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

this is my second time being stuck at this screen, but I'm having absolutely no luck this time around (have been trying for about an hour now). I guess I'll be making that trip to att.

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.

Hi
I've made a bad mistake which I'm hoping people can help me with. I tried updating my phone wit MIUI 8 as I had an issue with my battery. My updater app on my phone was not working so I downloaded zip file and tried doing it manually from the app. Then my phone just turned off and I'm unable to turn on or charge. None of the button combinations work and when I plug in to my laptop through usb port I get a message saying it doesn't recognise device. I've tried using unlock function on website but get error messages in chinese around ip address to malfunctioned phone number so no luck there.
Appreciate any help as I had a lot of information, apps and data that i would hate to lose. I lost my wife 3 months ago and I have some precious memories on that phone. I know I should have done a backup beforehand and that was stupid of me.
Is there anyway i get can my back in without losing data. if not then anyway at all to get my phone working.
Thanks, from a very down MI4C user
Try holding one of the power buttons(don't remember which one) and plug in the cable so the phone boots into fastboot mode. If you manage to get into fastboot boot TWRP and copy your files straight from it as it has mtp support. If your PC sees your phone as an unrecognizable device there's a big chance you can recover your data. Last hope would be to use a modified usb cable for edl flashing although this way you'll most likely lose your data.

Thanks, first suggestion doesn't work unfortunately. I have now been given permission to unlock bootloader but problem is the device is not recgonised due to usb issue.
So I cant turn on, won't charge etc and none of button combinations work. Has anyone encountered the issue with usb before. Unsure of 'modified usb cable for edl flashing'. All very frustrating.
thanks for any help
Anyone else have any ideas. Desperate here without my phone and important data
Have tried everything at this stage...utter despair. My phone just won't turn on or charge or enter fastboot mode etc
Anyone please help
The modified USB cable that I spoke of is used to force boot the phone into emergency download mode. It's baisicly a last hope flashing method that should work regardless of how broken the phone is. The only downside is that using this mode you only can flash via miflash and this will wipe your data. As for the cable you can either make one (look for deep flash USB cable schematic, it involves swapping 2 wires) or just buy one. Once you get into edl just follow the unofficial bootloader unlock guide to flash the 6.1.7 rom as it is flashed in the emergency mode.
Edit: whenever you plug your phone into your PC does the screen or led diode light up at all? You can also try holding vol- and power button and plug the phone into a charger (not PC) to see if it will respond at all. Charger gives more current so maybe it will force the phone to boot.

Thanks Adi. I don't think I will be able to make one. I've seen some threads elsewhere about getting into EDL mode, do you always require modified cable to do so?
Nohting happens when I plug it into PC, no lights etc. Tried charging using normal power supply but nothing happens either. Have even tried connecting to powerbank overnight but no power is taken from it.

So there is no "unrecognized device" popping up in windows anymore?
If so, let the phone lie for 1 more day (without connecting any power sources to it). Afterwards charge it (with a normal charger and a cable that works for another phone) for about 2 days (or until you see the notification led charging). if nothing happens you can try a different charger or an usb port for another 2 days.
If your computer recognizes the device ("unrecognized device" or just any reaction by connecting the phone) try to reinstall all the drivers (xiaomis/qualcoms, as well as adb, fastboot) and see if there is something happening.
Report back if it helped.
Edit: Did you try different cables? had similar problems with op2 (not recognizing) with xiaomi cable...
Edit2: to make sure the device is completely dead, use a linux distro (e.g. Ubuntu, ensures that there are no driver problems, you can install it on a usb drive) and a cable which surely works (try it on at least 2 other phones, if data transfer works its ok) then first install fastboot (ctrl+t to open a terminal) by copy/pasting "sudo apt-get install android-tools-adb android-tools-fastboot". Afterwards hold vol- and power button for at least 12secs and plug mi4c in (release the buttons after plugging it in). Now you can run "sudo fastboot devices" and see if there is sth listed (should even recognize it in edl).

You don't need to use the modified cable as you can enter edl from fastboot, but the cable method is used to force the phone into it if you can't enter it the normal way. As for rescuing it, try the method @wertus33333 suggested.

