Ok.
So at some point I soft bricked my phone and I got the Phone -- ! -- Computer screen.
Managed to get it back into download mode, and then unbricked it by getting it flashed to EB01 as instructed in this thread
http://forum.xda-developers.com/showthread.php?t=1026746
So now I have EB01, which is working, however there is a new problem.
When I try to plug the phone into a computer, it is not recognized (Says the device has malfunctioned).
I have tried 3 different computers. I made sure I used the cable that came with the phone.
I brought it into the Verizon store, and they were unable to get any of their computers to recognize the phone either (we tried a few other cables there as well)
This is both in download mode and within the OS itself.
They told me to try downloading Vcast however that didn't work either.
So now I'm wondering if there is something I can do to get it to recognize it properly again.
Has anyone run into this situation before and managed to fix it?
I did twice have the phone plugged in via usb to my car, and walked out the car (was talking on the phone), and the USB yanked out, so that could have potentially damaged it (though it still charges, so I don't know)
Yanking it out could have very well done it. Only thing I would suggest is reformatting the drivers and attempting again this time leaving it plugged in and rebooting the computer. If that doesn't work, replacement time.
Do you have "usb debugging" turned on?
Did you activate the connection from the phone after connecting to computer? (mine shows a green screen with a button to activate the connection for mass storage)
beyond that... idk.
redownload the samsung drivers
based on the fact that so many PC's have been unable to connect and the info on yanking the USB charger in the car (I think we have all likely done that - though for me it has happened at work with the laptop<->network cable...) you may have damaged the plug/receptor (not sure what would be proper...).
I would do a visual inspection for kicks, though I am sure there could be damage you cannot see.
I believe that these USB connections are a minimum of 4 conductors (some devices are more proprietary and use more pins to ensure you are using an official cable so they can get you to buy more of their stuff - though some of those pins are not actually wired through the cable, but rather short to each other...). If you damaged only one, that could likely be the reason that you can get a charge but no data comm - and since it seems likely that one of the two data pins would be tx and the other rx, then I could see why teh PC would report the device had malfunctioned...
I am guessing here - logic, please don't fail me...
when phone is plugged into PC it will not show a usb connection on the phone it just charges the device the computer also does not see the phone. I have also plugged it into my macbook and nothing happens. Anyone else have this problem or any solutions?
What's your ROM?
when you put the usb in the charging port on the TB, does it feel wiggly or loose to you? It's supposed to be a solid connection. My last TB was loose in the charging port and would do the same thing
usb
try another cable, try taking out the card and putting it in the pc, the data pins might not be establishing a connection
Hey guys after trying everything possible and seeing that my buddys TB connects fine i took it to Verizon and their sending a new one in the mail hopefully that solves everything
I have the same problem, computer will charge but not recognize usb connection nor will phone recognize connection? Have had this problem across multiple roms thinking it was software problem but to no avail. Have tried multiple cables and computers? My connector appears to be in good condition visually , which probably doesn't mean much. Just wondered if anyone could think of another possibility before I lean towards hardware problem?
Had this issue before get a new cable if that doesnt work idk thats all i had to do.
I've tried 4 cables and 3 computers and 3 roms.... Guess It's a hardware problem.
had the same issue and it was hardware and my phone was replaced by Verizon.
Sometimes if you don't plug into the usb 2.0 port, things can get fishy. Usually the 2.0 port is alone opposite of the other usb ports on laptops.
Hey guys, thanks for dropping by.
I have a very wierd problem, that I just cant figure out.
It all started the other day, when I found my tablet dead after having been left on and charging during the night. The tab was dead, and I feared the worst. After having left it on what seems to me like a trickle charge for several hours, I managed to get it up and running, and the tab seems fine, it was just completely out of juice.
But my troubles are not over. Whenever I'd connect the tab to the wall charger, I'd only get the red "X" symbol in the corner, and it would say MTP Initialize, even though its plugged into the standard OEM wall charger that comes with.
