[HELP] GNex toolkit v5.6 - ADB problem

[FIXED]
For some reason Toolkit didnt work for me and i used this method to unlock bootloaders and root it.
http://forum.xda-developers.com/showthread.php?t=1362957
Also installed CWM recovery
------------------------------------------------------------------------
I installed my drivers and 1st time when I connected my phone in adb toolkit recognised it and showed his id. Next time when I connected it in adb it didnt recognise it in toolkit but windows recognise my phone and i can access it.
I've rebooted my pc every time and reinstalled couple of drivers:
-Naked samsung drivers
-Pda drivers
-Samsung_USB_Driver_for_Moblie_Phones_v1_4_6_0
Nothing worked.
1st time I used Samsung_USB_Driver_for_Moblie_Phones_v1_4_6_0 and i tried again and nothing.
I am on Windows 7 64bit version.
If anyone knows how to solve this please share the idea.

I was facing lot of driver issues when connecting my GNex for the first time to the laptop on WinXP. Installing the drivers through the GNex Toolkit also did not work for me.
Finally what worked for me was, installing the latest version of Android SDK with the additional package of Google USB drivers, and then manually selecting the drivers after connecting my phone instead of asking Windows to look for drivers automatically.

I had trouble when first connecting my GNex too. However, these drivers worked for me (plus work with many many other android devices):
http://forum.xda-developers.com/showthread.php?t=1379875
If you have several android devices you'll find that you don't have to install multiple drivers for adb, fastboot, etc. for each of the devices.

Taken from post#3 of the ToolKit thread:
Note 1: If the driver doesnt install automatically then double click on the Android 1.0 item, then click on the driver tab and select 'update driver'. Select 'browse my computer' and then 'Let me pick from a list'. If no items appear in the list then untick 'Show compatible hardware' and find the Android adb driver or Samsung adb driver.
Try that as they may be on your pc and just not installing.
Mark.

Got them working now but i have problem when rooting, using GNex toolkit 5.6
It boots into android, i set usb debugging but when the phone is suppose to boot back to fastboot it gives error device not connected.

[Q] Cannot Unlock Bootloader on Windows 8.1

Hello,
I cannot get the bootloader unlock working on my Win 8.1 laptop by any means. If I try through hasoon2000's toolkit, I get the error that the ADB server did not ACK (whatever that means). If I try using the command line and HTC's official method of getting the TokenID, I get a message that a certain ADB-related dll is not installed. I have installed the USB drivers that come with hasoon2000's toolkit about 4 times now. I installed the Android SDK and even Samsung USB drivers. I'm going to uninstall everything, can someone walk me through the step-by-step to get things working? I've read that USB 3.0 is the problem, but I only have USB 3.0 ports on my laptop.

Use another computer if you can.

I had similar problems until I used this version of adb
http://www.mediafire.com/download/e5mieo2vxjd71ws/android-tools.zip
Run everything from the downloaded folder.
First of all ensure you have USB DEBUGGING enabled in DEVELOPER OPTIONS in the phone settings.
Open the downloaded folder then right click inside the folder while holding shift then choose 'Open command Windows here'
Plug in the phone using the original HTC usb cable then in the command window type ADB DEVICES. The response should be a device comprised of letters and numbers.
If you don't see any device attached try swapping the cable to another usb port. If you see your device attached then follow the unlock instructions at HTCDEV as its the most reliable way.
If still no device then it could be a usb driver problem. You should here a ding when you plug your phone in.
Make sure the Unlock_code.bin is in the above folder when unlocking.

That version of ADB didn't work for me either. Anyway I was able to get fastboot to work but not ADB so I was able to unlock and root and everything through a strange method using only fastboot.
Second question, if I am switching between AOSP roms, say for example CM to PA, can I dirty flash or do I have to reset?

ADB does not work with USB 3.0 ports yet on Windows 8 or 8.1. You have to use it on a USB 2.0 port. I have had best results with Windows 7. Fastboot, however, works just fine on 8.1 and 8

Not so, I and others have ADB working fine on USB 3.0 ports.
The problem is Windows 8 driver signing enforcement blocking the install of drivers. You need to go to advanced startup options to disable it.
Download these drivers first and extract: http://www.mediafire.com/download/i3lcm7dwl581518/ADB_Fastboot_Drivers_Win81.zip
Follow these instructions to disable driver signing enforcement: http://www.isunshare.com/windows-8/...gnature-enforcement-in-windows-8-and-8.1.html
Once fully booted go into device manager and you should see a device called 'Android 1.0' with an exclamation mark.
Right click 'Android 1.0' then 'update driver software' then 'Browse my computer for driver software'
Click the 'Browse' button and then browse to the driver folder 'ADB_Fastboot_Drivers_Win81' extracted earlier then click next to install the driver.
You will get a warning about unsigned drivers, just ignore and continue.
The drivers should install and you should see a new entry in device manager called 'Android phone' which means the ADB driver is installed.
ADB should now be working.

