Lenovo Zuk Z2 not detected by PC - Lenovo ZUK Z2 (Plus) Questions & Answers

Hello, (I'm new here so forgive me if I am not very clear) I have a Lenovo Zuk Z2 also known as Lenovo Z2 Plus (Indian ROM) I'm trying to flash TWRP on it, but the problem is that my PC isn't detecting my mobile in ADB the list comes up empty, I have installed ADB and Fasboot driver's latest version and also turned USB Debugging on placed the bootloader unlocker in the directory too, if I give command to reboot the bootloader the PC tells me that "null" device is detected, also when I connect it in PC my phone doesn't even ask for USB Debugging permission. I checked it in devices and it shows that adb interface driver not installed, if I manually search for adb driver I niether find ADB devices nor Android Device. Can anybody please help me?

Install zuk cdrom file and restart pc

Many thanks.. Its November 2017 and here I was stuck with fastboot not working to unlock the phone. Your post helped me :good:

Help!
My z2 is getting connected to the PC but it's not showing in my computer
I have Windows 8.1

Windows 8/8.1/10 connection
I had the same problem with detecting HTC one M7 and Zuk Z2 on adboot. Problem persisted for much time on M7 until I finally found a solution. There was a patch online which made changes to registry. Only then adbdevices command was successful for the first time. Try coming the net for windows 8/10 patch file for it. Dont have that file now. Maybe try this xda thread file https://forum.xda-developers.com/htc-one-s/general/guide-fix-fastboot-windows-8-1-t2858337

Computer finding G4 through ADB

Has anyone gotten their computer find their G4 through cmd (adb devices). I cant get the adb message on my phone to allow access to my computer. I turned on and off usb debugging several times but i still don't see the message on my phone to allow access. I let me computer download the drivers when plugging up my G4 as well as allowing the install of PC drivers.
yes, working great for me. Do u have updated and right drivers? u find tread here with right drivers..
Sent from my unlocked and rooted LG-H815
I was having the same problem..
You need to install the LG Drivers and then your phone will connect via adb..you will be asked on your phone to allow the port connection after installing the proper LG drivers. Verify and you will be good to go..
I used these ones below in the attatchment or you can grab them from.....
http://www.theandroidsoul.com/download-lg-g4-driver-for-windows-and-mac-mtp-adb-download-mode-77723/
I think I found the issue. I had Note 3, 4, Nexus 6, S6 edge, and G4 all still on my computer in the device manager. I uninstalled all of them plus I uninstalled the adb driver in device manager. Plugged my G4 back in and ran the PC driver update via G4 and it worked. I can now see my G4. Don't know if I had to do all that to get it working but hey it worked for me.
I was having issues with this myself and didn't find a solution. I found out that I was having better luck switching it to Camera PTP from the notification dropdown. Sometimes I have to toggle to MTP back to PTP, The dev notifcation should appear when it is actually connected.
1. PTP
(1a. switch to MTP back to PTP if it doesn't work)
2. 'adb kill-server'
3. 'adb devices'
-If you see your device, you can try to 'adb connect **IP**' but it will most likely say it was unable to connect
4. give it your adb commands you want
It's the only way I've been able to get adb, hope this helps!
I was having this issue also. After install win10 then adb connection to my LG G4 (h818) was not detected. Back to android.com, it said that if general USB driver doesn't work then we must find OEM driver to the producer web. LG ADB Driver was about 17MB. After installed the driver then it was immediately detected. Thank God, finally.
I have silly problem. I bought used G4 LG from someone found in online forum. Checked all series on phone (sticker), on software "about phone" all showing LG H815 software version H81510H, but by adb ( linux machine ) showed H812xxxxxx .... set on developer option debugging the command "adb reboot bootloader" just send device into android boot ( device boot ). I wish to unlock the bootloader and put CM. Hard button option > pushing vol up + power button simultaneously did nothing, vol up + power button then > connect to PC via usb, did nothing ( just send phone to device boot ) ..... I have no windows machine

adb devices: no device found, why ?

Just a quick question.
Im unable to access fastboot or bootloader mode through adb command line.
I turned on usb debugging, connected phone to usb cable with my pc, run command line in platform-tools - adb devices and nothing happens.
I think i know the answer, but i want to be sure. Is it because i dont have unlocked bootloaded (OEM Unlock, still 6 days to wait)
Do you have the proper drivers? Try downloading the universal ADB drivers.

Switch USB mode to PTP instead of MTP. I don't know why, but it works like that after Android KitKat/Lollipop release. Used this trick on LG G2 mini and now on my P2
I dont know if i have correct drivers, but i think so

My Xiaomi Redmi phopne is detected correctly, but its rooted and OEM unlocked
edit:
It's fine now. Its unbelivable what a mess is with adb files/usb drivers and similar. There is so much that can go wrong.
I wiped everything and installed minimal adb and fastboot + lenovo usb/mtp drivers
Now pc detects my phone.

unable to unlock bootloader

Yesterday i got my zuk z2 plus 64gb. I installed adb driver on pc & enable usb debugging from zuk z2 plus. I connect my phone to pc, Grant the usb debugging permission, extract the adb setup, shift button & write click. Now the cmd is open. When i enter "adb devices", my device is not showing.
I always use something called 15 Second ADB Installer when setting up ADB and Fastboot on a new computer. It installs all the correct drivers as well, so maybe that would solve your issue. Also, be sure to check Device Manager in Windows and see whether there are any devices showing with yellow caution symbols besides them.
If you find your phone displaying like this; right-click and choose 'Update driver', then 'Browse my computer for driver software' and 'Let me pick from a list of available devices on my computer'. Find Google Inc. and choose the one which says 'Android ADB Interface'. You have to do this AFTER running the 15 Second ADB Installer otherwise it won't work.
Definitely driver related, remove and reinstall etc but don't give up haha sometimes its a PITA to install the correct drivers...

Fastboot not possible

hey guys,
I m trying to unlock the bootloader on my Z1C but there is something wrong with the fastboot.
If I follow the instructions from sonymobile.com in order to unlock the bootloader, I stuck in the fastboot section
My command fastboot devices returns with no result. The command line just reappears.
If i continue with fastboot -i 0x0fce oem unlock 0x..... then the system says: waiting for any devices and nothing happens.
I tried the Flashtool to establish connection and if the device is turned on then it gets all conections properly
but if I want to use the flashtool bootloaderunlock it works in flashmode but then i have to switch to fastboot and it doesnt recognize the device. it says i need drivers.
if i want to install the driver package then i get an error while installing the google usb drivers.
i tried to uninstall and install the google usb drivers wirh sdk manager but it doenst help
does anyone have an idea what to do?
