I use three different possibilities for updates:
1. very dirty flash (new version on top of old)
2. normal dirty (just wiping "system" prior to flashing)
3. clean (wiping everything + "data format")
Just try one after another.
Obviously always make a backup with TWRP to SD.
On a clean flash it mostly workes restoring "data" afterwards.
I wouldn't recommend flashing dirty when switching or upgrading ROMs.

I guess I need help...
I tried to flash
lineage-16.0-20190219-UNOFFICIAL-viennalte
lineage-17.1-20200212-UNOFFICIAL-viennalte
on a recently bought P905.
I managed to install twrp-2.8.7.0-viennaltexx.img.tar with odin and afterwards also twrp-3.0.2-0-viennaltexx.img
When I try to flash one of the above images I get an error
E3004: This is.. viennalt your device is .
Just nothing in front of the .
Any suggestions?
In some descriptions I found:
Toggle the OEM Unlock option on
I did not find this option on my P905, Android version was 5.0.2.

Any suggestion?

Is LOS14.1 working on it?
What's it saying on the back what it is?
Hope not P905V.
No unlock option on this device anyway.
3.0.2-0 perhaps to old AND acc to 1st post you should use TWRP for P900.

    @chilobo just noticed you're in the wrong thread.
    P900 here so don't use this TWRP in post one mentioned.
    Go there

    I moved my answer to the appropate P905-section.

    I'm not responsible for any damage to your device of any sort.
    By flashing this you take responsibility of anything that happens.
    Process at your own risk!

    If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.
    I'm using pico/nano gapps.

    Instructions
    1. Install custom recovery
    2. Download the zip(s) - firmware and Google Apps additional package (optional)
    3. Full wipe all
    4. Flash firmware and gapps

    Work
    almost all

    Known Issues
    - camera
    - screenshots
    - missed icons in trebuchet tauncher (install nova or microsoft launcher and other)

    the current version is rather a technical build for testing (public, the most stable, there were already about 40-50 internal builds for fixing bugs and checking various things).
    In any way - lineage 17.1 coming soon (later today), release build done, on tests right now. And I like it much more, then technical 16.0 build.

    Thx @Valera1978 that's great news.
    Gonna test today.

    Edit 6h later first impressions:
    Coming from Lineage 14.1 Vanilla with TWRP 3.4.0-0.
    Backed up everything, full wipe plus data format.
    Installing purely the ROM with TWRP 3.4.0 led to "Error 7" 3.3.1 did the trick.
    Made a reboot to check if it starts.
    Noticed screen failures in form of small black bars/stripes which vanished after a few seconds when I let the screen settle.
    (Appearing very often even now after full installation of everything I need.)
    Rebooted to TWRP and installed BiTGapps (prefer them to opengapps as they are even smaller than pico) and Magisk.
    After each flash wiped cache/dalvik of course.

    Installed Nova prime (dark mode) and all my other apps.
    Camera doesn't work with Lineage App (as said) but does with opencamera from f-droid.
    Screenshots neither but using Quickboot is a workaround when activated in its settings.
    When writing text and correcting failures the magnifier shows only a white field with now text in it even when dark mode is off.

    Great work @Valera1978 will carry on testing.

    Edit 18h later:
    Firefox seems to have problems with it, doesn't often even open its add-on page or urls.
    Lightning browser has no probs.
    Only one sudden reboot until now.

    Edit 24h later:
    Tried to upload a pic with the screen problems but didn't work.
    Mostly occuring when switching from portrait to landscape (reproducible).
    Because of the Firefox problems I've tried the 79 version but starting it resulted directly in a reboot (reproducible).

    Thanks for the reply @bmwdroid, i was talking about the app which is version 1.2 (doh)... i have just booted into TWRP and i have version 3.3.1. So if you are using the same tablet as me, what would you upgrade to or would you leave it as is. Also, do you think i need to update the security patch level? Cheers and apologies if these are silly questions.
    Mine is a P900 v1awifi.

    I suppose that the app 1.2 refers to the TWRP app which I don't use and I've always read warnings to install it so I never did.
    It is said that it sometimes causes problems when flashing.
    And imo it's not needed anyhow.

    If you need camera working for skype or else I recommend to flash the latest LOS14,1 mentioned above.
    https://download.exynos5420.com/LineageOS-14.1-Deathly/v1awifi/
    with the deathly adiutor built in
    or
    https://download.exynos5420.com/LineageOS-14.1-Vanilla/v1awifi/
    which is a plain android system

    The development of this LOS16 seems suspended as the dev is already working on LOS17.1 which I've tested, but as said has no working camera.
    Therefore I can't say much about its stabilty but it worked with Bitgapps and Magisk for 4-5 hours until I switched back to LOS14.1.
    If you want to test it: I had to upgrade TWRP to 3.4.0 to avoid "Error 7".
    To go back to 14.1 I had to downgrade to 3.3.1 first.

    Questions show that someone is willing to learn which should be appreciated.

    i will try this process for the first time. Is there a video tutorial? thank you.
    This ROM will probably not be in development any further as the brilliant dev @Valera1978 is already working on a 17.1.
    About a video I don't know. Searching in YouTube might help finding out 😉
    Here is a very good description which I followed from @thompatry who's ROM is very stable, has a working camera (skype) and gets regularly updated.
    Download it to SD.
    As he quoted install a TWRP first to exchange the stock recovery.

    Easiest to do is use a windows PC with Odin version 3.13.
    Battery fully loaded before starting.

    1.Download TWRP 3.3.1 for v1awifi from twrp.me but choose the tar version and save it in Odin folder.
    2.Get P900 into download mode (turn it off, then press buttons Pwr, home, vol- altogether).
    Will give you a warning but continue with vol+.
    3.Start Odin then connect P900 to PC and check in Odin if a field on the left turns blue (com+).
    4.Uncheck "auto reboot" in Odin.
    5.Flash TWRP 3.3.1 with Odin onto P900 putting the downloaded TWRP file in "AP" field in Odin.
    When Odin says "Pass" all is fine.
    6.Turn P900 off with pwr button but press afterwards directly home and Vol+ together as it automatically reboots.
    Then you access the new recovery.

    If you fail the Samsung recovery gets reborn and you have to repeat steps 2-6 again but that does no harm.

    Save all what is possible with TWRP to external SD using Backup.
    Then wipe everything in TWRP (except SD 😉), select "format data" after that.
    Select install and choose the ROM from SD.
    Test if system starts. Might take a while.
    If you want to use Google apps, download Gapps from opengapps (choose ARM, 7.1 and pico) and save it in advance to SD.
    If system starts, turn it off, restart to recovery (pwr, home, vol+) and install Gapps.
