Samsung Galaxy A3 (SM-A320FL) can't enter download mode

Hi Guys,
I have a problem with a Galaxy A3 Model 2017 (SM-A320FL).
The phone has been FRP locked after a wipe.
Problem is, my documentation for the google account is wrong. So I cannot login into the phone again.
I tried several things but nothing worked. The only way to reset it would be sending it to Samsung (with my receip of purchase) who will carge around 100$ for revival.
One thing that is really strange : I cannot enter "Download mode".
Not via the buttons. (Vol-Down + Menu + Power) . It will enter a boot-loop after the "Samsung Galaxy A3" screen.
Not via the software tool. (Samsung 300K Tool)
Maybe someone of you has a idea how to proceed. Any help would be greatly appreciated.
Regards
McBlack

Hi I have no idea about that 300k software tool but I googled it to see what is was. I guess it simulates the 300k usb-jig (hardware). I got one of those and they work.
One thing , for that tool it's written :
Code:
Only connect USB Cable to phone ON!
- Android
- Bada
- Qualcomm Cpu
- Broadcom Cpu
You have an Exynos devices, so I guess it won't work.
Another thing, You mensioned that it goes to bootlogo when you try entering download mode. They usually never do that. They boot straight to the varning screen, without logo first.

If you do get it to boot to download mode, send me a PM if you want. I think I may be able to help you with the rest.

Bricked Honor 8 Pro - Error 11 (recovery image) and Error 2 (Load failed)

Well I screwed up.
I was having issues flashing TRWP and someone from Reddit had offered to help me. I was following his direct instructions which led to the phone being bricked and him blocking me....b******d....
What happened?
When flashing TWRP and going straight to recovery, the stock recovery would still load. This guy told me to flash TWRP, then to run the command to relock the boot loader.
What happens now?
The phone will only load to this screen, and will reload it every time I try to turn the phone off. I can't get into fastboot or recovery mode. If I drain the battery, then plug it back in, the phone will turn on as soon as it has enough power and boot into the OS fine, then will die from low battery and go back to the error screen. The phone does not appear when using ADB devices or Fastboot devices.
What I've tried
Getting into Fastboot
Getting into Recovery
Loading the phone
Forcing an update from SD card.
All of these just give me the same error screen
If anyone can help me to recover this phone it would be great appreciated.

I Need Help For LG G3 Unbrick (Qualcomm Drivers Not Working)

First of all i apologize for my bad english.
3 days ago I put my phone in brick mode and while searching how to solve this i found i need qualcomm driver.
I downloaded and installed the necessary drivers, but when I connect my phone to the computer, I get an error like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Can you help me solve this problem?
Notes:
-My phone is not charging and won't turn on
-i tried different qualcomm versions
-I tried these processes in windows 11 / 10 and windows 7, but it did not work

I will join this discussion, because i also have similar problem. I was trying to flash entire system to friends G3 32gb. But contrary to Sercan, i managed to install Qualcom driver following this guide (https://forum.xda-developers.com/t/q-wont-enter-download-mode-phone-stuck-in-boot-loop.3102900/), and finding driver, dll file and .kdz file on different sites from what guide posted. But whenever i open BoardDiag program and follow steps from the guide, when i select folder containing tot file and extracted files, BoardDiag program just shuts down and restarts from the beginning. Also i am unable to go to next screen after download mode screen, i start download mode but after that it seems like phone just shuts down (i have battery fully charged). I was also unable to flash it regularly before i tried .tot BoardDiag method. Any further help is appreciated.

Mi 9 SE - locked bootloader after flashing the wrong ROM

Hello.
I have a problem with the purchased used Xiaomi Mi 9 SE.
I bought the phone and it had an unlocked Bootloader, it was not possible to pay with it using NFC.
The phone was probably ROM 12.0.XXX I think Global.
I downloaded the Fastboot 12.5.1 EU ROM and flashed it using MiFlash.
When uploading, I checked the option - clean all and lock
The upload went smoothly and was successful.
Unfortunately, after rebooting the phone enters recovery mode and it is looped like this, it displays the message:
This MIUI version can't be installed on this device :-(
I can enter fastboot and try to flash another Rom but then I get an error that the phone is locked.
Please, help me with this issue, I don't know what to do, is it possible to fix it? ? ?
I know there are people here with really great knowledge, please help. :-(

I tried to flash the ROM Global 12.0.1 again but I get the error as above
I have Miflash pro 7.3.706

Try to enter fastboot mode and flash the ROM using the flash_all script that's insideof the compressed rom by way of windows cmd or linux terminal.
Just extract the rom file until you see the folder structure there with all images and then look for a how to flash roms using fastboot. It way easier than that miui flash thing
