Hello kind folk,
I've been experciening some trouble unlocking the bootloader of my LG G4 standard EU version.
I was using LG's way so i needed the Device ID. I enabled OEM unlock and usb debugging.
Downloaded adb and the drivers and everything worked fine the devices was found and i confirmed usb debugging.
When i issue 'adb reboot bootloader' the device goes into fastboot mode and doenst responds to commands from there,
it just keeps waiting for device. Also it doenst find it with 'adb devices' once in fastboot mode.
I tried finding differend methods but they all come down to this one, i have no idea what to do at this point.
Really could use some help here

HI I am trying to root my 1+ and the drivers while it is in android debugging mode arent installing correcty. So it is being recognized while in regular mode, but when I check usb debugging it says my drivers arent istalled correctly. I have tried both the universal and the samsung drivers from the unlock bootloader and rooting thread at the oneplus one forum thread. Any help much appreciated.
Hello,
First of all I'm French so sorry for my bad English.
I just purchased a Zenfone 2 Unlocked (Model ZE551ML), and for some reason i thought it was a good idea to root my system.After rooting I disabled USB debugging and yesterday I decided to update my system software to a newer version without knowing at the time that it wasn't a good idea with a rooted cellphone. Now the android phone is stuck in boot-loop and after factory reset/wipe cache it is still doing the same-thing. After searching the web, I concluded that flashing the software using adb software was the best solution but I soon after realized USB Debugging was disabled and after checking with adb I get this message when I try to use command ''adb sideload file.zip (where file.zip is the file name of the Asus firmware)''
Message :
C:/adb> adb sideload system.zip
loading: 'system.zip* deamon not running. starting it now on port 5037*
* deamon started successfully*
error: device not found
Just to make sure everyone knows, the zenfone was plugged via USB and I was in ''apply update from ADB'' in the recovery mode.
How do I proceed ? Is Flashing my zenfone 2 the best option for my situation? Is it possible without USB Debugging Enabled?

No bootloader interface is found !
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.

Can anyone help me on Getting My LG G PRO F240L back, it stucks and always restarting on CWM RECOVERY saying "Device Unlock! So Boot Success!"
I've tried to Flash KDZ LOLLIPOP using LG FLASHTOOL 2014 but stucks on processing . I Bet the problem is the "UNIDENTIFIED DEVICE -> NO DRIVER FOUND" When connecting it to Windows 7 Ultimate, I went to Device Manager and sees "UNKNOWN DEVICE" I Uninstalled it and Tries to Connect again to DOWNLOAD MODE but Unfortunately " NOT RECOGNIZED " the device I have changed different USB CABLES and restart the Laptop Several Times . I manage to UPDATE the DRIVERS but the Problem was I can't connect the Pocketwifi via Wireless Connectivity, I can Connect it with The Cable Inserted on the Laptop but Where the Phone should Get into Download Mode by the Laptop IF there's an inserted pocketwifi on it. Please Help who knows what to do with it... Or is there something that should Fix my LG G PRO that Stucks on CWM .

Hello is there any troubleshooting guide I can follow to find out why my redmi note 6 pro is not being found when I run the ADB devices command when i'm in fastboot?
It shows up fine when it's booted into the android OS.
I've enable USB debugging and authorized my PC. The device is unlocked as well.
Any help would be greatly appreciated.

You installed the Xiaomi drivers?
Connected the phone to a USB 2.0 port on you pc? (if you don't have one, use a USB hub)
Aren't ADB and fastboot 2 different things? I only used fastboot in fastboot mode and ADB in recovery... I think your behavior is normal.
