Not sure if anyone had spotted this, but LOS 16 has rolled out for a few devices. Not ours at the moment.

Our 15.1 updates have moved back to weekly now too.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
It's advised to upgrade to the latest stock version via OTA before switching to any custom rom.

[MENTION=3839575]mikeioannina[/MENTION] sorry if that question has been already answered, but will it be possible, to simply "upgrade" to 16.0, when it arrives, when i am already using EXT4 for data partions? back in july, when you have released the 15.1 build, i did a complete clean install, instead of just upgrading from 14.1 to 15.1. and i formatted data to ext4.

or because of the changes you've made, we all need to make a full wipe of everything, no matter what file system data is using?

greetings and thx for supporting our beloved device! ;)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] isomerasi:
thank you, i'll do this...
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] prashu199:
I was on 15.1 ext4 already.So i just upgraded my recovery and did a clean install of 16.0 after wiping data system cache.There was no problem. ?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
yes, but my question is, if we are be able to upgrade WITHOUT wiping data, when data is already ext4, due to the stupid lenovo kernel f2fs bug ;) like we were be able to simply upgrade from 14.1 to 15.1 without wiping data, only system and cache, so every app is still installed and there. like steam and authentification apps.

in my case, with 29 accounts and 29 unifying 2factor account protection codes over my authentificator app, it would be a pain in the ****, if we could not keep data hahaha. (root is no option, so titanium backup also not)

also steam would be "blocked" for 2 weeks for the steam community store (everytime you change the authentificator to another device / os) ...

so if we MUST clean install, without be able to keep all installed programs / settings, i will stick with 15.1 for a couple more months i guess. to disable 29 2factor accounts and reinstall them one by one lol. i dont know hahaha
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] prashu199:

My phone pe app transactions have stopped because it detects that my device is rooted. A week before it was working fine with the option of Magisk Hide in Magisk but now it appears that the latest version of Phone Pe are able to bypass that and detect root presence. I am on latest Magisk version. ANy help?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Camack:
I have the P2C72 (4/64GB Chinese version) with stock S244 ROM but there are no more updates and GCam doesn't work properly so I would like to flash this ROM but I have a few questions that I would like to ask before flashing and please forgive me if they have been asked before.

1. Is the ROM stable and can be used as daily driver?

2. Which nightly version should I flash that is the most stable?

3. Are there any bugs/something doesn't work or is everything working like stock ROM?

4. I'm currently on stock S244 ROM with TWRP and Magisk installed and in the OP, it says recommended ROM firmware S251 so is it best for me to fastboot flash back the stock S244 ROM and OTA update to S251 first before installing LOS?

Thank you
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Jerghal:
This LOS ROM is only for the P2a42 version of the phone. I wouldn't install it on your P2c72, as it will probably will not work correctly (or not at all).
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
Yes, you will be able to do that if you're on ext4 without problems. People on F2FS will need to backup their data and restore after repartitioning with new build of TWRP. The one thing is: If you're coming from official 15.1 then you need to wait for official 16 to upgrade it properly. Check his profile for latest posts as he posted here about it before.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] hnsaba:
You can use it on P2C72 without any problem. The ROM is far better than stock. Do not waste even one more minutes with stock.

Please do NOT give incorrect info. ROM is fully compatible with P2C72 as it is the same as P2a42 with minor differences.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
Yes it's true P2C72 users can use the official ROM without any issues.

In the very beginning we did not have any dev or contributor that had an P2C72. So we added disclaimers to use the ROM only on the P2a42 to prevent possible bricks for P2C72 users. Those disclaimers are probably still around the forum which probably lead users to confusion.

Our beloved highwaystar who brought you Google Camera support for the P2 has an P2C72 and back then was able to verify it works flawless on the P2C72. He even made his GCam hacks/fixes by using his P2C72.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Rockarolla1:
My phone is P2C72 too, and i can install any rom and mods without problem! Just flashed global version before that!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lavesh05:
i am on latest 15.1. i have lost fp gestures and fingerprint. there is no option to set fingerprint in security settings. i read somewhere to delete this file "settings_fingerprint. xml" from root storage data/system/users/0. but i found that this specific file is missing from my phone. so can anyone copy this file from their phone and send me so it might solve my problem or please tell me any other solution. i get this error "fp hardware not available"
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Camack:
Thank you for confirming that this ROM works on P2C72, is the battery life/SOT better than stock?

Also last question before I flash, I'm currently on stock S244 ROM with TWRP and Magisk installed and in the OP, it says recommended ROM firmware S251 so is it best for me to fastboot flash back the stock S244 ROM and OTA update to S251 first before installing LOS?

yes

yes please copy this file and send me on gmail id- lavesh05@gmail.com
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
I am not sure if it will work correctly, because old TWRP had bugs in ext4 format code as well, not reserving crypto footer properly.

