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?

[Q] Need Help - SM T705 stuck on start up screen.

Greetings XDA Developers,
Newbie here. I own a Samsung Galaxy Tab S (SM T705). I was able to root it a few weeks ago and I decided to install a custom recovery (TWRP) using an app from the Playstore named "TWRP Manager". I didn't hesitate to do so using this method because I was able to install TWRP on my GT I9300 successfully from the past using this app. However, after being prompted by the app that the recovery was successfully installed and needs to reboot the device, my tab was stuck on start up screen ( See attached photo ). I tried long pressing the power button but nothing happened. I waited until the device ran out of battery and when it did, I plugged in the charger and I'm back at the same screen. After google-ing some possible solutions, I tried to boot it into recovery but was unsuccessful, however, I was able to boot into download mode.
I'd like to ask for the help of some "experienced" users in this forum on how to solve this problem. And if possible, I'm hoping that flashing a stock recovery using Odin wouldn't be my last resort.
Thank you in advance.

Your going to need some fast hands for this one! I've ran into this lots of times when testing kernels and such. Any force reboot by holding Power Button+ Home Button + BOTH Volume buttons all at the same time. Press and hold that combo until the screen goes black. Then once the screen goes black quickly press and hold Power Button+ Home Button + Volume down buttons all at the same time. You should no enter into download mode. You said that you drained the battery so I would suggest charging it in download mode for 30 minutes or so then flash TWRP with Odin.
Your going to need to flash stock recovery or TWRP with Odin to override the boot and get it working
The TWRP app doesn't always work in which is why I use Odin.

As a side note for future reference, hard reset is simply hold POWER + VOL DOWN.
As said all you need do is boot to download mode and flash recovery.
If you're on lollipop you may need to immediately boot into recovery after flashing to make it stick.

Hey, thanks for the heads up. But how exactly do I "immediately boot into recovery after flashing to make it stick." Since after I flash recovery via odin, it would obviously automatically reboot my device? sorry for the dumb question.

Both are the same I think. Some people name it by our product name or device name (one has xx and one doesn't. Both are the same)

You either be quick and hold POWER + HOME + VOL UP as soon as it reboots or you uncheck auto reboot in Odin then restart manually.

So did the solution work? I am looking at a SM-T705 on ebay being sold for parts with similar symptoms. hoping I can fix it for a great bargain.

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!

Good stuff, yea well whatever it was hopefully it's sorted now, use ODIN this time

"Recovery Mode" for "Clear Cache", etc.

Has anyone figured out yet how we're going to get into "Recovery Mode" now with the "Bixby Button" missing? I used to "Clear Cache" weekly and thought of it this morning... don't dare experiment and "Brick" a brand new phone - hoping someone with insider info had some data on the subject? Thanks in advance!!!

Power off, then power the phone on while holding volume up and power (bixby) button together

Also works on Sm-n986b [Exynos] bit not on 9860 SD, it works only if you plug on pc via USB, it may be a Bug

Power off phone wait few seconds hold both power and up value button same time for 10 seconds. Bam your in recovery mode. Worked for me N20U1 Unlock Snapedagon chip.

Hello guys
Im in the same situation, i cannot boot anymore in the stock Recovery mode.
I booted one before, then i changed CSC with Samkey and i flashed lastest unbranded firmware with Odin. All the processes were successful without problems but the combination Volume Up + Power doesn't work anymore, i tried every combinations.
After booted up normally despite holding the Recovery combination keys, in the homescreen a grey pop up say to me: [PDP] Back-up file detected.
My Note is an SM-N986N - Snapdragon
Any suggest ?
Thanks

You must connect to pc with usb cable and then try

Same here! HK version N9860
Haven't test on it via USB to PC

after update to android 11, the phone must connect usb-C to either pc or ear phone, then power n vol up.

