Yes did everything. App did not ask it but the permissions were already ticked. I also checked app ops and tried unticking and running and then re-granting the permissions but nothing worked. After searching came to know that it is happening with others too on 7.1.1 custom rom (of other devices). So it may be a hike bug

Someone also said to modify app contact sync stuff by adding run time contacts permission codes, which I dont know how to.

Because if you lock bootloader on a non stock kernel, the phone won't boot. I am not familiar with QPST, but it should be able to work in fastboot. So, lock bootloader and then use QPST to flash the rom without reboot. Or, install stock rom, then after locking, you would be able to boot...

Yes,you are right

It is not booting.

But also it is not able to flash in fasboot mode.i tried to flash in fastboot mode but it is not working .All other command working like Flashing recovery or unlocking in fasboot( which means drivers are installed perfectly).but when i try to flash then it says boot into edl or download mode.i tried and stucked in bootloop.because i am not running stock rom and kernel.look into this matter when you get time.

Review after 1 day of usage

Rom is pretty smooth, never felt like that even on stock rom. Even the device is much cooler now even when taking antutu benchmark, stock used to heat sometimes and lag (occassionally only)

Battery life is pretty amazing too, 9% screen on time over 1 hour (used antutu in these 9% else was on WiFi and surfing net using chrome during this time)

Tried VoLTE during first time and it worked. GPS works too, using device only and the location is fixed in around 30 seconds (first time was 1 minute)

Antutu benchmark is impressive too (138559 for 3Gb variant)

Overall very smooth rom, no issues so far.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Ferrari1976:
Thanks you for your help. I got VOLTE working on stock ROM 2.5.104. Finally, it took a simple change in APN Roaming to get it working.

To get to 2.5.104, I installed 1.9.044 using QPST, followed by 2.0.093, again, using QPST.

To get OTA updates, I had to use FlyVPN, select a chinese Server, but did successfully update to 2.5.104 in threehops (2.0.093 to 2.0.111 to 2.0.133 to 2.5.104).

Volte was still not working. Finally the APN change did the trick.

1) APN Protocol: ipv4/v6

2) APN Roaming: ipv4/v6

3) Bearer: LTE

To answer your question on QPST, I was using Jaguar (bootloader unlocked) and I used "adb reboot adl" to get to download mode. QPST flashing was smooth using the directions on the zukfans forum.

Will unlock the bootloader, install TWRP and Jaguar to check if VOLTE still works and report back. Thanks again.

Most of the time I do dirty flash, but I don't jump from rom to rom. However, after doing a clean flash on the latest release, I have noticed overall improvement in speed and smoothness, which may actually be due to 03 flag.

I have not, but if anything is broken, then it should have been the same on prior releases. No changes related to Magisk were made, except for updating to the latest magisk manager.

Known bug. Happens with other users too of Lineage OS based roms of Moto G4 Plus

Solution: Restore titanium backup taken from other phone or

3. Open playstore and update hike

4. Profit

But remember in both methods, your phone contacts will not be displayed to phone numbers and you can't send image directly (use send document feature and select image file)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
First, learn XDA rules and stop posting quotes that take the whole screen. Don't you know how not to do it?

Second, volte depends on the baseband you have and the way it is installed. Volte works fine on Jaguar, especially in India, as confirmed by several users. Third, even if you converted to f2fs, which in my view, is far inferior to ext4, that only covers your data partition, as system is ext4. Fourth, if you stop flashing roms 3 times a day, you might discover that your phone no longer heats. And fifth: there are only 3 roms in Android universe that are NOT based on Lineage: Slim, DU and Jaguar. And that's why, they are far superior to the rest of the crowd, who 99% of the time just copy and paste from Lineage without even understanding what those commits do. CM was good until they created Cyanogen Inc and came up with their monster bloat CM SDK. Unlike CM, which deserves a lot of credit, Lineage, nowadays, is no different than bloated stock. In fact, the only difference is Lineage has more bugs...

For system, it is always ext4, nothing else. That's the script:
