Replace usb port charging - Nexus 7 Q&A, Help & Troubleshooting

Any one with experience can tell me where I can find or what is the exactly model of the usb charging port for the old nexus 7. I don't want to replace the all headphone jack and charge port. After I will post all the bits of soldering and replacement with pics

You can replace it with pretty much any MicroUSB-female jack, and no special parts are required.

Nexus S Micro USB

Hey,
So I've been having a lot of problems with the micro-usb port on my Nexus S. I don't know why but it seems very loose and in order for me to charge I have to position it a certain way. The USB cable easily comes out. Is there any kind of fix for this problem?
Thanks

+1 for micro USB problem
The issue you raise with the loose microUSB majorly affects my opinion of this device & Samsung as a vendor. I am on my 3rd Nexus S, the first 2 being returned for loose microUSB issues each within a few weeks of use. Now I just put up with it on my 3rd. It isn't me, else all my other phones would have the same problem. My Nexus One still performs well, so I'm switching back to it now that I have 2.3.3 running on it sweetly. I hope Samsung is not the vendor of the next Nexus phone for this very reason.

I thought I had a problen with my usb port, but it turns out the OEM usb cables are not very good, or at least not very tight. I bought a few new ones at cable wholesale and they work perfectly and fit snuggly. You can probably find some on Amazon.
The charging port on my Nexus S is fine. I bought a GPS a couple weeks ago that takes a Micro USB as well, and when I have it connected to the computer and move it, it will disconnect. If I use my Nexus S USB cable, it's a nice fit.
So.. Maybe it's the cable? I'm also wondering if you were to ever-so-slightly bend the receptacle on the phone, would that help? Not that I would recommend such a thing, but I would probably do it.
I have a few cables from my older phones they're also very loose. I'll try some more. I don't have a receipt or anything so I can't even return or claim warranty on it. Could I maybe contact Samsung about this problem?
Funny I come across this. Just noticed mine is loose and needs placing just right in order to charge.

It's the cable. I've used the samsung cable for a while now, and just recently i used a new cable and it fits as tight as the samsung cable used to be
Coming from a N900 which the USB receptor broke apart from its board, I'd say its better to have a port which is a bit loose and allows the cable to move a little than a super tight port in which every bend of cable is passed and held solely by the soldering on the board.

Mine used to be like that too. But I think its just the cable because, now I use the stock Evo cable and it fits like a charm.

If it's still warranty I guess you can still try your carrier to replace the phone. I use my old cables from my Nokia N85 and it fits perfectly and grips tightly. The stock cable doesn't even support development
I'm led to believe that the main reason (or at least one of them) that manufacturers switched to micro USB from mini USB is that the sprung part which wears out is on the devices' socket with mini USB, whereas its on the cable with micro.

Tighter USB cable

As I find the USB cable provided with the charger to be too short, I ordered a cheap 2m cable. This cable is quite tight if I want to push it into the USB port of my Nex4, so I was wondering if it is safe to use; are micro USB ports very vulnerable?

Micro USB is designed in such a way the plug wears out quicker than the socket (as it is easier/cheaper to replace the cable), so a well used plug may be loser than a newer one. Can you remember how tight the original was when you first used it?
If this new cable is tighter than the original I would be inclined to say do not use it. A cheap one is probably not made to the correct specifications and if this is the case it could damage the socket in the phone.
Buy cheap buy twice.

Phil
Thanks for your reply. It certainly is tighter than the original was at first, so I guess I won't use it for my phone then. It was only three bucks and most things I bought from China wholesales/warehouses were actually quite good concerning quality, so I don't mind it.

Extra usb ports.

Currently a work in progress but I have soldered a usb hub to the ouya and it works, I am building a custom case with acrylic plastic. I will post more progress as I go.

for anyone else who wants to give it a go these are the soldering points on the back. I am by no means a soldering pro. I was told because I am soldering on the bottom on the board the actual USB port should not be used because it can short circuit the board.. I am not 100% certain about this but for the time being I will stick to using the other 4.
current state. but all 4 ports are working.
saved for post
Jealous!! I haven't tried it yet but I was hoping to use a standard USB splitter, will that not work?
This is basically just splitting the port like a hub. It uses the same leads as the existing. There should be some extra room on the case. Perhaps get a female USB and dremel a hole. Motherboards typically come with extra USB ports that have loose ends and have screw fasteners that attach to a slot vent or case opening. FYI in case someone is thinking about doing this.
I'd say you could just cut a whole and screw in a new port. Probably look halfway professional.
Do Hubs not work? I'm pretty good with a soldering iron, might give this a go just to have my HDD and a Wireless Air mouse connected.

