Can't enter ODIN dl mode

I have a galaxy s2 and I cannot get the phone into ODIN download mode. When I plug in the USB, while holding the down and up volume button it goes into recovery mode A3 but no DL mode. I can't get a USB connection to the computer for the phone to be recognized so I was trying to get into ODIN DL mode to see if I can get a connection this way but no luck

Are you trying to recover from a bad flash? Did you already root your phone? Did your try to wipe cache/factory reset from recovery? Is your phone unable to boot?
No
I've never flashed the phone before, it's not rooted and there is only the built in recovery mode. I have factory reset once but its when I first got the phone.

Did you try turning off your phone, pulling out the battery for a couple of seconds and then, press power + vol(+) + vol(-) and release the power button when it vibrates once?
Yep

Basically, with the SGH-T989D, pressing both volumes buttons at the same time while loading will bring you to the recovery, but it's not supposed to be the same with the SGH-T989... Did you tried booting while holding only 1 volume button, bottom or upper?

1-use ODIN to flash cwm (clockwork mod) & root your phone First
2-after that u flash any custom ROM while in cwm.
How:
1- your pc has to have samsung usb drivers (one way to do that is to downlaod samsung Kies)
download to your pc these files:
“recovery-cmw-hercules.tar”
CWM-SuperSU-v0.87.zip
get them from here http://galaxys2root.com/t-mobile-galaxy-s2/how-to-root-icsgb-on-t-mobile-galaxy-s2-sgh-t989/
Now, to put phone in download mode: Turn phone off- take battery out Then put it back in- hold vol+/- down & plug usb cable in phone
screen will come on- move vol up -----> u in download mode. (at this stage only usb cable or you following steps can make this not work)
Start ODIN........u can see the rest from link above.
After phone is rooted and has cwm installed Now u can copy any ROM to scdard and flash it through cwm.
to put phone in cwm (recovery) same as above except Hold vol+/- & power button (no USB cable) samsung will show up on screen Let go of power button and keep holding vol+/- ----> now u are in recovery ....install your rom + gapps and reboot
Two importand thinhs: after rooting and installing cwm ------back up your current rom & make sure make sure you flash ROMS for your device (Hercules) only ....u flash a rom/kernel for another device YOU WILL brick your phone,
after the first time....its super easy
Hit thanks

Pull the battery, plug the cable into the phone, Hold the up and down rockers, put the battery back into the phone and power it on while holding the rockers. A yellow screen with a warning will come up. Pressing the Up rocker will get to DL mode. Pressing down will reboot the phone. But unless your phone is connected to the computer/power, DL mode is difficult to get to. Hope that helps
when do you put the battery back in?

Can't use hardware keys to reboot into recovery

I have the t-mobile LG G$ (H811) and can't use the hardware keys to reboot into recovery.
I have CM13 and TWRP installed (previously had CM12.1/TWRP with the same issue).
I can use software to reboot into recovery, but not the hardware method.
I have tried all the combinations I can find, basically consisting of:
-turning on and pressing the power + volume down or power + volume down + volume up
-releasing power for 1 second when the lg logo comes up
-pressing the power again
No matter what I try, the phone continues to boot as normal.
I can easily get into download mode though
Is there any way to reboot from download into recovery?
I had a problem with a bad CM flash that bootlooped (not the bad lg bootloop problem) - and my only way out was to re-flash stock and go from there - it was a time consuming pain. I am just trying to figure out some way of booting into TWRP recovery - I can't seem to get the recommended keypress sequence to work.
Any assistance would be greatly appreciated.

Real hard, but I finally got it to work. It is all a matter of timing. Power button needs to be released (and pressed) before the unlocked bootloader message comes on, but not too soon.
Even knowing that, I still only get it right 50% of the time.

I found this sequence to work best for me.
First hold volume down then press power down
When the logo shows up, release power and then press again.

BootLoop post Viper4Android module on Magisk with Lineage 15/Oreo

Lineage /Oreo was installed thru TWRP 3.xxx, running fine but unhappy , no Viper4Android , so I installed it as a module on Magisk,
after installing the driver, was ask to reboot as directed, but went into bootloop , stuck on a boot loop " Set Warranty Bit : kernel " top left corner and Samsung Galaxy Note 3 on screen ; I tried Vol Up +Home+ power combo and all other combi I could think but no luck , Odin wont recognize my phone, tried Samsung 300k tool with no luck, I fell like a newbie after using so many ROMs on all of my devices, I google how to get back to download mode but no luck, I need help to make my Samsung note 3 work again, PLEASE. THANKS.
Hi,
I have same phone but I'm running Resurrection Remix 6 which is based on LineageOS 15.1 and I'm able to use the Viper module through Magisk 16.3 without any problems. No bootloops, no nothing.
I never would have guessed that a sound mod could brick the device to the point that the buttons no longer function. Hopefully other users will chime in and help you fix it.
Best of luck.
EDIT: Try taking the battery out to force it to shut down and then try the recovery/download mode technique again. Sometimes, it'll end up in a bootloop and the buttons will be become unresponsive. I know it may seem a bit strange, but that scenario is entirely possible given the age of the device.

You need to take the battery out to force it out of the bootloop then push volume DOWN, home & power.

Sorry, I mean Vol down but no luck.
You may have to try a USB jig to get into download mode.

Can you also not boot into TWRP by holding Home+PWR+Volume up? If so you can boot to Download Mode from there.

The jig that I bought didnt do anything so I make my own, I can go to download mode now, installed this ROM/firmware N900TUVUCNB4_N900TTMBCNB4_N900TUVUCNB4_HOME.tar.md5 succesfully but wont go pass beyond the tmobile logo, tried a few more firmware and lately this N900TUVUFOL1 and also , am stuck to Tmobile logo, anybody knows which firmware would likely bring my note 3 back to life, thanks in advance.:
Try this:
Uncheck everything in Odin except f reset time. Flash the latest ROM again. When you see the word "reset" in the status WIndow, remove the USB cable from the phone, remove the battery, replace battery, boot into recovery mode using buttons, factory wipe, and reboot.

