Connect USB flash drive to Android without root? - General Questions and Answers

Since my tethered connection is throttled can I connect my flash drive to my phone and download over 4G? I have an OTG cable but nothing happens when I plug it into my phone and on top of that I can't find a No Root flash drive detection app to save my life. I thought my phone was rooted but it isn't according to the root apps I've tried. I can't even get those nonworking apps off my phone screen. Anyone know how to do that by the way?

It depens on OS version. For example some cables are compatible with dofferent OS versions, amd appearently it isnt compatible with yours

The device itself has to physically support USB OTG. For USB OTG to work, the device has to provide power to the USB (not just receive charge from). Sometimes the solution to that is to use a powered USB OTG cable (this will have another plug to get power), but even in that case, the device has to have OTG support built into the kernel, which, if the device doesn't physically support USB OTG, it's unlikely to support it in the kernel.
Best bet is simply to download something to the phone and transfer it via USB to your computer.

[Q] USB Mass Storage Won't Connect

I upgraded to Sky-ICS RC7.4 Speed yesterday and today. Obviously the USB mass storage was working earlier because I got the .zip file for the upgrade on the phone. Well, just a little while ago I tried to connect so I could pull those zip files off just to save some room and it won't connect.
I can charge the phone, the laptop(Windows 7) and the phone both make sound/vibrate when connected. BUT, with I go to "Connect storage to PC" it tells me to unplug the cable, which it hasn't before but I did it anyway. I unplug the cable press the connect button again it states to connect the cable, I do. Press the button to connect and I get the same result. I've tried enable USB debugging and try again and it states to disable, blah blah blah.
It's great that I can charge the phone via USB all day long but really sucky that I can't access any of my files via my laptop.
Anyone had this issue or know of any fixes that may alleviate this issue? I sure would appreciate your help.
FYI, USB drivers are installed on the laptop and reapplied after the the issue of not being able to connect USB mass storage...
update: I am able to see the two mounts in computer management on my Windows 7 machine but not able to access them through My Computer.
I was reading from other threads about a possible Windows issue, how I find it unlikely, but I did a system restore from an earlier date and that made no difference. It's still a matter of the phone connecting completely to the pc.
Also tried different ports and usb cables, no avail.
I could really use some input so that if need be I can access the files on the phone to either flash back to stock or at least modify the files I have on there now to let me be able to attach my mass storage. I'm liking the the rom it's just a few little things like this that are making me completely love it.
i have the same issue if i plug in to the front usb ports. no problems with the back and its only been since i updated to seans latest speed stripped ICS rom
I was having the same issues. I turned the phone off, took the battery out, and then restarted it. It worked.

Correct; you need to reboot your phone because you probably connected / disconnected too fast and the phone is bugged out now.
I'm on 7.4 speed stripped and its working fine for me. Did you try installing the Samsung USB drivers exe in the dev forum?

[Q] Android Tablet: Enable Fast Charge/Force AC Charge allways

I need to enable fast charge/AC on USB and keep it enable to communicate via USB. I need my tablet to charge as connected to AC and be able to transfer files in the same way as if I connect to a PC.
I will have a AC adapter in the middle powering the device 5V/2A, so I wont burn my PC USB port (I wont drain any power from the PC, just the D+/D-/GND Lines...). I know that I should not connect the tablet directly to a PC once I do this.
I have my device rooted, but I do not want to use a custom kernel. Is there anything I can change on my kernel to do this?
Once I think I saw some change that I must do in a system file to be able to do this, but I'm unable to find it now...
Thanks for any tip,

USB Problems

My computer for some reason reminded itself of not recognizing my Idol 3 5'5 6045k. Two days ago it was all fine and now everytime i connect it to the computer it only charges. I've tried everything from changing usb cables to unistalling andthen installing the device drivers, enabling debugging, restaring either smartphone and computer. Everything I can think of. Please help me out, I'm trying to root the smartphone and without it recognizing I can't do anything, not even transfer files. :crying:

Obvious Question #1: Did you check the phone notification dropdown area to verify the phone is in MTP or PTP mode so it will show up on the pc? As for transfering files...you do have the option of loading up a microsd card with whatever files or installing a wifi adb app to connect wirelessly. You could even use an app like airdroid to let you do all sorts of things.

