I Have a question, nothing linked to GPS. What can be linked/transfered to the internal sd card? Is there any limitation, ie. Can I linked all system file?
Can someone compile or teach me how to compile an overclockable kernel?
The device is still laggy with a 1.3GHz max clock
It would be way better to be clocked 1.5+GHz and have a schedutil governor if possible

I want to update Android on my wife's Tab A 7" so than an SD card can be formatted as internal memory. We'd replace the tablet, except that no current 7" tablet can match its screen resolution. I'm a newbie as far as rooting Android and updating the OS on a tablet, but I'm reading up on it. I have some of questions first.
Does Lineage 14.1 provide the most up to date version of Android that is available for her Tab A? If newer versions are available, how polished and/or reliable are they?
In _mone's Sept 3, 2020 post, it lists "External SDCard can't be formatted as internal storage" as a known bug. Has this been corrected yet? If not, is someone specifically working to resolve this problem?
Thanks!

Unfortuntely, you cannot format your external card as internal card yet. A lot of people are waiting for this option and I hope we will get this feature soon.
Hello, _mone and all. You don't know how excited I am to find this thread, and this ROM. When I first bought the TAB (October 2019), all the developers and users were bemoaning that there were no custom ROMs for this equipment, despite attempts by several to develop one. Now I see this one has been through the trials (and unfortunate errors--but hey! that happens!) and everyone seems satisfied. Couple'a quick questions--
is lineage-14.1-20200929-UNOFFICIAL- the most recent build?
Can anyone direct me to a listing of the Lineage features? I have specific things that I desire (not necessarily need, obviously, since I've been using the stock ROM these couple'a years) such as page animation, the ability to use an alternative on-screen method of turning off the screen--things that you often or sometimes find in custom ROMs.
And, probably a very general question--are people overall satisfied with using this ROM?
I've downloaded the pertenent files, the new Twerp, the ROM (duhhh), and I'll snag the most recent version of GAAPS once I hear back on these questions, but I'm going to hold off on flashing anything. Though a part of my mind is going to be like that child in the back seat--"Are we there yet? Huh? Are we there?"
And, anytime a person benefits from the work of a developer who has devoted his time, effort, and skull-sweat to something he provides gratis, I have to say in advance (and I'll say afterwards too, 'cause you can't say it enough) Thank you thank you thank you! I look forward to making my TAB, which was partly under the perview of Android before, my own at last.

Wondering if @_mone is still actively developing this rom? lineage-14.1-20200929-UNOFFICIAL appears to be the most recent build he has released, yet it seems to work ok. Have to thank him for even bringing a newer android to the tab
Wondering if the battery image when charging the battery powered off can be fixed? Currently, it displays upside down and looks funny.
Also scrolling through the homescreen pages seems to not be particularly smooth (default homescreen launcher that comes with the rom, haven't tried any third party homescreen replacement launcher app you have to get thru the google playstore)

Are you really sure you got an GPS fix with that method ?
Imho you only get a network location ((Wifi), but not a location produced via satellite (GPS)..
I've seen several people on this thread say the audio for this ROM doesn't work.
Is this still a problem or has it been fixed?
My use case is mainly using the tablet's built-in speakers or wired headphones.

Hi _mone, great job and it works very well -> THANK YOU
!Is there still hope that the system camera app will no longer crash?
I am using "Motion Detector" and I see an image in the app settings for the front and rear camera. But the app doesn't want to trigger on movement (I've already tested "Open Camera" and "Footej Camera").
Greetz,
Frank
Is this new version solving the issue of wifi disconnection?
Not sure. Camera is always a mess to port properly.. I'll give it a shot when I can.. no promises.
I don't have any wifi disconnections, you probably want to clean install the latest build. If the problem persist grab and share a logcat and I'll see if I can help.

LineageOS is a free, community built, aftermarket firmware distribution of Android 7, 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. You can also view the Changelog for a full list of changes & features.
Instructions :
- Download the latest build and (optional) GApps
- Boot to recovery
- Flash the latest build
- If you want GApps you have to mount system first:
Mount -> System -> Go back to the first page and install GApps as normal - Reboot
- ROM : LineageOS-14.1 for gtexswifi
- GApps : https://opengapps.org/ (ARM - 7.1 - pico)
- DO NOT Report bugs if you're running a custom kernel or you installed Xposed
- Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
- If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
Code:What is your-- LineageOS version: LineageOS Download url: Gapps version: Did you-- wipe: restore with titanium backup: reboot after having the issue: Are you using-- a task killer: a non-stock kernel: other modifications: Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:
Known Bugs :
- Camera doesn't work (use opencamera instead)
- RadioFM doesn't work

You can now format the external sdcard as internal storage4For 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://forum.xda-developers.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!