I might be getting a replacement screen for my first kuntao in the next months now that they became cheap so I can test more stuff without messing my daily driver kuntao. Official 16.0 has been released for other devices and it will be soon available for kuntao, I just want to refactor how fp gestures are handled because there are a few bugs at the moment and the implementation is not so treble compatible.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
thx for your answer! probably i am not affected. i don't know exactly what the bug caused with ext4, but every update went absolutely perfectly so far (updater download - auto reboot - decryption) never experienced any problem.

last week i have flashed the "new" twrp, you've postet some weeks ago. we will see how it goes when the next weekly 15.1 update is coming on sunday. but

- fingers crossed - that i can simply upgrade to 16, when it arrives :D

at least i think, if the next 15.1 weekly can be installed correctly by the "new" 16.0 compatible twrp, it could handle the ugrade too.

if not, it's ok. it's just annoying to cancel all 2factor accounts and reregister them again ... good for the safety, but hell of annoying hahaha. especially steam, which "bans" you for 2 weeks, when you're changing your device / app / os whatsoever.

thx for your reply!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Tahir Baig:
Thank you very much.

You've got mail;)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] hnsaba:
Thanks for all your attempts.

Michael, since the kernel 4.x is released for Xiaomi mi A1, which utilizes the same SD625 as our kuntao, is it possible to have it running our devices?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] DS-1:
Where did you find a cheap screen replacement?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
Let us know if the new twrp (this one I guess ) has problems with the next LOS 15.1 weekly release.

I'm using LOS 15.1 with ext4 filesystem format, too. I changed filesystem from f2fs 1.5 years ago I think. In case we need to format again with to the new twrp should we disable fingerprint authentication?

Thank you.

---------- Post added at 10:55 AM ---------- Previous post was at 10:47 AM ----------

Thank you again for the great work. Just to be clear: will you wait until the replacement screen arrives (a few months, if I'm not wrong) or LOS 16.0 official for kuntao will be released befor you get the new screen?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
my bet and probably cheapest source would be taobao.

https://www.google.com/search?q=p2c72+site:*.taobao.com

that's where I got my genuine replacement part for the small part that contains the charging port and vibration motor from. I haven't swapped it yet though.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lither:
I'm on stock S251 with Magisk and would like to install the latest LOS 15.1 and I read that I need to use two versions of TWRP (official TWRP to format data and LOS TWRP to flash the ROM, GApps and Magisk), is this still needed or is there a TWRP that can do both?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
if you never changed /data to ext4 from stock f2fs. you don't need to.

if you happen to have changed /data from stock f2fs to ext4 and want to get it properly booting into los 15.1 using f2fs. you will have to. just check my post on page 25 on how to do it.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lither:
My P2 is the Chinese version so I fastboot flashed the stock P2A42 firmware from this thread and haven't changed the file system so it is stock f2fs.

Which file system is the best to use in LOS 15.1 with Magisk, ext4 or f2fs?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
I prefer f2fs. Just seems a little more responsive. Are you planning on using magisk mods? If your are and you use f2fs you'll need to use the workaround found in magisk downloads
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lither:
Yes, I will be using Dolby Atmos and Youtube Vanced module in Magisk, do you have a guide/tutorial on the Magisk workaround?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
It's all in the description of the mod
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Camack:
I'm in the same position as [MENTION=4663690]Lither[/MENTION], which F2FS module version and Magisk version are you using?

Did you delete AudioFX in system app before flashing Dolby Atmos?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] kamran15:
It is not necessary but if you want to remove you can do it

And use dolby as your system equalizer
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
I'm using magisk 18.1.

I actually use a different workaround for the f2fs mods issues which is a little more complicated, but works better I've found. Link below to thread.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Crimson flamethrower:
Hey guys I have installed this OS over my stuck OS and it feels Stable so far but the only bugs I am facing right now are the Bluetooth in band ringing is not working probably it is not sending the ringtone to the headphone and I worked around this by removing the Google phone app installed by the g apps package and using the stock dialler app then all the other apps for calling or not sending a ringtone to my headphones and there they don't ring the device so it is rendered silent when someone tries to reach me through a calling app except the official osp dialler app the other bug is that there is no battery low alert so I'm surprised every time my phone gets at 1% and shuts down without knowing it keep in mind that im using talkback so I am not always checking for the battery .

