Hello,
I want to flash TWRP 3.0 to my Galaxy s2 so i can maybe install Lineage rom. I have ADB command enabled and using "adb devices" it does recognize my phone and under device manager you can see it recognize the phone as android phone. But when entering into fastboot mode and entering "fastboot devices" it returns nothing. for some reason it doesn't recognize the phone as it should be. In device manager it does recognize it as "samsung mobile usb cdc composite device".
I have windows 10 and i tried even on mac os but no success.

Why don't you use Odin instead.
And also be aware that twrp won't work unless you have an isorec kernel, there are many guides you can use, for example the one in my description.
Thank you for your quick reply. I have found this guide which i did almost all the steps and just waiting to see that the rom is loaded.

Hello everyone..
I got an LG device that is stuck in CWM recovery, and I want to upload a file to the device using ADB. and I have two questions.
1. I'm running Windows 8.1 64bit, and tried several ADB drivers but the one that's detected was a Samsung driver, now the phone reads "Samsung android ADB interface" in the device manager. Should the device work properly?
2. When I typed the command "adb devices" the replay is normal but it says "unauthorized" instead of "device" or "recovery". Any idea what causes this or how to fix it?
Thanks in advance.
I'm trying to flash TWRP, i've got ADB and i've got the Universal ADB Drivers. The device is properly detected when in EUI and my Device ID is displayed correctly when I type 'adb devices', however when I reboot into fastboot and type 'fastboot devices', nothing is listed and cannot continue.
Which drivers do I use? What is it that I need to continue?
Thanks!
Edit: Nevermind, connected it into my linux machine and got it to work easier (lol winBLOWS amirite) and finally got it to recognize the device in fastboot mode. I kept rebooting and failing to get into TWRP. I found somewhere else that before doing 'fastboot reboot' that you should hold VOL UP so you can immediately boot into twrp and make it permanent, which ended up working for me. Freedom!

I believe you need to configure in the developers options that you don't want to have the recovery overwritten on reboot. What also seems to work is to boot into the TWRP from the command line via 'fastboot boot <recovery-file-name>'
I have the exact same problem. I have installed all drivers and adb, but as soon as i am into fastboot and my device doesnt show up in the command line. If i want to install the recovery the command line just says <waiting for device> and nothing happend.
I already enabled the "Enable AT Port" Settings (http://forum.le.com/in/index.php?threads/le-max-2-x820-qpst-not-working.14820/) but i think this is not permanent turned on on my phone, because i have to repeat this step after every reboot.
Anybody got some tips?
Edit: Also booting directly into TWRP doesnt work, 'fastboot boot <recovery-file-name>' just ends up in <waiting for device>..
If you're using Win 8 or Win 10 you should turn off the driver singing verification before installing usb drivers for device.
In your case one of the drivers was blocked from installing and the systom does not see the device after it switches in fastboot/recovery mode.
I am not allowed to post urls, so google this: How to Disable Driver Signature Verification on 64-Bit Windows 8.1 or 10 (So That You Can Install Unsigned Drivers)

Thanks for this Hint! Didnt know this
Nevertheless, no improvement so far. I Unistalled every driver and installed them again, but the PC doesnt recognize the phone when its in fastboot mode

There is a chance, that your computer has installed the WRONG driver for the fastboot mode, so find any related to the phone entries in Device Manager when the phone is connected in fastboot mode, and if it is not "Android Phone/Android ADB Interface" -> remove them with remove driver checkbox checked. Optionally, if nothing changes -> try to manually pick the device driver to Android ADB Interface

I tried it now with the fifth computer and after a few strange error messages, it "succesfully" installed TWRP.
BUT: There is no TWRP installed on my phone. I followed every tip which i found how to exit the fastboot mode (pressing Vol+ & Power / Removing USB Cable / Tried TeamSpains Automatic Installer).
What is wrong with this phone ? - I think i will oben a new thread, thanks for your help!

