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
Let me know if this post belongs somewhere else.
My Mi A1 is stuck in a bootloop as a result of trying to install magisk 14.4. At the moment I can boot it into fastboot mode, but not into recovery mode. In fastboot I can execute the command
fastboot devices
that returns the hex number followed by "fastboot." However, it does not respond to any other fastboot commands, e.g.
fastboot reboot
fastboot oem device-info
I have been attempting to flash the stock rom without success as follows:
in win10 32-bit environment:
fastboot responds as above. I cannot install the MiFlash-2017-7-20 version. Windows complains. I conclude that version must be a w10 64-bit app, although it doesn't say so.
win10 64-bit
MiFlash-2017-7-20 installs and runs, but does not see the device. Apparently, the adb drivers are at fault. I have turned off signature enforcement and tried installing various versions of the adb drivers. The device manager shows them as installed, but reports that they cannot start.
Centos 7 linux
Adb drivers install. "Fastboot devices" reports correctly. All other fastboot commands fail, i.e. they hang. I tried installing the tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794 image using the linux shell script provided, but that just hung also.
Is this phone well and truly bricked at this point? Is there any other recovery available?
I think it is not hard bricked by any means. Try booting into the Quallcomm EDL and try flashing the fastboot rom with MiFlash too. You can setup a virtual environment in which the flash tool can run and the drivers can install properly.
Maybe you should boot to other partition (A or B)
Just fastboot then try boot to other partition, hope it works

As he said, he can't execute fastboot commands so that isn't a option.
@yuoip
1. You say that "fastboot devices" works, but "fastboot reboot" not. What error do you receive? Could you paste full log?
2. Sometimes drivers in Windows must be installed manually - open device manager, find unknown device, choose from list and find and choose "android fastboot" or "android adb" device depending on the mode you're in. If you have installed fastboot device before, you should be good to go. Otherwise you'll need to download minimal adb package (https://freeandroidroot.com/download-minimal-adb-and-fastboot-all-versions/), or Google development kit (much larger).
3. stock recovery mode is started by pressing "power button + volume up", once "no command" screen appears, press shortly "power button + volume up" to show the menu.
4. please post full log of command "adb devices" as well
Hola guys. I got mostly the same issue here. While I still can use adb comand while on fastboot. But i can't flash stock rom using mi flash.. i mean after the done notice my phone still stuck and wont reboot. Like the flash doesnt apply to the phone. I wonder what was wrong

Unpack ROM image, extract directory, open cmd, run "flash_all_except_storage.bat" (you might want to remove command "fastboot %* oem lock" from the end of bat first), check/show log.
The easiest thing that worked for me in a similar situation is going into stock recovery and factory resetting the device. I had tried pretty much everything before this and my device was still dead for 1 and a half days before i hit upon this idea without any guides and it worked!!
Do this to get into recovery mode:
1. Power off your phone
2. Press power button and volume up button at the same time
3. You will get "No command" Screen with Android robot with exclamation mark
4. Press power button (don't release) then press volume up button..
5. You will enter into recovery...
The phone may just reboot normally the 1st time you try it as it requires some practice to get it right, but keep trying..
Hope this helps

1. I tried this method to boot into EDL with no luck. Is there any other way?
C:\Downloads\xiaomi mi a1 root>adb reboot edl
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: device '(null)' not found
2. On my win10 32-bit installation I am able to run MiFlash-2017045. It reports the device. I attempted to flash this image:
tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794
It completed and reported "success" however it did so in only 7 seconds, so it must not actually have succeeded. In any case the phone still will not boot.
3. However, I distrust MiFlash 20170425 because it comes from an androidmtk.com site and the processor is Qualcomm, not Mediatek. So I attempted to install MiFlash2017-07-20. However, that program will not install on my win10 32-bit installation. There is a Windows msg saying it cannot be installed, but does not give a reason. I suspect it is a 64-bit program. So, I installed MiFlash2017-7-20 in a win 10 64-bit installation. The program does run, but it does not see the device. I suspect that the adb drivers do not install correctly. I did turn off signature enforcement and the drivers appear to install, but the device manager reports that the drive cannot start.
The tissot images include bourne shell scripts to install, so I installed the adb drivers on my Centos box. Fastboot reports the device, but just as in win10 no other fastboot commands work. So, even though I did try to execute the install_all.sh script, it just hung on the first "fastboot getvar product" command.
So, I do not have a way to flash the stock rom.

