Hi,
About two weeks ago I updated my Samsung Galaxy S II to the latest nightly build of Cyanogenmod (through the updates part of the phone). Unfortunately I do not remember the build number of the nightly I updated to - but it must have been near 2014/04/07 (7th april 2014). It made quite a few things not work (It still worked as a phone), so I decided to downgrade to the latest stable build. (Again usint the updater built into the phone)
Now when I turn on my phone, the Samsung Galaxy S II screen comes up. Then it changes to the Cyanogenmod rotating circles boot animation, and stays on that boot animation.
I cannot access recovery mode.
I could not access download mode - but I got a jig and now I can. However when i connect my device in download mode to odin 3 v1.83 to flash it to stock the following error message appears: "USB Device Not Recognised. One of the USB devices attached to the computer has malfunctioned, and Windows dows not recognise it. For assistance in solving this problem, click this message."
I installed the samsung drivers from kies, then uninstalled kies but not the drivers. I disabled my antivirus.I do NOT have the android SDK installed.
Does anyone have any advice on how I can fix my phone?
Summary:
I rooted the device and installed cm 10.1 a while ago - my custom recovery was CWM
I got a notification that a nightly update was available
I updated to the nightly using the updater built into the phone. That was my only update since i installed cm 10.1. (Nightly was from about 7th April 2014 - not exacty sure)
It worked fine as a phone, but some functions didnt work.
I went back into the built-in updater and chose to DOWNgrade to the latest stable version.
When I turn on the phone now the Samsung Galaxy S II screens appears.Then the cm rotating boot animation appears.
The cm boot animation doesnt stop and the phone doesnt turn on
If I try to enter recovery or download mode using the buttons, it goes to the Galaxy S II screen then the cyanogen boot screen - same as if I wasnt pressing buttons
I bought a Jig which I can use to access download mode.
I have the drivers installed on my computer however I still get an error when trying to connect my phone in download mode to ODIN, which prevents me from flashing stock or recovery.
My other phone works fine when connecting to odin on the same computer
Any help in fixing this is appreciated. cheers
Your only option in this situation is Hopper 8's 'Odin troubleshooting' thread stickied in General. Try everything in that thread as many times as you need to in order to get a successful flash.
One thing stands out in what you've said though...
The errors about USB malfunctions/etc may also mean the USB board/port on the phone is on the way out. If you spend a few days trying the stuff in Hopper's thread & still can't get a successful flash (BTW, this is the only way you're fixing it, there isn't anything not in that thread which can be suggested in these situations), I'd replace the USB board/port. KeithRoss39 has a guide in General (not stickied; search for 'replace USB charger board' or do an advanced search on his username) which will enable you to do this yourself quickly/easily/cheaply (<US$15). The boards don't normally die completely, and often only exhibit a few faults while otherwise working OK. What you've described (not being able to get a successful flash, connection errors/problems) may well be the board malfunctioning.

There's also a link to Keith's guide in my troubleshooting thread
Thanks for the advice. I'll try out the odin troubleshooting thread and replace my micro USB connector part if that doesn't work.
I'd be tempted to do things the other way around......if your port IS faulty, and it fails during an Odin flash, it is likely to kill your phone permanently. As @MistahBungle says, the part is cheap and easy to fit.....certainly cheaper than a new motherboard which will be your only alternative if the port fails during the flash

Disclaimer:
I've searched all over the forum and found few close to my problem but this seems different
Background:
I recently flashed my Galaxy S2 International version with CM9 nightly build. Since then, when I turn off the phone and put it for charging, the battery charging animation stays like that till the phone is fully charged unlike the stock ROM where that animation disappears after some time.
Simultaneously I've noticed something else, when my phone is plugged to USB cable attached to my computer, a pop up appears at the bottom right (notification area) which says "USB Device not recognized" and in Device Manager it's listed as "Unknown Device"
I ignored it thinking that it might be an issue with the CM9 Build as it's not fully functional. I've had the phone that way for around 10 days.
Recently I thought of switching to XXLPQ(Official ICS Update) and I got into Download Mode but Odin doesn't see the phone. No "communication" establishing between phone and computer.
I also had CM7.1 on SD Card and I thought flashing that old CM might bring my USB functionality back.
So got into ClockWork Mod Recovery and flashed it. Flash was successful. But now phone is in boot loop with "Samsung Galaxy S2" with an exclamation.
If I try to press and hold the power button, it comes back to that battery charging screen even though phone is not plugged to either USB or charger.
I can get into download mode(Odin can't see the phone) but not into Recovery Mode.
Three things that I see as of now on my phone are the boot loop I mentioned above or Download Mode (but not recognized by Odin) or Battery Charging animation.
I'm sure there's nothing wrong with USB Cables or Drivers or Kies or anything else. Because my brother's S2 works just fine which is on "Stock ROM".
I need help. I'm sure that CM9 nightly broke that basic USB Device functions on the phone.
Please let me know if there is any alternative for recovering my S2. I know that the worst is, it goes to Repair Center.
But I hate to give up on this!!
Are there any other tools or recovery softwares which can be used to re-flash the phone other than Odin no matter what screwed up state the phone is in!?
Deleted - sorry, hadn't read your post properly.
firstly i want to ask does your phone charges? if it does it sounds like u dont have development option enabled.. or ur usb port is broken.. if it doesnt charges then im pretty sure ur usb port is broken...
about the recovery.. can u use ur SD card on ur brother's SG2 and put stock rom into it? and then insert it into ur SG2 and try flashing it throught CWM

