Is adb bugs on model SMJ200G (j2) common? - Samsung Galaxy J2 Questions & Answers

I investigated the ADB program. At How to Install ADB on Windows, macOS, and Linux, I am stuck at step 7 of the instructions for windows. I do not receive any kind of pop up in my SMJ200G phone (j2).
This step:
7. On your phone’s screen, you should see a prompt to allow or deny USB Debugging access. Naturally, you will want to grant USB Debugging access when prompted (and tap the always allow check box if you never want to see that prompt again).

Perhaps my PC's connection to the phone is buggy, not the cable, but the software? by software I mean Windows/PC not my phone.
btw does file AdbWinUsbApi.dll need to be installed?
Are the following applicable for a official device that have never been rooted:

Unable to detect the phone -win nor Lin
Hello guys
Something really extrange is happening.
My j2 prime -532G- can't be detected by Windows nor Linux.
The usb is working because it charges the phone, but I can't access the phone at all. I checked all the drivers in Win -google/adb and samsung- and in Linux libmtp/heimdall/etc.
I have tryed different usb -not the original one since i lost it-
Even when i start the download mode, nothing happens.
it there a way to root the phone without a PC? i have tryed also kingroot apk but it is useless.
Thanks

[Q] adb on Mac OSX

Anyone got adb on latest Mac OSX working? I can connect in MTP mode but adb devices never shows my phone. Tried the Unified Driver v4.5 and v4.7 to no avail.

http://www.mylgphones.com/tag/usb-drivers try these drivers
That's the ones that didn't work.
Same problem here... Any luck?
Change the USB mode to PTP and you should get the RSA prompt.

Yes I have install Google universal usb drivers worked for me search on Google for them
PTP worked for me, no LG driver installed.
Just got my G3 on Verizon, cannot see the device over ADB either on Mac OSX
I tried MTP, PTP, and Charge only both with and without LG drivers installed. Since it's OSX, there are no Google Universal USB drivers.
Android File Transfer opens up fine, but ADB doesn't show the device. Quite fishy indeed.

May I ask how you managed to connect your phone to your mac via MTP? I am unable to get any kind of connection to my mac.
On windows it works finde, I can open the internal and external sd card and copy files from and to the device, I would be more than happy to achive the same on my mac.

Hi there, you will first need to enable USB Debugging. Head over to Settings > General > About Phone > Software Information. Tap Build Number 5 times, and you'll unlock the Developer options.
Go to Settings > Developer options, and check USB Debugging. From there, ADB should work. Good luck!
OK, so I installed the new drivers, rebooted, and got ADB to recognize my LG, and was able to debug successfully. Now Android File Transfer doesn't see it, nor does Finder show the device. What am I missing?
It's broken, I saw a tweet from jcase regarding the issue. I have the same problem. I just adb push/pull when necessary for now.

Mine works fine on my Mac

I know this is a seriously old thread, but for future reference - if your device is NEVER recognised by adb from the start, no matter how much you add the vendor etc, open up Terminal.app and type this in:
cd ~/.android/
rm adbkey adbkey.pub
This will navigate to android's folder and remove the RSA keys your computer uses to identify with the phone. If the address of the folder is wrong you can alter the first line to whatever is appropriate.

Seriously old, and seriously unresolved (for me and a few people on reddit, at least). Still have not succeeded at getting ADB to detect G3 on USB, tried running the -usb flag on the cli and everything. Is there a working process yet? Verizon seems to be the outlier here as well...
Just worked for me on OSX Yosemite with a D855 on V10l:
- Update ADB (android platform tools)
- Install LG Driver (link is in this thread)
- Reboot
- run "rm ~/.android/adbkey" and "rm ~/.android/adbkey.pub"
- run "adb devices" (you should now see your G3)
- run "adb kill-server" (just to make sure there is no interference)
- quit all applications on your phone and go to home screen
- run "purpledrake_osx.command" which should now work
Inbetween (guess it was directly after running "purpledrake_osx.command") you should get a permission request on your phone which you should allow
Thanks

Also on El Capitan:
After enabling developer settings + USB debugging on phone (see earlier in thread),
Removing the adbkey + pub from the users .android folder (see earlier in thread),

It finally works

[Q] Driver install problem w/ Mac

I'm having some trouble and I think it might be related to drivers. I'm on Mac OSX 10.8.5 so I downloaded the LGUnitedMobile_Mac_Driver_Ver_4.22 from here:
http://www.andromods.com/download-files/latest-lg-g4-drivers-usb-adb-win-mac.html
I installed, restarted computer. When I plug in the G4 via USB I don't get the popup requesting ADB access. (I've got USB debugging on in Developer Options and it shows as on in Developer Options as well as a notification in the pulldown menu). If I tap on the notification from the pulldown for MTP options I'm asked if I want to install the drivers. So, I do that too and wait for it to complete. Still no ADB popup. If I open the Debloater tool, no welcome popup and the "device connected" light is red.
I tried toggling between MTP and PTP and still nothing. Tried unauthorizing my computer in Developer Options, unplugging, and waiting. Tried restarting phone.
Further, if I open Android File Transfer I get a message "No Android device found" whereas before trying to install the driver it found the G4 just fine. Ran the uninstall script from the LG driver software and Android File Transfer then CAN see the phone.
Any ideas? Any help would be appreciated - I'm trying to run the Debloater tool (which can't see the G4 either no matter what I try).

