[Q] USB Not Recognized i9100 - Galaxy S II Q&A, Help & Troubleshooting

Hi,
S2 suddenly stopped picking up USB. "USB Device Not Recognised".
I've checked all guides and i cant get it to work. Its not my USB ports my S4 works fine.
I have replaced USB pcb many months ago no problem until now, it charges fine makes standard noise when i plug it in.
I assumed it may be due to custom rom, i tried to flash stock in Odin download mode but it does not recognise any USB device.
I'm kind of stuck and don't know what to do next hope someone can help.
Update: I'm going to try Mobile Odin, see if flashing original Stock firmware fixes it.

You can try to reinstall samsung drivers (http://forum.xda-developers.com/showthread.php?t=961956), see if that fixes it.
It's unlikely that a custom rom is causing it, unless the problem happened as soon as you flashed it, rather than suddenly not working.

Thanks, tired it no luck, I may have to replace USB PCB. flashed stock firmware with mobileOdin I hoped it would fix it.

:good:

Thanks for that outstanding contribution to the thread

Usb Problem

Hi there is it possible that that someone could mess up a samsung galaxy s2 by flashing an incorrect rom to it?
I bought one second had and the phone chrges fine but always says device not recognised when plugged in via usb.
Thanks rob
Yes, of course. If you flash wrong, your phone can brick. Try to flash an original rom without mods, using Odin, and see how your phone behaves. If it's ok, with the USB connection working, then you flash a custom rom and can really expect it to be fully functional.

[Q] USB Device not recognized

I am owner of the Galaxy S2. I updated yesterday to SuperNexus Jelly Bean ROM, didn't liked it. I restored my device to CM9 which i was using for a month without any problems. Then it started, computer couldn't recognize the phone anymore. Its like that SuperNexus broke something i don't know. I reformatted my Win 7 Ultimate x64 and installed fresh new CM10 - but after all my computer and S2 don't like each other - USB device not recognized. Chaos. I asked my friend to come over just to test with his S2 (he's on stock ICS 4.0.3 or 4.0.4), and when i plug his phone into my computer, everything works flawlessly. I tried mounting in recovery, i tried with and without usb debugging, Odin doesn't find phone neither, tried updating drivers - no luck... Dialing *#7284" just gives me "connection problem or invalid MMI code". Need help on this please!
You can check THIS thread. The one HERE , and also THIS thread.
I've read them all, tried every advice, but phone still isn't reacting to anything. So my problem is that phone couldn't connect to a computer, well it connects but it states "USB device not recognized", it charges but that's all. Everything started with Custom ROM SuperNexus. I've done these steps so far:
1. Reformatted my computer OS, which is Windows 7 Ultimate x64
2. Downloaded CM10 over my phone, get into recovery --> factory reset, wipe cache, wipe dalvik, format system, install ROM, wipe cache, wipe factory
3. I tried on my computer, tried on my old computer with Win XP x86
4. My friend's Galaxy S2 is working like a charm with MY cable on MY computer, which makes me believe that there is some defectiveness in my phone
5. I tried cleaning MicroUSB port with tooth pick, ear-cleaning pick (or how do you call it), needle with some paper wrapped around it, tried blowing in it
6. I tried with different USB ports, front ones, USB 3.0 - still no luck
7. I tried flashing Wanamlite and Neat ROM-s, still the same problem
I'm using Airdroid now, but i really need to know what's the problem! I have already ordered a new parts on E-Bay and I'm having high hopes about that solution. Im not able to post link to E-bay item, but search it under Item Number: 150904945773. Any other advice is really highly appreciable. Thank you
Try downloading the Rom over WiFi, or Hardline instead. Have you tried a different USB Cable ? Also I'm not able to check that Ebay # right now.

eBay item is this: New Samsung i9100 Galaxy SII S2 Charger Charge Port Flex Cable Replacement parts
OP, I'm hoping it works for you. You seem to be going in the right direction with your troubleshooting.
Well, i've downloaded this ROM (CM10) via WiFi, now i can do it over Airdroid too. But is there a way to flash Stock Original Samsung ICS in recovery? Or is it only available in Kies and Odin? I came across "Mobile Odin", do you guys have some experience with it, is it safe to use? How big are chances anyway that USB will work with stock ROM? Someone told me "your USB port on phone is OK, if it's charging it's not broken", so I'm thinking that it is not a hardware issue after all? And BTW i used several cables, and three different computers. My girlfriend have SGS3, i tried it like 2 hours ago with her cable on her computer with no luck (and of course her phone have no problems to connect to that computer using that cable). Thank you
I would try a Stock Rooted Rom, and see if that works correctly. If not try connecting the Device, and reboot the PC with the Device plugged in.
How to install stock ROM if i cannot get Kies or Odin to recognize phone? Via Mobile Odin?

