[Q] Windows shows 'unknown device' in Download mode..

This is probably getting boring to some people now but i am having a major issue with Odin detecting my phone when it is in Download mode.
Once i connect the phone after loading up Odin and holding the 3 button combo, Windows installs 2 more drivers - USB Device and then Unknown Device. Then nothing, Odin just sits there and no yellow box glows or a COM port showing the phone is connected. I have tried installing Kies originally and using the drivers from that with no success, then i used the standalone driver packages available from softpedia and several other websites with no luck. What i can't understand is, when i connect the phone to my computer in it's normal state it has no problems and allows me to transfer files, access both the internal and external SD but shows as an 'unknown device' in the Device Manager when in Download mode... Why??!!
Somebody please help me!

Which rom are you using?
Also did you try this on some other PC/Laptop?

I have not tried it on a different computer yet, not sure if i need to considering it connects normally when the phone is on, just not in Download mode... I really don't know what's going on!!

Stock rom shouldn't have this problem.. you should either uninstall everything related to samsung from your computer and then start again or try connecting to a different PC.. you'll be able to find out whether this problem is just with the single system or not

I always run up Odin, then use the 3 buttons to get to download mode and then connect to USB port.
Sent from my GT-I9000 using XDA

I had the same problem, then I finally got it to work.
Try this:
First off, you may need to try several different versions of Odin. The one I finally got to work on my phone was V1.85. you can find a collection of different versions to download here: http://droidangel.blogspot.com/2011/05/odin-multi-downloader-flasher-program.html
Next, Load up Odin. Plug in you phone to the USB port with phone powered on, remove the battery on the phone. While holding the 3 buttons down (Volume up, down & power) put the battery back in. Wait for the text to start to scroll, let go of the buttons. When it gets to the menu, unplug the USB, then plug back in. The yellow box in Odin should say it's connected. If not you may have to do this a couple of times.
Now this is the part I can't remember...I think what I did from here is chose the recovery option in the menu. Sorry I don't remember exactly what i did, I was a noob when I did it, and I think I got lucky.
I do remember that Odin would not flash it until I finally got to the screen with the picture of the android in the construction hat, or something like that.
Maybe someone with more experience can help with this part.

I had the same problem

The fix is: Use the USB JIG to get into download mode.

Update your PC USB driver for SGS1. Follow the OP on this link:

Cannot access download or recovery mode after failed flash

Hi,
I attempted to re-lock and then flash my i9305 yesterday with the latest firmware,
However, I must have done something wrong, but the Odinupdate failed and I now cannot enter Download or Recovery modes from a powered down state.
Instead, I am presented with Firmware upgrade encountered an issue. When I try to power up the device, all I see is this message "Please select recovery mode in Kies and try again."
Even though the handset doesn't boot up properly, Windows seems to detect it and the driver support kicks in but Kies and, ABD and the GS3 toolkit will not recognise the existence of the handset.
Is this now dead and irrecoverable or can I fix this?
I have checked out the usual links on here to see if I can get the handset to startup in recovery mode again.

Looks like I'll need to try a jig. I can't lose too much as they only cost 99p on ebay

Hi,
the USB Jig won't enter Download Mode if you can't do it with Vol Down + Home + Power

[Q] Optimus 4X HD full brick

I tried to put the CM10 on my phone, after installing the zip in recovery mode, I rebooted the device and it never returned to start. Does not show a single light. Do not enter in any way with any combination. When I connect by usb the only thing that appears in device manager is "apx device." Already tried so many things and nothing worked.
anyone have any idea what's going on?
by the way, I tried a lot here in xda before opening a thread.

is your bl unlocked?

No, no, no and no. the only sign of life when it is connected to the pc. Appears "apx" in device manager.

Yeah you are in apx mode, which is basically the boot section of the nvidia tegra chipset.
You should be able to boot normally by unplugging the phone, remove battery for a few seconds, reinsert and hold power button for about 10 seconds
Also try holding power and vol+ (hold them a while) you should be able to boot into normal recovery

I've try that but dont work.

In device manager the apx device is it properly installed or does it have the triangle?
When it first connected as apx device it probably asked you for drivers, i doubt you installed them.
I don't know if the apx drivers for the 04 are out already, check these terms in xda i know some people have been working on them.
Maybe you can find them here
If the device isn't bricked you are in a situation in which you should be able to flash stuff.
For some this method worked:
Try turn off phone
take battery out
hold vol- and put usb cable into phone
if s/w mode starts put battery in and flash kdz
Otherwise check this thread out
or this
I have to go out and can't follow you for a while, sorry

The only way for you to get connected in APX is without battery, connect to PC while pressing vol- & vol+.
Anyway... why you want to do that? APX mode doesn't work in JB.
Ok... I got it.
Did you tried to deactivate the APX device in device manager?
You can try to performe the bootloader unlock again (run adb and connect the phone while the program wait for device...)
http://www.4shared.com/rar/HFf4newq/LGO4X-UNLOCK-BOOTLOADER.html (instructions inside).
Or try to get in SW mode by trying untill it works... (connect to PC while pressed vol-).

Any update on the problem?

No, i think what happened was that all the firmware is erased and this naturally gave access to apx that should be hidden by the software. Probably there was some error when I wipe to put the CM10. I see no other explanation.

The phone is actually mine. Already sent it to warranty hoping they'll fix it.
Resuming, the phone went unexpectadly in APX mode and havent found a way of quitting that mode, couldn't boot S/W neither bootloader.
And btw the phone is carrier locked and to be honest I'm not sure if it might be part of the problem or not. Anyway in about two weeks the phone should be back and hopefully fixed. If not I'll check here for some more help guys, thanks for attetion so far

When you say Odin doesn't see the phone, I presume you had put the phone into download mode?

the phone doesnt register in odin or with my computer. i need to know how to make my computer see the phone so i can use odin to fix it.

For the second time, did you put the phone into download mode? Odin isn't going to "see" it if it isn't in download mode.

I go into download mode and odin doesn't see. my computer doesn't recognize the phone at all. I want to know how to get computer to recognize that phone is connected so I can run odin or hard push file to phone.

Like @cwhiatt is saying, are you certain you're in download mode - by pressing and holding volume down + home + power? If you're in TWRP, that's recovery mode, not download. Just want to make sure that's not the issue here.
In download mode there should be a blue/green screen that says "Downloading... Do not turn off target".

Have you tried other cables? Other ports? Other computers?

some usb cables are for power only while others do data if it has just a lightning bolt on it, that's a charger if it has the universal usb logo that's data cable.

Your problem is fixed ?

I can get to it via recovery on my Note 9,I have no explanation as to why you're having issues.
Perhaps try the method given in post #2 of this thread.

New method now for Note 9 download mode. Power off, hold Bixby+Vol Down and connect USB cable to PC to trigger it.

Can't boot into download mode too....
Australia ver....

Yip, this works...but tricky combo to hold down Bixby and Vol Down while plugging into USB power...I almost took my device in for fixing because I just could't for the life of me boot into Download mode after encountering the dreaded custom binary error on trying to boot up...
