phone doesn't boot (can only get to fastboot USB menu)

i can only access the white screen when i chose bootloader>recovery i get the /!\ sign.
i installed the USB driver and i was able to use only the "fastboot" commends. adb commend didn't work. when i type fastboot devices i get the serial no. of the device.
when i use the adb devices commend i get: "List of devices attached" and an empty line.
is it possible to fix this phone? thanx in advance.

adb only works within android since it's a debugger if I'm not mistaken. Try using fastboot to flash the system images of the stock rom back to their respective partitions. (ie. fastboot flash system system.img; fastboot flash boot boot.img; etc.)
You must be unlocked for that to work however.

problem solved
after almost 10 hours of research the solution was really easy.
1.download "recovery-RA-nexus-v1.6.2.img" and fastboot it using this commend:
fastboot-windows flash recovery recovery-RA-nexus-v1.6.2.img
2.flash a rom from SD card and everything should work fine

[Q] adb devices doesn't recognize n1

Been trying to root N1(FRG83) without unlocking bootloader. Downloaded android-sdk to c: drive and downloaded usb driver.
When I boot the N1 into fastboot mode and type fastboot from the cmd prompt on the computer it sees the phone and gives me the serial (HT****)
When I try the same thing from ADB (ADB devices) it doesn't recognize the phone. I just get a blank line and go back to the command prompt. I've tried this on 2 machines (1 Vista the other Windows 7) and get the same results.
The frustrating thing is that I actually had the phone recognized with the ADB devices command when I first set it up but got called away from the computer and never had a chance to run the rooting routine.
Anybody out there solved this problem?? All help appreciated.
Thanks.

download and install the sdks and nexus ine drivers manually.

thanks but no luck
Downloaded drivers as you suggested but no luck. Also tried reinstalling sdk. Debugging is on, Java is installed, I'm out of ideas for the moment.

Del everything...restart your pc, and download the drivers and sdk..it'll take a few more mins.

When this happened to me, I restarted my PC and it worked.

If I recall correctly, adb won't work while the phone is in fastboot mode - and that fact that your fastboot commands work fine indicates that it shouldn't be a driver issue. Make sure you're running the adb commands when your phone is actually booted (at least to recovery).

If the phone is recognized by the computer via usb, but the adb does not see the phone connected, you just may need to simply delete and reinstall the latest USB driver that is offered.

There is actually an issue with Nexus One's where the adb composite interface doesn't work. It seems related to the issue with the broadcom driver and the mac address starting with 38.
See here - http://code.google.com/p/android/issues/detail?id=9437 - for more info.
I have now upgraded to frg83 and it works fine.

This. If you're running ADB in fastboot, you'll get nowhere.

windows 10 and adb problem

OK, just got my nexus 6 yesterday, and said goodbye to Samsung..
first, plugged my phone into my windows 10 machine, and it instantly showed up in windows explorer, and was able to see all the directories on my phone, so that was good.
I then followed the instructions for installing the ADB/Fastboot installation stuff from here,
http://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
Opened the command prompt, typed in these commands, cd Desktop/android-sdk-windows/platform-tools
adb version, and adb version showed up just fine.
Turned off my phone, held down volume and power and entered fastboot mode, but after typing the proper commands, my phone serial number doesnt show up..
I have enabled developer mode, turned on USB debugging, enabled OEM unlock, but still no serial number shows up.
I'm not a rookie, and understand how to use ADB, but I am afraid that windows 10 is the issue..
Anyone have any suggestions?
Thanks for your input:good:
Mod Edit:
Solution found and thread closed at OPs request

You can't use adb in fastboot mode. You can only use fastboot in fastboot mode. Adb only works in android or recovery

thanks, I got it sorted out by installing this..

OnePlus3t bricked can only boot into fastboot, however my ADB driver no longer works

I have ran into a bit of an odd problem due to me messing up a root and then messing my phone up even more while trying to fix it.
my phone is fully bricked and only boots into fastboot mode. i tried to fix it with the one-plus fixer (idk its official name) but i got an error 7. I now need to re flash an older version of TWRP and try a diffrent method but i cant as my phone no longer is recognized in fastboot using the ADB tool. I have the USB driver installed on Windows. On Linux i ran the .sh script as root and it still doesn't work.
I have both Ubuntu and Windows installed on my PC so i can do whatever you suggest me to do regardless of the os.
Thank you to anyone that can help in advanced

This is not a hardbrick; a hard one wouldn't boot at all and give no sign of life (except when plugged to PC).
Try an unbrick tool to revert to official OOS. On Windows 7+ remember to disable signed driver enforcement.

You mention fastboot and adb. Which one are you using?
Just to make sure: While in the bootloader (fastboot mode), adb does not work. You have to use the fastboot commands. Installing TWRP would be:
Code:
fastboot flash recovery <name-of-img-file>
If that's what you're already trying, just ignore this post.

I want to be able to do that but if i do adb devices it no longer finds my phone

I want to be able to do that but if i do "adb devices" in the cmd/terminal it no longer finds my phone. so my goal is to be able to execute that command. However, i may be mistaken that it doesnt need to find my phone i can just execute that command

Ive done this but it didnt fix my phone.

Like I said, the adb commands won't work while in the booloader (that's why it's called fastboot mode). You need to use fastboot commands... The equivalent command would be:
Code:
fastboot devices

I had the same issues with md5, all you have to do is try a different USB port. I suggest the ones on your motherboard if you're on a PC. Then run the tool as administrator. I hope this helps, good luck!
P.S if it still doesn't work, try a different PC, I'm 100% sure it'll work

As Didgeridoohan touched upon, adb and fastboot (while related) are different. They have different requirements and applications.
adb won't work while the device is in fastboot mode. Conversely, when the device is able to use adb, fastboot commands won't work.
adb: only works booted to OS or alternately in TWRP. Debugging must be enabled
fastboot: only works in bootloader-fastboot mode. Debugging is not required to be enabled.
For flashing TWRP, it's fastboot that you need. Well, there is a way to do it with adb, but fastboot is by far the more common way.
When in fastboot mode, adb command won't work, and there fore it is completely expected that "adb devices" yields not response. Try "fastboot devices" (no quotes) and if you get the phone's ID in response, you are in business.

