[SOLVED] Z1 not showing up in Linux ADB devices

hi,
trying to flash the breadcrust recovery using my linux pc, but the Z1 doesn't appear in the list of devices when running adb devices. Image attached. Normally I would get a request to accept the RSA key for a trusted pc when enabling usb debug. But I don't get this option.
- Adb tools are loaded and working on my linux laptop
- My nexus 7 responds to ADB devices and shows up ok
- tried on wifes windows laptop with adb/sdk tools loaded and no joy there too
- i have developer USB debug options enabled, i've tripple checked this
could it be the cable? I'm using the one which came with the phone, so that should be ok?!!
cheers
SOLUTION - I ran this One Plus Two script modified with the Z1 device ID and now I can see my device in adb devices and interact with it. I get the SHA screen to allow access and can run commands from linux terminal. YAY!
See the attachments for script.

I think it´s a driver fault. Did u install them in windows?

im using linux, i dont get any rsa pop up confirmation either!

and that was the reason, why i installed windows last night. as long you dont get rsa pop up, the device will not listed (i think so)

But u said, that u tried ur wifes Windows notebook. Did u install the drivers there?

ADB doesn't work for me, too. I work around this problem by booting into recovery (simultaneously press Vol+ and Vol- and Power until phone vibrates) and choose "Boot to bootloader" from there. After rooting I installed "Power Toggles" from Play Store and use the toggle to reboot to recovery or bootloader.
By the way, when I boot into recovery, I'm able to ADB sideload. So I don't think there's a driver issue.

Good tip - I'll give it a go.
My nexus 7 works as expected on all PCs and laptops Linux/windows so it must be the phone

ok some progress.....
got the trusted device RSA screen to appear on my wifes windows pc. i could then run adb devices and see the device.
I could run adb reboot bootloader, but the device doesn't boot into fastboot, just reboots as normal!
I could also hold down up/down volume buttons and get into the bootloader, but again the device isn't picked by any fastboot oem checks for unlocking!!
arrrgh!!!

You'll have to add -i switch followed by the device ID to your fastboot command. I don't have it at hand, so just read the TWRP thread.

ok! Some progress...ish.
running "adb reboot bootloader"command in windows worked when I switched Cyanogen recovery updates off in developer options. The Z1 reboots into bootloader.
Running "fastboot -i 0x2b4c oem get-device-info" returns nothing just "....."
So I tried "fastboot -i 0x2b4c oem unlock" an error returns cannot unlock use command "fastboot -i 0x2b4c oem unlock-go" which works. The phone wipes data and reboots back into OS.
I re-enable the developer options and adb debug. and reboot into bootloader
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.
weird!

Your commands are simply wrong, thats why they don´t work.
It is:
fastboot -i 0x2b4c oem device-info
fastboot -i 0x2b4c oem unlock-go
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.

Flashing does NOT work on the international version, you have to boot into it directly from fastboot.
fastboot -i 0x2b4c boot z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img
Should be correct instead of the flash command.

What made the change? I was able to see the RSA screen only once, but after device restored to defaults I can't get it back. same drivers installed, and it appears in the device manager.

I honestly don't know, it just worked after many attempts. I read somewhere about USB 3 ports with Linux so might be the same for windows?

It's an USB 3.0 issue. Plug the phone into an USB 2.0 port, or an USB 2.0 hub plugged into an USB 3.0 port and it will magically start working. God knows why this is the case...
Ironically, fastboot works fine even on USB 3.0...

For to be able to boot (not flash) the TWRP recovery you shouldn't need to unlock bootloader. Am I right?

Booting should work.
At least it worked fine on other fastboot capable devices I've had in the past.

Okay, I have found out that it is impossible to boot from TWRP as log as the bootloader is locked. It just took me 2 hours to setup my phone again after unlock.

Have a look at this thread, I am going to give it a try later.
http://forum.xda-developers.com/showthread.php?t=2408802

This did the trick on Linux (Ubuntu):
- run on terminal "sudo gedit ~/.android/adb_usb.ini"
- put "0x2b4c" in
- run on terminal "adb kill-server" and "adb start-server"
And run the fastboot commands with "sudo".

Windows 10 laptop can't detect softbricked Nexus 4, TWRP, no OS

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.

