Depends on variant/firmware you have installed. Don't think AT&T firmware will let you do that. That's probably what you have?
What are you hoping to do in ADB? You're not going to be able to unlock bootloader or anything...

I'm running windows 8.1 and I installed htc sync for drivers.
If some1 know how to fix this problem i would be appriciate it,

Are you booted into OS, or in bootloader? adb won't work in bootloader.
Do fastboot commands work? You need to be in bootloader-fastboot mode for that.

how to unlock the swift bootloader?

I want to root my swift.
I understand that first I need to unlock the bootloader.
downloaded the android studio in order to have adb and fastboot. ??
downloaded both supersu.zip & cm-13.0-20160316-SNAPSHOT
moved them both to sd card
I start the swift pressing power and volume button up i get the fastboot screen.
I connect to my mac.
nothing happens.
Ive seen an earlier post on xda explaining how to unlock the boot loader by inputing code from the computer to the swift but it looks like my mac does not recognize the phone[swift]
any ideas?
cheers

Have you done the other steps as well? Enabling ADB debugging and OEM unlock from settings?
When you are in fastboot mode, what is the output from:
fastboot devices
thanks

Thanks for trying to help.
I somehow managed to cobble enough info form the web and by some miracle managed to root my device without bricking it.
I dont think i would be able to repeat the procedure.
cheers
2 points:
1. The 'Install ADB and fastboot on Windows with Minimal ADB and Fastboot' procedure does not allow specifying where adb & fastboot are installed. They actually install to c:/adb folder.
2. 'adb devices' does not show my Wileyfox Swift phone.

Help I bricked my Oneplus 3

Hi, i played around with my new OP3, and i wanted to root it. Since i'm noob at rooting, it went wrong. (i did it with twrp)
So first it just went in to bootloop, then i was still able to get to rcovery and stuff, but i followed a guide to fix bootloop, and that ****ed it even more up. The guide i followedet told me to use "OnePlus3_Unbrick_Tool"
After using "OnePlus3_Unbrick_Tool", i now cant even go into recovery anymore, the only thing i can do is go to bootloader, but when i'm in bootloader now, it wont connect proberly, so that i can use "flash twrp", so that i can use twrp recovery.
Also when i try to boot it, it because of "OnePlus3_Unbrick_Tool" goes into something, where it says "md5 checksum failed", and then restarts and does it again and again.....
I hope it's not bricked forever, pls help ))
have you tried re-flashing the stock or twrp recovery with adb sideload command?
if not give it a shot, it might work.

And how do you say I do that? I have tried using the "tool all in one", where you han flash both stock and twrp, but it doesnt seem to do anything, when i press them (and the device is in bootloader)

Just boot into bootloader mode and through command prompt check if your phone is detected by typing fastboot devices. If its detected then you flash a new recovery again. Forget the toolkit, just look for instructions on how to install a custom recovery.

In fastboot mode, did you manage to find your device on the computer? On Linux this is "sudo fastboot devices", on Windows it should be roughly similar.

Hey!
I'm not the expert but I have played with my 1+3 enough to have some knowledge.
First of all, do not use "all in one tools", those do not put you in control.
Cool, so fastboot is detected, though you can't get into the recovery?
Step 1) make sure you have the latest version of "fastboot" and "adb" (Android Debug Bridge) and unlock the bootloader. This tread should be helpfull: http://forum.xda-developers.com/oneplus-3/how-to/oneplus-3-how-to-unlock-bootloader-t3398733
You need to do this, because otherwise we will not be able to proceed (i.e. the phone is to be 'unlocked' for what we are about to do).
Step 2) If you are ready than let's flash a new recovery (TWRP):
This is also step 2 in the thread mentioned above. Very important: "Once the flash has completed, Don't use the "Fastboot Reboot" Command Instead Unplug Your phone then Manually boot it into recovery by keeping Power + Volume Down button pressed."
So once you have flashed a new recovery using fastboot, than you should reboot your phone into the new recovery!
step 3)
Once in the new recovery (TWRP) go to advanced and to ADB sideload. Make sure your computer detects your device with the command "adb devices" and flash a new ROM. Just for simplicity use the official OOS 3.2.4.
This should do the trick. Before you go and try make sure you understand EVERYTHING I have written. Let me know if you have questions.