Apologies for not updating, I got an answer on MIUI official forum from a very helpful member called Codex. Below are steps he asked me to follow and although it took a few attempts my phone came back to life after following below and then pressing power and volume down for numerous minutes.

Download ROM flashing Tool http://en.miui.com/a-234.html
Then download fastboot rom, if you don't have previously downloaded one. http://en.miui.com/a-234.html
extract the fastboot ROM
Select extract location in flashing tool
connect your phone

Hello everyone,
I was trying to flash a firmware into my Samsung Galaxy J4+ (SM-J415FN) using Odin3. While the Odin3 was flashing the firmware, electricity got cut off and the PC went off.
The phone showed a screen: "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC Software".
When the electricity came back on, I connected my phone to the PC, and the phone started boot looping in the same screen. When I remove the plug, it stays off. Once I reconnect the plug, it starts boot looping. If I press POWER DOWN + UP at the same time while it is turning on (in order to go to DOWNLOAD MODE), it works, but once I press the VOLUME UP to CONTINUE, it shows the DOWNLOAD screen, stay there for a couple seconds, and then start looping again.
What can I do? Please, I really need to solve this.

Not necessary.
The battery has become depleted.
Boot to the download mode confirmation screen with the USB cable attached to PC. Do NOT select up to go to DOWNLOAD mode.
Leave in this state for a good few hours, may even need overnight.
This is to get some charge into the device, albeit slowly.
After a few hours try and swap to the mains charger. Hopefully the device will not turn off. If it stays on leave the mains charger connected for a while then press up to go to DOWNLOAD mode.

Hi, i've fixed this charging the phone not in confirmation screen but in the screen with serial number and imei (volume up+volume down+power button, and plug the usb cable, then release the button slowly)
If the phone reboots release the volume up first, then the volume down and then the power button.
Now you leave it charging and then reboot in download mode and flash rom with odin.
Let me know if you fixed it!

If i plug it in pc, got bootloop in confirmation screen, enter download mode, imei screen.
Last hope is plug it in charger, press Vol Up + Vol Down + Plug cable to charger (i leave it in confirmation screen don't press Vol Up or Down).
After an hours i take it out and plug it in pc, press Vol Up to enter Download mode and voila it didn't reboot so i just flash it with Odin.
I'm in bootloop as well, and for some reason, even when on 'enter download mode' confirmation page, the device turns off 30secs later. Same behaviour when I go on the page with IMEI, but there the device stays powered on longer (a minute or so). All while the device is plugged into my PC. Any help?
Hi,

as soon as the logo appears) but it doesn't work...
Anyone having the same trouble ?
Kind regards,

Try volume up (+) & the power button.....
I already tried that too, doesn't work either...
In the good old days, you used to have to have a usb plugged in to access recovery (and at one point actually also be in a recovery programme on a pc, or use a hacked together usb jig to do it on the fly). I would be surprised if they have gone back to that, but might be worth a try?
Turn device off,
Ensure one end of your USB Cable is plugged into the PC / Laptop
Press Power + Volume up
While you press both Power and Volume up insert the USB Cable into the phone.
Keep pressed and you should enter into the recovery, You used to be able to do this without the USB Cable, but recent changes made you require to plug it into a device.
Unsure if you can do this using a normal wall plug, i have never tried it.

Maybe it's an Exynos issue, I just booted into recovery with the volume up & power button combination (no plug-in of cord needed) on my Snapdragon-powered S22 Ultra.

Hi All, - I had the same problem, it would just not go into recovery mode. however a slight twist i saw on a website says to do the following and it worked first time much to my suprise..
basically the phone has to be powered on to start the process..
1.HardReset.info: At first, connect the device with the computer by the USB Type C and push Volume Down + Power button to switch off your phone.
2.HardReset.info: Then press Volume Up and Power key for a short while.
3.HardReset.info: Let go of all buttons if you see the SAMSUNG logo
4.HardReset.info: Now use Volume keys to select Wipe cache partition and confirm with the Power button.
5.HardReset.info: In the next step go to Yes option.
6.HardReset.info: At last, choose Reboot system now by using the Power button.
good luck..

Hello.
That only works with the included USB Type - C cable. It doesn't work with a USB type A cable. Both ends should be Type C.
That's why it didn't work for me earlier. I tried numerous times using the old cable from my Galaxy Note 9.

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

No pc detection

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?
