Hello everyone..
I got an LG device that is stuck in CWM recovery, and I want to upload a file to the device using ADB. and I have two questions.
1. I'm running Windows 8.1 64bit, and tried several ADB drivers but the one that's detected was a Samsung driver, now the phone reads "Samsung android ADB interface" in the device manager. Should the device work properly?
2. When I typed the command "adb devices" the replay is normal but it says "unauthorized" instead of "device" or "recovery". Any idea what causes this or how to fix it?
Thanks in advance.
No bootloader interface is found !
Hi experts.
ADB interface driver can be easily installed when "USB debugging" is enabled in phone because this way it allows Windows to detect a device with name string "ADB interface driver" and its specific vendor id along with product id. In my case, VID is VID_0bb4 and PID is PID_0004&MI_02 ( this PID is for ADB interface only). There is no problem in installation and detection of "ADB interface". adb reboot-bootloader is working from both Windows 7 64 bit command prompt and Ubuntu 15.04 terminal. Till now it is okay.
Now, this is what I am stuck at.
if anyone understood me with previous part please help me unlocking bootloader because unlocking bootloader requires switching into "fastboot" mode. With ADB command I am able to switch my phone into "fastboot" mode successfully. Now I disconnect USB cable from phone. Phone is still in "fastboot" mode ("=>> fastboot ..." written in lowest left corner on the screen). I connect USB cable again. No other new device is found this time. Fastboot commands that is detecting my phone successfully is with that adb interface port. Why is that ? At least I have learned from Internet that "bootloader interface" is required for Windows to unlock bootloader. Now after searching through many android_winusb.inf file from USB driver folder, I found out that the device id (VID) is same for both "adb interface" and "bootloader interface" BUT product id (PID) is different for both interfaces. Now it is VID_0bb4&PID_0FFF.
According to inf, Windows/Linux will only detect "bootloader interface" when the device which here in this case is a phone provides the VID_0bb4&PID_0FFF through the USB cable. The real problem here is my phone which is Micromax Bolt A065 (Kitkat 4.4.2, Kernal 3.4.67) is providing only one VID/PID in both ADB and fastboot mode and that is of "ADB Interface" only.
How can I get my phone to send that "bootloader interface" vid/pid to Windows/Linux in fastboot mode ?
Latest Android SDK is installed.
Tested with many adb/fastboot USB Drivers from Internet.
Hello Guys,
i have a problem and hope you can help. i wanted to open my bootloader.
If i connect my G5 international with PC in fastboot the PC doesn't recognized the device.
In the device manager i can see "Android" as unrecogniced "device".
i tried several ways to update this driver but nothing helped.
So i can boot the fastboot from pc with "adb reboot fastboot".
The command "adb show devices" no problem too
But if i write "fastboot show oem-devices" i'll get the message
<waiting for device> and nothing happens.
have you enabled "usb debugging" in developer options?
Yes i enabled udb debugging and unlock via oem also.
Windows 7 will recognize an fastboot device but doesn't update/configure/install fastboot driver
fixed:
update driver -> search on computer -> Take from List -> CWM driver -> LGE ADB
pc got it
Hi everyone.
I apologize if this was already asked.
I own a Symphony H50. I am trying to install windows via change my software but it shows device too slow or protected by manufacturer.
So googled it and found that i need to unlock my boot loader.
So I installed adb,fastboot,drivers including bootloader interface driver. And booted into fastboot mode. And typed "fastboot oem get_unlock_data" and the command prompt shows 3 dots (...) And the cursor keeps flashing. And no confirmation message shows up on my phone.
It only shows "FASTBOOT mode".
Another thing i found out while installing adb drivers that it listed my phone manufacturer as HTC.
So is the problem with my phone?
And how do i fix it?
It may be a problem with driver, uninstall the previous one and install Koush universal adb driver from kaushikdatta.com
Use the link given below for a thorough tutorial to replace drivers.

Thanks for reply,
I'll try the drivers.
Though my adb drivers are working fine. My issue is with fastboot.
When i boot into fastboot mode it shows "FASTBOOT mode" on a black screen.
But i would try with the
That black screen with fastboot mode written at the bottom comes up on every phone when you boot into bootloader.
Please read the whole guide before proceeding.
You may skip the driver and adb installation part if u have already taken the measures I stated before.
Try this,
Download adb and Koush Universal adb driver and install them on ur pc, always install the driver first and don't install the drivers adb setup asks u to install.
Run command prompt as administrator.
Open the folder in c drive where adb is installed, u can use file explorer for this.
Press Shift+right click and select open command window here.
Enable USB debugging on your phone and connect it to the pc by a USB cord.
Enter command "adb devices" without quotation marks.
If it shows some device connected, only then proceed further.
Enter command " adb reboot bootloader"
Enter command " fastboot devices", if it shows some device to be connected, only then proceed further.
Enter command " fastboot oem unlock".
Ur phone may then ask for final confirmation on the phone screen, select yes.
When procedure completes, type "fastboot reboot" and ur phone will reboot.
U can now use Kingoroot or any other tool for rooting.

The bootloader is blocked by code combination. If you try to see more attentive you'll notice the tiny message on the black screen while rebooting.
