Rooted T989 won't connect to computer

So my phone won't connect to the computer, I have tried everything Kies on Mac, Kies Air, and Kies on PC and none of it is working.I'm running LiquidSmooth rom if that makes a difference. Please help.

I had the same problem on CM10. I fixed it by doing the following, i had to pull the battery and wait 30 seconds. Then reboot into recovery, then reboot into the ROM. Then by plugging it in, the USB storage icon should appear
Let me know how it goes.

You could also try uninstalling and reinstalling the Samsung driver for your PC.

so i did a pull, got into recovery, booted back to the system, plugged in and usb did in fact work.. however.. once i disconnected and tried to reconnect, it would not.. even more battery pulls wouldnt let it reconnect..

Try reinstalling/flashing the ROM again, along with GAPPS and the wipe (if you're in CM10 by installing the wipe, then CM10, then GAPPS) or if you're in something else, try reflashing if the USB connection bothers you

Thank you so much for this Umar, it was so simple that I have never thinked about this solution.
After trying on several different computers, with different cables, cleaned my phone mUSB mother connector with alcohol and put in some compressed air, changed 4 different ROMs, your solution solved my issue and now it works like a charm.
Thanks again!
:good: :victory:
LE: I didn't boot into Recovery, just Powered OFF my phone, pulled out the battery, waited about a minute and turned ON the phone.

[Q] T-Mobile Galaxy s4 (First Root)

I have a T-mobile Samsung Galaxy s4 and this is my first root I've ever attempted.
Been trying to root my device for the past 5 days using various methods which include towelroot, odin 3.7, odin 3.10 and other methods. I even watched the video how to root it from xda. But I am just not having any luck. I have everything updated on the device thats updated from kit kat 4.4.4 and everything is stock.
Odin is just not connecting to my device while in download mode and I have also updated the usb driver as well from the samsung website. and when i plug my phone into my computer while the device is on it recognizes the device on my computer. So I really do not know what to do now.
Any advice or suggestions that I should part take on?

Download Kies and let it install the drivers. Once done you can remove Kies.
I use Odin 3.07. If Odin sees your phone use CF-AUTO ROOT to root your phone.

i did just that and retried and did nothing towards connecting during download mode

Are you opening Odin after you plug the device in? If so does it say a message, something about 'added!'

I tried both:
-connecting it before opening odin
-connecting it after opening odin.

I think I'm just not ment to root this phone haha
but it does not say anything about being connected.

Try different usb ports, down to the last one.. If the problem persists it might be the drivers.. In this case, uninstall kies and install drivers from Samsung

i have done this as well. could this be my transfer cable? the computer recognizes my phone when the device is on. but when the device is off and it download mode it doesn't install the driver. I hear the negative sound when i try and connect the device on my windows 7 laptop.

I will test the theory later tonight in an hour. I'll keep you posted, thanks for your help =]

Tested the theory of the 'aftermarket cable'
used my original cable that the phone came with, and it still did not connect while in download mode.
I have no clue what I am doing wrong.

Do you have kies installed? If so uninstall it, reboot, and try again

I have the Samsung Galaxy Tmobile with same dillema.
Been trying for 3 hours on my first root as well with one successful passing root that did not root like it said.

What method are you using?

Method used
I used Philz touch 6.08.9. A tar MD5 file
---------- Post added at 12:30 PM ---------- Previous post was at 12:24 PM ----------
And Odin3 v3.09
---------- Post added at 12:37 PM ---------- Previous post was at 12:30 PM ----------
it said it was successful but when I ran a check for root it came up negative

I had a similar problem once, chased it for hours to find a usb problem. Best test for that is connect the phone via Kies (usb, not wireless) and try to transfer files. If you can't get a file from your phone to the computer you have a hardware problem: usb port, cable, computer, or in the phone itself.

