Hi,
Recently i was trying to apply another rom to my Samsung Galaxy A7 2018 edition and i am stuck in an infinite bootloop. I cannot enter download mode with the Volume Down and Power keys and the only thing it does is showing the logo of Samsung every 5 seconds and restarts. I have tried to built a usb jig with 300k resistors and still does not boot up in download mode to flash with odin a stock firmware. Also i left the battery to drain and now it is turned off,but when i plug in the usb cable and power it up it still goes into infinite loop. Any help?
I was trying the Android 10 Magisk root for A750F and was greeted by a similar situation after ODIN rebooted my phone after flashing Magisk image.. Anyways, don't panic, try all combination of buttons. vUP,vDN,PWR or vUP,PWR or vUP,vDWN while connected to usb.. It wasn't working for me too but i tried all combinations and it landed me to download mode where I flashed the stock rom
just press those button and connect to usb
im glad i read his, had just the same issue while flashing wrong twrp on A750FN .. yihey thx budies
how did you solve this issue.
---------- Post added at 06:54 AM ---------- Previous post was at 06:45 AM ----------
which button combination helped you. I having a similar issue. can not enter download mode.
Solution that helped me
Just Press the volume plus + volume minus + power button at once. Once the phone reboot black screen appears, Leave the power button and keep pressing the volume plus and volume minus button. It will redirect to the download mode. and reflash the room using Odin. Only use official sammobile rom file as other files may be corrupted. The issue may arise. The problem is in rom.
If any issue query me at : [email protected].

I have tried keeping all 3 buttons (vol up + vol down + power), tried holding vol up + vol down and then connecting to my PC (nothing happens, I always see the same screen (SAMSUNG Galaxy A7 Secured by Knox and Powered by android underneath)).
Tried vUP,vDN,PWR or vUP,PWR or vUP,vDWN while connected to PC via USB.
Tried vUP,vDN,PWR or vUP,PWR or vUP,vDWN while NOT connected to PC via USB.
Phone sometimes reboots but always gets into the screen I mentioned above.
Odin, obviously, doesn't see the phone either.
Also, adb devices command deosn't show the device in the list.
Anything else I should try?
Ah I solved it, and nobody mentions that you have to be SUPER quick!?
So you hold down vol down + power button and keep the USB cable at hand and the millisecond your phone reboots, reeeealy quickly release vol down and power and quickly afterwards press vol down + vol up and again quickly plug in your USB cable, if you did it before the Samsung logo appears you will get into Downloading... screen.

Ok. I bought this Galaxy Tab 2 7.0 from a friend for cheap because I thought I could fix it, but I'm running out of options. It's in a boot loop, but an abnormal boot loop. If it's unplugged, It will do the splash screen (Samsung) boot loop. If it's plugged in, either into the wall or into my computer via usb, it will do a battery (charging) boot loop. It's kinda weird. I used to have an Epic 4G and it happened damn near all the time, without the battery loop, but it would charge normally.
I haven't successfully gotten it to boot into Download mode.
If any of you have come across this issue, please feel free to help me out.
I also attached a picture of me attempting to put it in download mode. It reboots if I hit either VOL up or VOL down.
Thanks

Can you get into recovery? Also, have you tried unplugging the charging cable and getting into download mode with the cable unplugged?
I'm not sure how to get into recovery. With it unplugged, all I have to do hold the VOL Down physical button and ti will take me to a "are you sure you want to put the device into download mode screen". I apologize. I'm not to familiar with this device.
Edit: After I get to the screen where it asks me if i want to go into download mode, it reboots within 5-10 seconds, no matter which button I press

Hold power and Volume up (volume button closest to the power button) until the tab shuts off and reboots itself and then you can let go of both buttons. If it works, try doing a factory reset. Was this tablet rooted (or have a custom rom installed) in the past?

As far as I know it's been on Stock. My GTab ignores me holding the Power and Volume up keys at the same time and keeps the boot loop going strong.