When I connect the tablet to my computer using the same cable, nothing happens, and by that I mean nothing. Computer doesn't start the connection process at all, its not recognized in the device manager, nothing. Not even Odin can see the tablet when I put it in download mode, the tab keeps saying "Waitting USB Cable..."
Tried this on 2 computers, still no luck, even using a USB plug on the motherboard instead of front-usb.
Now, the tablet will "trickle charge" from both the wall charger, and the computer, but nothing else happens.
I figured it could've been the ROM, so I got the latest ICS Kanang ROM downloaded, transferred it to my tab using Bluetooth, and flashed this without hassle, but the problem still persists, only now showing a regular charge icon in the lower right section, but it is still only trickle charging as far as I can tell.
All I can figure is a defective USB cable, or even worse, defective port on the tablet itself, but I'm not sure. I've ordered a new cable from DealExtreme, that will hopefully arrive sooner rather than later.
But seeing as the tab is hardly 4-5 weeks old, I find it difficult to believe the cable is the problem.
Anyone have any ideas? I'm all out at this point, so any pointers is very appreciated. Thanks.
It could be the cable. It's the part you have used in each situation. I'd wait for the cable to arrive and test it with the tablet when you get it.
Sent from my GT-P7510 using xda premium
Hey, thanks for the reply.
Yeah, I really really hope this is the case, time will tell, DealExtreme is not the quickest dealer. I'll update when I get it.
The new cable came from DX, but I'm afraid it showed no difference on anything.
The cable is working just as the original one, so that's not the problem.
Anyone have any ideas?
I guess my main goal at the moment is flashing it back to stock and un-rooting so I can get it repaired.
You mind posting a screenshot, it's kinda hard to imagine what you see by what you read For all I know my imagination went from a red X to the corner to something like an X off battousai's face.
Then again, I'd be glad to help, provided you post screenies, would be a major help
Ah, yes, I will take screenshots of anything you want to see.
Right now im on ICS preview, and these are some snapshots WITH the cable connected.
The red "X" I'm talking about you can see on the first picture on the charging icon, this happened even when the wall charger was connected on gingerbread/overcome experience rom.
The other pictures you can see it says discharging. Now, this was taken when connected to the computer, and I guess that's normal, but it also happens exactly the same when connected to the wall charger that came with the unit.
If you want screenshots of anything else, ill get it asap!
I took a poorly image of the tab connected via USB, to my computer with Odin open, hopefully you can see what it says.
If not its just what happens, I don't get further.
By the screenshots, Is the language Swedish?
Then again thanks for providing the screenies
In your first screenshot that could be part of the theme, or was it never there previously? I don't really know if it's not charging or that's supposed to be the charging icon, because for some odd reason on ICS preview I don't see that red icon anywhere.
As for the tablet, the reason why you aren't detecting it seems as though you don't have the drivers on the PC, I don't know if you installed them or you didn't mention it because I never found it being mentioned in your reply. I know it sounds silly but the same thing happened to me when I was using the tablet, (originally my 3G series belonged to my dad who knew nothing about modding so he just gave it to me and said, "do your thing" ) He did also forget to mention that you require to have the drivers to detect it via Device Manager and MTP in general, shortly the COM port will show up aswell. Perhaps re-installing the drivers should do the trick?
Made me wonder how did you install ICS in the first place if you weren't able to have it read? But I realized you could have downloaded the zip file via the tablet, On another note, how did you install CWM in the first place? o.o
Hehe, almost! Its in Norwegian on the honeycomb picture.
The red "X" would show up whenever i was connected to the PC via USB, to indicate its not charging. It will however "trickle" charge, and take 24h to charge fully with no usage and turned off.
Yes, the red icon is not on ICS, it just says not charging in the about page, as you can see from the screenshot.
Drivers have been reinstalled two or three times on two different PC's, I don't believe this is the issue.
When I bought the unit, it was working 100%
USB was okay, I flashed and rooted the unit over to "Overcome Experience".
From there I transferred ICS preview via Bluetooth and installed that way.
Have you tried factory reset to make sure all modules are reset? Maybe the USB charge module in Overcome is conflicting.
