[Q] Galaxy s2 won't boot into download mode for rooting

Hi guy's, I would just like to start off by saying that XDA is a wonderful site full of amazing information. It just so happens that the problem I'm having isn't anywhere on this website which leads me to think if I'm the only one who has this sort of situation. Basically what's going on is that I would like to root my T989, mainly to get rid of carrier bloatware, so I looked around the internet and YouTube videos and learned how to do it, the only problem is that I am failing at the first step of it which is getting it in download mode. I downloaded Odin3 v1.85, then while running Odin I held the volume up+down buttons and at the same time plugged in the USB cable, as soon as I do that the phone boots into a screen that is showing the battery being charged instead of going to the warning screen and Windows says that the device was not recognized and the USB has malfunctioned. I did install the Samsung ADB drivers for the phone, I also turned USB debugging on, and I tried three different computers all with the same results. Oh and if anyone wants to know, I am running Android 2.3.6. Can anyone please help me? I would really appreciate it if you guys could help me find a solution to this.
BTW this is my first thread on XDA

Paragraphs are your friend.

I would remove the battery 1st and let it chill for a sec. Replace the battery, and hold vol - & + and then connect your USB cable. Do this in that exact order and you should have no issues.

Also if your PC isn't recognizing your phone I'd try a different USB cable. Sometimes that works.

I had the same problem with my previous sgs2, i tried everything from uninstalling and reinstalling the drivers, used a different usb cable, tried a different laptop and nothing fixed it, if your computer wont recognize the phone after trying everything you can think of, then do what i did and get a warranty exchange, after that my new sgs2 connected perfectly

remember that **** well lol.
TO OP:
There are a couple things you can still try, but chances are slim since you did try 3 different computers. It might have been possible that the installation of the drivers (when you plug in your phone) was interrupted somehow and it left an incomplete installation. You would need to download usbdeview and remove/delete/uninstall (forgot what term was used) everything android/samsung related.
Plug in your phone when it's on in the homescreen or something.. let it sit for like 5-10 mins for it to install everything.. there is like 5 things or so. Now try to go into download mode.
If that doesn't work, make sure you're using the t989 drivers.
if that doesn't work, then install kies
Try to mix and match USB wires and USB ports on the computer.

USB not detected. Urgent Help.

Okay before yall rage at me, I already search XDA+Google. I think I found some answers to it, but there seems to be some confusion about my problem...So I wanna ask you guys DHD/I4G users.
My problem is that when I connect my phone to the computer, my phone doesnt detect USB anymore. this happened way back before, but somehow it worked again.
I have 3 new different USB Data Cables. I tried all three of them to see if it was my MAIN USB Cable Data that was broken. It wasnt.
I tried connecting it to 2 other computers in my house and still no luck.
So when I was searching, people said that this problem can be from...
-hardware problem(broken) (but i dont think its broken cause my phone is still able to charge.)
-rom with bad download.
And there were some suggestions to what I should do...
-super wipe your phone and re-install a new rom
-take the micro sd put it in your computer format the SD card.
-take battery out for 30 seconds then put it back in.
-return to stock
-reinstall HTC drivers
however all those methods did not work at all.
The thing is my phone still charges on whatever USB or Computer I plug it into.
Also, this problem happened to me awhile back but somehow it was fixed..IDK how I did it.
Also sometimes, my computer detects it, but it says "something has malfunctioned).
my phone has never got in contact with any form of liquid. but what i think has touched my phone is heat or sweat from my pants.
Edit: also, I never dropped my phone before.
Is this a hardware problem? because as I said it before this happened to be awhile back but I was able to get USB detected to my computer again.
Can anyone give me more methods/information on how or what I should do to fix it?
Phone details
- Device: Inspire 4g
- Rom: Aospx BR7
- default Ril from the rom
- radio : in my signature
- phone about 1 and half years old

It seems you have already ruled out software and cable/computer issues. It is possible for a device to have intermittent failure. Sounds like a bad sd reader. Charger runs seperate from that.

Could also be the PC hardware. What PC OS are you using?

Have you tried cleaning your phones port?

ummmm all I did was just blow on it(sounds wrong, LOL).
oh yeah and also, i always hear that sound when you connect any USB into the computer. that beeping noise. but only when I reboot my phone.
I could always transfer files by using the Micro SD Adapter, but thats too much work. taking my phone case out, taking out the bottom part, taking out usb, putting it in the adapater, then in the computer....-_-

update.
I kind of found a solution?? if i can take any step further...
So I changed my rom to a sense 4 rom(virtuous). I disabled Fast Boot from there. Now my computer detects my phone but it gives me the notification saying that my device cant be recognized.

U can use software data cable app its free .. and u can nove data between phone n pc wirelessly as long as you are in the same network ...

Try to see if there is damaged pin on the micko usb connector of the phone. Also check if the cable is not OK and finaly choose another usb port of your PC. I had simillar problem and in my case was a faulty USB connector of my laptop.

Well to be honest my pc is new it has like 3-4 months and i rly checked all my usb ports.. back to case, and 4 usb ports on front of case...
The thing is.. cable is new, i tryied with another 3-4 cables and same results, on other phones it works on this doesn't work.. and the weird thing is when i activate USB DEBUGG , from what i know it should happen something.. some pop-up message something idk.. i mean on my samsung when i mark the box of usb debugg it shows me a pop-up message like - USB CHARGE, PHOTO SHARE, DEVICE STORAGE.. something like that...
The phone is new.. is possible to be something from soft or idk.. i mean if it was the usb cable.. phone cannot be charged or i dont know..
Thanks for answer... maybe ill find a solution for this idk...
I was at a Phone Services and they told me.. "Your phone has guarantee and we can't see if the problem is internal or not" .

Well it can be software problem too. I now have issues with the touch screen when I start the camera app. It just freezes and it can't find the front camera like it doesn't exist. There will be firmware problem I think. F**king MTK.

USB problem

Hello, I have problem with USB connection.
When the phone is connected to the computer, the phone starts charging but the notification of the choice of file transfer, charging, etc. does not pop up. The computer pops up message that the device is not working properly.
In fastboot mode, the same message pops up and you can hear the repeated sound of the connected device until the phone is restarted.
The headphones on the adapter and OTG do not work either.
I tried different cables so it's probably not that, I also replaced the bottom board with a USB port but also no effects.
Could this be due to damage on the motherboard? How could I change rom without usb? I have uploaded MIUI alpha 8.5.31

You can try edl mode and if that doesn't work too that maybe a hardware problem

Hey. I read about such problems on one of the Polish forums, and from what I know helped to clear the usb socket on the phone. Maybe it's stupid and will not help but it's worth trying

I have exactly the same problem.
I think if I do a hard reset, maybe the phone reinstall the drivers knowing the new usb board.
Have you solved it?

Clean your usb port with say a sewing needle. The USB port is metal. And silver in bottom. If it's black or any other color it's got lint packed in it. I see this day in day out and is a common occurrence on type c ports

Send a close up picture. Everyone tells me it's clean. They cleaned it. Normally they don't. Flashing from pc ? Wouldn't that indicate a USB problem as well?

My phone doesn't connect with the PC!

When you plug in to pc, phone should pop up a prompt asking if you want to allow the pc to access phone. Keep phone screen on and look for message at bottom of screen asking for access.
You could also check in developer settings under Default USB configuration and make sure its not set to Charging

I know all of this bro! I flash phones everyday! This is new to me. Someone was talking about this in another thread that a bugged software caused this problem and damaged USB port's d-/d+ points. Now i don't have much knowledge on hardware.
Only flashing a software will fix this
