I do it directly from the settings-> LineageOS Updates

It has never caused any bootloops for me till now
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] kleankutrockstar:
After downloading the update file my P2 reboots to recovery and dirty flashes the update file automatically.. This is how the device applies the ota update from the system LineageOS updater.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mrmahi42:
Only thing you can do is dirty flash via twrp. I had the same issue but this trick worked for me
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Hi all

For me is the same issue. Updating by OTA.

I don't have Root. Followed all the steps in the wiki. Still getting the download corruption message during update.

I even flashed everything back to stock ( recommended stock build s251 if I recall it correct) and started all over from build 1. I've used gapps micro, nano and pico. Does not make a difference. I switched on zip signature verification in TWRP during manual flash and in the 2nd and 3rd build both gave the message zip verification failed. I downloaded the updates also before manual flash 3 times and did not help.

So the issue should be somewhere else.

The updates did perform well manually though like [MENTION=2494638]celoxocis[/MENTION] already mentioned in an early post. So can this be a bug?

I think airplane mode big still exist. I have 2 sim cards, when I turned on airplane mode, and turn it off, my phone can't detect one of my sim cards. In the phone setting, it said "slot 2 empty". had to restart my phone to make it work again.

Try disabling play store, then reenable it and do a reboot. This sometimes work, It's worth a try.

My device also says uncertified and I also don't have root. but I don't experience any issues with it.

As long it does not affect the functionality it doesn't bother me.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] abdal2006:
Yep, I too don't have any problem. But I would like to see it as cerified.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Agreed, just did some tests like in the previous post.

Stopped Google play

Then disable Google play

Deleted cache

Then deleted dalviks cache

Booted phone

Enabled Google play ( no message so far)

Now I am rebooting my phone.

Edit: after reboot still no message about certification. Section is not there. I'll pay attention to it.

Edit 2: still not certified...

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shailuk301:
Then root using magisk.

It might happen that magisk safeytnet pass might help you.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
I don't use magisk, and i do not want root. Any other suggestions?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] abdal2006:
Yes, I too don't want to use root.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Well just ran a safetynet test and my CTS profile does not match. I don't have root and also no Magisk. I think this is the root cause of the certification issue.

I thought that LOS was an certified custom ROM...
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shail00:
If I select internal storage as well while wiping, does that mean that the recovery will also be deleted?

I wiped dlavik cache, cache, data and system and after the side loading ROM, the internal storage still stands at 15 GB consumed. I need it like stock...please help in internal storage case
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
No if you wipe internal storage you don't wipe the recovery.

You need to wipe the partitions(cache, dalvik etc) then sideload the ROM instead the other way around.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shail00:
I wiped both cache, system and data but still old folders exists.

Any help?/or should i wipe the internal storage as well?

Is there any side effect of wiping internal storage?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Internal storage is app settings personal data like pictures etc
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shail00:
I dont care abt personal data, and rest stuff, i have a backup of those.i think i shoukd go with wiping internal storage which i did not perform last time.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
A general question to everyone.

Are there people in this thread that has LOS installed, have an certified Play Store, no root and have an CTS profile match (during safetynet test).

Thanks in advance.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] asraf5285:

I can say that substratum swift black theme working on official version very well but I installed it with root.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] abdal2006:
Bro, I have only one doubt, in official los 14.1, substratum theme engine works with out root or not.

Is rooting necessary for los 14.1 to use substartum theme engine?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Liacon:
You need superuser for use substratum, so, yes, you need to root
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] veimus:

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
As far as I know this ROM is only supporting A42. The noticeable differences is the memory.

I know it is an China version. Difference between NFC controller is not known by me.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Billytromp:
Thanks to all the contributors for this amazing ROM which does our wonderful peace of equipment more than justice. I've been using it for several days now, haven't encountered any devastating bugs, and battery life is very, very good(using Greenify with root).

My only gripes with it:

- Bug or not? The call volume can not be adjusted enough, hence sometimes still being to soft at max. or to loud at min.(I've very sensitive ears:)). The slider also can't go any lower than approx. 20%. does someone know how to modify this in some file?

- Like mentioned here earlier, I also notice that the phone signal often drops for some seconds, and I think it's not just the icon showing this as the call quality seems to be fluctuating correspondingly

- Mentioned before: Bluetooth shows up in the charts as a sucker, but actually is not
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] jaks218:
Try this to improve loudness

you will have to wipe the unofficial version and do fresh install of the official build. it'll work after this. try doing a titanium backup and then wipe and install.

There is a post from [MENTION=2494638]celoxocis[/MENTION] what to do when coming from unofficial to official. If I remembered correctly. It had to do with f2fs format. Which is different inn the unofficial build.

You have to perform a full wipe ( Dalvik, cache, system, data/ internal storage ( you'll Lois picture's etc) format the data partition to ext4, reboot in recovery, format to f2fs, reboot again into recovery. Then flash ROM + gapps without reboot in between from external SD-Card.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] :
Uncertified causes nothing Google will still let you download all apps, it's just new scheme for the OEMs but Google still recognises LOS, AOSPs etc ROMs & let us download apps.

Uncertified only tells the ROMs were are using didn't go thru Google OEMs approval procedure. It won't hurt.

unless you have to satisfy your mind with certified tag that too with Root LoL :D which itself isn't secure.

Hey guys, I had the unofficial LineageOS 14.1 build running just fine on this P2A42. Had to wipe and reinstall TWRP (on 3.2.1-0 now) and tried both the offical 14.1 build and the 15.1 preview floating around here. Both get me a bootloop (with/without addonsu or Google apps installed...). Does anyone know how to fix this? /data is formatted ext4 and I've wiped/reformatted all partitions (/system, /data, /cache etc.) but no dice....

Thanks!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
The problem is in the filesystem on your phone. When you come from an unofficial build you need to reformat them into the default filesystems.

All partitions have EXT4 except /data (F2FS).

See also a previous from [MENTION=2494638]celoxocis[/MENTION], it is basically the same issue, if you follow the following steps it should work.

if current filesystem is f2fs then:

format /data to ext4

reboot into recovery

format to f2fs

reboot into recovery

confirm /data is mounted and f2fs

then perfom a wipe and reboot again in recovery

confirm if all partitions have the proper filestystems all, ext4 and data f2fs

then flash the rom.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] .:B:.:
