really want to avoid that… ill ring samsung today and see if they can help… ugh hope they are competent and don't waste more of my time!

They wont advise turning on usb debugging

ha! they went a step further to dismiss the option even exists… ugh.. should have stuck with apple, major problems if a consumer that has had an android device for 2 weeks and knows more about it than the 'Samsung Expert'
Called them on the phone too, said it was working and he had no idea why it wasn't on mine. that was literally it…

I just had the same issue.
Turns out the problem is having a Knox container - USB debugging was permanently disabled until I removed MyKnox from my phone, so it would appear the two are mutually exclusive.

Reset my device, which allowed me to switch on USB debugging, but noticed I lost it shortly after setting up Knox again. Removing it brought it back, so I guess that this is working as designed.

ahh ok.. funnily enough there was a guy working for samsung in an EE shop (oxford street, london) and he was super puzzled. he was showing me on his demo phones (which he explained about 15 times that it was a fake phone and not a real one, took me about 20mins to figure out what he was saying. its basically a phone without the calling features..).

Forget Password
Hi guys, it is possible to turn on debugging mode if the phone is blocked? i need some audio records from my s6 edge but i forget my password. and i don't want to do the hard reset because i really need the files... or if y do hard reset if i use dr.fone or something else it is a way to recover the deleted files?

usb debugging popup screen
I can activate USB debugging but i won't get the popup screen when I plugin mine usb cable, the Phone connects to the laptop. I can get files from the Phone to the laptop and from the laptop to the Phone but that's it

Galaxy s2 I777 Does not connect in USB Mass Storage mode.

Hello everyone,
I am a new user of galaxy s2 i777. I have been trying to connect the phone in usb mass storage mode.
I have gone through a lot of threads in this forum, none of them give a clear idea as to what to do.
some say install kies some say something else... I have tried many things. all of them dont seem to work.
Can anyone please guide me in a clear cut was as to what to do?
Thanks guys.
Out of the box, by the default, when plugging, usb icon will and should be displayed on the notification; pull the notification down then tap to connect the usb mass storage mode. Your PC should recognize it now.
Note: try more than one usb port.
Go to settings->wireless and network->usb utilities follow instructions
I ran into that problem after using one my sisters chargers when i was visiting my parents house. Apparently the usb cable bent the connector in my phones port. I ended up bending it back and it has worked like a charm since then
Or enable USB DEBUGGING option. If you do that as soon as you plug into any computer, the option to transfer files will automatically show in your notification/status bar.

To clarify:
The Galaxy S II defaults to MTP mode (media mode, similar to iPhone).
Unlike said iPhone however, we can change ours back to the UMS (USB Mass Storage) mode by enabling USB debugging.
I never found it documented anywhere, I just ran into by accident when enabling USB debugging for TB and MTP stopped working.
It took me a while to figure out why.
I actually like MTP mode (it's faster and easier to use, except in linux as I understand).
The "USB Utilities" option seems to be a per-use setting (not 100% sure, never used it). However USB debugging is a "set and forget" option.
Use steps I quoted above to enable it.
After that when you plug it in, you can select to mount it to the PC via the notification bar.
Hope that helps.
EDIT: It looks like this option was posted by at least one other person on here before: http://forum.xda-developers.com/showpost.php?p=20204599&postcount=12
Tried everything
Guys,
I have enabled USB debugging mode as you have recommended and and it still does not work. I am always getting the notification on windows as "USB device not recognized".
I have tried everything. i have installed the USB driver for I777 from the samsung website. That did not work.
Another strange thing. I tried "Wireless and Network>USB utilities>Connect storage to PC" on my FRIENDS computers(Windows 7), it works.! My phone connects in mass storage mode and I am able to transfer files as usual. I did not install any software on my friends computers.
But when i do the same thing on my WINDOWS 7 PC, it does not work. I use a Lenovo T420i with factory software installed.
I am a noob in the drivers department. Can anyone please tell me what to do.
Thank you.
Help appreciated.
you say "new user" which implies stock rom. if what they are asking you to do is not working, then i believe you might need to exchange the phone. if you have an ICS rom on it, then i think that you might be stuck with MTP until you switch back to Gingerbread. i might be wrong.
Is Anti-virus disabled on your computer? Seems I've heard that it should be, but can't find where... Also, there may be different drivers for a 64-bit machine (W7?) vs. 32-bit.
Have u tried a different USB port or cable on your PC?