Hubs do work. I am looking to build it all into one housing, I have a kickstarter edition Ouya so I am doing what i can to keep the original case intact. :silly: I have attached a micro sd USB adapter to the hub and it works aswell so i hope to cram that into the case.
That's pretty awesome!! Looking to see the final case setup :thumbup:

will the G2 connect to a 3.0 USB port?

When I connect my G2 to my PC, I get the message about how it will benefit from a 3.0 USB port. As far as I can tell the USB adapter it comes with isn't a 3.0 compatible cord. I was thinking about ordering one from Amazon. What do you guys think?
*UPDATE*
Looking at the connection, a 3.0 micro cable will not connect to this phone. Wonder why I get that message. I'm guessing that this is a misnomer my PC is throwing up.
My guess is this is just a generic warning Windows 7 likes to put out for anything it thinks might be usb 3.0 compatible

No other phone or tablet I have ever used has said this, even some new ones using Snapdraon 600 chipsets. My guess is that the Snapdragon 800 in our phones does in fact feature a USB 3.0 controller for it, but we probably just have the port for a 2.0 cable which is standard.
EDIT: found this:
LG’s G2 is equipped with the Snapdragon 800, a 2.26GHz quad-core Krait CPU paired with the Adreno 330 GPU. It supports USB 3.0, up to 4K video playback and capture, and supports Quick Charge 2.0 for up to 75% faster charging times.

I am seeing the same error. Based on the color of the USB on the supplied cable, it is not a 3.0 cable. However, the device is 3.0.
I am having issues finding a USB 3 to USB micro (not micro B) cable. It would be nice to have when the time comes to start moving ROMs from the desktop to the device :laugh:

Did you see the pic I posted above? A 3.0 micro usb cable has extra pins and it's a different shape. The chipset might have 3.0 architecture, but the port is only 2.0. Maybe on a future model this might com about, but not on this phone.

Yes, I did, and the emoticons in my post were not intentional, as they are supposed to be the letter B.
The cable you posted is not what we are looking for. We need to determine if there is such a cable as a USB 3 to USB micro. This is different than the pictured cable, which is UB 3.0 to USB Micro B.
I do not have my stock cable handy, so I cannot remember if it is USB 3 at all. Is the plastic blue inside the USB side?

I think you're a little confused. You refer to "USB Micro" and "USB Micro B" as if they are different connectors. They are not. Yes, people commonly refer to it as a micro USB connector, but only because they don't know or drop the "B". The LG G2 has a USB 2.0 micro B connector on it. It does not have a USB 3.0 micro B connector on it. The cable pictured earlier in the thread is the proper USB 3.0 A to Micro B cable. Obviously, it won't fit in the LG G2, because the LG G2 does not have a USB 3.0 micro B connector. This does make it very strange that a computer would pop up a message saying that the device would work better on a USB 3.0 port when it doesn't have the necessary physical connector to support USB 3.0 but, well, sometimes technology does strange things.

What is a micro cable that's not a B? You mean a micro A?
The stock charge cable is not 3.0.
Can't you just check the transfer speeds?
The Lg G2 micro usb is not a Hdmi port, but it still supports it, through a MHL adapter. So maybe it also supports usb 3?
I am wondering if we can disassemble the phone and replace the USB board with a board that has a USB3 port soldered to it. Then of course also cut out the outer case shell to have a bigger hole. Wouldnt look as nice but it sure would be nice getting much faster speeds since both the chipset and storage system are easily capable of so much more.
Also, this is what a USB3 micro-B connector would look like on a phone:
The micro USB port is not MHL incompatible. It uses slimport like the Nexus 4.
Based on the service manual and the physical configuration of the port I believe that this phone has a USB 3.0 port, but we just don't have a cable or adapter yet to access the rear pins. Attached is a sketch I made showing what the port looks like. The service manual on page 468 supports the physical configuration of the port (3 pins on each side of central standard usb 2.0 5pins ). I am hoping the Nexus 5 will have this port and help LG push out the necessary adapter. I hope we can get some official confirmation on this at some point. I would use USB 3.0 for transferring or recording video directly to flash drive. There is also a potential for 4K recording like the Note 3. So big files would be common place while recording a 4K. 4K streaming from a G2 to a ultra HD tv has already been demonstrated at a trade show in August.
So yes, I believe a micro USB 3.0 port could be added, but by no means would it be easy, or look right. Best just hope for an adapter.

