[Q] HELP PLEASE(Driver Problem)

My phone isnt detected by my windows 7 OS.
I connect it to PC using usb cable and all I see is that the phone is charging and there is NO USB mount option in the notification bar.
I re-installed kies about 5 times but no luck. I updated it to the latest version but still no luck.
Please help me out,

Hi Sir....
Have you try "wipe cache" or temporary files in your Computer (ex: with CCleaner) ?
And try to disable User Account Control too
I am also using Windows 7 with no problem when installing the Kies Software

try connecting device in another USB port, not ext , but in main USB port

yup...definetely worth to try. you may also reconsider to change your cable data since it could be the source of the problem.

yes.. the samsung original cable that is supplied with the phone has problems with me.. i used a BB cable data and it works well.. you might giving it a try..

and make sure that you r using stock rom cause kies wont recognize your device if you r on a custom rom....

Thanks for such a quick response guys.
I wiped cache with ccleaner and did a complete PC scan too. No luck.
I tried other USB ports too. Now im gonna try BB cable, cause I doubt my cable hardware now.

Thanks all.
Solved.

[Q] R800i usb port on phone problem.

Hello guys, just gonna state my problem and ask a few questions.
So, here it is. If I connect my phone to pc/laptop nothing happens, no notifs appear on my phone neither mtp or mass storage. But, when I connect my phone through electricity socket it charges up. Oh, another thing sometimes when I connect my phone to pc/laptop ports it charges up but still no connection to storage/or phone. This just happened last night after from my hospital duty and got home and tried to flash fxp128(love this work) and my phone wont be recognized at all.
So, I've searched up google not that deep but, I found some issues just like mine. Some said its a the laptop problem just need a restart, change cables, remove battery, try in different computer/laptop and etc cases like those. Alreadt tried everthing of those but non seems to work. So, i think my phone hardware(the usb port in my phone) is really the problem. My questions are:
It is repairable?
The repair fee costly or not?
Will this thing will likely come up again?(low chance/high chance of getting this problem again.)
PS: I remember that while on the hospital(free time) i tried to open the rom manager but it fc's when i try launching it.(everytime)
- and my 8gb type 4 sd is broken even through card reader it cant be read. ( dont know what caused this) so i change to class 2 4gb my spare card.
Hope you answer me guys, thank you!

tbh. your phone worked perfectly, and after flashing fxp128 you get problems and directly assume your phone is broken Instead of going back to stock and figure out if it really is.
Usb connection problem could also be caused by not having the com.sonyericsson.usbux "systemapp" or other things.

how can i go back to stock if my phone cant be detected in my computer? can't even go for fastboot and flashmode.

Did you make a NaNdroid back up with CWM? That would be your best bet at this point.

Did have a nandroid backup but on fxp 127. Tried to use it but still no luck. Any suggestions/ideas?

If you're using windows, try to uninstall the portable device at device manager window, while the usb is attached to your phone. Then disconnect the phone after you've uninstalled. After that reconnect it once more and see to it that the drivers are installed properly. It's usually USB mass storage or MTP USB device storage.

[Q] USB will only charge, no data connection?

I've been working on getting USB OTG / fast-charging working on my tablet, but now I can't get my tablet to transfer any data. Nothing when I hook it to the PC, ADB doesn't see it, if I put it in recovery mode it still doesn't see it.
I'm wondering if messing with the USB OTG/power killed my microusb port? I can still charge, just not get data. Anything I can try? I am using a certain car-based kernel, I was gonna restore to the stock kernel but would that be the issue if it doesn't even see it in recovery?

Damn, I have the same issue as yours! And I never even rooted my device! I only managed to connect to PC one day during which I flashed Android L, but now USB doesn't work again!

If the drivers are installed and it still not getting recognised at all, I thing the port that is used for charging/usb connection is damaged. It's cheap to replace one(1-2 dollars or euros), just get it to a service

No fast charging and no usb recognition by pc after update

I, after putting it off updated my phone to nougat. Immediately after I cant transfer file via usb and have lost the fast charging ability.
I have turned on usb debugging , totally reset the phone cleared partition cache etc etc #*0808# etc to no avail. Even went to samsung service center and they claimed have seen allot of these and no way to fix there.
Any ideas? whatsoever.......?

Maybe try flashing stock from sammobile site with odin. Must be a software problem.

Can't connect to computer to restore. Here lies the problem..........................

File transfer via USB not possible

Hey,
I have a problem. Since a few days I could observe that the battery drain are highly increased, up to 40% over night.
I decided to wipe my phone and flash the newest firmware MIUI10. I put a USB cable in my phone and connected it to my PC.
No response.. huh? Ok, just save my personal files via WLAN, no problem. Done.
I goes to TWRP and wiped all datas. Then I rebooted into Fastboot Mode (volume - and power), done.
I started MI flashing tool (in advance I've downloaded the firmware from officall MI website), connected my phone... nothing happenend. Tried several computers, I also tried to connect a USB device via OTG cabel in TWRP. Nothing works.
Whats going on? Any ideas? I'm really frustrated. The phone is just 6 month old, I flashed firmwares many times before. I think the problem is defective USB port.. but maybe I have just a simple logical error?
Thank you very much in advance.. and sorry for my english, I tried my best.
Best regards
René

I had a problem to transfer files, too. But it worked to adb sideload.
Is it recognized by adb?
