Help I think I've bricked!

I had been running cognition 2.2 beta1, put phone into download mode using vol up vol down and put in usb cord and flashed back to stock. Then I flashed Shep211's JPM\JI6 ROM via rom manager. Reflashed a JI6 kernel, then tried to use rom manager to flash to cognition 2.2 beta7. The update failed and now I only get the phone exclamation computer screen and I cannot get my phone back into download mode! I have tried almost every combination of vol up vol down power and usb I can think of to no avail. Can anyone at XDA help before I return the phone to ATT?
Any help is greatly appreciated!!

Pull battery. Just keep trying to get into dl mode. That's all I think you can do.

Have you tried doing it via the SDK? Really easy that way.

through ADB you mean?
I just get error - device not found whenever I try and run any adb command.

Yes, I had to do the "adb reboot download" with the SDK running.

can you be more specific? I can't get adb to recognize this phone in its current state.

1- Pull battery and USB cable out..
2- Press Vol Up while you connect your phone to the USB
3- Insert battery, and keep pressing Vol Up!!!
or
1- Pull battery and USB cable out..
2- Press Vol Down while you connect your phone to the USB
3- Insert battery, and keep pressing Vol Down!!!
or
1- Pull battery and USB cable out..
2- Press Vol Up while you connect your phone to the USB
3- Insert battery and, keep presing Vol Up, press the Power button..
Keep pressing Vol keys means that you must keep pressing the buttons until you get the Download Mode Screen.. And keep trying.. Sometimes it take some time to work..

What I did was download and install the SDK in the C:\Android directory
Then open a windows command prompt and navigate to the "Tools" directory
Then just run the adb command.
Not sure what to tell you if the phone isn't recognized, I'm pretty new at this myself. I'd start hitting Google.
Good luck.

You can go to Download mode from Recovery.. But not from the Phone+Computer screen.. I think..

Thanks for the suggestions, I tried these all several times, waiting about 1 minute before I gave up each time. Should I wait longer, or do you have any other suggestions? I'm about ready to give up and make a trip to AT&T

I've tried all of the suggestions in this thread already, I have somehow managed to completely brick this thing. Thanks for all of your help!

If you were going to Cog 2.2.7, why wouldn't you just have wiped, flashed to stock, rooted and then flashed with Clockwork Recovery?
Anyway, good luck.

-Did you try to start pressing the Vol button AFTER you plug the USB cable? And before you plug it?
-Did you try another USB port or another PC?

Here is the Fix
I was in this same situation last week. Here is how to get it back into download mode.
•Be sure the Samsung USB drivers for the phone are installed on your computer.
•Remove and replace the battery.
•Connect the phone to the computer with the USB cable. The "phone-exclamation mark-computer" picture should display on the phone's screen.
•Hold the Volume Up+Volume Down+Power buttons down simultaneously.The screen should go blank, then the picture should appear again. When the screen goes blank a second time, release the Power button while continuing to hold the Volume Up+Volume Down buttons down

This is the only method that consistently works for me. I use the exact same method. The key is whatever picture (att, battery charge, etc....) comes up the second time and then goes blank, then release the power button.

[Q] How to boot into recovery without ROM or power button

My Galaxy S3 just faced the bootloop issue because of a faulty power button. I had CM12 installed, so couldn't use warranty. I opened up the phone, and cut the power switch off with a razor blade. Now, I can boot to download mode using the volume and home buttons while plugged in, and cancel download mode to boot phone. My issue is that I experienced a huge battery drain on a ROM, and dirty-flashed another ROM over it. Now, the phone won't boot. I'd like to go back to CM11, but can't figure out how to boot to recovery. Thus, this is what I need:
A way get to recovery, without using a power button, or booting up the phone

If you can boot to download mode, you can get to recovery mode. Here's how. I figured this out when my power button broke and I removed the power switch from the phone's motherboard, so it should work for you:
1. Take the battery out of the phone and unplug it from USB power.
2. Plug in USB power.
3. While holding down the volume-down button and the Home button, insert the battery (this is a little tricky).
4. The phone should start and warn you that you are entering Download mode.
5. Press Volume Down to reboot and then *immediately* push and hold Volume Up and Home simultaneously. The phone should reboot into recovery. Mine does.