Thank you so much for this. Have been wondering for a very long time
Sent from my HTC One_M8 using XDA Free mobile app

It sounds like you've got plenty of technical help already, but I will say that I use ADB perfectly fine on my desktop with Win 8.1 so it's possible. I also use hassoon's toolkit occasionally with no issue.
Before I could get the desktop to recognize the M8 I had to completely uninstall all drivers related to my previous galaxy nexus as well as remove any mention of the device in Window's USBdeview. After a reboot, I just plugged in the M8 and windows automatically installed the necessary M8 drivers. I can then run fastboot and adb from the toolkit.

I ended up uninstalling the MSFT USB 3.0 drivers and use the Intel USB 3.0 drivers instead on my Win8.1 laptop that has only USB 3.0 ports. Works great.

Help GNex has no OS and won't connect to a PC!

Windows 8.1; but had same problem with Windows 7 computer.
USB device not recognized
The last USB device you connected to this computer malfunctioned. And Windows does not recognize it.
Windows has stopped this device because it has reported
problems. (Code 43) A request for the USB device descriptor failed
Tried using WUGS Toolkit to install drivers, not happening.
The phone charges via usb port with no problems
On top of that, daughter wiped phone, there are no ROMS, or usable backups.
I can get into TWRP Recovery, but it can recover what isn't there. Tried factory
reset, still nothing. No matter what I do, I get No OS Installed! Are you
sure you wish to reboot? If I do reboot, just get GOOGLE screen with lock
symbol.
Without being able to get a computer to see the phone, I can't get a ROM to
load.
Maybe change USB port with cable? But I don't want to do that if the problem
is software related.
Any ideas what I can do???

I just went through something similar like this last week, what a pain in the A$$.
Not entirely sure if this will fix your issue, but hopefully it'll help some how.
I ended up having to manually install galaxy nexus driver so I could sideload a ROM since I formatted my internal storage to test out this new F2FS BS... Anyways.
LOL
First you'll need to download and unzip "universal naked driver 0.72" Google it.
Now, without your GN connected open device manager and THEN when you plug in your GN to your PC you should see it pop up in the portable devices section.
AND also under other devices there should be "galaxy nexus" right click on it and click "update driver software"
Click "browse my computer for driver software" select the unzipped universal naked driver folder, click next and click "install this driver software anyway"
Now it should show "Google galaxy nexus ADB interface" in device manager under Samsung Android Phone.
Reboot GN into bootloader
OR
recovery (if you have a ADB supported recovery eg. TWRP 2.7.0.0, and enter ADB mode)
Now there are 2 ways to do flash an Android OS, some may find 1 easier then the other:
download/install "Wug's Nexus Root Toolkit aka NRT v1.8.3.sfx"
Google it.
Run NRT and it'll instruct and guide you through the steps required and whatever is needed to continue, eg. Select device, download TWRP 2.7.0.0...ETC.
Or
Download/install ADB setup 1.3
Google it.
I found this method a little more simpler.
Open the folder you have your ROM/gapps zip files saved on your PC, hold down shift key and right click on the folder, click "Open command window here"
Now in the command window type in "adb sideload XXXXX.zip"
XXXXX = COPY/PASTE the ROM file name. Eg. 20140615PA443RC2.zip
Press enter and now it'll flash the ROM onto your GN.
Repeat the same steps for gapps/kernel zip files.
Reboot your GN and enjoy.
BTW
I'm still loving running ParanoidAndroid Jellybean 4.1.2.

Its like pain in the A** to install phone/adb drivers in win8/8.1
I had a similar issue with my gNex a while ago but i had the drivers installed in my pc so it wasn't that difficult.
Why don't you try to install this toolkit http://forum.xda-developers.com/gal.../gnex-toolkit-v11-1-0-drivers-backup-t1392310
When you run the toolkit, it may ask you to select your device, build number etc and also about installing device drivers.
Install the drivers through it and then connect the device in recovery (twrp) mode.
it should detect it and then you can push files/roms to sdcard (internalMemory) using adb push or the built in options in the toolkit.
then flash the rom and you're done
and i recommend using win7 or xp or vista for doing this because the driver installation in win8/8.1 is a bit difficult compared with other previous windows versions but there is still a way to install drivers in win8/8.1 its just a lengthy process
All the best :good:

OK, downloaded universal naked driver 0.72, connected gnex, but it only shows up under Universal Serial Bus controllers as Unknown USB Device (Device Descriptor Request Failed), not under Portable Devices, and will not allow install of of universal naked drivers, & yes I have toggled to allow win 8.1 to installed unsigned drivers. Since I cannot get phone to turn on to full android, it is not recognized. Any other suggestions?