I've had this happen to me when I've triggered dm-verity. Instead of getting the dm-verity warning display the phone would simply boot straight back to fastboot.
My solution was to:
- flash the latest TWRP using
Code:
fastboot flash recovery <recovery file. img>
- reboot into recovery (use the volume keys on the phone to select recovery and then press the power key)
-flash the full stock image I was using before the problem started
This would clean up any changes made to the boot and system images and allow me to boot the system normally.
Note: because this leaves you with a stock kernel you'll end up with the stock recovery after you boot the system.

boot your PC into Ubuntu and install adb/fastboot (tons of guides available off the 'net). then boot your 3t to dl mode and connect it to your PC. as mentioned already "fastboot devices" should list your 3t and you should now be able to flash to your heart's content. no need for drivers, unlike under Windows. i have a bootable linux usb drive primarily for this reason. curious what script you're trying to run though..

Question fastboot devices not showing

When I open PowerShell and run the command "fastboot devices" my phone isn't getting detected. My phone is connected to my PC, I've installed platform tools & adb as well as the correct ROM. I'm pretty new to rooting so I'm not sure what's going on. I don't have a SIM Card so that might be the issue, but I'm trying to find a root guide that doesn't require sim.
What I've installed;
Latest USB Driver (MTP USB Device)
Latest ADB/Fastboot from android.com/studio/releases/platform-tools
Installed Fastboot ROM MIUI V13.0.6.0.SKDMIXM Stable from https://xiaomirom.com/en/rom/xiaomi.../#download-xiaomi-11t-pro-stable-fastboot-rom

Maybe you summarized the command in your statement but with power shell the command is "./fastboot devices"
Do you see the device icon in the taskbar?

Yeah i see the icon on my taskbar. Just tried running it via "./fastboot devices" and no devices show up. I haven't unlocked the bootloader yet (haven't enabled Mi Unlock status) yet is that maybe the issue? If so, is there a way to root without the need of a sim card?

You generally shouldn't need a SIM card to use ADB or fastboot commands.
Are you sure you have the correct drivers installed? Does the device appear under adb devices when in Android?

How do i check that I have the correct drivers installed? I ran adb devices and it showed my device 3d37ace2 device was connected.
EDIT: Here's how I enter into fastboot and excute commands;
- Plug in phone into PC and wait for icon to show up on taskbar
- Open Powershell in platform-tools folder
- Power off phone and enter fastboot (hold down power button+vol down)
- Once Fastboot text shows up on my phone I run the command "fastboot devices" in powershell

This looks like a good place to start. It's possible you have a generic ADB driver installed and may need a device specific one.

Just reinstalled the latest ADB/Fastboot from https://androidmtk.com/download-15-seconds-adb-installer and still have the same issue. I also installed Xiaomi AB/Fastboot Tools to check if it can identify my device and it does.
Running adb shell in cmd prompt outputs:
Code:
C:\Users\Whale>adb shell
* daemon not running; starting now at tcp:5037
* daemon started successfully
vili:/ $
But once it's in fastboot it responds with:
Code:
C:\Users\Whale>adb shell
adb.exe: no devices/emulators found
Same for Powershell:
Code:
PS C:\Users\Whale\Downloads\11t pro\platform-tools> adb devices
List of devices attached
3d37ace2 device
PS C:\Users\Whale\Downloads\11t pro\platform-tools> fastboot devices

List of devices attached
PS C:\Users\Whale\Downloads\11t pro\platform-tools> fastboot devices
PS C:\Users\Whale\Downloads\11t pro\platform-tools> ./fastboot devices
Currently, when my phone is turned on (not in fastboot), my device is detected as 3d37ace2 (codename: vili), but as soon as it goes to Fastboot, it no longer can detect the device.

ADB commands won't work in fastboot and vice versa. When your device is in Android or recovery, you can use ADB commands, but when it's in bootloader mode, you have to use fastboot commands. ADB shell won't do anything for you in fastboot because there's no kernel running, much less a shell.
Since your device isn't appearing under fastboot devices it's most likely a driver issue. You need two separate drivers; the ADB driver is not device specific, but the bootloader driver is.
Case in point: This is what appears when my Pixel 5 is connected while booted into Android:
When I reboot to bootloader, this is what I see:
So, this is what I suggest:
Reboot to bootloader, connect to your PC, and look at Device Manager to see if anything comes up as unrecognized. Make sure it's the right device by unplugging the USB cable; it should disappear. You'll then need to update the driver, and point it to the the Xiaomi driver folder.

Yep. I don't know how it works on Xiaomi devices but try fastboot flashing unlock
Unlocking your bootloader will wipe data, so if you need to back anything up, do that first.

Enter in FASTBOOT MODE: press Power+Volume down button for 4-5 sec in the same time,the phone reboot, at the vibration release the power button.Now plug in the phone to the PC.
Having the bootloader locked does not prevent seeing the device in Fastboot mode.(***Not useful at the moment)
To root you must first unlock the bootloader.(***your bootloader is locked)(FAILED (remote: 'Flashing is not allowed in Lock State')
Unlock the bootloader
You must have a Xiaomi account and a valid sim.

Why look for tutorials on You tube'Sometimes good, sometimes fake) while on XDA(Always good )in the How to section of your device these tutorials exist and specify that the bootloader must be unlocked.