Yes - thank you very much! FYI - when I read @Jacquestrapp 's instructions, I suspected the battery gymnastics wouldn't be needed since I had already learned (in this informative video) that I could boot the phone from a powered-off state WITH THE BATTERY INSTALLED by plugging in USB power and immediately depressing home and vol-down. This gets you to step #4 above, and proceed from there.
So this is cool! My trusty-old d2vzw's power button had stuck in the "On" position last September as they apparently tend to do, so I set it aside as a brick and bought a used HTC One m7. Needing a WiFi skype device for a friend, I searched and read about scraping off the S3's power button and operating without one. Now, I see how much I missed the S3's AMOLED display colors and contrast compared to the 1080p display on the m7, and I'm reluctant to part with the S3 .

Help - when pressing volume down it does not reboot.
I9300. could there be a difference in different regions?
edit: volume down switch (not the plastic bit, the hardware connectors) was a bit flimsy so I had it replaced. Still not working though.

I read the instructions wrong. I was using a USB jig to directly boot into download mode. But I need to get to the prompt before it. However, when following the steps the phone just begins charging instead.

Boot the phone, when it gets to the unlock screen try connecting it to PC and open an adb terminal then type:
adb devices(press enter, if it returns a serial number your device is recognized)
Then type:
adb reboot recovery
Or
adb reboot bootloader
Try unlocking it and typing the reboot commands while it is frozen.
Or you can order a USB jig for $5 US or less from eBay.
Or you can use an old USB cord and a 300k resistor(or any combination of resistors equaling no more and no less than 300k) to make your own jig, there are videos on YouTube for making your own jig.

I don't know if you are been cheeky or not, but I will go check if I can actually touch the option. Lol.
In case I can't what ROM can I install via Odin that will give me touch recovery. Or what other options do I have?
I really don't want to take it apart again to remove the plastic button so I can short the power leads with a wire to mimic a power button press.

You need to be in a mode where the kernel can activate charging mode.
Try booting to the download mode confirmation screen, but don't press up to go to actual download mode.

Considering I have seen these same symptoms now on several devices included the J4+ I would be pretty certain this is a totally flat battery.
The fact that you say it boots to recovery simply suggests pilot error and not actually booting to download mode. It will continue this loop until you actually boot to download mode.
You need to have the USB cable attached and then firmly hold Power + vol down + vol up until download mode appears. Ensure both vol down and up are firmly pressed.
If it flashes recovery then simply continue to hold the 3 buttons above.

I'm sorry but the way you are holding all three buttons does not ensure all buttons are correctly pressed.
I suggest holding down and power with opposing finger and thumb and up with the other finger of the other hand.
Also ensure the cable is attached to the PC. It's also worth trying a different cable.

Does your PC have the Samsung USB drivers installed?
I can't understand why it's not activating download mode.
Booting continually to recovery is a function of a bootloader flag which has been set and not cleared.
However power, vol down and up bypasses this flag and forces the bootloader to boot to download mode, so I'm a little perplexed as to why it's not working.
Might be worth leaving it bootlooping until it completely switches off and then try and boot to download mode from an off state.

Download mode is different from fatboot mode, I can enter, and works ok download mode. However, fastboot does not, it gets stuck in entering fastboot mode and no fastboot command works

I got same issue here, I've tried rooting via TWRP and after data wipe and "reboot to recovery" it got stuck in same thing and doesn't move at all, if I hold power and vol down it just boots the device which i dont want since i need to flash magisk as a last step. if anyone encountered this or knows how to fix it i'd be helpful

I'm not rooted but I've had past Samsung devices that I was able to root and if I'm not mistaken Samsung phones aren't able to boot into fastboot mode because Samsung removed the ability to. You can run commands via ADB mode but I think that's about it

Since we can"t enter into fastboot mode is it possible to flash boot.img with adb commands?

