Can't access download mode - Galaxy S II Q&A, Help & Troubleshooting

I've previously installed a stock ROM, which I use to this day.
Now, I can't get into download mode.
I hold down Vol Down, Home and Power but nothing happens. The phone keeps booting normally.
Any ideas? :\
I ask because I wish to install a different stock ROM.

Mine is BRICKED!!! OTA Friday got to 85% and went black. none combo of the Three Button Salute is not working at all. Odin can not see it.
As long as you can get into download mode, your phone is not totally bricked. Vibrants are very very hard to brick. Trust me, I have messed mine up more times than I can count,but managed to fix it. First off, can u tell me what windows version ur using, do u have the Samsung drivers installed, what button combination have u tried to get into download mode. I know you probably tried a ton, bit this will help me narrow down what will and will not work for you.

No download mode at all, no charging screen, nothing at all. Black screen! Power with plug in, Power and Vol up, Power and Vol Down, Power and up/Down. No luck. Running vista. I have used odin before with no problems.

Have Odin open and everything setup on the PC.
Then just take out the battery and make sure your phone isn't connected to the PC yet. Then wait maybe 5 seconds and plug your phone into the USB without the battery in the phone. Then press both volume buttons only and install the battery while holding both volume buttons.

We need a lot more info. What did you flash, how did you flash it. Where did you get the firmware. I ask the last question because according to your profile, you just created this account today. Which tells me you got the firmware elsewhere.

To boot into recovery you want to release the buttons by the second Samsung logo pop-up. And don't plug into computer. That's for download mode.
Regardless, I don't see recovery being much help to you if Odin is not working for you.
Is odin showing that its successfully flashing your phone? After flashing back to stock with Odin, is the siyah logo at least gone?

Yes, but you need to describe everything you did and everything that happened to make you want to flash back to stock. Without knowing what caused the problem in the first place, we can't help you very much. You say you installed many roms (stock, custom). Your phone probably did not fail randomly. There is probably some event or circumstance you can think of, or change you made, just before it failed. Please be specific.

Hold the Vol+/- & PWR button at the same time, when seeing first boot, keep holding all 3, when past 2nd boot screen, release all 3.
There's no PC involved.

Hey everybody
A few days ago i rooted my phone with CF-Root and installed the Super Nexus Rom Stable 1. It run really
fast and worked great :good:
This morning I saw that the second version released. So I downloaded it and also the gapps again. But after installing i recognized
that the screen flashed and the rom didn't run smooth.I decided to roll it back with my backup.
But after starting the backup, the screen got black. I waited 30 minutes, then i took the battery out of my smartphone. As I put it back and started my phone
again, i just saw a purple screen. No samsung logo or somthing else. after 2 minutes i saw the status bar at the top, but the rest of the screen kept purple. I tried to bring it in download mode, but the screen is always purple and odin don't recognize the phone.
Please help me
Did you try entering download mode with a jig? Sometimes even when button combo or cable /volume combos don't work a jig will.

No, i think i should buy one.
I think my problem is that the phone gets into the Download Mode. But at the s3 we have to confirm that we really want to get into this mode.
I think i just hang at this screen, but can't check the right box, cause i just see the purple screen
Get I immediatly into the Download Mode with a jig, or have i also to check the accept button?
charge phone via pc for sumtime then try to enter in downlaod mode
Just because the screen is purple/black doesnt mean that phone is not in download mode.
If you hold the combo buttons to get into download mode but cant see the screen where it says press up to go into download mode just wait a sec and press up anyway.
then plug your phone up to odin.....it may still be able to go into download mode even though you are SEEING the screen.

I started my phone normal and wait some time. Then I connected it to the pc. The explorer starts and show me a window with the title GWT-I9300.
But instead to see any content the folder is absolutly empty. Bad sign??? Or good sign that i can connect it?
I start it again with the 3 key combo in Debug Mode. I think i'm in cause if i connect it again to the pc nothing happened. Odin also doesn't recognized the phone

You should return it to stock with a full flash give me a sec I'll grab a link this will restore everything. You then should go into recovery volume up middle button and power and do a full wipe to make sure you get everything out as odin doesn't do that it will only override what is there.
http://forum.xda-developers.com/showthread.php?t=1646610
Download file from there and just to make sure we are talking international gt-i9300 CORRECT? The file is big like 750 megs it contains stock everything and will restore the entire device to stock. It will not erase the on board store partitioned for the SD heck it doesn't erase anything just overrides.

