Try to put the USB cable directly into a socket in your computer, and not using a USH hub or something. I had the similar problem, and it was solved when I put the cable directly in my computer.

This was posted by beetlehov, credits to him, I do not if this will work, he says it worked for him.

Found the solution

Start the upgrade program at xp. Confirm the security information at the device with yes. uncheck USB Connection in Active Sync.

if you read the post regarding flashing Hard-SPL, they mentioned that if you have trouble with it, copy SSPL.exe to your phone and manually run it on your phone. Your phone will go to a black screen.. then run the RUU for HardSPL.. your phone should be connected via usb while doing this.

Hello,

I have Tab A 2019 & I need to downgrade Sm-t510 from Android 9 to 8..Any help please?
[Samsung Galaxy Tab A series Questions & Answers] secretwolf98:
A) why do you want to downgrade from 9 to 8?

B) the tablet came with Android 9, it’s not possible to downgrade to 8.
[Samsung Galaxy Tab A series Questions & Answers] Jasmin74:
I could do it from 8 to 6 on other tablets - like tab A 2016 sm-t580
[Samsung Galaxy Tab A series Questions & Answers] secretwolf98:
That's because the SM-T580 model came with Android 6.0.1
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
is there any custom rom based android 8 for this device? my device has 2GB ram and now updated itself to 11 but it gives me cancer almost garbage now..

i found a android 9 stock rom but i wonder what else can do? i know that android 8 works well with 2GB ram. any custom rom for this device suggestion should be perfect for performance usage. thanks regards
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
There was never a stock OR custom ROM based on Android 8 for this tablet. There are many others, including myself, happily running Lineage 18.1 with only 2gb of RAM. Maybe you just need to do some de-bloating.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
i used a twrp then the device stucked. waited a day long to drain battery now which twrp version is good for this device?
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
The version linked in the OP.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
what does it means OP dude?
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
I'm 82 yrs old and my generation doesn't like the term "dude". OP stands for Original Post. It is the first post in the thread and it is ALWAYS where you should start reading. It will have the instructions and the download links you need.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
The order I tried but did not get any results is as follows;

1- I installed the latest rom released by samsung which is android 11 with frija tool with odin and the device returned to its normal state.

2- I'm logging into the system with this official latest. I activate the developer options and activate the oem unlock. resets to factory settings. I pass the android welcome screens again and turn on the system. I am connecting to the wireless network. I go to developer options and see "oem already unlocked". When I restart the device to check, I get the "device unlocked" warning and I'm sure about the unlock.

3- After this stage, I tried to write this file "twrp-3.5.2_9-0-T510XXU5CUF4-20210725.tar.md5" with twrp by entering "download mode" with odin. when i try this, i get an error like "only official install is available" or sometimes it installs twrp in a way that i don't understand.

4- If twrp is installed, I install the file named "multidisabler-t51x-1.41.zip" by first doing twrp format&wipe, but the device never opens, so it gets stuck.

5- Or when I enter "download mode" with twrp installed and want to install android 10 or 9 stock rom of this device that I downloaded from SAMMOBILE, I get a warning "KERNEL ERROR, DEV 1 BINARY 3 etc.. I also tried linage and nexus roms. When twrp was installed they gave the same "KERNEL REV." errors.

What could I be missing at this point? I would be glad if you help me. I've been trying for 2 days with no results.

My main goal is to get rid of android 11, but obviously they put a "downgrade" barrier and how can we overcome it.
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
You have to go through the vbmeta install proceedure before you can install TWRP.

[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
how can i get the documentation of this stuff ? "vbmeta install proceedure"
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
I apologize for my way of speaking, Mr. Lewmur. im translating my words because my english not necessary for this type for chain tasks and tasks that require patience :)
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Go to the ROMs, Kernel, Recover section on how to install Nexus Stock ROM. It will install both the vbmeta and TWRP along with the ROM. If you don't like that ROM, you can then install what you want via TWRP. Just remember to format the data partition when it first boots to TWRP.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
also i edited now my this post and removed "dude" word :)
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
mr lewmur, Is there a way to install the android 9 rom that I downloaded from sammobile instead of Nexus? i mean downgrade 9 from 11 ( T510XXS2ASK1_T510TUR2ASI4_TUR)
[Samsung Galaxy Tab A series Questions & Answers] blackhawk:
Android 8 is vulnerable to that nasty "immortal" rootkit.

Pie is a good OS and is immune to the uninstallable rootkit variants.

I wouldn't go less than Android 9 or more than 10...
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
No. You can't downgrade. And the Nexus Stock ROM isn't really stock. It is a custom ROM meant to feel like the Nexus ROM.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
This is the main reason I got into this business. I'm using firefox and when I switch between applications, data in all tabs is reset. So whatever I'm watching, the video takes it to the top instead of where I left off. whatever I was reading on the other tab, the page was refreshing and the place I was left off was disappearing.

but my mobile phone with android 11 does not have this problem. my cell phone is samsung but i have 6gb ram. I also use firefox on my mobile phone.

Before I started to deal with this tablet, I examined the parameters related to hardware usage. even when the device was idle, it was using up to 1GB of ram and almost half of the CPU.

