Ok, I wanted to do a backup in TWRP and suddenly always received error 255. After some.searching I found a solution, but I need to look something up via ADB.
My 5T won't be recognized via ADB. My PC recognizes the phone without problem, USB debugging is on, file transfer is activated and I tried so many drivers (Google, Samsung, OnePlus of course and HTC). No change: when I get into CMD and say "ADB Devices" no devices are shown. Weirdly enough: the phone is recognized in fastboot mode.
Who can help me?
Big thanks in advance!

Thank you very much for your advice. Worked perfectly :good:
But the ADB problem still persists. There is no connection possible via ADB although the PC shows no problem whatsoever to let me send and receive files from the memory etc.
Do u have the universal adb files installed on PC also did u allow the RSA key when it prompted u

1.) Yes concerning the installation
2.) No because the OnePlus 5T doesn't prompt the RSA key. I did have ADB communication before without allowance of the RSA. I believe this RSA issue is a OnePlus specialty. I had the same issue with 5he OnePlus 5.

Hello Dito13,
I'm having the same issue you had. How did you finally fix it?

Galaxy Nexus GSM........
I cannot connect via ADB to my phone. ADB shells but 'adb devices' none is found. Drivers are installed correctly per device manager. Debugging is on.
The only thing I've found in the forums is that I can't select 'none' as my USB connection. The two check boxes won't un-check only behave like radio buttons.
I have always had to use "fastboot devices". Not sure if that is what u are looking for.

Uninstall all drivers and install those from the naked driver thread over in development.
'fastboot devices' is used only when on bootloader.

No luck. Always get 'no drivers for you phone found'. I guess I should have mentioned that I'm on W7/64 I did notice that mentioned a lot in the threads........ Any need to select the type of USB connection (none is not an option) ?
TIA, Jeff
getting there......
OK I am getting further. When I enter adb devices I can see my phone until I type 'adb reboot bootloader'. As soon as I enter that command the phone does reboot into the bootloader but the USB connection drops as well.

That is because you just installed the "adb" driver for your device. You still need to install the "fastboot" driver. It is the same driver, it just needs to be installed twice - once when your device is booted normally, and once when it is booted in fastboot mode. I personally would use the Universal Naked Drivers by 1wayjonny that bk201doesntexist mentioned, not the PDA drivers or Samsumg drivers or any other ones. 1wayjonny's drivers do not install any other software on your PC - they are just the drivers, unlike the PDA drivers.
Thanks all getting there. Thanks efrant that got me to the next problem .
I unlocked the bootloader and pushed su.zip no problem. Now I have flashed su.zip successfully but I don't have root. I have flashed many times with no luck.

Use the version of su.zip from this post. I just made it yesterday with the latest binary and app, so that one will work.
Thanks efrant that worked. I have root and installed busybox.
There was a really good terminal app that showed up when you flashed Cyanogen but I can't find it in the store. Does anyone know the name? The main thing that I need out of this whole endeavor is ssh and the terminal that came on CM8 and/or 9 was perfect.

Make sure that you have your drivers properly installed. View this guide to fix that : http://goo.gl/OS3Vi
If you still encounter the problem then you can use ADBwireless : http://goo.gl/2Ehso

Fastboot/adb

My PC's OS is windows 7 home premium service pack 1. the fastboot was unlocked through the firewater method. if you mean the android-sdk tools i got them here
developer.android.com/sdk/index.html?utm_source=weibolife
the fastboot still seems to work as i tried re-flashing TWRP. it was successful. but it still just seems to stay stuck at "Starting ADB sideload feature..."

Ok do this move everything from the folder platform-tools should be fastboot.exe and adb.exe and a few other files to the root of your c drive....
than open your CMD window as admin... make sure you open as admin... than type
Code:
cd /
to move to the root of you c dirve and then type
Code:
adb
let me know the out come of that....

I recently updated to Android 5.0.1 on my M8 GPe and it seems to work just fine. Today I wanted to flash a custom recovery but I couldn't get any connection between the phone and the computer. When I enter fastboot I don't get "fastboot usb" as I usually do.
Do I need new drivers or something? I have both Windows 7 and OS X 10.10 so a solution for either is ok.

I was also unable to get fastboot working.
For custom recovery I used adb shell and used the dd cmd, worked fine

I don't think I get any connection with adb either? But I'll try that. What command should I use to flash the recovery image in adb?
Edit: adb devices shows an empty list.

Connect via USB
To see if you have a connection type
Adb devices
U should see a device
Then follow these directions
http://www.teamw.in/project/twrp2/225
You should copy and paste the dd cmd directly into terminal, if you typo that one u may brick ur device

I'd say its the drivers. Try to reinstall
You can try adb over WiFi without the drivers, download an adb wireless app from the market, enable it, get the IP address of your phone in the app, then connect through adb
Adb connect <IP[emoji14]ORT HERE>
then try adb devices
Hi,
Not sure if this is the right place (but only place I can post) I've been trying to root my phone in order to install TWRP on my Pixel XL, in order to do so I need to unlock my bootloader.
Now this won't work as in ADB it shows my device as unauthorised, and I've tried everything! Revoking permissions USB debugging, rebooting, the other solution involces deleteing the adb key in .android, but my only .android folder is under c:\\users\MyName\.android and has no adbkey here, only 3 folders -> avd, cache and studio, all of these being empty!
I'm at a real loss to authorise my device so I can continue to root my device.
Any help would be appreciated.
Kind regards

Have tried to delete the whole .android folder ? and do you have the latest adb / fastboot files. but to unlock your bootloader you actualy dont need adb just fastboot ?
After revoking permissions did you kill and restart the adb server:
adb kill-server
adb start-server

https://plus.google.com/+YamaniMondt/posts/AjgC41SYT9h
When I run the "adb shell" commad I get the following:
C:\adb>adb shell
adb server is out of date. killing...
* daemon started successfully *
error: device unauthorized.
This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
Not sure if this helps at all

There's a possible fix until the moment you flash persist or restore EFS from another phone to yours.
ONCE AGAIN, DON'T TRY TO FLASH PERSIST OR RESTORE EFS FROM ANOTHER PHONE!!!
Just root your phone using Magisk and execute these commands using adb on your PC/laptop:
Things to note before you start executing commands below:
1. Make sure that USB debugging in your phone is turned on.
2. If everything is set properly and "adb devices" has been executed, u should see popup window about ADB allow on your phone BUT ONLY IN CASE YOU ARE USING ADB ON PC WHICH WASN'T USED FOR ADB YET. Make sure "Always allow from this PC" is checked and click "OK". Re-run command one more time. You should be able to see your device in cmd window now.
3. After "su" command, you have to grant root access to adb shell within 10 seconds.
4. "adb reboot" command will immediately reboot your phone, don't panic.
5. You are doing this at your own risk.
Code:
adb devices
adb shell
su
chown -R rfs:rfs /persist/rfs
chown -R rfs:rfs_shared /persist/hlos_rfs
adb reboot
Commands have been used from this thread: https://forum.xda-developers.com/g5-plus/how-to/fix-persist-resolve-imei0-explanation-t3825147
Good morning!
Look I was able to recover the signal (h +) with that command but not imei. Will not you know other commands that will make him recover or some method? regards