I would love to add that I am installing the updates over to my device using the official TWRP recovery by wiping the system partition and the cache partition and installing the new update image without using the lol recovery will that be good for the 16 build

Additional info it is a clean install and there is no root access no su or magisk and the gapps variant is stock

Is it the method of removing the active chip of the sim card ?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lyceus:

I just flashed today's 20190310 build and my SIM isn't working. I've always had this issue where I had to activate airplane mode to get the SIM PIN prompt after boooting up the phone, but now this isn't helping either.

Any suggestions? I'll try going back to 20190303 meanwhile.

Never mind. I just downloaded and flashed today's build again. Works now. No idea what went wrong :confused:
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
[MENTION=4857397]nihil39[/MENTION] I've just updated to the latest 15.1 update - with the LoS 16 compatible TWRP - went absolutely perfect.

Updater App inside of LoS15.1 - Auto Reboot - Partition unlock and flashing - everything worked as expected!

it was be able to handle my in july 2018 formatted ext4 partition without any problems!

so i guess, a simple upgrade to 16 should work without any problems too! :)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Probably a stupid Question but does anyone know how to assign a Sim card to your work profile and the other to your personal profile. This to be able to use separate ringtones and notifications.

Basically I want to determine which Sim receives a call based on the ringtone. I see the option but it does not work...
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nothingman1976:

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
Yes on 15.1. I think that option becomes available when using 2 Sims and a work profile is being created due to device policy.

---------- Post added at 10:44 PM ---------- Previous post was at 10:38 PM ----------

I carefully removed the chip from the plastic holder. Then I sticked it with double-sided tape to the sd-card first to test. It worked. Then I glued it permanently to the SD card. ( If you're Sim is getting faulty overtime, you can remove the glue with heat).

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] :
Hello mike during my 16.0 usage period i stuck up with ring volume & media volume bug after clean installating twice though. The bug i explain earlier in 2 posts. I missed some calls even while listening music on earphones while on vibrant mode!

Did you fix it the recent developments?

Also the Pie navigation gestures was missing.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] tanzeel.ahmed1306:
Pie Navigation gestures were present you had to enable them from Settings>System>gestures>swipe up gestures..

then enable navigation bar and you have your pie navigation gestures
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] :
As of i remember there was one Jump to camera gesture available, i rolled back to 15.1 after 3-4 days of usage

EDIT: there was no "one jump to camera" gesture available.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
I formatted to ext4 in 2017 and it works well for me, too: I flashed the latest twrp and the latest 15.1.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
yeah, i don't know if i formatted with that 14.1 TWRP, or with the "newer" 15.1 trebble enabled TWRP. but i guess, our devices are not affected with that specific ext4 bug. so we can hope, that a simple upgrade to 16 will work as the normal 15.1 updates.

if our device would have a faulty "bug" ext4 parititon, the newer 16.0 twrp would have problems with it, even with 15.1 updates. but because it can handle the updates just fine, i guess we are safe to upgrade. at least i hope so. never had any issues with my file system or upgrades since LoS 14.1.

I always updating over the - updater app inside of lineage OS - the OS prepares the update, autoboots into TWRP and done.

but i also don't use root or magisk. probably that's why we are "safe" from bugs.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
I hope so, too, but frankly I wouldn't mind to format again in ext 4. I just hope the instructions are clearly written and I will make a backup of any document on the phone without any problem.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
back in july, when i upgraded from 14.1 to 15.1 it was a simple task - just format system, cache, flash new LoS & Gapps (if needed) and woala - everything is the same as on the old OS. every app and setting was transferred.

but to do a backup with TWRP, is always recommended. i will do that too, before i flash the new one, when 16.0 comes out

Did you also get this problem in LOS 16.0 build by mike?

This problem only gets solved by rebooting the phone also it comes back again after sometime of usage.

Official doesn't mean this proximity & earpiece volume cracking will be solved untill the dev push some fixes.

I'm using newest 16 from it's early days as well and didn't notice any problems, calls were all fine, even after messing with viper, dolby and patches. Flashed cleanly couple of times because of testing and it was right every time. Battery is also great, the best all of all roms I've tried, crDroid had I feel better performance, but the battery drains twice as fast. The only issue I had wasn't with the rom itself, but with the twrp, sideload doesn't seem to work and I need to swap to original one for flashing, then replace it with Mike's version.

Bro from what i figured out is that rom has some problem with headset plug/unpluging bug, it doesnt figures out the status of headset plugged thus those issue occurs.

Hi!

Thanks in advance and congratulations for your work in this ROM.

I have installed several times this ROM (15.1) without gapps or anything else and starting it I always have an automatic connection to this IP 130.88.248.255 that owns to man(manchester).ac.uk.

[MENTION=3839575]mikeioannina[/MENTION] please, would you tell me where I have to look for in order to disable it? If I block it with a firewall it does not work because it bypasses the restriction.
