Lg velvet 900um1 - Android Q&A, Help & Troubleshooting

I cannot get adb to recognize my device in download mode. I have installed all the necessary drivers, got usb debugging enabled and even switched out cables. If anybody has a solution to this it would be greatly appreciated. I'm trying to falsh a boot img with magisk to root my device, but download mode is not recognized.

ADB doesn't work in Fastboot ( AKA Download and/or Bootloader ) mode: you have to use
Code:
fastboot devices
fastboot <FASTBOOT-SUBCOMMAND-HERE>

Why you enter the download mode - that is LAF mode - at all?
Normally there is no adb nor fastboot in that mode...

[Q] LG optimus c stuck in fastboot mode PLEASE HELP

i tried to flash a recovery and it didnt work and the phone is stuck in fastboot mode
use this
BUT, before you even do a thing, know that you have to use the files that are meant for your phone (you need the recovery and usb drivers meant for your phone; i believe you can use the other files)

My phone can't get to emergency mode and stuck in fastboot mode i have rooted my phone and backed up rom rebooted phone and went straight to fastboot mode what do i do
lg optimus c
Yes the tut didn't work for my phone. for some reason its not being recognized by the fastboot shell nor adb shell. I'd assume its completely bricked ? thanks for all the help.
My phone was not recognized by neither fastboot nor adb while in fastboot mode. "adb devices" and "fastboot devices" generated no result. Nevertheless, the following command worked flawlessly
fastboot flash recovery recovery.img
So, it seems that it's not necessary for the phone to show up in adb or fastboot.

Fastboot mode on Acer A3-A30

Hi!
I recently got my new Acer Tablet A3-A30. After unlocking developer options and activating debugging I was able to use adb. So I rebooted into bootloader to see if fastboot works - it did not! The output of fastboot devices was empty (this and the following commands were typed as root).
So I killed adb with adb kill-server, disconnected it from my computer and turned it off. After a few moments I turned it on by pressing power while holding Vol[-]-Key. Again the tablet booted into fastboot mode. Now I connected it with my computer and hoped fastboot will recognize the device now. Again, the output was empty.
I noticed, that after connecting the tablet, the text fastboot mode on the display didn't change - all other devices I put into fastboot mode showed fastboot usb mode or similar after I connected them with my computer.
I tried different USB ports - nothing changed.
I'm just wondering, since I'm not familiar with acer devices: Is there a hidden key sequence to get into fastboot usb mode?
Thanks,
Tintom1

I have an a1-830 and it can be a real pain in the ass to get anything working on them. Try this, since you got adb working, adb reboot bootloader, then wait till it says fastboot cmd waiting or something. If that din't work, reply!

But this is what I already got. It says fastboot mode (now with the waiting message), but not fastboot usb, so fastboot still doesn't see the device

If you are using Linux, try running fastboot with the sudo command. Also, the drivers might not be properly installed, check out this to download them.

Hi:
My unlocked bootloader SS2 phone got stucked in Download Mode after successfully installed/flashed AICP ROM
It booted once and when i rebooted to enter recovery got stucked. Tried pushing buttons combos but still stucked in Dmode.

Regards.
EDIT: reinstalled treble v3.1 via OST and it fixed the download mode issue.
thanks!

Maybe use other fastboot.
Sometimes you must enter:
Code:
fastboot --set-active=_a reboot
("_a" instead of "a")
BTW. My Aquos sometimes stuck in download mode after installing AICP.
I fixed this by entering:
Code:
adb shell
bootctl mark-boot-successful
Hello, i have the same exact problem. I tried to use adb program to fix this problem, but my laptop couldn't recognize my device. Any other solutions would be helpful. Thanks for your attention! (I'm a beginner in technology, so please forgive me)

Fastboot help

My PC doesn't detect my phone when I use Fastboot Devices when my phone is on Fastboot mode. I get a blank space in return. Can anyone help me with this? ADB works fine, it's only Fastboot. Is there a Fastboot driver that I might be missing?
Thank you.
Edit: I'm trying to unlock the bootloader of my phone.
Me too !
Drivers are here: https://developer.android.com/studio/run/win-usb
These are the ones I use for ADB/Fastboot.
May I ask if anybody solved this already?
Having the same issue, tried various drivers, but fastboot won't find my phone
Help is highly apperciated!
Clock
If you using windows 10 have you disable the drivers signature verification.. And search on here (XDA) for Min ADB & Fastboot tools, easier than using SDK tools unless you modding apks ect..
Okay, I got this working.
When in fastboot mode, you have to go to the device manager, update driver, and manually choose the google fastboot driver. Then the ! is gone and it works.

Question Fastboot?

Hello.
Today I updated from the Nord 5G to the Nord 2 5G.
DN2103_11_A.14
I have enabled developer mode, oem unlock and adb debug.
I can't access fastboot properly. And recovery is different from the previous Nord. There is no option to reboot to fastboot.
I use adb reboot-fastboot and I enter a sort of fastboot. It says:
fastboot_unlock_verify ok
The device is in fastboot mode which is only for debug Android devices. if you want to exit fastboot mode, please long press volume up nad power buttons simultaneously.
Phone is recognized in windows when in adb-mode (normal booted), but does not recognize it when in this new fastboot mode. Just an Android with an exclamation mark on.
Halp?

Don't own this device but try: "adb reboot bootloader" instead and test fastboot commands from there (don't navigate to Fasboot from bootloader).

This is normal behaviour with the OPN2 afaik. Your PC can access the USERDATA folder whilst in ADB mode (aka booted normally) and whilst in the recovery bios. Your pc CANNOT access the USERDATA folder when your phone is in fastboot, or at least I've never been able to on my Nord 2.
Your op didn't include what exactly you need help with. Everything you described is exactly intended behaviour. From my understanding your seem to have booted into fastboot mode, then noticed your PC can't access userdata. That's normal, you can still use fastboot commands and your PC is still connected to the phone. Your "My Computer" folder on PC not showing the phone shouldn't be any cause for alarm.
Now I'm starting to guess, because you might have failed to mention; Are you unable to send fastboot commands to your phone when its in fastboot mode?
Are you trying to flash a file?
What's the issue?

I am unable to send fastboot commands. Is not recognized by "fastboot devices". And this fastboot mode looks nothing like my previous phones. 2, X, 5T and Nord 5G. <waiting for device>
I want to do my "usual routine" with my new phones. Unlock, flash twrp or other recovery, and flash magisk for root.
After a "full wipe" of ADB and fastboot drivers, I reinstalled and got it working!
nothing. only recovery mode
vol down+ power =recovery mode
vol up + power = normal boot
I finaly boot into fastboot mode with adb command only (adb reboot bootloader)
With buttons wont work.
But i can't enable Volte/Vowifi (thats why i wanted to boot there).
Can you send adb commands when in recovery mode ?
I'm trying to enable VoLTE too, but adb only detect phone when powered normaly, not when in recovery mode.
i don't know about adb but in fastboot you can.
I can't enable volte/vowifi in fastboot with this commands.

Fastboot commands start with fastboot, those are adb commands.

Could you go into more detail on what you did in the entire process exactly? Did you use the drivers and adb install from the 15 sec installer? Did you simply uninstall them in the Windows Device Manager and click on "update drivers" to find the local drivers from the 15 sec installer? Which ones did you choose? Sorry, these might be dumb questions, but I'm admittedly very stupid when it comes to Windows and drivers in particular.
I did the exact thing I described above but I'm still just getting that message. Additionally, "fastboot devices" won't list anything and "fastboot oem unlock" will wait for the device for eternaty. "adb devices" on the other hand will list my device while not in Fastboot.
