Hi all - I hate being that guy but...

I thought I was updating my rom Nexus_Stock_AQ_T510XXU2ASK5-20200410 to the latest version... but I wasn't paying enough attention.

Since it was an update I wiped dalvik + cache and tried dirty flashing:

Nexus_Stock_CR_T510XXU3BTK1-20210216.zip

Sure - now I see it... but I didn't realize it then - I apparently dirty flashed Android 11 over Magendanz Android 10 work.

It didn't work... Then I did a full wipe and tried installing again ... probably shouldn't do that.

Then I did another full wipe and tried installing Nexus_Stock_AQ_T510XXU3BTH4-20201130 over this mess and now I am getting: Updater process ended with ERROR:7 in TWRP 3.4.0-0

Actually no matter what I try and flash I get this error. Actually - as brain dead as I was - I may have gotten this error at step 1 above...

I did a full TWRP backup before starting all this - did a restore and - it goes into a first boot loading logo. I let it cook for 30+ minutes and still didn't boot.

Not sure what to try next.

Thanks in advance,

Okay - Deep Breath....

I tried restoring my backup again and somehow this time it worked.

You know that feeling you get when you think you just bricked your favorite tablet?? That is just now starting to go away. But I'd be happy to hear what I am doing wrong above...

And Magendanz - Dude your ROM rocks.

Thanks for all the hard work
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Hi - back at fiddling and don't know what I did wrong this time. I updated TWRP to twrp-3.5.0_9-0 and tried installing the Nexus_Stock_AQ_T510XXU3BTH4-20201130 again.

That didn't work. I did not get Error Code 7 though...

But now I am back to trying to restore my backup and it is just not working...

Check my work -

wipe all,

format data - yes,

restore: system, vendor, product and Data

then reboot and enjoy?

Or - since my backup was made in Twrp 3.4.0-0 do I have to install that version of twrp recovery to get that backup to work??
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Try restoring only system and data.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Thanks @lewmur - but that doesn't seem to do it.

Just cooks at the G symbol with the moving progress bar. I believe when the restore worked it took less than 3 minutes. This is at 15.

Yep - @lewmur was on the right track... I did a restore choosing only BOOT, system, vendor, product and data. I think Boot was the

key - but really a guess on my part.

Getting everything set to move on to the 11/30/2020 update.

Thanks again

14 March 2021 Update -

This is exactly what I did to move up to the latest base firmware. Everything seems to have gone okay.

Getting set to move forward. I read this thread top to bottom from the beginning now and I see what I did wrong. I have not updated to the proper base stock firmware... So to help me and my short attention span and anyone else getting set for this upgrade - I wrote out exactly what I think I need to do:

Download T510XXU3BTH4 stock firmware from Sammobile.

Helpful tip - looks like the USA file from Samfrew site will take about 6 hours if you want a free download? But the UK file from Sammobile took less than 5 minutes? Comparing checksums - they are identical.

Unzip that into a folder revealing a number of files ending in .tar.md5

Install or update Odin to 3.14.

On the tablet make sure Developer Options are enabled along with OEM unlocking and USB debugging.

Now is a good time to make a complete backup in TWRP if you don't have one.

Boot the tablet into Download mode: With the tablet powered off - Hold Vol Up & Vol Down buttons and connect the USB from tablet to laptop. It will boot to a teal colored download mode screen. Press Vol Up to enter download mode.

In Odin Click BL and find the file from step 2 that starts with BL_T510 and click enter. It will verify the MD5 checksum but once confirmed - then do the same for the AP and CSC button.

For the CSC button use the file starting with CSC_*** if you want to do a clean flash

For the CSC button use the file starting with HOME_CSC_*** if you want to keep your apps and data. It won't install your apps in the new install but it won't delete the data.

Click start and allow it to write all these partitions to the tablet.

When it completes it will automatically reboot. Press Vol Up + Vol Down and Power all a the same time to force the tablet to power down.

Then reboot directly to Download mode again (See number 5) and open Odin 3.14 again.

Click on AP and find the Magendanz BTH based custom rom of your choice (Nexus_Stock_AQ_T510XXU3BTH4-20201130.tar.md5 is my choice) and hit enter. Odin will verify the MD5 checksum.

Once verified - click Start

When complete follow the on-screen instruction to power down the tablet to exit.

Reboot the tablet and enjoy! First boot may take up to 10 minutes.

If you want - reboot to recovery and Restore your System partition (ONLY) from the TWRP backup you did in step 5 above. Now all your apps, data and settings should be back.

Hope this helps any who follow that want the Awsomeness of @Magendanz 's ROMs

Thanks again!!

Hi again - No thoughts on my step by step above? Am I not supposed to ask how before I start?

Next question though - Screen Cast doesn't seem to work. I can cast from my cell phone to my living room easily. But on the tablet it never finds any of my TV's.

