You're right :)

For which issues do you need logs ?

I do have 4 of them on my list: gps, cam, bluetooth and fm radio.

Hopefully I'm able to provide you with necessary input ..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] _mone:
gps is a bit tricky but I can gather the logs myself.

camera I won't bother looking into it until we have no more issues, so no need for logs.

bluetooth.. would be nice if you can start taking a logcat with the bluetooth off, then you turn it on, connect the headset, and play some music or video. That should help.

fm-radio I already have half idea of what is going wrong but if you share a logcat about it won't hurt.

Gapps not installed / are not visible in app list

hi,

i installed your latest lineage-14.1-20200908-UNOFFICIAL-gtexswifi.zip together with the pico gapps.

according to trwp-3.4.0-3 everything worked fine...

it also boots and starts without problems...

but: the gapps (espacially no play store) are not there ... only the 15 "standard" applications ....

even when i started from scratch again: full wipe, install 20200908, nano gapps this time => same result...

i also tried to download / install the play store .apk but it does not work (froze on the first page)...

do you have any hint what i could try ?

thanks a lot, christoph
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] _mone:
I don't know why this is happening.. but a simple workaround is to mount system first, then install gapps.

In TWRP: Mount -> System -> Go back to the first page and install gapps as normal.

Hey there, Thanks for this awesome ROM. I can't seems to boot up this latest ROM. Just stuck on Samsung Logo. I am using the Latest TWRP 3.4.0.3, I tried dirty flashing the ROM, and also Clean Flash by Wiping Dalvik/ART Cache, System, Data, Internal Storage, Cache. And then Formatted Data as well. No joy at all. Anyone got any idea how to go about booting in , I would be really appreciated. Right now, I'm just going to use your previous build i.e Lineage 14.1 20200903

Thanks in Advance

Regards

Lee
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 2faraway2:
I suppose that a dirty flash (w/o wiping anything) of the new build should do the trick .. I had success, though with TWRP 3.4.0-1.

So I'd recommend to downgrade your TWRP, then to try a dirty flash ..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] mc0133:
The latest September 8th rom works fine on my device, can boot to it just fine. Stock camera app cannot connect to camera but confirmed that Open Camera from the google play store works fine.

I clean flashed the May 2020 version first and then before installing anything, rebooted back to TWRP, dirty flashed the September 3 build and then before installing anything, rebooted back to TWRP and immediately dirty flashed the latest September 8th build. Then I went back to TWRP, mounted system and installed the pico GAPPS (also mount MicroSD card in addition to system if GAPPS is saved to MicroSD card instead of internal storage space)

Then I finally just rebooted back to TWRP one last time and flashed Magisk and root works fine too.

(NOTE: I did a TWRP backup after every reboot back to TWRP, just in case. My SM-T280 originally had the old android 5.1.1 T280XAR0ARK3, so YMMV with other T280 variants. And finally, TWRP 3.4.0-3 was used)

Good luck!

BUT:

GAPPS are not working correctly, the system is absolutly instable... adopable storage and gps NOT working... camera not working too (but this is not a problem; can use 3party app)......

so: the system is in "alpha-realase" and not useable. the MAINS are no working: GAPPS ang GPS....

hope it will fix soon.....

My point of view: The system isn't instable, at least with MicroG instead the fu........ GAPPs !

Ok, there are several issues atm (GPS, BT Audio, Cam), but keeping this in mind the the rom can be used and is VERY stable .. ;)

Wifi disconnects itself and it costs you to reconnect.

Hey.

First of all thank you for creating this custom rom.

I recently got this tablet for pretty cheap and was hoping to get a bit more performance.

I have to confess I am a total noob when it comes to phones and tabets. But i followed the instructions and got it to run.

My only problems are the google apps. I downloaded the gapps like described and installed them with twrp, which prompted the installation as successful.

I don't have the play store though.

I downloaded the play-store as .apk, manged to install it, but when I start it it akes me to sign in. When i click on "sign in" nothing happens.

I tried it with multiple .apk versions from different sources. The same keeps happening.

What am I doing wrong? Is there any way to get the play store working?

Thanks. :)

Really newbie question

After the Rom installation, the storage used by the system is now 6.3gb. Was it really that small to begin with? Because our Tab A only has 8gb(7.28gb to be exact) of memory and there is not enough wiggle room to add other apps.

