Hi,
So I just purchased a Samsung Galaxy S II, and I've been trying a few different ROM's found on this site. The last thing I did was actually revert back to a stock Samsung Kernel and firmware. This worked fine, but it unrooted my device, which I knew would happen, but now I'm not able to root it again because when I put the device into download mode, ODIN, or better yet, my computer won't detect the device.
I have all the drivers installed, and I also deleted them all, and Kies, and started from scratch again after searching XDA for similar issues.
I don't believe this to be a driver issue, since I was able to root my device, and swap roms before I went back to the official kernel and firmware. I'm with Bell in Canada, so the versions I went back to were not the official Bell versions, since Samsung has not made them available.
I have a Mac, but I've been using Windows 7 and Odin under VMWare. I can connect my device to either OSX, or Windows 7 when the device is not in download mode, and everything works fine, and Odin detects the device (Not that that does any good of course)
When I connect the device under download mode, the Mac detects the device and asks me if I want to connect it to my Mac, or to Windows (As it should) but no matter which one I select, neither OS acknowledges the device after that point, where as when I'm not in Download mode, both OS's detect the device fine.
After all my troubleshooting with my computer based off of what I found online here, The only conclusion I have left is that there is something missing on the device that allows it to be found under download mode, but that aspect of all this is beyond my current skill level.
Anyone have any ideas?
Are you pressing the Volume Up button to continue in Download mode? Besides, Virtual machine isn't recommended I think.
Yes, Once the Custom ROM warning comes up, I press the Volume up button to continue.
That wasn't even necessary on the Stock Bell ROM. The warning didn't come up at all.
VM has been working fine up until now, so I don't think that's the problem, but I have been thinking of trying this on my old laptop that runs on windows if nothing else pans out.

Have you found anyway to Make Odin recognize to phone in download mode?? Im still struggling with that. my phone is on stock kernel and not rooted yet, ODIN finds it fine when the phone is on and USB Debugging is on, but once I put the phone on download mode it wont recognize it, I dont know why..
Could it be because of the ''SAMSUNG Mobile MTP Device'' driver failed to install correctly??
all other drivers are installed correctly.. I have tried to get the driver mentioned above to install correctly but it fails every time, with USB debugging on and off, i have wiped the phone and installed Kies and the drivers several times, Im clueless right.. anyone have any idea please help??
I myself am also suffering from this problem. However, USB seems to function fine while the phone is booted up or in recovery (For ADB). I'm wondering if necessary files may have become corrupted or deleted in reference to USB drivers (phone side mind you) that are used in download mode.
edit: It's also recognized in recovery mode.
Even if it can't be fixed I'd still like to understand why.

was looking for help on this and saw this thread, same problem too..
Connects to Odin and Kies fine when switched on "normally", can use USB mass storage mode Etc.
comes up with a USB device has malfunctioned message on PC when I connect USB cable when switched on and in download mode
EDIT:- just to add, if I try upgrading firmware via Kies it gets to the point where it switches the phone to download mode to upgrade it and has the same issue even with an official upgrade
Figuring download mode is outside the normal boot procedure, I hoped on an off chance that pulling my battery and sim for a few minutes would reset it. It did indeed. Download mode is now functional again, just to be certain I tested it right before pulling the battery to make sure it was still broken. And multiple flashes and reboots afterwards seem to confirm that it has returned to normal.
Anyone else who solves it with this method, please report back.

