Hi Folks...
I've been using a Hero full time for just over a year, and lately have had problems charging it. Seems like the USB / EXT port has weared down to the point where the cable doesn't contact as well as it should.
Anyone else had a similar problem? Wonder if this is fixable, or time for a new phone?
If you're talking about the cable just fitting loosely, you can always put a little bit of pressure inside edge the metal end on the cable to slightly bend it outward and it will help it fit a bit more snug.
If you're talking about it actually making contact loosely on the inside, you can always get a small piece of scotch tape and put it on the outside of the large side of the metal that fits into the phone, it will help push the contacts closer to the inside of the hero's usb.
Thanks for the suggestion, ill give that a go....

Same issue here, will be trying suggested solutions.
But I see no answer to your first question: Anyone else had a similar problem?

I had this issue with 3 of my usb cables that have pulled out while using the phone in disk mode and in the car charging. I used the method to slightly bend the connector outward on the cable itself and worked fine for me. One cable is a 12" that I use on my netbook, the other 2 are 3' -- one of which I use in my wife's car for charging and the other I use on my home desktop PC.
But there are other cables that I have not had issue with --the OEM cable I use in my car and I use a different cable at work. That said, in my case, it seems the issue is more with the cables then the actual port on the phone. Either way, by using one of techniques I suggested previously and what I've mentioned above, I have no issues now. I hope that clarifies the answer.
U seem to be right..... Different cables, diffferent results.....
Bought new ones and they work beautifully
I find this incredible, my hero's usb port is still really tight after over a year of use--to the point of being hard to plug in--especially the wall charger cable (uses the full ExtUSB?) which I use every single day. What do you guys do to the poor things?
My 3.5mm port has gotten a little loose though (shear force on the connector no doubt) but bending back the copper "spring" a little has fixed that for now.
About a month or so ago I started having trouble with my transformer. When I would try to charge it, it would take several attempts before it would indicate that it was charging at all. I assumed that it was either the wall charger was going bad (as quite a few people seemed to be experiencing that) or the USB cord itself. 2 weeks ago, it stopped charging altogether, or at least I thought so initially. But after A couple of days I realized that it it was charging but there was no indication of it doing so other than the screen brightening for a split second when it was first plugged to the wall. I also start plugging it into my Pc's (A windows 7 laptop and PC and an old XP PC) I get a little pop-up saying "USB device not recognized". Ok, so at this point i'm assuming that it's a USB cord issue as there are problems with connecting to the PC and wall charger. So, just get a new charger and USB cord, right? Right. So yesterday I finally located an office depot that sells them, got home super excited with my new charger, plug the cord in and..same issues. WHAT THE FRACK!??! So now I'm thinking its either a issue with the port on my eee pad or a software/firmware issue of some sort.
A couple more details, I think the issues started around the 3.1 android update, not to say that was the cause of it. Also, I've doing a factory restore, uninstalling the asus suite and drivers and re-installing them and I've also updated to 3.2 (yesterday) still, my issues persist. Sorry for the long post and if I've posted this in the wrong spot, I'm just at wits end. help me obi wan you're my only hope...

You had a good stare at the port on the tablet with a magnifying glass and a light to make sure nothing's in there? Could be something as simple as a bit of detritus causing this problem. Might not be, but worth a proper look.
Did you install the drivers for the TF on your PC?
Also, which store is selling the charger and USB cable?

That is my next step, gonna take a look at it this afternoon under a chem lad magnifying glass. thanks.
Yes I did, uninstalled and reinstalled a couple of times. But I don't even think it should matter, as the computers should automatically see it as a storage device at least.

