ADB device not found - LeEco Le Max 2 Questions & Answers

Hi. First of all I want to excuse me that I' m asking a common thing several times threated in other posts.
I'm working now 2 days on getting another rom on my lemax 2.
I have installed the driver for the phone on my windows 7. system manager shows a propper installation. ADB driver's have been installed. The phone is in developper mode and oem and usb debugging is turned on. I switched to MTP and to PTP to make my device visible for ADB. But when I'm trying to see if my computer shows the mobile phone in CMD with the following command "adb devices" there will never be something listed! I tried already a lot... Uninstalling drvers for ADB, tried different drivers... And so on... Does anybody have an idea to help me??

Same problem here. Phone doesn't show, ADB can't connect. I am starting to get frustrated.

Most likely a problem with the usb driver, did you try another phone? I had the same problems and ended up doining it under linux afther a couple of hours messing in win10.

Linux definitely is the better choice.
The fastboot drivers are different from the ADB drivers, and in Windows 10 you might have to switch the driver after fastbooting the phone.
It's really really silly and took me hours to find out.
You can change them in device manager, find the USB device there and update its driver. You don't need one from the web, just take the fastboot one from the list that Windows offers.

I have no second android phone to test. But I tried already on OS Win 7 & 10 with different drivers on Win 7 as well. On win 10 the driver was already given by Windows, no need to install. I think that the problem has something to do with the phone, but I can't find the problem. It must be something with authorisation, that Win Os will recognize the Leeco correctly to have access.

I finally found a good working driver for WIN 10. I found it from a Chinese chatting group, so use it at your own risk.
Below is the share link.

You will need to boot your phone into bootloader, connect to computer, manually switch the diver via 'Browse my computer for driver software" -> 'Let me pick fromm a list of device drivers on my computer"-> "Have Disk".

Hi all,
After reinstalling Windows7 32-bit on my laptop, I ran into the same issue as you guys here. What I did was to install pdanet and the adb interface worked. However, I could not get into the QDLoader 9008 and also Diagnostic Driver was not working, simply the drivers could not get installed no matter what I tried. I searched quite a lot of time how to get make it work and looks like there was a zip "QDLoader HS-USB Driver". You can google it and it has 32-bit and 64-bit installations. I am not very sure if I had to install pdanet but that was the first step to make it work, at least to have adb.
I'm sure that you guys found the answer already, but I wanted to help others as well if they run into the same issue.

if you're sure it's not a driver issue you can try the following (solved the problem for me):
on your windows machine navigate to "c:\users\<insert your user name here>\.android" and delete the file "adbkey".
either jump directly to the folder or turn on hidden/os files in explorer and navigate there.
now plug in your phone, the rsa-key dialog should pop up.
if not, that wasn't your problem.
btw. i'm using "universal adb installer".

This Method Works Perfectly.... After Enabling the AT port.. the drivers begin installing immediately. Have Patience. They will all install.
