Is there any way to get the ROM in which you can install the google services, you know play store and that?
this absolutely makes no sense at all (and isn't possible without a LOT of trouble - if it would ever work). the purpose of this ROM is avoiding Google. You can use the internal Aurora Store which has all apps as in google play (as it directly links there).
what do you miss in /e/ ?

Sorry, please ignore

Hello steadfasterX, I see you're still active about the SMT-285, I really like your ROMs but I'm a person that needs google in their life. I know that the /e/ OS is impossible to install/flash Gapps, I'm humbly requesting you if you could look into jedld's Omnirom 6.0 here https://bit.ly/3dm9oK7, I think this is the most stable rom of jedld for SMT-285. I hope you could consider fixing the rom's bugs which are:

1.) Apps froze a lot when installed in external sd card (formatted sd card as internal storage).
2.) Speaker phone does not work in calls.
3.) Bluetooth ear phones and wired earphones does not work during calls.
4.) Data connection sometimes won't work but switching to on/off in airplane mode does fix the problem.
5.) Direct Wifi does not work.

Thank you :)

well what I can do is building LOS again. I cannot say when though and for sure I won't do much dev on that as my main focus with this device is navigation (i.e. diOS which is based on /e/ OS)

Thank you for your quick response, I really like this ROM because it's almost bugless but it doesn't have an option to put Gapps on it, I would really appreciate if you build LOS again.

I have a question, is it okay to flash your kernel (https://bit.ly/39ExNt5) while i'm using omni rom of jedld (android 6.0)? and should I just download this as zip and flash it using TWRP? thanks!
Uhm it does not work like that. You need to BUILD the kernel. So you need a proper dev environment to use build.sh or using mka. The means downloading android omni sources and building the full boot.img just with these kernel sources would be the regular way doing so.

If you never did that before the easier way might be to extract the zImage file (which is the kernel image) from this ROM's boot.img , doing the same for your omni ROM and exchanging the zImage within.. The AIK tool (search xda) can help on that but prepare that this might not work on the first try

Its seems very good work. Thank you for offering /e/ OS as an option, to devices like SM-T285.

Consider setting up a torrent for big files (like tar, img etc) because the download speed is very poor.

Dl speed goes up to 100mbit. Either it is on your site or it was bad luck atm when you tried downloading.
Hello, may I ask do you know how to fix a bug when this tablet is powered off while charging it boots up to TWRP instead of showing an animation where the battery is being charged? thanks! Its jedld custom rom (CM13 android 6.0)

the fix is using this ROM instead ;)
if you dont like my ROM ask jedld to fix his ROM. This is nothing you can fix without building it.

    Code:
    /*
    * I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...).
    * Please do some research if you have any concerns about features included in the products you find here 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.
    * Your warranty will be void if you tamper with any part of your device / software.
    * Same statement for XDA.
    */


    About /e/
    /e/ is an a mobile ecosystem (ROM + onlines services) that:

    • is open source
    • is pro-privacy
    • is compatible with most existing Android applications
    • cares about usability
    • is as far as possible freed from shackles by Google and OEMs
    • already exists!
    It’s the alternative to the Apple/Google duopoly on the smartphone.

    ... so again and just to be clear: /e/ is not just a ROM, it is more a complete privacy ecosystem and consists of:
    • an installable mobile operating system for smartphones, which is forked from Android and strongly “ungoogled”
    • a set of sorted and improved default open source applications
    • various online services that are linked to the mobile operating system, such as: a meta search engine for the web, drive (with synchronization), mail, calendar, notes, tasks.


    Features

    • Based on the stable Lineage OS
    • microG fully pre-installed with Signature Spoofing in restricted mode!
    • All features described on the /e/ page: What is e
    • All features and fixes of LineageOS
    • My builds come with full OTA update support :)
      ... you know that thing which informs you that a new update is there and where you just click to download + install ;)


    Difference from pure /e/ or: why are the builds UNOFFICIAL?

    • There are no differences. its pure /e/. "just" build on my server ;)


    Known issues:

    Keep in mind that this is brand new stuff so it may (still) contain unknown issues!
    So back up regularly and frequently!

