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?

I want to flash a custom rom and root the device as well

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] Tab Pro 8.4 won't turn on

Hello everyone! My Galaxy Tab Pro 8.4 won't turn on anymore. I tried charging it, that wasn't the issue. I left it on the charger and nothing changed. I plugged it into my PC and it didn't make any noises and it doesn't even recognize it as an unrecognizable device. Is there any button combo to see if it's 100% fried or not?
A couple of weeks ago I rooted it and updated it to another ROM, but it had been working PERFECTLY since then! WEEKS!
Any suggestions?

power button
Press and hold the power button for 30 - 40 seconds and see if it powers up. I had this problem yesterday.

This did not work

Hold the power button down for 2 minutes and don't let go, also hold vol up while doing it to see if you can get into recovery.
keep it plugged into the charger while you do this.

OK, this worked. How can I unroot and restore the OEM bootloader and everything?
Before flashing I made a TWRP Backup, as well as a Flashify-backup.
I have these two folders on my desktop.

to restore everything you will need to boot into download mode , if you are in download mode now you can use kies or odin to flash the stock firmware and this will correct everything.
to boot to download mode its either (Power + vol down) , or (power + vol up) , try both until you see it say download mode., or if you are currently in twrp you can select reboot->download mode
you can get th stock firmware here

v500 Stuck Bootlooping - Cant Access TWRP

Hi all,
Have a brand new (to me) v500 that i bought and was able to root, flash twrp, and flash crdroid on yesterday. Today i flashed standard AOSP but now i'm stuck in a bootloop and cant figure out how to access twrp any more. Previously with crdroid on it i was accessing the bootloader/twrp via an app. So far all i can get to come up using hardware buttons is the download mode, and ADB isn't recognizing the device.
Any advice? I tried following a guide to revert to stock using the LG Support Tool but cant find the R&D tools to complete the tutorial.
Any help is appreciated.

Bump - $10 USD to whoever can help me solve this first

To enter twrp via buttons on v500:
Press and hold Power Button + Volume Down
When the LG logo shows up, release the power button only
Now press and hold the Power and Volume Up button while keeping your hold on the Volume Down button
When the factory reset screen appears, release your hold on all buttons
Follow On Screen Indications to make factory reset, but instead you enter twrp

Using that combination of buttons doesnt bring up any menus, i see the LG logo and then either holding the power button shuts down the tablet or it tries booting into Android, which then loops.

b0li gave an invalid TWRP entry instruction.
Read How to enter recovery mode using key combination post #2.
In TWRP, do advanced wipe without internal storage.
Before you flash the ROM, check its checksum carefully to see if it is identical to the one on the server.

I tried the corrected key combination, but no menus pop up, I either hold the power and vol up/down buttons until the device turns itself off, or it boots to the Android logo and then loops.

It turns off because you hold 3 keys and don't release them.
You must press them simultaneously and then release them immediately.

That did the trick, can't believe it was just because i wasn't pressing the keys exactly right. I was able to get back into TWRP and reflash the ROM so now everything is working. Still having trouble getting usb to recognize the device, so i can't flash anything else on there at the moment.
PM me your paypal or venmo

Perhaps the problem is not the usb socket or cable.
Blow out the socket with compressed air and try again.
If that doesn't work, then your OS may be a problem.
In this case, try [LIVE-ISO][FWUL]adb/fastboot without any installation and driver issues.

I tried another computer too, same result - the tablet recognizes the connection so it starts charging, and despite the USB settings in dev options being set for MTP, it doesn't connect.
I'll try your link later, but it seems like its a problem with the tablet compared to computer.

You can always transfer data using microSD or via WiFi tethering.
If via WiFi, I recommend the SwiFTP server - simple and reliable.

I tried to update Lineage and am running into an issue now where as soon as the LG logo pops up, a message that says "Secure booting error! Cause: boot certification verify" pops up almost immediately so I can't use the hardware buttons to get into TWRP. Any ideas around this one? Thanks again all!

Bricked Phone

Hello, I have the A705FN/DS and I tried do Custom Recovery and ROOT but i'm suck on this screen ( https://imgur.com/lVOX4rt ), i can't boot in recovery or download mode, i can't use the phone, Someone can help me?! Already tried a lot of things on internet but nothing so far..

Try not to panic, I've seen this several times.
- Plug the charger cable into the phone.
- Press and hold all three buttons (up volume/ down volume / power) at the same time and keep holding them, wait (at least 10 seconds+), phone will reboot (keep holding all three buttons and wait), even if it says 'press power button to continue, wait), hold the buttons and wait. It may reboot again....
- Keep holding the buttons until the screen goes black then release all 3, this should take you to a blue screen, slightly different blue to the normal download screen, with 3 options:
1. Press the up button once and quickly to download a customer OS. <- Select this option.
2. Long press the up button to go in device bootlock mode.
3. Press 3 to restart.
Start ODIN and download/flash stock firmware for your phone.
If you do get to download mode, be sure to uncheck 'reboot automatically' in Odin, just in case you have some failures, you can click on the 'Reboot to download' in Odin without have to fuss about with all the button all the time.
You must reboot to download mode EVERY time a failure happens before trying to flash again, else you'll need to do the 3 finger thing all over again.....
Worked for me! :good:
Might take a few attempts to get to the download mode, but you should be able to recover it, no worries (had this last night).
Update if it works!

i installed trwp successfully. After that i decided to flash havok os. After that phone went into bootloop. It loads only to twrp and stacks on twrp logo screen(with its build number) no reaction on buttons. Any chances to do something with Odin?

