Hey guys,
Recently I have not been able to connect my phone to PC. I've tried hard resetting, as well as loading the phone in "upgrade" mode (power+camera+reset) and in both cases the PC did not recognise the phone...
it says "unknown device found" when in "upgrade" mode and says nothing while connected while in windows.
Any ideas guys? I have a micro usb card, but not an adaptor so i'm clueless right now I've tried the phone on different PC's so its not the computer either.

Bad USB port on the phone or possible a bad cable. Did you swap cables too?

i have this issue randomly too. i find that by switching 'Enable Advanced network functionality' off or on (opposite of whichever setting it was when i had the issue) that the phone connects with no problem. i'm actually having a problem as we speak connecting to SOTI Pocket Controller, and i turned off the advanced network functionality and now it is working fine. Settings --> Connections --> USB to PC.

Right but that wont affect Bootloader mode. He said he has the problem in bootloader. That I think is a bad cable or bad port.

I've tried the phone in a different port and different computer, no luck. I dont have another cable but i'd be willing to get one. Would it be worth it for me to try to reinstall the ROM on the phone along with the radio?

No, I meant the port on the phone. The mini USB port. I had that go bad on me once. From me picking up the phone by the cable when I was tethering to desktop PC. Yeah, I dont do that any more.
Do you know anyone else with the same phone? if so have them try it on your rig with your cable. That will tell you right away if its the phone or not. Cant think of anything else to try without a control device.

So I picked up another USB cable and still no luck... I also flashed the phone to the stock rom, and no luck again. I think you're right about when you said it was a hardware issue.
Here's another question though... would it be worth it returning the phone now, and getting another phone of the same model, or could I just use Bluetooth for active sync, return the phone in 9 months, and hope they'll give me a better model.

Its always a roll of the dice on that.....if they still have Moguls in stock in 9 months, which I believe they will.....chances are slim for an upgrade.....but you never know...
Hey guys, I did try searching, but if I missed a post please link.
Problem is this: Randomly at the beginning of the week 3G stopped working, and along with that (probably unrelated, but never-the-less...) the phone, when plugged into any computer, would not be recognized ("Unrecognized Device" and under device status is it would say "This device cannot start. (Code 10)"). I did fix the 3G issue, but the phone still won't connect to any computer.
I've tried on computers with and without samsung drivers, with the phone both in and out of debug mode, usb storage both on and off. Currently on my PC it sees that it is a samsung device, but it has the yellow triangle, signifying that it still cannot start the device. Cannot ADB into it obviously, and cannot even get ODIN to see it when in download mode. Yes, I've also tried 2 different cables.
Using Windows 7 on all the computers I've tried it on (don't own anything older unfortunately/fortunately) and currently using ComRom 2 RC 2 PBJ (though this started on ComRom 1.3, and have tried the OTB kernel as well) thoughts?
Thanks guys!
Have you tried booting to CWM while plugged into the usb? That usually fixes it for me.
what i do is go to device managers look for your device and make sure the right drivers are installed once you install the drivers everything should be good

just gave that a shot. new dialog box popped up "usb device not recognized".
I'm probably going to try and go back to stock, but I'm not sure if that is really the issue.
Same thing here.. no idea what to do.. last time this happened I installed/uninstalled drivers until I thought I was going to puke.. even now I'm on a fresh install of Windows 7 x64 with SP1.. so .. this is really starting to suck!! Plug in the device and INSTANTLY "device unknown"... Yeah.. right!
Have both of you tried changing usb setting from mass storage to ask on connection? Uncheck usb debugging, go into usb settings change it from mass storage to ask on connection, go back and turn on usb debugging, then connect phone to computer.

