Unable to conect my tab to pc with legit asus cable.

Ics says nothing. JB says it charging lol.
With my usb data. It was connected succefully before. So i am clue less

Are you trying to connect to transfer files, sync outlook or issue ADB or APX commands?
Does your computer play the new hardware sound?
What OS is your computer running?
Do you have USB Debugging checked?
Have you tried another USB port on your computer?
Also, many of the JB ROMs show a charging indicator via USB even if it is not really charging.

APX commands
No
OS: Windows 7 64 bit.
Yes, I haave checked
I have .... 9 usb ports. None of them works.
I did use other and it didnt work.
I will test on other pc's.

Are you sure you are getting it booted up into APX mode? I know it is a bit tricky to do.

[Q] No ROM, can't adb sideload!

So I wiped my phone, went to flash the unofficial kitkat CM rom, and found out I had the wrong recovery version. No biggie, I thought, I'll just reflash my backup ROM. Well, it wasn't where I left it, so now I'm stuck without a ROM to flash. That was okay, though, I could just push one via adb. Then my computer gave me the "USB device not recognized" thing, and so I've tried reinstalling drivers, cleaning the registry, rebooting many times, and all to no avail. I'm lost! Wise ones of XDA, what can I do?

Bump. I really could use some help, I use my phone for work and school and it's a paperweight in it's current state.

I'm guessing you have no access to an sdcard? Looks like you need to use Odin to go back to stock then reroot and unlock. Try uninstalling the drivers then boot your S3 into download mode (hold volume down, home, and power) follow the on-screen prompt, then plug your S3 into the computer to force install new drivers. Now, unplug and pull the battery and try flashing stock, and root/unlock. Try another port, keep the computer plugged into the wall, and also make sure you're using the Samsung USB cable.

No sd card. My computer shows the same "USB device not recognized" message while the phone is in either download mode or recovery, and while using my samsung usb cable and a new one I bought yesterday evening. I've deleted every driver for it, tried every port, and it's the same thing every time. EXCEPT, for some reason, when I plug it into my USB 3.0 ports, it shows up in device manager under "other devices- unknown device", but when it's plugged into my USB 2.0 port, it shows up under "USB controllers- unknown USB device (invalid device descriptor)".

If its not connecting to your main computer, try another computer. Honestly though, I think you need to purchase a cheap sdcard (format it to Fat32) and put a rom on there. Cuz you can still access download mode and also recovery correct? Maybe by then, there will be a few more replies or some idea that will get you in the right direction.

I just have my laptop. I've bought an sd card now, but I don't have a reader. When I fix this I'll put a backup on there I think I'm just going to reinstall windows and get a fresh start. Then maybe I'll be able to ADB sideload a rom.

I had similar problem
After I screwed up my device, this was the way I got the right recovery installed in order to flash 4.4
I cant post links in posts yet, I'll pm you the link.

[Q] My PC can't see my TF300T....any ideas?

Hello
I am slowly trying to learn how to root my TF300T in preparation for installing my first mod but I have a problem. I am using Android 4.2.1 and as far as I can tell I have USB debugging ticked on my settings.
I am following the Cyanogen tutorial and I have installed Android SDK to my PC and put it into the root of the C\ folder. It is revision 22.3, if that helps anybody.
I do not know if I have the correct settings within the Android SDK Manager, however the Google USB Driver says that it is installed.
However when I connect my TF300T to my PC, with a 'male to male' USB cable nothing happens.
If I connect any USB device to the TF300T, then it is recognise and I can use it.
If I connect my Nexus 4 phone to my PC then the PC recognises the device in both the Device Manager and a Auto-Play pop-up menu comes on the screen. I can then freely move files to and feom the phone to my PC with no issues.
Does anybody know where I am going wrong with either my Tablet or PC which is stopping them communicating with each other?

bump
Anybody able to help me?
please.

Not sure, where you are connecting that cable.
You need to use the USB/charger cable that came with your device and connect that to your PC.

Thank you so much for helping me with which cable I should use. I thought I was going mad.
Using the USB/Charger cable worked.
When I connected my Tablet to the computer, my PC went looking for the drivers. The PC found most of them however I got the following error message
ASUS Android composite ADB Interface No Driver found.
Any ideas how I find and install this ADB Interface?

Sorry, I am a Linux user, never had any USB driver issues myself. If you search the forums for "USB naked drivers", you should find some help and instructions.

Sadly I do not have a clue how to use this bit of software. I have installed it. My Tablet is connected to my PC.
But I do not have a clue what to do from there.

