Use Linux or repair your drivers or try it with enabled USB debugging.

[Q] Root Problem Xperia T 9.1.A.1.1.140

Hello XDA members.
I tried to root my Xperia T with the method of Bin4ry v30
After choosing Method 3 it just shows daemon started successfully and then nothing happens.
Also I tried to uninstall PC Companion and install it again.....by device Manager I can't find any specific drivers but I know they're installed since my Phone is working on MTP.
Any ideas what should I do?

i know the answer is certainly "yes", but first things first;
have you enabled USB DEBUGGING in Developer Options?

[Q] Rooting w/o USB connection

Hi, guys! I have a really big problem :/. Right now I'm using the stock 2.3.4 gingerbread from LG ,but you all know that this is the worst OS ever. I wanted to get rid of it but i cant connect my device to the computer. It's only charging. I need a way to root it w/o usb connection. Do u have any suggestions? It's not a software problem! Something inside the phone is broken and i don't know what it is. Is there a way to root it via bluetooth or SD card? I didn't find any apps to root it too. I know gingerbreak etc, but they dont work for 2.3.4. Thank you in advance and i hope there is a solution. :fingers-crossed:
I am afraid you can't. Replacing your micro usb port could solve your problem. I reccomend to buy a micro usb port which is already on the flexible cable so you can avoid ironing.
Sent from my LG-P990 using xda app-developers app
So i'll need this? I asked a staff member in a service station and he said that the port isnt broken. So i need the whole thing port+flexible cable? Is that what i should do? Thanks alot. Ohh man i cant post links still: http:___//i.ebayimg.com/t/LG-G2X-Optimus-2X-P990-P999-Micro-USB-Charging-Port-Flex-Cable-Repair-Part-/00/s/OTU1WDE0MDI=/z/unUAAOxy9DRSAoTf/$T2eC16R,!wsE9suwycosBS!oTe7+VQ~~60_57.JPG
stupid question: did you try another usb cable or usb port?
Yeah, dude. Of course. I've tried different settings like usb debugging on/off too but still nothing.
here are some articles you might want to check out regarding usb connection

i forgot how the mass storage settings in gingerbread look like but there should be an option to put the phone in "charge only" mode (which you should disable)... pressing menu key in settings > storage doesn't give you any options to choose?
In gingerbread you can only turn usb mass storage and usb debugging on/off. These settings didn't help. I'll read more about the first link you gave me and try it out.

This is quite challenge, root without usb connection. First idea I got to use ADB over WiFi, but this is available from ICS, not on GB.
Second idea - what I remember, some of root methods use APK installation over ADB by script. Maybe you can search for these script methods and place all required files on SD Card. Then try to execute commands by terminal on device itself to install and root.
It's just my idea, maybe wrong, maybe help.

Yes that is what you need if you have to replace your USB port but you don't have skills to replace only the usb port.
You can try gingerbreak to root your phone, but it maybe won't work.

I'm not aware of ADB and scripting. Can you give me sоme guidelines?(I'm sorry 'bout my english. I hope you understand)
p.s. I found some info about ADB. So you need ADB to control your device via commands, but you can use ADB on your computer? You say that i have to find a way to use ADB on my phone so it controls itself and roots?

sorry to hear about your problems but just a simple question here have u tried another computer ? i had this problem with my nexus when i connect it to the pc i couldn't transfer my stuff to it but adb worked, but when i took it to another computer both mtp and adb worked
Yes, I've tried another pc's port and it didnt find my device too. My issue isn't the same i mean that my computer doesn' recognize the phone. There are no messeges that appear on the device or computer.

Guys, the problem is not in the computer nor in the cable, it's in the phone. I'm 99% sure that it's a hardware problem. So i need to find a way to root or flash it without using usb connection.
i'm somehow sure that the real problem here is the device driver installation on your PC/Windows, not the phone...
btw which windows version are you using?
did you try checking out the AIO tool thread?

if you read the 1st post, you might find out how could it help you... especially if you use win 8 which caused problems for many other users when trying to install the drivers or trying to flash the phone...
I - Install APX (NVFlash Recovery) Drivers if not already installed.
It starts the windows device driver wizard to help you install the drivers needed for NVFlash. It detects your system OS and gives additional on-screen instructions needed if your PC is running Windows 8.
FYI: The drivers are located under ToolKitFiles\nvflash\driver folder.

I use windows 8 from a week. Anything i've done before was on a xp/ win 7. The problem isnt in the win 8 i use now. I've tried everything on my xp laptop. I have a friend who has the same phone and he can connect it to his computer so everything is fine with his computer. I've tried to connect my optimus to his computer and again it wasnt found by the computer. The problem must be in my device.
I'll try installing the APX drivers.

when you say a statement like "I cannot connect my phone to my PC" that really isn't saying much. but let's say you mean that your phone isn't being recognized as connected, plugged in as unknown device at all.
First thing you need to do is figure out who the culprit is, is it your android phone or your windows PC. Easy check: try plugging in your phone in another PC. at the very least it should pop up as a connected unknown device, or as your moto model number. if one PC doesn't show it try as many as you have access to.
You can also try plugging in other devices in your original windows PC and see if they're recognized.
so there are a few scenarios but I'll pick one scenario where your phone connects to the other PCs and your computer recognizes other devices. in this case (or even in most cases) I'd suspect a problem or conflict in the device manager of your PC. plug in your phone and go into control panel, device manager and look through it, look at the USB connections, look for any yellow error triangles, and if you notice something fishy uninstall the device and unplug and replug your phone.
keep trying at the end of the day you're the only one with physical access to your hardware so you're the one in the best position to troubleshoot it.
was doing it as a quick suggestion... as the previous posts says, u didn't tell us much info... we don't know what you've done, nor tried...

LCD broke and USB debugging off

I need help with this desperately, so please bear with me.
For some reason my USB debugging was turned off. I dropped my phone about a foot onto wood floor with a case and the LCD broke. Phone still works as I'm getting notifications and connects to my PC.
Won't show the files because USB debugging is off.
Pretty sure I can't get a cable and hook it up to my TV because its not supported without rooting or without downloading an app which I cannot do, obviously.
So am I done for or is there a way to help me?
I saw somethings here and there but nothing was really detailed or what to do if USB debugging was not enabled.
Please help me!
Thanks.
EDIT: I have not tried recovery mode yet because the phone still has a charge and I'm not sure if that will work anyway

There is no LCD on this phone
So what are you trying to do? Get the files off your phone? Please can you answer the questions below?
- Is the bootloader unlocked?
- Is the device encrypted?
- Does the device have a screen lock?
Device is working properly and it does not have a screen lock.
I just need to access the file that are on the phone

Not sure about the other 2. It's a stock Nexus 6.
When I plug the phone into the computer it says 'no files' which is because usb debugging is off.
So how would I be able to get the files off the phone?
If its on marshmallow, it will be because the default menu option is USB for charging not MTP transfer.
Have you got twrp? Could try and mount the partition for data, not sure if its possible without a working screen though!

No, you need USB debugging for everything except browsing the files, but as mentioned on Marshmallow when you plug a device in, there is a notification you have to select to allow you to set it to allow that.
If touch works, you might be able to do it, with some guidence / screenshots from Marshmallow userrs.