Thanks again,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kenaz Rune:
I am using this ROM and can cast just fine. Sorry I can't comment on your steps. I did the initial install over a year ago. I can say that you need to start from a recent stock image.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Thanks @Kenaz Rune - I did my first install a while ago too - so sadly part of this is I am just getting too old to remember too.

Also - thanks for letting me know that Screen Cast works. I am hoping this update fixes that for me.

A new release was just posted. Note that I've switched to @eremitein's CAOS as my base GSI. All of the one-off patches that I was applying to the AOSP GSI were from him, and he's done a great job collecting a clean and elegant set of tweaks on AOSP that make it much more like a Google Pixel or Nexus release.

Is this version equal to your Android 11 release?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, it's Android 10 instead of Android 11, and it doesn't have the cold charging issue. Theme support is better integrated on Android 11. Otherwise, they're pretty similar.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sr1sws:
I have the previous version running on my Tab. I'll plead NOOB - can I download and install via TWRP? Does this essentially wipe the device, requiring a complete re-setup and re-install of apps? Thanks for the indulgence... and for providing the software!!

Great rom and by far the best I've used in the T510. So fast and responsive compared to the factory rom.

Looking forward to the cold charge fix when you get time. I'm sticking with this rom for a while :D

Has anybody else experienced problems downloading, updating or installing from Google Play Store?

I was very limited on OEM ROM (but with TWRP & Root) so installed this ROM (now still TWRP but no Root) and still can't install most Apps on the Store.

Love how responsive this ROM is compared to OEM but the Store issue is driving me daft! Will I have to Odin the default recovery back in?

Cheers, Glyn (glyn.royds@gmail.com)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] henslayer:
Well, my new tablet arrived today. I was going to wait a couple days for the update on this ROM, but I got impatient and flashed 20200223 since you said that a dirty flash would be okay with incrementals. Everything went smoothly. It runs great, sees my exFAT SD card and Magisk installed without issue.

The only thing I don't like, and I should have foreseen this because it's basically a Google stock ROM, is that I can't get rid of that damned search bar on the home screen. I even installed Smart Launcher (the free, no-ad one), which I use on my phone for just this purpose. It works great on LineageOS, but on this ROM it simply will not run. Does anyone know how to get rid of the Google bar?

Anyway, other than that it's awesome and I thank you very much.

Also, can you tell me what is the difference between the version that's based on Andy's latest build of LineageOS 17.1 and this one?

Never mind. I tried LineageOS 17.1 and like others could not get any gapps to install. Then I tried the Nexus ROM based on Lineage 17.1 and it didn't like my exFAT SD card, plus the same launcher issue. So I went back to this one and installed Nova Launcher. Good riddance to the Google bar and everything is working fine.

MTP file transfers no longer require USB Debugging to be enabled.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] FL0R1AN:
Just installed version: 20200312.

I had a little problem after the tablet rebooted to the system, the touchscreen was unresponsive. I formatted the data in TWRP prior to booting to the system. I pressed on volume and power buttons just to see if the tablet was frozen and they were working fine. It turns out when I pressed Power Button to lock the tablet on and off then the touchscreen became responsive. :/ If anyone encounters the same problem try to lock and unlock the screen by pressing Power Button. It worked for me.

Everything works fine so far. Great work as always. Thanks for the wonderful ROM.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] henslayer:
I just flashed the zip update, wiped Cache/Dvalik and rebooted. All is good except the SD card, which is the same one that was working flawlessly before.

Now I get 'Issue with SanDisk SD card Tap to fix'. So I do that and it wants to format the card, which I allow it to do. It says 'Your SD card is ready to use'. I click the Done button and it goes right back to the same error message in the notification bar. And BTW, when I'm in the Format dialog, the option to use it as phone storage is grayed out and only Portable Storage is available. Regardless, it does not work at all. Even if I go into Settings > Storage it shows up as 'android Corrupted'. If I tap on it and go to 'Set up' it takes me back through the same failed loop.

I've taken the card out and cleaned the contacts, rebooted, etc. No joy. Any ideas?

All I can say is that my 256GB Samsung EVO+ microSD card is working just fine. Anyone else having external storage problems?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yes, I noticed the same problem with the plain LineageOS 17.1 GSI 20200309 build, so I assume it's just a bug that's on their radar. (Note that I wasn't able to reproduce it with the AOSP 10.0 GIS.)

I have a 512GB EVO Select that I bought just last month along with a new A70 phone. I see that the price on the Plus is a few dollars higher so it must be a step up from the Select. The SanDisk is one I had lying around and I'm not sure how old it is, probably a year or two. Maybe that's an issue, but in the same device with the AQ 20200223 ROM it works just fine. On either LQ based ROM it does not. I'm baffled.

Maybe I'll buy another EVO, but for the mean time I've reverted to 20200223.

---------- Post added at 01:37 PM ---------- Previous post was at 01:35 PM ----------

That is exactly the same thing I see. Maybe it's because it's a slightly older SD card, though a decent one.

Is it possible to downgrade to the android pie OEM firmware from this rom without losing all data via odin?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ouaisem:
Hi,

LOS doesn't support exFat.

