mini micro USB is defect (battery will not charged)

Hello,
unfortunately, my micro USB connector is broken.
The battery will not charged.
Is there an instruction how can I change the mini micro USB or is there another possibility.
greets uzzoo
You can buy a seperate charger that charges the battery out of the phone, its expensive to have the micro USB port swopped out - unless you are to the job your self :
An external charger I ordered mine.
Would like to change the USB port itself, there is a tutorial somewhere as I ran to get the board?

The simple fact that you are asking for a tutorial means that you will not be able to do this job. It requires removing and replacing the actual port from the motherboard which requires some precision soldering. Send it away for repair if you wish it to be fixed.

That's a bit presumptuous! The OP might well be confident with soldering and internal electronics and by the sound of his post is (possibly! ) looking for a diagram of the board itself.
It is indeed a tricky job but the guys in the repair centre started somewhere too. For all we know the OP might even consider his HD2 expandable for such a learning experience!
Good luck OP. And you can't go wrong with an external battery charger, couple of £s from eBay. Although ive found they tend to only charge to 99% and lose the first 10% quicker than if you'd charged via the phone.

Have now found a guide how can I open the HD2.

Had thought that someone has already changed the USB beech.
Just wanted some advice.

I had this exact problem a few months ago. If you find a very skilled solderer... i.e. someone competent solder smd devices then you can re-solder the usb connector back onto the board. I would not advise doing this if you are new to soldering!
If you can't then its a new motherboard, and HTC will not pay for it under warranty because its deemed damage do to excessive use.
no the only thing you can do is a new motherboard it is'nt possible to fix it i have had the same problem cost me 200 euro.

[Q] USB port broken

im from india my usb port is broken..where can i get one?
Not sure because I just started looking for one as well. Mine broke and I'm having difficulty charging it. It seems the usb ports is loose. Any ideas would help fellas, and thanks in advance.
you could try using a horizontal Phone Cradle or Dock, and the phone will go over the usb cable and should stay there, you can get them from ebay easily enough.
Alternatively instead of charging the battery through Usb buy a secondary battery and battery charger (the cradles tend to have a battery charger built in) and when the battery needs charging, swapping the battery with the one charging. not ideal, but it is a way around.
I kept looking on the internet for replacement USB connectors and I found this. Hope it helps.
looks like I cant post the link. Go to ebay and search for "HTC Incredible S G11 Charging Connector Port Block Unit Repair Repalcement Part"
This is what it was titled. Good luck..
Just get it repaired from HTC service center ...

ya it was under warranty, i reverted it back to s-on
Guys those who have USB problem, take it seriously you should give it to the service center immediately.
It is a hardware replacement problem! For me they replaced the USB board itself.

[Q] Galaxy note charging issue - replaced charging port but still not fixed. help

Hi All,
I have read other threads and can not find answer so that is why i am creating this thread.
basic things to know...
1. Got my Galaxy Note (GN) off ebay. It came with the following major issue: "cannot be charged via laptop's usb port or wall socket"
2. GN does not have a custom rom. It is unlocked to any network. So, i am assuming it has a "stock rom". can someone tell me how to verify that?
3. I looked into various threads and ultimately decided to replace my usb charging port.
4. I should mention that before any replacement of parts whatsoever, i could see my device on windows and transfer files etc. via usb connection.
5. before and after replacement, it says its "charging" but nothing gets charged. If anything the battery level goes down. This suggests to me that there is an issue with charging circuitry somewhere? anyone can shed light on it?
6. Currently i am using an external charger to charge up my battery. Battery is fine as it gets charged up, just fine.
7. What other options do i have to find out the solution to my charging issues. Anything i can do to narrow down the issue further?
Any help will be greatly appreciated.
Regards,
Ebay is your best friend. You can change the charging usb port for less than 10 dollars. I bought mine from chinese supplier. The board cost me less than 9 dollars, shipped. It came within 2 weeks. You must open up your phone (8 tiny screws- see youtube video on how to open up n7000). The board comes out easily. You must check the revision on the usb port. Mine is 1.0. It also comes in 0.0, 0.8 and 2.0. I got the exact one with matching colors as the original part. I saw the same board in different revisions and with different colored boards. I got the same exact one, looking at the ebay picture. I was able to change my board in less than 10 minutes. problem solved.

I have already changed the usb port and the problem persists.
How much of an issue will it be if the revision number do not match up with original one?
i dont have tools infront of me so i cant check whether there is a direct match or not.
thanks for reply.

I think matching the revision is important. you must have your original part to verify which was the original revision. I have seen on threads where the revision was not matched and the part didn't help solve the problem.

