So how to upgrade without data loss? flash rom and gapps and reboot?

Hi everyone. I hope not to be off-topic, but I have the following question. Is there any way of disabling the noise attenuation/removal feature when recording videos? I am currently using GCam and low sounds get completely removed, i.e. like if there would be total silence.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Erazor84:
Sorry for the probably "dumb" question ^^. But what does treble do to us in future? Does this mean, we will get Android P (LOS 16) right from the beginning? If not, what is treble exactly for? Sorry, but because i've never owned a treble supprted device before, i don't know much about it. And the pages i've found with google, didn't help me after all. Only thing i've figured out, is that it is easier for Vendors to release updates. So in this case - Vendor = Lineage or the Rom cooker (mike and highway? )

U need to flash a custom recovery (TWRP) first..U will find the procedures in XDA..then you can take back up of your existing stock /custom roms. And plz do google search why back up is needed
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mobnoob:
Thanks for the tips.

I do know why the backup is important that is why I'm asking for help :)

I'm confused because when dealing with TWRP's instructions I read that it's a good idea to backup before starting so I'm back to the loophole.

Is manual backup enough? I mean copying everything the computer browser shows about the phone or there are files and folders that are hidden because the phone is not rooted?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shabab malik:
If you have f2fs file system for data then Magisk couldn't let you install modules from within the apps. Change your file system for data to ext4. Make sure you backup everything from your storage.

It's a LineageOs 15.1 thread from next time please ask the questions related to the rom.

---------- Post added at 07:54 PM ---------- Previous post was at 07:53 PM ----------

Yes you are right. Currently Magisk couldn't let you install modules but root is fine.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] satej@123:
Thank God I did not change it to f2fs for little speed which would not make all that difference.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
we traced down the f2fs issue once and for all!

once it has been tested throughout. it will be merged and the f2fs code in the kernel will get an update too. making those little speed advantages, bigger.

we are pretty lucky on our P2 with the internal storage. its actually an hynix chip and a very well performing one if you compare it to other msm8953 devices. P2 outperforms them all.

This is great news ... So I'll stay on F2S and not use magisk modules for a while ?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] DarkHoundOne:
You can still install them, it's just that the install procedure is a bit tedious and doesn't seem to be very consistent.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] sunando:
By flashing it from twrp ??

Will it show up on the magisk manager ?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] DarkHoundOne:
Essentially yes, you'd have to flash the "F2FS Loopback Bug Workaround" module from magisk via recovery, then flash any of the other modules you want. Flashing them like this didn't always work and some modules didn't show up in magisk manager, which is why I called it an inconsistent method. Also note that clearing cache will remove all installed modules.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
this will probably never happen. lenovo simply removed to much from what's supposed to be there in the camera blobs and hacked too much around in the sources on its own which is useless for aosp.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] salim0786:
Hey,

Using this rom from the past two days.

I must say it's super stable and its just the initial release.

That said many features are missing like the circular battery icon,am/pm indicator, clock alignment.

Everything else is fine.

But I encountered a bug, Bluetooth calling doesn't work at all. It just throws back the call on phone earpiece. This happens sometimes on earphones too.

Then I have huge overnight drain. Its 6% overnight.

Network reception isn't great on oreo.

Hope these get fixed in the future release [MENTION=3839575]mikeioannina[/MENTION].

Thanks for los and bringing treble to our device.

Ps- not using magisk. Using f2fs data and official root addon

---------- Post added at 04:19 AM ---------- Previous post was at 04:16 AM ----------

Not great for me. Got 6% drain overnight. I'll let you know the sot tonight
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
A: as Mike already explained all those missing features you saw,used and loved in 14.1. will be back in upcoming releases. Oreo made it harder for coders to implement those features and developer's focused on the bring-up of their devices to Oreo first.

it doesn't help that Android P will break the code again and everything that will come back will have to be reworked again. Google doesn't make it harder for devs but rather difficult with every new major release.

B: it's a known issue. read A:

C: not an ROM issue. check your apps for wake locks. something is keeping your device awake and draining battery.

D: in Oreo the network reception signal calculational has been taken from CAF. and it's way off imho. Google uses a different SNR calculation. whether or not it gets implemented doesn't change anything in the reception itself. it will be exactly the same as if you had stock running. it's just the signal calculation and not the signal itself.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shabab malik:
There are few people who are complaining about overnight battery drain. There are no battery drain overnight. My battery backup look same like in lineage 14.1. Someday there are 1% battery drop overnight and someday 0%. I have 115 apps installed and Magisk.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Trance Paradox:
Dirty Flashing

I tried and got a weird bootloop. First it got stuck on the recovery page. The I wipedbthe system and cache then flashed it then it would boot. But after a few minutes or so I would shut down while the screen is off and give a blue notification light. So then I wiped system, data and cache and now it works fine.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
I believe that not all P2a42's have Hynix memory chips. I'm pretty sure that my previous P2 had Samsung memory chips (RAM, Flash) inside because I've checked it in bootloader mode someday. When I bought my current P2 and restarted it to bootloader I was like "Hey, this device has different memory than my previous one. Will it perform worse, better or maybe as good as Samsung's one?"

