1. Are you able to enter the recovery menu?
2. Are you able to enter the download mode?
3. Do you hear the USB connected sound on your Windows machine when you connect the phone while the phone is in download mode?
4. Have you tried different versions of Odin? During my researches I have found a site which recommends 3 different versions to try (AndroidSage: Download Latest Odin 3.13.1, 3.12.10, 3.12.5 Tool For All Samsung Galaxy Devices).
5. Have you tried installing a custom OS again or the stock Samsung OS?

1. unfortunately not
2.yes, this works fine
3.no
4.I tried just 3.14.4
5.I am trying installing stock firmware

I assume that you know that there is a warning before entering the download mode which you get rid of by pressing the volume up button.
Are you sure you are using a USB data cable and not only a cable used for charging? The first one usually has 4+ wires and the second one only 2.
If you are sure that you are using data cable then you can try doing different stuff to your phone (like turning it on and off, entering download mode and exiting) while connected to the PC and listening if any sound comes out of your PC.

loop boot quickly

Sorry for my English I will try to explain my problem.
After rooting everything was fine, but when I try to flash stock firmware somethings happen.First problem is that my PC cannot detect the phone with Odin and adb or mass storage I am 100% sure that the problem are not the drivers because I root that phone on the same PC before a week and of course I try everything on a another computer, but without success.
Download mode Odin cannot detect the phone! after many attempts to fix usb problem now the phone cannot boot , only in recovery (loop)after every start it's show recovery with message
Filesystems:
system: rfs
data: rfs
cashe: rfs
maybe system, data and cache files are erased I don't know.
recovery version is 0.1.3.b5
How can I flash stock firmware without PC. For example HTC devices can flash from SD card - Gold card, and PB99IMG.zip (I can't explain very well what I mean sorry)
Maybe the phone is usb bricked !
working..
recovery - only recovery
Download mode Volume Down + power off + camera ) - but cannot connect to PC and Odin.
not working
after flashing new costume ROM - the same thing - reboot to recovery
installed software on pc
android SDK,Kiesmini_1.0.0.10075_1,Samsung PC studio 1.5.1.10064_2,Drivers for spica on (Windows 7 x86)
really I cant find post like this !!! and sorry for my English
If you can go to download mode and phone is not detected, then you have bad drivers or bad usb in PC. Try another PC.
I have 3 pc and 2 cables and the same problem cannot detect. Can I flash new stock firmware without odin ?

Have you tried different USB ports, specifically one on the back of the PC?

Calm down. Did you read what I posted above? I said nothing about drivers. Have you tried other USB ports? Most people find the ports on the back of the CPU work the best, not ones on the front, or on a hub. It does make a difference.

[Q] Trying to root with stock 4.4

I am trying to root my Samsung Galaxy Note 3 (well actually i would like to install a new rom and recovery) , but i am running into a problem.
Odin3 (v1.85) only finds my phone when i am not in the recovery mode (or the sideload to be precise), adb on the other hand is able to to do sideload but the loaded images fail with "Wront footer" and "verification failed".
Some Data:
AP: N9005XXUENA7
CP: N9005XXUENA2
CSC: N9005DTMENA2
Model: SM-N9005
Android: 4.4.2 (Stock, no root)
USB Debugging: On
Reactivation Lock: Off
USB Driver: Kies 3 (also tried the CWM Drivers)
If you have KIES installed it doesn't play nice with Odin, remove KIES or kill all KIES processes and try again.

Thank you,
i removed Kies and tried again, i still don't get "ID:COM" in Odin.
Sorry I should have said, once you uninstall KIES you remove the USB drivers, you need to install them again. Again, sorry should have said

No problem,
i actually installed the "SAMSUNG_USB_Driver_for_Mobile_Phones" Pack after removing Kies and doing the reboot stuff.
Still don't get the device via odin.
Maybe i will remove all the drivers and try the CWM Driver again.
Try a different USB port - Not sure why it's not showing for you

I tried different Ports (USB 2 and 3), different Cables and different drivers.
Removed Kies3, tripple check that debugging is on and recovery lock is off.
Still, Odin finds the device when it is not in recovery mode (sideload),
Was another user who had the same problem had to use another PC, I'm struggling to think of what may be the cause.
I had also the sane problem. I also tried all ports on my PC but did not work. I installed KIEs on my Laptop and it worked. I could flash the CWM recovery.

