Root Huawei GR5 KII L21 and Flash CM 13 - Android Q&A, Help & Troubleshooting

Please help me on how to root/unroot this Huawei GR5 (kii l21) phone running Marshmallow 6.0.1, encrypted( dont know if it's relevant),install twrp and if there is cm 13 for this phone. I saw the cm 13 for Honor 5x (kwi l21) which is essentially same as GR5.
Also how to roll back to stock version if the cm 13 doesnt pan out.
I cant unlock the bootloader as the Huawei unlock bootloader site says "sever busy" all the time.
Thanks in advance

root HUAWEI GR5 , flash cm 13

I posted this in the general section that may be why nobody responded. I am new at this so...
Help, I am asking again on how to root Huawei GR5 (KII L21) running marshmallow 6.0.1 and flash twrp, where to find cm 13 and how to flash it. It is same as Huawei Honor 5x except 5x has (Kwi l21 l22 l24) but I have no clue about what to do with this device of mine. It's not even listed as one of the devices in the xda forum.
Also there is no option to make a 3G video call, how do I fix this?

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!.

Huawei Mate 10 lite [OREO] How unlock bootloader and flash TWRP?

Good morning,
Can someone tell me how I can unlock bootloader (I updated android to oreo using update function on phone) but now I read that I must have android nougat to unlock bootloader

Can you unlock the bootloader, install TWRP, root and ROMs on a Mate 10 with EMUI 9?

Hi. I think I am going to buy this phone and I would like to know if I am going to have problems with EMUI 9. Surely, if I buy the phone it will already come with EMUI 9 installed. Can you descend from EMUI 9 to EMUI 8?
Although the service does not work right now, Ministry offers the unlocking of the bootloader for Mate 10 with EMUI 9. No?
If I unlock the bootloader in EMUI 9, can I install TWRP, root and a ROM?
Thank you.

[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.