I might be wrong and what I remeber is just vision created by my imagination but I believe it's not. I don't have any evidence right now but I will try to find it and tell you if you're interested in that one too.

- First P2 was brought in official Lenovo reseller shop (x-kom) - Came with 6.0.1 preinstalled, P/N: PA4N0018PL

- Second P2 was brought in casual customer electronics market (euro rtv agd) - Came with 7.0 preinstalled, P/N: PA4N0123PL

Both purchased in Poland, even in the same Mall

something is very wrong......

First if I flash lineage then any other gsi like pixel experience, it gives me decryption unsuccessful error.... I'm not even able to format the storage to remove encryption. I did format the encryption using an older version of twrp as the twrp provided for treble gives an error like ''

Unable to format data. Unble to remove encryption

-Now When I formatted data using earlier twrp and hen flashed the treble one and then flashed lineage. Booted and it still encrypted my phone. So the loop goes on again.

I dont know whats wrong. Treble flashing should be easy... been awake since last night trying to make it ork by using different combinations but no luck.

can anyone help?

Thank you [MENTION=3839575]mikeioannina[/MENTION] for the new ROM.

Runs smooth as my daily driver.

One thing:

Am I the only one experiencing notification-problems with WhatsApp?

Scenario:

Doesn't matter if on WiFi or Mobile Data - after not using my phone for ~15 minutes and longer I won't get notificated by WhatsApp in case of new messages.

If I then open WhatsApp manually after some hours, I get all the messages.

I didn't change anything in the settings from 14.1 to 15.1 and of course followed the official way to upgrade.

I don't use GAPPS or Magisk or other fancy stuff and WhatsApp is up to date.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
unfortunately you won't be able to just update.

the /data partition needs to be formated with a different version of mkfs.f2fs which is not backward compatible to older f2fs partition.

mike or me will probably post a guide or the wiki will be updated for the procedure. there is still some testing to be done. we don't know yet if it will end up on the next tuesday build or the week after. we want to be 100% sure that we caught everything there possible can be. before pushing it out.

keep in mind Official Lineage is all about quality and stability. we don't want you to end up in bootloops.

Ext4 data. I had a lot of problems running f2fs even without magisk, after reboot it wouldn't decrypt nor format or mount. I had to flash latest official TWRP to perform data wipe, then flash LOS TWRP to install rom. I'm waiting for update to check f2fs data performance on Samsung memory.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
It would be nice If some people will do memory benchmark using same, next nightly f2fs fixed LOS 15.1 build.

Let's say that requirements are:

- Clean, freshly installed LOS 15.1 with F2FS data partition (As [MENTION=2494638]celoxocis[/MENTION] said, in next build mkfs.f2fs is not compatible with current version so you will need to format your data anyway)

- Same pack of gapps (opengapps nano/pico/etc. or mindgapps)

- No google account configured yet (to prevent phone from downloading data and configurations from your account during doing tests)

- No apps installed except benchmarks required for testing

- Same benchmark app, let's say AndroBench (You can download it right from ApkMirror)

Just out of curiosity.

so, one of the next builds, force us to format data? or is this just needed if you wanna use magisk? sorry for that question, but i've read every page, but i better ask, to be sure hahaha. because i never wanna use magisk, or another root method and i am using f2fs r/n without any problems (formated with the last lineage TWRP - the 14.1 one)

i don't really wanna loose everything and redo it from scratch, because i've never encountered a single problem as "normal" rootless user haha, but if it is needed, i guess we have to do it :D but to prepare myself (remove steam auth. - or else i lock myself out of my steam account again and other authentificators) also - redo everything, prevents me to use the steam community market for 14 days. that would be annoying, but if it is nessesary ... greetings
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
NO! will never happen. ext4 is superior in access times which is mandatory for /system. it is read only. you will never have random writes on /system. where f2fs shows it's advantages.

---------- Post added at 06:16 PM ---------- Previous post was at 06:11 PM ----------

if you are on ext4 you can simply upgrade the ROM.

but if you want f2fs without any issues you will have to erase userdata and run through initial setup.

but if you know how to work with TitaniumBackup. you can simply create a backup and flash all your apps+data through TWRP and you have everything in place again.

search the forum. there are countless guides on Titanium Backup.

rule of thumb.

you should always update to the latest available stock before switching from stock. in our case S251. reason being the compatibility, LOS is ensured to work with the S251 radio image. should the S244 radio image be different from the S251 you could run into problems.