A2017g can't reboot to bootloader

So I've just received my axon 7 a2017g. It came with b06 installed. I'm trying to unlock boot loader without success. Can't get to edl mode. In cmd the device is unauthorized though I've enabled oem unlock and sub debugging. Installed the drivers from sub debugging. I have Windows 10 64 bit. I get to recovery with volume up plus power I select to reboot to bootloader with no success. It only restarts. Tried also with b10 and b08.
Any suggestions ?

Why bootloader? Isn't there a way to do it via EDL (from system, do adb reboot edl)? On Controllerboy's guide maybe? Maybe you think that the device doesn't get to EDL because it seems like it's totally powered off. Just try again.
As of fastboot, it was removed on Nougat, not sure if they removed it before though

Did not understand you. Where in system to do and reboot?
The phone is turned onand connected the the pc and I've enabled oem unlock and usb debugging.
The device won't boot to edl after I enter adb reboot edl. So I tried in recovery screen to get to the bootloader menu but pressing reboot loader it just restarts

You have to have adb and fastboot installed. Run "adb reboot edl" from your computer while the phone is on, it should ask you if you want ADB to be allowed to do stuff, then poof. Go to the Device manager and check that there's a Qualcomm HS-USB QDLoader 9008 under Ports (COM&LPT)

Unplug the phone, turn it off. Hold only the 2 volume buttons (DON'T TOUCH POWER) and insert the USB-C (plugged to the PC in the other end ofc) while holding the two volume buttons. then check device manager
This should get you to EDL

Okay after you do that last thing you should get to EDL. Download Zadig, uninstall the Qualcomm QDLoader drivers and tick Delete driver software too. Then go to Zadig and install the driver. After that hold the 3 buttons (pwr, vol) until the led flashes or your PC makes a sound, wait 5 seconds, and you'll be able to run axon7tool.exe -r gpt boot recovery

In zadig's post he says they G models should edl only by the command. But I did as you said with the volume buttons. I run axon7tool in command But it says no device found

Thinking about it it's not that weird, I think you're not getting the Zadig part. Did you install the driver through Zadig? How's the device reported aa when on EDL? If you installed the driver properly it should be listed as QUSB_BULK under USB something

Sure I'm not doing something right.
First I did not have Qualcomm drivers installed
I'm in edl with volume buttons and sub. open zadig and install wcid.
From here I did not get it. Hold all buttons vol÷power?

Like this ?
"adb devices" command:
List of devices attached
* daemon not running. starting it now at tcp:5037 *
* daemon started successfully *
xxxxx unauthorized
When enabling USB debugging then with USB cable connected, there is a popup in your phone, asking to authorize
your phone (with digital signature etc..). You need then to authorize it. Afterwards, your phone will be recognized
with 'adb devices" output as :
List of devices attached
* daemon not running. starting it now at tcp:5037 *
* daemon started successfully *
xxxxx device
xxxxx is your device id. You must have status "device" and not "unauthorized"

I have oconnection options like charging, mpt etc.

And why it doesn't reboot to bootloader from recovery menu?
I really think something is wrong with the device.
Where can I find a2017g b03? In every post the link to zte's website that only have b11 and nougat.

Please check periodically USB debugging option. I encountered similar problem as your, and before the popup that confirms USB debugging
for the phone, the option is set back to disabled. So maybe you have to check again this option, unplug and replug the phone, choose option MTP,
this should help to have the confirmation popup. Anyhow you must have to reach status "device" which means your phone is able to connect using ADB.
For A2017G B03, it is not necessary, B11 is OK for unlock, TWRP or root using the current guide.
However if you really need it (A2017G B03, B06, B09):
https://forum.xda-developers.com/showpost.php?p=68873485&postcount=3

I suspect that my laptop is causing me trouble as also my g5 will not prompt me with authorization.
I'm gonna use a different laptop without any drivers installed. Can someone tell me all the drivers needed for the a2017g in chronological order so there won't be any conflicts?
In other tutorials they don't mention Qualcomm's driver but in othrrs they are needed.
This phone makes me so frustrated.
So please a step by step from new how to connect to adb on a total new pc. From there I hope I'll manage.
Thanks to all who replied. It's much appreciated.

