stuck on "downloading" screen

Hi all,
I just trade my old phone for a tmobile gs2, everything was fine until I decided to do a factory reset, now I'm stuck on factory mode with a screen saying
"product name: sgh-t989
custom binary download: no
current binary; samsung official
Downloading...Do not turn off target!!"
What should I do? Help please, thanks in advance.

Hold the power button for 10 seconds.

Hi Alphadog32,
If you can still look at this 3-yo thread, can please help with a variation of this problem?
The same Download mode message came up permanently after I simply rebooted my GS2. It has been running a branch of AOKP 4.4.4 ROM for about four months. It had occasional problems - apps sometimes crash randomly and data mode sometimes goes down to EDGE until a reboot. I rebooted it because it was stuck in EDGE data mode again.
I held it for 10 seconds while the Up/Down Volume buttons. The phone started vibrating constantly both times until I let go, then came up to download mode again. It did not respond to Volume + key.
I also connected to Odin 3.07. Windows says that the last USB device has malfunctioned and Windows cannot recognize it. Hence Odin also does not see the phone on any COM Port. I am plugged with OEM cable.
Since the phone is running a non-Samsung ROM, maybe I need to install USB drivers other than Samsung's to have Odin work?
If so, which ones are correct?
Can you suggest anything else?

[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.

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

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
Thank you again! All this time I was doing it wrong way!!!

Stuck in charging
Hey Bro My Galaxy s2 stuck on charging .
not getting ON .
at download or recovery mode .
when i unplug the charger . my phone even dont start ?????
Sorry for my english

Phone wont turn on or charge, but makes a chime when connected to my PC

Hey so two days ago my S3 crashed and wouldn't turn on again. I've tried the home button + vol up/down +pwr and nothing. I've tried putting i another battery, still nothing. When I connect it to my computer it makes a chime so its recognizing it.
I bought the phone from a friend like a year ago it was rooted and was running task650s rom. It hasn't been updated for like 6 months though. How can I hook it up to my computer and flash the stock rom if I cant get it into download mode?

Bootloop/ wont connect to Kies

Ok so, Galaxy note 2 Gt-n700.
One day randomly turns off (not rooted/flashed). Go to turn the device back on and it gets stuck in a boot loop on the first screen, keep rebooting till it ran out of battery.
tried to go into recovery mode Vol up +middle +power. Nothing.
Then tried the other one.. Vol down + middle + power
hit continue at the firmware install and get RPMB: INVALID RPMD Data
Now googling this comes across alot of advice for PIT files and ODIN. when i tried to "install" this it comes up with an error that i cannot remember at the moment on ODIN basically saying cant its broke.
I have now got the phone saying that there is a firmware update and to connect to KIES and do emergency recovery. The damn phone will not connect to KIES and i have reinstalled KIES and all the drivers 500 times. Tried all usb ports.
Now im about 5 minutes from throwing this phone off a wall.
Can anyone help.
Much helps needed.

What ROM did you use before that happened?
If you not on 4.3 bootloader, try to flash oldest stock, one file, firmware through odin.

Is your phone still going in bootloops?Try to enter download mode by pressing volume down+home button without pressing power and see if still goes into download mode.If it does then your power button is faulty.Two scenarios to that either power button is stuck on "pressed" mode which you can resolve by taking out the cover and screws and pushing out the power button (look up youtube video) or worse the power button needs to be replaced totally.If power button is working fine try what the above user stated flash the previous working stock version or flash the latest 4.4.2 stock ROM and see if it bootloop is resolved.

im having the same problem how did you fixed it ??

Phone bricked, no download mode, can't recover

So, as the title says. My phone decided to do a little update through OTA. All fine, all good.
However, during the update it suddenly switched off and rebooted. Then a nice screen popped up with the ominous message: "An error has occurred while updating the device software. Use smart switch to restore the firmware". Great!
So, hooked up the phone to that app, but it says unsupported device. The emergency recovery list also remains empty. Thus, a little Google-fu later and it seemed I could also do it with Odin. I know Odin, so no problem.
Downloaded the latest firmware with Frija, extracted, loaded into Odin. Then, I tried to enter download mode by holding vol up+down while plugging in the device. No dice, still the error message. Tried it countless times with different timings, but it simply will >not< enter download mode.
I cannot turn the phone off either. Anyone knows what to do? All stores are closed for the next 2 months due to Corona so I have no phone at the moment.

ohhhhh wait to open samsung store to fix

power button & volume - for 7 secs , release when it vibrates , and immediately power button ( for 1 sec and release ) & volume + ( keep pressed ) , to get into recovery
From recovery there is an option to get into download mode
Requires perfect timing , yes ! but you will get it right
Cheers

The buttom combos do no longer work. It seems there is no download mode or recovery anymore.
Anyway, the phone now completely died on me so I have to sent it in for repairs. It will no longer even charge or turn on anymore.

Did they repair it?
I'm having the same problem. Ugh. Can't get into recovery mode

To go into download mode at least on the n975u model you turn off the phone then hold volume up and down and insert the usb cable. It should boot into the download mode.

here is the solution
keep it running to empty out the battery
make sure its dead by powering up ur device
if u r sure its dead, keep pressing the combo and connect u r device to pc.
congrats,

And from there i think if you plug it in to odin you will find that the phone is still in download mode despite not showing the correct screen. Ive flashed firmware before with the triangle warning screen on instead of download mode, it works fine. So long as there is a blue indicator showing in odin then you can flash the device.

This is the actual answer. The error that op originally got is still in fact download mode.

My brother you saved my life thank you

To anyone coming across this thread, I had the same issue as OP. Bought a "new" Galaxy S10e SM-G970F which turned out to be SM-G970N. Everything worked except updates, but I managed to flash the latest version through ODIN.
A few months later, when I tried to flash a new version, the ODIN transfer stopped mid-way and the phone rebooted to a lightblue screen with korean letters and "Smart Switch" written in English. However, Smart Switch declared that the model is not supported for reinitialization.
I tried to reach download mode somehow, as the phone could not be turned off using a key combination or via PC at this state. What @GeeAyeZee and @pcriz said is absolutely correct, THIS SCREEN IS INDEED CONSIDERED DOWNLOAD MODE.
I persisted with ODIN, trying to flash the new version 2-3 more times (rebooting the phone and PC between attempts) until eventually the process completed! Phone is unbricked. Hope this helps someone.