I m having the same problem with a21s(a217f). I can t enter download mode using key combinations and the other way launching it from recovery doesn t work, it stays stuck at,, entering fastboot mode,,
The ROM is already bricked, it says in recovery when i try to factory reset the following error:,, can t mount. /system (structure needs cleaning)
Even with,, apply up. with adb,, doesn t work, it just doesn t get detected on my computer when i checked with adb tools.
! The only thing that works is that I can access my sd card and apply a update from sd card but I don t know where to get the update file. (I ll edit if it works to flash stock rom from,, apply update from sd card,, )
Anybody got some ideas or should i burn my motherboard and replace it?
sorry for bad english

Honestly plug device into PC.
Power off device
hold all 3 side buttons. Volume up and down and power/bixby.
Should usually work.
After in fast boot you must press a button Volume button to find via odin.

It wouldn't be deleted as it's a safety protocol if the device has a bad update and freaks out.
Maybe try to person above method.
Normally I can enter download mode with any of these methods if you cannot I'd suggest trying to get the device replaced due to software malfunction

Samsung phones use a tool called Odin to flash firmware. If you're flashing custom firmware firmware you'll need to have your bootloader unlocked.

I got mine into download mode just now. It's a Galaxy A13 .. Like stated above, try to hold all three buttons down and connect to USB. I had to let go before it showed the battery charge icon. From off. If not from off try from charging. I think that's what I did just now. Plug the usb -> let it show the charging icon (from powered off!) -> hold all three buttons, let it power on, let go. DONE.

just follow this video it helped me a lot to unlock my boot loader

Question my Galaxy A12 won't boot to android or download mode help me pls

so I just tried to install unofficial TWRP 3.5.0 on my Samsung galaxy a125m and everything went fine, Odin said done. Then I just tried to start TWRP by pressing power and vol up and it didn't start, so I thought I might have done something wrong and rebooted to download mode and flashed it again, Odin said done, then I unplugged the USB cable and now it won't boot, neither to the system or recovery, even to download mode, it did enter download mode a few times before but I pressed the wrong button and had to cancel and enter again, now it won't even enter download mode so I can't flash stock rom to fix bootloop... pls how can I solve this I'm desperate
when I try to enter download mode by pressing volume up + volume down it just shows up charging mode without any numbers, then it turn on and shows Samsung logo, unlocked bootloader warning screen, and the Samsung logo again, but then just restarts and repeats all again...
when I try to press volume up + volume down + power, nothing really happens...
someone help me please

You need to keep both volume up and down pressed, then plug in the charging cable. It should enter download mode, no need to press the power button like in older samsungs.

Is the cable plugged into a charger and on?
Have you considered that your volume buttons may not be working?

Same hear

Try attaching your phone to the PC, and then pressing volume down + power to reset the phone, (for about 7~8 seconds) then immediately press the volume down and up buttons, that's how I recovered from it. Tell me if it worked

Please help it dosent worked

Hello, unfortunately in these cases the only solution is to enter download mode, check if any button is damaged or if the cable works and if it is well connected, press the buttons harder, hold down the volume up and volume down buttons at the same time , by pressing the strong buttons, for about 6 seconds and then connect the cable. If you don't try another cable to see if that's the problem there is no other solution as the phone is not recognized by an app that can put it into download mode when turned off the solution is the one I already told you about. I hope you have fixed that problem. Sorry for my bad English.

I am having a similar problem with the Samsung A12 SM-a125u
I never could enter into this "Downloading mode".
I tried flashing the stock ROM through ADB with fastboot, and I have another problem that I've never seen before: ADB can see the device while in recovery mode, but fastboot can't. And so it won't allow me to flash the ROM and I don't even know how Odin is supposed to help yet; I think I needed to enter Downloading mode for that, but I can't get into it.
I'm working on this phone for a friend who was given it because his friend's mom doesn't remember the password to it. Does that matter? It's worth noting that because of that I cannot get in to turn on OEM unlocking or dev mode, but idk why that would come into play in recovery mode. Also, the model indicates this is an AT&T phone, and tutorials online have acknowledged this model in their "applicable models" list at the beginning of their tutorials, but I know that carrier phones can cause problems all over the place (stop buying carrier locked phones people!); is this a problem?
How the heck do I flash the stock ROM to this this?