Root without PC/USB

Hi,
Have a TF101 tablet here stock rom, stock recovery...
However it seems the USB will not detect on a windows PC tried multiple cables multiple PC's tried from recovery nothing is detected in device manager at all. Tablet doesn't even detect that its connected to PC either.
Is there anyway to root this thing without USB??? I need to root it so I can install recovery and flash another rom.
Thanks,

Which Windows version are you running?
If you use Win 7 and prior you should be able to connect with the universal naked drivers manually installed from device manager
Win 8 and above need driver signing disabled or they wont install the driver and the PC wont see the TF
If you have already tried the above, you might need a new cable

Thanks. Well i tried windows 7 x64 and windows 8 x64, neither showed any device or unknown device in device manager... Tried multiple cables as wel, no dice...
Shouldn't MTP work regardless of drivers installed in windows 7/8 ?

Are you putting the TF into APX mode?
Connect TF to PC USB > Power Off TF > Hold Power & Volume Up until the PC recognises it (Only takes a couple seconds, nothing appears on the TF screen) then install drivers
You need APX mode for Easyflasher
For normal media transfer, it will still need to install at least some USB type driver, as do all USB devices to function, possibly not the APX drivers
Check in Developer Options > USB Debugging mode
Try it enabled and disabled with the TF plugged in
But really the MTP drivers are not what you need if you want to root. you need APX mode to work (As above)

Doesn't seem to do anything when I hold power vol+, the screen of the tablet (blank/off) and on the pc nothing is being detected.
I can get to the bootloader/recovery via holding power vol- though. Also tried USB debugging mode... nothing is detected whatsoever... ordering another cable on ebay will see if that works but I doubt it since it seems to be a common issue with this tablet (port not working with pc)

I edited my post
Nothing will appear on the TF screen in APX mode until data transfer begins
The cheap non genuine cables are renowned for data connection failing, genuine cables are recommended
I still have my original cable and it still works 100%

Using the original cable, I still can't tell if its in APX mode, installed all the drivers provided by asus, nothing is detected in windows device manager. I'm 100% its not being detected ie. no connection. I ran easyflasher anyway both sbk1 and sbk2 says it flashed recovery but it never did still the stock recovery is on the tablet.
Will try again once the new cable comes in, thanks.

Forget the ASUS drivers, use the Universal ones from the Easyflasher thread
Here's what will happen when its working as intended
When you plug the TF into the PC, no matter what mode it is in, the PC should sound the USB connect sound
When you power off the TF, then put it in APX mode, the PC will again sound the USB connect noise, then it will fail to install the correct drivers
That's when you open Device Manager, find the ! missing driver ! exclamation mark, and update drivers manually pointing it to the extracted Universal drivers
Once you have installed them, then Easyflasher should work as normal
So unless you actually have a hardware fault on the TF, or the USB ports of the PC, Id hedge my bets on the cable
Have you tried a different PC?

Ok, well ya thats the thing no sound or detection of anything when plugging it in, or going into apx mode, rebooting etc...
I tried 2 cables and 2 different PCs. Will try a new cable but I betting that is won't work either... we'll see.
Thanks again

No need to bother with cables and drivers, just download Baidu Root: https://app.box.com/s/pyehf9fh4xem3hy50dot
EDIT: The app has built-in su access management, but I'd recommend installing SuperSU from the Play Store.

Lenovo A850 No usb option

Hi xda, I need some help here on my lenovo A850.
Whenever I plugged it to my pc, it don't pop up any usb connection option and my pc didn't even detect it.
I can't use flashtool since pc didn't detect my phone.
What should I do?
I've rooted it using framaroot and installed cwm using mtk uncle.
Should I just try and flash other rom via cwm?
Really appreciate any help from anyone here.
Have a nice day.

Do you hear the windows sounds of connecting / disconnecting devices? If not, your cable must not working...
Else, try installing the USB drivers from here.
You can install roms from CWM BUT if anything goes wrong, flash tool can almost always fix it.
So i advice you, before installing anything make sure that your phone can connect to flash tool.

Do not expect to connect to flashtool if it doesn't connect to your PC.
From what you are saying it seems to me that the cable or the phone or the USB port has problem.
Try these: (until you hear a windows sound or see the phone charging)
- Try an other USB port
- Try on an other PC
- Try an other cable
- Try mounting from Recovery?
You can also try installing the USB drivers from the link i gave you in my previous post...
