[Q] USB and internal memory broken?

Hi all, I think my galaxy is dead.
When I connect by odin, not detected when I connect as storage not detect it.
I formatted all thinking that would solve anything, but nothing has helped, still not detect it, and now I can not pass anything to the internal memory to flash any rom.
With my previous phone (Desire) something similar happened to me, USB break or something, but I could solve, but here I am lost, not to do to fix it.
I would appreciate any suggestions, I'm desperate.
USB connections ???
Replace Samsung drivers with new via Kies .
Or dead phone = service centre .
jje
Is there any way to eliminate recovery? I imagine that the SAT does not cover the warranty if I turn the phone appears to recovery ...
Uninstall and instal kies again
Check your odin version is it compatible
Flash stock rom and kernel
had the same problem now resolved

[Q] Computer not recognizing usb connector.

Hi all,
All up until a few days ago, my computer/s cannot recognise my Samsung Galaxy S2. Whenever I connect my phone to my computer, the phone believes I am plugging in the charger.
I have attempted to turn on/off USB debugger, attempted the USB mass storage connection method and also attempted to use Winamp's automount option.
I thought it could have been my cable and I have tried different cables and phones and it seems my phone is the only problematic one.
Before this issue, usb used to connect very easily, even used for my car headunit.
Yesterday I was running the 2.3.6 firmware and recently changed to 4.0.3 and neither allow the usb to be working.
Has anyone encountered this problem and does anyone have a solution for this problem?

Did the USB work on previous firmware if so you have messed up the install revert to older stock rom firmware and test .
jje
It didnt stop working due to a firmware upgrade. It randomly stopped working when I was using 2.3.6 so i thought maybe upgrading would do the trick, which it did not.
Try doing a factory reset..
Yeah, did a factory reset when I changed from 2.3.6 to 4.0.3 and just tried again. No difference.
I did notice that this error may have occurred when I may have dropped the phone. Not too sure how this would affect anything but just putting it out there.
Did you drop it with the usb connected?
Sounds like its a hardware problem, just try flashing stock again to be 100%

Dropped whilst drunk unconnected to anything, did have a case on it however.

ICS is not an upgrade its an unstable beta rom not passed by Samsung for use .
Possible dirty USB ports .

How would one proceed with cleaning the usb ports?
In the past I happened to have trouble connecting with the usb port and I solved unistalling and reinstalling Kies. Have you already tried?
I believe what I'm attempting to do is to even use the phone as a mass storage device. I used to be able to do this via straight windows to any computer and even my car headunit. However at the moment a cable is only recognised as a power source and not as a data connection.

just gave this a go, going to leave it overnight to dry. wish me luck
No luck but I have concluded that the USB port possibly could be broken. I'm wondering, does rooting the phone void warranty?
Unfortunatelly it does...
Wipe everything U can, flash back original firmware and do reset with factory JIG... Than U have chance to claim warranty. But its not 100%...
There is thred about reverting somewhere...

Try again but after restarting ur computer !
Does the computer see any external drives (whether you can connect to them or not)?
Does the computer make a noise when you connect or disconnect the phone?

[Q] S3 No USB OTG Connectivity after update on Stock 4.1.2

Hi can anyone Help me. I've got big issues with my S3 Runing the latest Samsung Firmware (JB 4.1.2; Germany DBT) which i flashed via Odin.
The Device is rooted and recognizes the OTG Cable no more, but the cable works. I tried it on my Fathers S3 with the same Firmware but without root. By the Way its the Samsung Original OTG-Cable. I Also tried other OTG-Cables on both devices. Same result.
My S3 is charging over USB and is recognized as mass storage (MTP mode) when connected to PC,so i don't think its a Hardware problem.
I rooted with CF-Root SGS3 6.4. But there must be something wrong, because CWM manager brought an error message and disabled the Backup/restore options. So i rooted again via Odin, but without a change, Problem with CWM-Manager and OTG still exist.
Then i rooted with CF Auto Root via Odin,but the stock recovery brought no change at all. CWM-Manager was Gone and OTG-cable is still not recognized.
Next step was to the Flash the Stock ROM 4.1.2 again via Odin. After that, root was completely gone, but the OTG wasn't still recognized.
So i decided to Downgrade to 4.0.4 Stock Rom again and Flashed it with Odin.But my S3 wouldn't even boot now.It hung at the Samsung Boot logo and did do nothing more. Then i booted to Recovery mode, did a Cache wipe and Rebooted. It still hung at the boot logo.
Then i tried to Flash JB 4.1.2 Stock Rom again (surely via Odin). There was partly succes. My S3 Booted again normally (no Root and still no OTG-Cable recognition). I rooted again with CF-AutoRoot so i can use my apps which need root access. But i still can't get the OTG connectivity to work.
Everything on this device is working fine on 4.1.2 except that OTG-connector issue.
I'm currently making a backup with Titanium Backup. After that i try a Factory Reset (Hard Reset) If that doesn't work i'm totally at the end with my nerves and go to a Hosiptal.
Why the hell does this not work?? I can't imagine what reason there should be.
Please can anyone help me:crying::crying:
I am currently on Omega v36 and the USB OTG works flawlessly...

