Adb device connection - phone looping when usb debugging - LG Optimus 4X HD

Hello.
Sorry for my English first of all.
I have JB 4.1.2 v20b EUR.
I have already rooted this phone, so I wanted to go ahead and unlock the bootloader but I am doing something wrong probably,
because when checking by the command "adb devices" the list is empty.
Already I have done:
1. Installed in my PC - LG PC suite.
2. I think I installed some drivers - adb, fastboot etc. - from here
3. On phone i turned on usb debbuging.
The problem is - when in settings on my phone -> Connection to PC -> Type of connection (IDK how it's called in Your language but I will translate it as: ) LG Software is choosen, and after connecting to PC,
phone starts to loop on connecting as usb debugging and as to Software LG...
What I have done/doing wrong?
P.s. Later I will upload some pictures and vid.

Maybe you should comnect as a MTP device. If this doesn't work go into the startmenu on your computer -> right click on computer -> manage -> device manager on the left side. If there are any devices marked with a yellow triangle it is a driver problem.

you have to make sure USB debugging is on inside Settings | Applications | Development
Edit: hehehe ^^^ what he said.
Go to Settings > Applications > Development > USB Debugging (check)

its that my pc isnt detecting my g1. it says no device detected. PLEASE HELP.
idk maybe I need a way to usb debug without activating?

If you have Windows Vista or 7 you can right click my comptuer > Manage > Device Manager (or just call up device manager in xp) and look for ADB Interface.
Right Click HTC Dream Composite ADB Interface and click Uninstall.
Unplug and replug the USB and it should re-detect.
nevermind me =)
Same problems
I am having the same problems as "samrozzi".
Phone is OK with Reboot command.
Will not recognize "Setprop Persist etc".
My device manager shows (HTC Android Phone USB Device) in "Disk Drives" but nothing about ADB interface.
Also you guys are saying
"Go to Settings > Applications > Development > USB Debugging (check)
Settings where? On the phone? not possible without getting past the registration screen.
In SDK ?
In ADB ?
On Computer somewhere ?
I have un-installed the driver for the phone. I reconnect and turn the phone on. The computer says HTC Google phone--hardware is installed and ready to use. Then it goes away and doesn't seem to be of any further use.
Please help, my brain is starting to sizzle from info-overload.

did you install the driver
USBDeview
Try this:
- get USBDeview : http://www.nirsoft.net/utils/usb_devices_view.html
- unplug phone from PC
- in USBDeview delete all drivers that have anything to do with HTC
- plug phone in PC; drivers should now install correctly IF you have downloaded and installed them before
If the above procedure does not work reinstall drivers (from SDK) and start all over.

G1 Debug Mode

Hi Guys,
I just rooted my T-Mobile Unlocked G1.
After doing this I updates it with Jesusfrek 1.5 ADP.
I want to start learning to create Android application so I was trying to connect the G1 in USB Debug mode.
When the option is selected and connected to usb it does not recognise any new hardware.
On mounting I can view files in the memory card.
Without mounting also I can see Disk Drive>HTC Andoid Phone USB Device
I want to use the device to test my application.
Please help.
Please note: I have bought an unlocked G1 and not the Dev Phone.
Thanks,
Chinmay
Hey Got the problem Solved :
Problem - G1 Not detecting in Debug Mode / ADB Mode
Reason - Windows Automatic Driver Update for USB Disk.
Solution:
Edit the registry
Disclaimer: be careful what you do in regedit.
If you're not sure,don't use it
- Open the Registry Editor (Start > search/run > regedit)
- You *may* need to be administrator to do that
- Search for "vid_0bb4&pid_0c02" in keys or values. It makes take a
while. If you find in a value, delete the whole key folder.
- Some keys might be "locked": right-click them and add "everyone:
full control" to the permissions. Then delete the key folder.
- Repeat the search till no more instances are found.
- Close regedit.
Now the devices will ask for driver and locate the android-sdk\usb_driver\x86
There the phone is now in ADB Mode.

