Dear all,
Please Help me. My One plus one is on CM12 official rom (rooted). Problem is when I connect my phone to computer and use ADB it is detected (adb devices: number & devices detected) but when in fastboot (fastboot devices : nothing is detected) I check in my device manager (yellow triangle on android ) My problem is why CAN it be detected when my phone is on but NOT during fastboot.
Necessary checks done : USB debugging, Universal driver, SDK installed, USB driver reinstalled again, tried changing usb ports on computer, tried on 2 laptops)
I am helpless, tried checking on forums can not find the answer.

Tried adb reboot bootloader then phone boots into fastboot mode but from here..
is total no connection. Tried checking fastboot devices (nothing), fastboot reboot (waiting)
then i tried as u said unplug & plug in (not recognize) from here adb cannot be written anymore. (no more commands can be typed). Tried others like down loading Pdanet ,force install driver..Nothing works. Thinking ,did I corupt the bootloader while I was rooting it last time.?
I think if something was wrong with bootloader you could not either boot .
Do you use antivirus to pc?
Try without antivirus
What happening the false is from computer
Mine is reverse issue. When in fastboot mode, pc recognizes OPO, but when OPO is normally connected to pc, adb is not working. Its charging and can transfer data through USB, but OPO is not recognized through adb commands. Device Manager too recognizes my OPO only when it is in fastboot mode and not when normally connected via USB for data transfer.
I have a software, through which I can REVERSE TETHER my PC's internet to my mobile via USB. Because my OPO is not recognized via USB in normal mode, I can't do that. Any idea, what's wrong with my OPO.
(I have installed Android SDK and google usb drivers, for my OPO to work in fastboot. I have rooted. My pc runs on win7)

HI,
i was replacing the screen and suddenly my phone went in coma the sreen has been changed but no recovery or fast boot is accessible and even my pc is detecting it as mtp device and in adb cmd it says unauthorized or offline i need your help or my brother will kill me:crying::crying::crying: please help asap
i tried the hardbrick method but the driver installation dint succeed and the phone is still recognized as android device or mtp device.
MTP device and adb recognizes it means the phone is running fine! Check the display it sounds like it's issue.. And also when connected to PC try holding down power button and see if mtp device indication goes away (hold it for like 10 secs)

Before installing android 10 my pc was recognition successfully fastboot/ edl mode.but now at android 10 nothing helps . What can i do?
Jtag,changing motherboard ?
Where i can find motherboard?
Or maybe its because of installed a lot of fastboot/adl drivers maybe?
When try fastboot devices shows nothing
For anyone who drivers works
can you write your ADB/fastboot driver version?
I have a Huawei p20 with a broken screen and the touch does not work, after research I discovered that the only solution to get all my data back is via adb (and perhaps also fastboot), only that when I connect it to the pc it gives access, it recognizes the but the device is unauthorized instead in recovery mode it does not recognize it, but if I try it in fastboot mode it recognizes it as fastboot, how can I use adb?

unfortunately this post doesn't help me, as it tells them how to activate usb debugging, my problem is that when i'm in recovery it doesn't show me that my device when i type adb devices command
Looks USB is OK, because Fastboot works. But I guess that ADB isn't properly installed, especially ADB Verification failed. So you can't successfully run ADB, neither when phone is in normal mode nor when in recovery mode
