I was trying to install cyanogenmod and successfully booted into download mode the first time by holding volume up and volume down buttons and plugging in the phone. I installed the driver as per the instructions but Heimdall wasn't working so I wanted to disconnect and try again. My phone works fine after disconnecting, but whenever I try to boot into download mode, it goes to recovery mode instead. Can someone help me boot it into download mode again so I can install clockworkmod? Thanks so much!

You should be able to enter download mode by completely powering down. Next press POWER+VOLUME DOWN+HOME KEY together.

Alternatively, when you power down the phone, hold vol+, vol- and the power button and insert the USB cable to the phone and it should boot up into download mode. (The cable should already be plugged into the PC)

That's what I've been doing, and it worked the first time, but now when I do the same thing, it just boots me into recovery mode.

With phone on and USB not plugged in, hold Power + VOL U + VOL D -- wait 10 seconds until phone reboots, then let go of power button but keep holding VOL -- you'll go into ODIN after a short SAMSUNG screen, if I remember correctly.

this is the first and only root method that has worked for my T989D, ive read literally hundreds of threads from fellow S2X owners who all share the same problem, pcs not recognizing their device and/or not being able to go into download mode...well I wont say this is a guarantee but, I have tried literally everything every single person in every thread has said for advice and in the end, no one guide did the trick completely,but rather a mesh of a few.....1st, back up your phone if you can wirelessly through kies or another online file manager site. 2nd do a full factory reset with stock dialer *2767*3855#(cant be undone) 3rd download latest version of kies for drivers on PC and download necessary files from here:h t t p://mirror41.downloadandroidrom.com/download/GalaxyS2TMobile/rooting/tmobilegalaxys2rootICS.zip?token=800439833 where it says click to download, not on sponsored link, 4th. on phone,in stock dialer enter *#7594# and select "enable shutdown with long press end call" box . 5th, go to settings, then and more... select usb utilities, and press connect to pc,(without cable in phone) then it will say connect cable, do it and select usb storage quick before it disappears, once your sure the phone and pc are aware of each other(in your device list it will be labelled android and not under unspecified) and the icon in your notification isnt going away, hit dissconnect usb storage button and hit home button. 6th, hold down vol+ and vol- together first for a sec, make sure your holding right the middle, and then hold power key until vibration, immediately let go of power key AND AND!!! vol+ continuing to hold JUST vol- for another couple secs until download screen appears, and again same method when booting cwm, I was astonished when it worked, and all because of letting go of vol+ and power at vibrate, again thank you ten fold everyone who gave me tips!

I have a Samsung Galaxy S5 G900F, the fingerprint scanner is for some else's credentials and I don't have their login password etc. ADB is not an option as I cannot boot the phone to enable debuggin mode. I have tried all, methods of booting into recovery including Vul Up + Home + Power, this does not work.

Please help! :)

how quickly are we talking? didn't work for me. where is everyone getting all of their different stories from? who was the first person to start this rumor we could put this phone into download mode. i think it's all a bunch of hogwash placebo. seriously tho, who REALLY knows? i'm tired of reading a million different answers for this question. and don't me something your friend told you who's cousin told him who worked for htc, or was it his cousin i forgot.

Taking out battery and putting it back in does work but i think you have to be very lucky with the timing :/
It worked for me the first time i tried it but after that no :(
And i did the most stupid thing by trying to flash recovery instead of getting root and couldn't even get recovery as it failed.
So i anyone gets lucky with this method get root asap and then in future till you fix this issue use android emulator to get into download mode.
I think to fix this issue one thing you can do is flash stock rom so get root and get into download mode as you wish.

I'm having this problem, or one similar. My phone vibrates when I try to boot into download mode, but then after like 7 seconds it just boots into normal mode again. I was able to boot into recovery mode, just not download mode.