Thanks for the response Warrez!
- Phone charges (but that battery charging logo stays like that)
- When I flashed CM9 nightly I'm sure I haven't checked or played with Development option (It's not enabled)
- And last, I'm not able to get into Recovery Mode as well (already mentioned above)
Any other inputs!?
I have the EXACT same problem
Me too exact same problem .
I've confirmed my setup is fine as it works with Odin for my tab 7.7
Exact same issue, stuck at Samsung logo with exclamation mark. Can't get into recovery, can get into download but computer says device not recognised .
I was running Slim ics at the time then about to switch to cm9 and siyah kernel

Well.. I made some progress in last few days! I've taken out the battery and got into Download Mode. I was holding buttons and my brother inserted the battery. What I did was I powered of the system and connected the phone while it was in "Download Mode". I waited for some time.. Say more than 3-4 mins.
Rebooted my PC and once it's back it wasn't saying anything. For my surprise I see the "Yellow COM" established in Modem. Without delay I grabbed recovery ROM which is posted in one of the sticky threads. Flashed the phone.
Now, it got little interesting! When the phone is booted back post flashing it shows that "MTP Device" even though USB Cable isn't plugged into it!
When I turn off the phone, it either reboots back without hesitation or ends up at "big green battery charging" animation!
To get back into OS, I have to get into recovery mode and then I use "Reboot System"!
And that "USB Device malfunctioned or not recognized" thing is intermittent.
At times it says that and at times it establishes "COM connection" in Odin.
I re-flashed old bootloader thinking that it might be a phone's basic operating driver issue. But that didn't solve the issue!
I've even flashed latest stock European ICS Firmware.
And with ICS, things got even more interesting!
It started throwing up new message "Charging Paused due to over voltage"
What I'm sure of is.. It's definitely got to do with CM9 ICS. Because when I was on beta official ICS before I switched to CM9 Nightly phone was working like a charm! As soon as I flashed CM9 Nightly, I started getting that "USB Device Not recognized" issue with the battery irregularities.
I wasn't sure how I could get the phone recognized in Odin. Hastily I flashed CM7.1 on CM9 compatible ClockWorkMod Recovery enabled Kernel. That is when the problem got more complicated!!
I'm about to give up and pay someone to fix it via Jtag.
I've tried several computers, several cables , multiple reboots and everything else.
Windows just still says usb device not recognized so the phone must be corrupted somewhere.
Please change ur USB cable, i had this problem n its only frm the cable.
I don't believe this.........
I had tried two other cables ( a nokia usb>micro usb and another one ) as i had lost my samsung usb>micro usb lead and both those said unrecognised device....
I had just given up, ordered a jtag repair and then my old dear finds the samsung cable!!!!
Bizarely it now recognises the phone.
Hi Guys
I am having the exact same problem and am still looking for a solution.
My phone is not recognised by the PC after installing CM9 Nightly and now I am stuck until I can get the device driver installed again so that I can use Odin.
I am using the official Samsung USB cable which worked fine until the CM9 flash.
I am assuming this is a common problem so am hoping that somebody can supply a fix asap.
Any help will be appreciated

I had the almost the same problem .. I took it to the place I bought from .. and fix it .. they told me it was a hardware problem ( I remember with the hard disk .. I forgot )
The same thing, after using the Custom ICS LPQ roms!!
Now there's no way i can't use Odin to flash official rom!

