[Q] Need help rooting... adb devices = nothing

So I cracked my lcd and just received a replacement from insurance... it wont show a device so I can root it.
What's is there to check in order for the device to show? I have reinstalled the HTC drivers and restarted my system but nothing.
What is the best way to root 2.3.3?
Thanks!

Check usb debugging on under settings -application- development and then try adb

already checked... i found this on another site, but am not sure what "Disk Mode" is
I type “adb devices” and get no serial number!
That means your drivers aren’t installed correctly or your phone isn’t in Disk Mode or USB debugging is not check on, please check those three and you should be good to go!

When you connect to the computer, you should see the usb icon in the status bar. Make sure it says charge only for adb to work. Might also want to download HTC sync or get the android usb drivers from unrevoked.

used another computer... everything is great now
must be a driver issue on my laptop
thanks for the help though!

Re-install the sdk, and make sure you have the two adb.dll files, as sometimes they are missing, and cause it not to work.

[Q] ADB works, but no MTP/PTP functionality

So I got my Nexus 7 2013 to work perfectly on my laptop, which runs Windows 7 x64. However, on my desktop, which also runs Win7 x64, I only have the ADB working correctly for the N7. As I recall, sometimes there is a device under Device Manager called "D:/", which is non-descriptive, but seems like the closest thing to the N7. I have tried to update this mysterious device's drivers by pointing to Google's USB drivers and the OEM drivers, but neither was accepted. There are also no devices with missing drivers listed in Device Manager.
At this point, I am not sure how to proceed. Is there a precise way identify under what device name/category the N7 shows up in Device Manager? Please advise. :fingers-crossed:

See if this helps:

Make sure USB Debugging is disabled, device is plugged in, and go to device manager in windows. Then right click on nexus 7 or android adb device, or any similar name. Then after uninstalling everything, unplug device and replug it in. Let windows get the drivers, and MTP should work!

Deleted everything related to google and nexus. Still installs as adb device but doesnt show as nexus 7 device! Wug fresh has this program in its tool kit

It might sound dumb, but I was literally just having this issue. But apparently certan roms or kernel disable MTP mode when they are installed. i reinstall every driver just now. My fix was as easy as going to Settings > Storage > Menu Button Top right > Enable MTP box.

Going to try a custom rom see if that works!

I have tried a number of the suggestions in this thread, including the deletion of all my google/adb/nexus (and samsung) drivers. None of these steps resolved my problem. However, at the end of the day, I can still use both ADB and MTP, just not at the same time. So it's not a big deal. I think I will mess around with Tasker and/or get a widget for turning ADB on/off.

Are you ale to get a nexus 7 device to show so you can access internal storage? I can only access camera storage.

Are you running stock?
If so, do you have USB debugging turned on?
If you have USB debugging turned on, the USB IDs change and it might not (depending on what you have previously installed) recognize the MTP device anymore.
If you turn off USB debugging, it should recognize MTP.
Now if you are on a custom ROM, there might be some issues on the ROM side causing the MTP problem. Try going back to stock and see if it works.
If you are on stock and have the case where MTP only works with USB debugging disabled, then you can try this driver inf I put together to address that.

[Q] Device undetected by Windows.

After going through a replacement process (twice) after cracking the screen on my first device, I was relieved to find that the replacement I got sent wasn't updated to un-moddable status. However, after using rumrunner to s-off, flashing cwm 6.0.4.8 recovery, and using that to install cm11 m6 snapshot, I was disappointed to find that my phone will not connect to Windows in a manner where I can access USB storage. Enabling debugging in dev options does initiate the "device plugin sound" from Windows, but after looking in device manager, all that shows up there is "Android ADB Interface". When debugging is disabled, Windows makes no sounds, and there is nothing in the device manager. The only response i'm receiving is that the charge light on the device comes on. I would try to install drivers, but seeing as the computer doesn't even recognize that a device is plugged in, i'm pretty much halted on that front. Any comments or solutions would be greatly appreciated.
Cheers!

Unfortunately, as the computer doesn't even react at all when I plug in the device, I can't manipulate drivers at all. That means no uninstalling or installing :/

once the windows sees the phone. feel free to remove the sync portion of the install and keep the driver installer on the pc.

[Q] Unable to connect M9 to Windows PC

Got a weird one - got the M9, able to connect it at work and on a laptop but not the computer I've got ADB and everything on.
Phone simply does not recognize as a USB drive, I get that it's looking for "Android phone" but it never shows as a device. (MTP, ADB, etc) Suggesting where the HTC drivers I just downloaded results in me getting that they're not what it's looking for.
This is a computer that has worked for my EVO 4G, 3D, 4G LTE, One m7, m8 along with being fine with a host of other devices.
I've uninstalled and reinstalled everything I know to do but no ADB, no MTP. Not a recognizable device to windows other than being "Android Phone" with no drivers findable.
Some things I've done:
Installed HTC Sync
Deleted HTC Sync
installed HTC drivers pack
removed
Bang head on keyboard
Plug into different USB ports
Change cable
Just one computer, the one that I've used with no problem for ages, wants to be a punk

Have you tried enabling USB debugging?
-settings
-about
-software information
-more
-tap build number 7 times
Then go back to settings and enter developer options and check USB debugging

Yup. I just get "Android Phone" as an unrecognized device. I've also set to Disk Drive, MTP, debugging on and off.
Just plugged in the M8, same issue... so it's something that's not M9 specific...

Well that's as far as my expertise goes haha.

Was this resolved? Having this same issue...

