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.

NOTE 3 t-mobile soft brick problem

Hi, I flashed Cm 12.1 lollipop rom on my note 3 t-mobile. I was working good but would like to try dom pop rom and could not succeed to install it. try to install TWRP instead of CWM. but stuck while booting. so now phone enter de downloading mode. But can not enter system rom(lollipop was on it) and also recovery mode.
Can i flash Kitkat official stock rom on to Lollipop running system Because there is no Offical stock lollipop rom for Note 3 t-mobile. My phone stuck and soft bricked i think and got advised to back to the official stock rom is the easiest way. I was worry about if i hard brick my phone by flashing older version rom like kitkat. Is there any way to flash kitkat rom after installing lollipop rom.
What can i do at this situation? highly need help i would be appreciated for your help thanks.

(SM-910h) IM NOT ABLE TO FLASH STOCK FIRMWARE

Please I own a SM-910H version of the Galaxy Note 4. I tried to flash the N5 ported Sixperience rom but I was experiencing a bootloop because my bootloader wasn't a lollipop 5.1.1 bootloader. I downloaded the 5.1.1 bootloader (910HXXU1COH4) and for some unknown reason I'm not able to flash via odin. It fails whenever it gets to "sboot.bi". I tried flashing the stock firmware, both lollipop 5.0.2 and 5.1.1 but they all fail when it gets to "sboot.bin". But I'm able to flash Recoveries and 910HXXU2COJ4 bootloader.
I reverted back to stock kernel and recovery and still didn't solve the problem. I tried to flash CyanogenMod 12.1 via recovery it also didn't work.
Please I need help to fix this problem because I'm afraid it might affect me in the coming months if I want to flash android 6.0 Marshmallow.
Below are the information on my phone frmware

About updating sm-j730f/DS from Android 7.0 to Android 8.1 ?

Good evening, I have some questions taking into account that I am not an expert.
Beginning I own a sm-j730f/ds version Android 7.0 rooted by Magisk, 17.1 stock rom for Egypt:
1-Is it possible to update to Android 8.1 stock ROM for UAE
2. Are there any special steps to update or the normal way is enough by Odin
3-Does root with magisk work without twrp method
And thanks in advance.
Ok......
good afternoon friend you can help me .. so I wanted the back-up of j7 pro .70 twrp without root because I was upgrade to version 8.1 and to have several errors and I can not go back to version 7.0 only by backup
My dear friend, I am sorry unfortunately I can not help, because my device contains root magisk plus that TWRP does not work on my device.
Question why you want to return to Android 7.0. Have you encountered a problem with the new update?

J7 Plus C710F TWRP for Android 8.1

Hi xda community. I need some help for my J7 Plus C710F android 8.1 official firmware released last month. The last version of TWRP of @Albe96 for android 7 is working fine but for some reason my phone got a bootloop and i started flashing the latest android 8.1 version via odin. After that i activated the developer option, active usb debuging mode and OEM unlock then start flashing the TWRP recovery from @Albe96. The flashing process is a success but its not working and it goes back to original stock recovery. Can someone update the TWRP from @Albe96.
Here's the working version of TWRP for Android 7.1
