[MENTION=375661]philje123[/MENTION] if i remember it right, i've read on a website, that if you upgrade android / lineage OS and forget to install the correct "gapps" before you first boot your device, when your old android system had gapps installed, it can cause serious damage to the system.

they warned, to NEVER boot a new android, without the correct gapps, if you upgrade an installation, because that damages the system and can cause non booting soft-locked phones or other problems.

a few sites earlier you mentioned, that you have forgotten to flash gapps with your first try, so all google apps where crashing. maybe i can find the website again, where i read that informations, but according to them, people who have forgotten to flash gapps before the first boot, should factory reset the system.

i don't know if those informations are correct, probably [MENTION=7003377]GuessWhy[/MENTION] did the same mistake with forgotten gapps, but that would be an explanation why your system is messed up.

as i said, i don't know if that might me the cause of it, but because you've made a mistake in the flashing / upgrading process, it could be possible.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] GuessWhy:
I have never forgotten about it.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
Hmmm, all i've found, is some users here on XDA with another phone had those problems too. they managed to get rid of the problem, by uninstalling specific apps. maybe both of your are using one of this apps? XDA gesture navbar for example: try to fix it by reading this thread https://xdaforums.com/zenfone-5z/help/recent-apps-t3819468

i know other phone and system, but probably the same cause? one of them fixed the problem, by booting the phone into safe mode - then it worked again. on another site i've read, that wipe the "cache" partition did the trick.

Is anybody able to connect to WiFi networks that use EAP SIM? I am trying to connect to the London tube WiFi network, but I've had no luck so far. The network gets "saved" instead of "connected".

A brief search on Google showed EAP SIM issues on LOS a few years ago, but no recent information.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
Yes. Twice. Neither was successful. I'm not sure if this is down the f2fs though.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Tahir Baig:
I tried it 3 times with f2fs and failed to update automatically. But then I switched it to ext4 and successfully updated yesterday's update.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] philje123:
So I think my problem is gone.

I have since wiped system, cache and dalvik, reinstalled Lineage and flashed gapps again.

So far the recent apps are working and my battery drain from "NETLINK" has gone.

I also uninstalled Greenify and removed a GMS doze module from magisk.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] MAILUS:
Not working for me. Clean install with f2fs filesystem.

@ Uniposka

EAP-SIM does not work on Lineage OS, though I had it working on Lineage OS 14.1 on kuntao by replacing the wpa_supplicant binary by the one that comes from Lenovo's stock rom and I suspect this still works with LineageOS 15.1 and LineageOS 16, but I haven't tried it (because I want to limit the amount of proprietary software I run). I suspect this works on other phones too.

Edit: and because I expect LineageOS's wpa_supplicant is updated (against security flaws), contrary to the wpa_supplicant binary provided by Lenovo.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] abirkan:

Stable version coming? Or not?

Yes working but signal week ☹️
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] raphj:
Thanks for the work behind this ROM.

I dirty-flashed this rom from LineageOS 15.1 which has been rock solid for me.

Here are the issues I have seen in this new rom:

- as previously said, fingerprint gestures do not work yet. Fingerprint unlock work.

- I use extended desktop and fallback to the navbar:

- when the navbar is hidden (after being shown) and the keyboard enabled, there is a black area at the bottom of the screen / app that is the size of the navbar, defeating the purpose of hiding it.

- when the phone is in landscape mode, the navbar is often ususable: touching it anywhere only triggers the middle button.

Specific improvements I have seen:

- When using Open Camera, Camera API v2 seems to be used. I noticed because it was disabled and not enabling it leads to a black screen and black pictures when taking photos (is this a bug?).

- The minimum brightness has been decreased. A side effect of this is that when the set a a low level, the screen does not deem before turning off. I don't know if it is the case when the brightness is high.

- A regression for me that is probably a design choice from Google: it is now harder to see at a glance to which network the phone is connected or if the phone is hooked on the cell network / in emergency only because this piece of information apparently moved from the top-left corner of the status bar to the bottom of the notification area if unfolded. Unfortunately, I often am in buildings with spotty cell connection and I need to know when the phone is connected to send and receive texts / calls.

The rom is otherwise great.