Firstly, it's how amazing you are. You asked a question and only returns to it TWO months after? Obviously, it doesn't bother you that much.
Secondly, however, we're here to help.
About your friend computer, a. maybe he did install the Samsung USB driver already or b. maybe, at that time, you are using MTP mode.
Anyway, forget about his computer, let's get it work on yours.
I personally think the USB driver that you've downloaded from their website WOULD NOT work. I don't know why but I can tell you that it did not work for me. Give me some times to dig into my files or search again on this site for the CORRECT driver. You can also help me and yourself by continue to search for this on this xda site since I got it from here too.
Thirdly, along side with the 2nd above, do try different usb cables, do try on different usb ports
I can enable the USB mode on my note, but when browsing the phone with my computer (Mac & PC) I can not see the contents of the SD card?
EDIT: nevermind, rebooted phone and is working now.
Resolved

First of all I appreciate the help you are giving me.
I am sorry if I offended you by not returning for quite a long time to post.
I have now resolved the problem and would like to share for everyone's benefit over here.
The problem was not with the software, it was with the hardware. I followed all the suggestions given over here and was in the end convinced that there should be a problem with my motherboard. This is surprising because my Flash Drive and USB mouse all work with my laptop without any glitches. But my phone(i777) and any other android phone would not connect to the computer. It would say device not recognized.
My nook e-reader which used to work perfectly started acting strange, it would be detected but i would not be able to transfer files onto the nook. So now I ws convinced that this was a hardware problem.
So I called up lenovo and showed them this problem via some software where i could share my screen with them. They asked me if a USB flash drive was working and I said yes. They reply saying that everything is perfect with your laptop and cut the call. I was offended , these lenovo support guys would not understand that it was a complex problem.
So I went to a local MicroCentre which had support for lenovo servicing and showed this problem to a technician. He was convinced that there was some problem and got my motherboard replaced . And voila there connects my android to my computer in USB mode..!
I would like to thank everyone for their help and taking time out to post here.
My laptop: Lenovo T420i with i3. looks like this was a case with my laptop only. a person i know has a t420(i5) in which my phone connected without any glitches.
Thank you for your help everyone. Hope to be helpful in return in the near future.

[Q] Phone automounts by default....any advice?

For the past couple of months I've been having the problem that my phone auto-mounts the usb storage whenever I plug it in to the computer to charge. I've done some research and found that Double twist and Winamp apps have automount as a setting, but I'm not running either of those. I'm running speed rom 7.5 as my daily driver. Any help would be greatly appreciated.

Go to settings, and there should be an option that says "Connect to PC".
From there, you can change the default settings or have it always ask you.
doesn't seem like there's any such option in Speed Rom 7.5

Just installed 7.5, and I see what you mean. But however, when I plug my phone to the PC, a notification pops up, notifying me that it is connected to PC and is set to charge-only mode. I still can press on that and it'll allow me to change the modes. Hm.

Yeah thanks for the help, my phone always did that too until a couple of months ago. I'm thinking it might be an app, but i'm totally stumped as to which one.

So I did a full wipe and re-flashed and the problem is fixed now. Had to kind of start from scratch because the problem would come back if I restored data from my nandroid backup, but it's worth it.

[Q] Tablet won't mount via USB MTP or PTP.

Hello guys,
first let me say that while I may be a noob to the forum I am not a noob to the search features and I used it extensively before making this post. However, the problem I have still remains.
My tablet will charge when connected to the PC, but the USB MTP options do not start on the tablet when plugged in. I have tried all of the suggestions, such as, uninstalling the USB drivers on my PC and reinstalling. I have also checked the advanced storage settings on the tablet and made sure that connection as MTP is checked.
I believe this started happening after I rooted my tablet using this method: http://forum.xda-developers.com/showthread.php?t=1474971 But, I'm not sure if that's the issue.
Any ideas???
Any help you guys can give me would be greatly appreciated! Thanks in advance.

Note: Currently running Stock ICS 4.0.4, Kernel 3.1.10, Build IMM76.UELP
No one has had this issue?
Depending on what I've done last. In settings under developers options. I've left the usb debugging box checked or unchecked and when I switch it from one to the other the tab gets recognized.
Try unchecking usb debugging. You'll need to be disconnected from the PC to uncheck it.
Please don't flame me if I'm off base here. I'm just trying to help with my old man memory.