Couldn't notice anything after looking at it under the magnifying glass.
I have a Samsung Vibrant T959 TMobile US with 2.1-update1, Baseband T959UVJI6.
The battery is fully charged, it registers in the phone as fully charged 100%, but when I hit the power button I get a progess wheel that gets stuck, then the phone just turns off. It never gets passed that wheel, it only displays for a second then dies.
However, when I plug in the USB and hit the power button, it comes right up like it should. Then I can unplug the usb and use the phone just fine. Its almost as if I need to jump-start the phone with a power source.
I have reset the phone, even re-flashed the stock firmware using Odin. Same results. I have even swapped batteries with a buddy just to see if that was the case, but I still got the same results.
Any advice or suggestions is GREATLY appreciated. Thanks Very Much In Advance!
Anybody? Any ideas?
Well, that is new to me...
I'll preface with, I have no clue how/why that is happening. But, this is what I would do:
1 - If really opposed to rooting, I'd call T-Mo / Samsung and get a replacement.
2 - If I liked my phone and wanted to make it better, I'd root it and flash a custom ROM. It likely would take care of the issue, as it clearly is not a hardware thing (well, I say clearly).
Worst case with #2, ODIN back to stock and then do option 1.
possible solution
also it says "USB connected" even when cable is unplugged? I had similar problem.. I tried everything, flashing, changing batteries.. none of that was useful. Then I find some post on some forum that says it might be corrosion, so i scratched my USB with thin wire and everything worked fine, but also scratching USB I was doing one more thing. In my opinion, I think that it's not corrosion. I think that USB is slightly bent (middle part of it), try to bent it in other direction, possible that it's too close to edge. That solved my problem. Tell me if this helpful for you, sorry about my english

i think i can get what you are saying, cleaning the usb port on the phone right??
BUT how does this affect turning the phone on?? if usb port is rusty, it will only affect charging, not turning the power on?
I experienced this identical issue last fall -- the USB would always say it was connected, wouldn't startup unless connected to actual USB, but otherwise worked fine.
Take your phone apart and look at the solder joints on your microUSB port... mine all had cracks in them or had broken free. I re-flowed the solder while holding the port down and it resolved my issues. (put on some flux, and run a hot soldering iron across the joints, clean up... it's not very difficult. just be sure you don't short out any of the pins.) I also added additional solder to the four points that just hold the mircoUSB to the circuit board. It's been rock solid since

See if there is a TV or electronic repair place still in business in your area. Or post an ad on CL asking someone with knowledge and skill to do it. Be careful they aren't an idiot just wanting 20 bucks and happen to own a soldering iron.

you could see if Cell Phone Repair/ is near you and describe to them what you want to do.
I would go through these guys they are top notch helped me when i soft bricked my wife's phone. He even convinced me that i could fix it myself when i was ready to send it to them for a jtag.
They can replace the usb plug if thats the issue.
http://mobiletechvideos.mybigcommerce.com/samsung-vibrant/
I would test to see if my battery is bad first before i went about resoldering, it could easily be a bad battery.

No my stock battery is charging and i did buy a separate battery. same issue.
Ok so the USB port doesnt charge or show up on the computer, it was working then i had to bend the cable to certain angles for it to work then it stopped working completely is it possible to fix this?
Connection to the mainboard has broken.
Solution: Needs soldering
Probably not doable so just use a main battery charger and then use Dropbox for file transfers.
Verify that it isn't just the cable. Most of my cables have suffered from my wife walking off with the phone still attached. Had to find a really cheap source locally, fast
[EDIT]Some people may suggest using a dental tool, toothpick or strong pin to attempt a repair. If you do this, be sure to remove the battery before, just to ensure you don't short the pins and ruin your phone.
what do you mean toothpick fix how does that work?
Anybody know anywhere that can fix this? or someone or someway? whats this fixed talked about above?

Remove battery, then with a toothpick(doesn't conduct electricity), carefully clean out the usb port of the phone. you'd be amazed at the stuff that can lurk in there, fluff, potatoes etc.
did you have to bend the cable at the phone end or the middle, if middle it is more likely to be your cable that is duff.
If you get a new cable make sure it is a data cable (4 wires), not a charging one (only 2 wires)

