I recently got a BLU VIVO 6 and i just want to unlock the bootloader(and then install TWRP and root it etc).
the phone is recognised with ADB Devices, but once i put my phone into fastboot mode ( and type into prompt fastboot devices ) nothing comes up.
OEM unlocking is on
I've swapped out USB ports
I bought a new USB cable for the phone
Reinstalled drivers, manually.
halp, what do
:crying: :crying::crying:
Try a diffferent computer or uninstall all the drivers and reinstall only the ones that are needed. Most probably its a problem with Drivers.
It was, thank you. I was able to unlock the bootloader, now my issue is with TWRP. the phone is softbricked at the moment, and has been for a few day. I going to keep trying to find out how to get it working again.
Do you have the recovery file you want to install? If so just flash it from fastboot. Otherwise find the recovery in the forum of your device.
Hit thanks if it helped!

OEM unlocking and USB Debugging enabled.
ADB never finds the phone in my windows 10 install no matter what drivers I force it to use. - Tried USB 2 and 3.
Fastboot does find it if I manually start it in fastboot mode, but it can't do anything to it
Fails to write when doing oem unlock
Just sits there if I tell it to write the recovery image.
Phone functions fine, I just want root and a 3rd party rom to be rid of any built in spyware.
Any ideas? any way to root it without flashing then I can just have the twrp app flash it?
Nevermind, found a way around it. This dialpad command made it work

Hope this will help someone with trouble getting ADB/Fastboot to work. I assume you have a similar environment to me: Windows 10, with working ADB drivers on another device (LG G4 in my case)
Set up LeMax2 in developer mode and enable USB debugging as usual.
Plug in usb and dial *#*#76937#*#* check the box that says "Enable AT Port"
The device should immediately give you the approval message for USB debugging.
Note: This will not stick after a reboot.
Once I had this working, I did an adb reboot recovery, but fastboot still did not work. With the device connected and at the stock recovery screen, I had to open device manager, delete the LeMax device, and allow it to detect again. Finally it appeared in fastboot devices and I was able to flash recovery.

My K7 is T-Mobile LG-K330, Android 5.1.1, kernel 3.10.49, Build LMY47V, vers K33010j
I have searched and tried many root guides. All end the same way. This isn't new for me as I have rooted and installed mod roms on several phones and a tablet.
The main problem seems to the phone will not show as connected to the root tools. I have triple checked the developer mode ena and usb debugging ena and tried OEM unlock both ways.
I have the latest (as of today from XDA, minadb and kingroot (PC)). Both are installed on my Win10Pro comp.
The phone USB drivers must be in place as I can plug in the usb and the K7 comes up in the This PC list and I have access to the folders. I must be missing something.
adb devices -l
daemon starts but no devices are listed
fastboot devices
none listed
kingroot
all is well up to the point where it tries to "connect" it just fiddles in circles
I waited 15 min and Xed out.
This may be related: I cannot boot to the recovery screen. No matter how I hold the power and up volume I always get the T-Mobile screen and android.
Has anyone seen this or have any suggestions?
Happy Trails
I had similar problems with my K7.
I had to download a different minimal ADB / Fastboot tool from http://forum.frandroid.com/topic/246460-root-and-recovery/ .
Once the bootloader was rebooted the phone had on-screen instructions.
Use this https://forum.xda-developers.com/lg-k7/how-to/t-mobile-lg-k7-thread-t3481844 and the site above for instruction.
Put your recovery twrp-image-3.img and the SuperSU.zip on a micro sd and insert it in your phone before you start.
Also put the twrp-image-3.img in the ADB program folder on your computer.
Once the bootloader is unlocked, instead of typing: fastboot flash recovery twrp-image-3.img .
Type: fastboot boot recovery twrp-image-3.img or fastboot boot twrp-image-3.img (I don't remember) (only one will work).
Then once in twrp install the recovery ( twrp-image-3.img ) and then the SuperSU.zip from the SD card.
Also make sure you check the box and allow your computer permission to connect to your phone when you first connect them, after you enable usb debugging on you phone.
Good Luck.
I tried using the Tool All In One to unlock the bootloader and manually through the adb and fastboot terminal. ADB recognizes the device even though every time i reboot to bootloader through adb or manually through the phone recovery and manual buttons it never sends me to the bootloader. i was able to flash the stock firmware with SP flash tool. I really just want to install TWRP. i have been able to root this device with Wondershare dr.fone root program. I wanted to get it to work with the All in One tool so i can install TWRP to install custom firmware. If anybody can point me in the right direction on why the bootloader never works and fastboot? Maybe this model the bootloader is unaccessible? And if i cannot get to fastboot to unlock the bootloader can i still install twrp somehow. Also when using fastboot command it shows the device id it just says waiting for device everytime and cannot get it to recognize past that point. Not being able to get past this phone problem has been really bothering me and irritating me lately so hopefully i can get it resolved. I will be back later to see if anybody knows a solution to this. it seems like i have been trying to do the same thing and maybe im right and fastboot mode and the bootloader is locked and currently not possible.
Hi all,
Just bought yesterday this phone and after doing typical actions like android config (oem, debugging, etc.), installed adb and fastboot. PC recognized command adb devices and shows the phone but when I reboot to fastboot mode, it stucks and the device manager shows unknown android.
Have read all the tips here, forums, youtube, etc. but no way. Tried in 2 different computer with same results. Installed last android studio with sdk manager, same error. Installed oneplus drivers and also the same.
Even I have tried a different cable but no success at all.
This is so frustrating situation, ever more considering that I'm not newbie at this (years ago always changed rom every month and smartphone every 2 months).
Any advice? Format pc? Install other windows in other partition?
Or selling the phone and buying another brand

Did you select always allow from this computer after enabling debugging and plugging your phone into computer when phone was booted and running(not in recovery or fastboot. Also adb does not work in the bootloader only fastboot commands. Secondly search for the insecure modded stock recovery if you want to do adb access commands in recovery. There is also a fastboot d mode on our phones which look like recovery but you can flash all partions via full fastboot to get to fastboot d your phone has to be on then you type adb reboot fastboot

No prob
Good day.
I've working on rooting my Lenovo legion 2 pro CN ROM, and currently stuck in the process of fastboot flash image.
It seems like the phone won't be able to detect by my laptop, after I ran the cmd #adb reboot bootloader. There is nothing showing up on the #fastboot devices.
I've checked on some others thread, by understand the fastboot are communicating through the side port instead of the below port, been reseating cable on that ports, but still no luck.
If Anyone who can guide me through this would be very much appreciated.
install device driver in device manager
