Can't get USB Debugging to work - Razer Phone 2 Questions & Answers

Hey guys,
I'm trying to connect to adb but my phone is not ever popping up the window to authorize the computer for USB Debugging. I installed the drivers from here https://forum.xda-developers.com/showthread.php?t=2588979 and it didn't help
My phone says it's connected in USB Debugging mode, but I can't ever connect through ADB

Try installing the drivers manually. Have the phone connected in debug mode. Download here and unzip: https://dl-ssl.google.com/android/repository/latest_usb_driver_windows.zip
Then follow this tutorial. Ignore the first 4 steps since you already downloaded the drivers. In step 12 select the folder you unzipped. https://visualgdb.com/KB/usbdebug-manual/

I don't remember the exact steps, but I had to delete a file that was under an .android folder in my documents (not where ADB was installed)

I presume that you're unlocking your bootloader...
When adb is "waiting for device", just double click on the installer. Do it untill the device be recognized.
I had to alternate, installing LG Drivers and "CT_HsPhone_General_Drivers" several times, only in the
3rd time (not sure exactly...) the device was recognized

I intend to make the bootloader unlock process for official LG's "laufersteppenwolf" post, and you need the lg drives and drives fastboot. Thanks for the help:good:

ADB problem and no OS on device

Last night, on TWRP I formated data on the SD card, which is why I have no OS. Now looking for how to fix this on xda/google, I get into the bootloader, have fastboot usb and try to adb shell but I keep getting the "error no device found". I already installed latest drivers from HTC on to my laptop and still nothing. Any other idea?
windows 8?
First off, make sure you have HTC Sync Manager installed because that will give you the proper drivers in order to be able to use ADB commands.
Afterwards, make sure you install Java JDK and Android SDK.
Just follow this tutorial here: http://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android-debug-bridge-utility/
Follow it word for word and make sure you install JDK X86 even if you have a X64 computer. And then download SDK Manager, put it in C:/ drive, open SDK Manager, and download the necessary tools (also all in the tutorial).
I was in the same position as you just before yesterday and I followed this tutorial with success.

I'll look into both things, thanks.
EDIT: even on my mac adb does not see any devices, before when I entered ./adb devices it would show "list of devices:" and it would be blank.
Good luck, man. It's fairly easy once you read the tutorial carefully and follow all the steps to the word. After it's all done and the command prompt says Sideload 100%, boot into TWRP, tap INSTALL and then scroll down to sideload.zip and that's your ROM. Also after copying the desired ROM to platform-tools in the SDK folder, rename it to rom.zip, it seems to work 100% that way while it struggles a bit with long names.

Still getting the error: device not found.
I even ran the all in one tool kit and attempted the "ADB sideload a ROM" follow the steps but get an error on CMD "C:\users\(username) is not recognized as an internal or external command, operable program or batch file"
I really do not understand why adb is not working, I did s-off and supercid myself maybe less than a week ago.
Are you sure you followed all the steps in the tutorial including installing JDK, using SDK Manager to download some tools and such? And are you sure you have the proper drivers installed (e.g HTC Sync Manager)? I used to get that error before I installed it. Go to Device Manager while in ADB mode in TWRP and see if the device is recognized or if there's a yellow sign beside it indicating that there are no drivers for it.

It came up under Android USB Devices as My HTC. When I was following the steps on the link you provided, when I tried to update the drivers with the google usb driver wouldnt work, it would say "windows had determined the driver software for your device is up to date". When I go into My HTC properties says the driver version is 2.0.7.18.
The Google USB drivers did not work for me either, only the ones provided by HTC Sync Manager did. I have not experienced that problem, mate, so I do not know what to do at this point, I am very sorry. If you are not able to fix this, I suggest getting an OTG cable and directly loading the ROM from the PC to your SD card. I ordered one a couple of days ago and it is coming tomorrow, it's very helpful

Crap, I appreciate your help though.
EDIT: nevermind googled it, gonna pick one up. Phoneless till wednesday
I am sorry to hear that, but I suppose that's the only thing you can do at the moment. Even if somehow get ADB working, do not cancel your order because OTG cables aren't only used for mounting the device, but also for things like connecting gamepads and controllers to play games on your device.
USB 3
If you have USB3 port adb.exe wan't recognize your device.
I triend first on USB3 and after on other older computer on USB2 all was fine

You can't acces to "adb shell" without OS, there is special mode in adb named "adb sideload" , not shell !
1) Check version adb by "adb version" you need version 1.0.29 or higher
2) Check TWRP version (2.3 or higher) Go to TWRP recovery -> adb sideload
3) Connect PC to phone , at PC in device manager must be MY HTC device.
4) Type jn PC adb sideload /yourpath/yourrom.zip

[Q] PLEASE HELP!! No OS after wipe

Hello!
I have an HTC one developer edition, I did an advance wipe of my phone because it wasn't charging, it said that USB Host mode was on. It only charged when the phone was off. I decided to wipe everything but the pictures (or so I thought) but once it finished the wipe the entire OS systems was erased, know the only thing I can do is enter TWRP.
Please Help I just bought the phone!

chose whatever rom you want as long its compatible with your device variant and compatible with your twrp version.
what do you mean by doesn't read the phone? its is not detected as sideload when you type ''adb devices''?