Check if U607 and R619 are good, they are on the main board.
Download service manual to identify those parts and first check for bad solder joint.
I hqve the same priblem but i didnt check the part numbers gunna have a look for them now. In all honesty i thought it wouldnt matter as they may have been all the exact same

Whoah, seriously? Seems kinda like overkill. What I've heard most is having to hold the cable in 'just' the right position for it to charge, which doesn' t sound like a mainboard issue, since the charge port is connected via a ribbon block (and an antenna cable).
What's odd is that the charge port board on mine has this problem, but it is ROCK SOLID and the connector blade inside is totally clean. Pushing the plug down towards the back of the phone would, based on the physical layout of the internal USB pins, if anything, REDUCE contact pressure. It seems like this is a non-permanent problem and I SWEAR I saw an amazon post somewhere where a guy describes a simple physical mod that suddenly lets all normal charges work fine. Just can't find it...
I have a Samsung Note 2, same thing...not charging through the port, battery is good, charger is good, changed the charge port circuit and nothing...re installed the operating system, it's unlocked, rooted..works fine as long as I charge the battery externally...I have no idea what to do or which direction to go...any help...and I'll keep everyone posted as to the results of any suggestions...goo part is...I know how to get the thing apart....Blessings, As Always...
Same here - changed micro usb board and still not charging
Hi
I have the same problem. Have samd=sung galaxy note N7000 and suddenly stopped charging.
I changed the micro-usb port - it is the same version as the one inside. The mobile is still not charging! :crying:
Has anyone found a solution to this ?
even stranger
Have just noticed that the mobile charges fine in the car with the charger that originally caused the problem.
However it will charge with nothing else - neither USB port of PC not directly to wall socket.
Could the car charger have set it to charge at a higher voltage?

Maybe different battery?
or a wall battery charger?

Hi all,
Sorry to revive an ageing thread but this still seems to be an issue at large.
I have a question:
I am a little confused. After seeing a number of these charge port PCB's on Ebay, some sellers are saying only for Rev 0.8 and others say nothing at all, yet in ALL the images from numerous sellers, the PCB's have Rev 1.0 written on them including my own N7000's charge port PCB.
Please could someone enlighten me?
Many thanks!
changed usb port after charging probs
Hi there,
I am having the same damn problem. After having charging probs and a loose connection, I decided to buy a new usb port and everything should be fine again. After replacing the port i tried to charge before installing the back case part and everything worked! But after putting the phone back into the case it went back to the problem like before replacing the port. It is loose and i cant get a pc connection to work.
So after disassembling it several times and reading forum posts in several boards i found this thread which has not the answer for the problem but some suggestions what could cause the problem.
I think it is not worth it to change the Motherboard too but if someone could test it that would help I think.
In another board someone wrote he had 3 port boards bought and they were all dead on arrival. So i believe this could also be the problem what do you think? Did anyone try different replacement parts from different shops?
And is yours charging if you do not install the backplate/backcase?
where did you buy the port? and is it same revision that was in their.
I think a new cable (proper quality) fixes it
that or pc driver reinstall

Hello,
Got a similar problem. Samsung note 1 (n7000) wasn't charging the battery. Holding the mini usb down was the trick.
I bought a new charging port and replaced it. The thing....it is charging now...but giving me: Emergency calls only!
Send back that part and got it replaced.... Just installed it and again: Emergency calls only...
It does show that it has reception. It's not due to my carrier as sim in another phone is working ok. Replacing the old part solves the problem.
If anyone has an idea how to solve this problem.....PLEASE let me know.
Regards

is it same revision? connectors and touchpoints on same place?
try these:
4llerbuntu said:
Open up the phone again. and check the screws that hold down the usb port
the speaker is attached to the plastic cover on top of the usb port. it is not making contact with the right points.
try it whilst the phone is on, play a audio or video file and hold down that part with your fingers. u will see that it will work.
meaning that the screws are either loose or too tight and not properly aligned.

Nobody here can help you, get it to a repair shop and the guys there will know what to do. It's a hardware issue apparently, and a Samsung service center should be able to fix it.

Are you root and have you got a custom recovery installed?
If you are you might want to drain your battery, then charge it fully; to remove your battery stats (in CWM). That might help.
If its just your charger not charging your phone, that might indicate that youre charger isnt working, have you got another usb cable? try charging it while its connected to the pc to make sure the AC adapter itsself isnt broken.
Cheers.

Battery conector diagram

Hi, i need diagram of conector battery Motorola ex34 for direct charger. Please help me

.
Did you ever get a Diagram of the positive and negative? I got one of the 5 leg pads was burnt off and the customer needs the information off the phone. Soldering a new charge port will not get the device to charge. So thats out the window. The only option now is to get a already charged battery OR if I could find the positive and negative I could charge the battery externally and get the device to power on to retrieve information. Any help would be greatly appreciated.
