[Q] Can't get into Download mode - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
The 3 button combo to get into Download Mode is not working on my SGS2. This only started happening 2 days ago when I had a bad flash on Odin as I was installing a stock ROM.
The only way I can get into Download Mode is through a USB jig, which is frustrating.
I can get into Recovery Mode using Vol Up + Home + Power.
There are no issues with my buttons, the volume down works fine as does the Home button when the phone is on. Anyone have any ideas what's gone wrong?
Thanks
psb.

Bump, any ideas guys?

Hi,
No I haven't. Do you know where I can get a 3 part ROM? Intratech's thread only has 1 file to install.
Also, why would that solve this ?
Thanks

Flashing things shouldn't be able to break download mode, it's in a protected part of the system, otherwise it'd defeat the purpose of it being there.
No idea how to fix though.

Hi, thanks for the response. I didn't think reflashing would solve anything. If anything, it looks like a hardware problem because I can get into Recovery but not Download mode. But the vol-down button works FINE when the phone is running :-/.
Anyone else have any ideas at all?

Just a thought, but the galaxy s2 from Tmobile has a different key combo to enter download mode. Perhaps your variant is similar. I believe it is volume up and volume down at the same time plus home but i am not sure so it is worth some searching around.

[Q] Messed up Vibrant t959 with i9000 rom. . . assistance in fixing please?

Alright.. was half asleep and put the i9000 on my t959. Used odin, re-part'd, the whole nine yards.
Obviously, i can not root it using the update.zip method. When in recovery down is up, up is down, and power button does NOT select. So i can not apply it. I am quickly learning everything i need to work on this. However, I need some pointers, maybe hints on where to proceed to get this back to at least a semblance of "working". I tried to flash back to a standard rom, and i get constant recovery-boot screen. Odin back to the i9000 and at least the phone boots fully.
I need to get this back to at least a semi-original rom so I can root and apply the correct t959 build to the phone. Sooo... help a newb out. I have spent the last day and a half downloading trying various options, going in all directions, and getting nowhere. I have attempted to apply via Odin, and borked things up pretty good, but not so much I can not recover, just need some directions. I have just rebuilt my laptop to a standard XP Pro with all updates, and patches. Updated Java JDK, the Android SDK, and Kiess. I can attach and see the phone using ADB without issue. As best I can tell, i have a "clean" kitchen setup to do what I need.
Please help a new get his feet wet without drowning this time!
Thanks guys.

go into download mode by (with the phone off) holding down vol up and down and plug in usb cable. Then flash jfd (which is found in vibrant bible) stock firmware via odin.

This, just ODIN back using this link I guess:
http://androidspin.com/2010/08/09/how-to-restore-or-recover-your-samsung-vibrant/
Just make sure you DO NOT select repartition and take out your SIM card... You don't need to select repartition unless you really **** your phone up.
You guys are brilliant.... and i am sure a few hours sleep and some caffiene helped a lot as well...
Back to the stock t-mobile, no issues no hicups.
Been scouring the bible, and playing around with some roms. Using the search a lot better, thanks for the patience in a moment of panic.. you all are great!
Now to get back to trying and turn this thing into a real decent phone again
Time to feed the custom rom addiction some more!

[Q] Recovery Mode

Hey everyone, I just got a samsung galaxy s II i-9100 and I am having trouble getting it into recovery mode. I have tried holding down the power, home and volume down buttons. What happens is it goes to a screen with a green android dude that says downloading and do not turn off target. So as it says I have left it. This has been over 5 mins of waiting and still nothing has changed. Am I doing something wrong do I have a defective phone I sure hope not. Please anyone help!!!
Wrong = YES.
Instructions for recovery mode are always PWR + Home + VOL Up release Home + Vol up when you see the first splash screen followed by power .
At least you have found download mode .
jje
off your phone .take out the battery.put it back. hold volume down ,home and power untill u see something on screen snd immediately relesse power button,continue to hold volume down and home

I guess what I am trying to do is more complicated than just putting my phone into recovery mode.
What I am trying to do is flash a new rom. I used to have a captivate and rooting it was way easier than this phone SG2. I am trying to put Cognition rom on my phone which I have already downloaded. Can anyone help me first root my phone???