.exe file extension might be hidden depending your windows configuration. Go ahead with the guide it should work.
Open a cmd prompt from that folder. (shift + right click in a blank space) (step 4)
with you device in twrp sideload mode (step 1,2,3 completed)
type in the cmd prompt:
Code:
adb devices
make sure it output your device s/n + sideload
then
Code:
adb sideload <name_of_rom>.zip
what rom did you downloaded?

Hello, I got a problem with my phone. Is possible to turn on my phone, but screen doesn't works. Just black screen and nothing more.

if you had turned on "usb debugging" from the developer option menu or i you already have a custom recovery installed, you can use adb to pull your files
adb pull <remote> <locale>

Code:

Looking to go AOSP from Stock KK [4.4.4]

Sooooooooooo,
I have a Z1 [C6903] that I picked up yesterday. It came with 14.2.A.1.136 Jellybean 4.3.
I wanted to
Unlock bootloader
Install custom recovery
Root
Install any nice AOSP ROM [preferably LP-based]
I installed the Minimal ADB-Fastboot 1.4.
I also installed the Flashtool 0.9.18.2.
I also installed the Z1 device, Fastboot, and Flashmode drivers [version 1.6.2] from the driver folder. It first failed, and then I disabled driver verification then everything went smooth!
Device manager recognized the phone in MTP and Fastboot, and Flashmode modes. Drivers installed correctly I presume.
Then the challenges arrive:
adb devices returned it as "offline"
Android studio couldn't push a project to it because it was offline
fastboot devices identified it, but fastboot -i 0x0fce getvar version returned an error [getvar:version FAILED (command write failed (Unknown error))]
Things I've tried to do to rectify the connectivity issue:
I'm using a SurfacePro 4 so I can't switch USB ports [only have one].
I've tried different cables - they yield the same result.
I've enabled and disabled USB debugging, revoked access, unplugged and replugged, rebooted, etc. Still no change in result.
Since the device had some OTA updates pending, I ran those and now i'm on 4.4.4 with 14.4.A.0.157, with some other updates currently waiting for me to accept so they can download. I've decided to post here for help and won't run those updates unless it increases my profit
PS: Even after the updates, adb and fastboot still are unchanged in their results.
Help please
Update:
It was a freaking USB cable. I had tried two of them. None had worked.
I finally unleashed my Anker USB cable and Boom! We good to go!!!
Thanks all!:highfive::highfive::highfive::highfive:

Excellent! I did that, too. even manually closed and restarted adb.exe to no avail.
The thing is, my Z1 DOES NOT show me the authorization pop-up! Ever!
I've done this a million times on other phones, and I know the procedure. It's just that this Z1 is not showing the authorization popup
Thoughts?

this could work with you
i assume that you rooted your phone you will do that:
1. open your favorite file explorer(suggest: ES File Manger)
2.go to /data/misc/adb/
3.delete "adb_keys" file
4.enable usb debugging
5.reinstall your drivers
6.open command and kill adb server(adb kill-server)
7.connect your device and run command (adb devices)
8.look at your device you will find text box telling you a new pc check always trust bla bla and click trust or something like that

Hey there! Please check here for a firmware file that works for you.
When you've downloaded, use the Flashtool to flash it to your phone.
If you want help flashing it to your phone, check this thread out.

Hey, thanks for the advice!!
Finally got root [without use of PC] and when I open the /data/misc/adb/, the folder is EMPTY
A little confused there.
I did the same procedure for the PC [deleting from C:/Users/boydee/.android/] but it also was to no avail.

This could problem with installing drivers as PC don't detect adb in debugging mode
So disable driver verification again and install drivers from flashtool remember to check
1. Fastboot drivers
2. Flashmode drivers
3. Xperia Z1 drivers
And restart
If the problem not fixed try adb universal drivers just Google it
I was have same problem with win 8.1 but I didn't all that I just installed win 7 and do it
Remember to backup ta before unlock to backup your DRM keys
