So my phone has unlocked bootloader, I haven't unlocked it myself, it was when I bought it. How do I know?-when I go to bootloader it says "PhoneUNLOCKED" and "connect your device via usb" or similar.
I have enabled USB debugging, connected the phone to my computer, installed drivers and everything. I open adb, check if my phone is connected, it says yes, and then reboot my phone in bootloader it still says both "phoneUNLOCKED" and "connect your device via usb". So then I typed devices in adb and it says there are none connected. Wth? I was actually trying to flash twrp img but since there's something wrong with bootloader or connection, I can't. So can anybody help? Is this a connection problem?

Hello; I am a newbie, ex IPhone Fanboy Junkie jailbreak/unlocker and I decided to switch to Android so I am starting all over again. I am trying to root the phone. I downloaded fastboot, superboot, the Andriod SDK and installed, or at least i believe I installed the usb drivers. It mounts fine on both windows and mac and on windows it makes that sound and says its attached when connected. But when I reboot into bootloader mode to unlock it, windiows makes those 3 quick beeps because its not recognizing the device in bootloader mode. I have "usb debugging" checked on the device. Can anyone tell me what I am missing?
Try "adb devices" in normal mode or "fastboot devices" in bootloader to confirm you have the drivers installed correctly and your computer recognizes the phone.
If it is recognized correctly in normal but not bootloader, confirm that your phone is in bootloader mode (not fastboot). If it is not recognized in either, work on installing the usb drivers correctly.

You cannot do fastboot devices in recovery mode.
in recovery mode you can do adb devices to check if your phone is recognized by your laptop
in fastboot usb mode, you can do fastboot devices to check if your phone is recognized by your laptop
I have the same. Was working fine beforehand now nothing. When I connect to the PC with the phone booted it connects then a second or two later disconnects, like it "doesn't like" the connection. It tried to install HTC MTP driver but fails as it says the "device is disconnected." Fastboot USB works fine though and I can carry out fastboot commands from bootloader, but no ADB

I tried fast boot devices in fast boot USB by going into minisdk. Didn't try in recovery would have been good to try adb devices in recovery because I was stuck in that when first tried the custom recovery but a hard reset kicked it back out. Got recovery sorted just wanted to take nandroid backup off phone to PC and put root files which I'm still trying to get best 1's any idea where to get them where URL link is working? I've tried fastboot so doesn't work and basic trying to connect phone to PC for file transfer doesn't work either

Ok so not only person. When I try connect mine doesn't even flag up I've connected a device USB debugging starts up on phone but have just noticed USB connection doesn't show. Plus I connect to PC and doesn't make the sound as I've it recognized my connecting anything. Fastboot USB comes up empty. I've been spending a couple hours here and there for past 2 nights trying to set phone up ready for rum runner. But my other question is if I'm already on htc_001 there's no need for me to change CID num anyways? Thanks
Try going to command prompt and typing in set devmgr_show_nonpresent_devices=1 followed by start devmgmt.msc
Click on view and show hidden devices. This will show devices which are not connected but have been installed. Look for something like android phone or android device and update the drivers by selecting update driver > let me select > have disk and then select the driver from here:

Try that and see if it works
I'm all sorted now thanks just kept at it.

Hello!
I am trying to root my phone, which requires and unlocked bootloader.
Here are the steps i have completed:
1. Got the unlock code.
2. Installed adb and fastboot drivers.
3. Installed HiSuite
4. Connected the phone to my desktop (windows 10).
Here i have to mention that the pc recognises my phone, and it is listed under devices. USB debugging and OEM unlock are enabled.
5. I opened cmd in the folder where abd is installed. Checked that abd devices finds my phone (which it does).
Here is where the problem comes in. After booting phone into fastboot (using adb reboot bootloader), i tried to find my phone using the command fastboot devices.
This doesn't find the phone. If i try to unlock anyways, it gets stuck on waiting for devices. I tried the same steps on a laptop (also running windows 10) and the problem stays the same.
Help is appreciated.
EDIT: solved the problem by using a windows 8 installed laptop.
Uninstall HiSuite, it may interfere with the phone's connection. It is not used when unlocking/root.

Thank you for your reply, but this didn't work.
To add a detail, the reason i installed HiSuite was, because in fastboot mode it says:
"Please install HiSuite and connect your phone to your computer with an USB cable.

You can try using this tool to unlock bootloader:
http://forum.xda-developers.com/p9/development/tool-srk-tool-huawei-bootloader-root-t3374068
I personally used this and worked flawlessly, make sure to get the latest version of it if you do.
If you are in fastboot&rescure mode, try the command "fastboot devices" and see if the device is detected, if not try unplugging and replugging phone

Will try the tool when i get home from school, but fastboot devices doesn't detect my device.
EDIT: The tool didn't work. It is stuck on waiting for device.
Fixed the problem by unlocking on another laptop (has windows 8).

formerly rooted H811. I unrooted with supersu and attempted to relock the bootloader. But It didn't take. It appears to be in some in between galaxy.
I get into fastboot, but "fastboot devices" comes up empty.
Would like to lock to update to 20X. No PC, only Mac.
LG Bridge sees USB, but not phone.
Help appreciated.
You do realize locking the bootloader will perform factory reset and wipe your data. Are you trying fastboot through MAC, not sure how it is different from PC so if that is causing the issue can't help much.
Is usb debugging enabled, and you have given permission in the pop-up that pops up on phone screen when you connect it to MAC/Computer the very first time? It is possible you missed that permission pop-up the first time and now permission is denied permanently. You may wanna uninstall and reinstall LG driver/device, connect phone again, and look for that permission pop-up on phone screen and allow it. Try connecting usb cable in different usb port too, that might make the pop-up appear again. Also, remember if bootloader is altered or you got custom recovery, phone will possibly soft brick and you will need to use LG Bridge or LG UP with phone in download mode to reflash kdz. Hope this helps.
Edit: For the permission pop-up to show, the phone needs to be turned on, be in mtp mode, and usb debugging to be enabled. Then once you have given permission, you use adb command to reboot into bootloader or i think with phone off, hold the volume down button while you connect to usb cable and not let go of the volume down button till phone is in fastboot menu.
Hello all, I have a strange problem on my xiaomi 8 phone.
Every thing works fine, the phone is BL unlocked, with global rom installed and can be OTA-updated.
Now I want to re-lock the Bl (because of google pay), so I booted to fastboot and the strange thing happens. When I connect to the usb port of my win10 pc, nothing happens, the device manager also show no new device or unknown device. And I als connected to my ubuntu server, dmesg show nothing, and lsusb also show nothing new.
So the issue is, in fastboot mode, my phone seems not be responsed the usb connection. This is boring, because I also accidently replaced the twrp with stock recovery, now I can do nothing on my phone without the fastboot connection.
Any one has an idea or simillar issue and have a solution for it? Thanks in advance.

It sounds like you accidentally relocked the bootloader.
If so you will need to repair the phone in EDL mode by using QPST. There are plenty of how to guides available. You can buy a EDL cable from Amazon