    • Camera does work but only for photo, i.e. video recording fails.
    • If you find a bug not listed let me know and SHARE LOGS! -> READ FAQ#1 for how to provide proper logs.


    Requirements
    • Latest TWRP or SHRP (recommended) build.
    • Do a full (i.e. Nandroid) backup before doing anything!
    • Samsung STOCK firmware should be on T285XXU0AQH1.
      You can check your current firmware version in Android -> settings -> About / Phone info -> Baseband version
      If you like try first without flashing this firmware but if you encounter any issues upgrade to this version first before reporting
      Fast and (afaik) good site for downloading: https://sfirmware.com/samsung-sm-t285/
      (scroll down and type T285XXU0AQH1 in the search box, choose the one for your country, download, flash as usual, flash TWRP/SHRP again, flash this ROM)


    Installation
    1. Full clean install as described here (FAQ #2) is highly recommended. DO NOT REPORT ISSUES when you have skipped that step!
    2. Flash /e/
    3. Optional (if you want root): Flash Magisk
    4. Flashing OpenGapps ????? STOOOOOOP! NO No no! you don't want that on a google-free phone! /e/ contains everything you need to live without Google! So flashing OpenGapps on /e/ is like using a bit more secure LOS but that's not the point of /e/. Either try without or go with LOS (imho).
    5. Boot it (will take a bit on first boot!!! be patient!)
    6. Enjoy the most easiest way to have a privacy focused and google-free phone!

    FAQ

    Frequently Asked Questions (FAQ)

    Q #01: I want to report an issue. What is the proper way to do so?
    I'm glad that you are asking: before doing so check the KNOWN ISSUES topic in the OP and ofc the other FAQ's listed here!
    if you have an audio issue follow FAQ #6 instead.

    If your issue is not listed there click here to proceed:

    If your issue is not listed there follow the directions here briefly and I may can fix it:

    logcat GUIDE

    Ensure you have done a full CLEAN install before doing so (refer to FAQ #2 for what that means).

    Warning: NO SUPPORT when:
    - magisk is installed (known to cause issues sometimes - regardless of the ROM or version)
    - Xposed is installed (known to cause issues sometimes - regardless of the ROM or version)
    If you have installed any of these UNINSTALL or better do a FULL CLEAN install (see FAQ #2) before doing anything else. Often enough these above causes several issues like battery draining, problems on booting and much more. Even when they may work properly you should re-produce your issue without them first and follow the above to grab the log.

    Magisk is a great piece of software and besides that it is Open Source which SuperSu never was.
    I just saying I do not "support" issues when you have Magisk installed. Why? It is (like Xposed) extendable with modules (made by whoever) and those can cause billions of issues.
    Other then that magisk was sometimes the reason for battery drain etc. Magisk modifies the boot "process" and sits very deep in the system (which is needed to make it work ofc) but that has the potential to make a system/ROM unstable or result in strange behaviors.

    so in order to support a specific issue I have to be sure the ROM is in a "clean" state, no magisk, no xposed.
    Pro-Tip: a very first test is to set magisk on core functions only to see if an extension causes your issue or not.


    Q #02: I want to install clean, how? What is a clean install? What is the recommended way to flash a new ROM version?
    A clean install ensures that there are no leftovers from any previous install. One can say that there are 2 phases of a clean flash:
    1) regular
    2) full - when you (still) encounter issues

    Usually the regular one is fully ok when flashing a new ROM version but if you encounter strange issues nobody else is reporting or if a release post is recommending it you should do a full clean install instead.

    A regular clean install can be done like this:
    • WIPE -> Advanced -> select: System + Cache
    • Flash the ROM
    • reflash root addon/magisk if you want root

    A full clean install needs 2 steps more then the regular:
    • follow the steps for regular clean
    • go back in WIPE -> touch the "FORMAT data" button and type "yes" to format the internal storage (you will LOOSE ALL YOUR DATA - obviously)
    • REBOOT -> Recovery
    • Flash the ROM
    • reflash root addon/magisk if you want root
    It is absolutely recommended to create a backup before and COPYING IT to your PC(!) before doing the above.


