Here's how I compiled TWRP with decryption support using your device tree.

1. Created twrp.xml in .repo/local_manifests/ with the following contents and ran the "repo sync" command.

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="omnirom/android_bootable_recovery" path="bootable/recovery-twrp" remote="github" revision="android-6.0" />
<project name="omnirom/android_external_busybox" path="external/busybox" remote="github" revision="android-6.0" />
</manifest>

2. Then I added the following at the end of device/lenovo/kingdom_row/BoardConfig.mk. Not sure if any other flags are needed but TWRP is working fine with just the ones given below.

# TWRP
RECOVERY_VARIANT := twrp
TW_THEME := portrait_hdpi
BOARD_HAS_NO_REAL_SDCARD := true
TW_INCLUDE_CRYPTO := true

3. Then I added the files in attached recovery.zip to device/lenovo/kingdom_row/. Directory structure given below. Edit: Some of the files mentioned below are also available here - https://github.com/TeamWin/android_device_oneplus_bacon/tree/cm-13.0/recovery/root

4. After that I just used . build/envsetup.sh, lunch and mka -j# recoveryimage.

Also, I noticed f2fs support when examining oneplus recovery and was also able to add it to our device too. For that I copied the following files and folders from the oneplus kernel to kernel/lenovo/msm8974/.

include/linux/f2fs_fs.h
include/trace/events/f2fs.h
fs/f2fs/

Then I just edited BoardConfig.mk, fstab.qcom, kernel/lenovo/msm8974/fs/Makefile and kernel/lenovo/msm8974/fs/Kconfig. The edited files are attached in f2fs.zip.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
sweeeet! thanks a lot!

regarding f2fs, i removed it because at that time kernel was unstable and f2fs caused data loss after every reboot
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] m8r-u4wc08:
You are welcome. :D

I am using f2fs now with encryption. Not sure if there has been any data loss. Haven't noticed any data loss or errors so far.

Hello dear friends! Why OTG does not work in any explorers? Does not work in media players, only on some programms as ES expl, an Tcm. Can you fix this problem? I very like this rom, and I want to browse my OTG files in any programms, Thanks a lot dear! :)

One issue which is new... volumes are VERY LOW now after a while: I mean, had phone ON all night, at 20 yesterday received a call, and it was OK. Now I tried to mess with the ringtones, and phone volume is almost unaudible. A reboot seems to fix, or at least make volume lod again? Very weird!

I am on 20-05 build, and it's almost not possible to hear the phone when there is a call in this situation!

Any fix?

Yes it works, I am on CN phone.

On previous flashed without problems.

BTW could you add date to recovery.img name to identify version?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] codymamak:
Tonight I had a reboot while charging (Phone on).

Cannot tell you more, as I was sleeping.

I know it happened because kernel auditor notification message of " applied on boot" was there with clock at 3.31am.

Hope this is just one random occasion as reboots are really annoying..

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] underr.t:
I had few of those as well. Not just in this (latest) build tho. Haven't figured out why is it doing that, but it happens only when phone is charging.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Crazy_hatteR:
Agree, only when phone is charging. Got 2 reboots for 2 week.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] codymamak:
Well' if it's ONLY during charge, it can be bearable. It's very important for me that there are NO reboot during use.

Also, I didn't see any for the past 3-4 days, only this occurrence during night charging.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] malaga82:
since we switched to default kernel i didn't have a reboot.

ok that i use "my" build for the kernel but should be 99% stable like the stock, and for me it feels good.

You could try enable last_kmsg generation since it's disabled by default, editing /sys/module/printk/parameters/always_kmsg_dump from "N" to "Y"

And then check after a random reboot for the files

/proc/last_kmsg

/proc/kmsg

These files are needed to check what is going on.

I think last_kmsg generation should be enabled, i don't know why it's not.

I googled a bit and found something, don't know if can be applied to our build

Charging / Reboot

Hello,

on the charging-reboot issue i may have some input.

I have a K920cn bought used with error.

Error was "Its rebooting during charge constantly"

What it actually did when connected to the Lenovo supplied charger.

There was some unidentified stock Firmware with some magic and the

russian Radio/Modem file.

So first i started with the CM port from frantisheq (thanks again)

and went on till now with ressurection remix 050516 (maybe someone has mercy and i get an OTA version)

All ROMS i tested have the same behavior:

on PC Desktop/Laptop

appr. 470ma ingoing USB current No Reboot

on Chinatown 2A Samsung counterfeit charger

1150ma Only rebooting when i try to wake the fone.

When untouched nothing happens. No difference if sleep or up when charger connected.

On Anker Single USB Quallcom3.0 decent.

1750ma One time reboot every time charger is connected. No difference if sleep or up when charger connected.

2 out of 4 after reboot charging idles at 150ma forever.

All test with adorable (from a technical viewpoint) USB cable.

Same Charger, Cable of unknown source, china found a way to turn used chewing gum into USB cables,

1500ma Stay alive when using while connected charger, also when wake up again.

but when connected sleeping, reboot once.

Battery Level for all Test between 35 and 82%

External Amp Meter (Fluke) was used.

Regards rollerkeller
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Drug_Store:
I have two small problems... when connect to pc by usb cable, can't browser files inside phone. Thought this was fixed already, but no.

Other problem is that I can't access intranet sites of my company. This also happen with stock Lenovo rom 5.0.2. But if I use LG G3 D858HK with 6.0.1 oficial, and can do it.

Any help with this issue? I have another issue, but later I explain.

i don't like the fact it's closed sources, miui not always runs well even on its devices...and i like stock UI over "candy UI".

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] malaga82:
well, 2605 nightly has the same behaviour as last nightly, gapps get screwed on these nightlies.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Drug_Store:
But on that same place, google said it would only be fixed on 6.0 onwards, won´t be fixing it on lollipop versions.

So I thought, as this cyanogen mod is based on 6.0.1, might be fixed... :(

This means, it´s not "safe" to OTA update from 2405 to newer version?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Saamyo:
[MENTION=436155]malaga82[/MENTION] What does the TEST at the end of the build name mean? Are these builds unstable?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] malaga82:
"_TEST" means that they have some new commits and i'm testing if they have issues or not.

about the new builds they said:

The 20160525 update was missing the bit in the install process where it backed up and restored your google apps, so it just formatted /system and installed itself.

The 20160526 update has those scripts. However, if you were on a 20160525 update that removed gapps, 20160526 isn't going to magic them back in for you. If you updated from 0525 to 0526 without doing anything, you will still have issues. Restore your backup of 20160524 or earlier, then update to 20160526 or later.

so we should be "safe" form now on.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] remont5:
20160524 and stiile have random reboots - sometimes one per day, sometimes 4 per day....

I have CN version with modem to Europe

what is the method to tracking what is responsible for this reboots ? any LOG of phone work?

btw, I have the impression that the wifi works still even though it is set OFF (you can see it in battery statistics)

great job malaga82 !
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] malaga82:
do you have reboots even on offline mode? Or only wifi?

just to ensure you have or not a "bad" modem version...with CN we didn't face this discussion, related to modem, that's on other devices does it matter.

or if you a faulty setting, or kernel setting...

About logs, or you grab a logcat when it happens or...well, we don't have last_kmsg generation enabled, it's on OP if he wants to.

As i posted, You could try enable last_kmsg generation since it's disabled by default, editing /sys/module/printk/parameters/always_kmsg_dump from "N" to "Y" and see IF it works.

Something about this generation could be disabled at kernel level.

p.s. daily build is online, make a backup before upgrade, in case you'll get gapps issue.
