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.

Hello everyone,
I opened this thread becasue of forum rules.
So I have got a Chinese tablet that internal name is C-712 and Usb Vendor is 1F3A:1010.
I tried to install a custom rom and my device isn't open now I have got only a white screen.
At first I can see with adb devices as
adb devices
xxxxx recovery
and I tried the
adb reboot-bootloader command
and rebooted...
After reboot my device don't seem in the device manager as "Android composite ADB Interface" but showing as "USB Developer"
So I tried to search alternative driver of this device in my computer and I found another one now I can see as "Android Bootloader Interface" in Windows 7's device manager.
But this device don't recogize by adb devices nor fastboot devices.
Is there any tool or way to reinstall my original img file into this device.
Best regards

Ok. I solved my self...
So you need PHOENIXCARD V3.09 software and a sdcard.
And follow the instructions for formating of sdcard as production.
You may find that software in google.
Thanks for reading.

Hello,
I want to flash TWRP 3.0 to my Galaxy s2 so i can maybe install Lineage rom. I have ADB command enabled and using "adb devices" it does recognize my phone and under device manager you can see it recognize the phone as android phone. But when entering into fastboot mode and entering "fastboot devices" it returns nothing. for some reason it doesn't recognize the phone as it should be. In device manager it does recognize it as "samsung mobile usb cdc composite device".
I have windows 10 and i tried even on mac os but no success.

Why don't you use Odin instead.
And also be aware that twrp won't work unless you have an isorec kernel, there are many guides you can use, for example the one in my description.
Thank you for your quick reply. I have found this guide which i did almost all the steps and just waiting to see that the rom is loaded.

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.
Hello Friends,

while I am running the command "adb devices" it returning with the device name I have connected i.e. Oppo F15 but when I am running the command "adb reboot fastboot", "adb reboot-bootloader", "adb reboot bootloader" the device reboots but not going to fastboot, it just reboots in normal mode.
Please help me if I am missing something in this. My device is running with Android version 9.

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.
