HELP regarding Upgrade to MM STOCK ROM OR CM 13.0 !!!

Hi guys, its been a few days since I joined here. [Read : I am a noob/newbie in Android related things, and I desperately need help.]
In July (maybe, I forgot), I rooted my ZE550KL, using exactly this method from the website of www-asus-zenfone-com. :cyclops:
Now that, my android seems aged, I wanna shift/upgrade to Marshmallow/Nougat, be it Stock or Custom ROM.
Few days earlier, I unlocked my Bootloader using the Unofficial Bootloader Unlocking Method, as found on this Forum.
I also installed TWRP Recovery, and I tried to flash CM-14.1 [7.1] Nougat-Nightly through TWRP, but, unfortunately, resulted in Status 7 Error. I tried to solve the problem by removing "asserts" section in Update-Binary text file, in the build. But, again, I seemingly worsened the problem; as I got Status 6 error thereby. So, I did factory reset, and I still retain root.
Now, today as I am going through the Official thread of CM 14.1 Nougat, I saw numerous users reporting Bugs of connection issues (something like Wifi to Mobile Data switch problem), which I would like to OBVIOUSLY AVOID, as I want a stable, bug-less build. So, I am thinking to go with the last snapshot build of CM 13.0 Marshmallow.
Here comes the my question : " SHOULD I FLASH CM 13.0 MM -- OR -- STOCK ROM OF MM -- OR -- RESURRECTION REMIX MM ROM?? "
In any of the case, please guide me through the process of doing so.
And, if I have to flash CM 13.0 MM, what would I do if I encounter Status Error 7 again ? :crying:

first you have to upgrade it to marshmallow using stock rom. Then you can flash cm13 or cm14.1

While flashing CM13 if that error 7 includes "asus.verify trustzone failed..." Then its bcoz of need to update modem files (LP to MM)....
Easy way to overcome it is..... download MM modem ZIP from second post of OFFICIAL CM13 thread (120MB) and flash it using TWRP (If you are using twrp).... THEN you can flash cm13 hopefully without error 7....
If you are using stock recovery then Either u can flash twrp and use above method... OR... Download ASUS ZE550KL firmware zip file from ASUS site (1.6GB) .... Put it in SDCARD... Then boot to stock recovery and use "apply update from sdcard" option... select ZIP... Alongwith firmware Ur Modem files will also update to MM... and now u can flash twrp and then cm13...
sorry.. I know if i am lazy to post direct links...
Try it.. I will help if i can

We have both stable RR and CM13.
CM is simple and clean and less loaded.... RR is most feature rich Custom rom we have alongwith stability...
Rest depends on what type of user, u are... If u like trying differnt ROMs... Start with CM13...
If u just want to have a feature rich longtime setup, U can use RR directly without wasting time... It is based on CM, So it obviously have everything CM has.... :good:

Custom rom doesn't boot

Hi Guys
I have my Galaxy S5 now +- 3 years, and use a custom rom about 2 years now...
Until now, I'm unable to boot any custom rom, everything freezes at the boot screen...
I was using Resurrection Remix Nougat, but can't update it, not dirty and not clean.
Today I flashed a stock rom with Odin, and I can't boot any custom rom except the stock rom...
Can someone help me please?
thanks in advance!

Check the bootloader and modem, if it's the correct version. Otherwise, recovery might be the culprit. Nougat ROMs are kind of sensitive to older basebands, though results might actually vary.

[HELP] Is my stock rom hardwired so that no other ROM can be installed??

Is it possible or is it with the recovery image im using
Asus Zenfone 2 laser ze550kl z00l is my phone model
I have tried many stockroms to install but only one get installed perfectly namely back2stock-1.17.40.1234.zip. Because of this i can't even install any other custom roms like i tried to install lineage rom but itstuck on bootloop
Any kind of replies and queries about my problem asked will be much help full

What im trying to tell is that my problem is not only installation in custom roms but i also cant install any other roms eiether from official site or some other site which means i cant install any roms accept the one the stock rom i mentioned above. And also i already tried to install MM firmware but it gives out error code 7 in twrp. I tried as i was said to install the previous version of lollipop before the update of MM came out but still i cant install them.

Which Android u r using now
Lolipop or MM

is your bootloader locked on unlocked?
just go back to stock versions for now
if u r on lollipop, download the 'next version' from asus
if u r on marshmallow, download the next version from asus
use fastboot (bootloader) mode to flash if required
when all is stable and done,
download & flash twrp
flash lineage 13, then lineage 14

I have already replied same thing on older thread, [ https://forum.xda-developers.com/moto-g4-plus/help/quick-questions-kernel-installations-t3794980 ]
if you flash ROM, it will also install kernel which is considered stock for that installed ROM. You need to flash kernel only if you have modified it (by flashing custom kernel or SU zips).
If you want to flash different ROM, you can flash without doing anything else, just wipe and flash.
PS invictaOS is discontinued long ago, invictaOS-Nougat is stable, Oreo will be more bugfull than current available ROMs..

Experience "failure to load kernel" issue after flashing lineage 17 OS and OpenGapps 10 stock... please share the solution.. do i need to load a stock kernel?

Though these forums are for the Moto G4 Plus, that does suggest an issue with the build of Lineage OS that you're using. Can you confirm with the developer that this build is successfully running on their device? Do you have a compatible Lineage 17 OS based kernel you could try to flash?
Was your device working with other stock or custom ROMs before flashing Lineage 17?

You need to unlock bootloader and install custom recovery, cause they are not signed by manufacturer hence you cannot flash them like the stock cyanogenos.
You can use LineageOS or other roms based on this. Just flash gapps and you have Google maps. But you also need cm13 firmware before using LineageOS 14.1 or later.
Just search a little bit here since everything is discussed.