The LG G2 definitely does have a USB 3.0 connector, but unfortunately it is a proprietary non-standard connector. See my previous post. I can not find a cable with this strange new connector anywhere.

When they are saying its an A cable or B cable, they are really talking about the what the end connector will be. Think of the A connector as the standard usb connector you connect to your computer or to your wall charger. Then think of the B connector as the tiny usb connector you connect to your cell phone or tablet.
Companies sell A to A usb cables or A to B cables (which is what all cell phones use). A simple wiki search on usb will help clear things up.

You're saying it is USB3 compatible, then is this why the plug feels very tight to fit into the connection port? Sometimes it even makes a bit of a cracking sound, as if its not connecting properly, before finally fitting properly.
Looking into the connector, it does look a bit different from my Razrs connector.

That is probably for the most part because it new, but can't say for sure. My Google Nexus was getting quite loose, and I know it was tight in the beginning. It doesn't have anything to do with the proprietary USB 3.0 connector because if the plug is ever released it will be about twice as long as a standard micro USB 2.0 to reach the extra pins. I still can't figure out anything more about it.
Unfortunately from comparing various tear down of the LG G2 and the FCC teardown pictures of the Nexus 5, the Nexus 5 looks to have a standard micro USB 2.0. Definitely not as wide as a standard USB 3.0 and not as deep as the LG G2 proprietary USB 3.0 connector.

Still, there's something off about the charger on the G2. It doesn't match my Razr one, but the Razr plug fits in the G2. The other way around works, but is very, very tight.
Where did you find the breakdown of the G2? I've been looking but didn't find anything.

Am I the only one that is going crazy trying to figure out where we can find the proprietary plug/connector to fully utilize the USB 3.0 our micro-USB port?
It is also driving me nuts to see if 4K video recording will ever be possibly. I would like to record 4K directly to a USB 3.0 thumb drive.

Leeco pro 3 x720 Burned USB connector

Hi Everyone!
Unfortunatelly My x720's USB connector burned few weeks ago during fast charging.. It is burned, the connector is fuzed and I feel the burning smell, but it was already too late.
So the usb port got unusable, I can not use it for charging, and I am not able to connect to my phone!
I wanted to buy a new USB flex board but unfortunatelly there is no full (factory) version on the market!
I searched it many hours on the net, but there are only cheap ( remanufactured) version of it.
They have many missed parts, just have their solder points on the board, so these do not support OTG and fast charging.. I can not understand why can't make full version boards for a higher price, these versions are unhelpful items.
https://ibb.co/kYypx8
https://ibb.co/fnH4VT
https://ibb.co/fZM9x8
So I bought only USB C connectors and I will try to replace it on the original board!
I thing it will be a hard work, but I hope it will succeed.
If not, I have to buy a used phone for parts, and I will take out the USB board from it.
As I see, the X722 have the same flex board!
So I would buy a hard bricked x722 for parts for a good price!
Just very important to me that its USB connector be in a good condition!! Do someone would sell it??
I know unfortunatelly there are lots of users who have hard bricked dead x722...
So if you read this lines and you can help me, please write me, and I hope we can make a deal!
Thanks
Daniel
Hi, exactly the same happened to me, the USB port of my leeco was burned. I do not know if it would be because of the usb cable c stock that brings (bad quality). But you'd be surprised if I told you that, shortly after the usb port c burned down, I looked more closely at port C and there was melted black plastic on the pins of the connector. Then clean the connector with a fine needle (carefully), getting rid of the plastic, the remains are cleaned with cotton and a little isopropyl alcohol (which leaves no traces when it evaporates). After doing all the above, I was surprised when I plugged in the headphones and it worked, in the end I tried another cable type C first with the PC and it worked (it was recognized by the normal PC), then I took a chance with another charger I had at home (not the Leeco charger) and it worked ... I had no problem loading it. You could try it ..!

Yeah, you're right the original cable has very bad quality. I had already thrown it into the trash.
So I decided If I have already disassembled the phone than I will try to replace the USB C port in the next week and then I'll se what can I do.

The cables are notoriously bad, one of my x727s was destroyed by a bad cable. Fortunately, Amazon exchanged it for a new phone.
We have 4 Leeco phones in our house. I have replaced all of the USB cables with highly rated cables, that have a replacement guarantee.

