I've checked other threads but other similar threads were able to get the phone detected in Device Manager so...
I went to factory reset my old Nexus 4 after using it whilst my LG G4 was being repaired. Instead of wiping the data, I accidentally wiped the entire phone, OS included. I wasn't paying attention to what i was doing due to working at the same time and as a result the phone now only boots into TWRP and fastboot mode, but nothing else.
I tried to connect it to my windows 10 laptop so I could flash a new ROM but my laptop can't find the nexus 4 at all. Not when in recovery or when in fastboot.
Opening device manager shows that it is not there at all. There is no ACER usb device driver, nothing that resembles the nexus 4 at all. I've attached an image showing what device manager shows when the nexus 4 is connected and in recovery mode.
As you can see, there are no drivers I can uninstall. I have installed the google USB drivers from Android SDK manager. Still doesn't show. ADB doesn't work either.
I have tried multiple USB cables and every USB port. The phone charges when using an AC adaptor and charges when connected to the laptop. I can't try a different computer because I do not have access to one. Frankly I'm at a loss as to what to do.
When my nexus 4 was previously unable to connect I was able to see the device and just had to uninstall/reinstall/update drivers to get it working. This time, I can't seem to do anything. My LG G4 connects fine and without issue.
Anyone able to help?
The only way to really tell if it is a software or hardware issue would be to try another computer with Win7.
You may be able to flash a custom ROM with a OTG drive as well.
I had the same problem. When using adb and fastboot I get errors about like "error: device '(null)' not found".
Youtube video with id t0pV2pSw2N0 (sorry I am not yet allowed to post external urls) was helpfull and now I can see Android Composite ADB Interface again in the device manager. I still can not use commands adb and fastboot with exception of adb sideload. Unfortunately I have not yet succeeded to flash an image succesfully with sideload.
first try 2 remove any current drivers that are installed.
then u should experiment with different drivers.
the SkipSoft ToolKit have a huge selection, try each one of them (one of them should work).
begin with the ULTIMATE drivers and Adb/Fastboot Installer and if it don't work use the toolkit drivers.

For me it turned out that MTP was enabled by default. After each restart MTP was enabled again. Now I have disabled MTP and my device is found by normal adb command.
Steps:
1) Start your device in twrp recovery mode
2) In main menu go to mount and tap "Disable MTP"
3) In main menu go to advanced -> adb sideload. Wipe caches and slide to start sideload
4) On your pc go to the command shell
5) Start "adb sideload <image_name.zip>" (replace image_name.zip with a valid image). It does not matter whether this fails or succeeds. Only thing important is that adb connects to your device.
6) Start "adb shell getprop persist.sys.usb.config". As result you will see the actual setting of the USB configuration your device when starting up. In my case it responded with "mtp,adb".
7) Start "adb shell setprop persist.sys.usb.config adb" to enable only "adb" configuration
8) Repeat step 6 to check result
9) Restart your device in recovery mode
10) Start "adb devices" to check if your device is now listed.

I tried removing all USB drivers and then using the toolkit and tried installing each driver. None of them allowed my PC to detect the nexus 4. As you can see in the attachment, nothing in device manager remotely resembling my nexus 4. This is after uninstalling and reinstalling and also updateing the LG G4 drivers (it makes no difference).

Unfortunately I don't have access to any other PC for this purpose. I can't connect download software or connect USB devices to the PCs at work due to security. I tried an OTG drive but TWRP wouldn't let me mount it, apparently OTG is not enabled by default for the nexus 4.
I've tried all 3 USB ports, several different cables but no luck. I guess that's it for this nexus 4 then?
If the phone is not booted into its ROM, ADB commands won't work. You need to use "fastboot devices" with the phone in bootloader mode.
You android device will reboot in several different boot modes (fastboot, recovery, normal). For each of these boot modes a separate device drive might be installed on your Windows. So check the device drive after each change of boot mode. If needed uninstall and reinstall the correct device driver.
I want to unroot my phone and I did manage to flash stock recovery.
But now I want to flash stock firmware through adb sideload.
But when I typ adb devices it does not recognize my device and when I type the sideload command, it says error: device not found.
I am using minimal adb fastboot version 1.4.2.
I already tried to use all the different kinds of drivers @ device manager
I am really out of idea's and hope someone here knows what to do.
Edit:
When I use TWRP recovery and I use sideload, adb can recognize my device (and fastboot can also recognize my device).
So only through stock recovery adb cannot recognize my device.
And I remember that USB debugging is off, I do not know if that has to do something with this?

For the stock recovery, Side load Works.
But only Side load, not "adb devices".
After you have selected Side load from stock recovery,
(Boot in stock recovery,
Select your language, -> install from usb -> yes )
Only after this, your device will show in "adb devices"
It will show as Side load device. Then Side load as usual., It will work.
P.S. - USB debugging is not checked in recovery mode.