    Q #03: Are there any plans or a chance of official /e/ builds?
    No plans on my site. I may check that later but the chance is very low.


    Q #04: Will this ROM support / pass SafetyNet?
    When you install Magisk you can hide and so yes you might be able to pass SafetyNet. Which can change every day though because even when that might work atm you should note the following:
    Magisk has its own protections to ensure you pass safetynet but this is something which will change one day and there is no known method yet to workaround that.


    Q #5: Is there an /e/ specific FAQ?
    Sure:

    • FAQ: click
    • Forum: click
    • HOWTOs: click (a great resource for all your first questions)


    Q #6: issues with audio (e.g. echo's, silence on one or the other site, ..)? Read here how to provide a specific log for that:
    Do the following steps:

    • 1) Ensure you have adb set up on your PC, and have adb debugging and adb root enabled in developer options on your phone
    • 2) Then perform the following (all one command)

      On Linux:
      adb root ; adb shell "stop audioserver; logcat -c -b all; start audioserver" && sleep 10 && adb logcat -b all |egrep -vi "(dialer|telecom|ril|gsm|touch|brightn|dct|QC-time-services|SST|sensors|AlarmMan|Lights|perfp)"

      On windows:
      adb root ; adb shell "stop audioserver; logcat -c -b all; start audioserver && sleep 10 && logcat -b all |egrep -vi '(dialer|telecom|ril|gsm|touch|brightn|dct|QC-time-services|SST|sensors|AlarmMan|Lights|perfp)' "

    • 3) Then re-produce your audio issue and cancel the logcat from step 2 before hanging up!

    • 4) Share the logcat output from the console screen using paste.omnirom.org

    Q #7: I'm scared about that microG , I don't want to expose my phone so is this /e/ version a security risk?
    First of all you need a lot of trust installing ANY custom ROM. A developer can do nasty things right? Besides that yes microG allowing to let apps act like as they are another app, also known as signature spoofing. This CAN be a good and a bad thing. Read on why my builds are different:


    In general the microG patch is an all or nothing. A ROM which supports microG (i.e. signature spoofing) have that feature enabled, always.
    The difference in my /e/ builds is that I am using the "restricted" option of signature spoofing so as long as you trust me you are as safe as without microG.

    espeak is a known issue of /e/ OS and should be fixed hopefully anytime soon: https://gitlab.e.foundation/e/backlog/-/issues/1890
    cam is nothing I will work on sorry..
    signal issue is very likely because of your STOCK firmware --> make a screenshot of the full " about" menu in settings (where you see build number etc)
    Here are some screenshots
    This one is from "about tablet" menu.
    Screenshot_20201208-183359.png

    And I bonus some screenshots include some information i have from the "Device info HW" app (ru.andr7e.deviceinfohw, maybe you've already known it before).
    Screenshot_20201208-183425.png
    Screenshot_20201208-183433.png

    That's all the screenshot i provided.

    Sorry ... I really read it and ended up forgetting that GAPS doesn't work ....

    Everything is ok except some problems/issues.
    First is the camera. As you have said, camera does work but only for photo. But it only happens on the foundation.e.camera (default camera app). And in other apps require camera such as Qanda, it does not work. Like this:
    The second problem is the cellular (or phone signal) problem. It says that "Emergency calls only" and I can't use mobile data(4g) or make any phone calls.
    The next one is stability. Sometimes Espeak have fc (force-close) after using camera app.
    and sometimes Bliss launcher (pre-installed) have some fc when i press home button.
    Sorry if I can't provide to you the proper log because of some reasons.
    Anyways, the rom works very well and actually better than the LOS i used before.
    Without Google spyware, The performance increases and i have more ram to do other things.
    I hope you will fix those issues i have mentioned above in future OTA updates.
    Thank you for the nice work.

    ok your cell service issue could come from a too old stock firmware. yours is from 2016 and there were some releases later on.
    I have adjusted the OP with instructions (pls see topic "Requirements") with the firmware I am using without issues.
