Are you using the relevant twrp with treble? Can be found in the instructions linked in first page.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] venu44:
I have been facing a problem as of late where out of the blue the phone app stops working. I receive calls but I can't attend them because I'm unable to see the caller ID. Generally, I dirty flash and this stops happening for a while. But nowadays it keeps happening so often to the point it starts getting irritating. Has someone else faced something similar to this?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fangstergangsta:
i use the official twrp
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
That's your problem then. You need to use the one in the instructions. You can download it here https://androidfilehost.com/?fid=5862345805528044694
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fangstergangsta:
okay i will try!

I must to install addonsu to have root or only magisk?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] satej@123:
Yup that's the problem.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fangstergangsta:
when i wipe data like instructions:

Go back to return to main menu, then tap Wipe.

Now tap Format Data and continue with the formatting process. This will remove encryption as well as delete all files stored on the internal storage.

i have multiples errors :

could not mount /data and unable to find crypto footer.
failed to mount /data (invalid argument)
unable to mount storage
formatting data using mkfs.f2fs...
mkfs.f2fs -t 0 -r 16384 /dev/block/mmcblk0p56 process ended with error 1
unable to wipe data
unable to format to remove encryption.
fail to unmount /data (device or resource busy)
unable to mount the storage

i think this is my main problem
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
Only magisk for root.

Hi. I have another recommendation similar to NFS, but I found it even better. You can remove the GPU model because this one contains something similar.

Worth giving it a try and see what you think. I'm using balanced mode. Getting some fantastic SOT.

You can install directly from magisk. It's called LKT.

Possibly any issue with the LOS twrp and f2fs.

It's a bit long-winded, but flash the official twrp back, then format. If you get any errors reboot back into twrp until format can be done.

Once formatted in twrp official flash twrp LOS reboot into twrp and try installing ROM.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fangstergangsta:
i have the same problem with official twrp... since i flash TWRP to install LOS the first time after stock rom i have this error.

I can install LOS but i can't wipe nothing dalvik etc...

the only thing i found to override this error was to change /data format to ext4... but i can't wipe nothing i can only install LOS and others packages...
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fangstergangsta:
Okay now i have the last built with magisk but how to root with magisk?

And what nice modules to install for LOS with p2?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
Magisk gives you root as part of magisk. Should be active if installed correctly.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Tahir Baig:
Is the audio fx app on LOS 15.1 on the kuntao broken or something? It is very inconsistent. It does not work sometimes, and when it does works for a brief moment and then doesn't. Is anyone else facing this issue?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] DarkHoundOne:
It's broken, if you want an equalizer you're better off using viper from magisk.

---------- Post added at 07:44 PM ---------- Previous post was at 07:43 PM ----------

I'll give it a try.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
Kinda broken. it works perfectly for me, but after every OS update, i have to turn it off and on, to make it work again.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] 0101chaitanya:
I updated while I'm rooted with magisk now the phone is boot looping please help
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
Did you take a back up? You could try restoring the boot partition only to remove magisk (assuming that the backup was taken before installing magisk). If it boots then you could install magisk back.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] suvam69:
I own a 3/32 model. Someone suggest a good Magisk module for ram management.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] 0101chaitanya:
No backup . What do I do
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] prashu199:
It its because of magisk try puting magisk uninstaller in the sd card and uninstall magisk
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
A long way round would be to make a full back up as it is now to SD. Copy the LOS update to the SD card. Then do a full wipe and install LOS. Then back the boot partition up to SD. Then restore the previous back up. Then restore the boot from the second back up. You could do that without having to download anything. As you already have the LOS update.

Lol. That sounds crazy complicated but should work.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
I was ready to post a test build 3 days ago but something broke calls on my first sim slot. I could not restore call functionality even on stock ROM, so now I am hesitant to post the build here in case I damage someone else's phone. I suspect what might have caused the issue and probably "fixed" it, but is anyone here brave enough to test a build?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lyceus:
I use one sim, so if only one might get broken you can count me in and sent test build.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
Actually it looks like a common issue, I fixed it now. Just wasted 3 days for nothing. Will post the build once I reconfirm it's ok
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lyceus:
That's good to hear.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Cuvillier:
Could you include openmobileapi simalliance API files to the rom please ?

