And it worked! I downloaded the latest nightly with the updater, but then I flashed the zip manually in TRWP instead than "installing" it from the updater. Flashed Magisk on top, and rebooted. All nice and smooth this time :)

I cant update via OTA. I tried three times , all three times downloaded the build but the error Zip is corrupt comes(screenshot). I downloaded these from different networks and all continuous without any resume, so how can the zip be corrupt.

I dont want to do a clean install bcoz again adding acc, apps is big task and wastage of bandwidth.

My data file system is f2fs with no workaround.

No magsik installed , no modules

Can anyone help ??
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shabab malik:
The zip file you have downloaded is corrupt. I recommend you to download the update again.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Armaty:
okk I am trying again

---------- Post added at 07:37 AM ---------- Previous post was at 06:59 AM ----------

Well again that error zip file is corrupt came..!!!

But strange thing happened , I exported that update to my internal storage and manually in twrp flashed it and guess what it flashed with no error.

Means how can that be possible in OTA it says zip is corrupt and manually it works fine
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:

I've had this issue also couple months ago, i didn't came from s251 as described in requirements. I did also not passed the safenet safety check.

Therefore I started all over again. Then I flashed this ROM (from 1st build) including TWRP (version as described on LOS page). Also Magisk to pass safenet and gapps. Now everything works like a charm. Including OTA.

I flashed twrp from its official app. I can see both version of official one and the one provided in link are same. Is twrp causing this issue ?

I hv f2fs with no workaround , is tht causing it ?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] DarkHoundOne:
Updated via OTA a few hours after the weekly update rolled out, ended up with the phone being stuck on the Lenovo logo. Had to wipe everything and reflash the latest build and gapps.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] philje123:

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] ArnavxD:
Hey folks new here. Can you just shortly how is this ROM ? Just these questions

1. Battery SOT?

2. VoLTE, GPS, FP & Fast Charging working properly?

3. Any Gaming Lags or Heating Isuue? ( I Play PUBG)

4. Common Bugs / Stability.

5. Finally, Better Than Stock?(I'm on S251)

Please reply. Thanks.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] P2.nl:
LoS 14.1 is better then stock.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] lozohcum:
1. Worse than on Stock but it's not awful.

2. I use everything except VoLTE, I can confirm these things are working well on daily basis.

3. I don't play games but overall performance is very good. There is only 1 issue with Chrome, sometimes it freezes for like 1-3 seconds.

4. Signal indicator keeps going back and forth, but it's only indicator. The connection itself is working ok all the time.

5. Depends on your expectations. I installed Lineage because on Stock soundClound and navigation stopped working and nothing helped with that untill I installed Lineage.

I see almost no difference between this and stock. Lineage gives you some more options to personalize the system. I have constant problem with facebook messenger, it says that there is no connection while all other apps are working fine with network. (probably caused by adblocker, I'm investigating )
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
1. So much better than Stock.

2. No VoLTE (my provider does not have it - only LTE Data)

3. Better framerate than on Stock, especially with games like Pubg

4. No Problems, no difference to stock
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Uniposka:
Yeah, it seems that flashing manually with TWRP is the way to go to avoid any troubles. However, I still like the OTA updater for the notifications and for downloading the zip files directly. Not too bad ;)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] anilyarki:
1. Battery life is awesome. Usually getting 12hrs of SOT with 4g data on all the time.

2. Volte - GPS - FP gestures - fast charging all working perfectly fine.

3. No gaming lags found so far. I have Call of Duty installed and playing well. Even the lag in instagram with official S251 is gone.

4. One small bug i encountered a few times is temporary loss of Network Signal after a long call. But it returns after a few seconds.

5. Definitely better then stock. Go for it.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Armaty:
yeah! it works but but after all its a dirty flash. It works fine now but in future it will cause problem i guess
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
stay curious for what LOS 15.1 will bring.

mike has kanged 95% of the blobs used for kuntao's LOS 15.1 from Oreo based ROMs. so we can expect some improvements.

kuntao on almost pure Oreo binarys is an amazing accomplishment, something Lenovo will never give us but is well deserved for such an underestimated device!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fullbustah:
For all non-believers here is proof that Mike is working hard on los15.1. Working los15.1 build based on his kernel source. Didn't find any bugs so far.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fullbustah:
It's my personal build and please don't ask for download link. Wait for official build by Mike. There is a reason why it's still staging branch.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
it has been explained extensively in a previous post.

if you care about it. feel free to gift your P2 to the original russian dev who ported the gcam mod to make it work and fix any issues.