Therre's no notification after connecting the usb, it just charges the phone, seriously, I've tried everything to enable MTP but nothing does the job. And what do you mean by using an adb app? Can I root my smartphone by a wireless connection?

You are overcomplicating things. 1st...there is ALWAYS a notification in the dropdown that says what mode the phone is in....mtp, ptp, charge only or "cdrom mode" which installs the usb drivers. Pressing on that notification allows you to change the mode the device is in.
As for rooting....all you need to do that is to flash or boot TWRP (details on booting it are in the system image thread) and then flash the supersu zip from inside twrp to your device...reboot and done...but I think in the newer TWRP's they even offer options to root automatically...ie the zip is already built in. After rebooting to your phone you install the supersu apk from google play so you can configure what apps have superuser access.

Your telling me when the phone is plugged into the pc you don't see the notifications below or some version of them at all? If so then you need to fully uninstall the devices in device manager including remove the drivers...then use the drivers in the system image thread (since you obviously can't use the ones from "cd rom mode" which would be the best solution). USB debugging isn't even an issue yet...your phone should still show up to the pc as a camera device (ptp) under just about ANY scenario using even built in windows drivers.

Thanks for all those tips, but I already tried that out aswell, 2 times to be precise, deleted all the drivers, rebooted pc and smartphone, tried different cables, but still nothing ever occurs.

Have you tried a different cable? Perhaps that one is damaged or is only setup for charging? Only thing I can think of.
And then I realize you mentioned that Not sure what else would prevent it from giving you those options.
I'm also facing similar issue after the 2 update. Were you able to fix this?

Which kind of USB cable(s) have you tried specifically? Were they cheap eBay/generic kinds or well known branded ones?
Something as little as a Micro USB cable can cure a lot of problems. It needs to be a well built one by a known manufacturer to avoid problems.

Actually I've been having pretty good luck with the $1 ones from Dollar Tree but the key is certainly to try multiple cables....on some the microusb plug will make it difficult to get a solid connection especially if you have a case on the phone.
You may be missing the point of "trying" different cables. It's not so much the "quality" of the cable, it's the fact that some cables are for "power only", and "will not" transfer data, regardless of how hard you try.
You need to be using a "proven" data/power cable, otherwise your beating your head against the table for nothing.
Just to add, I put a piece of red tape on all my usb cables that are power only, no guess work.
I own idol3/moto g 2015 and s3, have no problem with other 2 device. I'm having this MTP issue after the UE40 update. Verified in all 3 OS, adb is detecting the device but not MTP/PTP. Idol3 support is not worthy responses.

Well, USB works fine here, and I've had 5 different rom's, 2 Canadian, 2 US, and the Chinese rom, on this phone without any USB issues, sorry, can't help any further.
After a complete wipe and restore, it worked.

I had the same problem as well. It only showed charging when I plugged in the USB cable. Tried switching cables, turning off and on USB debugging but nothing worked. I finally just rebooted the phone and then it worked again. Strange that it suddenly stopped.
I have a different issue; the different USB modes work fine but I don't have the 'cdrom' option in the USB mode dialog. I've tried various Alcatel ADB drivers that I have found and none are working, using Win7 64. My Idol 3 4.7 is 6039I (US).
Answered my own question, simply install the Mobile Upgrade Q software.
nope, doesn't show up. it's a bug. i had it before, googled until i found a fix and got it working, now it's back to not being recognized. nothing shows on drop down menu.

Question Phone no longer being recognized by computer. Not even getting a prompt on phone when plugged in.