Thanks for your reply, I appreciate it...but I've already tried that a few times...
not having this fixed is getting frustrating!
Update
ok...So I've tried a couple of other ICS deodexed roms and I still have the same issue...The MTP connectivity will not start on the tablet...
Could this be hardware issue?
Not sure on stock ICS,I hated it and flashed cm10 with pershoot kernel,after that I had the same problem as yu,try Settings>storage>three dots on top right corner of screen>USB computer connection>enable media device....worked for me,I also had the debugger checked off....Or if that isnt it,Bad usb cable??? (EDIT) No go for me ethier,I can only mount the PTP part,not the USB storage
Thanks for your input foxcartman, but I already tried that and it still doesn't work.
more troubleshooting...
ok...so I've tried some more trobleshooting...
I have an HDMI adapter, which works just fine.
I've also tried an SD card adapter and the USB cable adapter, the tablet recognizes both but it does not read any data. ie: the pictures I had on the SD card.
I'm waiting to get another USB cable to see if that's the issue and I'll report back.
Thank you, my new lord & saviour

Samsung Galaxy S9 Plus - Lockscreen Bypass

Hi,
First of all I am really sorry for the questions and the beginner kind of questions. I really need your help. Your help is appreciated.
Please do not calm me down (is reassure the right english word?)! I just want to hear facts and answers regarding the truth/reality..
I have got a Samsung Galaxy S9 Plus (SM-G965F, Duos), bought in Germany. My Android Version was Android 8 or higher, but I can only guess this part. Maybe it was older than Android 8?
It fell into water (only the bottom part) a year ago and about a month ago i gave it to a repairshop (I know that this was very late).
I did not give my lock screen code to the shop workers. I did not give them any code.
The Bitdefender App (full) was installed on the phone.
As I remembered that there was sensitive data on the phone I took my phone back the next day. Bitdefender has mentioned that there was failed access attempt to my phone. Bitdefender App took one or more photos (I can only see one) of a worker trying to unlock my phone.
I used Bitdefender, so I think the Secure Boot was disabled (I think). Is this important for my question?
The old data (before giving to the shop) was on my phone, no deletion of any file, as far as I can remember my own files.
Questions:
Could the workers of the phone service shop get any kind of access, e.g. by cracking my phone, bypassing or just trying. I mean, they are professionals or semi-professionals. My phone code consisted of four digits I think. There was no SIM-card inside the phone.
When I took my phone back the date was set to january 1st. Why that? How can that be? The Bitdefender App said that the photo was taken on 2018-01-01, 15:41 o'clock. Maybe Bitdefender takes it from the android system. Or from WiFi of the shop? Is that possible for them to connect to their WiFi without the lockscreen code? Can it be, that they unlocked the phone, and messed up the timestamp?
Is access (if possible) only via USB cable possible or wirelessly, too?
After a bit of investigation I found out that there is software to rescue data both from iOS and Android systems (For example: Dr. Fone). Maybe access it possible with software like that?
The warranty void of my phone is: 0x0. So I think that software like CWM or TWRK was not installed on my phone, am I right? And I also think that my phone was not rooted, am I right? But I have read that you can flash the full ROM, to set it back, from 0x1 to 0x0 (https://c.mi.com/thread-1898682-1-0.html)
I have read this, but I do not know if it works on my phone: https://forum.xda-developers.com/showthread.php?t=2437946
Could they have gained access to any password, including Google and Samsung accounts?
I have researched and found out that there are several options: USB debug mode, Warranty Void, FRP Lock, OEM Lock, KG State. Do they use one of these to gain access?
After taking back my phone from the shop I did a hard reset on that phone. After the reinstallation the phone did NOT ask me for a PIN/password or google account . So, was the FRP Lock OFF?
I think I had both the Google Account and the Samsung Account logged in on this phone. So was FRP=ON ? What about other options/states, e.g. the OEM Lock?
But I changed the password from within my PC (Browser), not from within this phone. Maybe the phone had an internet connection (so that an error was shown internal on my phone, due to the password change), maybe not. Could the FRP Lock have changed to FRP Lock=OFF (due to this password change?).
What about other options/states, e.g. the OEM Lock?
A bit offtopic, but related to my problem: The shop said that they tested my phone after repairing. Microphone etc. How could they have done that without my lockscreen code? What else apart from microphone could the have tested?
Hi again,
I know that this is a long post nd much to read. I need your help. I have researched and asked, but no definite answer.
Please help me out, guys.
Your help is appreciated!

Hi,
as far as I know you have to enable the Developer Options first, in order to enable the USB Debug mode, right? If it is like that, no. I even never got into the Developer menu I think - as far as I can remember. Because I didn't know about this option.
edit: And the standard option is (e.g. when bought a new phone or after a hard reset etc):
USB Debug mode disabled, correct?
