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...

I have an Eris that I need to return.
I've tried numerous USB cables. I've tried on two windows machines (with drivers installed) and a linux machine. I have a replacement Eris that connects with no problem, on the same machines, with the same cables. I've tried connecting once it is booted up, I've tried enabling USB-MS in recovery. And nothing. The phone will charge, but that is it. It is in no way recognized as being connected to any computer. Nor does the phone itself recognize that it is connected to a computer. The only conclusion that I can come to is that there is damage to the physical USB connection on the phone or internal to the phone that is preventing it from connecting.
BTW... the phone is being warrantied due to an issue with the 3.5mm headphone/microphone jack. The phone believes that there is a microphone connected at all times. I doubt these two are connected.
The phone is rooted, and I have a custom boot splash. I can easily return to an unrooted state via the SD card, but as far as the boot splash, I can only find methods that required an USB connection.
Are there any alternative ways to change the boot splash screen that do not required a USB connection?
Is there something I'm overlooking as to why my USB will not connect?
Thanks.
Well, I think I confirmed my suspession on the faulty USB connection. After about an hour of wiggling, connecting, disconnecting, etc, I found that magic spot that allowed it to connect. While connected, I was able to use fastboot to push the new splash. Time to flash a stock rom and put this thing back in the box.
Glad you got it working long enough. FYI the only time I had to exchange an Eris, I had an image of my business card as my splash screen, and I didn't have time to get it off the Eris. They never said anything about it. Some other people have reported returning fully rooted Erises with custom ROMs and not having an issue, either.
If it was my choice, however, I would be cautious like you are being, and put everything back as stock as possible.
My SGS2 keeps disconnecting and reconnecting the usb with my computer. This is hapenning for quite a long time now.
I keep hearing the windows connect/disconnect usb sound when my phone is plugged in, making it unable to recognize the device.
Today, it finally didn't had this problem for a while, so I took my chance to get back to stock ROM (because I need to send my phone to Samsung for camera problems). So I flashed stock ROM with ODIN, but I encoutered a problem: it didn't get further than the boot animation.
When I tried to reflash, ODIN didn't recognize my phone anymore, just like before. When I plug in my SGS2 to my computer while on download mode, it just keeps reconecting the USB, so the device can't be installed.
Tried a different computer. It kept being connected, but that comp sucks and it couldn't recognize my phone at all. My own computer also has problems recognizing the SGS2, but also has the problem that it can't stay connected.
Things to know:
- Other usb devices do stay connected, it's just for my sgs2
- I've tried different USB hubs etc., reinstalling Kies, uninstalling drivers.
- It does keep charging the phone, even when the computer makes the disconnect sound. That makes it even weirder!
Basically I'm seriously out of clues how to revive my phone
I don't want to send it to Samsung, scared of losing warranty.
You guys are my last hope!
to start the ball rolling, YOU SHOULDNT BE connecting sgs2 to a HUB, thats probably the fault, second, have you tried a different usb lead or a different computer with the same lead to either verify if its the phone or lead at fault??
No one on here can answer your question because it sounds like a hardware issue, wire or hub or charger port, but it is an elimination process and only you can do that.
If you try everything and still get no joy, restore your pc to an earlier point, uninstall the samsung drivers and re-install them etc etc.
I very much doubt its a software problem tho, looking at what you tried already, lots of people use hubs, if youre flashing roms and your connected to a hub then ya play a dangerous game and risk soft bricking your phone, most of the time odin wont recognise your phone through a hub, same if ya usb lead is too long, itll charge but no data. always connect it directly to the pc usb 2 port.

Ow, I think I used the wrong word. I meant to say port instead of hub.. Translation fail there. So that's not the problem, I've put the cable directly into the USB port.
I think you are right about the hardware problem. I'm just not sure where the problem is. I only have one cable, so I can't test that atm. But like I said, the connection problem does NOT occur on another computer. It keeps the device connected (as an unknown device though).
So it's weird: it looks like a SGS2 hardware problem, but on the same time it has a different problem on a different computer. It's really confusing...
Thanks for the quick reply by the way

Android Sync manager Wifi is the answer you're looking for ^^
no more plugging in this... mounting that...
NB, has a pc side component

Then please explain me how I could ever do that when there is no working ROM on my phone. I'm stuck on the 'restore with Kies' screen, like I told in my post (yes, still). And how it will ever work with ODIN? It won't...
Now not any computer is connecting with my sgs2. It just doesn't show anything (not even unknown device). I'm going to try to buy a new cable. Is it needed to buy a Samsung cable? Because it's harder to find than just a regular usb to micro usb cable (and more expensive ). This is my last hope. When it's not working, I need to send it to Samsung.

You need to replace your usb board within your phone. New part can be found on ebay for around $10. It's a really simple task replacing it. No soldering or anything.
It's been well documented on these boards.

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?
On my TF201, about an hour ago, my USB connection to it just dropped. No loose connections, brand-new cable. I had thought it was just a bug in my USB drivers, so I quickly unplugged/replugged the device. No connection. I rebooted both devices at least 2 times, and still no luck. I figured that I might be able to determine what's wrong by connecting the cord to the wall plug. It charged just fine. after that, I assumed that it was the computer's USB port, so I plugged my phone into the same port. Was able to get adb connected to my phone, no issues. My question is, How could I determine what the issue is, without RMA'ing it or resetting it?
(Also wondering if me connecting a flash drive to the keyboard dock with it showing up for a split second then going away is any indication of anything, I'm just going to assume the worst and say the USB is shot)
I have the same problem bro. I don't know what to do I am be very pissed. I read somewhere on xda a guy had a problem with his epic and took a qtip with alcohol and cleaned the contacts and it worked. I will try this tomorrow and get back to you. I have tried other pc but nothing works and I hate not having root and I add-on considering selling my prime just because of this
Kinda have it working, in the sense that the USB cable, when connected, will make the device show up in Device Manager as an "Unknown Device", but much past that, I'm not sure. I don't have the device near me right now, I will on Monday, but once I can, I will try the alcohol trick, it worked for my phone, and the keyboard dock. (BTW, I did blow into the USB port, and now the devices attached show up for 45 minutes - 1 hour before they disappear, and also, when connecting an SD card into the dock, it shows up, but on the case that the micro SD is not connected in the device (Dunno if it does this normally or what)
I've tried everything I can find on the web to repair this sm-n920a. Any time I plug it into a computer it comes up with a usb error.
I've even replaced the charging port, with no luck. It charges fine, doesn't appear to be any damage, tried 5 different usb cords that are working fine with other phones.
The ultimate goal for me is to update it to nougat, but the ota won't push on it from at&t, and obviously I can't force it to update plugged into the computer.
This even happens in download mode.
This happened to a lot of these phones, the ultimate real fix it seems to be replacing the mobo, but would like to know if anyone has any real fix, or a way to work around it to install nougat. I've tried a dozen things to get it to try to push nougat too with no luck.
Since these phones dont even have an sd card I can't even load files onto it unless maybe by bluetooth?
I wonder if I moved nougat over to it by bluetooth could I then get it to install somehow?
I just verified it's definitely something wrong with the phone cause I can insert a usb dongle that I have and a usb drive which comes up fine on my note 4, but doesn't appear on the note 5...although the light on the usb drive turns on, but it just doesnt see it...so there must be something wrong with the drivers on the phone, or something on the phone end...any help would be appreciated.
usb host check shows usb host not enabled on the phone. Can only "fix" it it appears with root, can't root without usb access.....daaaammmnnn