I will do this promptly and post if there is a success story.. har har!! Thanks for the tip.. we'll see..
/EDIT/ Does nothing... nothing at all.. I hear the sound when USB is connected to Win7 ... then immediately says "unknown device" doesn't even seem to try and pull drivers.. it's almost ready to fly out the window...
/EDIT2/ Well I just got one step closer... I basically uninstalled ALL USB hosts, etc. Restarted, they installed.. then plugged phone in.. recognized, got the "installing device drivers", then FAILED to install... I'm lost.
Now here is the actual message that I am getting, I can only assume OP is too...
Windows has stopped this device because it has reported problems. (Code 43)

Oddly enough, I'm not getting that. I'm getting error 10, device failed to start. I'm sure these are related somehow.
Also, I did try the above suggestion, with no success. I did notice though after I unchecked "usb debugging", told it to ask on connection, then re-enabled usb debugging i get "no accessibility services" which I'm not sure is an issue, but it is never-the-less an error message. does everyone get that message?
thanks for the help everyone

I get that message everytime I check usb debugging. Just click OK and everything should be fine.
All I know is that it's out-right ridiculous.. I seriously doubt there is anything wrong with either of our phones since this has worked fine to this point.. I'm just trying to get back to stock using ODIN .. but can't .. I am so frustrated I can't figure it out..
Something interesting here.. I plugged the USB cable into a port and windows said it was an unknown device.. I just plugged the cable in.. bad cable issues??
I have been attempting to fix this very problem for weeks. Nothing has worked. It won't even recognize the phone in Recovery or Download mode (Odin or Heimdall). I'm getting tempted to request a phone replacement.
For me it started right after I installed blackberry drivers on Win7 x64. Does anyone else have this in common? Maybe recently installed other USB drivers? Perhaps the problem and the install are mere coincidence? Anyway I ordered a new USB cable so I'll give that a try.
Also, has anyone trided naven's format utility? I'm starting to think this may be the signs of the USB port dying.
I wonder.. will there be an issue for service if I have a rooted phone with custom rom installed? That's the only issue right now about sending the phone back.. and the more I think and mess around with it.. if I hold the plug snug in the phone and wiggle the cable some, I can connect and disconnect... I think my cable is messed up ...
I think I have my issue resolved... Usb cable is bad... My buddy has the same cable end to his phone charger and it will charge my phone... And now my cable won't even do that... Need to find a usb cable to verify but it seems these cables are very sensitive... Check your cable OP...

Just picked up a USB cable from Walmart .. not a bad deal and guess what? Fixed 100% ... Was a bad USB cable. Never again will I use the Samsung USB cables.. only lasted about 3 months.. LoL.. All fixed!!! YAY!!!! OP - I think you will be all set as well once you get your new cable..
Replaced the cable and I still have the error. =(
I'm not sure what else I can even try...
EDIT: Fixed it. Uninstalled all USB drivers from my system and let windows reinstall them. toggled USB debugging on the device and mock locations on and it works. What an odd problem..
I Also solved this issue with a new cable. I had tried a different cable and still had the same problem.
So I wasted much of two days troubleshooting. Finally arranged for a warranty replacement but still had the same problem. I was getting ready to do a clean installation of windows and it struck me. Try a new cable, even though the two cable test ruled that out.
I figured that was worth a try before rebuilding windows.
The new cable fixed the problem. The 2 cable test should have revealed this. It's possible I had two issues and the warranty replacement and the cable fixed it.
Sorry that a second cable didn't fix the problem for the person above me.

Installed ICS 4.0.3 on my sgh-i717, a few days later it stopped charging and was unable to be recognized on any PC. I connected it to Kies via wifi, put the stock att rom back on it, reflashed though CWM, flashed counter and still nothing, set it back to samsung, got a new phone.
THen yesterday (2 days after i got my new phone) I flashed the new OnlyOne ICS rom 4.0.4 on my phone, then not even 3 hours later, my USB wasnt working again.......charges when it wants, but CANNOT be recognized by and PC....wtf?
Any ideas please!!! ?? THank you!
USB Ports
Just out of curiosity, have you tried a different usb port? Sometimes (and I think it's windows fault) I can use something on a certain port for months, then it will stop working, changing ports fixes it, then when / if that port stops working i'll switch back to the first port I started with... rinse / repeat.
Remember the old Nintendo Carts, when they would get dusty, they wouldnt work until you cleaned them? Could be the same thing, issue with the port, dust, or just going bad.
It could either be a driver issue / and or the actual port. Esp if it's an older usb 1.1 spec port.
I am running OnlyOne, and it's running fine here as far as computer seeing it / charging. I don't think you would get 2 phones that are defective back to back, Check your computer first, especially if it consistently will charge with the AC adapter and not the computer.