1. All fastboot commands, other than "fastboot devices" just hang on "<waiting for device>" with no error message in the linux environment. In the win10 environment they timeout after a few seconds with a message like this:

finished. total time: 7.000s
2. I had already installed adb-setup-1.43.exe, but I ran it again anyway. Same result.
3. The device will not boot into recovery mode. Pressing power and volume up brings it the "no command" screen with the supine robot image.
4. C:\Downloads\xiaomi mi a1 root>adb devices

Use fastboot commands manually. Mi flash tool is very buggy. Many time it doesn't work.

Did the command:
C:\Downloads\xiaomi mi a1 root\tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794\tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794\tissot_images_7.8.23_7.1>fastboot getvar product 2>&1 | findstr /r /c:"^product: *tissot" ||
"Missmatching image and device"
So this is a little interesting. However, I don't think that the image is actually the wrong one, but that the script cannot get the device info since both "fastboot getvar product" and "fastboot oem device-info" fail on a timeout.

When I do that it just keeps going back to the "no command" screen. I think the recovery image is either damaged or gone.

1. & 2. It sounds like you don't have installed fastboot drivers (install them manually via device manager) or phone isn't connected in fastboot mode (make sure there is a picture with fastboot written on the phone).
3. this IS the recovery mode, just press power + volume up again to show the menu
4. you won't see ADB devices in fastboot or recovery mode, unless you enable ADB sideload from recovery
Device Manager shows:

Wrong drivers then, it should say Android bootloader interface. Reinstall them correctly.
1. I did the manual install, but I don't see anything labeled "fastboot driver."
Device manager now reports:
Android Phone
Android ADB Interface
Android Bootloader Interface
Android Bootloader Interface
Android Composite ADB Interface
However, all these entries have a warning symbol on them. The Device status for each is:
This device cannot start. (Code 10)
The specified request is not a valid operation for the target device.
Is one of these the fastboot driver? Apparently not, since the behavior of the fastboot command hasn't changed.
When I try using the fastboot command the A1 shows "Fastboot" with the rabbit character and the sick robot.
I should mention that in the Centos environment I have installed the android-tools package, which include adb and fastboot drivers and tools. The behavior of the fastboot command there is the same.
So, this leads me to believe that the problem is the A1, not the windows or linux environment, but I don't know enough to know for sure. Also, I would assume that if the fastboot drivers were not installed, the command "fastboot devices" would fail, but it doesn't.
3. At the "no command screen" if I do press and hold the power button and then the vol. up button it boots right back into the "no command" screen. There is no menu.
4. With no recovery menu I can't set any options.
Uninstall/remove everything with android name in it, disconnect phone, reconnect phone in fastboot mode. Make sure that there is only one item under Android Phone - Android Bootloader Interface. You should not see 4 devices - do you have Android emulator running or anything else connected?
When in recovery, do not hold power + volume up, just press it briefly. Sometimes it takes few tries to show the menu, but I can assure you that it's there.
Yes! You're right. The recovery menu is indeed there. I didn't know that it had to be a short press to bring it up. Thanks.
Device manager now shows only one "Android Bootloader Interface" entry. I am not running any emulator.
So now what do I do? Do I need to flash the tissot... image? The fastboot command still behaves as before.
Quick Google search suggests to avoid using USB 3.0 ports. So..maybe try another ports on your PC..?
I can't get into fast boot mode on my US996. Adb connects just fine and shows the device with "adb devices" command.
However, fastboot command just sits there with a "waiting for device" message, until I CTRL-C out of it.
What can I be doing wrong??