so are you saying if u put it in USB mode it disconnects and not be able to detect it as new device? if its not disconnecting, then its working fine... and go ahead and use adb mode
1st, do you have the SDK and drivers installed on your computer. 2nd, do you know what ADB is?
Start asking your questions in the right sub-forum (Q&A) (Theme) or even in (General), or i will be forced to ban you for 3 days or till you learn.
Thanks

Hi,
Yes I have the SDK Installed and the Environment variables set.
I dont have the Dev phone but I have the dev phone firmware updated on my T-Mobile G1.
Does it require a different cable.
I need to get the phone in debug mode so I can start testing my applications on the phone. Testing the app on the phone is netime better then the emulator.
You missed the 2nd part of question 1 and you didn't answer question 2.
Does 'adb devices' show anything?

ADB shows no devices connected.
When I read the instruction on getting the G1 on Debug mode. It said that when you connect a new hardware would be detected then install the new hardware with the usb drivers in the SDK Tools. - this never happenes when I connect my phone. It does not detect as a new hardware
I can see removable disk in My Computer - if I try to access it says please insert disk. Files are not accessible without mounting the SD Card.
Instead of the Removable Disk being detected the phone should be detected in debug mode right ?
Have you turned on USB debugging in Settings>Applications>Development?

[Q] USB Mass Storage Device driver failed

Bought a LG P970 Optimus Black.
Installed LGMobile Support Tool into my
Windows 7 64bit.
Installed the LG 3.2.1 drivers using LGMobile Support Tool.
Then, I connected the phone to the computer.
Result of drivers installation:
LGE Android Platform Composite USB Device - Ready to use
LGE Android Platform USB Modem - Failed
LGE Mass Storage Device - Failed
LGE Android Platform USB GPS NMEA Port (COM6) - Ready to use
LGE Android Platform USB Serial Port (COM7) - Ready to use
I wasn't planning to use the phone as a modem, so that driver does not worry me, but the USB storage problem is annoying.
In the phone, it does look as it connected. It offers the option to activate USB storage on screen, and if I click on the button, it says it enabled it, but nothing happens in the computer side.
I tested to uninstall everything LGE from the computer and restart from scratch, but same problem.
Ideas?
Update:
The LGMobile Support Tool in Windows says the phone IS connected, and that the software in the phone is up to date.
Do You see the phone into section computer like Removable Disc?

No. Nothing at all.
In "Devices and Printers" I have:
Under Devices:
LG Android Phone
LG Android (Modem)
LG Android (Serial)
LG Android (NMEA)
Under Unspecified:
LGE Bluetooth TransPort (COM4)
LGE Virtual Modem
In the "Device Manager" I have 1 "USB Mass Storage Device", with a yellow warning sign.
Under its Properties, in Device Status, it says: "This device cannot start. (Code 10)
If I try to "Update Driver" Windows says that the right driver is already installed.
FIXED !!
Updated LG driver to 3.5.
Still didn't work.
Then, I turned off the phone.
Removed the battery.
Put the battery back.
Turned on the phone.
Connected it to USB.
This time the USB driver started ok, and when I activated the USB storage I was able to see the drive under "Computer" in Windows Explorer.
I had turned the phone off and on before, so I think removing the battery did something that simply turning off and on wouldn't do.

