BusyBox can't be installed, says that installation path could be the problem??
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
For the same reason: whatever you did, but when you were restoring data, you also restored system, which means you are on r11. For the future, when restoring data, deselect everything else.

Now, you already have saved data. So, install r13 clean (wipe everything), then restore data and you are all set.

So, now full steps: TWRP; wipe system/data/cache/dalvik; flash r13, flash gapps; restore data; boot; then back to TWRP and flash Magisk or Supersu.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
figured it would be the case so I did just that - backup everything, wiped everything, flash the rom then restore data

r13 is up and running now, so I need to choose sched governor to activate EAS?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] rahul.karuvath:
Did everything as per the instructions, restored only data after clean flashing r13 nd gapps. Phone boots up and after some hours of usage system stars to lag every moment. I didn't changed anything, even clash of clans game also becomes laggy, took long loading time and also overall performance are lags.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
In Kernel Adiutor switch to Performance governors in Big, Little and GPU. EAS is supposed to take care of battery savings. As I said, EAS is experimental. I am testing it myself...

Also, if you have been playing for hours, you might have some throttling to prevent overheating. So, again, in Kernel Adiutor, in Thermal, adjust temperature (the first one up a few degrees)...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
No. That won't help. There is a glitch starting from r12: if you flash it clean, you won't be able to make calls. If you flash dirty or restore previously saved Jaguar's data partition (in TWRP), then everything is fine. I have tried to revert many commits, but can't find the one responsible for this.

I have issues with installing r13. Currently I am using your r12.1 but I can't install r13 because of incompatible data error. I haven't used any other ROM nor doing a fresh install. Will it be enough to backup data partition on current ROM (12.1), delete all partitions, install r13 and restore data from r12.1? You said that the error with incompatible data is just a one-off but I have this problem again...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Animel:
Will you add Vox Populi power HAL

To the rom?

https://github.com/EAS-Project/android_device_voxpopuli
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Yes, it would be enough and what I said about the one time deal is also true. You were not on r12.1, because when you were restoring data on 12.1, you accidently restored system partition too and went back to r11. That's why you got incompatible data. TWRP by default saves everything and then restores everything unless you unselect everything except data. I had no trouble flashing r13 on top of 12.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] yash296:
Even I got the status 7 error even though I didn't restore system(as I backed up only data and did a clean wipe) while updating from r11.1 to r12.1. Anyway I backed up data from r12.1 and updated successfully to r13.

Performance has definately dropped a lot. I'm running it on performance governor too as EAS is supported but there's still lag all the time.

I think you should release a kernel without EAS that supports the new blobs.

Good work and thanks!

After changing the CPU and GPU governors into performance mode and thermal adjustments the overall fluidity and performance lags a lot. Is it improve the performance significantly?!! Or anything to fix?

---------- Post added at 08:13 AM ---------- Previous post was at 07:23 AM ----------

For information : i just changed the CPU governor into nightmare, GPU into performance and the first thermal adjusted to 75. Now the rom back to action with fluidic interface and performance. But need confirmation from optimumpro that is it safe to stay in this settings.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Nightmare and Impulse governors with noop schedule work fine. I got Antutu score between 132-139K vs 140-144 with my standard kernel, but during the test CPU temperature didn't go above 40, which is unheard of. In standard kernel, the temperature went above 50.

I didn't realize that our friend Star_King12 included several commits by a known kernel "expert", who likes to call his "creation" dark moon. In one of those commits, the "maestro" went in to mess with CPU voltages. He commented that Z2 were known to overheat, that's why he was reducing them. Well, Z2s are known to overheat with Dark Moon kernel only and for different reasons. So, my recommendations are (until I reverse those commits):

1. Increase overall CPU voltages by 15 mv

2. Use Nightmare or Impulse (I like it even more) governor for both Big and Little

3. Use Noop schedule

I am not giving up on EAS yet. It just needs some adjustment, and the thermal state is far superior to non-EAS kernels.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] rahul.karuvath:

Just a query, doesn't undervolt increases battery life and reduces heating. So if its stable at -15mv then why increase it?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
unless it's not stable at all. My phone rebooted twice when I turn off the screen after undervolting, while stresstesting it with benchmarks is fine. Even after uninstalling kernel adiutor, Im still not 100% sure that the phone is completely stable

The "default" voltage should be default, if -15mv undervolting is already working for you then you dont have to change anything

Jaguar standard kernel with the new camera driver, without EAS and with modules is live in post #3. Just flash in TWRP, apply Magisk or Supersu and reboot
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Well, uninstalling Kernel Adiutor in this particular case would make kernel unstable, because default Interactive governor does not work well. However, Impulse + Noop gets rid of any lag.

Not necessarily. By undervolting (reducing juice for cores), you make kernel work harder (takes more cycles to do a task).

You should ask in the thread for that rom. Normally, it is 2150 for big a 1593 for little. There could be many reasons you are limited, including heat, especially, if you made changes in thermal in Kernel Adiutor.

May you tell me your mobile setting of kernel freq and other to get 14k benchmark because in default setting i am getting 12.5k????
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I use default settings and stock battery savings. Actually, battery optimizer is not on at all. What's more important for a test is that your phone is not doing anything during it, such as: syncing, emailing, messaging or even querying provider's radio tower. Just put the phone in airplane mode for the test. Also, make sure your phone is not charging. I am not sure about benchmark, but my antutu scores are steadily between 145K and 150K, as you can see in screenshots (post #2)...

RE: 4G signal, especially if you flash different roms frequently. Just clean modems in fastboot:

fastboot -i 0x2b4c erase modemst1

fastboot -i 0x2b4c erase modemst2

and reboot...

Edit: to anyone who have problems when Magisk is set to 'hide root': the problem is not the rom and not even Magisk. It is Gapps. Gapps have to be flashed right after the rom and before Magisk. Otherwise, Magisk won't let Gapps have proper permissions. That happens because Magisk comes pre-installed. So, to fix that, just reflash Magisk separately after flashing Gapps and first reboot. As I have already said, I will remove Magisk in the next release...

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Jaguar is using Qualcomm's boost framework that speeds up interface transitions by about 40%

Heating? I don't have anything like that. Just let the rom be for a few charging cycles: there is a lot of things system does after first install. But if you change roms frequently, you really don't give time to each rom to settle: as a result, you will never have stability or good battery life...

Here is your problem right away. You are not on release 13. Your security patch says July. Release 13 has August and new camera blobs were only implemented in r13. When you were restoring data, you also restored system, which you should never do. You have to be careful in TWRP: if you want to save data, untick everything else. If you want to restore data, also untick everything else.

So, this time, make sure your data is properly saved, then do a clean flash of r13, then gapps, then restore DATA ONLY, then flash August 13 or 14 kernel. Then reboot. Then back to TWRP and flash Magisk.