[Q] LG G3 Unbricking steps clarification

This Problem is solved and worked successfully
wouldn't fix or unbrick my phone without the help of these guys , all my respect goes to ::

Hi XDA
i didn't want to make it a long thread but i have to , bare with me here :
first i followed that topic on XDA : http://forum.xda-developers.com/lg-g3/general/guide-update-to-lollipop-root-bumpd-twrp-t3048845
i tried to install twrp with imageprep but after rebooting it says secure booting error or something like that
i also tried this after that but with the same error https://www.youtube.com/watch?v=2we1YDc5JGU
but always the mobile was rebooting and opened like nothing happened
so i searched the internet for a solution i tried this one : https://www.youtube.com/watch?v=4YZ0i6aFsfM
but i guess the file attached weren't compatible so it ends up with an error before doing anything so there was no option except this : http://forum.xda-developers.com/lg-g3/help/help-secure-boot-error-trying-to-boot-t3054977
and here comes the misery , cuz i just got my phone and after the step while you write the commands in the android terminal emulator
and BOOM everything went black
NO BOOT , NO RECOVERY , NO DOWNLOAD MODE , absolutely NOTHING :crying: i freaked out a lot , but after searching for 3 days i've found this xda thread : http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
sadly i'm now on LGE AndroidNet USB port (com 11)
and what i'm getting from this thread that i've to short circuit two pins in my LG G3 Motherboard so i can switch LGE AndriodNet USB Port to Qualcomm 9008
Before anything else i want to make sure that i'm on the right track so just want to approve these steps :
1- open the phone
2- to make the device read as "Qualcomm 9008" not as "LGE AndriodNet USB Modem" i have to :
a- short cut the pins in the photo you provided "without the battery" for 3 minutes
b- connect the phone with the USB cable in the computer "without the battery"
c- my PC will detect the device as "Qualcomm"
3- after that i'm good to use your LG G3 unbrick method
are these steps right ?
just need to know when to plug in my battery and when i connect the phone with the cable , the pins must be connected or i can just connect the pins for 3 minutes and then remove the connection between them ?
Please anyone answers me with the exact steps or give me a short video on how to do it alone because i'm still rookie at these stuff
thanks xda members :fingers-crossed:

Am i posting in the wrong section or what ?

If you have asked for help in the threads you have linked, without receiving a response, you can try quoting someone that may know or use @ before their user name like @sd_shadow
This is a very technical and likely very few people have even attempted it, so it may be awhile before the right people log in to XDA and see your post.
This thread will be moved to G3 Q&A, Help & Troubleshooting

I too am having issues with my LG G3 trying this method but the thread linked has been closed.

Hi, i just solved this problem like just an hour before. And yes all your steps are right but make sure you select same port in the tool too,
And do not remove the connection between pins until your device recognize as Qualcomm

How long did it take for your computer to recognize the phone? I'm having trouble shorting the pins... Very small points that you have to hit. Also does the screen turn on or stay off when you do it correctly?

Maybe @os_man can help you with this error. i'm exactly not sure about this error.

here are the drivers http://www.androidbrick.com/?wpdmdl=3173 both 32 bit and 64 bit but remember that you have to turn off driver signing if using a 64 bit OS.
I'm back to the same thing that I had before just the lg logo and it keeps rebooting.

S4 mini does not turn on, and does not work recovery mode. Works only download mode

Hello,
I have a problem with a s4 mini i9195.
The phone dones not start and don't start the recovery mode.
I try to flash a firmware with Odin, but don't worws, Odin it blocks on:"initialization..." or "SetupConnection...".
I think this is due to the fact that it is not active the USB Debugging on the phone.
It is possible? if yes, how i can fix the problem? can i activate the usb debugging in download mode?
Thanks in advance

Same problem here. Even playing around with pit-files etc didn't help.
Have you found a solution?

You guys might have tried it but i will still say it. Try antivirus off, Install kies and samsung drivers. Close Kies from task manager. Run odin as admin and Change USB slot or try another USB cable.
I got this initialize error two times and it scared the **** out of me, i thought my phone is gone. but by turning off antivirus and changing usb slot it work.
Hope you guys fix your phone

did anybody resolved this problem?

Bootloop on download mode.

Hello everyone,
I've tried to flash a rom using odin on my J610G and it failed. Now while trying to get into download mode the device restarts automatically. It's recognized by the computer but it won't stay on download mode. It won't boot into the OS since it prompts "An error has ocurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
I tried the smart switch but it won't stay on it, It keeps restarting. Any suggestion ?

I have the exact same problem too! It's so frustrating coz I just can't get my phone to stay on Odin mode without it restarting to that stupid error screen:crying:

Simple. Charge your battery with the mains charger, its flat.

Did you find a fix?