USB 3.0 External Storage Device driver not getting Installed- [Solved]
Issue: USB storage device is not working on my computer, be it a USB 2.0 or USB 3.0 it just doesn't install the driver for storage device and my USB mouse and webcam does work.Everytime I plug in a USB flash drive of USB 3.0 External hard drive it beeps and gives error message that the device driver could not be installed.
Here is the steps I took to troubleshoot this issue and it got fixed.
1.Open registry by going to Run-> Type Regedit.
and Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
Highlight this key ({36FC9E60-C465-11CF-8056-444553540000} ), on the right pane, and then check if “Upperfilters” and “Lowerfilters” value are present. If so, please right click on the values and select "Delete" to remove them.
2. Now go to "C:\windows\inf" folder and check if these three files USBSTOR.SYS, usbstor.inf and usbstor.pnf are available.If it was renamed change the name as I wrote them or if they are not available copy them from "C:\windows\System32\DriverStore\FileRepository\usbstor.inf_x86_neutral_83027f5d5b2468d3"
And then go to "C:\WINDOWS\SYSTEM32\Drivers" and make sure you have USBSTOR.SYS and usbd.sys available if not copy them again from
"C:\windows\System32\DriverStore\FileRepository\usbstor.inf_x86_neutral_83027f5d5b2468d3"
and paste it to Drivers folder.
3. Open Registry editor by going to Run-> typing Regedit and Navigate to the following key:
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR" and ensure that the Start value is 3. and restart the system.
It will work..
thx

Turn off USB debugging.
Completely delete all drivers whilst not connected. In Windows click options show all devices, including hidden.
Install hisuite.
Next connect the phone then let it install.
Then disconnect and turn on USB debugging.
Let it install that too.
Can you see the device?
PS: there's only so many ways it can connect.
Nuking the driver then reconnecting afresh is the best way.
WORKED:
uninstall all of hisuite components with revo uninstaller
restart pc
connect phone via usb
turn on debugging
then open hisuite installer that shows as virtual CD in my computer
install it, and open
now, on phone ALLOW HDB
go to developer options, and as USB CONNECTION TYPE choose charging
and allow your PC to use phone
thats it

### The only way it worked for me was after being connected to the PC and have opened the HiSuite THEN GO to the last step and it looks is the only way it changes for charging only. If you don't have either the PC connected and on the HiSuite program, it doesn't change at all. Check bellow on the ###.:good:

It must of been a bug, once i updated to 9.0 it now connects fine and has done since updating.
If it still helps i think i got it.
Use the original huawei charging cable you got with the phone.
I tried it all.. tethering, debugging, hisuite etc.. but nothing worked
1. step Install HiSuite on computer,
2. step plug in your phone with original cable,
3. step HiSuite on computer will run by itself,
4. step select transfer files on your phone,
5. step computer will ask you if you all it to install HiSuite on your phone and click ok,
6. step on your phone pop up will show to install HiSuite on Huawei.
Maybe also go to settings - connections - usb thetering (if needed) and thick it.
Hope it helps, it did for me - but barley lost my mind...
Good luck,
Toni

Can't connect in fastboot, driver issue?

After doing lots of reading and trying many things I cannot connect in fastboot mode. I tried on two computers, holding volume down and plugging in usb cable. In CMD I run fastboot status and it just stays on <waiting for device>. I have connected other Android phones so maybe that is somehow messing up the device drivers, but I reinstalled them. Also when I run adb reboot fastboot from CMD, the phone restarts normally and not to fastboot but the volume down at least shows blank screen.
My goal is to get root, so whatever is easiest.

If you have used that computer for other phones previously, that might be the problem, Winodws is asigning the wrong driver. In your picture you have devices with warning triangles (no drivers). Try manually assigning the Sony driver. Depends on what you're doing, but you need a different driver for when you want to use ADB, so start the phone into recovery, connect it to your PC and look again in the device manager and manually add the Google USB driver.
If you are using windows10 and trying to install drivers, it doesn't tell you that the install failed. Restart the machine in safemode and look for 'driver signing disabled'

It's unclear to me which driver should be added to which device. For example should the Sony or Google driver be added to the section Android Devices, Portable Devices, or Sony?