Sorry for late reply!
I did what you said, but I get this error:
error: device '(null)' not found
And when I select install from usb -> yes, Windows notify that there is a problem with the device and cannot recognize it.
What drivers must be installed, OnePlus drivers and ADB drivers?
Does someone know how to fix it?

The problem is stock recovery that you Install does not work well in windows 10
1 Boot in bootloader install TWRP again here
2 Reboot in TWRP Recovery
3 Wipe> Advance Wipe> Select Dalvik & Cache System & Data> Swipe to Wipe
4 Reboot in TWRP Recovery Transfer OOS 4.5.8 Full Rom Zip to the device over MTP
5 Install Menu> Select OOS 4.5.8 Full Rom Zip> Swipe to Flash
6 Reboot System
Now you are in full stock OOS
If you restart now in stock recovery you will see that sideload will work
Adb sideload with stock recovery not work in Windows 10, if you use Windows 7, you'll find that it work well.
The problem is stock recovery from the official site
This OP5_recovery.img
If you are in TWRP and install OOS stock rom sideload will work in windows 10
Had driver issues to what j did was with twrp installed I transferred the Oxygenos rom to internal storage installed it from twrp and then put the OnePlus recovery back on
I have seen a lot of people using unofficial and third-party methods to root, which can result in a lot of adverse circumstances to say the least.
So I'm presenting a complete noob-friendly guide to rooting.
Prerequisites:
1. A computer ( I'm using Windows 10 but any OS would do)
2. A USB cable
3. Basic computer know-how
Part 1 (Getting computer ready)
Download sdk tools (adb and fastboot) from here
Note that in the entire guide I'm using official products.
So in Windows, download the zip and extract it in any folder.
Now download latest twrp recovery from here
The lastest version as of 7th August, 2017 is 3.1.
The downloaded file will be named as twrp-x.x.x-0-x3.img.
Now rename this as recovery.img (this will make our work easier)
Now move that file to platform-tools folder which we extracted earlier.
Also, I suggest downloading Intel USB drivers for Android from here
Part 2 (Getting Phone Ready)
Unlocking bootloader didn't format my phone but taking a backup is still important.
Now go to Settings<About Phone and click on Build until it says "You have become a developer"
Now back to main settings menu and find "Developer Options". And turn USB debugging on.
Download magisk install.zip, unistall.zip ans apk from here
Now connect your phone to PC via USB cable.
Step 3 (Rooting!!)
Now open platform-tools folder and press Shift+ right click.
Select "open command prompt here".
Now a terminal will open.
Type
Code:
adb devices
Now you will get a prompt on your phone. Accept it.
Now type
Code:
adb reboot bootloader
Your phone will automatically reboot and fastboot will come up.
Now type
Code:
fastboot oem unlock
[Alert! If you get <waiting for device> right click on start menu, select the unrecognized device and install Intel driver in it. Google for detailed instruction]
The process will start and you will get something like
(Okay ....)
(Okay....)
And type prompt. Now type
Code:
fastboot flash recovery recovery.img
Flashing will start.
When you get type prompt again, type
Code:
fastboot reboot
And when the screen switches off, hold power up+power button.
(
Code:
fastboot reboot emergency
should work but it's effect was same as
Code:
fastboot reboot
If you get something like red state... verification failed... Then it's a good news.
Wait a few seconds and then twrp will launch. I suggest swiping on the first screen
[because letv is almost dead and we can't expect any updates. Plus my bootloader was relocked in my first attempt when I didn't swipe.]
(I suggest wiping dalvik cache and cache)
Now you can just reboot your phone normally.
Now install magisk apk.
Now reboot again to recovery. (Easiest way is Update app>tree dots menu> reboot to recovery)
When twrp starts, go to install> download and find magisk zip. Swipe to install.
Reboot and you have a fully rooted phone!!

Intel drivers worked for my leeco le 1s. Ideally, Intel drivers should work for all devices.
I'll make a tutorial with screenshots on setting up the drivers whenever I get time.

There was a prompt for TWRP update and Magisk Update.
After it has started showing Orange State instead of Red State.
The phone got rebooted and all installed apps were deleted.
Xposed got uninstalled.
Playstore, Googlemaps got unistalled.
Camera is working.
Calling is working.
Now it shows Orange State.
Is it safe.
Can we bring it to red state?
As per this link
https://www.androidauthority.com/verified-boot-warnings-in-android-6-0-marshmallow-650368/
Orange warning: Your device is in an “unlocked” state. This means that your operating system can’t be checked to make sure that it’s safe to use.
Red warning: The operating system on your device has been changed or corrupted and is not safe to use. The device may not work properly and could expose your data to corruption and security risks.
Orange State seems to be a better state than red.

