Lollipops problem after Chinese Lollipop rom

Hi, i was on official leaked lollipop Chinese rom, until Russian official lollipop released.
After wipe and format all thing with twrp and flash 8gb pit file and flash Russian official rom there was a lot of problem, device was so laggy and when it went to lock screen and display turned off, there wasn't any way to turn it on except remove battery and put it again.
So after that, i flashed leaked Chinese rom again and all problems gone.
Now Indian lollipop released and i flashed it and all problems come again.
What is the problem? and how i can solve that?
anyone??
I'm having the exact same problem.
I was having difficulties installing custom ROMs and decided to go back to stock and try again... Now I can't install anything properly.
@Mohamadreza - Have you had any joy?
I take it you've given up?
I tried flashing both stock K and L roms without any joy. Eventually found an old backup. Restored that and now is is back to normal.
Hope your phone is alive again...

Well it is expected to give a Factory Data Reset after flashing the Firmware through Odin.
Flash the firmware and give a factory wipe from the stock recovery.
I hope it will solve your problem.(mine was solved)
All the best!
I found solution .
The solution is downgrade to kitkat rom and then upgrade to any rom you want like official lollipop
I tried flashing both official KitKat and official Lollipop roms without success. Restoring fixed my problem.
Glad you're sorted now.

Sorry, it is impossible to downgrade to 4.3 once you've upgraded to 5.0. You CAN however downgrade to 4.4 downloading the firmware from sammobile and flashing it with odin. But what do you like about kit kat that Lollipop doesn't have?
If you really want 4.3, flash a custom ROM that is based off a stock 4.3 ROM.
in status bar was notifvation toggles the biggest and thats greeen color more confortable then lollipop 5.0 notification draw........ i dont like 5.0 android.

You could try Jellybean or KitKat ROMS if you feel those Android versions to be better. There's also Lollipop and Marshmallow
But when it comes to PURE AND STOCK Jellybean 4.3 downgrade, it is impossible.
All that was mentioned before is true. You can't overwrite the new bootloader with the old one. If you really want to downgrade, I recommend https://forum.xda-developers.com/showthread.php?t=2472301 . It's a very old Android 4.4.2 ROM. I used it when it was 4.3 back in December 2013 ( oh man,the memories! ) .It was a great ROM,maybe THE best one at the time. Stability,battery life and customization,it was all there. ROM died and the thread was closed because, I quote, "Thread closed and links removed as the OP is trying to push all his donation-only themes and paid for applications, which is in violation of the terms set out in this portal post and also counts as soliciting donations and commercial advertisement." ... he was basically offering skins for the Samsung keyboard for money. I still love the ROM, if you really want to downgrade, but I can't recommend it. Flash via TWRP 2.8.7.0 and you should be good to go (theoretically) . I would however recommend trying MagMa NX ROM (for a more stock feeling) or AryaMod Note 7 port (for customization). If you don't want a newer ROM,I recommend AryaMod 5.0 . It is based on the stock Samsung Lollipop.

u need root to be able to downgrade, flash the 5.0 firmware via odin, root the phone and flash a kit kat rom and you will be more happy than ever lol
Root isn't required to downgrade and the OP wants JB, not KK.

(XT1575) Issue flashing Lollipop Roms

I couldn't find a solution to this problem myself so I was hoping someone else could provide some insight. Whenever I try to flash any Lollipop roms whether it's stock or custom my phone gets stuck on the boot logo and reboots. I tried downgrading TWRP and flashing the stock Lollipop firmware then going to a custom ROM but no avail. Nougat and Marshmallow roms work fine.

You probably will not find a solution as no one has really developed a lollipop ROM utilizing the MM or N bootloader/ radio.
