Stuck in Boot Logo after Restarting! - Galaxy S III Q&A, Help & Troubleshooting

I have just flashed a new ROM (LineageOS based Nougat 7.1.1), and everything was working fine but when i tried to reboot it, it powers off and then it opens up and shows Samsung LOGO and nothing happens after it, i don't see the boot animation of the System.
P.S: it is not a bootloop i am sure beacause it doesn't boot again after the logo is gone it just keep freezed black screen without loading OS.
Can anyone help me i'm really in a big issue

Try reflashing the ROM, flashing a stock ROM, or wiping data/cache from recovery.

[Q] bootloop, no recovery, continually restarting, Help mtk6592

I tried installing that lollipop rom but it just messed me up. I rooted the phone and tried to install the custom recovery for it. It said that it was installed but when I tried booting into recovery it would just stay stuck on the energy sistem logo. I could restart it and it would work fine but I then tried flashing the ROM with MTKdroidtools and it just put my phone into a bootloop. It installed its own recovery too which doesnt work, it just gets stuck and bootloops. Please help me. I just wanted my phone to look like lollipop. What can I do?
There is a way that I can install stock firmware back but the phone needs to remain off. Everytime i plug it into my laptop, it turns off. I tried ADB but it doesnt stay on long enough to do it. Help me please.
My phone is an: Energy phone pro

stuck at logo

Hi everybody,
i tried almost everything, so why don't try asking to you?
i rebooted my perfectly working smartphone, just to refresh it... a little... and i'm stuck at logo since then
i tried
-dirty flash
-clean flash
-fastboot flash all
i tried latest 12.5.7.0 but also latest xiaomi.eu and miuimix
on boot, during Redmi screen, it doesn't vibrate as it always did (this is very strange to me) and then in the MIUI logo (or any other) it just stay there until it reboots in recovery mode after near 30 minutes
recovery and fastboot mode work perfectly except vibration, which is not working neither in recovery
i'm open to any kind of suggestions
please help me
