[Q] Cant get into download mode or get any computer to recognize my Galaxy s2 t989

i cant get into download mode at all. im on the tmobile version t989 and i tried everything. i did the official update to ics thru odin and now i wanted a pure android rom but i cant get into download mode. i think the problem is that i can only get into download mode when im connected to the computer but my computer or any computer for that matter wont recognize my gs2. i ordered a usb jig but was also thinking of replacing the usb port of the phone. i really have no idea what to do and was hoping someone here would beable to help me. btw when i plug it in to the computer all it does is charge and i can still boot into recovery but its android stock recovery. and i have tried to reinstall kies and have kies reinstall the drivers and go into the kies folder and run the exe file in USB drivers folder. nnothing seems to work. i dont know if it has anything to do with not having Samsung Mobile USB CDC Composite device in device manager.
any advice would be greatly appreciated
thanx

Let's just make sure you're following the right steps. Remove the battery for ten seconds, insert the battery, press and hold volume up + volume down and then plug the usb cable that is already connected to your computer. Continue holding the volume keys until the phone turns on into download mode. You press volume up to continue once download mode is down on the screen.
The power button is not used when booting into download mode.
Make sure you have Odin open before you connect the phone and you should see your phone connected. Then you can flash the stock ics for Odin found in development.

Post your general location.
Maybe a local can hook it up to their computer and give it a try.

tried it
i did that like other people have said to do but as soon as i plug in the usb it goes straight to the battery charging image. i have odin open i turned off and let the battery ist for 10seconds then i hold both vol up and down and plug in the usb and as soon as it plugs in it goes to the battey no samsung no tmobile logo just a charging battery.
what else can i try

Did you try another USB cord? I know it sounds funny but the cord from my g2x will not allow me to connect to PC with my gs2...just saying it might help...or try to reinstall the drivers
Sent from my SGH-T989 using xda premium

lol you upgraded from a g2x too.
yeah i have like 4 different cords and none of them work now but to get the updated 4.0.3 i had to use the cord it came with and that along with the other cords i have only charge now. i dont think its a problem with the cord that im using but thnx

forgot to mension a usb jig
i bought a usb jig its comming in the mail. would i beable to use that to get into download mode and get back to 2.3 when things were working?

Had the same problem with the wifes gs2. No matter what i tried, the phone would not be recognized when connected to a pc. It is a known hardware problem affecting some phones. I called up tmobile on saturday and they offered to overnight a new replacement. I suggest you try giving them a call.

i'll try tmobile
only thing is that i dont hav a warranty because i bought it from ebay but i will try thanx

Have you tried blowing a can of air in the usb port? Sometimes dirt or debit gets in there and causes it not to get a good connection.

but it charges fine would dust cause it to loose connection to the computer and still let it charge?

Might also try removing battery, hold volume keys, hook up to computer, then reinsert battery.
Edit: Have you tried different ports on the pc? Mine, won't connect on one port.

Scrub it with a tooth brush. Bought mine from Craigslist and it would charge but computer would not recognize USB connection. That did the trick for me

Might be helpfull
Maybe i can help,
I know you're on t-mobile but maybe button combination changed or might be helpfull info....
I have the telus version of the SGS2 the ''X'' version..
I tried every possible ways to get access to the download mode but here is the problem i found.. the button combination to get access to the download mode is different from the t-mobile version.
On Telus version if you hold both volume up and volume down while holding the power button nothing will happen and it will only get in bootloop.
If you want to get access to the CWM recovery ( if installed ) or the original installation you have to hold both volume up and volume down but when you press the power button you have to release it when the phone vibrates and keep pressing the 2 volume buttons.
If you want to get access to download mode : you need to keep pressing only volume down and power button.. it will get you download mode after something like 3 seconds. Then it will show you a warning screen and ask you to press volume up to continue or volume down to cancel and restart the phone..
I taught it might help you or others with similar problems

I guess what i realy want is to beable to flash a different rom
is there any other way to flash a custom rom without using download mode. i would like to beable to connect to my computer but the whole point is to get a different rom because i dont like samsungs ICS. i want a pure android 4.0 rom with working camera. can any body please help me

i have tried that

This was one of the methods i tried to get into download mode but i think that it goes into download mode when odin is open and the usb is plugged in. this is where i think im having the problem because when i connect to the computer all im getting is a charge no matter what usb i use or what computer i go to. if my computer wont recognize it then odin wont know that its connected and i cant flash any custom rom if i cant use odin.
i was hoping that there was another way to flash custom roms without having to use odin or download mode.
is there any way to do that.

also i can get into download mode using the jig but it doesnt realy help anything if odin still doesnt recognize it

THANK YOU

You have to use volume up and down at the same time. So press both volume buttons and power button at the same time to get into the bootloader.

I understand that but my volume up button does not work. stopped working randomly about two weeks ago. Therefore I can not get into bootloader. Only odin mode. So once in odin I cant get odin to see the gnex. I imagine its the drivers but they seem to be installing ok. Anybody have any ideas or am i screwed? I also took it apart to see if i could see something wrong with volume up button. No luck

Do you have USB Debugging enabled in your settings? If so, boot your device (yes, I understand that you will only see a black screen, but it doesn't matter) and plug into your PC. Once it is fully booted, open a command prompt on your PC and type: adb reboot bootloader
Then you can get into your recovery and then follow the instructions here.

