Strange.. I'm not able to transfer files to system/lib

I even got Solid Explorer.. enabled root & checked Magisk to ensure it was enabled.

I also did a clean install of this ROM initially & only dirty flashed an upgrade a few days ago.

Am I doing something wrong to not be able to transfer files into /system/lib ?

I can even show pictures of Magisk having Solid Explorer enabled in SU permissions.

firstly i hope I find you and yours well and safe in these odd times

I just bought a t510 to use with my bike trainer thinking its a 64bit processor so will run full 64bit (required for zwift)

nope

so A quick question before i look at returning this is this rom running full 64bit armv8 code supporting the armeabi-v8a ABI and can anyone running it see the zwift app in the play store (not zwift companion)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Nope, I tried that with initial builds, but trying to build custom ROMs for a device you don't have is like trying to tune an engine without the car. It just isn't practical.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] kvnjonathan70:
no it doest run. i tried using wine to see .exe support but not working. i think if u can get apps source code and with some modification for converting arm64 app to armv7a might help.

Is there way to port it. If you have working tutorial, could you link please. I don't find any rom for this tablet:(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, you just need to start with the kernel, vendor and product partitions for the SM-T515, and you should be able to use any of the system images from my custom ROMs. I've already built the recovery partition for you, and you could grab my custom kernel from that (which disables the Knox boot security features, but doesn't fix MTP). From there, however, it's all just troubleshooting...which is difficult to document.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] flipside101:
Thanks for checking , the zwift devs seems fixed on armv8 so unless samsung pull there finger out and update the to a fully 64bit platfoem with the right ABI support its pretty much dead in the water so is likey going back for a refund.

Any chance we could get slightly higher clock speeds in the kernel used in this ROM?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] kralq:
The CPU of our tablet is Exynos 7904 that has 2 Cortex-A73 and 6 Cortex-A53 cores and is 64-bit capable (arm64-v8a).

Yet the stock kernel and ROM are 32-bit (armeabi-v7a).

I'm not aware if it is possible to build the kernel and the ROM as 64-bit, but I doubt it since the stock kernel is 32-bit.

I wonder why Samsung are using 32-bit kernel on SOC that they adverse as 64-bit (from https://www.samsung.com/semiconductor/minisite/exynos/products/mobileprocessor/exynos-7-series-7904/):

I've been playing around with Raspberry Pis for a while and when I got my RPi4B I went searching for a true 64 bit OS for it. Turns out someone had come up with a 64 bit Gentoo distro for it. I was hesitant because I switched from Gentoo to Arch about ten years ago to avoid building every single package. But the Pi Gentoo has pre-built packages. Someone has to have the skills (I don't) and motivation to put in the work. Runs like a charm.

Oh, but you can still build a package with emerge for any that aren't pre-built.

Works like a charm. Only two things are not working how they should:

1. double tap to wake up

2. sdcard is not properly working

Great job and thanks!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, you might have noticed that I just released new builds of LOS 16 and Nexus Stock LP (based on LOS 16) yesterday, and it fixed both the Double Tap to Wake bug and the initial crashes when launching Phh Device Settings. Unfortunately, the recent churn in the LOS 17.1 code base has broken several of our patches, and we're waiting for some upstream fixes.

I haven't been tracking the SD card issue, but I released a Nexus AQ build (based on AOSP 10.0) that seemed to avoid the problem, indicating that it's probably a bug in LineageOS 17.1 (or our GSI patches for it). I'm hopeful that this next round will also address that.

For now, my favorite custom ROM is still the Nexus Stock LP build. Until we get some of the bugs worked out on LOS 17.1, it's going to be the most smooth and stable.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I'm convinced that Samsung's decision to go with ARM32 (with 64-bit binder) for the SM-T510 was because of the low 2GB RAM in the base configuration. While overall performance is usually better running in 64-bit, RAM-constrained devices will have some serious performance issues that can be avoided by using the 32-bit instruction set. It just has a smaller footprint in memory.

I would be interested in migrating a 64-bit vendor partition from another Exynos 7904 device, such as the Galaxy A40. It can be a tedious process, however, so I wouldn't undertake it if there was any chance that the Android 10 release coming in September might be 64-bit.

Hey,

does that also fit for the SM-515? Only difference is LTE ... (not used at the moment).

What about upgrades, when I install LineageOS "unofficial" do i receive all the standard LineageOS Updates?

Is there a speed difference between the stock Samsung SM-T515 Rom and LineageOS?

Thanks!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] FL0R1AN:
You have to unlock the bootloader.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] FL0R1AN:
This ROM is for SM-T510

Unoffcial LineageOS does not support OTA updates...hence Unofficial.

There is a lot of difference between stock Samsung and this ROM, I personally use NEXUS Stock from the same DEV. and it is light speed faster than Samsung stock ROM.

You think of this one? https://xdaforums.com/galaxy-tab-a/development/rom-nexus-stock-2019-galaxy-tab-10-1-t4056233

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
The LineageOS OTA update servers support official builds only. You have to update UNOFFICIAL builds manuallly.

I'm not aware of anyone building custom ROMs for the SM-T515, but you should be able to flash GSIs (ARM32 w/ 64-bit binder with a/b). You'll just lose the MTP and cold charge fixes. I could potentially wrap those up in a .zip update for you, but you'd need to be in charge of testing and maintaining it.

ROM flashed in Odin properly, seems to be stuck at boot

Hello. I managed to flash the ROM image through Odin with no issues, and I've been waiting for it to reboot into TWRP as the directions state it will, but it seems to be stuck on the screen which I assume is the Lineage boot animation, with the circle following the curved line. I know sometimes these take time to get booted up for the first time, but it's been over half an hour and nothing has happened. I can't seem to force shut down the device by holding power or use the other key combos to get back into download or directly into recovery either, presumably because it's already past that point in the boot process.

Am I just being impatient or did I miss something somewhere, and if so can I fix it?

EDIT: Nevermind, figured it out. Had to force power down with the download mode key combo instead of just power button, booted to recovery just fine on reboot to wipe and booted just fine afterwards.

Double Tap to Wake fix doesn't take if you're restoring from backup.

For the second item, I've found that clearing storage for the PhhTrebleApp in Settings->Apps & Notifications-> See all XX apps->Show System works around the problem.

On the bright side, the 3am reboots no longer seem to be happening.

Newbie Help

Hi All,

Apologies, I'm relatively new and I'm rather confused by a few things.

1. My T510 was running Android 9 - was I supposed to flash LOS16.1, or was it ok that I used LOS17.1? I was under the impression that it didn't matter what version on android is on my device since it's getting replaced anyway.

2. I'm not able to encrypt my device. Go into the settings, click on encrypt, click through both prompts, I see the android logo, the LOS logo and then my device boots up.

I'm reading, what I perceive to be, conflicting info - some say that the BL (TWRP) has issues with encrypted devices? Otherwise, I'm reading that you "simply" make the main partition smaller by 16kb, and then encryption works. I'm rather lost as I'm not sure what's accurate. I assume just a password on LOS isn't enough for proper device security. Perhaps my own lack of knowledge makes me feel more secure with device encryption.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] massivekind:
1 indeed, it doesn't matter. Let's see it as an unofficial Android update;)

2 if you unlocked your device and installed the multidisabler and also formatted the data partition, then your device is not encrypted anymore. Without the multidisabler your where not able to see in lineageos your documents or photos via an file browser