You have to go to the device manager, double click on the "unknown usb..."
a dialog box may appear and then click on the 'driver' tab.
There u may find update/install driver button.
click on it and another window may open.
then select browse my computer for driver software and go to the respective folder where the drivers are.
then click next and it may install the drivers.
if you have installed the toolkit then you may find a folder in the toolkit's installation folder which has drivers in it.go through it if you want :good:

[Q] My 8.4 wifi can't connect to windows 7 pc

I have recently root my samsung tab pro 8.4 wifi version. Everything seems to work well, except USB connection to my windows7 desktop. I installed the latest version of Samsung usb driver (download from Samsung's web site for my device). Whenever I connect it, media device mode, the "installing device driver software" icon spins for couple of minutes, then I got the error of "Device driver software was not successfully installed" . In the detail dialog window, it says "MTP USB Device" failed with a red cross. what did I do wrong? thanks.

I have tried several different USB 2 ports on my computers. Also I have Developer mode turned on, with or w/o USB debugging checked. Nothing seems to work. Also the camera mode doesn't work either.

Did you install kies 3 from samsung?, this should install all the drivers you need.
http://www.samsung.com/us/kies/

I tried with this version of kies from samsung's website, not working. Got the same failed to install device driver message.
In windows device mananger, it shows a MTP USB device with yellow "!" mark on it. If I try to update driver from here with the driver installed on my computer, it says I have the latest driver installed already.

Try going to Device Manager in Windows, find the device, pick the option to select from the drivers on the computer, then pick the "USB MTP drivers" (generic, not Samsung) and see if that helps.

I see two drivers, however either works for my 8.4 pad. It says "This device cannot start (code 10)"
Also when I open the properties for this device in device manager, it shows its driver running is from Microsoft, driver version 6.1.7600.16385. Should be a driver from Samsung?

Are you running stock TouchWiz ROM? Just to be sure.
Otherwise you could remove all your USB drivers related to Android and start from scratch with just the Sammy driver. I had to do that for my previous OnePlus One, it just wouldn't connect. It chose a wrong driver each time I hooked it up so I had to just remove those from the driver store and then make it choose another one. That was for ADB thought, but I guess it couldn't hurt to try anyways.
The reason I'm mentioning if you're on stock ROM is because this morning, on CM nightly 01-24 I had some troubles with my tablet being read by Windows, it was fixed in 26 so.. Just wanted to mention it.

Yes, I am on the stock TouchWiz ROM, but I rooted it following steps from one thread in this forum. Before rooting, I was able to connect. I do have a LG G3 phone connecting to the same computer successfully. Will this cause any problem? Will going to CM ROM solve my problem?
Also, can you tell me steps to remove all my USB drivers related to Android in Windows 7?

It may work to install CM11 or CM12, BUT try this toolfirst (uploaded to my personal box account) Find all your mobile device drivers in this list and mark them and go to "File" and click "Uninstall marked drivers", restart your PC and plug in your tablet. Then try plugging in LG after so it gets drivers later. I'm not sure if it will work. But it should apply new drivers. If it doesn't work, uninstall the drivers one more time and download the Samsung drivers from 3rd party and install them and apply then manually to your tablet through Device Manager in Windows.

Its always a possibility. I'd try to uninstall the LG drivers. You can always re-install later (if needed).
In a perfect world, the Sammy drivers would be what you want. But this is of course not a perfect world. I've had better luck using the "generic" Microsoft MTP USB drivers over the HTC drivers on my HTC devices.

Just before I about to give it up, it connects to my another computer now, which is my main computer and it had trouble connecting to. All I did was restart my pad several time and odin twrp recovery to it. It connects after rebooting. No idea what cause this problem, but it works now. thank you for all your help.

Glad you sorted it out, to some degree or other.
USB connectivity on Android devices is very tricky, at least on Windows (can't speak on other OSes). My HTC phone connects fine to my work laptop with the HTC drivers. On my home computer (also Win7) it frequently drops adb connection and I have to manually select the "generic" Microsoft drivers to make it work (and the HTC drivers never seemed to work completely right either). My Sammy Pro 8.4 seems to connect just fine to my home PC, however. So it seems its just a crap shoot what kind of connectivity you will get, really.

MTP is not working after connecting to PC

Once I installed the USB Mass Storage enabler zip on stock Lollipop, now whatever rom I flash (be it stock or custom), MTP is not working, though the PC detects the phone when it is connected through the usb.

Thanks for your reply, but drivers are already installed.
When I'm connecting to a different laptop running Windows 10 (where drivers are not installed), there the MTP is working normally.
But not in my laptop running Windows 7.

Uninstall the drivers on the laptop with Win 7 and reboot the laptop, thereafter reinstall the drivers using the tool stated above for MTP . Occasionally the drivers are not installed duly (i.e. Device manager may not indicate the exclamation (We may presume the drivers are appropriately loaded,when in fact the contrary usually occurs) mark or error for the driver) but the transfer of data will be precluded.
Uninstall and reinstall the drivers for Win 7 laptop for resolution.
Thank you