Try USB solutions from My Android Solutions or Mobile Odin like http://forum.xda-developers.com/showpost.php?p=28302093&postcount=4789 ( procedure is same but written for Korean SGS 1
Guys let me tell you that I'm grateful to you, cause this Mobile Odin worked and my Stock Rooted ROM worked in connecting with PC. But not on first try when i got into a newly flashed Stock Rooted Firmware, i've let it to do his stuff, update what he needed to update blahblah. Then i tried to connect my cable - it didn't work. I cursed, i cursed so bad. Then i considered to give it another shot, rebooted the phone - and voila! Everything works, i tried 2-3 times and its working. Obviously SuperNexus started my problems, they couldn't be repaired by any other ROM i tried (i tried CM9, CM10, Wanamlite, old Wanamlite with MTP enabler, Neat ROM)... Then with Mobile Odin everything just worked. Dunno what really was the problem. Thank you all
Glad you got it sorted

[Q] i9100 detected by ODIN, but will not even charge from a USB when plugged in

Hi guys,
Its a bit confusing but I'll try to keep it as short as possible. It seems basically that I can charge fine in recovery and download but not in the ROM. Syncing doesn't work at all except download..
I have an i9100m. Ran NeatROM and RootBOX and dabbled with a few roms.
Now I'm not sure if it was the roms or wear and tear but I had ASSUMED until today that my USB port was messed. It would not even charge from a PC nevertheless mount as a mass storage on my PC. It can charge fine from an AC adapter.
Anyway, today I randomly decided to put my phone into download mode and what do you know, the phone detects, and I even see it in ODIN, so I guess my USB port is not messed afterall. Perhaps something with the ROMs and kernels that messed it up?
I think this was around the same time when my Triangle went away.... (I never removed it). In download mode now, it says:
Custom binary Download: NO
Current Binary: SAMSUNG Official
I'm rooted and not stock at all so I wonder if that's the cause?
I was thinking of downloading a stock TAR of my carrier and flashing through ODIN. Do you guys think this is sufficient to "Reset" it back to how it was all the way before? And then I'll root and go back to one of my trusted roms (and not mess around)
Thanks
Do you use the original USB cable to connect your phone? That could be an issue.
Anyways, I don't think that something is messed up software-side if you tried several ROMs.
Worst case is that the USB port of your phone is damaged =/
Gesendet von meinem GT-I9100 mit Tapatalk 4 Beta
Yes I am using the original cable. (all same result but obviously wanted to use the original just in case)
I was thinking the USB port was damaged too because after reading, I guess apparently I accidentally created a usb jig? (triangle went away + stats wiped...)
But that aside, if my USB port is damaged, how come when I'm in download mode, PC and ODIN detect a device is connected and it charges, whereas within the ROM, I get neither ???
Just an update guys,
I used ODIN to flash completely back to stock... and I still cannot charge from PC. Basically computer doesn't see the phone at all. So it has to be a damaged port.. unless theres something else other than the internal SD that I can wipe????? I wanted to wipe everything..
Still really puzzles me though... that ODIN can see it in Download Mode.
One of the mysteries I guess.
Did you try to clean your mini usb port on the mobile? It could help.

So....your phone only charges on DL Mode?????
Sent from the little guy
I have tried to blow some air in there.. any other suggestions?
Well, the computer only recognizes the device in download mode, Windows sees the device, otherwise it doesn't.Just strange that I was able to flash an entire stock image through ODIN but in the ROM can't even get the computer to recognize that ANYTHING is plugged in (or the phone to charge so the phone doesn't see anything either)
And again, whats even more strange is that i had that one cheap extendable USB cable that probably messed everything up (it removed my triangle..so I accidentally somehow created a jig?) is able to CHARGE the phone even in ROM but still the computer can't see it as a device. LOL
This is so messed. I guess my main thing is even if I go ahead to replace the USB port (get it repaired), do you guys still think this problem would occur... =\

I currently have the exact same problem, except for the flaky usb cable removing your triangle. Mine is still there.
I brought my S2 to a repair shop because i was sure it was my USB port, but the guy there told me it connected in download mode just fine so the USB port should be fine.
Here is what I tried so far
- cleaned USB port
- Used diferent cables
- Used different PC's
- Used different kernals
- Used different roms
- Re-formated/cleared/wiped everything I could find.
Did anyone find a solution? Should I still have my USB port replaced?