First, make sure that you've the latest official firmware is downloaded on your computer. Then, prepare your phone's cable by connecting it's one end to the computer, keep the phone disconnected for now.
Open odin, prepare all the official firmware's files including ap, bl, csc etc. All of them. And make sure that you've selected the CSC file, NOT the HomeCSC..
Now, you should read this paragraph completely before taking action. First take yor phone and put you fingers over the volume buttons (both of them, up and down) and the power button. Wait until screen turns off (as you said, it was stucked on TWRP). Once it turns of and it's black, dont waste so much time and connect the other end of the cable to your phone and wait till a blue screen shows up.
Now, if the screen is showing you options like Download Mode or Bootloader Unlocking, tap to volume up to enter download mode. If it's not showing you options and it is showing a warning screen like the screen mentioned in the first entry up here, it's ok, you're in download mode.
Start the proccess with odin. Then tell me the result. If it stucks at the end of the 'SYSTEM' installing, tell me that before waiting longer than 10 minutes after all the sign of life dissapears in odin. Waiting for your respond ^^

Thank you very much! I will try that asap, since the official firmware still downloads(probably several hours). I just recorded a video of how things look right now.

Ok, tbh you're phone is in a nice condition. You can relax if you're not. Several hours? This seems long, if it is not about your network speed, I mean if you're installing the firmware from a website please try to install it via frija instead. You can find it here.: https://forum.xda-developers.com/galaxy-a70/how-to/galaxy-a70-firmware-list-variants-t3957239
And, please be sure that you're installing the right firmware for your model.
The only thing you should do is pressing all the buttons simultaneously and connect the phone to the computer while the phone's screen is off. Then enter the download mode.

Oh yes! Thank you, sir! i got to that blue screen.

I'm using the Samsung Galaxy A70 (SM-A705MN/DS) on T-Mobile. Got it on Amazon.
Came with case, earbuds, and 128G SD card, but only a USB-C to USB-C for charging. You'll need a different cable if you plan on rooting.
My post about it:

EdXposed Installer 2.2.5
Riru Core 19.5
Riru - EdXposed v0.4.5.1_beta (4463) (SandHook)

did you unlock bootloader on youres? and the usb-C cable it comes with doesnt work if you want to root? is there a special type c or just another one? because i have a type C cable

Why only flashing ap? Flash all the files. Csc And Home_csc has a difference. if you flash csc, your data will be formatted. If you want to keep your data, flash home_csc. Dont flash only ap. How did you try to enter twrp? did you try to flash ap over a phone with custom recovery? Flash all the files. Hope you backed up your data. Try to flash all files with home csc, not only csc. if doesnt work, flash all the files but with csc this time.
To enter download mode, be sure that your phone's screen is black and connect the phone to pc at the same time you press all the buttons.

Just upgraded to latest Magisk from the App, now stuck at boot screen HELP!

I have already tried key combinations, but still the same.

@hainguyenthao helped me out. Showed me how to get into downlaod mode without pressing power and vol down!
Let the phone power down, leave it for 30 mins or so. then press vol up and vol down and insert USB cable.
OR if phone is in bootloop, press vol down and power till phone reboots, then VERY quickly hold down vol up and vol down and plug in USB cable

Dude, To put device in download mode - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable.
But for your problem you have to put your device in recovery mode then flash ROM. Still the problem continues, you can try this download link

I've the same problem with my Note 10+... Was on Dr. Ketan Rom and update with magisk app ends in a boot loop, I couldn't break -.-
@vinokirk could you solve the problem?
Edit: Thanks to @starpandi2004 - on the first try I can break the bootloop, but just to the first screen. After choosing download mode, it comes bootloop again -.-
Is it worth to try to lock bootloader and factory reset phone? What will happen? Is the original rom somewhere packed and would be installed again by factory reset?

Bro what about TWRP recovery? can you able access it...
if yes then dirty flash KETAN ROM..it will solve...

just had same same problem.
i connected mine to the pc and use power+up volume until twrp appeear and them restores from last backup

I got the simplest solution for this issue!
If u r stuck on Samsung logo, then try this method.
Turn off the phone by pressing vol down and power button. Once the phone is shut down, release and press again the vol down and power button when u see Samsung note 10 plus screen, then release the power button but keep pressing vol down. Once u see the "Samsung" logo, immediately release the vol down button and quickly press vol up button.
This will boot up without any problem!
