Non modified version of the OS for BluBoo Xtouch

Hello,
I need to install a non modified (customized) version of the OS Android 5.1 in my BluBoo Xtouch. Because BluBoo provides a custom rom (I've updated to the last version provided), this brings me trouble to install some apps. Anybody know how can I do this (non modified version of the OS Android 5.1) ? Any support will be very appreciated.
Many thanks

Hello prabin__,
Thank you for your response. I tried lineageOS, it was very slow and i can exploit it.
So i returned to the official ROM.
My problem with this ROM (EMUI 4.1.3) is that it closes background applications even if i make them protected.
I want to have a performant rom working with simple sim (not LTE) that does not close the background apps.
or an upgrade to EMUI 5 (I heared that it does not have this issue)
Any suggsestion is welcome.
Thank you.

I too am willing to install the Paranoid ROM because it's stable. (https://forum.xda-developers.com/p8lite/development/rom-t3649258)
But it says that in order to install the ROM the phone has to be updated to EMUI 4.1 B895/B896 and the TWRP version must be 3.1.1 . And that's probably related to the p8 lite and since I too have got a y6ii and my current update is, EMUI 4.1.3 CAM-L21C636B190,
I'm a bit confused, should I too have to update my y6ii to the aforementioned EMUI version?
I also currently have TWRP 3.0.1 installed on my phone and I guess I need to remove it and install TWRP 3.1.1 right?
Can you advice me on this. Thanks!.

[QUESTION] How to upgrade kernel in Huawei P20 Lite?

I want to upgrade kernel in Huawei P20 Lite from 4.9.111 ---> 4.9.148.
I tried to flash kernel 4.9.148 but, after flashing the phone got stuck at bootloop untill I rolled back to kernel 4.9.111.
You may say why I need to upgrade kernel to 4.9.148? Because I have Android 12.1 GSI installed with unlocked bootloader and I wanted to install Android 13 but, it didn't work and the phone got stuck at bootloop even with VNDKLite GSI, after that I saw in some thread that I must have kernel 4.9.148 in order to get Android 13 GSI working on Huawei.
I don't want to flash EMUI 9.1 Firmware because it will lead to relock bootloader. Anyone knows how can I upgrade kernel?
Note: Current firmware base installed is EMUI 9.0 with kernel 4.9.111 on Android 12.1 GSI and all GSIs work up to Android 12.1.