Last time I checked.. My phone is getting detected in Odin. But not always! Every 5 attempts it sure is seen by Odin 2-3 times. And it's on ICS 4.0.3 XXLPQ with "Charging Paused high voltage detected" message even though it's not plugged to charger or USB Cable.
My brother advised me to leave the phone that way and wait till it goes dead and then keep it dead for at least a week and then try charging it fresh with phone's stock charger. Now 5 days passed and I'm waiting for another 2 days to try this out!
Cheers,
A.

Gee.. Try this! Take the battery out of the phone and press the power button for few secs with the battery out. Take someones help to put the battery back while you are holding the download mode button combination.
When you get into download mode, leave the phone that way and do not plug it to the USB Cable. Power off the PC and wait of 3 mins. Now connect the phone to the USB Cable while the PC is still off and phone is in Download mode.
Turn the PC on and wait for till it reaches desktop and then give it 3-4 mins. Now launch Odin. If you have any luck you should see that "yellow COM"!
The same procedure worked for me! If you happen to see that "yellow COM" on Odin don't delay anymore. Just flash any stock ROM. 2.3.6 or 4.0.3!
P.S.
Odin may not see the phone on the first attempt. If so.. Repeat the steps for 2-3 times
All the best!
Cheers,
A.

This is what happened. I want to upgrade my Samsung Galaxy tab 10.1n from 3.2 into 4.0 . I try to root and somehow I do some stupid error.
The bootloader screen become rolling. I found the solution from this thread http://forum.xda-developers.com/showthread.php?t=1555984 and it runs perfectly. my bootloader become normal.
But another problem come out after that. my PC can't detect my samsung through USB. any guide for this problem??
Change usb port or cable
Dont use usb hub
Reinstall kies 2
And retry

noob here.
Galaxy Tab 10.1 P7510 Wifi
I have a similar problem to the above.
When I connect using the usb lead to the pc, nothing happens. I have reinstalled the drivers (both with and without Kies 2) and upon connecting the usb it acknowledges a connection and goes through some steps and proclaims the device is installed and ready to use. Except it's not. It doesn't show up in My Computer or when I remove and re-connect the usb, there is nothing - the same as before I resinstalled the drivers. Kies cannot find it either.
My issue is further matched by the above issue as I also followed the same guide as above. I previously tried to root the device several times and each time the recovery screen was doing the rolling / flicker thing. So I returned to stock. But inevitably I would get infuriated by all the things I couldn't do.
So when I found the guide http://forum.xda-developers.com/showthread.php?t=1555984 that further linked to http://forum.xda-developers.com/showpost.php?p=27830023&postcount=41 I was thrilled because I could finally read the Recovery screen.
So I proceeded to root the device as per http://forum.xda-developers.com/showthread.php?t=1474971. This was working fine with one exception. Which was that after the screen went into sleep mode and I pressed the power button to wake it up, the tablet was in a variant of the rolling / flicker screen. This happened every time. I repeated the rooting process making sure to wipe data / cache / dalvik.But it remained.
So I became adventurous and decided to flash an experimental CM9 sourced from droidbasement.
And that is where I am now. Unable to enter sleep mode and unable to connect to the pc to return to stock or try different roms.
Any suggestions or help welcome.
perhaps I should have opened a new thread but wasn't sure. please advise if so.
I used a different usb port and the pc could find it.
Now back on stock.