Thank you, but i have not enabled "allow oem unlocking" in the developer settings when the phone worked, so i get a error message "FAILED (remote: oem unloc is not allowed)
What to do to unlock it then?
Bro, download 3.2.4 oos rom zip file from official link. Its around 1.3 GB. Just connect ur OP3 to computer. It will detect as MTP device.Im my computer it was in the name of RAIN Transfer the zip file to internal storage. Wipe cache. And select install option in TWRP and select the zip file u pushed and flash it. Best of luck..

Hey i have the same problem but this fix does not work for me.
So I have the bootloader unlocked and I can enter the bootload and my computer detects my device which is nice.
when I flash twrp on my phone trough CMD it doesnt work, my PC tells me that everything is okay but my phone will not boot into twrp and instead it will give me weird errors.
---------- Post added at 03:31 PM ---------- Previous post was at 02:56 PM ----------
this fix worked for me,
On the screen when the phone failed to md5 checksum, you've got several partition failed right? in red text.
- download this : https://www.androidfilehost.com/?fid=24591000424942573
and then extract.
- download platform tools attached below. extract in the same folder with first file you've downloaded.
- Boot your phone to fastboot mode, plug your usb, make sure adb and fastboot driver are installed.
- on the folder, hold shift and right click, click open command here
- type fastboot devices
- make sure your serial number appear.
- now flash the img of the missing file according to the partition in red text on your ms5 checksum failed one by one.
- e.g. "fastboot flash boot_aging boot_aging.img.
- make sure you flash all the missing partition.
- type fastboot reboot.
this will boot you to oos 3.1.2.
unfortunately I couldn't extract the newest oos dat. data. but you could always take the OTA
goodluck mate. sorry for my english

Hmm bad try installing all op3 drivers and see whether phone is detected or not. I was in the same situation previously. Pushing zip through adp terminal is painful process. I got device offline first,after solving that i got service not recognized issue. For solving that usb debugging needs to be enabled i stuck in that step.
can you enter recovery trough fastboot mode? I.e. if you are in fastboot mode you van use the volume keys to select recovery.
100% sure you can't enter recovery?
you can try Fast and pro's option. let us know!

fastboot never start after update to android 6

Hy
I had an unlocked bootloader phone. Yesterday I flashed the new Android 6, Europe version from the Huawei blog forum, no beta, on my Huawei GX8. I used the method, dload on SD card, Phone off an the press Volume down+volume up+Power button.The flashing was normaly.
Now the phone starts normaly but I can´t start fastboot. When the phone is off and i press Vol down + Power the phone start the android system and the Huawei logo is coming not the fastboot Modus. I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!
Should be connect the charger cable to the phone.

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.
i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.
Here is screenshot from minimal adb...
Phone must be in MTP mode.
And here is phone in fastboot
Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

OP3 Broken screen - how to extract data?

Hi,
I have OP3 with broken screen but it turns on (there is a LED blinking , and on my computer I see the OP3 CD installation & the device but I cannot access the data)

Insufficient info.
Are you able to boot up? Are you able to boot to bootloader? Do you have TWRP and are you able to boot to it?
Is your bootloader unlocked? Are you rooted? Is USB debugging enabled?
Does "adb devices" / "fastboot devices" command find your phone? What ROM?

sorry ,
I think I am able to boot to the bootloader (but I cannot see it since my screen is broken)
my bootloader is unlocked , device is rooted and USB debugging is enabled
while pressing Power+Vol UP I can get into fast boot and see my device on fastboot devices
anything else I need?
To clear things up, TWRP is recovery and not bootloader. Fastboot is bootloader.
So, if you can boot into TWRP, you should be able to use adb commands. Try booting into it, then try "adb devices" and see if it's properly detected (adb reports device's serial number and status "recovery"). You can then use "adb pull" command to get your data.

Ok, an alternative then:
- download latest TWRP .img file to your PC
- open command window in folder with the file (Shift + right click > open command window here)
- boot into fastboot (Power + Vol Down) - you said you managed that before - and connect the device to PC. If it's properly detected in fastboot, you can boot custom recovery with "fastboot boot <recovery-name>.img"
Phone should now restart and boot into previously downloaded recovery. Now you can try and see if adb works.
Easier option would be simply "fastboot reboot recovery", but that command is non-standard and doesn't work on OP3 if I remember correctly. You can try though, nothing to lose.
