[Q] unable to get epic 4G into download mode

i had to put phone back to stock and now i cant get the phone to go into donwload mode by pressing 1 and power button. is there another way to get into download mode?
Thanks in advance,

Pull out battery, press power button with battery out, hold it for a few secs. Put battery back in and download mode should work again.

i tried that and still nothing , it just boots up like normal. no download mode.

is there another way to get to the download mode?

tried to use computer as power source on laptop and desktop but no luck any other suggestion/

Are you pressing and holding the 1 key on the keyboard and THEN add pressing and holding the power button? Order is important.
Does your 1 key work?

1 button seem to work fine when trying to make a call . im lost

You didn't comment on my advice, did you give it a shot? I've semi-bricked my epic and that was what worked for me.

When you say stock, do you mean el30? And is it rooted at least? Or does it have cwm? Maybe just maybe, but I think some custom roms had the option to go into download mode when you shut it off, if its rooted, perhaps you could install cwm from rom manager, boot up cwm, install a rom that has download mode from reboot, I think cwm from acs might even have reboot to download mode? Not sure on this one, just trying to go out on a limb and help if I can.

take the battery off...and keep it off for about 10 mins, and then put the battery back in, and try it... i do know this worked for me when i semi-bricked my phone. don't have it plugged in, into anything.

[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.
Sent from my SGH-T989 using xda app-developers app

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

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

[Q] Unable to flash kdz or root phone

Hi everyone.. i am having a strange issue here.. whenever i try to flash my phone using lg software update, everything goes well till the time phone restarts to upgrade. phone should go into software update mode but never boots up.. then i have to forcefully shutdown phone by holding power button and then phone restarts normally . previously i unrooted my phone .. and again tried to root it and failed.. so downloaded new kdz and tried to flash it but failed... i tried emergency mode bu holding up and down volume key and inserting the cable but nothing happens , seems like phone is not going into software update mode.. Please help..

you must come into download mode
phone must shut down! then vol + and - hold (NO POWER) and connect with the usb cable
1sec. later you must be in download mode :/

Can't get past download mode screen

So my problem is for some odd reason I can't get into the actual download mode. I get to the screen where it says click volume up to continue, then when I click volume up nothing happens. And my volume keys work 100% I can get into the stock recovery mode just fine and move around, but can't fully get into download mode. This is getting frustrating because i'm trying to root my phone.

Once it’s off, you need to press this button combination: volume down, power button and home button. Keep them pressed until the download mode shows up. Once you’re there, you will be requires to press volume up to enter the download mode or volume down to cancel and reboot the device.

Has anything happened with the device that would alter your DL mode ??
Using Odin prior to a failure for example ??
Very odd error ...and one I've not heard of before now ...given the fact that DL mode works 50%...
It is possible that the partition is damaged some how ..but a fix is a level below Odin itself ...and to my knowledge would be factory level repair if DL mode won't function...
Sorry I can't be more help ...g

Don't know if it will work, but you could try using kies to do an emergency firmware restore. Don't know if it will fix download mode though.

Thanks, I thought it might be something beyond my repair. Umm the only thing that happened to the device is the usb port is damaged and only charges. I have ordered a new USB port because the repair is very easy. Then after it's fixed ill try to adb reboot download and see if that works. My only question is do you know if the adb command reboots to the same screen or if its reboots to the actual download mode, so in theory it bypasses me clicked volume up.

[Q] Galaxy T989 Black Screen/ Bad hard reset/ E: sig verification fail

i have a tmobile galaxy s2 sgh-t989. i did a hard reset on the phone and something went wrong. When it rebooted and powered on i now have a black screen and a no sync error in little box. the time, bluetooth, wifi all still work. My computer doesnt recognize the phone is plugged to usb, So using odin isn't working. the phone won't go into DOWNLOAD MODE. i have kies, samsung drivers all installed on pc. I have tried using a sd card and using .zip files to recover. "E: signature verification failed" error is all i keep getting when trying the sd card method. i believe the rom is stock, ANDROID SYS RECOVERY <3e> blue screen comes on when holding vol+/-. is my phone a brick or can it be fixed is my question. i dont want to keep wasting my time if this cant be fixed.

You will not be able to flash anything in stock recovery. To get into download mode, unplug the battery, plug into computer with Odin opened, hold power and two volume buttons, insert battery. You can then flash stock ROM in Odin.

The jig should work. I found that it works better to hold it in passed the vibration until you see the download mode screen. And it is plug USB into computer and phone without pushing any buttons and then hold the 3 button combo in. If you want and easy way to root and install custom recovery once you are all fixed up, just let me know and I'll send ya some instructions.

How to use jig
- Turn off your phone and pull out the battery for 2 seconds.
- Put the battery back in the device and don't turn it on.
- Plug the jig into the micro USB port on the phone.
- After about few seconds, your phone should boot up automatically and bring you straight into download mode.
- Unplug the jig.
- Connect your phone with USB cable to computer and then flash your phone via the program "odin".

FWIW, you only have to push both volume buttons when plugging into the computer to get to download mode.
