Indeed I overlooked this detail when I wasted a whole day a couple of months ago trying to flash android 10 roms. Then gave up and settled with android 9 and continued with my life. And I overlooked as well that the first page has links to stock roms. Albeit at extremely slow download speeds. So I spent 5-6 hours downloading a ROM ending with BUA1. Flashed with Odin. Then flashed the latest Nexus ROM Tarball in AP. And finally works. amazing.. Thanks for the help you guys!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Gamris:
And your exact instructions that you gave to someone on Page 30 of this thread really helped.

Hi - first thank you and the community for all the work and great content here.

I spent the last few hours trying to get this installed and I don't think it's going to work for me because my tablet is already on the next level of the official firmware and downgrades aren't allowed. I would love to know if this is WRONG so I can keep working on it :)

My tablet is on the T510XXS5BUC4 (the version after the one this rom is based on.)

I understand that I need to downgrade to the *BUA1 stock firmware before flashing this ROM.

When I try to do that, Odin fails and I see the following on the tablet screen: SW REV. CHECK FAIL (BOOTLOADER) DEVICE: 5: BINARY 4.

From my research, I believe this is because the boot loader prevents downgrading, so it's not possible to downgrade the official firmware (which in turn means I can't flash this rom.)

I guess my only option is to wait for the version of the Nexus rom based on *BUC4 to come out.

Am I thinking about this correctly or am I missing something?

Thank you again!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] -BoneZ-:
From what I've read, it's not possible to downgrade. The OP has been pretty good about getting updates out, so just hang tight. I went back to the stock Samsung ROM and it's just as fast as this ROM.

I'm attempting to install via Heimdall on Ubuntu. Yours is the second ROM I've tried to install and I'm running into the same problem: The recovery install "succeeds" according to Heimdall, but the device then circles back into a fake version of download mode with the error "recovery: Error validating footer (6)".

That's the best result. I get it when flashing your recovery, and I get it when flashing (some) TWRP recoveries directly. Others, including a supposedly "stock" recovery and one from LineageOS 17, fail on flash.

The bootloader is unlocked, USB debugging enabled, all that jazz. I don't understand why this is happening. Any guidance would be appreciated.

I am getting an error that the firmware file you're trying to flash is binary or bit 4, device current firmware is bit 5. You need to find firmware with bit 5 in order for the flash to go through. What should I do?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] vlrgamaley:
You can`t do nothing with it. Magedanz need to rebuild or set another bulid which will be based on kernel of T510XXS5BUC4 or something like that.

@Magendanz, can you rebuild or build that ROM on the kernel of stock ROM which has bootloader number 5? Or you leave development of A10 Nexus Stock?

As i noticed, Nexus10 ROM by you is more stable and haven`t big bugs unlike as your Nexus11 ROM, really? If it`s true, I think many users which were updating on stock A11 will be grateful if you take this N10 ROM on bootloader 5 and we can go to downgrade to A10 and then install N10....
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I'll take a look at updating with a more recent OEM firmware release over the weekend, but I will be dropping support for this as soon as AOSP12 and CAOS12 GSI releases begin.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Okay, so it turns out that the T510XXU5CUF4 OEM firmware release is an Android 11 kernel and it won't run any of the Android 10 GSIs. I tried both CAOS and LineageOS, and they wouldn't boot. Everything based on AOSP11, however, is still chugging along fine.

Might be time to put this one out to pasture, folks. :-(

Can I do it all through TWRP? 🤔

If so which wipes do I do before flashing? 🤔
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
If you're coming from the Android 10 OEM firmware (Bxxx), then you'll need to first install the latest OEM firmware and then this custom ROM via Odin. If you're coming from an Android 11 OEM firmware (Cxxx), then you probably could upgrade via TWRP and the data wipe is optional.

The safest bet is always to do an Odin flash of the latest OEM firmware and then install the custom ROM via Odin, but this always does a factory reset.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:
Thank you very much for all your work in general & help now :)

Regrettably I'm in trouble I can't seem to get back into TWRP or Download Mode or even power the tablet off: https://xdaforums.com/t/rom-sm-t510...-galaxy-tab-a-10-1-2019.4060153/post-86264395
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Unless you corrupted the bootloader, you should be able to get back to Download Mode. Just connect to your PC via USB, press and hold Power + Vol Down for 7-8 seconds, and quickly switch to Vol Up + Vol Down. It may take a few tries, but there's no need to wait for the battery to deplete.

From Download Mode, just flash that latest OEM firmware with Odin and try again.

(I can't speak to the Magisk issues that you were running into, since that's really not my area of expertise.)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:
Woo hoo success!

I got it into Download Mode thank you so much I thought I ruined this tablet that's why I was nervous to go upgrading it at all.

I'm downloading the Android 11 OEM my my I haven't messed with Odin in a long time.

There's a guide floating around somewhere for how to use Odin I don't just put the entire downloaded image in AP do I?

Oh that looks like exactly what I might do from this info here which is admittedly the custom rom instructions but I'm guessing it's the same with this OEM download?

Install custom ROM tarball (.tar.md5 file) to AP with Odin
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
No, but you can't flash twice in Odin. You'll need to reboot and hold Vol Up + Vol Down to reenter Download Mode. After the custom ROM, I usually reboot to TWRP to do a factory reset just to ensure the user data partition is clean and unencrypted.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] y0himba:
I was unable to get any Gapps to work with the latest 18.1 in the original post, so had to install the Nexus ROM by the same creator.

