SAMSUNG exhibit ii 4g restarted repeatedly

Hi would somebosy help me?
I just bought a SAMSUNG exhibit ii 4g,and rooted with the peach sunrise ROM, it works fine at my phone, but today I encounted a big proplem. it restarted repeatedly.
I tried to delete my old gmail accout and use the new one, the phone told me to restore to factory set, so I enter the settings/privacy and clicked the reset, but no response even after 5 minutes, showing up 'the reset is in progress', so I pressed the power button to enter the recovery , but at this time i did not find the ROM file, so I opted the reboot, then the phone began to restart repeatedly.
if I hold both the power button and volume down button, it show up" warning!! a custom OS can cause critical problems in phone and installed applications. if you want to down a custom OS, press the volume up key,otherwise press the volume down key to cancel", at this time,if I press down, the phone will restart repeatedly; if I press up, it shows up" Odin mode product name: SGH-T679 ; custom binary download: No; current kernel: unkown!! Downloading.... Do not turn off target" (I turned off the WiFi before I tried to restore to the factory set)
Help me, Thank you so much!

[Q] My new Samsung Galaxy 3 isnt working

Im new to all rooting and Recently i attempted to root my phone for the first time it using the Samsung galaxy s3 toolkit V5. My build was not listed so i selected build #1, I installed the drivers to my pc, went to rooting options, selected option #3 All In One, Enabled usb debugging ans started the process which opened up odin and started doing its thing, but basically my phone was in odin mode with the android figure which says downloading... Do not turn off target! but of course I thought it wasnt working and i had to unplug the usb and put it back in (Im such a noob).
Now my phone will not boot at all, when i hold up volume power and home a battery image shows up and the phone shuts off again even though its plugged into my computer.
When i hold volume down power and home, this shows up: Warning! A custom os can cause critical problems in phone and installed applications
if you want to download a custom os press the volume up key, otherwhise press volume down to restart phone.
If i press voulume down it does not restart, it simply shuts off again.
If i press volume up it goes back to the downloading android even though it isnt downloading anything.
At the top left corner it says:
ODIN MODE
Product name: SGH-I747M
CUSTOM BINARY DOWNLOAD: Yes (3 counts)
CURRENT BINARY: Custom
SYSTEM STATUS: Official
QUALCOMM SECUREBOOT: ENABLE
My phone is not even detected on my computer or by the toolkit anymore.
I cant find any solutions to my specific problem anywhere on the internet and im starting to lose hope. Please help me.

[Completed] Samsung Galaxy Grand Prime SM-G530H USB problem

Dear Sirs,
My mobile: Samsung Galaxy Grand Prime SM-G530H
I have problem with USB ADB showing mobile serial
but it is saying unauthorized device I tried the code *#7284# not working.
It is Rooted and I have Busy Box installed.
When I press Down + Home + Power it says Downloading ... Do Not Turn Off Target!!
I can not even make selection it stay long time like this.
Please Help
Thank You

Hello,
Welcome to XDA.
When you press and hold volume down+home+power and it gets to the caution screen, you press volume up to enter download mode, then it takes you to the "Do not turn off target" screen. This is download mode, it is used to flash the device with stock firmware and other files.
If you want to connect to adb you have to be in recovery mode(volume up+home+power) or you have to be booted into system.

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.

yeah I did that a lot of times, it used to work now It doesn't anymore
in this video you can see what's going on, I'm pressing both volume keys and nothing happens

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?

[NEED HELP] Bricked my phone with low chance of any recovery

I need help urgently. I tried to change the splash screen of my Samsung Galaxy A51. I downloaded a custom param tar file, placed it in my downloads folder and used this command in adb shell to replace the older one. I did back up my old param. But there's no way I can restore it. Now, my phone when I try to start it. It doesn't even seem to turn on the screen anymore. I hear the phone vibrating every 2 seconds so I assume it keeps rebooting. I tried to enter download mode but I can't because samsung made it that you need to go into the recovery first, so I tried to go into the recovery but nope, it keeps vibrating and it's not responding to whatever I do. Is there still any hope for my phone? Thanks in advance.

Hello, I had this problem too. My phone also stopped booting into anything, even in TWRP.
For me, the resolve was to make the phone force reboot by holding power button and volume down, then immediately try to enter the downloading mode by holding volume buttons, when the screen turns off

and then you need to flash your device with your stock ROM

I understand you, that you cannot enter the recovery, but for me this method worked

I managed to solve it, the problem I had was that I was unable to boot into download mode. Because I have a samsung galaxy a51 and I did not know how to enter it. The last phone I had was a samsung galaxy s7 edge, back in the old days it was easy to enter download mode, just hold volume down, power button and home button. Now for some reason I need a cable connected to my computer and then hold volume up and down simultaneously. After I figured out how to enter download mode I flashed stock rom and phone worked again.