Post moved to another forum and was told it really belongs here; so I'm putting it back:
I've read a ton of threads on the problem of TWRP failing flash, but no help. Maybe I've missed something??
Enter FB mode on the phone and then on PC I Issue "fastboot flash twrp.img", the DOS window reports everything OK; I pull the battery but in no way can I get into TWRP it just boots regularly no matter what buttons I hold down in any sequence.
studied the thread attached intently, but no help. My phone is a US996 (unbranded) and I unlocked it (successfully) via LG's procedure.
Ideas, anyone??

Boowho??
P.S. Anyone have the stock boot image for this phone? Magisk needs it to patch and then flash. I've been unable to find it and yes, I have searched this forum
Last week i received a notification the 8.1 Oreo update was available for my Moto g4 Plus.
Downloaded the package and hit the install button. My moto restarted in order to perform the installation.
However, since i had TWRP installed and thus bootloader unlocked, the phone restarted in recovery mode.
Downloaded a TWRP 8.1 rom and installed it without a problem.
Unfotunately everytime I restart my Moto it starts up in fastboot mode.
Bootloader log shows: Fastboot Reason: reboot mode set to fastboot
From bootloader I can start the Android OS, but i wan't to get rid of this reboot mode
I tried tools like "Android Multi Tool" and "Free ReiBoot for Android" but this reboot mode can not be cleared.
Anyone encountered this problem and how did you fix it.
Thanks in advance
Try this:
Reboot your device to the bootloader.
Connect your device to your computer and open an ADB terminal on your computer.
In the ADB terminal, type 'fastboot devices' without quotes. Press Enter - your device should respond with its serial number.
If so, then type 'fastboot oem fb_mode_clear' without quotes. Press Enter, then reboot your device.
That fb_mode_clear command seems to clear a flag that keeps your device booting into fastboot (usually for OTA updates).
I have Tried that option as i found it as one of the possible solutions for this issue.
the clear_fb unfortunately does not remove the fastboot mode on my moto.

echo92. Thanks. Works like a charm. Issue fixed.
Weird: I was just using it normally, it switched off and now it stays stuck on the Google logo; when entering recovery mode, I get TWRP"s splash screen and it stays there, so I cannot even recover.
Suggestions please??
Note 1: I'm pretty bad with this kind of stuff, need step-by-step instructions.
Note 2: rom is AOSP 7.1.2 but I guess is irrelevant, as even TWRP does not load.
Thanks in advance!!
Can you fastboot boot the TWRP recovery?
Hmmm dont know exactly what that means sorry; I mean I havent tried connecting it to the laptop and using thr ADB toolkit, but I can reset via Power+VolDown to the bootloader menu (? the android layind down and giving the option to StartSystem/ SwitchOff/ Restart/ RecoveryMode), and choosing RecoveyMode it tries to launch TWRP (it even shows the logo) but stays there on the splashscreen, doesn't quite manage to give me the TWRP menus
Someone?

let's see... I set in recovery mode, connect to the PC (does not recognise it), and with "fastboot boot twrp.img" it just sends/writes the file, the tab shows the Google logo with open lock, and then tries to launch Twrp, but as before, it just get stuck in the splashscreen "TeamWin Recovery Project 3.3.1.0" , so just the same.
Command "fastboot flash boot twrp.img" the same
Command "fastboot flash recovery twrp.img" the same
Command "adb devices" returns the list empty
Command "adb reboot recovery" returns "error: no devices / emulators found"
Command "fastboot oem unlock" returns "(bootloader) bootloader is already unlocked"
I tried running a tool called FirstAid (https://forum.xda-developers.com/devdb/project/dl/?id=16684) but does nothing for me

Video and photos of the issue (device, not adb)
video: https://photos.app.goo.gl/GrFrmQhbyQeHVFZN7
Well, looking at your video it seems that there is no bootable ROM installed and also the recovery (for what ever reason) has some issues to start.
The fact, that you are able to boot into bootloader shows that at least it's not completely bricked ... but there's still the chance that the flash memory has some issues.
I would connect the device via usb with a PC and try to do a
fastboot boot <twrp-3.3.1-grouper.img>
to whether in that case the recovery is booting.
If this is successful, the next step would be re-flashing the recovery into the recovery partition and booing into recovery mode from the bootloader.
If this is successful, too, wiping and flashing a new ROM would be the last step.
