I have successfully installed the ROM - it works fine. But I have problems with the using of root.
After installing su (addonsu-15.1-arm64-signed.zip) and activating in Developer options, the tablet crashs if the app (eg. adaway, file explorer) uses the allowed root access. What do I have to do to make it work? Or is it a bug?

Sorry, but for what exatly I need the Hall Sensor?

Some cases have small magnets in them for on/off when opening/closing them.

Why not use Magisk for root?
But either way you will need to have System R/W enabled for full root access.

No Sim Card will be found on my the X704L - someone got the same ?

No sure if I understand this correctly "will" ?
Have you tried it or are you supposing it?
Have you actually got a SIM inserted and its not being "seen" by the tablet?

I have just installed this ROM on my X704V but as I don't use a SIM obviously it reports that as "No SIM" .

BTW I'm trying hard to give this ROM a chance but I'm not really sure about it. Too many apps force closing or crashing or just not running properly. Also I miss the "hall sensor" and the TWRP not using NTFS on the SD is a big loss, due to the inherent file size restrictions with Fat32. Cannot get Gapps to link correctly with playstore installed apps either. Cannot get Atmos or Viper to work correctly. I actually think it lags more than stock, but that may be me, I haven't as yet run any definitive tests, its just that it appears to be not as "slick" as stock. To me, in its present form, the only advantages of this ROM is (1) it offers an alternative and (2) updated security patches.

Yener90 I'm sure has given many hours of his time to offer us this alternative and I FULLY appreciate all he has done and we have been told by him why he did it, which I fully agree with. Please understand, the above is just my early findings with this ROM and after all is just my opinion.

@yener90 I sincerely hope you do not take any offence to me posting my experience with your ROM.

I've got no complaints at all....well except something really tiny.....led goes red when fully charged and flashes red when you have notifications but before it was green but otherwise I'm loving it. Can't wait for Pie :)

It's your feedback, why should I angry about it? But I don't have any of the issues you are having. Also I don't use sound features. I also thought about porting stock dolby to our tablet. And the only lag, I see, is in task switcher. Otherwise It runs well for me :confused:

Could be true, never tested it. Double tap to wake worked for you on stock? I never had it in stock :eek:
The touchscreen doesnt support it. I also wanted the feature, but it's for devices with synaptics touchscreen. Ours is a special goodix panel.
But the good point is, its name is GT9110P. P stands for pen :p

I also saw that issue. Oreo is much more restricted. The charger library wants to give signal, Oreo forbids it. Therefore it doesn't work correctly currently. I need to learn, how to create SELinux rules then I can fix it.

Hi yener90,
Thanks for everything!

Do you know if the TB-704F has a GT9110P screen too? If so, would it be active styles compatible automatically?
That'd be great.

Hi guys,
Yener and also LumenReaper, You're the greatest! Nice that this rom is available now!
I'm an x704l user still on stock Lenovo rom. Is there a 'from scratch' manual to flash this lineage rom, including rooting?
Kind regards, Vicenza

Really all you need is to read the OP and follow the instructions EXACTLY.

However a read through this comparatively short thread will also yield valuable information to assist you.

When you have it 'up and running' just flash 'Magisk' to root.

yes it worked and was one of the reasons i bought the tablet back then (long time stick to LG Phones ;) )

but getting in touch with the fingerprint unlock finally it it is ok now

so only the broken SIM makes me cry in my pillow , for the rest - thank you again

    LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1 (Oreo), which is designed to increase performance and reliability over stock Android for your device.

    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.


    What works:
    Wifi
    Bluetooth
    Audio
    LED
    USB
    RIL
    Encryption
    Fingerprint
    Camera (partly)

    Broken
    Camera (autofocus & hdr)
    Hall sensor
    Selinux Enforcing

    Source code:
    device: https://github.com/yener90/android_device_lenovo_TBX704
    kernel: https://github.com/yener90/android_kernel_lenovo_msm8953
    vendor: https://github.com/yener90/android_vendor_lenovo_TBX704

    Important
    If you are using this ROM first time, wipe data. Wipe data completely. I mean the option where you need to enter "yes". Use this option and then flash the rom.
    This ROM only works with the TWRP I added.

    If you want to use GAPPS, flash it directly after flashing ROM. Don't let the ROM boot. Otherwise your device will not get certification, so you will not have Google Access.


    Instructions (thx @matshias, just changed few lines to get ROM flashing working)

    1. Put your ROM (and GApps) onto your sdcard (sdcard must be exfat or fat32, NTFS not supported)
    2. Install fastboot and adb on your PC, e.g. from here
    3. Enable developer options and in there select to unlock your bootloader by enabling OEM unlock and enable USB debugging
    4. Connect your PC to your tablet and run
      Code:
      adb reboot bootloader
      using adb on command line. The tablet will reboot into bootloader mode where you will only see the Lenovo logo. Now you use
      Code:
      fastboot oem unlock-go
      to unlock. This will factory reset your device
    5. Don't setup, cause you will need to format your tablet later again. Shutdown tablet. Hold volume up and power button to start to bootloader
    6. Then run
      Code:
      fastboot flash recovery twrp-3.2.3-0-<your-filename>.img
      to flash TWRP
    7. Select with volume buttons "Recovery Mode" and press power button
    8. Select to write to system, otherwise you can't flash ROM
    9. Backup at least system and boot partitions to your sdcard cause you will wipe data in next step. Choose "System Image" for the system partition backup.
    10. Format data using this tutorial
    11. Flash ROM
    12. Optionally flash SuperSU or Magisk in TWRP which should install system less. Keep OEM unlock enabled if you flash or modify anything
    13. Restart

    Please don't support Lenovo and buy their tablets
    Code:
    [I]Updates vary depending on the model where our tablets receive Android and security updates after the introduction. 
    We announced Tab 4 10 Plus in February 2017 and since then it has received seven OTA updates. 
    However, this model has reached the end of its update cycle and will not receive any more updates in the future.
    - Lenovo (2018-05-11)[/I]
    Just seven updates and not even one major upgrade, please don't support them.

    Reporting bugs
    Please tell what mods you are using and what tablet variant (TB-X704F or L or ABCDEFGH..)
    If your tablet doesnt start:
    go to TWRP. use file manager, go to sys/fs/pstore, copy the files and upload it here.
    if your tablet starts and bug appears later:
    go to TWRP. use file manager, go to sys/fs/pstore, copy the files
    start your tablet normal, let the bug appear, enter adb root
    use adb logcat and adb shell dmesg, copy the content to a text file and upload here

    The system itself runs very well. Also TWRP is very nice in landscape.

    Maybe some notes after a short test phase, because your post is not so detailed yet.

    Works:
    - Encryption (forceencrypt is enabled)
    - Clearly better audio quality than in Lineage 14.1 (Yener has already made me aware of my mistake)
    - Significantly newer kernel (3.18.115 instead of 3.18.31)

    Broken:
    - Hall sensor
    - selinux (for completeness only)

    All in all very good rom. Thank you Yener!
