Hi
I'm quite new to rooting and playing around with roms and kernels. Usually whenever I install a rom on my phone I usually download it on my computer then transfer the zip file into my phone via usb. I noticed a new rom had been released for the P8000 (nexus) and i wanted to try it out so I downloaded it on my pc but I was not able to transfer onto my phone. I got an error message on my pc saying 'could not transfer file, device may have been unplugged or is not responding'. The device certainly was not unplugged as the phone was still charging and I was able to continue browsing through my phone's files.
Have not connected a phone to a pc in ages.. Use droid over wifi!
dunno why that should be but why not just d/l directly with your phone? that's what I tend to do as it's faster than wifi transfer and my pc drivers don't seem to work with my p8000 either so can't connect to pc.
try to enable usb debugging (or disable). i had this some times ago with a samsung phone. connection option als camera could help maybe too.
regards
Maxon

I have installed and reinstalled the samsung windows drivers about four times.
My phone has not yet been activated and I'm not sure I'm going to attach it to service for the foreseeable future instead of possibly using it as an ipod touch with a keyboard.
I have connected the phone to my laptop one time. I feel asleep with the phone searching for drivers (the drivers had already been installed but the status bar message said it was searching anyway) and when I woke up it seemed fully connected. I was able to cwm3 root the phone but bricked it I think by putting an ext4 filesystem on without moving immediately to an ext4 rom.
I've restored it to stock and through wifi updated it over the air to ec05
Ever since then I have never been able to connect using any of the usb ports, trying two different usb cables, the oem and a generic micro-usb cable and using either windows vista or ubuntu on this computer.
Clockworkmod reports that the phone is not connected and I am not able to see the phone as a hard drive when I set it to mass transfer mode.
In download mode, odin is able to communicate with the phone reliably.
I've repeatedly tried all ##8778# settings and I've set debugging mode off and on. Device manager shows that the phone is connected to port COM7.
Is it possible that the activation program is preventing the USB connection? I would think not because the activation status has not changed since the one time it did connect, but I'm at a total loss for any explanation.
My next step is to try another computer but I don't have one handy.
Is it possible to root a phone only through odin, or to put a file onto the sd card that can root without the use of the computer?

This thread had a pre-rooted EC05 that you can flash through Odin

Thanks. I'm on ec05 now, so I'm OK with that. I'd like to root either with or without resolving the usb connection issue.
Is that possible at all?

While it isn't JUST a root that you are doing, as stated by budderocks, you can flash the pre-rooted EC05 tar file through Odin, although it will require you to reinstall any apps you currently have. This will start you out with either a stock(ish) setup, with root already included (not sure about Clockwork though), or you can use the one modified for the ext4 filesystem with CWM 3.0.0.6 included which will convert it to ext4 the first time you boot into recovery.

I have been through this myself and came short of beating my head against a wall before reading that it "may" be a cable issue.
Well, after tyring everything else, (because it couldn't be something as simple as changing to a different cable, right??!!) I pulled out an old cable from my Blackberry days and BAM - my laptop searched for and loaded the needed drivers and sees my phone everytime I plug it in now. I have also used a cable from a friends phone (not a Blackberry) and my laptop still sees the phone so I'm not advocating for Blackberry cables specifically.
Bottom line is - the Samsung cable is a piece of crap. It may work for a day or a month, but it will soon (for 98% of Epic owners) become nothing more than a charging cable before long.
Try using a different cable (not a Samsung model ) and see if that works. If so, then ODIN/one-clicks become your best friend(s)!!
Hope this helps!

