[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Do the following steps:

Flash stock rom again, unlock bootloader, reboot, flash TWRP. After flashing twrp, when you reboot, immediately press and hold volume up+down after the phone vibrates. Do this quick. Now you'll see a black screen, don't do anything just leave it there for 5-10 mins. After that, press the power button, you'll see the twrp menu. Now go to settings and reduce the brightness to 10 so that it doesn't happen again. That's it... :)

Note: Before rebooting, mount system and flash aroma file manager. Now in the file manager navigate to system folder and delete the recovery-from-boot.p file, otherwise you wont be able to boot to twrp.
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] mangesh1256:
Wait for minimum 2 min for phone to reboot into recovery..!! It takes time for me also..!! ☮️
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
If you have set your brightness to 10, then you dont need to wait. It will automatically boot. And in my case, i even set the vibration to low, because even if there is low battery twrp can be used. :)

I managed to port your rom to my device (using my device's 3.18.19 kernel + some ramdisk modifications) but not the Zormax's rom, does that mean I will not be able to port your future updates as well?

Hey , unfortunately yes, you can port any roms from this device in future.

As this rom uses Nougat kernel, you can't port it with marshmallow kernel.

But I got you another way ?. I am maintaining for another device Coolpad note 3(mt6753) based on marshmallow kernel. You can port them :)

Better Go through previous posts of OP !
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] BBird5000:
I do know your situation, and in this case there is a feeble chance of help. I was pointing out some error and bugs. I never meant to irritate you. I am also a student, and I am trying hard in gathering some money so as to give you for your phone. Please understand, if you were aware of all these then you could have replied me earlier and thereby I wouldn't have disturbed you.

I apologize, if any of my words has hurt you.

Data Consumption and Speed bug is known issue and yet to be fixed, it is broken since last updates or so.

Bugs and limitations are part of custom ROM and we all are aware of that.

There are other bugs as well like some sensors and camera and he might have fixed all the bugs by compiling Zormaxs source code unfortunately he lost his device at very crucial time.

Volte will never be available on any custom ROM.

[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Ok. So since you already know the procedure for flashing the recovery, try the recovery mentioned in the first post. And i actually quite didn't get you. Where do you get that error message? In adb? Or on phone screen?
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] iyer78:

[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] mickemousse:
The error appears when I am on the TWRP screen when I slide to install the ROM says: "This ROM can not be installed because the terminal is not compatible" but when I install another ROM It installs without problems. I could not do screenshot but I just have the attachment so you can see the error and help me.
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Yes. You can post the attachment if you want. This error is occurring because you are on the wrong twrp. What I suggest is, you flash the twrp recovery mentioned in the OP. That one is made for mohancm's RR. If that doesn't help, then flash the stock rom again, and do everything from scratch.

You can port it with that kernel

Hey, I guess I messed up something. :p Flashed accordingly, and booted into the ROM. Tried to open AudioFX. But it didn't open, then showed AudioFX stopped working. Another one is that, when I went to File Manager, it showed some error and showed Cannot perform task, have to enable root access. AFAIK this shows only for external storage, but i don't have any, I'm on internal storage. I have to doubts, whether if this is only occurring to me, if so, can i directly re-flash from the N-recovery or should I go back to 1st and then continue?
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] mohancm:
for audiofx, dont know about this.

send me the log, i will check that later.

use any third party file manager. this happens for other devices too

that error is quite normal in most of the devices in nougat platform.

because of this lineage included another file manager with minimal features.

better use any third-party file manger:o
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Well, thanks for that, I'll try that. One more problem is that, I accidentally flashed the recovery 3.1.1 from the N-recovery, now it doesn't boot into recovery. :(
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] mohancm:
this is the issue,

so i wrote clearly about flashing procedure.

[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] BBird5000:
I can't say whether this is a bug or a new feature.

During charging my phone after the installation of latest version of RR V4.0 there was some different thing happening with LED notification. When I turned off the screen(not shutdown) there was normal red colour LED notification for charging ; but when I again switched the screen on the LED notification turned blue , even though the battery was not totally full. And while operating for few minutes the LED notification turned to an intermediate colour (purple or pink), both the LED glowed. Then again I turned the screen off, the red LED notification glowed. Whenever I did this, all the same happened every time as mentioned above.

Please tell me whether this a bug or a new LED notification feature.

(I installed and uninstalled the Light manager app, but nothing happened)

No Vulkan API graphic right?

Temporally fixing for NO SIM :

Go to Setting - then APP - Contact - clear 'Cache' - 'force stop' - 'disable app' - then restart(opt 'enable' it and then restart might work) your phone.(not gonna work if you install dobly via magisk)

Fixing for magisk & rooting : Just flash latest SuperSu(do not download magisk modules SuperSu). Don't flash 'superSU magisk' It'll only root you device for Magisk.

Bugs :

1.WiFi hotspot, people can't connect even its working and 5hz does't support only 2.4hz(was working in RR marshmallow).

2.Camera's FPS are very bad(already mentioned)

3.In Configuration - lock screen - there Upper shortcuts that doest work(I don't know what it is for)

4.There's no option for changing the Rows for Status(I guess cuz I don't find any) like it was in V1.

5.There's google launcher also(I don't it is bug or for just utilizing, found 3 launchers 1.Google L, 2.Pixel L, 3.Cyanogen L.)

6.And developer your given File manager bugged(cyanogen file manager) can't open External only Internal even fully rooted.

7.ROM not properly rooted(just mentioning)

8.The Power off just restarting the device.

9.Nothing like Usage data, no data limitation and also lack of incoming/upcoming data status.

10.Video playback does't support 720p+ only 480p-.

This are the bugs that I encountered BTW Great work Kudos.

PS : when you re gonna make new TWRP, its work but bug black screen timeout(temporaly fixed) also not saving setting after restart TWRP.

Edited : 11. Status bar tile doesn't fully utilizes as lower portions of tiles can't be added to use as screen tile.

Gonna research more..
