment How Im Copeing Is I Carry Arrount An Inverter And A 12V Battery To Keep It Charging

The SGN 10.1 charging cable is a specially designed cable to deliver 2.1A 5V to the device.
Most "cheap" cable on the market can only deliver 0.5A - 1A 5V when used to charge SGN 10.1
You should find the correct cable specifically built for SGN 10.1

Thanks but how can a cable make all the difference i managed to charge off my old one its just got exposed wires and it still drains when i use it

Are you certain that the battery is actually draining that fast and not simply misreporting it in the UI?
I had a similar problem where the battery didn't seem to last but I eventually noticed that a reboot would completely change the amount of charge remaining, sometimes by as much as 20%. I cleared the battery stats and is been fine since.

Well actually when-ever I turn it off it doesent charge much and if I restart it the battery stays the same but over the last few days ive noticed something weird when its on chatge and I play a game it drops about 20-30% but when its not on charge and on battery it drops by about 5-6% could the charger be draining it? also I have a new new cable its generic (IM NOT PAYING $60 FOR A CHARGER CABLE) and there is no difference still does the weird charging thing also I tried the old cable and still does the same thing the olny thing wrong with the old cable is that the wires where exposed so I dident want to use it just incase it broke

If you don't want an OEM cable and charger you can buy a crap chinese one. But as you and many others have discovered - they suck. This is one of the biggest complaints I have always heard about Samsung.
The solution, and the only on that I have found that works 100% of the time is to buy a replacement from Samsung. Period. Nothing else works like the OEM parts because they aren't OEM parts.

The wiring on the OEM cable is somehow different than most cheap cable.
I'm experimenting by buying a 3M long "cheap" N8000 cable on eBay, may be it can help (delivery time is VERY long )

What ROM are you using?
Stock or Custom?
Rooted or not?
If you are Rooted (Stock or Custom) you can use Battery Calibration app to erase batterystats.bin to calibrate your battery percentage which are needed if you change ROM.

$60 just for a cable? Really? I live in the UK and I bought a whole new charger (official Samsung one, too, including a cable) for about £12 on amazon. Just go to Amazon and replace the charger, it sounds like it'll be cheaper than just the cable (probably 15-20 USD or maybe 30-35 AUD, I'm not sure what the rate is and where you live ) and if it is a charger related issue that'll be fixed too.
Just so you know, I bought the 'travel charger' (the white one) and it works perfectly. Supplies the same current and voltage, and it's a smaller unit, and cheaper! I'd just look into getting one of those.

A100not recognizing battery??

I have an A100 that was given to me by a friend. It works fine when plugged into the charger. It says "battery status unknown" in system settings and when I unplug it it dies of course. My friend says that their dog chewed the charger cord so they put it away in the closet for about a hear and recently bought a new charger. This issue has been a problem ever sense. I'm thinking that the charging circuit may have been fried. I'm not sure however if the charging circuit is built into the battery or the main board. I can order a battery for around $50 but I don't want to spend it if it isn't going to fix the issue. I tried to OTA to ICS but it won't start the install without a battery charge at least 30%. I plan on breaking out my trusty multi-meter later today and testing some voltages at teatbpoints in the mainboard. Any other ideas? Has anyone else experienced this issue??

My A100 does the same thing. It started after I replaced the LCD. I replaced the battery with one from eBay, but it made no difference. The charge may have run down while I was waiting on the LCD, but I don't know for. As far the eBay battery, who knows about that. It could be charging circuit, since two batteries did the same thing. But, now that I think about it, the original showed 3% charge for a while which enabled me to move to another spot and plug it back in.

Mine did that a while ago, when still under warranty. Sent to Acer, they fixed that charging circuit. Apparently a common problem. I suspect a regulator chip, but it's a guess.

You could honestly just charge the battery sepretly, and I bet it'd work. You could even, if you're talented enough, strap a bigger battery to it and be able to use it for days.

With my A100 not even recognizing that the battery is plugged in, I doubt charging it separately would make a difference. I just want it to "think" the battery is there and charged to at least 30% so I can apply a few OTA updates and acquire root. I don't mind having to use it while on AC power only. I have a Galaxy Tab 2 that I can carry around.

[Q] sch i535 micro usb connection charging problem

Hi,
I have had my phone since August 2012. Starting the other day my micro usb port on my S3 is starting to get really picky as to how it must be positioned to charge. I have tried atleast 4 different cables, all doing the same thing. I know its just a matter of time before it stops charging all together...
My question is
A)Is the micro USB replaceable (I have no soldering experience)
B)Should I replace the whole motherboard
C)Should I look for a new phone (I can use my brothers upgrade.... but only as last resort)
What are your thoughts?
Thanks!

You under warenty?

I see videos for replacing just the usb part ON the motherboard, some people solder (like I said, I never soldered before)
AND there are some 'unprofessional' looking videos where people use a heat gun (which I have) to just replace it.
As for the motherboard replacement, there are good complete disassemblies of the S3, and some boards can be found on ebay
but for $130...

Well you should be careful charging your phone next time perhaps when you get a new device don't let the charger yank down on the port itself
Sent from my SCH-I535 using Tapatalk

you could always invest in wireless charging! Then you wouldnt have to deal with it! Could be a good alternative!
I found this:
http://www.amazon.com/SainSonic-Standard-Wireless-Charger-Receiver/dp/B00C3DKSRM?tag=notebookscom-20
and then you can just buy a wireless charger and boom no more worrying about the microusb port!

You could also buy a spare battery and one if those wall charger that you put the battery in (like that come with the zero lemon 2300 slims). You essentially charge the battery outside the phone, then just pop the charged battery in (no touching charging port on your phone). I think they're like 20 something bucks on Amazon and come with that wall charger thing.

I actually already had a external battery charger for my phone! I completely forgot I had it hahah!! I'll use this method until I can get an upgrade in August. Thanks everyone for your help