Regards.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
Here you go.

If you want to keep and migrate your 15.1 data and internal storage contents (only on incoming official builds!):

1. backup userdata in your current TWRP and take an internal storage backup on your PC.

2. reboot to bootloader

3. fastboot flash recovery twrp-3.2.3-20190209-kuntao.img

4. reboot to recovery by holding vol up + vol down + home + power buttons

5. main menu -> wipe -> format data

6. main menu -> reboot -> reboot recovery

7. flash lineage zip (and gapps/whatever else you want)

8. restore userdata backup and internal storage backup

9. delete /data/system/locksettings.db, you will have to set your lockscreen protection again when it boots

If you want a completely clean install just skip steps 1, 8 and 9.

I tested this process and it worked coming from lineage-15.1 or stock ROM.

New TWRP: https://androidfilehost.com/?fid=1395089523397888315

Test build: -removed, see my latest post-

MD5: 50635246a8364dc91c4223fc49de7c73

EDIT: You can't migrate official lineage-15.1 userdata to my unofficial build, you better wait for official if you want to migrate your old data.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lavesh05:
i dont

i dont have pc, so can i use "install img" option in my current twrp to update to latest twrp?? or there is any other way to update to latest twrp without pc
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] prashu199:
Thanks a lot brother for your hard work.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lyceus:

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Cuvillier:
Thanks for confirming, did you wipe the data without restoring it aswell?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lyceus:
Yes, I downloaded only core app via data and will be waiting for fix.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
What do you mean it's gone? Please provide logcat right after boot, because it works here
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
"Format data" in TWRP defaults to ext4 now. f2fs should also work, only formatted with new TWRP though.

Looks like the wifi issue on clean install was this commit was missing https://review.lineageos.org/c/LineageOS/android_device_lenovo_kuntao/+/241447

so next builds will have it resolved
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Liacon:
With this new twrp build we can use f2fs and use magisk?

Also, with this new build we will can dirty flash los 16 on 15?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
With new TWRP and any 16.0 build you can use f2fs and magisk. You can only keep your data from official 15.1 -> official 16.0 if you follow the instructions in my previous post.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Liacon:
Ok, thanks for the reply and for your work ..!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lyceus:

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
New test build. Previous steps repeated here to avoid confusion. Only clean install supported on test builds! Link will be removed once confirmed to work without issues.

1. reboot to bootloader

2. fastboot flash recovery twrp-3.2.3-20190209-kuntao.img

3. reboot to recovery by holding vol up + vol down + home + power buttons

4. main menu -> wipe -> format data

Other than WiFi, for some reasons GPS can't pinpoint my location in maps or any other app.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Tahir Baig:
That might be because gps also relies on WiFi for accuracy. I am not sure about it though.

About key store, I think there is issue because on an app that try to access secure element to my sim card I get internal error.

* GPS : OK

* Encryption : OK

* FP & gestures : OK

* Auto brightness : OK

* Bluetooth (tested with speakers) : OK

* Volte : OK

* NFC : Can't test

* WiFi not turning ON & hence WiFi hotspot & cast screen can't be tested.

Nice work Mike. :good:

Your calls working perfectly since then? how many times you booted up since clean install?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] DarkHoundOne:
CPL is basically the Pixel launcher with more customization, here's the link https://play.google.com/store/apps/details?id=ru.whatau.cpl , you can find the link for it's companion app on the play store page.

I've rebooted maybe 10-15 times because I installed Magisk, some modules and Swift Installer.

Also bro, do you know why Pixel Launcher isn't working in this ROM?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] DarkHoundOne:
I just tried installing the regular Pixel launcher from the play store and that seems to work fine, there was probably something wrong with the gapps package.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] :
Can we install Google Pixel L app from Play store??? You can move that apk in TWRP to system app folder.

Also i tried to download some 9.0 build of Pixel Launcher from apk mirror those weren't working.

It's been happening since 15.1 where the phone boots up with the wrong date and time and only corrects itself when it's connected to either WiFi or a working data connection, it usually takes a few seconds to do that so you get the WhatsApp notification.