Put phone in download mode then with Odin NOT running, plug USB cable to phone. Finally ran Odin ( I'm assuming you installed Samsung USB drivers ).

I did this on a new computer that never saw an Android device before.
Odin does not detect my device despite following this advice and the one before.
I installed Kies, made my device known to the Windows Device Manager, rebooted, connected device while in sideload-mode and waited until detection was finished. The next step was firing up Odin3 v1.85 and my device didn't show up, but i was able to use the adb sideload which failed with "Verification Error" when installing a new recovery or rom.
Could it be that the phone being branded by T-Mobile Germany changed the game even though the model is just plain SM-N9005 ?
Is there another option to root this device or preferably install some other rom without Odin?
Never ran into so much trouble with my Asus eeePad, the Samsung I9000 or the HTC One X.

Well when stupidity strikes you...
I always went into the recovery rom (Vol+ & Power & Home) instead of going with the odin mode (remove battery, power device on with Vol- & Home & Power).
Thanks everyone who tried to help me, but you were no match to my blindness ^^
Maybe this might help someone who utilizes the search function after he or she didn't read the tutorials carefull enough.

PC&Odin not able to detect phone via USB after flashing custom ROM: tried dif pc too

PC&Odin not able to detect phone via USB after flashing custom ROM: tried dif pc too
Hi all,
I've recently flashed this awesome ROM: [GearCM][i9500][4.4.4] Optimized CyanogenMod 11 for Samsung Galaxy S4 [20140912] in my device. ROM works great, very stable, fast performance, however since install, I am not able to detect my phone via USB. Not even ODIN sees the device connected.
Was doing my research before posting, so I will let you know what I've tried which was recommended in other posts and google:
1. Re-installed Samsung USB Drivers: No Go
2. Used different USB Cables (using stock one that came w/ phone right now): No Go
3. Tried different USB Ports: No Go
4. Tried a different PC: No Go
5. Yes, I am testing with my screen unlocked
Anything else I can try? Maybe a setting in my Phone?
Thanks!
Odin should always see your phone in download mode. No rom will change that.
If Odin doesn't detect your phone in download mode then it's either a:
- Driver problem
- Cable/port problem
- Faulty usb port
By the way, the device charges normally when connected to my computer USB.

Good call. Odin is not detecting the phone in download mode-- so I guess we can eliminate problem in the device configuration.
I'm going to try again in another PC and different cables. Maybe my Cable went bad, sucks because it's pretty new? Going to copy Odin to a pen drive so I can try in friends computer. On other PCs I only tried connecting in Windows-- no download mode & odin.
Ok, so I was able to get working back.
I enabled developer options by going in about and clicking the build 7 times. Proceeded to go to Debugging options and selected Android Debugging marked. Reinstalled Drivers again, then it showed PC connected as Media Device on notifications. I clicked there and changed to Camera PTP and then back to MTP.
Now I'm able to see the Device again!
No idea why I was not able to see it in Odin while on download mode, however, I can see it now even when not download mode.
Thread can be closed, thanks!

Unable to flash any rom after Odin flashing error

My Note 4 is n910cq with Exynos and I downloaded Android 6 from an xda thread and while I try to flash it through odin I got an error. After that the phone stuck with a screen says"firmware upgrade encountered an issue please select recovery mode ın kies and try again". I can put the phone into download mode but not able to get it to recovery mode. I tried to flash older roms but still keep getting error in odin. I tried Samsung smart switch app through upgrade section but no result. So, what to do?
it happens to me also because the phone disconnects while flashing , so you need to change the usb port ..keep trying to place it in a different usb port or even try to change the usb cable

Thanks a lot. I changed the cable and PC and works good.

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..

Did you install the Samsung drivers? Windows won't do it by itself.

Then try a different USB cable.
Try a different USB port, different computer, and different OS.