Doesn't sound like a hardware brick. After you flash the stock again if you still have the purple screen let me know and i'll find the button combo so you can wipe the data as there could still be something lingering that could cause that. And don't be to worried you have a colored screen that's not too bad it's when you get nothing no matter what that you should get very scared

Yeah that's what I thought so last thing
Pull battery
Hold Volume UP Middle Button and Power Button for ten seconds
wait like another 20 seconds then press volume down twice then press power after a min press power again with any luck this will do a full wipe for you. It is blind but I did confirm on my phone the times it takes.
Edit
After you volume down twice and then press power volume down three times and press power again then wait ten seconds and press power a last time. The third press is to wipe the cache which is the problem I bet.
Was there any info about GPU overclocking/volting on that custom rom you installed? I mean on that version 2.
For me this sounds like that your graphical chip on the phone might have damaged.

It could be but lets not scare the dude yet. I have had many phones do blue and purple screens just as he describes it is generally a bad flash or file or forgetting to wipe. I do not think at this point we are looking at a bad GPU. I have also had this phone give me weird colored screen flashed upon starting or going into recovery that had to do with a improper restore.

keep playing with it after you are sure you've gotten the three and two try to odin one more time.
Another option you have is to go into odin and and flash a know stable recovery then see if you can boot into it recovery.

Pretty weird...No download mode

Hi guys
I'm facing a problem i'm not very comfortable with...
Just bought for my wife a Galaxy S2 running Gingerbread 2.3.5.
I planned to root it and migrate him later on to latest Sammy on JB...
As per many tutos, to root the tel, you inject ( using Odin) the right CF_root from chainfire once the telephone is in the so called download mode
and here comes the problem...Vol- & Home & Pwr do nothing...It just boots the tel...No DL mode at all !!!
Are there GS2 around with no DL mode ? or is there a way to force this DL mode ?
( I've tried a suggestion which did not work..i.e remove batt , wait 30s, press vol-,pwr, home and reiensert batt without releasing the keys)
Any suggestion more than welcome

Tried a USB jig? They are intended to force DL mode. Never used one myself though. What you've already done would have been my first port of call. Also, have you tried recovery mode? (Vol up, Home, power). That way you can tell if its the vol. down button thats not recognising the keypress. On my tablet, that's the case, it takes a bit of poking/fiddling to get into recovery mode as my vol up button is sketchy.

You can try something.....turn off phone,and pull out-reinstert battery.Don't turn on yet!Now start pressing and holding the VOL DOWN button only.With phone turned off,and pressing the VOL DOWN key,put in charger.Keep holding the button,until you see Download mode.If that doesn't work,maybe VOL button is faulty.Also,try a Jig.It has to work
Yeah...the USB Jig was THE solution...and without yr suggestion I would'nt have had the idea to use it..and this for a good reason...My own GS2 does not react to USB jig ( the only solution to enter DL mode is the key combination) where my wife's GS2 enters DL mode ONLY with this Jig...
So one more time, thks to you all...

Ah this is ennoying...because it means that, now i'm on JB 4.1.2 this jig may not work properly...
Why do I bother ?
Simply because I have discoverd that this new GS2 has probably an H/W problem i.e The Vol Down key seems to be dead and that leads to another question Are the Vol keys simple H/W stuff, establishing contact or not or is it under software control ?
Browsing PhilZ recovery, I've seen a brief on screen message "Vol Down enabled"followed immediately by "Vol Down disabled" which I've not been able to reproduce..
So i'm in the blue....H/W or S/W problem
BTW, there may be a solution I had not thought to...
the power button , when hit, takes me to a 4 way reboot in which there is among the options, reboot in download
this may be the solution i'm after...and which I'll test as soon as my wife lets me approach her phone...lol
thks fr yr concern
I would be very careful when mucking around without the proper hardware functions. I would advise getting it fixed before continuing. If something goes wrong and you need to use the hardware combo to get into download mode to flash stock, you're stuffed. End of story. Messing with phones with no escape plan is a bad idea.

Mobile Odin will get you outta that button mess. You can always flash philz or siyah v6 with it.
You should get them fixed.

Help - stuck in death! :(

Hey guys,
I was running the newest Paranoid Android 3.60 with DoriMax kernel and decided to switch to the latest SiyahKernel. Unfortunately after installing the kernel through cwm and rebooting all I got was a blank screen after the SiyahKernel logo.
Now heres my problem, normally I would just boot into cwm and reinstall a working kernel, however, I stupidly forgot that my home button is not working! So now I have NO way to boot into cwm and the phone will not boot,
What are my options here guys? The phone is dead?
Cheers
i only see a jig as a solution, which forces your phone into download mode

No,there is a way to enter Download mode.You can try something.....turn off phone,and pull out/re-instert battery.Don't turn on yet!Now start pressing and holding the VOL DOWN button only.With phone turned off,and pressing the VOL DOWN key,put in charger.Keep holding the button,until you see Download mode.