Ouch..... Sorry Bud........
I hope you still have insurance on your phone and I would put it back to stock and see if that works out for you buddy.
If you have access to another phone , try to download seraphim a great from and put it on there and flash it. Inside of the newest seraphim there is a USB storage mount option which should fix your problem. I hope this will fix the problem

Doesn't sound like a ROM issue or one that requires a different ROM to be installed just because it contains a USB selection. To me it sounds like you have a bad cable or a few bad cables. I would try a new micro usb cable. I have had that issue happen a few times with quite a few phones. Cables that just don't click when inserted don't always make the proper contacts. And owning another cable can't hurt, just make sure it is a good brand.

I tried reverting back to a Gingergbread rom, tried re flashing a few different roms, no luck. Tried a few different usb plugs from different phones... how can you mess up a micro USB just from flashing... makes no sense.
Idk about the charging part, but i had the same issue with pc not recognizing my phone after i flashed new ROM on it and could not share files and what not i found a solution for that try this. Make sure phone is unpluggdd from pc. Go to settings>Wireless and network>USB utilities> connect storage to pc then it will tell u to plug your phone, do so. And phone should prompt you with the normal USB storage click it and your good to go.

My I777 has been acting up lately, and now I'm out of options and wondering what my next move should be.
For several days when I'd connect the phone to the PC via USB, it started saying "this device can perform faster when on a USB 2.0 port..." - which, my ports ARE 2.0.. transfers were taking forever. Now, anytime I plug it in it simply says "USB Device not recognized" - I've tried the OEM cable, the plethora of other cables, 4 different PC's... *ALL* have the same result.
My concern is with a custom ROM on it and no way to get any PC to recognize the phone to get it back to root - how should I proceed from here for warranty purposes? I've only had it since March - just wondering what's gonna happen at this point - or is this even fixable? All the threads I've seen say it needs replaced... but with no way to unroot, etc., I'm just unsure how this is gonna go.
Thanks for any advice.

You can always use Mobile Odin to flash back to stock since your on a custom ROM.

Absolutely NOT.
This is a situation that's been coming over a period of time, starting with the inability to see it as a USB 2.0 device when initially plugged in, and now has deteriorated to the point that it can't even be seen.

Yeah, I sure did - nothing. Even in recovery, it won't "mount" usb there either.
Samsung's have a crappy USB port. It fails sometimes. You have a hard time charging at all?
But like I stated above, even without a computer connection you can get Mobile Odin and flash back to stock, as long as your rooted.
I'm having this same issue. I just got the phone earlier this week and I am unable to get bit connected to my pc to root or Odin. I have installed and uninstalled Kies multiple times on two different computers, tries different ports, and checked if the cable worked by using another phone (PC recognized without an issue). I get the USB not recognized or the 2.0 USB message. If I enable debugging, I can connect regularly and transfer files through windows explorer. But if I use USB debugging off, then nothing will work. I've tried using odin and it will just get stuck at setup connection or cache.img and then I'd have to pull the device. I've tries updating through Kies when it shows the USB 2.0 message but once the S2 hits download mode then the computer stops recognizing it. I have also tried installing the i777 drovers on the Samsung website and its still a no go. Does anyone know how to fix this? Its not rooted so mobile Odin won't help me now.

It is the OEM cable that came with my Samsung Infuse. It worked with the T989 3 days ago and it's not working with my i777. Its strange because I tried it with my infuse again and I am able to Odin just fine. Could it really be an issue with my USB or will it be a PCB issue? I would rather or not disassemble my phone if it is a PCB issue. Should be able to do a warranty exchange though.

I hate to break it to you brother but it's damn near impossible to determine what the actual culprit could be, your best best is to try each and every single different thing I've listed. The end result being changing the PCB which one, isn't that hard, and two, is very cheap the only problem is waiting for the board to come in the mail.