As the title states, my phone is no longer being recognized by my computer when I plug it in. I've tried multiple cables, multiple ports on the computer, both ports on the phone, factory resetting the phone, uninstalling and re-installing drivers on my computer, booting to Ubuntu so I wouldn't need to worry about drivers. Nothing has worked. I'm not even getting the USB prompt on my phone when I plug it in. It DOES charge but I'm not able to transfer files, adb or anything. ASUS wants me to send the phone in but I don't want to go who knows how long without my phone, plus I don't think it's right that I have to pay to ship it when it's their phone that is ****ting the bed. Could anyone PLEASE help me? Thanks.

If your phone won't connect to the computer using the USB cable, then the FIRST thing most people do you've done, which is switch cables and rebooting the phone (factory reset is extreme but you did that also).
The second thing most people do is install the manufacturer's drivers, which you also did.
The third thing you can do though, is connect the phone to the computer WITHOUT the USB cable (i.e., over Wi-Fi) because that will work even if your phone port is broken and even if the USB cables are bad and even if the drivers aren't on the computer.
Below are screenshots of just some of the ways to connect the phone to the computer over Wi-Fi without any cables, and if you want, you can follow one of my tutorials on the subject.
Hope this helps.

Would I still be able to adb using the wifi method? My main issue is trying to remove the old Google Pay app. Which I'm unable to unless it's through adb.
Just an update. I was, in fact, able to run adb commands while connected using wi-fi. Thank you @GalaxyA325G for your input.

Not sure what to tell you about your signal dropping, but
is the video I used to finally use adb via WiFi.
Have you tried clearing the adb authorizations (in developer options) with the phone disconnected and then connecting? Sometimes a change can trigger the phone to stop recognizing the computer as allowed without treating it as a new connection.

Question S22 ultra samsung dex

My s22 ultra suddenly does not work on dex. Theres no way to access the sd via a pc either.
I was using this exact setup and it worked fabulously.
As far as i know i went to bed one night and it didnt work the next time i went to use dex.
Reboot phone and pc? Is the phone recognised when connected? Try another cable, does it work on a different pc. Do other USB devices connect ok etc etc
i have rebooted both phone and pc. Same cable as when it did work infact the samsung original that came with the s22. My s9+ does not connect. Both phones DO charge via usb c.
I have infact reinstalled my pc and resest my phone to factory trying to fix this.
Still to no avail.
Does it connect to another pc? Usb pc hub might have failed
its a brand new laptop and it does power the phones. and it all did work fine. i can even power my usb c vape through the same port
there is not an alternative machine to test on
actually i just thaught of this, the last night i was using it i had the standard popup on my phone asking to allow dex to run. An ok responce and cancel or not now responce, i dont remember exactly.
Could this have done something if i hit cancel
also could there be something in the pc bios i may have not realized could effect this. Since i was on the same night trying to boot to a usb linux pendrive
When you connect your phone can you access its files on your pc? Is it recognised as drive
Ok so ive even reset the bios to system defaults and tried a regular usb to usb-c and still nothing

could it have anything to do with the phone usb connection settings. When you plug in a usb otg it normally would give an option for transfer or charge etc on the phones pull down menu and all its doing is saying fast charging
Try phone on another pc
Absolutely everything else works through usb mate.
What else can you access via USB. Drives, devices?
well i can access the standard usb port with an sd card reader. read write and even installed windows off it. So this usb to usb c should work fine.
If it were just the usb c hub blown this would not be the case.

im currently trying to see if i can run a lubuntu through usb bootable key and try to access the usb c ports from that.
I have been reading about my laptop and apparently it has a reputation of usb issues. lenovo x1 yoga gen 2 on win 10
Solved. During a bios update it appears the bios setting for thunderbolt usb-c was changed to disabled. As soon as i discovered this and rebooted it worked so if anyone is having issues with this they may want to check there bios settings.
4 days of struggling over. Dang its nice to beat a computer once in a while.

Do you have Link to Windows enabled on your phone? If so, turn it off and try running DeX.
