[ROM][UNOFFICIAL][11][TB-X704F/L] LineageOS 18.1 for Lenovo Tab4 10 Plus

[lukaspieper]

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

Your warranty is now void.

I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this ROM
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.

Thank you @LumenReaper for this build!
I can confirm fingerprint is not working, but this is no bigger issue to me.
Flashed Magisk and changed fingerprint two times. But safetynet is still failing - no idea. My sim card is also not detected.
I use the tablet for youtube and yatse mostly. Youtube Vanced workes fine and my Bose headphones are also connected and working.

 

[PureMAD4]

Looking forward to this ROM thank you.

Thanks for installing. Glad to hear you're getting along with the current feature set. I should have mentioned that my tablet has WiFi only. Feel free to send me a log if you want, but I expect it will be difficult to fix it without the device itself.
Personally, I have not had any problems with failing safetynet. In which situation does it cause you problems?

Will continue with the fingerprint scanner as soon as I have time again.

Looking forward to this ROM thank you.

You' re welcome.

First I want to thank @LumenReaper for the efforts to keeping our tablets up to date.
Is this ROM stable enough to use it daily or can I better wait?

 

[Coffeinflash]

Personally, I have not had any problems with failing safetynet. In which situation does it cause you problems?

I do not see any issues with failing safetynet so far. It was working in 17.1 so I just wondered about the error after changing the fingerprint of the device by the help of magisk.
I will try to build the rom on my own with your sources - hopefully I can help with the non working SIM card.

 

[Coffeinflash]

If you need a SIM card , fingerprint or camera then you need to wait. For normal multimedia usage I call it stable enough.

 

[Googole]

That won't matter for me, I'll flash the ROM and patiently wait until those work on the new ROM.

Sounds great. Let me know if you run into any issues with building.

Do you think this wll also work for the TB-X705F, the successor model?

 

[Googole]

I've installed this ROM but one thing I noticed is that the internal storage and the contents in it aren't visible at all on MiXplorer Silver (The file manager I use)
It isn't visible at the default file manager too so I rolled back to Lineage OS 17.1
I would appreciate if this is fixed @LumenReaper

I cannot confirm this problem. The default files app shows me the internal storage and an SD card with content. If I would have had such a serious problem, I would not have published the rom yet.

Have you done a clean flash? Have you tried the format data option in TWRP?

Do you think this wll also work for the TB-X705F, the successor model?

I don't know, do you use the TWRP of this series?

 

[Googole]

No, I dirty flashed it.
I use TWRP for TB-X704F.
I'll also try a clean flash.

 

[flouli]

I don't know, do you use the TWRP of this series?

There is a separate TWRP for the tb-x705f series - any chance that this will work with your ROM?

I have not found a link to the code in that thread, but I expect the rom not to work when you need a different TWRP.

Great work Lumenreaper! (now I need to find the courage to install it on the only operational tablet that I own )
I did manage to build it myself using Docker & the docker lineeage-ci-cd image (see https://github.com/lineageos4microg/docker-lineage-cicd )

 

[Nuclear Blast]

Hello,

LumenReaper!​

Thanx for your work, sir!

Tell me, please - Lineage OS 18.1 made on Android 11.0?
There is no word about it in first topic of this thread.

If Yes, where can i find Google Apps package for it?
Asking , because at https://opengapps.org/ there is nothing for Android 11


Thank you
