I'm trying to install an up-to-date ROM (the one above), which required this one to be installed first. I flashed this rom (https://download.exynos5420.com/Lin.../lineage-14.1-20220107-UNOFFICIAL-v2awifi.zip), but I'm stuck at the animated LineageOS boot logo. What can I do to fix this?
I also did a full wipe (including internal storage/SYSTEM partition) before starting because I had to expand some partitions. Would that cause this problem?

edit: reflashed AP/BL/CSC from T900XARBPL1, booted stock rom, dirty flashed this (LOS 14.1) and ran it, and then the /e/ unofficial rom ran.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.* (Nougat), which is designed to increase performance and reliability over stock Android for your device.

    Code: 
    #include <std_disclaimer.h>

/*
 * Your warranty is now void.
 *
 * We are 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 us for messing up your device, we will laugh at you.
 *
 */
    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. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.


    Important information:
    This thread is for Unofficial LineageOS 14.1 (v2awifi) ROM for the Samsung Galaxy Tab Pro 12.2. The following will not be supported here:
    • Custom kernels
    • Mods
    • Xposed

    Do not ask for ETAs. If you do, I will ignore you and your post.

    SEANDROID ERROR
    • If you see a message at boot about Recovery or Kernel is not SEANDROID Enforcing, you can ignore it. This is just telling you that you are not running Samsung stock software. It has no effect on recovery or the ROM itself nor related to either.

    I don't support Xposed and any logcat which includes a Xposed module will be ignored.

    You're kindly invited to not report bugs if you:
    • Flashed a custom kernel
    • Installed or did mods from untrusted sources
    • Modified system files

    Bootloader Information
    You need to make sure you have a Lollipop bootloader installed or else your device won't boot. Here you can go grab the latest bootloader and odin and flash it in download mode. Read all the steps before you do this.

    Make sure you have a full backup because just in case you something fails.

    Here are the steps to flash this via ODIN:
    1. Make sure you have a full backup because just in case you something fails. Here are the steps to flash this via ODIN.
    2. Reboot your tablet into download mode. Do this by first switching off the phone, then pressing and holding the volume down + home button together and then pressing the power button. Press volume up button to enter download mode.
    3. Open ODIN on your computer. You?ll see the ID:COM box turning yellow with a COM port number upon successful connection with the tablet.
    4. In ODIN click the BL button, select the bootloader firmware. It's a tar file.
    5. Make sure Auto Reboot & F. Reset Time options are selected in ODIN
    6. Click on the start button. When the process is completed your phone will reboot.

    Installation
    1. Download the zip(s)
    2. Install a compatible Recovery (This will not work with the P900 recovery)
    3. --I have built a new version of TWRP with the MM kernel. MTP, Vibations, ADB now work and there are performance increases. Link
    4. Perform a nandroid backup of your current ROM (optional)
    5. Wipe data/factory reset
    6. Flash LineageOS
    7. Install the Google Apps addon package (Optional)
    8. Reboot

    Root
    The SU root binary is no longer installed with ROM by default. If you would like to install root, please go here and download the binary.

    Just a quick update.

    I am very close to releasing Oreo. I have a few more bugs to work out and then I feel comfortable to release it.

    Hey Guys,

    I know it has been awhile since I have personally posted an updated. Life has been super busy for me. Working 60 hours a week, wrapping up this job, starting a new job and moving. Don't get me wrong, I ready everyone of your posts and work with @DGT79 on posting solutions, looking at logs, and making this ROM better.

    With the Exynos5420 Team having a build server "Jenkins", I will no longer being announcing builds. We are working on setting a final scheduling on builds but it is looking like weekly builds on Fridays. This week, we will run builds tomorrow due to Jenkins going down for some maintenance. You can find device changes on the Exynos5420's GitHub account. We are working on a change log server but that is a few months out. If you have any questions, about this please let me know.

    So a new hot topic item is root. A lot of ROM teams are moving away from baking in root (no longer having the SU binary installed) into the ROM. There is multiple reasons behind this. Some apps just will not flat out work if it detects any form of the SU binary installed. For an example Pokemon Go or TV streaming apps. Also there is concern of identity theft with the SU binary being enabled. We, as a team (Exynos5420 Team), have decided to follow this path. It should be up to the user for this risk. It is easy for you to install the SU binary if you want it though. You just need to flash a root zip after flashing the ROM. From here, you can use whatever SU program you may want such as SuperSU. You can find the SU binaries here from Lineage. I will update OP to reflect this. You can find more information about why root was removed from the ROM here.

    Another thing that you may have noticed on the downloads site is there is a new ROM the Exynos5420 team is developing. It is called LiquidDeathOS. It is a ROM based off of the Exynos SOC. We have plans to expand it to all Exynos SOCs in the future. We have a few builds out for Alpha testing and it is looking promising. It is very early in development and has a lot of bugs so please be patient. What we are trying to accomplish is to focus on speed, stability, and battery life. With this new ROM, we will be using AOSP code directly from Google. There will be no CAF code involved. (If you do not know what CAF is, please Google Code Aurora.) As soon as I feel comfortable releasing a build for public consumption I will. So hang in there. It is going to be fantastic and will blow Lineage out of the water.

    I think that is all I have for right now for new updates. As always keep giving the great feedback and I will keep putting out the great work. Feel free to donate me a beer or two.