Yes.
Factory reset 3-4 times on the two different roms. I've reset everything I could find, without success.
Perhaps it has gone faulty with the tablet's plug in port, someone had the same issue although it was his wire that was at fault, it detects the charge via USB but not enough volt's to be detected by the PC, has it been grounded? Seem's more likely :| Might have to get it checked in your local center perhaps, It's how I mentioned that any metallic object is able to relay electricity despite being broken or not, you may have a broken pin for all I know :|
Hi,
I'm having exactly the same issue with my 1 month old tab 7+. I tested it using my bosses charge cable and there is no issue so I need to go to the service centre for a warranty replacement on the cable.
Hope you sort out your issue soon!
Thanks, but I don't think I have any other choice to deliver it to Samsung Europe as a payable service to get it fixed.
Purchased on a American store, and I doubt they'll take it back with flashed software.
I'm not sure really, I'll see what I end up doing. Its not the cable, that's for sure.
Right, got a bit of a funny one here;
My girlfriend has 'adopted' my Atrix now I've moved on to the One X, but recently it's developed a rather frustrating issue in that the USB port appears to be broken. For charging, and data, even in recovery. I took it to bits to make sure there wasn't anything shorting out or dry solder joints (not that you can actually tell with the way the Atrixs Micro-USB port is designed) and it seems fine - in fact, I checked for continuity from the end of a USB cable connected to it to the pins at the back of the connector (I could reach) and all seemed okay so it's not the actual pins in the port either.
The phone always powers on when off when a USB cable is connected, but I assumed it might still be able to do this so long as +5v and GND were still connected (but then it should charge even if data doesn't work)
I'd probably never have gone to the effort of taking it apart if I'd realised that if I dump it in RSD or Fastboot mode it shows up on the computer fine.
What could be causing this? It really doesn't make any sense at all to me.
Edit: And of course, it's now sat, charging without using an external battery charger fine for the first time in days. I can't get it to do it at all now. Damn thing!
I have this exact same problem, when turned off, my phone recognizes the usb cable and starts up like normal, but when on, if I want it to connect to an ac port or computer, I have to wiggle and shake the usb connection until it charges and it can take anywhere from 20 seconds to 20 minutes. I swear I was about to throw my phone at a wall
Having a strange problem with my phone atm.
The other day I tried connecting to my PC (Win 7) to try and root my phone, only to find that my computer wouldn't recognize the phone. I've had this problem once before with my old Droid X, and that was due to me accidentally reversing the power lines on a homemade USB Host cable, which ultimately fried the USB port.
I thought maybe something similar had happened, as i've been using another homemade Host cable for charging the phone lately. This cable had never given me problems in the past, but I thought maybe something came lose and shorted. However, using that same cable, I can connect a mouse or a keyboard to my phone no problem, so I know that the USB port is still working. Because of this, i'm under the impression that the phone is maybe stuck in host mode?
I thought it might be the cable I was using, but I just bought a fresh one and it's doing the same thing: I'll hear the Win 7 device connected tone go off twice, but it won't show up with the rest of my drives, and the USB connection icon won't show up in the status bar on the phone, although the phone charges fine.
Tried factory reset, didn't help.
Also tried it on two different computers, and no dice. All the computers have the Motorola Device Manager installed.
Any ideas?
EDIT: ****! Wrong section
EDIT: Dunno if this is "progress", but after cleaning the port out with rubbing alcohol, and reinstalling the motorolla device manager, I now get a "USB device not recognized" error every time I plug the thing in... Mouse still works fine though.
Fixed it, for anybody who actually is reading this.
First, since my phone worked fine as a USB host, I tried taking one of my cables and grounding pin 4 to turn it into a Host cable.
No dice. I noticed a resistor on pin 4 though, which I thought was kinda weird for something that's supposed to be floating.
Then I read up about the whole "motorola factory cable" thing. Took the same cable, undid the Host mod, and then pulled out the resistor. Voila! Problem solved.
I guess the "Universal" in "Universal Serial Bus" was just a joke, right?