It looks like you are just trying to get ADB?
* Make sure USB debugging is enabled (I know you said it is).
* Make sure your computer is not blacklisted on your phone from making connections to ADB.
* Make sure any htc sync or driver package is totally removed.
* Make sure your keyboard still works enough after the head banging. You will only need a mouse, enter, space, a, b, c, d, e, i, s and v to complete the following; but more is always better just in case you need an h or something.
Look in Device Manager. Is it an unknown device (is there a yellow exclamation mark or something next to it)?
Try deleting the driver that it's using - like actually choose to delete the driver software from your machine, not just remove the device.
Once you're totally clean and the phone shows up with a yellow !, try update driver -> let me choose -> have disk -> your android sdk's extras/google-usb-driver .inf.
Pick one of the ADB ones, not sure if it'll be composite or the other one, then test with
Code:
adb devices
in your cmd window.
If it shows up, cool. If not try the other ADB usb driver from the inf...

Thanks. I tried this and nothing helped. Finding the device from ADB devices isn't the issue. It is that the SD card does not show up in Windows Explorer. Other than taking the SD card out and using a micro SD card adapter for my PC, I cannot transfer files via USB. See attached image. The MTP is the issue. Why doesn't HTC Sync/Drivers from HTC.com fix this? -_-;

Oh, I'm sorry I misunderstood your need. Well if adb works yes can always push/pull... Which version of Windows are you on? Is it possibly a 32/64 bit driver issue? I'm reaching here, HTC sync should cure whatever ails you... I hate MTP.

I' having the same issue. M9 not recognized as an MTP device on Win 10 64 bit. Running CM 12.1. Adb works, and the device shows up in Device Manager as "MTP USB Device" under "Portable Devices" section. Right clicking gives only propertied and scan for h/w change option, there is no option to update device driver. Phone shows up as HTC M9 under "Unspecified" category in "Devices and Printers".
My Lg G2 runs CM12.1 as well and works fine as mtp device. (Adb works too). I have been trying everything to get M9 working, but failed.
EDIT
Solved the issue trying random things! The issue was the xposed module "Xposed Media Scanner Optimizer" which was preventing MTP mode by not allowing media scanner to run.

I do not have that module installed, so that can't be what is keeping Windows from noticing my phone as a storage device.
Also, if i hadn't mentioned it before, I am able to see my device with adb devices in the command prompt.

Most likely it is a driver conflict or missing drivers. Uninstall all portable device drivers and start again.

Something to try. Connect your phone to the PC, then go into device manager and look for portable devices. The phone should be listed there and most likely you will see a yellow triangle on it. Click on it and choose to uninstall. After it uninstalls, unplug the phone from the PC and then plug it back in. Allow it to fully re-install before doing anything.

Nope. I've played with device manager for over an hour at a time. Windows doesn't like m9.

Well, my understanding is that the driver used for mtp for Android devices is the same driver that is used for Windows Media Player. When you connect your phone to the PC and open Windows Media Player, is the phone listed there? If not, then you may have something interfering with media scanner. Have you tried starting the M9 in safe mode and then connecting to the PC?

Weird. You must bring it to store to fix

How to make this working again???

The PC connection mode on your phone is set to "Charge only". Idk about the stock ROM, but on CyanogenMod you just press the notification that shows up when you connect the phone to change the mode

Dear wasiq224,
Thanks for your answer, but is not working. I'm on CyanogenMod - but there is no notification shown up. Phone is quite and also PC - no message.
Even if I press under "STORAGE" -> "USB computer connection" the phone is saying: "USB is now disconnected". I checked already various menues for some settings without result. Google was also not help in this matter.

Try going to Developer Options>Disable USB Debugging, then reboot. Then connect your phone and try going to USB computer connection again, and enable whatever connection mode you want. You can re-enable USB debugging after that.

Dear wasip224
Checked once more the debugging setting's. But if the phone is connected to the computer or not connected, disableing USB Debugging is not possible. This item is greyed out all the time. See attached pictures.

I'm at work now, but you use Explorer and go to the folder where you extracted the drivers and use right-click --> properties in one of the files there. There is a tab that lists certificates. Just to be sure you can temporally disable driver signing verification.

Doesn't work for me, it says it cannot find the files. In my win10 install i have two problems, ADB only works if i disable driver signing verification and MTP doesn't work. I tried running sfc /scannow and it says WinUSB is corrupt and cannot be repaired (probably why MTP does not work). I tried using intel drivers for both and it does not work. Only ASUS works (but fails because of certificate) for ADB Composite Device, but mtp doesn't work anyway.

This tutorial could help you anyway.

Hi Kras and thank for the response!
I Tried it too but in my device manager it wont show any device related to asus nor adb.
Tryied to boot into TWRP but no MTP either.
I Tried USDBview but doesnt show. The strange fact is that the phone charges normally.
It happened after i switched to CHARGE ONLY... after that, could never go back "/

I think i´ll try to revert EVERYTHING to stock. Somethings not right.

Another information, the cellphone charges, i´ve tryied to unistall and reinstall every adb usb_driver but in driver manager, nothing appears, even an exclamation. Tried to force install drivers, nothing either. All this happened after set CHARGE MODE i´m so pissed off and frustrated

This is a shot in the dark, but in device manager you can click View>Show hidden devices.
From there you can truly uninstall all drivers, and then reboot and try reinstalling. Maybe this will help.
Also, different ports, different cables?
If it's just for file transfers have you also tried something like AirDroid or Dropbox/Google Drive/Mega?
