USB debugging & download mode not working

I have an infuse on uclb3 and I decided to flash aokp. I downloaded the rooted heimdall package and my phone wont show up in download mode.
So I decided to root on PC but USB debugging wont show up at all. Any ideas?
Sent from my SAMSUNG-SGH-I997 using xda app-developers app
So you are in ulcb3 stock without root or cwm right?
You made sure your phone was entering download mode when trying to use heimdall?
Edit: in settings > applications> development there should be an option to toggle usb debugging on or off
Sent from my sweet and buttery Infuse
I know both of those but the adb icon in the top doesn't show up and download mode doesn't show up in Odin or heimdall
Sent from my SAMSUNG-SGH-I997 using xda app-developers app
Sorry I'm not quite understanding you :/
An adb icon where exactly?
For odin or heimdall to detect your phone you must first place it in download mode by:
-Remove battery and put it back.
-While holding vol up and down, connect your device to the Pc
If it still does not recognize your device then it could be the drivers
Sent from my sweet and buttery Infuse
I got drivers installed and I can connect and transfer files just debug/download modes don't work or something
Sent from my SAMSUNG-SGH-I997 using xda app-developers app
There SHOULD be an adb icon in status bar when USB debugging is enabled there's none on mine
Sent from my SAMSUNG-SGH-I997 using xda app-developers app
Okay, so you say you are trying to root your device.. using superoneclick?
You made sure you have usb debugging on? Does the program return any error?
Please I need you to be as detailed as possible to be able to tell what is happening and to be able to give you better assistance.
Edit: agreed, if it is on it should appear right next to the "usb connected" when your phone is connected to a Pc. You double checked it is switched On in settings?
Sent from my sweet and buttery Infuse
I'm not using super one click just adb for temp root usb connected woeks
Sent from my SAMSUNG-SGH-I997 using xda app-developers app
May I ask why you want temp root instead of fully rooting it?
To obtain temp root through adb is a bit complicated and it requires using a series of commands to push our phones exploit and run it from within.

Well that should be because of Usb Debugging not being turned on..
Follow the instructions here and let me know if you succeed. If it does not, tell me what the program returns or if becomes stucked at some point.
It just waits for device. Tried it yesterday

Strange.. Well that leaves us with odin or heimdall..
If after entering download mode neither of them still recognize it, then the problem could be the usb cable or the usb port
Oh I never thought of cables I will get my moms and try. At the fair so will try at home

Didn't work. In download mode the pc says USB device malfunctioned

Bad Bootloader in Nexus S 4G

Hi, I made a bad flash bootloader I put in my Nexus S 4G a Bootloader.img of korean version. Now I'm not root and my USB can't set connection. All things are working less USB and CDMA radio. I can start in fastboot mode and download mode but the usb connection is broken. I tried to follow this thread http://forum.xda-developers.com/showthread.php?t=1566475 but when I opened my nexus s 4G the electronics things was in different side. I made a USB to UART converter and I could see a linux debugger and a state console and sent me a message such as: The bootloader are not ready to start a USB connection. As I have a Android 4.0.4 working now I'm waiting a Jelly Bean Updated to patch a new Bootloader image. What do you recommend me to fix it?

Thanks you very much but I don't have CWM recovery and it can start in fastboot mode but my PC(Windows MAC and Linux) doesn't recognize it when I plug in it. I thing the protocol USB is broken for the bad bootloader for this reason I can't set connection with fastboot or download mode.

[Q] Phone will not boot

Hello,
So I was trying to flash back to stock after a failed attempt with cyanogenmod 10.1, and stupid me accidentally hit the phone button in Odin. Now my phone will start up, show me the "galaxy s3" screen and not do anything after that. Furthermore, my suspicion is that my home button does not work (even though it was working perfectly fine this morning). Because of this, I can't enter into download mode. My phone is effectively bricked. Any help or suggestions?
Randomly got it to go into download mode after hooking it up to the wall charger. Fingers crossed.
Even after this, it still won't boot correctly.

What did you do after you got it into download mode? You're going to need to Odin back to a full stock ROM

I plugged the phone into my computer and chose the correct file under pda. Then once everything seemed ready, I hit start. Odin gave me a "pass" and everything.

If you bend the inside of the port on your phone towards making the small side bigger it works.

Uninstall USB drivers and than plug in the blaze and let your PC recognize it or go to the T-Mobile site and DL the drivers. I've had that happen when I plugged in other phones, most recently when I got my s4. It wouldn't let me open the folders for the blaze. It would flash on than off. Just don't plug the other phone in again after you get the drivers. If it still don't work try regedit and see if its leaving behind traces after the uninstall of the drivers.:good:

Nexus 5 unable to authorize

My friend got a new nexus 5 and for some reason the window that usually pops up to authorize the computer does not show up. Tried different cables, debugging is enabled, tried hard reset, software is updated. My nexus connects and authorizes fine. Inability to authorize is preventing us from being able to flash custom recovery. I was able to boot device into bootloader mode and unlock it though, but no luck when it is booted. Any ideas?

Yes, you know how a window would popup asking to reject or accept when debugging is enabled? That window never comes up. So, apps like nexus root toolking or most adb commands do not work.

You may need to run your pc without antivirus and firewall.. Right click a program and select run as administrator..

Also try switching/toggling modes when you plug the USB cable in

Sounds like you don't have the latest adb&drivers. This happened to me also. Those can undoubtedly be found somewhere on here by searching.

Not just the drivers, use a newer adb too. If that doesn't work you can clear the authorized devices on the phone and there is also a file located on your computer that I think needs to be deleted also.
My nexus was really picky on the debug 'handshake' whereas I had to remove all authorized computers/delete the file on my pc and use the newest adb and drivers - and even then I had to reboot the phone first (once everything was cleared) and use the newest adb & drivers to make it work right.