Kampfgans: Klingt irgendwo zwischen lustig und richtig bedrohlich...
Lots of ROMs (including most CM variants) like to "automatically 'recover'" recoveries, that is they overwrite the recovery partition with a copy of the "original" every time you reboot.
I seem to remember that my first attempt to overwrite the stock recovery using "fastboot flash recovery <twrp-image-name>" also didn't succeed in making TWRP "stick".
Within the CM13 which I installed next (over the stock v15) there is a developer option to control that, but in this case I simply used a trick, which seems to bypass the recovery overwrite: I told the phone to boot the TWRP recovery over USB after flashing.
It went like this:
fastboot flash recovery <name-and-path-of-TWRP-recovery> //puts the TWRP image on the recovery partition
fastboot boot <name-and-path-of-TWRP-recovery> //bypasses the recovery overwrite logic of either the bootloader or whereever it hides
That booted TWRP over USB and allowed me to install CM13.
There I disabled recovery overwrite in the deveoper's options and I've never had issues with TWRP disappearing since.
Actually you should in theory be able to leave the stock recovery in place and still use TWRP by booting it over USB on the fastboot command line.
I install drivers and USB but when trying to go to fast boot I receive "waiting for device"
Hello everyone, I'm using Redmi Note 3 and I have tried rooting it several times.
I have unlocked the bootloader. I have also installed the adb drivers.
When I connect phone in fastboot mode and write 'fastboot devices' in cmd it doesn't return anything. But when I connect when its on, adb devices returns the device code.
Please help.
Same, happens to mine too. Used to work with a previous install of windows, but now, nope.
Had this issue too.
Try going to Device Manager and check to see if Kedacom USB Device shows up. Under which, Android Bootloader Interface should be present. Install minimalist ADB and fastboot and right click Android Bootloader Interface. Click Update Driver Software, browse computer, and then click the option to list driver files already present on your drive. It should pull up a fastboot driver that's an older version than the one you currently have. Install that and fastboot will work again.
Doesn't work
Can you please link the files for download when we're updating the driver software.
I'm running into issues with my Compact X. Current situation:
- Omni 8.1 rom installed, but doesn't boot. Stuck on Sony logo.
- TRWP 3.3
- Rooted
- When in fastboot mode (vol up + connect usb cable) the device manager shows: Android Device > Sony Fastboot Interface.
- Windows 10 running in "Test mode"
- adb & fastboot v1.4.3
ADB does not recognize my device when the device is in fastboot mode. When it's in recovery mode the command 'adb devices' shows me the device listed. I can then reboot in fastboot mode, but then the device isn't listed anymore. I'm not sure what happened because a couple of hours ago I installed TWRP using fastboot.
I'm trying to get this thing up and running again, but not being able to flash anything via fastboot complicates things. Any idea's what could be the culprit?
Download official Android drivers by Google and force Install them (search: Force Install Windows drivers" anywhere preferably YouTube

Thank you for your reply. As far as I know the official drivers were already installed. Because at first my device did show up listed when using the command 'adb devices' and I successfully flashed TWRP recovery. But to be sure I repeated the process:
- Connected my phone in fastboot mode (vol up + connect usb cable). The blue led lights up.
- Go to the device manager, right click on 'Android ADB interface' device and manually install the driver via 'Have disk'.
- The driver installs with no errors.
But still my phone is not listed and I cannot flash anything.
When the phone is in recovery mode it is listed using the 'adb devices' command. But when I'm trying to flash something I get the message <waiting for device> .
Ok, I restored my computer to a point before I started messing with my phone. After installing the official drivers my phone is still not listed (adb devices), but this time flashing did work. I managed to flash the AOSP 8.1 image. My phone is up and running again!
Once I reboot to bootloader and connect to PC, the command "fastboot devices" does not recognize the device, so when I try to unlock it. it says "waiting for device". I've enabled both OEM unlocking and USB debugging.
The phone shows "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. "
EDIT: Solved it by using the correct platform-tools
I have the same problem. I actually thought that I installed the right sdk platform tools. Can you upload the platform tools that work for you?
Thank you

I used the ones from here - https://www.getdroidtips.com/download-adb/#How-to-Install-Android-SDK-and-Platform-Tools
Solved.
I downloaded the platform tools 30.0.5 and reinstall it. Then i reinstall the adb bootloader driver right at the moment when the Nord2 is in the fastboot mode.
cheers
I have no developer options for reboot, bootloader, recovery.
platform tools 30.0.5, where?
Try after reboot into bootloader "fastboot devices". Is the Nord 2 recognized?
For me the correct command was "fastboot flashing unlock".

I'm having the same issue. I can't get my Nord 2 show up with "fastboot devices". Sent my phone into the bootloader with "adb reboot bootloader" no problem.
I have used the 30.0.5 platform tools as well as the 31.0.3. Installed Oneplus USB drivers and also tried the universal r13 android drivers (Reinstalled the bootloader drivers while in bootloader mode). Also tried Snoop05s 1.43 adb installer. All to no avail. Just can't get my device to show up in the bootloader.
In Phone settings bootloader is open and USB debugging is on.
Edit: I made it work. Used regular CMD and not powershell and it showed up.
