[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.

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".

Bootloop after fingerprint sensor and ROM died

Hello,
problem above, maybe it's a hardware malfunction which would be awful.
I tried:
- whipe everything in the CyanogenRecoveryMenu
- sideload via Minimal ADB / Fastboot
- a lot more commands and helps on this site and on the internet (push,
Details:
- fingerprinter died, then the phone always crashed with blue and green flashing lights on the screen and now a bootloop
- "stock" CyanogenOS installed, but no TWRP
- the phone gets detected by my computer (sound)
- i don't remember if usb debugging is enabled (probably not)
- the command "adb devices" shows my phone when its in ADB mode (recovery menu)
- i sometimes get the error "error:closed" on my computer
Thank you for any help

Did you also tried factory reset already?
If you have adb access you can only try to get bootloader unlocked which wipes all if not happened yet. Then you can try installing twrp and another rom and see if boot is OK.
If your bootloader is still locked go to service center if you have warranty!

Thanks for a reply,
After a full reset I have downloaded a twrp.img file for my device
I tried:
- command "fastboot devices" while in fastboot-mode (I pressed reboot to bootloader in the recovery menu to get there)
-> no device detected despite a sound after connecting
- command "fastboot flash twrp.img" -> "waiting for device" without any further reaction
My device is only detected in ADB mode, not in fastboot mode, how can I change that? I must unlock the boot loader in fastboot mode right?

Did you have actually drivers installed for fastboot? See guides like this http://forum.xda-developers.com/zuk-z1/general/guide-how-to-unlock-root-install-twrp-t3394037
Also qfil method can help http://www.androidbrick.com/lenovo-zuk-phones-qfil-roms-unbrick-guide/
But consider service center in case of warranty.

same problem. fingerprint died. then after a empty battery shutdown i face bootloop. but hopefully i have TWRP installed and i could recover my data. but i dont know how to access factory reset menue or install another fresh rom

re-locking boot loader & restore

How can I relock the boot loader and restore my Stylo 2 to factory default? Provider is T-mobile.

fastboot flash oem lock.
Note however if you used twrp this will brick your device unless you flash the original recovery first. Provided you got the kdz or LG bridge you should be able to just lock put in download mode and use the repair recovery option.I'm not responsible if you brick your device. Good luck

I had used LG Bridge to reflash my phone so I believe that I have original recovery on the phone. How can I verify?

When I enter fastboot flash oem lock I get < waiting for device> on my terminal screen and thats it?

Once you have the phone wiped completely back to default (including recovery) with the LG tools. Enable developer mode, and then enable USB debugging. While it is plugged into your PC navigate to the folder where you have the ADB applications in CMD or add the location to your Environment variables. The latter will allow you to launch ADB/fastboot commands from any location in CMD. I definitely suggest this. With your phone connected run "adb devices" to make sure that it sees your device. Then run "adb reboot-bootloader" to reboot into the bootloader. While on that screen run the command "fastboot flashing lock_critical". It should prompt OKAY then give the time it took and also that all of the user data was deleted. Then finish up by typing "fastboot reboot". That will put the phone back into a normal mode. Boom, you are done.

Help
When I use the fastboot oem lock, at the moment when I power on the phone in the screen appears the text "Your device has failed a routine safety check and will not boot.
This may be a temporary problem.If this message occurs rerepeatedly, visit this link on another device and refer to the Red case: g.co/ABH
I have two days looking for the solution, and I didn't found anything

Fastboot doesn't detect my phone, please help

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!

Cannot go into the bootloader mode on my Galaxy tab SM-T285

Currently, I am trying to unlock bootloader using adb.
I installed adb and fastboot and checked everything until the CMD shows my device correctly.
And right after I type
"adb reboot bootloader"
my tablet just restart and does not go into the bootloader mode.
I also tried it manually, by pressing home+up+power button, but it also perform restart and no bootloader mode.
Does anyone knows why?
I checked all the settings in developer mode and cannot figure out why.

You can't unlock the bootloader with adb only with fastboot which doesn't work on Samsung. To unlock the bootloader on Samsung you have to enable OEM unlocking in developer options. Also Samsung doesn't have bootloader mode but instead they have Download mode which you can use tools like Odin or SmartSwitch to flash files. To get into Download mode use the command adb reboot download or use the button combination power + volumn down + home.
