Upgrade to MM Asus ZE550KL Z00LD - Zenfone 2 Laser Q&A, Help & Troubleshooting

Goodmorning everyone,
sorry if i reopen an old discussion, but I find myself with a big one
problem on my smartphone Asus ZE550KL Z00LD;
I had problems installing the AOSP 6.7 custom ROM and thinking
, ignorantly, that it was a Marshmallow problem, i did the
downgrade to Lollipop, installing the StockBoot 1.16.40.763 and its
stock Rom Lollipop 1.16.40.763.
Now I find myself with Lollipop stock rom, bootloader unlocked (and therefore i can't
do no update to MM via OTA ...), and i can't install
no custom ROM from TWRP.
Can you tell me how I can update the ROM in Marshmallow and then
to install a custom ROM?
thanks a lot

and I can't install a custom room either

DM me ill give marshmallow firmware
flash it through twrp u are gud to go.

Resolved
OK thank you very much.
I solved it like this:
From Recovery Mode I updated this version WW_1.17.40.1531.
Then I installed an OTA update downloaded from a Russian site which allowed me to switch from the Lollipop version 1.17.40.1531 to the Marshmallow version 21.40.1220.1615.
Now it works perfectly both AOSP 6.7 Z00L and AOSP 5.8 Z00L
Thanks
Good weekend

Get flashable system img inside system folder. Its ww a500cg pre root. Install through twrp,
Select install, choose img. Hope it work, but for the signal losing, check your imei and baseband.

How do I update my bootloader from kk to lp version?

I want to install on my device the LineageOS, but for this I need to update my bootloader to the LP version. How I do this?
Just flash Latest lolipop based custom ROM.Search it in miui forum.Or flash lolypop firmware.U maybe find it guide section.
Just a advice .....before making a new thread about something just search a little bit if this has discussed before or not.
I think I made a mistake in my post.
It is .....Just flash latest MIUI (LP) ROM found on MIUI forum....
Edit:---
In the first line I typed custom by mistake.....
1)flash any latest MIUI LP ROM found on MIUI forum or xiamoi.eu
2)flash lollypop firmware if u found it some where.
3)flash thunder MIUI @gkalen latest version
U will get LP bootloader.....Go as u wish
U need to flash miui 6.29.9 ROM of Redmi 2 prime via fastboot to get LP boot loader
Just flash the firmware uploaded in lineage os rom forum
Flash miui Redmi 2 prime ROM
Flashing any custom roms before flashing prime's rom won't get u lollipop firmware

Yes you can but only with the correct custom recovery. Keep trying with older version twrp v2.8.6_no_image or cwm recovery, if you are somehow not able to do it
I think first you should install lollipop and then kk