I confirm last statement. I've updated to Android 11 and spent more than 20 minutes trying to go to both recovery and download mode. Only way i managed with by plugging in my earphones... thank you seanmcs

Didn't work for me in first place. holding power (bixby) + volume up just restarted my device. i connected the phone with PC and tried same thing and it worked.
I am using note 20 Ultra (Exynos version) with One UI 3.0

Have I just bricked my faithful A70?

So I tried to install TWRP and followed the steps, used ODIN v3.14, it tried to upload something but failed with an error.
Now the phone has gone into a perpetual restart cycle:
1) Reboot (by itself or Vol Down + Power)
2) Blank screen with: "Galaxy A70 - Secured by Knox - Powered by Android"
3) Screen with: "This phone's bootloader is unlocked and its software integrity... - Press power key to continue"
4) Blank screen with: "Galaxy A70 - Secured by Knox - Powered by Android"
5) Blank screen with: "SAMSUNG" for a very long time
6) eventually back to step 1
****************
Is there a way to get back this phone?

I was flashed twrp normally and nothing happened for me. Did you pressed vol up+power ASAP after flash successful ? If not, go to download mode and flash again, then press vol up+power immediately.

I never managed to flash TWRP, ODIN displayed an error when I tried.

1. Your using the wrong version of odin. You need 3.13.3
2. Sounds like your not key comboing fast enough?
3. You can not hard brick the A70. If its in a boot loop, plug into pc and Continue to hold vol up and down till it boots to download mode. Flash latest stock version then reboot.

Dont press power during the end process, its power and vol down till screen goes blank then immediately let go and press and hold just vol up.

OK, I am now in the "Downloading..." screen and the phone is waiting.
All I have on my PC is:
recovery.tar
twrp-3.6.1_9-0-a70q.img.tar

I do not have the Samsung firmware or anything else.
What should I do now?

Get frija from the link in my guide under tools, install it on your pc, then use it to download your latest stock firmware. Make sure you have odin 3.13.3 as well
In frija, enter the model number and the region code of the A70
In my case it would be SM-A705MN/ TTT
Do NOT flash other models, it must be for your Model. Also, dont flash csc_home in this instance, use csc. When loading the AP file, it will take a little bit to load in and you may see odin has stopped working, ignore that and it will eventually load, make sure auto reboot is unchecked everytime you use odin. The first step in my guide says to download and flash latest stock firmware. Anytime your going to do modifications to a device, make sure to have the latest stock firmware first.

Many thanks for suggestions.
I managed to download the stock firmware from https://www.sammobile.com/samsung/galaxy-a70/firmware/SM-A705FN/BTU/#SM-A705FN and have uploaded it using ODIN 3.14 The phone has now started, like new / factory reset.
I am now setting it up (Samsung firmware) just to make sure I have got my phone back.
After I will try to zap and upload another ROM.

I didn't said that hold power button during flash. Press vol up+power after successful flash, that means when odin say pass then phone goes black and boots, while bootsplash is coming, immediately press and hold vol up+power to switch to recovery.

In download mode, Android 11, to exit, it litterly tells you on the screen to hold vol down and power to reboot. Vol up and power does nothing in this state. To get to twrp from download mode, hold vol down and power till screen goes blank and then press and hold vol up. This will boot to twrp. Other ways to boot to twrp is power off device, plug into pc, wait for it to charge, then hild vol up and power till it boots or if magisk is installed, use magisk reboot options.
Dude, your key combos and information is incorrect. You can not reboot to twrp from download mode by holding vol up and power.

Samsung changed the keymap combination to boot into recovery on 3.1, so to boot into recovery stock or whatever it is, just follow the steps:
Connect your cellphone to the USB port.
Press on Volume UP during boot.
Samsung does weird things

My key combo is true, actually the wrong one is yours This is the valid way also on the latest bootloader but like haky86 said, on latest bootloader Samsung wants you to plug USB cable to do this.

So we are agreed, there is no way to get to TWRP unless you are connected to USB? For example, on my one old phone, I used to keep TWRP backups on the SD card, and I could restore anywhere, I did not need to be near the PC with a USB cable.
