[ROM][prague][11] LineageOS 18.1 for Huawei P8 Lite 2017

[SquallDNA]

Tu es sur que c'est la 383 que tu télécharges, normalement il télécharge la dernière version si tu passes par le e-recovery et la dernière en France c'est la 408

Im pretty sure yes. I will attach a screenshot of the phone later. This is again a different variant of the P8 lite 2017, named GR3 2017, from the Philippines. Maybe that's the reason why it has its latest firmware on .383.


UPDATE:
I have attached screenshot of my GR3 2017s firmware version.

In my case I got the 410.... strange
Will follow the instruction @AltairFR gave me, and let you know if I manage to install.

I tried to install ASOP 11 by Darkjoker360. And i managed to run it. But i bricked it again.. please tell me if you do install lineage, and how you did it.

Yes. Im also having difficulty finding stock rom and guide for this specific device.

I did it! I downgraded my firmware from a nova lite using dload method. Flashed and it worked. However, i still cant use Volte. If i search on the settings there are the options to set VOLTE. But when i click it, it just sends me to the mobile network settings without any Volte options or toggle. I already used the fix on 2nd post. I tried to use ×#×#4636#×#× but the VOLTE PROVISION is greyed out and cant be toggled. I really need to make volte work.

Well done May I know what you did after getting the rom?
Because in my case I found an older rom, uncompressed it, copied the dload directory to SD,
then I rebooted phone with vol up and down, but the phone refused to flash it..
As this is a previous version I wonder if the phone is refusing to downgrade through this method..
Did you do the same or used another method to downgrade your phone?

Yes i did the same procedure. Mine actually flashed with no problem.. make sure it's just the UPDATE.APP inside the dload folder. Mine flashed even thought im from GR3 2017 8.0.0.383 to NOVA LITE 8.0.0.360.

What's interesting is i did try to downgrade using 2 different stock fw, NOVALITE and P8 LiTE 2017.both flashed with no issue. After installing the P8 LITE though, my firmware still shows that its a Nova lite..

Thanks will retry. How did you get your p8 lite 2017 ROM?

You can search for different variant. Goodluck.

Done! seems like my sd was badly inserted the first time, and phone wasn't seeing it hence update failure.
Restarted and phone smoothly downgraded (version 401).
After redoing all steps (BL unlocking, TWRP, decrypt...) and some suspense... custom rom flashed!

I'm glad this is finally done and I don't have to repeat this process anymore (my 4G mobile plan was fully eaten btw !)
et encore merci pour l'aide

Is there any newb-friendly solution for the FAILED (remote: 'sparse flash write failure')?
I'm new to custom ROMs and decided to test on this smartphone before moving to other ones.
It would be good if someone could resume every step into a single post.

the volt does not work on this ROM, on none besides

Je vous en prie

Unfortunately you'll have to read though our conversation. I believe we have the same error. The gist is that you should be in the right stock firmware version when flashing. The lower the better i guess.. In my case that's 8.0.0.364. Check the link above.

That's unfortunate. But thanks anyway.

OK, thank you anyway!

I seem to have found an issue no one else has reported, or is it somehow related to just my device?

Essentially this seems to be a an issue on the software side. When shooting videos in Snapchat app the audio that it captures is kind of muffled and distorted (bitcrushed to be more specific, it has this kind of ringing tone and extra noise to it) and it seems to be present only with Snapchat. When recording audio with the stock Recorder app or shooting a video with the default camera app the audio is absolutely fine.

Steps to reproduce the problem: Literally just record a video with Snapchat.

Right, to come back to my previous issue since noone has mentioned anything similar.

The issue seems to be with third party apps accessing the camera/microphone - I just realized the same issue occurs not only with Snapchat but when making a story on Instagram/FB, recording a video through Twitter and I assume whatever other third party app like this.

Microphone in calls and default camera app work just fine.

So, can someone please confirm if this is just me or wtf is this? Or is this something I can mess with in the settings? Clearly makes the ROM almost unusable or at the very least very scuffed from certain aspects.

I've attached two videos to more clearly point out what I mean, one taken in Snapchat, where you can clearly distinguish the distorted crunchy ringing sound and overall muffled sound.

Here's the same thing but taken in the default camera app on the same ROM and where you can hear that the recorded audio is clear.

Delete please

 

[Corrreia]

OK, thank you anyway!

OK, I managed to install the custom ROM, now I have a question.
How do I root the device? xD

 

[AltairFR]

you got the wrong ROM if your goal was to rooter it

 

[Corrreia]

OOF, how do I do it then?

 

[AltairFR]

Try for exemple crDroid 7 ,It has a dynamic rooting function