Then I guess you can (and need) to send it in for warranty service (or replacement).

No, his device is fine.
If your device bricked, but still showing Gtab2 logo on it, it's still fine. You need to flash to stock 4.03 rom via ODIN. (Not clockworkmod)
Warranty won't work if you have flashed custom ROM before.

He needs to be able to get into Download Mode to use Odin. He stated that he can't. When he tried to continue into download mode by pressing volume up (vol. button closes to power button) the tablet reboots. It needs warranty service.
Experiments:
Power off the tab completely and charge completely and press power +volume up for 10 seconds then release, also try to power off and press power+ volume down for 10 seconds then release do you see any screens
If it says do you want to enter download mode or so press volume up and see if you could see (downloading) try also the same with volume down instead of up
Try to connect to computer do you see any messages indicating connections
Also try to connect to kies and try restore or recover firmware from options of kies
You said it reboots after 5 to 10 seconds so try to open odin and try to go to download mode and when you press volume up try as quickly as possible to connect tab to pc while odin is open

There's other method by using OpenRecovery (OR), by putting OR on external SdCard,
but it seems the OR for Gtab2 is not developed yet -__-
Hello,
I have a problem, today I install the combination file to my SM-J410F Samsung device but it not work I get %80 and failed and write something (like custom binary fused ) but after that I want to download another Stock firmware but I noticed that it cannot into download mode and when I Press Vol up + power it only show the Samsung logo and turn off, I try many times but it's something.....
I also use jig USB to force the device to download mode but it doesn't work.
Please help me it's very important to me. I Appropriate your bits of help.
Hi,
I have J415 in hand and I believe you can follow these steps:
1. turn off the phone
2. hold vol up+ vol down and connect usb
you should be in download mode now.

Recovery
Plz i want link to twrp (recovery) of samsung j4 core (SM-J410f/ds)
I also have a this issue. Power & vol+ & vol- plug in USB, Samsung logo then a blue screen, possibly with an exclamation mark, but only for a split second. The reboots and does the same continuously. I was on android pie uk and tried to flash twrp, failed 3 times. Tried to reflash 8.1 which ended in a fail and now it won't boot, won't boot recovery and won't go into download mode. Does this mean a flat battery? Should I leave it on charge with no sign it's charging? Hold the 3 buttons on reboot for 5/10 minutes?
As it stands now, it's not bricked but I can't do anything with it.
I solved it by holding all 3 buttons and plugging into USB, it did the whole rebooting thing as usual but I kept the buttons held for about 15/20 reboots and then it FINALLY went into download and I could flash stock rom. If important or not, I'd left it charging all night but showed no sign of life whilst it 'charged'
have same problem same it is kind of security to avoid writing Combination

You are hardware bricked, your Samsung has a hardware component that, once tripped, will not let the device boot.
You tripped the "fuse" by attempting to flash TWRP or some other custom software not approved by your manufacturer or carrier.
Next time, do better research before attempting to modify your device.

Its volume down+home+power if the device has a home button.
Or volume down+power if the device does not have a home button.
Or a USB jig
If none of these work to get the device booted into download mode, the only options left are a JTAG/Riff/Octobox service or replace the motherboard.

Just flash stock rom with odin, conect to pc pressing vol + and vol - to get download mode
It doesn't react with + - buttons, that is why i can't flash it
What is the last OS you are running?
If the phone keeps restarting, first connect the phone to your PC via USB cable.
Then
1. Keep Vol+ and POWER pressed.
or
2. Keep Vol- and POWER Pressed.
Thank you but it seems that my motherboard is damaged

I do not think it has been damaged, try pressing vol + vol- boot at the same time a couple of times and then the third release the vol + i the boot and it will restart in dowload mode. then flash with odin each of the partitions of an original rom.
good luck

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.

in this video you can see what's going on, I'm pressing both volume keys and nothing happens
Your browser is not able to display this video.
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
No pc detection
No download mode
No recovery
No charging
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?