Tried this and it didn't work for me :/ going to give it another try later, thanks for the suggestion either way
Samsung Galaxy Gio [Bell] Canada. (locked)
Device: GT-S5660M
Android Version: 2.3.4
Kernel version: [email protected]#1
Baseband: S5660MUGKG3
The device simply wont connect or show up on any PC.
Tried installing KIES (lattest - Kies_2.0.3.11082_152_4). Nothing shows up
Tried putting the phone in downloading mode and then in KIES selected emergency firmware update mode and still no device.
Tried using lattest Samsung USB Drivers (1.3.450.0)
Tried putting the phone in downloading mode and connecting it to ODIN which it does not show up in the COM PORT area.
Tried dialing : *#7284# to change the SERVICE MODE to either USB, UART
Including Toggling DBG MSG
Tried different USB ports.
All doing this with USB DEBUGGING ON and tried with it OFF.
There is no USB Setting in About Phone or in Wireless and Networks settings from the settings menu.
There are many other people with this issue I found but all possible solutions that I have been able to find are listed and attempted but to no avail.
Ive read that others are having no problem connecting to their PC seeing as theres modding / custom rom forums all over. So people are able to connect which leads me to think that this is a carrier specific issue.
THIS IS ONLY MY SPECULATION . NOT 100% SURE
I thought I could start this thread on here to get some more solid advice and help.
I managed to unlock my phone. Not that this matters but I still can't connect it to a pc.
Is there a way to flash my phone with the need of a pc?
Would clockworkmod recovery work?
Would there maybe be an .apk that can be used to install the usb pop up screen or to mount the phone and allow it to be shown on the pc?
Does anyone have any ideas..?
turns out it was actually the usb cable.
I was using a micro usb that came with an LG Eve android phone.
I borrowed my friends HTC Desire micro usb cable and to my surprise it worked!
I hope this helps someone else and stumbles on this thread.
Now before you tell me to reinstall my drivers, I have countless times. I'm 90% sure its an issue with the phone itself. When I connect the phone without debug mode it connects. If I have the phone in debug mode and I connect, the phone does get recognized, but not as a storage device but as a driver installer with a driver installer exe, when ran, it almost instantly disconnects the phone. The phone says connected as an installer, and no matter if I try to install this driver or the actual official driver it will not connect.
I had however connected in S/W upgrade mode and flashed, but it didn't fix the problem. I also tried flashing ICS u-boot and xloader then flashing but I can't for the life of me fix this. The phone is a locked bootloader w/ jb 20h. This problem arose when I flashed JB xloader and u-boot then I flashed the ICS one. I feel as if I permanently ruined a part on the phone, because there are countless other problems that go along with this like crashing etc.
Fixed thanks to Kuma

I originally posted a threat up on reddit, but I couldn't find a fix for it.
I got a Note 2 do Android development on. I for the life of me cannot get the damn phone to connect to any PC I connect it to via USB; the phone charges, just does not connect. The USB icon does not appear on the device when connected either. I tried 3 different Windows machines, with the same warning I get that the device isn't recognized, but reads it as an 'Unrecognized Device'. I have also tried OS X, does not read it as well.
Here is some of the things I've tried from reading around XDA and other forums that haven't worked for me.
Solutions i've tried with no fix:
Various USB 2.0 cables (I do not have the original cable)
USB 2.0/3.0 and other ports repeatedly.
Enabling USB Debugging
Installing Kies, and Samsung driver from their site
Resetting battery
Booting into recovery mode with device connected
Dial codes for some reason do not work on my phone. I tried entering them with the stock dialer to bring the USB settings, but they don't work. I got around it by installing an app to get the USB mode to MTP, still does not work.
Rooting right now is not option, since Odin requires to be mounted to a machine in order to root. So I'm pretty much stuck. Still can't get this phone to sync on anything.
Device info
Model: SCH-I605
Carrier: Verizon
Android version: 4.4.2 (Kit-Kat)
Stock ROM/Non-Rooted
So,
I'm trying to flash my Z5C with latest LP but when I try to enter Flash Mode to do it the phone enters Safe Mode. Now some people say it might be driver related and yes, one of the Z5C drivers I tried installing says this:
Sony Net (03/19/2015 6.0.6000.16511) Not needed (No device for update present)
Now even if it is a driver issue, shouldn't I be able to enter flash mode by simply pressing Vol Down + Power Button? I still enter Safe Mode. Can I not enter Flash Mode any other way than the Vol Down + USB?
I bought this phone a week or so ago and have not fiddled with anything apart from turning USB Debugging and Unknown Sources on. Other than that I have not done anything, not even OTA as it instantly goes to MM. This phone is stock firmware from factory.
Now when I tried connecting to Flashtools by entering Safe Mode (which I thought was flash mode but with a diff name) Flashtools either says Debugging is off or it goes as far as saying "Root Access Denied" (Note: it's not an error, just another message) and stops. The popup which says to plug in the phone doesn't dissapear either. So that's where I'm stuck and it's due to me not being able to enter Flash Mode on the phone.
So question is, what am I doing wrong?
PS. I will try this all over again on my W7 desktop as I've only tried with my W10 laptop and I know there are different driver settings. Yes I did enable "No Driver Signature"-mode on W10 prior to installing them but nothing changes.
Thankful for any help as I don't want stock, cause it's not very optimized and also phone can get a bit hot whereas they fix a lot of issues with these updates.
[EDIT]
Btw, can't find Sony PC Companion on the official site. Instead it's replaced by Xperia Companion. Inferior in tools but I assume they have the same drivers for phones included?

USB is the only way. I had to use 4 different PCs before finding one flash tool liked BTW. And you are kind of wrong about they fix issues with these updates. They really just create more. I'm on.200 LP and probably never going MM until aosp can deliver because MM is so messed up.
Did you get this sorted?
I can't boot into flash mode either, and I am stuck on a boot loop. Phone trying to setup and processes stopping.

Thank you for the suggestion to try different PCs. I only have the one at home but I tried a different USB port and Flashtool is working now. Bizarre.
