If you can get into recovery, then goto recovery--> wipe --> slide to wipe and then reboot to system. If it doesn't work then redo all the steps again from start.

Also would be helpful if you mention:

1) your baseband before flashing android p

2) which rom you were using before flashing crdroid

3) did you follow the guide step by step?

As you told , I try this method.

Yes I got amazing results without heating or lag.

Thanks for that.

Everything is working charm fully.

No Fc.

But one think is missing fingerprint scanner.

Why I don't no?

I try you method with step by step.

After login it directly took me in playstore.

No backup restore like app only + nothing asked to me screen lock or any fingerprint verification.

After search in setting about add fingerprint but no option.

I add pin then also no fingerprint option came up.

Help me.

Due to privacy.

I am college student and my friend like see insta or Whatsapp.

So help me from out
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:
1) Install any root explorer

2) navigate to /vendor/

3) open build.prop

4) find this parameter: fingerprint persist.qfp

5) if it saya false, change it to true and save.

6) reboot

7) if you get the option back, then setup FP as mentioned in first post

8) if no pixel imprint option appears, keep using the phone as normal for a while, it will appear automatically. (give it a few hours to a day)

if you still dont have FP option, then setup faceunlock and remove it, another user got FP settings by doing that

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] varunbiday:
I've found a way to get it working faster. Open Security page in settings, lock the phone and unlock after around 10 minutes; it usually appears. Then if it doesn't work when placing your finger on the sensor, stay on that screen for 5-10 mins also.

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:
IF you followed this tutorial step by step with the files mentioned in the first post, CRdroid must work. I can't provide guide for PR1 because I have not used it myself (I heard that there are more bugs in PR1 than DP5)
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] pipyakas:
I can't use the Pixel Setup, it can't load because the "Finishing system update" stuck at 30% way through

There's no option for the fingerprint, and dt2w doesn't work. There're also some small graphicall oddities like the QS toggle doesn't fit in the Notification center frame

I didn't try dp5 and went straight for pr1 today, but reverted back to my old rom for now.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:
Yeah PR1 also locks HALs so there might be camera Issues. However, DP5 is mostly stable and almost everything can be fixed and the phone can be used as a daily driver

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>UPDATE<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Hey guys, have been testing some settings lately and found that using these settings increase battery and decrease heating even more (my phone finally feels cold to the touch when not in use:

1) Turn off USB debugging from developer options

2) turn off double tap to wake and lift phone to check notifications (new notification can be kept on since that works)

3) turn off stay awake from dev options

4) turn off automatic system updates from dev options

5) turn off camera laser sensor from dev options

6) turn off mobile data always active from dev options

7) switch to 3g mobile network (for non-jio users, optional but very effective for heat)

I have two questions.

1. I am currently on AEX 5.5 (Treble). Do I still need to flash CrDroid or my current ROM would do just fine?

2. What abut GApps? Do I need to use GApps for 8.1 only?

Thanks in advance.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:

only one bug is here when ever you reboot the phone the fingerprint aka pixel imprint are not working .you have to re-registered the pattern and fingerprint
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:
Install google play services (the one linked in the first post) and reboot.

for wifi QS and other alignment issues.. enable developer options by going to system and taping on build multiple times.. and then within developer options change "smallest width" to 388
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:
after reboot, it usually starts working on its own if you give it a little time, or just choose add fingerprint and start registration of a fingerprint and if the registration worked, cancel setup and it should work perfectly (DP5 seems to take its time recognizing our FP reader)

Workaround which is working for me, after you restart go into the settings and search "pixel imprint" if it's available open it up and it will work for you, if it's not there try again after restarting.

So after a whole day of trying out stuff, some notes I have:

- Flashing the GPU driver seems to break the POST sGSI zip 1, due to it messing up with the vendor partition

- crDroid as a base also break POST sGSI zip 1 for me, but maybe it's just the gpu driver as noted above

- AEX as a base can boot both DP5 and PR1, but the performance is abysmal for no apparent reason

Im currently using the EOL HavocOS as a base and no obvious bugs or problem yet, and almost all hardware feature work. I haven't setup the fingerprint though, that would come next

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:
I made the guide after a lot of trial and error. I have personally never faced any issues with Post zip 1 due to GPU drivers. the problem with havoc is the battery life, its almost half the battery life compared to CRdroid and also the havoc shows heating issues. Maybe you can try using the TWRP mentioned in the first post and also completely wipe the device and retry the process.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] pipyakas:
Im already on that TWRP though. Maybe I would try another rom as a base.

Also, treble kernels like Nameless works with this, so if the batterylife is bad you can try out different ones

How did you get the fingerprint to work afterwards?

You can get PR1 and 3 POST sGSI zips here, it's the official link

Im running PR1 based off crDroid now, and aside from the fingerprint which I havent got it to register yet (it still acts as a back button in the "Touch the sensor" screen), there're no obvious bugs. You can root with magisk and change the kernel to whichever treble-compatible kernel you like (Nameless, Kroniccore etc...)

After that pixel imprint was going off and on. Then when it came, I went into it and before giving the thumb impression I let it be still for 10+ mins. Then came back and still was not working and then went back and again came and tried it worked suddenly. I dont have a fixed method but I was doing things around this only.

But how is the stability of PR1 with crDroid? what about battery performance and smoothness? And how is the camera ?

But the procedure needed to install P will be really difficult for a noob (especially if you need the phone for daily use). I would suggest to unlock your bootloader and start getting accustomed with custom ROMs in oreo. In a little while P will be widely available for the device in beta versions.