It was enabled before the issue. Thanks for the advise but t gave up trying to fix it. Its my company line so I just ported my number to a temp phone and awaiting a replacement from assurion. Cant afford it being out of service too long. Guess i will just start over. But this time no hardware issues so bootloader wont be a problem again.

well **** me....
I just wanted to reboot my DHD and now i have thi outcome
Vibrates 3 times flashes orange lede no reaction anyhow

Pull out your battery for 2 minutes, put it back and try to boot. If that doesn't work then:
1) Power off your device (pulling out battery is the bulletproof way)
2) Press the volume-down button and hold it, then press the power button until you see a
white menu screen (bootloader)
3) Try to access recovery (navigate with volume-keys and powerbutton). If you cannot
access recovery then:
4) Download this file http://www.multiupload.com/BTJ8KY0KH9 and put it on your SD-card
root with an external memory card reader.
5) Boot to bootloader again and accept the installation
6) See if it works.

like to do all of this but it dont boot into bootloader doesnt mater if i push volume up or down and power on either way it vibrates 3 times than flashes led.
still... is HTC able to detect a rooted device even if it dont boot? and if so can they deny the waranty

This has happened to me 2-3 times. I definitely think it was because the battery didn't have enough charge. Try charging it for a little time. Have patience.
If its not getting charged I think there might be some problem with your charger, charging cable, charging port or battery.

wll the battery was charged 100% just before that happened - and i tried another battery after this happend - because i was about to install a new rom. so it checks aut that when i try to hboot that its vibrates 7 times than flashes green led (when vol down + power) when i start normaly or when i try to vol up + power its vibrates 3 times
and flashes a orange led ( normaly it would be red but i was on blackice mod)
i have varanty left on that thing and it was rooted s-off when i send it in are they able to see this?
and could they deny varannty?
it was only slightly oc´ed to 1.3 instead of 1 ghz thera was chainfire installed too
Windows 7 trys to recognice the device when i plug it in per usb but cant find the right driver.
thanks for the ideas

That's strange. When that happened to me it was fine when I charged up the battery.
Unfortunately, considering the fact that you can't even get into bootloader and that windows cant recognize your device I'd say you are pretty much bricked.
Do you get the splashscreen atleast? the one with the white HTC logo?
Are your volume keys working fine? I mean were they working fine before this happened?
Well I'm pretty sure that if they can't get to the bootloader, they have no way of knowing it was S-OFF. So they can't deny warranty in that case.
On the other hand, if the issue that caused this problem was indeed an issue that could've come only after someone S-OFF's then they might just deny it.
But I'm pretty sure you can fool them by maintaining that you don't know anything about how it happened.

Nope. Wont work. The computer has to recognize it atleast. In anycase, adb works only after the mobile boots past the splashscreen. And I think he might have already be knowing about adb since he's flashing ROM's.

thats the point ther is no splash screen at all. i think this is a great myth the comunity cant solve by now. i read this a bunch of times many post to the 3 vibrations on boot or 7 vibrations ther is suggested that the mainboard passed out but what coused this if so?
otherwise i saw post on peaople were able to fix this bug and therfore could be no mainboeard failure be possible right?
i still try to figure that out gonna make a pol thread in DHD general because i have some suspissions to this and i want to see if this checks out.
thanks anyway

[Q] Phone does not boot, red light flashes, is it hard bricked?

Hi,
I woke up to find my note2 stuck on the samsung logo, so i went to the recovery menu and cleared the cache. When I went to restart the phone, it wont start up.
1) Nothing appears on the phone
2) When i press the power button, the red light on top flashes but thats it
3) it doesnt go to recovery mode with the power, vol+
4) it doesnt go to download mode with the power, vol-
5) Battery should be fully charged, when plug into the phone and the wall, nothing happens even when i left it there for half a day.
6) Switched out with friends battery and nothing happens as well.
7) Plug into PC Mac, multiple computers, nothing happens on the phone or computer. Nothing is detected on that usb port.
Anyone know what I can do to try and fix this before I send it to a repair shop?
Thanks

In switched off condition, if it takes charge then it must be go to DOWNLOAD MODE (home+power+vol.down). Then restock through odin or use 'mskip toolkit'

This phone doesnt have any Volume +/- power button trick. It ONLY has the yellow reset button. Its a pain in the A*S!
Try a few things first.
1) When you hold down the yellow reset button, are you ONLY holding it down for a few seconds, and it vibrates ONCE?
Have you tried holding it down for 10 seconds, until it vibrates TWICE, indicating it has powered off completely, and THEN try connecting it?
2) If step 1 got your phone to power off completely try:
-Connecting your phone to your PC via USB with the volume DOWN button held and see if you get a GREEN L.E.D. If you do you have
successfully entered flash mode, in which case you can simply flash an FTF file with flashtool.
-Connecting your phone to your PC via USB with the volume UP button held and see if you get a BLUE L.E.D. If you do you have
successfully entered fastboot. From here, as long as you have ADB and your devices drivers installed on your computer, you can flash
a boot.img or "Kernel" with a fastboot command in a command window (fastboot flash boot boot.img). The easiest way to get a kernel or
boot.img with a baked in recovery is to download the latest Cyanogenmod, unzip and extract the boot.img, and flash it via fastboot.
Since you have an unlocked bootloader already, your device should be able to use an AOSP kernel.
From there you should be able to at least boot into recovery, and flash something from your SD card.
Id recommend just flashing the latest Cyanogenmod just to get your device up and running. From there you should be able to follow steps
get back to stock if thats what your looking for.
I hope at least one of these options work.
If not, like that last guy said, take it to a service center and get it checked out.
GOOOOD LUUUUCK!!

All ZL's are like that. Hold down till 1 vibration for reboot. Hold down till 3 vibrations for power off. The yellow reset button will not power on the device however. I figured I'd check just incase my power button decided to go for a sh*t.