Although some people recommend also switching the charger block. I don't agree with them, and think that is overkill. Its the stock cables that are garbage, not the the charging blocks.
We have four of these charging blocks and no issues with any of them. In fact, in late December, when the X727 that I returned had its usb card burned. My dad ( a retired electrical engineer) took apart one of the blocks and found it well constructed.
Next, Leeco charging blocks are approved by and meet Qualcomm standards.
https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf
If there was an issue with the charging blocks on a large scale, would they still provide this publicly available list? No, I don't think so.
Should you decide to go ahead and replace the adapter anyway, The pdf list has a section with Qualcomm approved chargers under the "Premium Power Banks" section

There are plenty of people with bricked X722's, go to the X722 unbrick thread and message those people, maybe some on will sell you their expensive paperweight for cheap.
If you live near a large city there is bound to be a shop that does repair at the component level. perhaps they could fix your damaged board or as you mentioned transfer the chips from the old board to the 3rd party board that has missing chips. The issue is that some of those chips are likely fried.

Hi
@Kener97
Thanks for the response, I would try it, maybe it would work for me as well, but it is pretty melted..Unfortunatelly I have already disassembled the phone. I did not have another cables, but now I have two good quality fast charger USB C cables, but now I already can't try it! I happy that you can use your phone after the accident. Yeah, you're right the original cable has very bad quality. I had already thrown it into the trash.
So I decided If I have already disassembled the phone than I will try to replace the USB C port in the next week and then I'll se what can I do.

Thanks for the links, but as I wrote, these USB boards unfortunatelly are not the original items just cheap versions with many missed parts! Check the images!!
You can see teir solder points on the boards. So these don't support OTG and fast charging... Only the normal charging without communications. These are not an option to solve the problem. Maybe if I would replace the missed parts from the original board if the connector replace won't be suceed.. )
I will write the result!
Anyone, any other solutions? Or anyone known where could I buy the factory version boards?
Regards,
Daniel

Hello, could you tell me if you managed to get the board working by changing the connector ? My connector also burned. also I was wondering if my earphones would work on the cheap boards that are sold on aliexpress ?

Hi!
No, only will work the slow charging and USB communication with the cheap, useless USB flex board!
But there is a solution, to get a new original x720 USB board with all functionality!
After 3 months and Iots of time what I spend on the net, I found TAOBAO chinese site, and to my surprise some seller selling the original version board there with a good price!
Use the Crome browser with built in translater!
Only one problem, TAOBAO is a chinese "domestic site", and nobody ship to abroad.
But I did not give up! And I found the final solution, that's Yoybuy! (Yoybuy.com)
Yoybuy is a forwrding site!
You can buy everything form chinese sites helped by Yoybuy, for a cheap price!! From Taobao or many chinese site and you can use it English.
Just register at Yoybuy and copy the Taobao item's link to Yoybuy and they will buy the items, what you want! You can pay by paypal as well!
I hope I could help you! My phone is back to life, and it is like a new one!
Regards
Daniel
PS. Definitely buy a new good quality USB C cable for charging ( I recommend You the Oneplus DASH cable) to stay the USB connector intact!

Hi, exactly the same happened to me, the USB port of my leeco was burned. I do not know if it would be because of the usb cable c stock that brings (bad quality). But you'd be surprised if I told you that, shortly after the usb port c burned down, I looked more closely at port C and there was melted black plastic on the pins of the connector. Then clean the connector with a fine needle (carefully), getting rid of the plastic, the remains are cleaned with cotton and a little isopropyl alcohol (which leaves no traces when it evaporates). After doing all the above, I was surprised when I plugged in the headphones and it worked, in the end I tried another cable type C first with the PC and it worked (it was recognized by the normal PC), then I took a chance with another charger I had at home (not the Leeco charger) and it worked ... I had no problem loading it. You could try it ..!

I think you make a good point about the the LeEco charger. Precisely, it is the cable that is the biggest culprit. I recently bought a x720 and had it for a week charging with an old charger and cable of my le 2. One day i couldn't find the le 2 charging cable so I decided to use the one that came with the pro 3. Just seconds after plugging the cable in I smelled burning plastic and could see smoke coming out of the usb port. I removed the cable and could immediately see that it had melted on the pins close to the edge. Funny enough, if i plug this burnt cable on my le 2 it is charging but if i plug it into the pro 3 it gets hot and starts to produce smoke. I have tried with other type c cables and the port is burning them also. Now it looks like I need to replace my usb port. I will have a closer look at it to see if it can be cleaned but I'm not hopeful. I hope i can get original parts for it because i was sold an old phone by an AliExpress seller who claims it's new. I have started a thread on it. Hopefully I can spin it out to ask anyone with information about where to get genuine parts to help restore these old phones.
