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] Xperia J Failed Upgrade.

Hi guys!
I would seriously appreciate help with this case.
I have friend's Xperia J on my hands, trying to bring it back to life.
The situation is like this:
The phone had failed upgrade to Jelly Bean (I have no specific info how that happened). Now it boots, goes through 'Android is upgrading' phase (optimising applications), goes to homescreen, and then after a few moments a lot of crashes happen (for example "Unfortunatelly DownloadAgent has stopped working") and after some time (usually 1 min) phone freezes and restarts.
To me it seemed like an easy case - just reflash stock firmware and we're good. So i've tried repairing through PC Sony Companion, but when I am told by software to put the phone into flash mode (vol down + usb cable) it just sits there not detecting the phone. I've tried windows 8.1 and windows 7 machines and usb 2.0 with sony cable.
Next, I've tried flashtool, also installing flashtool drivers. When I'm told to plug usb cable, it only goes to 'Reading device information' and just sits there. (Green led is lit).
When I check drivers with phone in flash mode this is what I get:
11/029/2015 13:29:56 - INFO - List of connected devices (Device Id) :
11/029/2015 13:29:56 - INFO - - USB\VID_0FCE&PID_ADDE\5&212AC8FC&0&3 Driver installed : true
So, I'm kind of out of options here, and any help would be appreciated! Also, I suppose that 'USB Debugging' is not turned on, it is hard to check with all those crashes happening, but I dont think it matters.
Thank you for any suggestion :good:

Try with different cable, and connect it on back usb port. I had problems with flashing with original cable that comes with phone, now i use short 10cm from Nokia. I haven't had any problems since.
Good Luck.

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?

Galaxy Note N8010 - Can't read USB

Hi,
I've had some problems with my N8010 recently. I reset it and am now finding that the laptop won't recognise USB (comes up as malfunctioned).
It's been rooted.
I can enter ODIN by pressing home and power up and can also access download / install customer OS by pressing home and power down (although it just sticks on "downloading").
Thinking it might be the USB (although the tablet was being charged when it was plugged in) I've tried a few but all have the same problem.
I've tried re-installing drivers via device manager, have tried the USB cable connection error in Kies (that goes very quickly through it's analysis and doesn't fix it).
Given I've done a complete re-set there are only the basic apps on the device (other than SuperSU - although I've done a full unroot).
Any other thoughts as I'm stuck and can't fix the issues.?
Settings:
GT-N8013 (although it is GT-N8010)
Android 4.4.2
Kernel - 3.0.101 Boeffla Kernal 3.0-beta6
Build - Gnabo.Rom.v8

Can anyone help?

G920F, USB MTP, FASTBOOT not working anymore.

Hi all,
So I have a strange problem, a while back I discovered that I can't connect my S6 to my computer and or other computers, whatever usb cable I use the device is not detected at all. and only charging works.
I already tried more USB cables and validated they work with other devices, I also discovered the USB is not detected in fastboot mode, so I can't flash any images anymore over USB.
I also discovered that I might have flashed a wrong stock rom a few months back and I never tried to connect it to the USB in the meanwhile, when I trace the baseband version it says it's Asian..:crying: And this device is a dutch PHN. The device has ADB working over WIFI and root enabled, it also has TWRP installed and even there MTP is not working!
However i'm afraid there is no way I can flash a stock rom back to the device without a working fastboot, unless there are flashable zips.
What do you guys think?
- MTP does not work
- Fastboot works but USB is not detected (odin, device manager etc).. with all kinds of cables.
- ADB Shell + Root Works (Only over wifi)
- I got a full backup of all partitons, created it with TWRP.
- It's stull running android 5.1.1
Best Regards,
Toetje

I can´t belive it, someone who has the same problem then me. A little wierd is that I got 2 phones here.... Got my S6 which I´m using atm and some days ago a friend gave me a A5. Actually the A5 has exactly the same problem and one more problem is, that the "Home Button" of the phone is not working. No chance to root it at all.
It was like this.... I came back home with the A5 and first I thought about was rooting it. Restarted and tryed to go into "Recovery Mode" which wasn´t working, same as going into "Download Mode". So my first thought was that some of the buttons arn´t working. I was right, it was the home button which is without any function. My next idea was rooting over Laptop with Odin. Enabled USB Debbuging, connected a data cable..... and usb connection was not working... only charging!
After like a minute of trying and no success I wen´t eat first. When I came back i tryed again and USB Debbuging asked me to accept the Laptop. (Till now I didn´t thought about that it could be my first and my last time I will have a working USB connection.)
I wen´t into "Recovery Mode" thought about restarting cuz I wanted to go into "Download Mode". So I restarted and that was FATAL.... since then I had no chance anymore till yet to get a working USB connection. No matter which PC, Laptop, USB / Data-Cabel. And since the "Home Button" is not working, I don´t even know how to get Root.
Right now I´m asking myself if it could be a Firmware related problem?! I mean, when my friend gave me the phone there wasn´t the newest update installed on it so I just updated it. It´s a A500FU running stock Android 6.0.1 newest DBT Firmware..... and also I´m not able to change it without having a working USB connection.
Greets!

I ordered a new USB port board, will let you know the results!

Any results after changing the usb port?

Did fast charge still work for you? And this replacing the USB port work? I think this is related to a broken USB ic. For me replacing the USB port didn't help

Sometimes it's a bad charging port and / or liquid damage to the charging port.
If your home button clicks but does not work it could be liquid damage near the home button. Same goes for power and volume buttons.
I just fixed a S6 edge plus yesterday power button not working, liquid damage all around power button area, fixed burnt components and corroded pins.