The process will start and you will get something like
(Okay ....)
(Okay....)
Here l select the unrecognized device and install the Intel drivers but it stuck at the "Okay,,,,Okay" prompt. Meaning that l didn't get this okay prompts and it keeps me on waiting the whole day.
Secondly, till this command l stop it and power down the phone, so after l power back on and try opening the "Application" folder, then it's not working anymore, it shuts down itself.
Please help!!

Hello everyone. Meanwhile you excuse me for imperfect English but I use translator, my English language is rusted...
I have a A2017G, I have managed to unlock the bootloader, install TWRP and SuperSu on 6.0.1 version But then I have had the nice idea to update to 7.1.1 then have put update. zip file (renamed), in SD card, turn off the terminal, enter into TWRP but it Disappear!!! Only Originale...io recovery make flash and device updated to B09.
I want to install TWRP and SuperSu and put alternative ROMs but I can't do anything! If I open PowerShell window in adb folder and command "ADB reboot bootloader", the device reboot and appear a screen where to " your devices software can't be checked for corruption, please lock the bootloader", ecc ecc, If I squeeze volume on, it will get into recovery, if I don't do anything it reboot normally.
I can not get into fastboot mode, I fail to install TWRP. What is the best way to go back? or reset everything and start again? I have tried to downgrade from Nougat to MM via SD but after about 1 minute of analysis I aborted the installation....
However the phone will work normally even without all these things but I have purchased ZTE for modding and I don't bear to have half fatto...in work the most difficult thing to be unlocking the bootloader and I do this thing...
Let me link you my ingenious, allmighty Axon 7 Companion Thread.

Your phone works normally
You don't have fastboot
You have stock recovery
If this is the case then most surely you have EDL working...
Install TWRP from EDL mode:
This is taken from Controllerboy's guide
BE SURE THAT WINDOWS SHOWS FILE NAME EXTENSIONS!
A) Flashing TWRP Recovery to your device.
Q: Why do I need TWRP?
A: TWRP is a custom recovery system. It lets your backup your system in case anything goes wrong. It also lets you flash custom ROMs and zip files containing patches like viper4android or A.R.I.S.E. (audio) and root your device via SuperSU.
0) Boot up a windows computer with a 64bits processor. Verify your Axon 7 is charged at least 75%. Temporarily disable your antivirus software to allow axon7tool to work.
1) Backup all the data of your phone's internal memory that you don't want to lose. Copy it to your PC
2) Download the axon7tool from here: http://www.filedropper.com/axon7tool-15-win64
3) Download minimal adb and fastboot from here: https://www.androidfilehost.com/?fid=457095661767103465
4) Unzip the minimal adb and fastboot file, place the folder with the files in it somewhere you can easily find it
5) Place the axon7tool exe in the same folder as adb.exe and rename it to "axon7tool.exe" (it's easier to work with that way)
6) Download the TWRP .img and .bin files from here: https://drive.google.com/open?id=0B4...nlaZU1NRldoRjA
7) Place the TWRP .img file in the same folder as "adb.exe" and "axon7tool.exe", rename it to "recovery.img"
8) Make a copy of the "recovery.img" file and name it "recovery.bin". Leave it in the same folder
9) Go to settings in your phone and go to "About Phone". Tap "Build Number" 7 times to make the Developer Options available
10) Go to "Developers options" and tick "Allow OEM unlock" and "Android Debugging"
11) Connect your Axon 7 to your PC
12) Open a command window by holding shift and right-clicking in a blank space in the folder where the "adb.exe", " axon7tool.exe", "recovery.img" and "recovery.bin" files are located. Click "Open command window here"
13) Type "adb devices" and hit enter. You should see one device with some code listed
14) Type "adb reboot edl" and hit enter. Your device will reboot to EDL mode. It appears to be off, but it is in fact in EDL mode.
15) Go to Device Manager on your pc and verify your Axon 7 is listed as "QUSB_BULK"
16) In command, type "axon7tool -r gpt boot recovery" and hit enter
17) After it is executed, your phone will reboot. Wait until it has fully booted.
18) In command, type "adb reboot edl"
19) Verify you now have 3 backup files in your ADB folder for gpt, recovery and boot. These are backup files in case something goes wrong
20) In command, type "axon7tool -w recovery"
21) Wait until it finishes
22) Your phone should reboot
23) Shut down your phone and boot it to TWRP by holding both the power and volume up button to verify you have TWRP
24) TWRP might ask you for a password. If it does, simply tap cancel. It will ask you if you want to modify system. Swipe to agree
NOTE: if you have problems connecting to your phone as QUSB_BULK, download Zadig and replace your drivers with WinUSB ones. If axon7tool doesn't recignise your device even when connected as QUSB_BULK, try killing adb.exe via task manager before retrying.
Hello and thanks for the guide.
I have tried this system... be gone everything OK up to number 16... when I type "Axon7tool -r gpt boot recovery ", the command window should be written "Failed to connect "... and yet the device is in EDL mode.
Be all right, on Device Manager be seen as "QUSB_BULK ", the cable being original, all steps 1 to 16 be ok...io no longer know what to do.