I've searched google/xda and no one seems to address this very clearly.
I was having problems connecting my SGSIII via USB to my computer(s). Yes, I was using the cable that came with the phone. When trying to simply transfer files via USB (MTP or PTP) windows would not recognize the phone and a message saying "usb device has malfunctioned" popped up from the notification area of the taskbar. I had all of the drivers installed. I tried connecting the phone to my laptop (thinkpad) and desktop (homebuilt) computers, which were both win7 64bit. I tried every single USB port of each computer. Sometimes the device would show up in my computer, but I couldn't access any of the files. I was able to get odin to recognize my phone, however, and (foolishly) tried to flash a rom to my phone. Odin would fail every time at a different point in the process. I was stuck with a phone that would not bootup.
Then, I tried a computer (old dell, win XP) at work. I tried to flash the rom with Odin again. On the third attempt it worked! (after changing to a back (instead of the front) USB port) It was a big relief that I didn't brick my phone. Also, with this computer I could connect to my phone via MTP or PTP. I thought, therefore, that the problem was win7. So, I went back, installed win XP on my computer at home. This computer would still not play nice with the phone. (USB device malfunctioned error appeared again.) So, if you're having problems try a different computer. I had to try 3 before I found one that worked.
TL;DR: Try a different computer and different USB ports on that computer before you give up on connecting your phone to a computer via USB.
Finally, I NEVER had these problems with my HTC Hero, or HTC Evo. The phone would connect to ANY computer or ANY USB port. This was true for transferring files and for ADB also. With my S3 I'm transferring files by removing the SD card and connecting that to my computer. Kind of a pain in the ass. Thanks samsung.
Wow, I would think this would be easy (coming from a Nexus 5), I just plugged in the N5 via USB to my Windows 7 machine and boom, I could browse the phone. Now, trying to do this with my G3, I have installed Windows drivers and nothing. I plug the phone in and nothing happens other than a pop up on the phone saying it is charging slowly. I've searched the LG site and Google and found references to MTP and having 3 options when connecting the phone to the PC but I get none of those options and cannot find an MTP option in settings. All I can find is a Connect to PC which tells me to use LG PC Suite. I really don't want to install some other software. I just want to browse the phone and copy files over. Is this not possible with the G3?
Switch usb ports. Set up usb connection as MTP.
Huh? As mentioned, I don't get any options to select MTP. Drivers installed, various USB ports tried, nothing happens other than a slow charging pop up.
Edit: Seems the system at work for some reason does not see the device properly. Just tried at home on my PC and it's fine. Bizarre.
If it's a work PC, it is possible your system admin disabled MTP completely. Because, you know... security and stuff.
try going on your phone while it is plugged into the pc
Hi All, sorry this is a fairly long post.
i recently "Upgraded" my SM-P605 to Android 9 and it has been working fine.
i have, however, been experiencing connectivity issue with file transfer via USB.
i have tried several cables (3 Genuine) including a brand new "Generic" cable and keep getting the "device descriptor request failed" error.
i have also tried multiple PC's, loaded all recommended Samsung drivers and finally relented and replaced the USB port in the tablet itself, which still did not fix the problem.
Convinced after all of this it must be software related, i then decided to re-install and earlier version of Android which i copied over to the Tablets internal memory.
i logged into TWRP and wiped the tablet ready to reinstall Android 7. and when i tried it says the zip file is corrupted.
i now have a tablet that wont load the zip file i have, wont read from an SD card in the tablet or OTG (via TWRP) and is unable to connect to a PC via a usb cable..
if anyone could offer any suggestions i would be extremely grateful as i dont want to "Dump" this tablet as i use it daily for work..
Why it does not read the SD card? I would expect that should work and should be the safest bet here...
-Maybe the zip file really is corrupt, which can be easily told by unpacking via pc.
-If the tablet can still charge the battery usb is most likely okay.
-Sdcards can fail by becoming read-only. Most easy to tell by unsuccessfully trying to format them in the tablet or pc , but e. g. under Windows you seemingly can successfully delete and copy stuff, everything as it should even after forced refresh via F5. But after reinserting the card or rebooting the previous state is back.
-ADB has been enabled in developer settings? Then you normally get a notification where you can modify usb mode. Charge-only won't work, but most of the rest should do (Dcim/mtp/msp...) .
-And all the time Windows has to recognize the device via PnP and auto-install drivers for the current usb mode. Besides the aforementioned storage drivers for flashing and communication a modem driver and virtual COM ports must be auto-installed.
In this department i had lots of trouble with a phone based on an old TI OMAP SoC under any Windows newer than seven. Only Download mode invoked on the phone itself was still working and only zseful to restore stock rom, while in the more flexible Fastboot mode the phone wasn't recognized by Windows.
Samsung devices seem to support Fastboot only, but call it Download mode.
To come to an end, if everything fails i'd recommend to install stock rom in "download recovery" (Fastboot?) mode via Kies. If this also fails try to put the P605 manually into Download mode (Power and Volume minus or plus), no need to press home button, as often advised. After this, work your way back to Twrp, custom rom and root.

Try connecting the tablet to a Windows 7 PC/laptop, making sure it's on an Administrator account (so it can autoload/download needed stuff). Not Windows 10 or even 8.1, but Windows 7.
I had the same problem a while back ago; if your attempt with this method succeeds then report back; I had an unconfirmed hypothesis about this issue.
Hello, i rooted my Verizon Note 4 with PaulPizzrom everything is running smooth but am having abit of a problem getting into file transfer mode. After awhile a message pops up
"Attention
The connected device is unable to access data on this phone. Reconnect the USB cable and try again. Android File Transfer must be installed on Mac OS X devices. To download Android File Transfer, go to"
I'm using Windows 10 not Mac and don't know what else to do. I've unplugged and replugged on all usb ports and tried different usb cables. Any ideas anyone?