Thanks for the Information, but not really helpful. I want to use the Samsung Stock Rom 4.1.2 without branding and root. And OTG don't work no more. I tried my cable on different I9300 fom colleagues Today running 4.1.2 Stock Rom (all without Root) It works perfectly on their devices. In the evening today i try a Hard Reset and hopefully my 4.0.4 Rom shows up. Then i'll upgrade OTA and root again with Autoroot. We'll see what happens.
Edit: Update:
Now i did a Full Wipe/ Factory reset. Downgraded to 4.1.1 then to 4.0.4 and back again.Made some wipes between the Firmware installations with Odin and tried my cable again. Still no USB OTG connectivity with neither of my two cables. So at the End it seems really to be a Hardware problem, although Charging, and MTP mode are doing well.
At last i will send the device back to my vendor to get it repaired in Guarantee.

[Q] Has my SII's USB died?

Well, the day before it occurred to me that I'd like to install a custom ROM, therefore I went on to plug my phone into my PC and for my surprise, the phone didn't pop that MTP warning and the PC did not recognize it.
So I went around and changed USB ports, cables and PCs, same thing.
Decided to try Mass Storage mode, when I press the START button and put in the cable it goes back into the main start screen.
So I went on and tried that *#7284# trick people used since apparently 4.0.3 bugged some crap stuff in the phone, no success either.
Strangely enough I can connect the "pendrive dongle" and it will map pendrives.
Well, I don't have my phone rooted or with SU so that means CWM from app store won't be able to install the recovery module, and I can't install... you get the picture.
Nor ODIN nor HEIMDALL will recognize my phone in recovery mode, wich suggests that the data lanes on my phone went somewhat dead.
Finally, any cable I plug in the phone says it's charging my device, wich leads me to belive that the usb port is dead.
Anyone had this issue?
Anyone can confirm me I'll have to take it to Sammy's assistance?
Sure looks like the USB is dead/dying.
Sent from my digital submersible hovercraft.
So I got one more question, can I root and/or install CWM so I do not stay dependent of the USB to update it or I do need to plug in the USB to install CWM through ODIN?
Several problems
It can be several reasons
1.the usb is dead buy new
2. try factory resetting the device
3. install kies on pc it will install all the drivers that you need
4.your usb port(of the phone) is dead
I had the same problem pc was saying "USB cannot be recognized" I TRIED EVERYTHING from factory resetting, changing pc usb ports, changing usb, changing kernel, roms, trying on other pc, reinstalling kies and drivers but nothing. The problem was in the usb port on the phone where you connect the charger on the phone. That part is weak and so you have to change it. Take to customer service with your warranty and they will fix it without charging anything just tell them your problem and say that you read that most of the galaxy s2 users have this problem and that you didn't touch the hardware of the phone

Warranty has already expired.
Kies was installed on the PC, ODIN gives no info @ COM port.
I wanted to connect it just to root and install CWM so I can swap ROMs as much as I want.
Thing is, the customer service wants 1 week to assess the issue and probably 100USD to fix it.
So for some god-knows-why reason my phone decided to conect to MTP while charging, I quickly restarted it into revocery mode and flashed CF_Root w/ CWM5.5.
Successful!
Bloody USB thingy!
Now I can start messing around with the phone.
Anyone has a n00blet guide on ROMs?
I was thinking about moving to CM 10.1, one of those nightlies running 4.2.2.
This is the one I used >> CF-Root-SGS2_XW_OXX_LPE-v5.5-CWM5
Can anyone suggest actions?
For future you should change your USB-Port. Here we get one for about 15 € (about 20 $) in ebay. It's very simple to change and then you have a full working phone again. Just watch the Videos on Youtube and everyone can do this. Hope I could help!