Good news is, the Nexus ROM is running smooth....

It's sad there are so few ROMs for the SM-510(2019). I love messing with new ROMs and this device is still pretty powerful even today. Someone should start a project for slightly older devices like this, that still perform amazing.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kenaz Rune:
Yeah, and I wish there were a good port of a kernel like kirasakura. Unfortunately, @megendanz is the only person to take interest in this device, and thank the gods he did!

It's too bad that it seems there won't be an update to A12, or even any further security patches.

At least Andy Yan's LineageOS 19.1 GSI works. I just had to come back to this version as well because my lineage GSI somehow got fubard with the last update.

It's a testament to @Magendanz's work that all I have to do is come back and flash his stuff and my device works again.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
This could happen if OpenGApps is updated for A12. Because of the long lag times for new OS support, I've been considering switching to NikGApps, but not on this device because they don't have ARM32 support.

To keep this device going, we really need to be converting a vendor partition from another Exynos 7904 device with ARM64 firmware like the A40. I'm sure it's possible, but I just haven't had the time.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] CarinaPDX:
I appreciate your past efforts but at this point the effort grows exponentially. Samsung's policy of forced obsolescence by not providing OS updates beyond the first year or two makes support increasingly difficult and is not something that we should be supporting with our dollars. Not documenting their CPU, API's, and designs while hiding so much in binary blobs is intended to force buying new hardware. As good as their hardware is I think we are better off putting our efforts into supporting other tablet manufacturers, if any can be found that will support open source. Perhaps there will be new Google tablets that fit the bill. I'm done with Samsung.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
But exFat isn't supported "out of the box". Yes, some devs have patched their ROMs to fix the problem, but this one hasn't. And it may not be important enough to them to bother. Is it really necessary to you have files larger than 4gbs?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] henslayer:
Frankly, I don't care in which file system the card is formatted. But when the OS itself pops up an error and attempts to format the card it fails repeatedly. Why would the OS try to format the card in a FS it does not support?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Because it's dumb.;) Every progammer has found out the hard way that programs never to what you want them to, but only what you tell them to. It is trying to format as exFat because it is larger than 32gb but then the installed kernel doesn't support exfat so it fails. Stop fighting it and either use the app I linked above or choose another ROM.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Is anyone else having this problem or have I done something wrong? As I posted, I even tried a full wipe before flashing, let google reload all my apps from the cloud and then tried backing up again. Same createTarFork error and backup fails.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ouaisem:
From my side I need exFat because of the go pro and the mavic and a sony camera.

These use exFat formated card I suppose because of the 4K video.

I sure can format their cards in FAT32 but it less efficient for 4K video.

A 64Gb card FAT32 formated works well with last 0312 ROM.

I suppose 512Gb or 256Gb used by other guys here are also FAT32 formated.

If this is not the case I maybe do something wrong during flashing or after.

But it's not blocking for me as exFat works fine with the 0223 ROM. So I stay to this ROM for the moment.

Thank you.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] henslayer:
I'm not going to install a program on a swiss cheese Windows machine from some random source. Advice is appreciated, commands are not.

Meanwhile, I did some experimenting. I have a little Windows box that I use for some stuff that requires it or is easier to do that way, but mainly I'm a Linux guy. I pulled up the man page for 'mkexfatfs' which includes the line 'Note that if this is an MBR partition then the file system type should be set to 0x07 (NTFS/exFAT) otherwise other operating systems may refuse to mount the file system.' So I opened it up with cfdisk to check and yes, the partition was listed as 7 NTFS/exFAT (and HPFS?).

Just for the heck of it I decided to GPT partition it with cgdisk and used 0700 for the partition type. Then I formatted it with 'mkexfatfs -n Android /dev/sdi1'. No big surprise that it didn't make a difference. 20200312 still cannot see it and 20200223 still does. Well, it was worth a shot.

Ideally, they could use an unencumbered Linux file system like ext4 or btrfs. It would make a lot more sense. After all, it is a Linux kernel at heart, though heavily modified. Isn't the main system partition on Android ext2?

Just out of curiosity its not possible to create a flash zip rom for TWRP or something like other roms.

But I would like to say thanks for your hardwork for the community though.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
That may be, but it shouldn't matter. You really only need to ensure the vendor, product and system images all match...and those are included in the custom ROM tarball. At least, that's the case for the SM-T510, which doesn't care about modem images and such.

Seems to be an issue from the Disney app. Try uninstall the app, reboot and install it again.

https://answers.microsoft.com/en-us...9/5d17c80b-4db1-4436-9101-1c122a68e426?page=1

If that doesn't work, try to fix the ctsProfile: false SafetyNet check. To do that first install Termux from PlayStore, then open Magisk/Downloads and download and install MagiskHide Props Config and Busybox. Reboot your device, open Termux and enter the following commands and confirm with enter:

su

props

The MagiskHide Props Config script should show up. Choose:

1

f

20

40

and confirm with y. Reboot and now you should pass the ctsProfile check. Also try to add the Disney+ app to Magisk Hide and retry streaming on the device.

Yes I can confirm this. I'm now on the LineageOS build and the reboots still occur. First I thought it's because my device is rootet, but I think yours isn't so that can't be it. Just ask if I should try something to figure this out.

Did you wipe the data partition? Also, the latest OpenGapps is already baked into this custom ROM, so installing it again might be problematic. (It will at the very least replace my custom version of the Pixel Launcher, which restores the old profiles for the Nexus 7 and Nexus 10 tablets.)