Before installing cognition, you should root your phone with insecure kernel as same version (or close) to yours.
The key combination you said in your first post is the Odin flash mode, this is the download mode to use with Odin in order to put a new kernel and/or a new modem version and/or a new custom rom... When you are into this mode, if you don't start flashing or downloading anything, this is not a issue to stop by pressing few seconds on power button.
Thanks a lot. I finally figured it out!!
k so i got cognition installed without a hitch yay!! but when i went to use the stock email app, i need to re-register my gmail address which i understand BUT it keeps wanting me to register social hub so i click ok and i agree to the terms and conditions but it just pushes me back a screen and says you are not registered social hub user, to register continue to the next page. so i click ok and then everything just repeats!!! Anyone come across this before or can anyone help?
did you ever solve this issue of "you are not a registered social hub user"?
as i now have the same issue

you are really not giving a lot of details here...all you are saying you tried installing a rom and then it froze halfway..
Are you rooted firstly?
If you are have you flashed CF-root kernel?
How did you try to install the rom?
More info and then more people can help you out buddy..see if you can get into recovery and restart your phone.
well... if you've tried "every" (its not like there are a lot) button combination... then just go buy a jig from ebay and force it into download mode...

Nothing from what you said would help..
He obviously flashed it with Odin, and he said he's getting a yellow triangle with a computer behind it..
From what I understood, he could get into download mode.
So just boot into download mode and flash stock ROM. That should do it.

anyone else seeing an increase in the "i bricked my phone" threads?
dont think its coincidence they are increasing after the american variants have been released. People need to check what model they have before flashing things.
OP: not saying thats what has happened to you as you dont say if you have the i9100 or not, hopefully you do.

its ok and same goes by my post as well buddy..we all been in his position one way or the other
1st - Your phone is not bricked if it show an image. Whatever image it is. The only real software way to brick your phone is to flash bad bootloader or stop a bootloader while they are being flashed. However, Bootloader are flashed first. So if your phone stoped half way, you should not have trouble too much.
Remove the battery from your phone for like a minute, then reboot your phone in download mode (vol- + home + power and when the phone light up, release power.) Then flash another rom from odin.
Also, what rom did you used ? If you flashed a rom for another phone, then you might have flashed bootloader for that phone on yours, which is bad. In this case you will surely need a JIG.
sorry im new to this whole rooting/flashing thing. i downloaded the lightning rom: http://forum.xda-developers.com/showthread.php?t=1095274
i have never rooted or doneanthing to my s2 before. all i did was follow the instructions on the page and thought it would be all good? it froze about a quarter of the way there in odin so i just took my phone out.
I usually find from this state I can get back to bootloader or download states
push and hold vol+ and home then power for bootloader
push and hold vol- and home then power for download
sometimes the phone can seem to freeze a little or even die (this happened to me loads on the galaxy s and once already on the s2) and removing battery sim etc or attaching the charger can jog it
however as other have said a JIG is your friend if for no other reason that even if you recover without it, custom roms up the rom count which some twitchy carriers might invalidate your warranty for, the jig will reset this
you can get them from ebay for less than £3 delivered, or there are instructions on this site for making them yourself if you are so inclined.
simply search 'galaxy s2 jig' on ebay mine was delivered today from portugal as I am way too lazy to make one and only wanted a counter reset anyway

[Q] any way of installing new firmware whe home button broken

just a quick question...
i had previously installed lightening rom on my samsung galaxy s2 gt-i9100. recently i wished to upgrade to jellybean however as my home button is broken/recently stopped working i cannot enter into recovery mode to use odin. kies does not recognise the os so it will not allow any upgrades.
could anyone advise me on any options i might have, im new to all this so i would really appreciate some assistance from the more knowledgeable members on this site. is there any way of breaking into the recovery/download mode without having to go thru the power/volume down/home key route?
thanks in advance for any assistance
Yes there's ways of booting into download mode. I'd advise against it though. Why? Because messing with the software with no escape route is playing with fire. If something goes wrong and you need the key combo to boot into recovery to factory reset, you're toast.
Moral of the story, get the hardware repaired before you continue to mess with the software.

Hopper is right, 'messing' with the phone with busted hardware is asking for a 116gm plastic paperweight. Do the smart thing & fix the button first.

Do you think it's really broken? If I remember right, it's a problem with litening Rom, it had a feature like "enable home button" so it could be a software issue, full wipe before flashing new Rom should fix it...afaik..
Flashing a touch recovery (dorimanx kernel) can also work around this.

No display - wipe phone?

My beloved fell this morning and now the screen is completely black - no display at all.
Got a new one coming tomorrow but I can't figure out how to wipe it. I'm rooted running Hyperdrive. I have a swipe unlock.
I've tried Kies and it can't seem to connect. Does the SIM card need to be in for Kies to work?
Do I have any other options?
Thank you in advance for your assistance.

I'd think you could still pull the battery then try to get into download mode Vol Down + Power then wait a second after you hold that combo to hit Volume Up to continue into download mode.
Then have Odin already up and running and plug your phone in and look to see that Odin sees your phone connected. Then flash away.
That's at least how I'd try it. May take a couple times just to get your timing down.