After "reset" status, I did remove cable, remove batt and boot up to recovery, the blue light lit up as if its going to recovery mode , android logo showed up but phone boot up to normal but not pass beyond tmobile logo, so I did CF-root via odin , but still not booting to recovery.
Try flashing the entire ROM in AP.

Thanks Audit13,
I manage to restore my Note 3 to TMobile Android 5 using repair firmware , it looks like I wipe out the partition ,My phone runs like new, am just wondering why I cant go to Download mode with button combinations of Volume -/Home/power , tried to install twrp via Odin, it says PASS but Vol +/Home/Power wont lead me to bootloader, did tried CWM , it will boot up but before I could start using it, it will reboot to normal and I could not go back to bootloader with button combo Vol+/Home/Power........HELP...
Download mode is volume down+home+power.
To flash TWRP with Odin, try this:
Open Odin and only check f reset time. Flash TWRP. When you see the word reset in the Odin status window, remove the USB cable from the phone, remove the battery, replace battery, press home + volume up + power.
N900TUVUFOB6_N900TTMBFOB6_TMB and N900 PIT - are the files am using after screwing up my partition( I dont know how I did that ), this Note 3 is running like a hot knife on a butter BUT the only bug I notice is Volume Up + Home + Power ( recovery) NOR Volume Down + Home + Power (download ) does not work, I can only go to download mode using a USB JIG and no other way. I can flash TWRP via Odin with Auto-reboot not ticked , so I could remove cable, battery , hoping to get me to recovery mode but I couldnt. Did I miss a step?I need help.

Recovery-mode only, is there any hope?

[SOLVED] Download mode can't be removed, I had to try all dat long but I finally could boot into it.
Hi,
So... I had a working Samsung Galaxy S9 (SM-G960F/DS) running Lineage OS yesterday. I noticed something wrong related to the mobile network in my country (FR) and decided to flash the correct stock firmware matching the country code XEF before doing a full LOS reinstall.
Fast-forward 20hrs of download, I perform the flash operation this morning using heimdall(1) and reboot.
Now, the phone bootloops. I can't get into download mode as usual, and the only thing that is available is the stock recovery mode that allows:
apply update from adb
apply update from sdcard
wipe data
wipe cache
mount /system
view logs
run graphics test
I have a working all-countries firmware archive that contains the one that was working previously (minus the mobile network problem). But since I don't have download-mode anymore I can't install it. I tried adb sideload (which is available via the "apply update from adb" option), wipe data/cache to no avail.
Is that hard-brick? Did you ever experience a similar situation? I think there's no way out of this but any advice would be appreciated.
Thanks again!
You should be able to get into Download Mode (Vol Down & Bixby & Power)
Keep trying, try keeping hold of the button combo until after the phone reboots twice hopefully the second time into download mode
Download mode has nothing to do with firmware or recovery that has been flashed, and if you can enter recovery mode, it doesn't sound like a hardware problem either
And use a Windows machine & ODIN 3.13.1 to flash stock
Unfortunately it doesn't seem to work, i tried many tiimes and I usually can do that very easily. It seems flashing the corrupted images wiped it out.

Impossible as it is not part of the firmware, nor can be touched by firmware, it is part of the hardware (Think BIOS vs OS)
You can even 100% wipe all internal storage clean so there is no OS at all and download mode will still work fine
Keep trying
Okay I guess it's possible that the download mode is still there but I can't reach it.
I've been trying hundreds of times every combination I can think of (including Home + Vol Down + Power that used to work).
Any alternative way to trigger the download mode ?
How are you trying Home? There is no physical home button
The button combo is Vol Down & Bixby & Power from a powered off state
Keep a hold of all 3 until it hits the Warning screen, then hit Vol Up to enter Download mode
No other way to access it that I know of, USB Jig hasn't worked since a few models back
Have you tried factory resetting from inside recovery? Unless you used CSC during the stock firmware flash, that could be a reason for the bootloop

Maybe the issue is with the Volume Down button, does it work inside of recovery for navigating the menu ?
What happens when you try entering Download mode? It just tries to boot as if you didn't press anything?
Only other thing is to hold Volume Down & Bixby, then connect the USB cable to power it on (instead of using the power button)

The volume down button works perfectly in the recovery menu.
When I try entering download mode normally while device is powered down, the phone never turns on.
When I try to hold the buttons during the interval of the boot loop, it goes to recovery (yes, even with volume down, not volume up).
The other technique you mentioned also went to recovery.

BINGO! I kept trying. Did this all day literally hundreds of times.
And it just worked.
I didn't change the way I do it, I think there was some nasty timing going on with the boot loop.
Anyways... lesson learnt: download mode is indeed hardcoded. What a day!
Thanks for being so helpful!

First of all dude, since your bootloader is not unlocked how you can access it's fastboot mode!? I don't get it. Also, you simply cannot root your device without unlocking your bootloader since it requires fastboot mode to work.
Well, if you can access your stock recovery mode by vol+Power button I recommend you to format data and install latest package from Realme software download website! Or service centre is the final option!
If your phone is stuck on the Realme logo and never boots and only restarts and shows logo again in a continuous circle then press and hold volume+ and power button until the phone shuts down. Then press volume- and power button and hold until you get into fastboot mode.
From fastboot then use the1) volume button to select Recovery 2) then press the power button to go to recovery 3) then select how you want to flash the stock rom (either download ROM from internet, flash from ROM saved on you phones storage)