[Q] Help. usb stopped working

I have a samsung galaxy s3 with stock firmware. I've hade a few custom roms before but put it back to stock for some reasons. But now odin does't recognize my phone. Drivers are up to date, the usb cable is the same, other phones are detected (s2 and s5). i have tried other cables including from other s3's from the box. I tried to root it from sd but still no luck, so i can't put custom rom from sd. Is there any way to put a rom from sd without rooting? it can be stock, it doesn't matter(i'm stuck with stock recovery). Also I consider myself a noob, so any explanation would be appreciated. Thank you
No, there isn't. Try another pc or resolve the usb conflict on the pc.

The same thing on other PC's.
I can only suggest following the guide on how to flash with Odin very carefully, then try searching for similar posts that got resolved.
However, most I've read were due to drivers or leads -if your phone connects normally in MPT mode but not in download mode then it's unlikely to be the s3 is faulty.

It charges only...doesn`t connect in any way. Seems like i have to visit a service?
Same here!
Having exactly the same issue here! When connected by usb cable to the computer, theres no USB connection on the status bar. Just the ray symbol on battery to demonstrate the USB is connected.
I need to change my ROM, but even Odin didnĀ“t recognise my phone.
Some clue?
Thanks!
Ps: sorry for my poor English....
Same Problem
I have the same problema, after the installation of the custom Rom, in about 1 week, the PC no regcognize my Galaxy S3. I have test it in another computer with another usb cable. I need help, i need to put a stock rom without odin, i have clockwormod installed.

[Q] Samsung S6 Undetectable by Computer

Hello guys i'll try to keep my explanation short.
Device Samsung S6 Edge (rooted)
Not detected by ANY PC anymore, HOWEVER it does charge.
I Tried 5 different cables (new, original, old) cables do work so does the main PC
as my other devices are detected.
I have deleted KIES, SMART SWITCH , DRIVERS and reinstalled in the same order.
So, i flashed the S6 back to stock using TWRP (S6 was running Custom Rom XtrestoLite).
Still nothing, so i deleted all my files from the phone and flashed it back to stock again.
Still nothing, so i wiped the complete OS off the S6.
Now i'm here.
Try to change the usb mode it may can help

That's impossible as i've said my S6 has no rom and Computers do not detect the S6.

Tell me the status for now, S6 is running on stock or custom??
enable usb debugging and install usb driver again, also check in another pc/laptop whether they are detecting it or not.
Use Original cable and give a shot This might help you.
Also head over to Samsung's ofifcial Developer website and fetch the Samsung USB Driver pack which is about 15MB.
That generally solves the issue. Atleast for me!
I had the same problem think the usb board is damaged... you should replace it.
It was running a custom rom, but now the phone has no rom. I can only into download mode or TWRP and thats it.
So there are no options available on the phone itself.
I tried kies driver, smart switch driver, seperate driver from samsung website, i've also tried clockwork samsung driver. Nothing works for me.
Maybe it's the micro usb port that is damaged, but i highly doubt that.

Highly improbably that the USB board is damaged. Try different cables and before that, try it on a different PC. Sometimes it does work. My friend's S6 wouldn't read in Download Mode on my PC but it did on his.
Also head over to Run on your PC and type devmgmt.msc and check if there are any drivers missing.
I think the problem is the drivers
Install new drivers or find other samsung ... and try again
i've installed many drivers including the one that is 15,3mb in size.
guys it's not the computer because it does detect my tablet and my s7.
which also means that it's not the cables and believe me i have tried many cables about 8 cables now .
it's not the drivers, i dont know what it could be.
i think i'll order a new micro usb port and try that out eventhough i know that the usb port can't be damaged.
Unless one of you has a better idea, you are welcome to share.
Update: Hi guys, i've replaced the port but the phone is still undetectable by any computer.
Does anyone know what's wrong with this device?
Seriously, is there NO ONE of you guys with any knowledge or what?
I was going to say your usb charge port is damaged enough that it will charge but not transmit data but i re-read your post and realized you can't have a charge port issue if you able were able to flash stock rom. If you have teamviewer, pm me and i'll try to help you.
I have had this issue before in the past. Turned out that the cable was at fault. Swapped it and everything worked as expected, computer found it once again.
If it's not the cables as you claim, then you may have to ship it to samsung and request a replacement device.