Its strange because when I enable USB debugging, I can get a "USB connection" on the phone and data transfers fine. But when I turn it off, I get a "MTP connection" and sometimes it'll connect (5% of the time) and allow me to transfer data. But when lies tries to update when that mtp connection is active, it'll hang when the phone goes into download mode. Did you have this same issue?

I f you're able to transfer files via mass storage with USB debugging enabled then you can (most likely) rule out hardware failure on your phone.
If anything this sounds like a driver issue on the cpmputer. Are you running windows? If so remove and reinstall the drivers for your phone.
Still think its hardware.
I can connect 1/100 of the times I'm plugged into a computer. Its not a driver issue because my girlfriend has an i777 as well and no problems for her connecting at all.
Its not ROM related because I have this problem with all ROMs.

Does that apply to ums as well? From his description he can connect in ums just fine. Its only mtp that's giving him problems. In his case, with the problem only being in one connection mode, it leads me to think drivers. In your case, tested against another s2 I'd say hardware.
Just tried using a Motorola cable and a third PC and my chances of connection increased to about 15-20%. Kies and Odin failed on me a few times just like I had described before. But eventually Odin was able to flash okay. Finally on ICS on my i777! I think I'll stay on stock since I'd rather not go USB and PC hunting to flash stock if anything goes wrong.

Hello, all.
I have a straight talk samsung galaxy s3 sch-s698c I was able to flash cwm and lineage os 14 onto with no problem, but I have a couple of questions and issues, though:
1. what issues would be encountered if I activate this phone thru straight talk with a custom rom? I ask because I was unable to find the exact lineage OS build for the sch-s698c, but used the one for the Verizon model, the sch-i535, which DOES work. How do I activate this phone with that Verizon ROM on it? I haven't activated it yet.
2. I am having a weird issue with usb otg working. I am able to plug in one of those dual end usb thumb drives that has a micro USB end with no problems, but when I use an otg cable (which I had to order) and a USB stick, hard drive, etc nothing happens. I want to access the files on my laptop, which kicked the bucket, and the hard drive is still good and is connected to a sata to USB adapter. I have tried using various otg apps, such as usb otg helper, apps that detect for otg capability, and tried testing the otg cable on a phone that I knew had otg to see if the cable was bad, but it wasn't. When I tested for otg, the API was there in the os, but the system was unable to detect the otg signal. How is a dual end USB drive able to communicate with this phone, but the otg cable not??? I have also tried using the stock firmware for this phone, which I had backed up before flashing lineage os; no-go. What do I have to do to fix this?
Update:
I used a tool called "USB host controller" and it reports "no root hub found" and also reports "s3c root host driver was not found". What does this mean?? I tried to find this driver all over the internet, but it's a needle in a haystack.
HOWEVER, I run this program with the dual ended thumb drive plugged into this phone, and it reports a root hub and the phone in host mode. While this phone works with thumb drives that have a micro USB end, I still don't know why it won't work with an otg cable, SMH... Are there any circuits in the dual end drives that make otg work, or otg USB hubs that have such circuits?
Okay folks, I feel like a TOTAL IDIOT right now. I solved the USB otg problem by placing a sliver of a business card in the bottom of the charging port before inserting the otg cable. Apparently the otg plug fits too loosely in the charging port due to wear and had a bad connection. Now it works.
Now to the activation question...
What do you mean by activation? the sim thing? if its that i think you can do it only on stock rom

Activation as in getting cell service restored. To my knowledge, the phone does not need a sim if using stock rom. I was able to purchase a plan and activate w no sim, but only with stock. I couldn't activate it using a custom rom.
However, I did find a good thread on this with a little diggin: https://forum.xda-developers.com/galaxy-s3-verizon/development/guide-to-flashsetup-sim-apn-cm-cm-based-t3351290. According to this thread, i will need to get a deactivated Verizon sim and a BYOP activation kit for straight talk or something like that to restore service to an sch-s698c using cyanogenmod based roms intended to work with the sch-i535. I don't have a Verizon sim yet and would like to look into this later. What do you think?
