HELP-Serius issue USB DEVICE NOT RECOGNIZED IN Download Mode

Hi
my phone is running blisspop , cmw touch is installed . when i try to connect my phone to my PC , error message saying USB device not recognized , and saying device is malfunctioned.
i tried everything.
tried my phone with my friends laptop
changed usb cable
tried same usb with my friends G2 which is working fine. so this is not issue with USB cable.
so i tried to flash kdz to get rid of problem, i entered my phone "Download mode" my pc still displaying same error message.
is it hardware related issue?

It could be a hardware problem. I'm going through a similar case (but it's not a hardware issue though). By default you shold turn off the phone, connect the usb to the PC (not the phone) and then Hold Vol+ and Power, Until you see it entered download mode, THEN you plug the USB port to the phone.

install driver

tried just now otg cable with a usb drive , again nothing
just a week ago i was using it just fine with my pc
should i take it to a store to check my micro usb port??

noone??
today i replaced the screen with a new one witch had a new usb dock on it and the problem is still here
i can not connect it to any pc.
i cann't flash the stock rom because odin is not see it also

is it possible to be a rom problem????
i can't flash the stock one because of the usb issue
but i think i can download another lollipop rom to give it a try.

Have you made sure that it is set as MTP?
Setting - Storage - USB.

Check if the device gets connected in Fastboot mode. If it doesn't then it would be your USB.

sideload is not working either
usb is brand new and original.

is there a way to flash stock rom via recovery?

I tried turning on The MTP option in developer options , still no luck.

I really hope you found a solution. Ive been looking an answer for this annoying problem for 6 months!
Ive read almost 50 threads in differents forums about this problem but no solution at all.
- Tried changing charging port. Cost me a few dollars but no solution.
- Tried USB debugging on and off from developers menu.
- Did MTP+ADB option in *#*#0808#* menu.
- Turned Low Battery Dump "on" in *#*#0808#* menu.
- Tried 10 or more different original Samsung cables.
- Upgraded PC USB drivers.
None of them worked for me.
Hope you have made a progress.

MTP notification problem

I have Samsung grand prime SM G530H xcu.. i am experiencing a problem that mtp notification is not showing while connected to pc it only charges the phone.. I have tried many datacables and by connecting to different computers but no use.. i wantbto root the phone but cant be done wd out debugging and it shows root failed.. odin also did not detect my phone and pc also is not showing anything.. reinstalled all the drivers but no use..
Please help me in this regard..

Flash stock ROM

stock rom already installed..

Try ticking the USB debugging option in the developers option or vice versa. Another way is if you have another Samsung phone, plug that when the device drivers configure them completly then unplug that and plug this phone immediately

Uninstall driver and try again

Odin not detecting device on download mode

Help! i want to flash official firmware -GT i9500
In past i was able to flash via odin on same pc and now its not showing usb all driver installed
already try changing data cable and diffrent ports i even tried reinstalling win7 and diffrent version of kies and drivers
i dont have other pc or laptops . other samsung phone is showing on download mode on same pc.
odin only shows my phone when i pull battery while connected to usb on download mode and i can flash twrp recovery or
any small size file but cant flash full firmware its disconect after some seconds
it connects well on mtp mode and twrp.

I have the same problem with my S4. I tested J5 2016 and it is connecting properly with the same cable, drivers, etc, either with odin or in normal situations when phone is on. also S8+ connects with its cable and same drivers, etc. But S4 is repeatedly connecting-disconnecting, either in downloading mode or normal situations.
I installed this driver "https://developer.samsung.com/galaxy/others/android-usb-driver-for-windows" which is "SAMSUNG USB Driver for Mobile Phones 1.5.51".

Already tried it didnt work. i dont have disconnecting issue on normal mode i can send and recive via usb mtp to pc for your disconnect problem if it disconnect after phone screen off, go to control panel>sytem &security>power option>change paln setting>change advanced power setting>expand all usb setting =enable change to disable.
If anyone has solution to OP please reply
Thank you!

I eventually succeed! Nothing special just used my brothers' laptop (win 7). same cable, same driver (1.5.51).
My primary problem was WiFi and Bluetooth not working. I was hopeful flashing will solve it but unfortunately no. Seems a hardware problem.
With your recommendation (enable to disable) i saw no change with my pc (win 7).
