Hello,
When I plug my phone into a computer, it automatically enables data sharing either via MTP or PTP. I have no option to NOT share with the computer (or device) that I'm plugged into. For security reasons, I want USB to be in charge-only mode unless I specifically select a data sharing mode. My older Android phones used to work this way, but it seems that someone in their infinite wisdom decided to remove this critical functionality. Is there any way to restore it?
Currently, I am using a power-only USB cable to achieve this, but it is only a workaround and doesn't address the bigger problem. Frankly, I find it a little ridiculous that I can encrypt the device, but anyone can just plug a USB cable into my phone and grab whatever they want off the phone.
I've read that something like this can be achieved by forcing the kernel into Fast Charge mode, but I wasn't able to find much information on this, and I'm not sure if it's even possible to do on the Stock i337 TW kernel. Any help is appreciated.
Phone specs: i337z KK 4.4.2 SHOStock SS ROM
Thanks!

Just rooted using this method:
http://forum.xda-developers.com/showthread.php?t=723479
When I hook up the USB cable, it no longer shows up on the phone and gives me the option to mount memory card.
How do I go about fixing that?
(and also, should I need to, how do I unroot?)
EDIT - Now works after reapplying USB settings, weird.
Re Root the phone with one click. If you cannot mount to the computer etc. then odin back to stock and then reroot, You are not the first person to use this rooting and have this happen. Not sure why may be just a batch of phones this method doesn't work with.......
I had the same problem and solved it by allowing USB Debugging mode. When you use ROM Manager and CWR, it actually tells you to leave the phone in the USB Debug mode, maybe the connections issue is the reason?
Hi, I'm really hoping someone can please help.
I accidentally dropped my 2012 Nexus 7 and now the touchscreen won't work. I am trying to backup the data. The tablet turns on and my PC recognizes it when I plug it in via USB. However because I have a passcode on the lockscreen Windows won't show the files on the tablet until I unlock the screen. This is no doubt a security feature. Is there any way possible to either bypass the lockscreen or access my data another way?
I tried using SkipSoft Android Toolkit but for every option I select it says "Waiting for USB debugging to be enabled".
2012 Nexus 7
Android 4.4.x (Can't remember if it was running 4.4.1 or 4.4.2).
Everything is stock, no root.
Bootloader version: 4.23
The problem is that USB debugging is not enabled on the device, so I cannot use adb. Is there any way around this?
Any help is greatly appreciated.
Thanks
For anyone who might be caught in a similar situation, I was able to enter the pin code via mouse and OTG cable.
Okay, here's the situation. My girlfriend dropped her S5 and the screen cracked. At first you could see part of the screen, but overnight that stopped working and it's completely black now. The digitizer kind of works, I can unlock the phone but don't know where to go from there. All I'm trying to do is restore her apps and app data to her replacement S5.
I've tried the following:
A. Backed up the the broken screen S5 via both Smart Switch and Kies 3, but for whatever reason both programs do not allow the apps to be restored to the new S5. In one of those programs it mentioned apps need to be installed first before restoring, so I tried installing a couple of apps on the new phone, but still the app restore check box in both smart switch and Kies is greyed out.
B. I pushed sidesync to the broken phone and can see that it is installed from the app backups in both smart switch and kies, but I can't open it on the broken phone so I can't get the virtual screen to work.
C. USB debugging is NOT enabled on the broken phone. I tried blindly navigating but I'm not even sure if I'm getting anywhere.
D. Bought the Samsung USB to HDMI adapter cable. I can get it to work with the new S5, but don't get a signal when connecting it to the broken S5.
My approach so far is to try and get USB Debugging enabled. Then I could use one of the Android virtual screen programs download and run Helium to backup apps and app data, or try a 3rd party Android Transfer PC program (tried one but requires USB debugging). Here are my questions that hopefully someone can answer:
1. I read somewhere that you can enable USB debugging by flashing a custom kernel that has USB Debugging/ADB enabled. Would it be possible to modify a stock NK2 kernel so that it has USB debugging enabled and then I could then flash the modified NK2 kernel to the broken S5? It is recognized in Odin and I'm fairly sure I can get it into Download mode.
2. Would taking apart the broken S5 allow me to possibly fix/mend whatever is broken or disconnected and preventing the HDMI cable from working?
3. Is there some way to restore Apps and App data from the Kies 3 or Smart Switch backups to the new S5? It seems very strange to offer backups of Apps and data in in both programs, but not allow them to be restored to the same make and model replacement phone.
If anyone has any ideas please let me know, I'm willing to try anything. Thanks!
Notes:
If I had done any of the following I could have avoided this mess. (1) Turn on USB debugging (2) Run Samsung sidesync at least once on the phone before it broke, it seems to automatically start if you've gone past the intro screen once. (3) Backed up apps and data via Helium (her phone was not rooted).
So as the title says, I recently lost control of my phone and in a panic full wiped everything. I figured this wouldn't be such a big problem as the hardware was fine, however, I'm now realizing that without developer mode and usb debugging enabled I can't do ANYTHING. I've tried to reflash stock via adb but the device isn't recognized, likely for the above reasons. Under normal circumstances I would just plug my phone into my computer and use MTP to move a rom over, however since the default mode is USB charging and I don't have have an OS installed, it seems I can't change that.
I've been told that it's essentially impossible to brick a nexus nowadays, but I feel like I somehow managed and for the silliest reasons. . Someone please help.
Edit: I should mention that I still have access to TWRP somehow.

While in TWRP, use ADB Sideload and install the latest OTA zip from Google:

Edit: How did you reflash stock? Because you should be able to do the above, ADB push, or drag and drop via TWRP. You may have to mount the file system before doing so.

USB OTG pre-populated with a ROM maybe?
I have a g930v that I need to get U or T firmware on for wifi calling. Problem is the USB is apparently bad. Charges and fast-charges just fine. But when connected to the pc it shows the device is unreconized. Happens on multiple pc, port, and cable combinations, all ov which my Tab S2 will connect with. Is there anyway to flash through ADBlink terminal or from SD card without using Odin or get the PC to reconize the phone (doubt full if the USB port is bad)? Tripping Knox doesn't bother me as I don't use Samsung Pay and the phone is clearly out of warranty and it will be used until it dies rather then traded it. I have file sharing turned on, adb dubugging is on, OEM unlock is on, USB configuration is set to MTP, verifify apps via USB is off. If I manually update the Microsoft generic driver with the Samsung driver I get Code 29 so I now the phone isn't shaking hands with the PC. Any thoughts would be appreciated. Thanks.

either you have to change the USB chip on the system board or change the whole board, changing USB port/charging port wont fix this issues, and you can't flash without odin.

Thanks for the feedback. So it most likely the system board and not the charging board. Bummer. I am going to guess there is a 250% chance that it is a bga layout also. Looks like I'll suffer until I can grab a new phone. Thanks again.
