[Q] ADB Installer Issue - USB Connection

Hello, another question in quick succession.
I have used the installer featured in this topic: http://forum.xda-developers.com/showthread.php?t=2588979 - to install all the necessary drivers so I can connect my phone through USB and hopefully install Android 5.1 onto my phone.
I went through every step in the topic and ADB Composite Device appear listed. My phone is also definitely connected as I check for 'adb devices' in command prompt. However, when connected in fastboot mode, it still asks to Connect to USB Device. USB Debugging has been enable on my device, also.
Help would be much appreciated! I'm new to this so it's a teensy bit of a rigmarole.

Could really do with help here, I'm stalling on it and it's bugging me - wanna get it sorted.

[Completed] USB Debugging device unathorized

Hey guys,
got a massive problem: When connected to both my PC and Surface Pro 2, I cannot get the RSA popup working on my Nexus 5 (Mashmallow) when using ADB. The device just gets listed as unauthorized, no matter what I do. I tried with Minimal ADB and Fastboot, Nexus Root Toolkit, official ADB, Google ADB drivers, Universal and Naked.
Is there anything I overlooked? I also disabled driver signature on Windows 10, to make sure it's not an issue with the ADB drivers.
MTP, charging only and PTP all won't get the RSA popup working, so I just cannot authorize the device for USB debugging.
HALP!!!!

Fastboot will not detect my device while rooting

I've been trying for the past couple of days to root my Oneplus One. I started with this tutorial: (http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471) which is featured in the FAQ (which I've read through) and I've gotten stuck at one location.
You can test fastboot by connecting your device to your PC while booted into fastboot mode (power + volume up) and issuing this command:
Code:
fastboot devices
It should return your device serial number, if so, fastboot is working.

The ADB command appears to be working, but when I boot into fastboot mode (and when I'm not in it as well), the PC does not detect the phone. I've tried connecting it to multiple USB ports, and I'm using the official Oneplus One cable, so I'm at a bit of a loss of what to do.
However, I feel like I've identified where the source of the error is. If you see here: (http://i.imgur.com/IE1Bxjs.png), you can see that the phone is being detected under Portable Devices. In all of the tutorials I've looked through so far, it's been detected under something like "Android Phone" or "ADB Interface". I've tried various things to fix this, the most common of which is installing drivers onto/for the phone. I've tried the one here: (http://forum.xda-developers.com/showthread.php?t=1413293), which I know is for Archos phones, but should work similarly, as I tried both the Universal ADB driver and the Google one, from the SDK Manager. I kept getting an error telling me that: "the folder you specified doesn't contain a compatible software driver for your device."
I've also tried the one here: (http://www.makeuseof.com/tag/android-wont-connect-windows-adb-fix-it-three-steps/) (let me know if external links aren't allowed and I'll remove it.) This doesn't seem to work either, as I get this error (http://i.imgur.com/CLATXsl.png) when it tells me to:
If you cannot get any driver to work, you will need to force installation. Instead of choosing “Let me pick from a list of device drivers on my computer” in the previous step, you will choose “Browse for driver software on your computer” and manually find the directory where you installed Koush’s drivers.
The location on your hard drive looks something like this:
C:\Program Files (x86)\ClockworkMod\Universal Adb Drivers\
Windows will then install the drivers. From now on, whenever you connect the Android device with debugging enabled, Koush’s drivers will load in place of the ones that failed to work.

And now I'm posting here, praying that someone will have some sort of idea what to do. Any help at all would be greatly appreciated,

EDIT: Managed to get it working, messing around with the drivers in device manager while in Fastboot mode seemed to work.

Feel your pain, I've been thru some pain myself with some weird issue, posted here yesterday. Though, my issue is different from yours, I have some ideas for you.
You say that adb works, so I assume your usb cable & PC are OK here.
I aslo assume that your Device Manager screenshots taken when connected to your phone in device mode (rom running). Don't worry about what you see in Device Manager just yet. Your goal is to make fastboot work, right. Note: Adb works in recovery mode and device mode, but not in fastboot mode. Fastboot works only in fastboot mode.
You could try this, put your phone in fastboot mode, then connect to your PC. Now, see what in your Device Manager. In my case, the phone is under Android Device>Android Bootloader Interface and I use Google driver. Then, try "fastboot devices" to see if your phone is detected.
If not, play with the driver in Device Manager (uninstall, rescan, install another). No need to unplug the phone. After the driver changed, see your Device Manager changed, and then try "fastboot devices".
I played with the driver changing a few time and got fastboot to work. I hope you get it to work too.