Installed this rom to the tablet to be used by my niece and nephew for their online classes.

Still thank you for the devs! Updating this device gave it a new life and purpose.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Verhuel15:
Its the same process you download the latest you reboot to recovery and select the file and install the build because you are installing above the previous build this called dirty flash your previous data will not be deleted but some bugs may be occured .Now clean flash its been recommend most of the time but your data will be deleted so you should make a backup before you proceed with Migrate(free) or titanium backup(paid and free not user friendly) or Buggy backup pro(Its user friendly and its paid) for clean installastion you should go to twrp and select wipe format all data write "yes" for confirmation and after reboot to recovery mount your tablet to your pc copy the rom and install it.There are various videos and installastions for dirty and clean flash watch some videos and you will understand the proccess its all the same.its no necesary to be about this tablet or phone(the videos).

Reboot but nothing remains all with the samsung logo,

Also tested with SuperSU-v2.82-201705271822.zip then T280XXU0AQA4-SuperSU-v2.82-boot.img, then lineage-14.1-20200512-UNOFFICIAL-gtexswifi.zip, finally after doing mount system ---> open_gapps- arm-7.1-pico-20201017.zip.

Nothing, how can I solve? do i have to put the original rom back?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 2faraway2:
What are you doing there with all these magisk/superSU-.img's ???

Why not installing it like described in the OP ? That's what I would recommend ;)

First install TWRP via Odin, then - in TWRP- install the rom and the Gapps. Boot into system and do the initial setup.

Finally you can flash magisk after rebooting into the recovery.

Also I would recommend the lastest rom version, not the may release ;)

Hello all! I've got the ROM working. Only problem is that once I add a google account and restart, I start to get the "Custom Binary blocked by FRP lock" message. Any way to disable FRP before the first reboot? Or force FRP to allow the custom ROM? I am flashing the latest TWRP and ROM from the OP.

Thank you!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] juanysara:
Any news?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sch00n3r:
For anyone trying to figure out how to get this or other ROMs working on the T280 with a valid google account (without FRP ruining all of your fun), here is what you need to know:

* Follow instructions to install custom bootloader, ROM and GApps Pico (see OP)

* Download ADB here: https://dl.google.com/android/repository/platform-tools-latest-windows.zip

* Unzip to a folder, open a cmd prompt and navigate to that folder

* On the tablet, perform initial setup and go into settings, Developer Options and enable root access (ADB only)

* Connect your tablet to your PC.

* Run the following commands:

* adb devices (confirm that adb "sees" your device as connected)

* adb root

* adb remount

* adb pull /system/build.prop

* Now you will have a copy of build.prop in your adb folder. Edit the file with notepad, or some other simple text editor that will not insert hidden characters.

* Find the following entry: ro.frp.pst=

* Comment it out (disable it) by adding a # at the beginning of the line. Ex: # ro.frp.pst=

* save the file

* Go back to adb and run the following commands

* adb remount -o rw /system

* adb push build.prop /system/build.prop

* adb shell chmod 644 /system/build.prop

* adb remount -o ro /system

* adb reboot

* Add your google account. You could add your account before modifying build.prop, but if you forget and reboot you'll be out of luck and will have to start from scratch flashing the factory ROM, etc.

* That should do it! You should now be able to reboot as much as you like.

* If you want extra assurance in the event that build.prop ever gets overwritten, you can blank out the FRP partition with FRP destroyer (I recommend): https://xdaforums.com/t/frp-destroyer-flashable-zip.3920067/

When I tried FRP destroyer without modifying build.prop, I never got to install it with TWRP as FRP would already be blocking me from booting. It is possible that I was doing things in the wrong order, but I thought I would share just in case someone finds themselves stuck like I was. I am not a pro at this, I have used CM on a few devices in the past but have never dealt with FRP before. I prefer to share my learnings to hopefully help others in the future.

Cheers!

I just got TWRP and LineageOS on this tablet last night. At first I ran into "FRP LOCK: ON" in download mode, but I just rebooted back into the OS, removed my screen lock PIN and Google account, then went back into download mode. FRP was gone. So if you have access to the OS and aren't stuck at the initial setup, you shouldn't need to go through all of those steps (though those steps are very handy and I wish I had had them available - missed them by hours!)

I don't see any mention of a custom bootloader in the OP. Did you mean custom recovery?