Hi guys, I need some help with my Samsung Galaxy S3 GT-I9300.
A couple weeks ago my phone turned off by itself and never turned on completely again. If I turn it on, it stays on the very first boot screen forever (the white text saying Samsung Galaxy S3 GT-I9300, like this one (https://cdn-images.xda-developers.com/direct/1/1/5/2/1/9/8/I9300.bootlogo.jpg).
I've removed the SIM card and the MicroSD card with no effects whatsoever, and I've also left the device turned on for hours but it always stays on the same screen.
I cannot enter recovery mode (it just shows the boot screen mentioned above) but I can enter download mode. At download mode, I get this info:
ODIN MODE
Product name: GT-I9300
Custom binary download: No
Current binary: Samsung Official
System Status: Oficial
As you can see, I have never flashed a custom rom (or rooted or even unlocked the bootloader). This is what intrigues me the most, since everybody I've seen with the same problem had trouble during or after a flash.
My last OS version was 4.3.1 and it was received OTA months ago.
In the past few months, my device rebooted out of nowhere, even when I was not using it. Occasionally, it had the stuck power button, which caused it to reboot on a loop, but I always solved it by nudging the power button a little. I don't know if these two previous problems might have caused the problem I'm facing now, but they're not showing up anymore.
Anyway, I've tried to flash the newest official rom (NK1 - ZTO) via Odin but I always get a NAND Write error.
I've tried changing USB ports, USB cable and computers; tried Odin 3.04, 3.07 and 3.09; tried Samsung USB drivers v1.5.45 and 1.5.49 but nothing of the above made any difference.
Today things started getting worse, though. In the past, Windows would always recognize the device on at least one specific USB port; Odin would also recognize the device and then I would get the NAND Write error. Now, Windows will not recognize the device no matter the cable, USB port or driver version. I only get a unknown device error and Odin won't recognize anything connected.
I tested all my setup with a working Galaxy S3 I9300 and it got recognized every single time, no matter the USB port, the cable or the computer.
Considering that another device is getting recognized by different computers, I suppose that the problem lies in my Galaxy S3.
So, can anyone offer me any kind of advice or point me in any direction on how I can try to fix my phone? Is my phone physically dying and no software solution will unbrick it?
Your power button issue has corrupted/damaged the nand memory. Try the dead boot recovery thread in general forum but unless you have warranty you might be better off with a new phone.
I was afraid of that.
I checked the post you mentioned but it seems I'd have to buy tools and hardware more expensive than the phone itself, so I'd rather buy a new smartphone.
Thanks for the help!
Hello everyone, I could not find a good title for my issue but I will try to explain as well as I can. I own a GT-I9300 (International), but since last official Samsung's firmware update(Jelly Bean 4.3) I am not able to get my phone recognized by my computer. Phone is connected and it charges, but neither Windows or Ubuntu recognizes it as a portable device. I am concerned about UMS is not available on device, but my phone it does not even get detected! I also own a Galaxy SII (4.1.2) and it does get detected by my PC. I think that flashing a custom ROM could solve the problem, since it appeared when I updated official firmware, but the thing is that I cannot root my phone! Tried ODIN but since my phone does not get detected, ODIN does not do its job. I also tried rooting with framaroot and towelroot, but no success: first one says "Failed , try another exploit" but there is only one. And the last one says my phone is not currently supported, even if I change modstrings.
So here is my question: how do I root my phone? I don't know what else I could try. I have already reinstalled Kies and Samsung USB drivers but still not working. Also hard-resetted but no luck.
Hope you guys can help me out because this is really getting on my nerves
Thanks in advance!

Try with other port and USB cable.
Have you Degugging Android activated in Deceloppers options ?
the other day i tried for hours to get my phone recognised. what did it in the end was trying it on a different pc and it worked

The thing is that my phone is the only one that do not get detected every single time I connect it. I have already connected one GT-I9100 and GT-S6790L and both get detected. I already tried on 3 different Virtual Machines with Windows XP, Ubuntu, Windows 8.1 but no luck.
As I said in the first post, I think it's a firmware problem since it appeared when I did the official update, which was this one:
Model GT-I9300
Model name GALAXY S III
Country Argentina
Version Android 4.3
Build date Wed, 05 Nov 2014 20:33:08 +0000

I can see your frustration Now a few things technically it is a misconception that you need root to flash a custom rom you can actually flash a custom recovery with Odin full wipe and then flash a custom rom from custom recovery (only thing is you will lose all your data because you need root to back up your data)
Now I know the above statement is not very helpful because as you said Odin doesn't detect it (but I thought I would mention it anyway )
The reason framaroot and towelroot, didn't work is because at the moment the only way to root S3 is with Odin.:crying:
You may have tried this but I will mention it anyway first uninstal Kies and all Samsung drivers from your computer ( kies can interfere with Odin) Then try installing these drivers here >> http://developer.samsung.com/techni...Lhp1GqlWRy92Q60CX6PP1mF!80806326?v=T000000117 << If you have tried this then sorry.
Also when you connect the phone go to Device manager in Windows and try to look for your device ( it may say unkown device) it should have a warning triangle right click on it select update driver software and then select browse from my computer and point to the drivers that you have downloaded see if that works.
Another thing to note is if you are using Windows 8 you need to disable Driver signature in start up options ( Google it) for Windows to recognize the drivers.

