When it's in the download mode it may show up in a different location in the device manager and be listed only as "android".
Do you hear any sound from the computer when you plug it in when in download mode?
What does your download screen look like?
Once these questions are answered, there may be a solution. Hopefully a CDMA device won't be different

there are two possibilities.. First, your phone is already hard bricked.. second is, your battery is absolutely dead with no power left...
Well, Have you tried to check the battery itself?

how can i check the battery? its non removeable.
thanks for helping, any ideas is appreciated!

ok, so have you tried it using different PC or laptop?
(last option if nothing else to try) if you want to check the battery :
DIY remove the case ( there are several tutorials in youtube, but of course, do it with your own risk)

It's not hard bricked/
Getting into download mode proves this.
You must get your computer to recognize your device in order to communicate with it. So I would not consider anything else until that is accomplished. PERIOD!
1. Are you using a USB 2.0 port? usb 3.0 will not work a lot of the time. (Important)
2. Have you tried another usb cable?
3. I think we discussed the drivers, I have them if needed
What operating system are you using?
If nothing here helps we can we can use "TeamViewer 9" which will give me control of your computer to help resolve this issue...

[Q] USB device not recognized

I've flashed my i9505 many times. I can't remember exactly what I've done, but now the situation is very weird.
1. I can go into Download mode. But Odin doesn't recognise it. Kies doesn't recognise it either. The error message on the bottom right corner of the screen says "USB device not recognized. Your usb device has malfunctioned." I've tried re-install the USB driver, use the original USB cable, even tried it on another PC with no luck. I suspect the very low level USB driver in the phone has corrupted because possibly I flash something wrong in the past.
2. I can go into Recovery mode and flash new ROMs in zip format from there.
3. I can use my phone normally, e.g. make phone call, SMS, WiFi......My computer can recognize my phone as usual when I am in Android.
Any thoughts? Helps are appreciated.

Hello,
Uninstall any previous installed of Samsung USB drivers, clean your Windows registry through CCleaner (not needed but highly suggested) then download and install latest Samsung USB drivers
Now download mode will be recognized on PC
Inviato dal mio GT-I9505

There is an easier way. If you are using windows, go into control panel-> Devices-> Right Click on your phone-> there should be a Driver Details-> Go details I think it is-> Uninstall driver-> Have the box ticked-> Uninstall-> Unplug then replug the cable in and it should work.

I've tried to re-install the driver. I even tried to connect the phone to another PC where the driver had never been installed before. Nope.... it doesn't work. Actually, I've searched around in Google for long time. The most likely reason is the usb piece of Android code is corrupted. Well, maybe not android, it should be the lower layer of Linux. I previously installed dual boot system follow this link and I screw it up when I tried to upgrade the primary OS:

You said that in Android USB connection works.
The download mode depends on bootloader, that can't be touched in any way by Android, even you can't touch the bootloader.
It's also write-protected, you can only upgrade it through Odin or through an official OTA update, when flashed you can't downgrade and can't write on its partition if not through JTAG

Sorry mate, I am still stuck in Odin. Since I can flash new ROM via recovery mode and everything else still works, I give up.

Galaxy s4 i9500 doesnt connect to pc. Stuck in bootloop. No recovery or safe mode.

Okay so here goes. I've looked at the forums searching far and wide for anything that may help.
The problem is I have an S4 that had some battery problems. (swollen) so i replaced it out for a new one. The shop that I bought it from claimed that it was an original replacement battery (I live in Pakistan so finding an original battery was hard for me). So the phone worked fine for about half a month and now it's acting weird.
1. It seems to be stuck on a boot loop. but sometimes will start and run for a few minutes (random amount of time) and then go back into the reboot phase.
2. the phone does not go into recovery mode. The recovery screen pops up for a second followed by a no command screen and then phone goes back to boot loop.
3. the phone doesnt go into safe mode either. So i cant check if its a app related problem.
I tried to then flash a new recovery or the stock rom. The phone doesn't connect to odin/ nor Dr.fone for android.
-> Windows doesn't install the MTP drivers even though i have the latest version of KIES installed.
-> I have checked with a replacement battery the problem still persists.
Please HELP!!

Boot it into download mode, then try connecting it to a PC.

@GDReaper
The phone goes into download mode but the computer doesn't recognize it. It doesn't connect to odin and it says mtp drivers aren't installed..

[Help] No Recovery, Boot loop, and not recognized by Odin

Seems I've hit the jackpot, my phone's a potato. I had just installed king of nougat v9 and it worked fine until I rebooted into recovery by holding the power button and selecting recovery. At first it was in a boot loop and wouldn't open recovery or get recognized by odin, I read somewhere here to disconnect the battery so I opened the back cover and disconnected it which apparently ****ed the phone a step further now it's dead unless it's connected to a power source and after disconnecting it stays on samsung logo/download mode for a bit then dies.
On my old rom it was working fine except for the fact that I couldn't connect the phone to pc as storage, and it couldn't recognize usb devices I plugged in using the adapter. I took the phone to a repair shop and they said they replaced the micro usb assembly and it still didn't show up on odin, then a few days later they said it's a problem with the power IC and they replaced that then the guy said it worked once on odin then stopped again.
Idk what to do lol, phone's bricked or should I try a different repair shop incase these were idiots.
note: it says device descriptor request failed when connected to pc

Have you tried to reboot to the bootloader by holding down the power button, home button and volume down when your phone is at the android logo?

Then it means you must install Samsung drivers, so that the computer would recognize your phone. Try downloading smart switch or kies and that should also install the drivers.

or try different ver. of odin

Try clean install Samsung Drivers and other version of Odin. It should be (have to be) show in Odin after all of these.

"device descriptor request failed when connected to pc" sounds like a windows problem not android. You can check in the "computer management" device manager to see if the phone is recognized. I am going to assume not.

OnePlus 6T boot loop - Stock firmware, not rooted

Hi everyone.
My OnePlus 6T (A6010 version) froze today and it has been rebooting in loop since that. I tried a factory reset, nothing changed, always freezes on the loading "dots" logo then auto-reboot.
I'm on stock firmware and didn't root the phone. Everything is as it came from the box.
What can i do except send it back to the vendor ?

Flash it back to the stone age with this:

the phone is not recognized by the computer as a COM port with the qualcomm drivers :/
OnePlus Support took control of my computer to update themselves the ROM but as the phone can't get recognized they are not able to do anything.