---------- Post added at 08:30 ---------- Previous post was at 08:15 ----------

that's right. mike doesn't just kang some random custom kernel. he takes the latest vendor platform kernel from CAF (see msm8953_64 Oreo)

https://wiki.codeaurora.org/xwiki/bin/QAEP/release

and merges the useful parts, from the latest available Lenovo Vendor Kernel from P2 (in our case Nougat), (which are drivers, hals,etc) adds countless approved backported fixes from codeaurora (and even some from Sultan) on top of the CAF code.

it's called "rebasing the kernel".

guess what, its something vendor devs almost never do. because it's time consuming (time is money) and requires advanced kernel knowledge, which a lot of vendor devs simply lack.

OnePlus for example is an exception.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
sometime this year.

if you can't wait I suggest you buy an Google Pixel phone and donate your P2 to an developer that sacrifices his free time to focus work on qualitative development over rushing and craming things together that results in errors and lower quality work.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
I've been still using P2 daily on 15.1. It should be ready, except I still didn't find time to try a clean install to check for potential issues after all the blob updates. I am also having an issue where my device doesn't charge when screen turns off, but still looking if it's a generic problem or this device is dying as well.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] medwatt:
Can you please try face unlock on your device ? Currently, face unlock fails to unlock about 80-90 % of the time in all the Oreo ROMs available for the P2 so far that I've tested. However, this was not the case with LOS 14.1, where face unlock worked flawlessly. Please do me/us a favour and check on your device.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] 911-Future_Maker:
Enable treble please, live display is not even an issue.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fullbustah:
It's probably generic problem I experienced this issue as well, but thought it's some built-in overcharge protection. Also face unlock probably doesn't work, tried different gapps and magisk module, but 0% success with face recognition.

Fingerprint sensor not working

hi all

Since yesterday the fingerprint has stopped working not an hardware as I can use it as a home button ! Also noticed that the option of fingerprint is vanished from the security option !! Any help ?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] 911-Future_Maker:
Live display the option that adjusts screen color under day/night conditions. That's not important to me.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
Did someone (mike) ever write that live display is not working?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fullbustah:
Yes, he mentioned it here.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nothingman1976:
He said that treble broke fingerprint and livedisplay and for these reasons it's not enabled right now...
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
Oh, ok. I need night mode (mike wrote that treble broke some live display options, I don't know what they are), it really makes a difference if you're reading before sleeping. In general it's better to have a stable and working rom than having treble, in my opinion. Fingerprint gestures are another useful feature.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] :
Please get over with this cringe. Mike already explained situation about treble for this device & the bugs he faced.

Our device has only 1 partition, but 2 are required.

Back to the Treble thing, even if he enables it somehow, the harware drivers won't works for future android versions, devs need to again modify to make them compatible with future versions. There is no need to place hal vendors in seperate partition when you have to mess with the hal all over again becauee they won't work with future versions.

Treble is just a concept at its beginning. Let OEMs develop universal hals which would be compatible with different android versions.

Working fix for dark video & video playback issues on Lenovo P2 custom ROM

Download and flash the zip file downloaded from the link above in custom recovery (TWRP) and reboot your phone.

Method 2

Add the following 2 lines at the end in your build.prop file (found in Root>System>build.prop in your file explorer like ES File Explorer/ Solid File Explorer, remember to check the "Show Hidden Files" to view Root Directory)

Known issues on my P2

Hi dude, thanks for you rom at first, it's the only one supports ota and fingerprint so far,

I believe the recent 15.Jun rom is a very "radical" one, especially in the bandwidth part, I met some issues with my p2,

1. This rom supports cdma2000 3g bandwidth for the first time, although the signal is unstable, it's great work.

2. Both of my dual sims (lte, wcdma and gsm supported) have signal icons on the status bar, but only one of them can make call or receive sms in the same time, it never happened in your former roms.

3. The battery stand by time of this version is much shorter than past roms, and the temperature of my p2 comes hot very often.

4. Although I have successfully updated to the latest 15.Jul version, the system updater keeps show me notification of new update, but it's just the same 15.Jul edition I just installed! I tried to re-download the rom again, but the system updater always crash when I click "update" after full downloading. I also downloaded the 15.Jun rom from your website, and reinstalled it with the latest recovery after cache and data sweep up again and again, but nothing changes.

Regards,