I already tried uninstalling Kies and Samsung drivers. Also I tried looking for device on Device Manager but it does not appear when I plugin my S3, but it does appear when I connect other devices like S2 or Galaxy Fame Lite. They appear as portable devices.
I'm using Windows 7 on my PC and have already tried with different OS over Virtual Machines and still doesn't work.
And thanks for that note, didn't know there was possible to flash a Custom Recovery without root, but I can't since ODIN doesn't detect device :crying:
Then it looks like you are running out of options I would use another computer not Virtual Machines
Okay I'll give it a try but as I said before, looks like an firmware issue, not computer's. Why would my computer detects two another Samsung devices but not mine (which used to work until last update)
Me, too!
I'm having a similar problem. Last week my GS3 stopped working, and I bought another one from Ebay with a cracked screen and swapped out motherboards. The phone seems to work as well as a stock Verizon phone on Jellybean would, but I can't get my Linux, Win 8, or Win XP computers to even recognize that it's attached. Different cables, each and every one of the USB ports, not even a blip. Device Manager in Windows doesn't even see it, and yes I got the developer options unlocked and have enabled USB debugging.
I've got the Samsung drivers installed, and tried to install the CWM device drivers from the SAMSUNG GALAXY S3 TOOLKIT V9, but there was an error and that didn't work, either.
USB connection issues are usually due to Windows conflicts, driver problems or the lead itself. If all these have been excluded then you have either a firmware issue in the bootloader, which is very uncommon, or a hardware problem. The usb port is easily worn/damaged/dirty also the motherboard might be the cause.
There is no silver bullet to cure, test each possible thoroughly.

I'm 100 percent sure that it is not due a Windows issue, I have already test every option. I have not considered the usb port to be damaged or worn, which could be possible but phone charges every time I connect it to computer. It just does not get detected as a device. But in order to assume it is a motherboard issue I will have to put away my feeling that the problem is caused by last OTA official update, since this problem started there.
If it is a firmware update issue, is it any option to flash another ROM?

As I said on previous posts, I have already installed and reinstalled Samsung USB drivers and made a factory reset -one from config. option and another one from Android stock recovery 3e (since I cannot install any advanced recovery -or even root it- to flash a custom rom). Doing those factory reset did not downgrade my last firmware update (when all my problems started).
I also said on previous posts that I tried towelroot and framaroot with no success. As tallman43 says, seems like international version of S3 does not support those kind of one-click to root apps.
-----------------------------------------------------
So far the only options available (if my theory about latest firmware update is the problematic one) are:
● downgrade firmware: [Q] How? Odin is not working since my phone does not get detected;
● root my phone in order to install an advanced recovery and flash a new ROM: [Q] Any way of rooting phone without computer (apart from towelroot or framaroot because I have tried and do not work for me)? I read one XDA post from 2 years ago to root S3 via console apk but latest comments assumes that method stopped working.
● install an advanced recovery without odin or root: [Q] How?
● fix USB firmware issue: [Q] I have completely no idea how to do it. (Already played with *#7284# and *#0808# but did not get my phone detected)
Please I need help, this is really irritating me and I am running out of ideas

I guess I have found out what the problem was. It was not firmware (as I thought). It was the micro USB port (as boomboomer said) which seems to not be firmly attached to the PCB. AC charging just seems to work okay, but not USB connections. I managed to figure it out by forcing the USB in a specific position to get it detected for 5 seconds, but then it disappeared.
Yeah, it was not as complex as I thought! I will try to replace that micro USB port as soon as possible, thanks everyone for your help!
Hello, I am sorry if this post has already been made somewhere but I still can't find the answer for fixing the problem suggested in the title.
So I have a GT-S5830 Galaxy Ace and decided to install CyanogenMod 7 with CWM. The flashing of the phone was a success but I came across a bug (or problem?) of screen orienteering and I couldn't find that answer. Right after this, I then decide to restore back to stock ROM. However, I came across a problem when connecting the device (in Download Mode) to my PC; it stated Unknown USB Device (Device Failed Enumeration) in Device Manager.
Following Procedures I have done:
- USB Debugging enabled on phone
- Samsung USB Driver installed
- All drivers on PC up-to-date
I am also following a guide to restore back to ROM using Odin Multi Downloader, but it does not recognize the phone in ID:COM. The bleep on the PC can be heard but it only recognizes when the phone is in normal mode; in Download Mode it shows Unknown USB Device (Device Failed Enumeration). Please help as I am giving this phone to my sibling.
Thank you. (I think I may have posted this on the wrong section of the forum, sorry)

I'm having the same error as well. I am running on stock firmware 2.2.1 and unrooted still when I enter Download mode (Power-VolDown-Home) my PC says USB not recognized. I'm trying to play some combinations and I've been into RAMDUMP, Emergency DLOAD mode and ODIN can detect it, but can't flash. When I press Power-VolUp-VolDown it Says LK (lucky kernel) version Jan 2011.
Tried updating via Kies but it says Can't update firmware. Unknown error occured. This is crap! I can't go on to 2.3.6
I have exactly the same issue. :crying:
Does anybody has a solution for this?