You won't get the adb popup until you run an adb command in terminal. for example adb devices command is what triggered my popup.

If I remember correctly you need to download the android sdk and install the sdk and platform tools. When you do this make sure you make a folder on your desktop and name it whatever you want, and when you install the sdk make sure the install path goes to the folder you made. Then open a terminal window and navigate to the folder you installed the sdk to.
Then run the adb command, but it will be slightly different:
./adb devices

I'm not talking about fingerprint protection, when you switch to other modes aside form Charing when you have USB debugging turned on, if will prompt you to accept the computers fingerprint, meaning make alterations to your device.
You need to allow that, and if you're not getting that prompt, update your sdk tool, drivers, u install the drivers, reinstall them, try a different cable/USB port/ computer. Pretty much do all the basic trouble shooting.
My device was very picky about what port I could use

I hope someone still sees this post. I have a friends Google Pixel XL that I was able to revive from a bootloop by sideloading the latest OTA. Upon starting up, my friend forgot his screenlock passcode. I've been trying everything to get the device recognized in bootloader mode on my pc. It keeps showing up blank. I am trying to use ADB to bypass the unlock code. If anyone has an idea how I can get into this phone BEFORE I reset it, that would be very appreciated! It is not rooted and no unlocked bootloader.

You have to enable USB Debugging in settings in order to delete the unlock code. Unfortunately, you can't because he forgot it. You can try booting TWRP on the device using fastboot and see if you can delete the unlock code's key file using TWRP's file manager, but the reality here is that you likely will have to reset. Hope your friend didn't use a throwaway email address when setting up the device.

Pixel 2 XL isn't detected on my PC [help]

After upgrading to Android Q suddenly my pc can't recognize my pixel as a android device also i can't connect any wired things such as dongle jack or USB Transfer (USB charging options disappeared).
Planning to downgrade to Pie but the problem is my device can't be detected on my pc. Any solutions? Thanks
If you're using a Microsoft Windows machine, I would suggest uninstalling any "Android" drivers from the Device Manager. Then restart the PC, then turn off "USB debugging" and back on for the Pixel, and even "Revoke authorizations" in hopes that it will re-alert & request another authorization and, therefore, verify it being connected and detected on the PC....
After all that -- or if you can only enter in Bootloader Mode -- type the command "fastboot devices" and say here what it outputs. If anything, while in Bootloader Mode, do what I previously said, but look for anything "Android" and "Bootloader" and uninstall those device drivers...
Good luck and hope this helps!

what about the other things I suggested?
Or, so it can be clearer, are you in the System/OS when plugging/reconnecting or in Bootloader Mode?
I ran across the same issue..I followed this video to get rid of the old USB drivers and updated to the new Android driver.. Now my window 10 recognize my pixel 2xl storage completely.
https://youtu.be/Zc_dhxc8iJU
I have this issue before, and after all i got my phone detected. But when i flash it, it say unbootable slot in fastboot screen. After couple onf time, it cant be flashed again and die.... My phone cant turn on in fastboot mode again, it bricked
I had to use the USB dongle to connect a flashdrive to my phone, wait for it to recognize the drive, then unplug the drive and dongle... Then connect phone to PC... Profit!
If anyone is still having the issue of PC not recognizing device in fastboot, please be sure you have UNinstalled the older version(s) of SDK Tools from yhour PC and make sure to INSTALL the latest versions.
You can find the latest version linked in the 9x guide in my signature.
Also, make sure you have both older and newer USB cables handy. The Pixel has a nasty reputation for being finicky with USB cables, try diff cables and different USB ports on your PC.
There is also a basic troubleshooting guide in the same link in my sig.
Best regards!