Here the same problem with an A2017G model. Phone worked with the latest LineageOS, was rooted and got an unlocked bootloader, and with flashing to the the new B04 update phones ends up in a loop.
I can get into the stock recovery and when i choose "reboot system now" i get a screen wich tells you to lock your bootloader.
In recovery a can also choose "apply update from adb" or "apply update from sd card". With the first option i can flash a rom but at 25-30% adb ends up with an error.
With the second option i get a message "Sorry, can`t sdcard upgrade", and tryed several sd cards.
Phone will NOT boot into Android so i can`t change USB debgugging or something.
I can get in EDL mode and after "axon7tool -r gpt boot recovery" in adb the phone reboots with no errors and gets in a loop again. Grrrrr..... Very frustrating with a non working phone!

The command "axon7tool -r gpt boot recovery" only backups your boot and recovery (-r = read, so of course only files *-backup.bin are created inside your PC directory, no change to the phone).
Since you have stock recovery, did you apply the full ROM A2017G-N-B04 (australian) from here:

Cannot root or unlock Bootloader

Hi,
I just bought Mi A1.
Now, I wanted to install oreo.
So I was trying to root and install twrp.
Now I'm no expert, I just follow the provided steps and have been successful with past devices.
Note :
1) Developer enabled
2) oem unlocking enabled
3) usb debugging enabled
So I'm using this https://forum.xda-developers.com/mi...l-one-driversunlocktwrpfactory-t3695256/page2
But, there are two issues :
1) When I click on Reboot in fastboot/bootloader mode , it shows this in command prompt : http://prntscr.com/i2sn1o
and in the app, it automatically disconnects from the device http://prntscr.com/i2sncw
2) While this is happening and I leave my device, it automatically goes out from fastboot to power off charging mode.
I tried on another pc too, and followed the steps according to video, still no luck.
And I tried manual methods too, like https://www.youtube.com/watch?v=tRcYUMBgvaI
no luck there either.
Please help.

your adb driver is not installed correctly i guess, happened to me too.
try "adb devices" and will show no devices, if this happen, is the adb driver issue.
this fixed for me.

I don't know if there is issue with driver. Because during installation there was no error.
Also, when I command "adb devices" it shows me a device as number.
So it is able to connect to the device then right?

You must install adb drivers AND fastboot drivers separately. I always had to install them manually via device manager. If your phone reboots from fastboot mode automatically, I'm 99% sure that you do not have drivers installed correctly.

Fastboot not working

So i decided to root my A1. But fastboot isn't working for me.
Tried with previous adb files.
Adb works properly.
But when device is rebooted into fastboot mode. Fastboot isn't and to talk to it.
Updated adb and fastboot (sdk tools and even in AIO tool)
Just adb works.
Reboot to fastboot and my device is not detected.
Disabled driver signature enforcement in windows 10
OEM unlocking allowed.
Usb debugging on.
Tried multiple times.
Nothing seems to work.
Maybe driver problem but since adb works i don't think that's the problem and i have installed it again from AIO Toolkit.

Try different usb cable or usb 2.0 port

I had similar issue, fastboot was detected but haven't been able to do any command. So when the phone was powered on with selected usb to transfer files, in device manager the phone was listed as "Android phone - Android Composite ADB Interface", I updated the driver to "ADB Interface", rebooted in bootloader and was able to communicate through fastboot.

Adb is working fine. File transfer is working fine. Charging is working fine.

So i decided to root my A1. But fastboot isn't working for me.
Tried with previous adb files.
Adb works properly.
But when device is rebooted into fastboot mode. Fastboot isn't and to talk to it.
Updated adb and fastboot (sdk tools and even in AIO tool)
Just adb works.
Reboot to fastboot and my device is not detected.
Disabled driver signature enforcement in windows 10
OEM unlocking allowed.
Usb debugging on.
Tried multiple times.
Nothing seems to work.
Maybe driver problem but since adb works i don't think that's the problem and i have installed it again from AIO Toolkit.

I hope drivers are up to date.

Did u tested this? Reboot to fastboot mod and connect mobile to pc. then right click my computer then device manager. Then check for A1 port. Update /install driver Automatically from internet. May be it will help , may be not.

ADB drivers are different than fastboot. If you can detect with ADB and not fastboot, I would suspect you have a driver problem. Boot into fastboot, then check device manager for your device. It might not have any drivers installed and be an unrecognized device, or it could have incorrect drivers installed. My device needed fastboot drivers, I had the same problem as you.

Thanks all of you. Fastboot driver was the issue.