I'm not sure what you're trying to do. If you want to flash a rom, you want flashmode, volume down (-) then plug in the USB. If you want fastboot it's volume up (+) then plug in the USB..
MTP driver is wrong, you need to uninstall it and re-install the sony driver. Windows chooses the wrong driver by default and you have to manually add it yourself to make it work.
Having said that you mentioned that you are getting ADB commands to work, so I'm confused, perhaps the google driver is in place, but the Sony one is not.
You need both, when the phone is in fastboot it's presented as a different device than when connected via ADB.
Hope that helps explain a bit.
But if you're having issues with the drivers, should you really be going down the unlocking road? It doesn't get you many advantages and breaks a whole heap of sh*t.

I had this problem before. My fault before was install drivers in usb-debugging mode, then a change to fastbook/flash, and then the phone is not recognized or connection properly - despite me thinking I had correctly installed the drivers.
Took me months to figure it out. Boot into windows, then connect your phone in all modes, flash mode, fastbook mode, standard, and usb debugging - and for each mode - install the Sony driver again.
The result will be, that for every mode - when you go to device manager - you won't see an exclamation mark. If you ever see an exclamation mark again - install the driver. You get the idea.
Regards,
I finally found the f**kin problem the invalid driver was hiding under "other devices" only when the phone was in fastboot mode. Basically I followed the instructions of user2021355 from here.
Start Windows in test mode (instructions)
download driver from https://developer.sony.com/develop/drivers/
in admin command prompt run adb reboot bootloader
if the above step failed, you have a problem with adb and the solution is something different
open device manager and carefully search for any errors. I found mine hidden under "other devices"
right click on the errored driver and choose update
choose browse my computer
select the driver you downloaded from step 2
verify if working by running fastboot devices and you should get a serial number

I thought the only thing it broke was the camera and there's a DMR fix for that. Does it mess up something else?

At least for me it wasn't enough to add the driver manually (I think because the invalid driver would still be there). So you need to right click on it, update, then browse to the downloaded driver.
OK I got it working with installing the driver, win10 bootet with disabled Driver Signature enforcement

I think we have different ideas of what adding the driver manually is

i have the problem as you and I'm also on win10. can you share how you installed the fastboot driver?
the adb and mtp drivers work fine for me, just fastboot is not working
unsigned driver under W10
try this one

I have the same problem with my Sony XZ1 Compact G8441.
'adb devices' shows my phone, after 'adb reboot bootloader' phone goes into fastboot mode (I think), the one with blue LED, but 'fastboot devices' does not show any connected devices. Same when pressing Volume Up or Volume Down while plugging the phone in.
After some reading I figured it was a driver issue, so I tried installing drivers from Sony XZ1 Compact driver and Sony Fastboot Driver.
Tried installing through device manager, right-click on faulty 'Android' under 'Other Devices', update driver, browse to download location.
With 'Sony XZ1 Compact driver' it found no installable drivers.
With 'Sony Fastboot Driver' it found an installable driver but had an error. Error said something like 'Did not find "Android ADB Interface", installation failed'.
I tried figuring out what you guys meant by 'installing driver manually' but I don't understand. Is it what I tried above, or something else?
My goal is to be able to install TWRP, which needs an unlocked Bootloader first. I followed the instructions on the official Sony Website for that.
Sorry. Delete this.

If you're using Windows 10 you'll have thought that you'd have installed the drivers, but W10 fails on driver install and doesn't tell you.
Start the pc in 'safe mode' (hold shift while restarting), then choose 'driver signing disabled', install the drivers agiain. This time it should work.

No, that did not help. The same problem remains. Phone is recognized when powered on by 'adb devices' but not recognized after typing 'adb reboot bootloader' and 'fastboot devices'.
Thanks for your suggestion though.
I got the problem that no matter what i do i can't install the driver.
Booting windows 10 with driver check disabled does not solve my problem.
Once i selected the driver to install i end up with a questionmark in the device manager above the android device. Taking a closer look reveals that there seems to be no driver installed.....
Any advice?
I tried:
1. Booting with driver signature check disabled
2. Switching windows 10 into test Mode
I booted ubuntu from a live usb stick and went from there. That works like a charm without the need of installing any drivers
Both solutions do not work....