So…without you being too definitive…it seems that you’re able to get into your OS…
What I’d like you to do is uninstall and remove Google usb drivers on your computer. Then, download it again HERE: https://dl-ssl.google.com/android/repository/latest_usb_driver_windows.zip . And, in case things don’t work out this time around, if you can please save the (.zip) file on your Desktop or root folder (usually the C: drive). I might have you direct the device detected to the files in this .zip directly.
Then, after installing the USB drivers, I’d like you to uninstall and remove any/all things that are named “platform-tools” (so there will only be ONE "platform-tools" after you re-download it in this step) on the whole device. After, I’d like you to download the latest Windows version HERE: https://developer.android.com/studio/releases/platform-tools . Again, to simplify things, if you can extract it either in your Desktop or root folder (C: drive).
Again, like I mentioned before, I would like for your device to request authorization for your computer again, so if you can please go to the Developers option, and select “Revoke USB debugging authorizations” as well as double-checking you have "USB debugging" enabled…
Only THEN, once these two things are extracted and installed (as is the case in the first step) and you revoked the authorizations, can you plug in your device and USB cord. Watch your phone/device, as it will ask for authorization to connect to your computer, and you’ll have to make sure the box is checked that says “don’t ask this every time” or “remember this device” – I can’t recall off-hand – and then make sure to “Allow” it. By doing this, you can be sure that your computer and device are talking correctly.
*One suggestion that isn’t mandatory is that you select where it says “USB charging” and change it to “MTP” or “file-sharing” (sorry, again, I can’t recall specifically off the top of my head…)
If all things are working well, if you can open up a command prompt (a.k.a. “cmd”, and also make sure you are running it “As an administrator”) and direct it to the platform-tools directory (hopefully you followed my suggestion and kept it simple so it will either be at the root “C:\” or on your Desktop “C:\Users\[username]\Desktop” so it won't be too difficult directing it there...), and run the commands
Code:
adb devices
and
Code:
fastboot --version
.
Hopefully, if you do all of these things, it might get things reset and working from a stable established set up.
If it somewhat works, but the device in your "Device Manager" is showing up something "funky", then it'll take a rather nuanced Windows troubleshooting technique to resolve where I would have you correct the wrong entry/driver in the "Device Manager" and have it specifically point to one of the contents of the .zip files; shown prior.... We'll tackle that if need be and if all this initial beginning troubleshooting doesn't pan out...
Let me/us know how it works out, good luck, and hope this all ends up being helpful…

thanks for ur explanation, and i'm sure i already did this 100% as you mentioned before. looking for solution and i found this at pixel community thread : https://support.google.com/pixelphone/thread/14477635?hl=en
and btw when i try to disable and back to enable (again) USB debugging, there's no pop up or something like that, just nothing appear. so i just realized why i got error code : 10 is just because my phone still not detected by PC also i tried in other computer (with windows 8.1 installed) my device is got detected but as "device descriptor request failed" not as an android device. Hopefully next update google will fix this "bug". Once again thank you very much

Yeah...I figured as much...I was just making sure to lay down the "ground work" before proceeding...
If you're still willing....what I had planned next was to walk you through manually updating/"editing" the driver (on the PC) to directly look at the Google usb drivers specifically to try and get around the whole "device descriptor" and other (detection) error codes.......
Might want to try uninstall the SDK toolkit, reboot PC, then install the latest SDK toolskit.
Also having both USB 2.0 and 3.0 cables saved me more than once, and is a known thing on the 2XL.

adb fastboot not seeing device

Sorry for noob question. Searched Searched xda and can't find anything. Pixel3 xl. Stock Android 10. Rooted. Windows 10 with correct drivers so it sees device. Can transfer files easily. USB debugging enabled. ADB and Fastboot do not see device. Used to work but not now. Tried kill-server and start-server in ADB. Tried different cables, restarting phone and computer. No luck. In fastboot mode (on phone) fastboot devices returns nothing. Totally stumped. Can anyone help. Again apologize for noob question but this has always worked before and I've flashed roms as well as stock numerous times with no issues till now. Help!

Thanks. Did that. Same thing. Blank list.

I think the easy step to determine if it is a phone or computer issue is to at least try from another computer. The one thing that did just occur to me would be to make sure you are using an A>C USB cable and A port and not a C>C with a C port. The Pixel series has tons of problems with C>C.
Have you recently updated and not re-authorized your phone?

Thanks. Don't have another windows computer to try on. Do have an old Mac and it works on that, just not my windows laptop which is what I use. I have no idea what's making this happen. Computer sees the phone just fine.

Turned usb debugging off then back on again. When I plug in a cable I reauthorize usb debugging but get the same results.

To my previous comment, are you using an A>C cable or the C>C that comes with the phone/charger? Besides that, it still sounds like it could be a driver issue where it is recognizing the phone as a generic USB storage device.

I'm using an A-C cable. Same that I used before when it worked. I thought it might be a device driver too but when I plug the phone in the computer immediately sees it and if I open device manager the phone is seen as an android device.

If you boot to the bootloader and plug the phone in, does Windows recognize it then?

OK, thanks. One thing I can think to do is delete the driver, reboot the phone and computer and then plug in and start over. Make sure to use the Google device driver from the developer page.

No. Tried that first thing. Fastboot devices turns up nothing.

Believe it or not I already did that. I've tried everything with no luck. As I mentioned I was always able to use it before with no problems then this started when I reinstalled a fresh copy of windows.

just for the heck of it, do you have other cables. Stranger things have happened that made a difference, and the next suggestion involves reinstalling computer and/or phone. Maybe a live USB Ubuntu disk to see what is working and what is not.

I understood fastboot devices doesn't see it, but does Windows show a driver installed for it? I strongly suspect you don't have (the right) drivers properly installed.

Yes. Windows shows a driver installed and when plugging it in identifies it as a Pixel 3 XL.

Do a search for fastboot, if you find more than one delete the one that is not in your Platform-tools folder.
Did you give fastboot execute permission?

Only one instance of fastboot. Not sure what you mean execute
permissions. You mean on Windows or on the device? Windows has execute permissions. I don't have adb or fastboot on the device.