I think that's why many of you have issue with SD card using big capacity larger than 32 Gb.

---------- Post added at 03:12 PM ---------- Previous post was at 02:58 PM ----------

By the way exFat works with TWRP at least with a key mounted using USB OTG.

And above all, thanks for the great ROMS.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
There is a partitial cure for this. It won't allow files any larger than regular FAT32 but it will allow partitions larger than 32gb. http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm To download it, click on the picture and not on the highligted link. This is a Windows app, so you have to format the SD card on a Windows computer.

You should just be able to install an incremental update like that via TWRP with the .zip file. No need to format the user data partition.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] renegvera:
For the installation I followed the tutorial that is on the first page of this topic, from the official Samsung software using odin. I saw on another page of this topic an instruction manual in which they mention that a full wipe must be done after installing this rom for the first time, which would logically eliminate the rom that I just installed, so it would have to be flashed again by odin and it could already be used, I think it was necessary to remove a Samsung encryption. Could this be the mistake I'm making? Since I did not do this step of the full wipe, but only factory reset as mentioned in the tutorial on page 1.

I would appreciate if you could guide me to do it well, since the rom itself works very well and I love stock Android.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
If you're installing for the first time (or the first time after running the stock OEM firmware), you'll need to do a factory reset with Wipe->Format Data in TWRP to get rid of the file-based encryption. Doing that should be enough to get you back up and running.

Since I'm constantly testing different custom ROM builds, I'm a little more thorough myself. Here's my routine:

Hold Vol Up & Vol Down buttons during restart to enter Download mode

Install stock OEM firmware (BL, AP & CSC) for underlying build (e.g. T510XXU4BUA1) with Odin

Hold Vol Up & Vol Down buttons during restart to reenter Download mode

Install Nexus custom ROM tarball (.tar.md5 file) to AP with Odin

When TWRP launches, factory reset with Wipe->Format Data.

Reboot to system

Note that I don't even allow the device to reboot to the stock OEM firmware after the first flash. To do this, you either have to be ready to hold the Vol Up & Down keys as soon as the flash completes, or you need to disable Auto Reboot in Odin and initiate it manually by holding Power & Vol Down for > 7 seconds. If you miss your window and it boots into the OEM firmware, Samsung's VaultKeeper "feature" could initiate a stealth bootloader lock. To avoid that, connect to the Internet and immediately enable Developer mode and confirm the OEM Unlocking setting in Developer options before you reboot and try again to enter Download Mode.

I have followed these steps and have not had the storage problem again. Thaks so much for the orientation!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Broman400:
Was wondering if there’s an audio enhancement in this ROM similar to the stock ROM?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
In Settings > Phh Treble Settings > Samsung features > Misc you can enable stereo audio mode, but other than that the options are pretty limited. LineageOS at least had an AudioFX app that you could use to boost volume. You could try migrating that over.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] brickquinn:
Hi, thanks for all the hard work. I installed the rom and in general it worked fine.

I couldnt install Netflix and the play store reported the device as not certified for Play Protect. Is there a way to get past this? or did I do something wrong in the flashing process?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
The AOSP GSI does some basic fingerprint spoofing to allow devices to use the Google Play store, but you're not going to get Play Protect certification with an unlocked bootloader (nor should you). If you want to experiment with some more robust spoofing methods for Play Protect, though, I recommend you look into installing Magisk.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] brickquinn:
Thanks for the quick reply. I will look into Magisk. thanks for the tip. That actually leads to me another question, and I apologise flashing roms is new to me. After flashing this ROM can or should I be looking to lock the bootloader again - or is that even possible and/or make sense?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
If you lock the bootloader then everything is wiped. Make no sense with custom ROM.

Guys. I'm trying to understand why absolutely any android 10 rom gets stuck on boot screen after flashing, for example for this nexus rom it gets stock on that Google boot animation. The only roms that work on my SM-T510 are android 9 roms. For example Lineage OS 16.0..... Any ideas on what's wrong? I wipe pretty much everything and tried everything and they're always just on boot screen for hours. AND it doesn't matter if I flash it through ODIN or TWRP. Same result.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Sounds like you didn't update to the Android 10 OEM firmware release (BTU-T510XXU3BTFN or later).
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] -BoneZ-:
I'm having the same exact issue. I'm coming from an earlier version of this ROM. I updated TWRP and after installing this ROM, stuck at the "G" logo forever loading.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
That is because Samsung changes the partitions and you have to first flash the stock ROM to match the version of the custom ROM you are trying to install. If you look in the first post of this thread, you'll see that this one is based on stock ROM ending in BUA1. That is what you need to flash with Odin, reboot and connect wifi, skip the rest of the setup and enable Dev mode. Then you can flash this ROM.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] -BoneZ-:
Yep, I flashed newer firmware and then flashed this ROM and I'm in now. Technically since I was on a previous version of this ROM, I was following the "incremental update" instructions, but we're good now. :)
