TWRP not flashing ? (G360H)

So I recently downloaded the RR Marshmallow custom rom , and when I flash the rom the twrp just re opens / restarts . help plz ? and also how can I flash .img files (kernels)?
Connect phone to computer and use Odin to flash TWRP, after that boot to TWRP wipe data and install custom rom.
You can use Odin or TWRP to flash img file.

Help needed, ze552kl bootloop after flashing without uninstall magisk

Last working state :
1. Android O version WW-15.0410.1803.55
2. Bootloader unofficial unlocked
3. Rooted with magisk
Reason for flashing :
Update to latest Oreo then re-root but flashing failed due to magisk not being uninstalled first
Current state :
1. Able to enter fastboot
2. Twrp is intact
3. Magisk uninstalled using twrp
Actions already taken :
1. Uninstall magisk via TWRP
2. Re-flash WW-15.0410.1803.55 via TWRP
3. Wipe dalvik/cache
4. Factory reset via twrp swipe
Still stuck in bootloop
I'm thinking of flashing Oreo stock recovery prior to reflash Oreo firmware via Asus flash tool. Found Oreo stock recovery image from 15.04.10.1711.6. Is this usable? (Edit : found suitable version and bunch of other versions, big thanks to Iceboy91 on following thread : https://forum.xda-developers.com/zenfone-3/help/request-stock-recovery-boot-img-stock-t3763381 )
But before I do anything even more stupid, I need your advise on correct next moves, guys.
Flash raw oreo via Asus flash tool and all will be fine.

Will Asus FT run properly on TWRP i/o stock recovery? Last time I did it booted to TWRP and I can't proceed. Kindly confirm if it's possible and I'll give it another try. I am left with another option which is flashing corresponding stock recovery and boot image.
To save your time from trial and error recovering from similar problem, here's what I do.
Issues :
1. Flashing raw on stock with TWRP stuck on eternal 'unzip image'
2. Flashing raw on stock ROM with stock recovery and wipe data OFF was successfull but could not enter system (stuck on Asus logo with circling progress).
Also unable to enter stock recovery at this point.
Steps taken to recover from bootloop :
1. Flash corresponding recovery and boot image to replace TWRP (BE CAREFUL WITH SOFTWARE VERSION)
2. Firstly, flash basic Oreo RAW firmware which can only boot to fastboot found on this post : https://forum.xda-developers.com/zenfone-3/how-to/updated-unlock-relock-bootloader-t3749456
3. Flash full RAW Oreo firmware found on the very same post mentioned on #2, but with WIPE DATA SELECTED.
Note : Step 2 might be skippable, up to you to try
Hey ,
If you wanna upgrade to latest Oreo update, just follow these steps (most of the users did not report any kind of bootloop)
1) Flash stock recovery
2) Sideload the latest firmware .zip
3) Reboot and flash TWRP & Magisk
Link for stock recovery/boot images by @shakalaca :

If anything happens, RAW firmware is there for you
Note: Do not remove/uninstall Magisk via TWRP. Flashing latest update will remove Magisk automatically.
Thanks for the tip, my problem has been solved, but better solution is certainly welcomed. Will do when caught in the same situation.
Here is what I do:
Skip automatic update and do it manually through TWRP.
First flash update then reinstall latest magisk in order within TWRP.
Reboot.

AFT just needs working fastboot.
Flashing raw via aft will restore all stuff to stock state.
Twrp will be replaced by stock recovery too.
I wouldn't recommend flashing stock zip via twrp.
Another way to get back to. Stock is to replace twrp by stock recovery (after wiping data, cache, system). Then flash boot.img and finally use update via SD card option from the newly installed stock recovery.
Also you can take twrp backup of stock rom (system, data, boot) and restore whenever you want to go to stock (after wiping system, data and cache).
All methods tried and tested.