I have tried this system... be gone everything OK up to number 16... when I type "Axon7tool -r gpt boot recovery ", the command window should be written "Failed to connect "... and yet the device is in EDL mode.
Be all right, on Device Manager be seen as "QUSB_BULK ", the cable being original, all steps 1 to 16 be ok...io no longer know what to do.

Easy. Hold all 3 keys (power, vol up and down) until Device Manager refreshes (you'll see it as the list of devices contracting), and close CMD. Open it again and do step 16 again

Hello and thanks for the advice. Unfortunately it does not change anything.. I have done exactly as you say but the result does not change anything...io have connected the device, Open command window, type "adb devices ", is viewed as "Cd07b2e9 device ", I type "adb reboot EDL ", it restarts in EDL, then go to management Devices and is viewed as "QUSB_BULK ", Run command "Axon7tool-r GPT boot recovery " but it says "Failed to connect ", then I'll return to Device Manager, hold volume up & Down & Power, Icon disappears and returns after a few seconds, close window and launch command "Axon7tool-r GPT boot recovery " but still give "failed to connect "...
So, recapping: I have bootloader unlocked, I can get into EDL but PC does not see device although on Device Manager it exists...
I now launch device into the wall... problem solved.
if you really slammed it against the wall, i would love to buy the back housing and speaker grills. hopefully, you were just illustrating frustration (it is a frustrating scenario), and will reach a resolution, but if you actually did smash it, i could use some parts.

Of course I'm kidding... have just purchased this device, have a great hardware but the software does not go well for nothing. I have had a dozen phones, I changed about 60 ROMs, so for me it is not difficult to change the software...ma in this case have problems. Is it possible that I fail to solve this problem? Be a way to reset everything and start from scratch? Okay, the bootloader be unlocked but not be any other way to go back? I have seen many guides but not able to solve the problem. I fail to make flash of TWRP, fail to do downgrade to MM....io hope someone help me... thanks.
are you using a USB 2.0 or 3.0 port? it may not apply to this scenario, but with Motorola and RSD Lite, I always had to use usb 2.0 ports or it wouldnt see my device when flashing.
also, the steps @choose an username listed out are the best way to start from scratch, but obviously you have to be able to have your computer see the phone in the desired mode.
@DrakenFX has several guides in the axon 7 forums that should help once the computer sees the phone as well.
I use USB 3.0 with original cable ... but if you now tell me that maybe this is my problem, then I use USB 2.0. Thank you...
Good morning...
Nothing to do... I put the original cable on USB Port 2.0, have redone procedure from window PowerShell, on command "adb devices " Everything OK, on command "adb reboot EDL " It enters EDL mode, but then all the procedures are failed... if command "Axon7tool-R recovery GPT boot "I always get out of the inscription " Failed to connect ", it remains in EDL and I just have to reboot... I replaced the drivers with Zadig 2.3 but did not change anything... are there any other moors to make flash of TWRP? exist lthough an app that do this? I remember that for LG G3 I'll fix everything with an app...
I want to install LineageOS so I closely followed the fastboot and adb instructions on the official site. During my first (failed) attempt, there were some old Google USB and ADB things on my PC, so I deleted everything and started again with a clean slate.
I managed to make ADB work (adb devices detects my device, could authenticate the computer, all seems good there). But if I start the phone in fastboot mode, connect and run fastboot devices, I get nothing back. It doesn't give any sign of the connected device. Windows's "Devices" window lists a device called "Android", but it's under "Unspecified" and has the yellow triangle/exclamation mark on the icon.
1. Am I right to assume that this will stop me from unlocking the bootloader (if I will use the unofficial method) and flashing TWRP and a custom ROM on the device?
2. More importantly: What could be wrong, how can I make fastboot see my phone?
Many thanks for the suggestions!
hi,
first do you have latest ADB and Fastboot
then connect your device and run adb devices. check if it detect the device means from the command prompt run "adb reboot bootloader" (without quotes)
now once after device reboots to bootloader check fastboot devices it will detect now
if not then goto device manager,right click on the device and click on update driver software and choose android fastboot interface
you are done now run fatboot devices,it will detect the device
Solved!