I tried to dirty flash from Pie to Oreo (with the new TWRP) but this obviously results in a system that does not boot.*

I also tried to go back to Oreo using my backups, and restoring mms / sms by coping databases at /data/user_de/0/com.android.providers.telephony/ from Pie to Oreo, but this seems to make Oreo nut, so I'll stay on Pie and adapt.

Unfortunately, I don't have the the development skills nor time to help fix these issues. Thanks and good luck for the future developments! :)

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Since the beginning of LOS for this device I used F2fs and never backed down from it. No issues with updating not even with this new version updating is working without problems. So this would mean that the issue is not consistent.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
It would appear so and I agree. I'm sure it's something I've done that's caused the inconsistency.

The ROM itself it's very smooth and the battery performance seems great. 31 percent at the end of day two.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Ulysse 31:
Just upgrade from LOS 15.1 dirty flash, for now everything is great thanks a lot!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Just a hunch, is your phone encrypted? So I mean do you need to provide a code at boot? When I was at stock and my phone was encrypted the OTA failed..when I got rid of the encryption it worked flawlessly since then.

Is it possible to use it without magisk?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:

Boot into TWRP select install and navigate to where you've downloaded the update and install the zip.

Same OTA issue here

On los 15.1 with f2fs and encryption OTA was fine. no secure bootup (twrp password)

On los 16 with f2fs i get that error. At first secure boot was enabled, disabled it (reset the pin setup) and it stil does not work.

No big deal, just wanted to report.

The rest is flawless

In 3.2.3 it should not be anymore, but it is still in the compilation of the first post.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Akhil Lalji:
So here's my short review after 2 days of usage. I dirty flashed from 15.1 to 16, Flashed nano gapps, ext4 format

* Overall the UI scrolling has improved

* There's a significant increase in idle battery standby time. No overnight drains.

* But, the battery backup in general has decreased. While using the device, the battery seems to empty quickly. I'm attaching ss(moderate to heavy usage)

* Phone gets a little bit more warmer while gaming.

* FP reader has got faster.

* FP gestures doesn't work. But no big deal, I use the Android Pie gesture.

* No issues with fast charging.

* VoLTE works.

* Boot speed improved.

* App opening time improved.

* Overall the are minor stutters in the UI here and there. Don't know why. Sometimes(rarely) there's even lag in keyboard while typing.

* My Bluetooth earphones sometimes gets disconnected and connected randomly. (Had no issues with 15.1)

Overall a great daily driver.

Continuing the thread TWRP and OTA. In Lineage Downloader Premium, the update proceeds correctly.

With this feature you can hide an app from launcher and you can protect an app from unauthorized use.

You can access it by long pressing on home screen empty area. Select home settings> & Hidden & protected apps option.

Hey guys I'm facing an issue here please help me when I tried to install the 16.0 OS I faced an issue with the recovery after I have changed the filesystem of the data partition to ext4 I flashed os zip and the open gapps package but I found out that the package is corrupted somehow which led to me using the system without any gapps and downloading the package again through the jelly browser after downloading the package again I tried to wipe the system and do a clean installation again but I found out that there was an error while wiping the partition which led to stopping the process so I changed back the filesystem into f2fs which allowed me to install the os and the gapps but after that first reboot the device won't enter recovery again it stops on the splash screen and the LED lights blue with no action whatsoever please help me I'm using the TWRP official recovery from the official website 3.2.3 .0

I thought that Mike pointed to the same recovery that I have but it looks like I am using another version which is not lost compatible please attach a link to the right recovery which allow me to use OTA updates and flash magisk in the future

Also instructions to flash the new recovery and to get back to ext4 and cleasby somewhat simple and specific because I am not that professional thanks in advance and thank you Mike for your hard work the OS is very stable and snappy and bugs of 15.1 or not present here at least for me

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Crimson flamethrower:
do you mean that I need to have any version of TWRP installed to move to the unofficial lineage OS TWRP or can I download the IMG file and flash it as if it is a new recovery from ADB fastboot and please don't tell me that I need to go back to stock to reinstall TWRP again because I can't access any recovery at the moment it stops and black the screen out and prevent me from doing anything all I can do is restart the device
