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

[tboege]

Running 2021-06-27 I can confirm, that GPS is working. I am usure, if it worked rigth after installation, but at least after running Magisk (and MagiskHide) and fingerprint from
Lenovo/LenovoTB-X704F/X704F:7.1.1/NMF26F/TB-X704F_S000056_181015_ROW:user/release-keys
to
Redmi/sweet_global/sweet:11/RKQ1.200826.002/V12.0.6.0.RKFMIXM:user/release-keys

Maps are now working.

I first discovered, that GPS was working in the app "GPSTest" - maybe this app has to be started before Maps - at least once

I can confirm that GPS is working build 2021.06.27. when I followed what person above me did (with first installing GPSTest, then rebooting and installing google maps), however without any root or magisk. Entirely stock, only have gapps installed.

Installed the 18.1 this Thursday and what can I say. Didn't have any reboots, everything is woring and running very smooth.
I think it is even faster then 17.1

Big thanks to @LumenReaper

Then you may contact the manufacturer OK, all joking aside. I've already asked you twice for a logcat.

Until then, does anyone else get a message like that with the TB-X704L?

 

[Nuclear Blast]

Will do logcat, sir

I have too, and Bluetooth don't work aptx only AAC mode

I installed the last version and got the same error message

I've been using this ROM for a while now, and really the only thing that bugs me slightly is that the hall effect sensor works for waking the tablet, but not for sleep. At least not with the magnetic cover that I'm using. This means:

• Opening the cover wakes the tablet
• Closing the cover does not shut off the screen

I'm know this worked in the stock ROM. This is fairly minor, as I have the tablet go to sleep after just a couple minutes anyways.

Other than that, is there any reason you haven't gone the extra step and made this an official LineageOS ROM? I don't know much about the process of doing that myself, so pardon the ignorance. Just curious.
Also thank you very much for your work and for offering the ROM. I sleep better at night knowing that my sheet music tablet (and some media consumption) is up to date.

Hi LumeReaper, thanks for your work to bring 18.1 to this tablet. I flashed the newest build 2021.08.07 and have the same message during booting "Android System - There is an internal problem with your device. Contact your manufacturer for details"; also normally at the first boot it get frozen and screen goes black, pressed the power button and the Lineage logo appears and this time it let me log in, after that it works, shutting off randomly. I have no knowledge whatsoever in how to do a logcat, but tried with the app "LogcatExtreme" and this is what I got. Don't know if is of any help.

 

[Android.Sysop]

If I read everything correctly, then everything works with this ROM except:
- Cellular network (SIM cards are not recognized)
- Hall effect sensor does not switch off the screen when using a magnetic cover, but the wake-up function works

Is that right so far?

 

[LazyT]

Is that right so far?

For me wireless display isn't working, the service crashs (missing libs?).

Haven't had time to try it myself yet, but added it to the list in the first post with the status "unconfirmed".

Closing the cover does not shut off the screen

I can't confirm the problem, I also use a cover and both work for me.

also normally at the first boot it get frozen and screen goes black, pressed the power button and the Lineage logo appears and this time it let me log in, after that it works, shutting off randomly.

I can confirm that sometimes a single reboot is necessary after flashing and reaching the launcher. The rom initially had problems with random reboots, but these have not occurred for several versions now and have not been reported since.

I have no knowledge whatsoever in how to do a logcat, but tried with the app "LogcatExtreme" and this is what I got. Don't know if is of any help.

To get useful information via logcat, ADB or root must be used. An app in Android's sandbox does not have the necessary permissions.

Haven't had time to try it myself yet, but added it to the list in the first post with the status "unconfirmed". What hardware and software do you use on the "display" side?

If it were just a step, the previous developers would have already done it. First you have to go through a long list of requirements and then you commit to being the maintainer of the rom. In short, think of it as an unpaid mini job. Don't get me wrong, I love working on open source projects, but I already have limited time and next month that time will decrease even more as life is changing.

Posted adb logcat for the 17.1 here, guess it's the same on 18.1 (tablet is not my own, have to check it again if interested).

Tried on 2 different LG-TVs (e.g. OLED-65B7D) with the latest available firmware. With my phone, it was working fine.

Thanks for looking into this.

Is there no one here who can offer support so that LTE / the SIM card also works?
LumenReaper only has one TB-X704F!

Try installing the 17.1 ROM 1st then flash this over the top. I have got 4g working that way

I have 4g working fine. I installed 17.1 1st and then 18.1 over the top and it's been working great

I had the TB-X704L with LOS 17.1 from Codeworks (version 31/05/2020) with TWRP 3.3.1.0 from Codeworks.
Now I have flash new TWRP 3.52-9-0 and LOS 18.1 over the old versions, it works.

@LumenReaper
Thank you for the great work and your free time that you are making available.