This depends where you are in the world, in the UK there is a small oufit in South Wales that repairs the USB port for about £20 (google is your friend) but elsewhere I have no idea
As the title says I am very interested in using this tablet as a head unit replacement. I still have plenty of researching to do, but before I get too deep into it, I think there is one problem that should be addressed.
I wouldn't consider myself an audiophile, but I do like my music. So using the 3.5mm jack for audio simply will not do. I have seen a video of someone using a Turtle Beach audio adapter to get usb audio out of the N7, and then into the stereo/processing unit. This would be perfect for me, however I also need to be able to hook up an external drive for additional storage.
So my question is if it is possible to hook up the usb audio cable, and an external drive simultaneously to the N7. My idea right now is to hook up an OTG cable to the N7, then plug in a small non powered usb hub which would have both the external drive and usb audio cable hooked up to it. I am just not sure if this setup is possible, and before I purchase all the components I would like to have some confirmation that it will work like i think it will.( I will be using a rooted N7 with stickmount installed, I believe that is all I need to allow Host capabilities)
On a side note, I also plan to use the pogo pins to charge the device. I saw a video of someone using a hacked usb cable to charge the galaxy nexus with it, so i think that should work. (I just read a thread saying that the galaxy nexus can't charge through a pogo pin dock while having a OTG cable plugged...My dreams are being crushed.)
If you would like any more info about the specifics of the setup, I would be happy to share my ideas.
Sorry for the length of the post, I just want it to be clear what I am trying to do here.
Any information, or tips would be greatly appreciated.
Thank you.
I think my dreams are also crushed, I believe the pogo pins are a pin-out extension of the usb port, not a separate port, therefore using OTG would ****-block charging, which is disappointing.
You could however use one of these in your car http://www.slashgear.com/seagate-goflex-satellite-wi-fi-hard-drive-gets-android-app-01168797/ which would provide 500GB of storage accessible whilst your nexus 7 is charging, combine that and a pocketwifi device to act as a router and provide internet access it would be perfect
if you had an AC power inverter or appropriate power supply for DC to the unit (saves inverting then converting again), you could use this one http://www.ccpu.com.au/show_prod.php?class_id=disk-ext&prod_id=STAM1000200
would be very awesome, looking forward to updates.
Thanks for the info.
That is deeply saddening that you can not use both at the same time, although I guess it does make sense for the purposes of a dock. So it looks like now the only way I can still use a plugged in external hdd, usb audio, and be able to charge the device at the same time is if I can do all of that through the mini usb port in conjunction with a usb hub...but i think that is unlikely. does anyone know for sure?
And thank you for bringing up those wifi hard drives. I didn't want to use them, something about having it plugged into the device directly just makes me feel better...although now I will have to seriously consider them.
Also, if anyone has any info regarding tablet install you think may be useful, feel free to post the link. Even if it is not directly related to the N7, it could still be useful info, and maybe get some gears turning in our heads.
I just became a member so I am not allowed to post links yet :silly:
I will still keep my hopes up about using this device, though! It is my favorite 7 inch tablet by far.
What about usb powered hubs?

Can the Nexus output digital audio, charge, and read an external HDD, via powered usb hub from its one micro usb port? If it could then all my problems would be solved! Until I encounter my next problem, of course. :silly:
Sounds very interesting indeed. I look forward to seeing what can be done.

Nope. Did not work for me.
I thought about using the Nexus 7 as my car nav system as well. I stumbled across an issue where I want to mount external USB drive AND charge the tablet at the same time. I could not get the tablet to charge with a powered USB drive. I believe the tablet is going into host mode to read the USB drive, and thus disallowing any kind of power to charge itself.
Please someone prove me wrong.. I really like this tablet. It is the perfect size for the car.
Another issue I found... Using polarized sunglasses + nexus 7 (landscape mode) = completely black screen. This may or may not convince you to continue with this project. I am certainly looking at different options..
Im thinkin about this too. But not to completly replace my headunit but only to slap it on for long drives