Galaxy S5 with broken screen, need help controlling it from PC

Hi, I've got an old S5 with a broken screen. There's no image going on and there's no indication that the touchscreen is working.
I'm not looking to recover data, I'm looking to play around with it by controlling it from my PC. Last I remember, the phone is running a Cyanogenmod OS (I don't think LineageOS was around at that time) with either TWRP or CWM recovery, but I'd bet on TWRP.
Now: the device reaches the OS properly, I can tell because if I try to turn the ringing sound up it gives me an audio feedback.
If I connect it to a PC from the OS:
- the phone shows up in Windows Explorer as "SM-G900F"
- Device Manager shows me a "SAMSUNG Mobile USB Composite Device" under Universal Serial Bus controllers
However I cannot access any files (Windows Explorer shows the device as empty), and if I attempt to 'adb devices' in the console it shows me an empty devices list.
Now, I suspect that USB debugging might be off. So I also tried connecting it to a PC from recovery and the exact same thing as above can be observed, PLUS:
- Device manager also shows me a "SAMSUNG Android Phone" list which can be expanded to show me one entry called "SAMSUNG Android ADB Interface"
However it's the same as before, no files available and 'adb devices' shows an empty list.
Now I heard that I can theoretically enable USB debugging through ADB, by writing to a config file. That would allow me to enable USB debugging and try something like Vysor in order to control the phone from my PC.
However that's a moot point until I can figure out why the ADB service on my PC isn't seeing the device. Any help would be greatly appreciated, and if you need more info I can provide it.
Extra info:
- I installed Samsung USB drivers at some point while trying to make it work
- Windows Explorer shows a phone icon for this device, and if I recall correctly that's what happens when it's connected through MTP (Mass Storage should show it like a memory card)

Thanks a bunch, that pointed me in the right direction with my research! I solved my issue, I can now control my phone from my PC.
By doing this I ran into a couple of problems, I'm going to describe them and their solutions:
Problem 1: couldn't ADB into the device when in Recovery Mode. That is because after a long head scratching session I came to the conclusion that I didn't have TWRP Recovery installed (I had Philz Touch CWM Recovery and LineageOS 14.1 instead).
Solution 1: ADB mode is enabled in TWRP by default. So I flashed the latest TWRP through Odin, ADB instantly started working afterwards in Recovery Mode.
Problem 2: USB Debugging was disabled inside the OS.
Solution 2: from the thread that Ibuprophen posted, you can enable USB debugging in your OS by opening an ADB shell into your device and modify the build.prop like so
Code:
Adb shell
echo "persist.service.adb.enable=1" >>/system/build.prop
echo "persist.service.debuggable=1" >>/system/build.prop
echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop
reboot
Problem 3: /system was empty so there was no build.prop. If I attempted to create a build.prop file it wouldn't be saved after a device reboot, so USB debugging still didn't work.
Solution 3: it seems like TWRP doesn't mount /system by default, only /data. You can mount it manually through ADB like this:
Code:
mount -o rw /dev/block/bootdevice/by-name/system /system
I found this out from this stackexchange question: https://android.stackexchange.com/q...data-partitions-in-recovery-mode-in-adb-shell
Problem 4: When an app tries to use USB Debugging you need to allow it to do so from the phone. Since the screen was broken, I couldn't do this.
Solution 4: You'll need to push a public key to your device with ADB. Boot into Recovery Mode and make sure your device is recognized by your PC and type
Code:
adb push <path to adbkey.pub on your PC> /data/misc/adb/adb_keys
This solution is from: https://stackoverflow.com/questions...b-rsa-key-with-broken-touch-screen-on-android
This will make sure that you won't need to confirm debugging permissions for apps coming from your machine.
So for anyone who has a broken phone screen (my screen is dead and touchscreen/touch buttons are kaput too) and wishes to control their phone from their PC but USB debugging is disabled:
1. Boot device in TWRP Recovery (flash it if you don't have it)
2. ADB into the device
3. Make sure /system is mounted (if it's empty it means it's not mounted), else mount it manually like in Solution 3
4. Configure build.prop to have USB Debugging enabled like in Solution 2
5. Push your public key to the device like in Solution 4
6. Restart the phone (into its OS)
7. Download the Chrome extension called Vysor and launch it
8. Connect your phone through a USB cable
9. The device should appear in Vysor, connect to it and have fun controlling it
Note that if you just want to backup your files, steps 1 + 2 are sufficient. After making sure ADB works you can just 'adb pull' all your files which should be located in /sdcard. Google it, it's easy to find.
The same goes for backups, you can do them directly through ADB.
Again, thanks Ibuprophen!

Vysor does not work on all graphic cards. a good free alternative is scrcpy
btw instead of flashing twrp, you can flash a modified system partition with proper entries in build.prop (for those with no custom recovery available)

Bloatware Apps Removal via ADB

Hello Everyone,
I would like to learn how to remove bloatware Apps from my Android phone.
I have tried using "ADB commands" but for some reason my computer doesn't recognize/find my Android phone when I connect it to it.
Please help.
Thanks in advance

Download drivers for samsung and enabled adb developer option then type following "adb devices" press enter and should see serial number indicating phone connected via adb

Hello, and Thanks
I have done that exactly, but it still doesn't work.
And I can't figure out why is not working.
I have installed the Samsung driver, allowed the ADB function on my phone from "Developer Options" etc.

In addition to the advices by petiolarissean , check whether the driver works well, please.
In the 'Devices Manager' of your Windows, check the driver for your Android phone.
If this doesn't work yet, change an usb cable and then try again.

Only to have mentioned it:
So-called bloatware typically is housed in Android's locations /system and/or /system/priv--apps what only can get accessed by Android's root-user after successfully mounted as RW.
