USB Problem! Help!

I have a Samsung Fascinate and my phone won't connect to my computer! A few days ago, I was on rooted stock and I noticed it wouldn't connect to my PC. I did a data wipe and installed MIUI and noticed the problem was still going on. I thought it was no big deal but now it is VERY annoying! I've tried it on my Windows 7 computers and one XP computer and none of them work! They all say that it can't be recognized. I have accidental insurance on it and the person at BestBuy mobile said I can root it without voiding it. I don't know if installing a ROM (MIUI) voids it or not. I'm trying to do an Odin restore and when I put it in download mode, Windows still says that it can't recognize it. I want it on stock before calling them about it. I'm thinking this is a hardware issue. Anyway to get it off of MIUI and back to stock without a PC?! :'(

have you tried going to settings/development and un checking USB Debugging? worked for me after update.

Yes, make sure USB Debugging is not selected, as this will prevent your device from entering storage mode and be picked up by your Computer.

Also, make sure that you're using the original USB data cable that came with your phone. Other cables might allow charging, but won't work for data.

or...
if still doesnt work, try a factory reset (sorry)

I am using the original cable. And USB Debugging is unchecked. It also won't detect my phone in download mode...? Could it maybe be the USB?

Did you download the ADB usb drivers? Also, be very careful downloading the Samsung Drivers and updating Win 7. They broke two of my computers.

[Q] USB not recognized

Hi all,
My Droid charge decided to do something weird today; it no longer will USB mount! This problem is particularly bad because, while I can put the phone in download mode, my computer will not recognize the USB and ODIN (1.2 & 1.8) cannot wipe the phone.
Any suggestions? I really need my phone back, but I'm not sure what to do.
Tried reinstalling the USB Samsung Drivers, using the original data cable, and two different computers (Win7). SD card will mount in an external drive (aka without the phone), and the phone will charge via USB. I have the most recent form of CWM on it, and the EP4P debloated and rooted rom.
Thanks,
frak

That happened to me a while back. Mine had the added bonus of going into desk dock mode and staying there. It was a hardware issue with the USB port. It would charge, but nothing else. Mine did become intermittent though, and cycling the cable in and out seemed to help it some, but ultimately, I had to send it in for replacement

What cable are you using? I accidentally grabbed my charging-only cable the other day and didn't realized it only had the wires for positive and negative. No data pins.
Is it the cable that came with your Droid?

Another thread similar. Check it out and try some.

Had that yesterday. A different port worked fine for me. Maybe a couple of power cycles will do the trick.

[Q] Cant reset Samsung Galaxy Tab 2 GT-P3113 back to stock. Cant connect to computer

Hello guys. I've been having this problem with my Samsung Galaxy Tab 2 7.0 GT-P3113 ever since I flashed Cyanogen mod on it. I would like to set it back to stock firmware but for some reason my PC wont recognize my tablet as a device. My tablet will charge and I also have USB debugging on but still my windows 8 laptop wont recognize my tablet.
So here is my problem in a nutshell:
I Cant find the stock rom for my tablet
My tablet cant connect to my computer
Please help me. I would rather not spend another couple hundred dollars on a new one.
Thanks!

The only way to go back to stock (factory state) is flashing a backup, which is recommended before installing Cyanogenmod or any other custom rom. Other than that, if you're lucky, you can try and find the stock firmware for your P3113.
The issue of your P3113 not connecting to your PC via USB: Try powering off the tablet completely. Connect your tablet to your PC via USB. It should install the USB drivers. When it's done, disconnect your device, boot up the tablet completely. Connect the tablet to your PC again with the USB. If you don't see a change, try enabling USB debugging. I had the same issue with my P5113. This worked for me.

how to bring back p3100 (solved)

I usually keep flashing ROMS.
This time in sheer confidence I didnt charge the battery full.
I was switching from mokee 4.4 to CM11.
I wiped everything for a fresh install and unfortunately CM11 didnt install.
The tab restarted and now it wont go into recovery. what just happened?
It is just showing logo and I cannot get into Odin more either.
The tab had about 30% battery when it shut off and I cannot reach a charger for it for the next 4 hours.

Can I switch it off in any way to save battery?

the phone has switched off now. Is service center the only alternative? the tab was rooted with mokee installed.

Try charging it when you have time and then try re flashing the stock Rom before taking it to service center

will the tab 2 charge without a recovery or ROM in place?

I think it should

Ok, the tab2 is charging. thank you
I installed all the necessary drivers and odin and recovery on my laptop.
The tab2 is giving error on pc (this device wont start) mtp uSB. THe tab is stuck at 'samsung p3100' logo.
If it is any help, I have a working p3100 also running on stock firmware.
what should be my next step? I think I can manage if only I can get odin to recognize my phone or get into recovery (both of which seem to be missing.)

Try reinstalling drivers

@shsagnik : Thank you very much for helping out.
I got installed all drivers by using the other P3100. But when I connect the bricked p3100, pc doesnt install MTP USB drivers. Under device manager it says " failed to start".
ODIN doesn't recognize it. either.
My mistake was I flashed everything on the phone including the internal memory.
PS: Can I force ODIN to recognize my phone?

Ok, my almost bricked device is back and runnning.
This might just help somebody. but my android handset was on a logo only mode. something in the combination of
Attaching it to pc (windows 7 64-bit)
re-installing and rejigging drivers
trying to let ODIN identiify
connecting via Samsung kies (I also tried restore on kies).
connecting a working android phone instead of the dead phone with pc to find and install drivers.
worked.
PS: I also let it sit dead powered off (worked only when charger was attached) for a whole day before trying to boot into recovery or bootlaoder (both worked).

The pc doesn't recongnise it on device manager (i have a win 7 pc), the phone however react as pluged in a charger.
their is no mtp or mass storage switch on notification.
i have reinstall the driver of samsung several times with smart switch & also made it manual by suppressing directrly the samsung usb driver from programs on control panel then reinstall it but no hope.
I can't figure out eitheir its hard or soft.
i had change my cable & also test my pc with another Galaxy s6 it works fine, but mine no.
i have made wipe cache / factory reset also made an initialisation from parameters the phone is formated but not recognised by the pc also test it on another pc but the same behaviour windows pcs doesn't recognise my phone.
However, i figure out that when its on the restore mode (volume down + lock + home) the pc recognise it by Odin and smart switch.
i install the same rom on it also made an emergency restore with S/N and model and the process completes fine with smart switch and i saw the donwload progress bar completing on my phone.
but still i m stuck its not recognised please help !!!
i tries to use *#0808# and its on AP / MTP + ADB but no hope

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.

Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem

i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.

Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you

I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?