I noticed this, too. Disappointing. My HTC EVO View works fine, though.
Very interested in this. I've actually been working on this very project. I'm near completion (sort of) actually, but I'm having a separate electrical issue currently so its been on hold for the last week or so. At this point I've run sound via the 3.5 mm jack, but if a USB solution is found, I'd be all over that. I guess I settled for the 3.5 mm jack as previously, I tended to stream Pandora and various music through the aux jack on my phone anyways. Probably more than 90% of the time actually. I may look into the Seagate GoFlex Satellite WiFi HDD for external storage since charging and USB OTG at the sime time at this point seems impossible/difficult. I have a pair of polarized oakleys that i usually wear, and havent noticed the screen blacking out yet, but I'll have to see when I get home tonight.
On charging & usb host mode at the same time..
Has anybody tried this:
1. Setup a powered USB hub plugged into the Micro OTG cable
2. hack the cable from right after the OTG cable to where it plugs into the hub, so that the voltage pins are exposed
3. solder in the voltage pins to a usb connector so you can plug in a normal charger [5V 2A]
4. check to see if you can use the USB hub and charge at the same time
I currently have a Asus transformer TF101 and the primary use is watching clips off a 500GB usb HDD. I really, really want to get a N7 and sell my TF101, but if charging & simultaneous host mode is not possible, I would be slightly hesitant to buy it, even though it is really a awesome tablet from what I hear.
so if anyone has any info on that, I would greatly appreciate it!

I know a lot of people that the 3.5 mm jack for audio. And It really does sound just fine. It is just that I am planing on investing a lot in amps/speakers, so I don't want my weakest link to be my inputs right out of the gate. Although, this tablet is making it pretty difficult to not use that jack.
I would be interested to see your project whenever you finish, or if you have information up of of the process now, that would be interesting to look at.
Thanks again everyone for all the info! I still have a shred of hope for using this tablet in my car!

I'm running 4 Polk 6" speakers that replaced the stock ones in my car (just replaced them all last year when I blew one of the stock ones), and a cadence 4 channel amp to power the speakers. Nothing top of the line, and no subwoofer or anything as of yet. Picked up the cabling from monoprice, with all of it being their "premium" selection. It all seems pretty heavy duty and solid. Only ran me around 30 bucks. I just have an 02 Mitsubishi Lancer that I'm putting this in. The dash is originally a single din so it's taken quite a bit of modification to get it to fit. More than I originally anticipated. Just a hobby project I've wanted to do for sometime and when the nexus 7 came along I jumped on it. I'll post some pics when I have a chance but at this point it looks far from professional. lol.
Also, I pulled out the Nexus 7 last night and had my polarized glasses on, no screen blackening that was mentioned previously for me. Maybe a little distortion/filter over the screen at certain angles, but still viewable.
I think this thread is great. I'd love to see/hear what other people are doing or what ideas come about from this.
Thank you, I am really glad this thread has spiked some interest, and that other people have similar ideas. I will start up my research again and come back to post any new info when I can. Gotta keep this thread going strong!

I created a thread with the few pictures I took along the way, as well as the semi-finished project. The only thing I believe I still need to do at this point is get a screen protector. (Tablet still has the plastic cover on it from when it was in the box!) Other things may come up in the future, (such as adding an OTG cable if someone figures out a way to charge simultaneously) but this is it finished for the time being.
http://forum.xda-developers.com/showthread.php?p=29824916#post29824916
Thanks for making a thread! That is very cool, I like your setup a lot. Is the tablet meant to stay in the car permanently, or do you plan on taking it out often?
Alright, I haven't had much time to find much new information. But I was just thinking if I can't have it charge from the usb port and run usb audio out at the same time, then maybe I could take off the rear cover of the N7 and cut a hole in it, where the camera was supposed to go, and route positive an negative wires directly to the battery...then I could use a hacked usb cable to charge it...? Just the thought of that is scary, but I don't plan on taking out the N7 ever, it will always stay in the car.
Just a thought, let me know what you think.
Additional info: I am going to be putting this in an 02 e46 BMW 325xi. And I will use a modified double din face plate. In my head the final setup looks beautiful, but we'll see how it turns out. As for the time frame, I have a list of parts I want to get for the car, and I want to do most everything at the same time. It will take a good 3 or 4 months before I can get everything and then installing it might take another month(assuming everything goes smoothly) I just want to get all of my preliminary research out of the way. Sorry if you guys were expecting pictures soon.
Thanks

What about the pogo pins? Aren't they for a [future] dock? I wonder if you can charge the tablet via the pogo pins and use USB OTG simultaneously? This would indeed be good news, because I will primarily use my N7 [when it arrives] for videos on a USB HDD, so it would wear out the battery to be constantly charging and discharging the battery every day.

Earlier in the thread we had thought of that, turns out you can only use one at a time, and it's a hardware limitation so no way around it.