Also, when I looked at the android 11 system requirements published by google, they wrote that the ram should be larger than 2GB, but Samsung is upgrading the devices to 11 without caring about it. They are making the devices garbage so that a new one can be purchased.

At this point, as far as I understand, "downgrade" cannot be done. I will have to install nexus or linage.

If you have any information about the firefox problem I have experienced, can you tell me which custom rom will I have less problems with?

linage or nexus? I want to install old versions of these two custom roms. Like 16 instead of 17.

I would appreciate it, Mr. Lewmur, if you could share your experiences and ideas on these matters.

In summary, my goal is to access internet-based content on the device more than once, to conduct research. During these researches, the results such as refreshing the tabs bother me a lot. I forget where I left off or I can't make progress.

Thank you in advance for your understanding.
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
I don't use Firefox, so I have no idea what the problem is. Google might "recommend" more than 2gb but Android 11 runs fine with it. And with rooted custom ROMs you can remove a lot of google and samsung bloat to reduce the amount of RAM needed.

edit: But you can't get around the fact that a device with 6gb is going to allow you to open more tabs than one with just 2gb
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
ok. thanks. i just tried install multidisabler through twrp but i get "mounting system attempt failed.." error. what can i do now any suggestion?

[Samsung Galaxy Tab A series Questions & Answers] lewmur:
If you installed the Nexus ROM, you don't need multidisabler. Just flash Magisk-v21.4.zip to get root.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
when i enter twrp and try to install magisk.zip i get "unmount" error again.
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Is it v21.4 that is found here? And did you FORMAT, not Wipe, the data partition?
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
yes i formatted also tried resize/repair and reformat as ext4 all partitions but doesnt work
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
I have no idea what refomatting all of the partitions to ext4 has done. I'm surprised if it will boot at all after that. And you only need to resize if you are trying to flash gapps and it fails. But since the Nexus ROM already has gapps, that shouldn't be a problem. Will the tablet boot to the setup screen?
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
ill try thanks again
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
lewmur can you send me exact link of installation nexus documentation. i really tried and confused sir.
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
If you haven't already, download the latest stock 11 ROM for your region from here. Flash BL, AP and Home. Home should flash from CSC. Boot to setup and connect to wifi. Skip the rest of setup and enable Dev mode. Check OEM unlock enabled. Reboot to download. Download Nexus ROM from here. Flash from AP. When it finishes, it should boot to TWRP. Format data partition only. Boot to system and setup the tablet. Enable Dev mode. Reboot to TWRP and flash Magisk v23 zip found here.

ill try sir thank you

Android 11?🤭🤣🤣

This will end badly... 10 is the highest I would go unless you savor the smell and taste of green Android puke.

You will lose app functionality.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
yeah the device dead now :/ if i can i will install android 8 to this device. do you know any method to downgrade 9 for this device. i have original 9 stock rom but i get kernel error when i try to write this rom. i think there is a barrier for downgrade.
[Samsung Galaxy Tab A series Questions & Answers] blackhawk:
The boot loader version. The 5th digit in on the numbers must match or the rom version's significant digit must be higher than the boot loader's. I think that's how it goes... I avoid doing this. If it was loaded with Pie the boot loader likely wouldn't allow the downgrade.

Be happy with Pie unless there's a glaring specific issue that makes it unusable. There's no cpu cycling sucking scoped storage on 9; it appears to still be dormant in 10 but it's there.

Android 10 may run better but don't count on it. Both look very similar on my N10+. On 10 overlays don't work and Karma Firewall's valauble logging doesn't work.

If I was you I keep Pie and stop playing with it before you brick it or end up with a less capable version.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
the device already updated yourself to 11 buddy. i cant downgrade to 9. my question was how can i downgrade i mean is there any move like this?.

now im installing nexus with lewmurs guidance but also wonder downgrade thing.

regards.
[Samsung Galaxy Tab A series Questions & Answers] blackhawk:
If the boot loader was upgraded, no.

If it was a OTA update it's possible the boot loader version wasn't updated, check it.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
guys i installed nexus but when i try install a app from play store says no storage space and i cant. when i check storage section seems fine. what is the probem? thanks again
[Samsung Galaxy Tab A series Questions & Answers] blackhawk:
Clear system cache.

After a major firmware update do a factory reset.

Now you know why I leave sleeping dogs rest...
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Ever heard of the term FUD? Unless you can give specific examples of problem most people will face, and not just one from some app you consider important, then, IMO, that's what your comment is. There are many, many people using Android 11 without any problems. Other than yourself, I haven't heard complaints from anyone. And it certainly does no good when someone has already upgraded to 11 and can't go back.
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Go to /Setup/Apps and notifications, and start deleting apps you don't use. Then reboot.

edit: Also, go to /Setup/Storage and see how much storage you have left. You should have around 20gb left of the 32.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
ill try thankss
[Samsung Galaxy Tab A series Questions & Answers] blackhawk:
Scoped storage.

You like big sisters and Karens?

Having to repeatedly grant permissions?

Ever hear the term fubar?

storage : 6.5GB used of 32GB

i cant uninstall any app also i noticed all installed app natvie apps youtube chrome etc. but icant install anything storafe error :/
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Well, you are obviously not out of storage space. Are you sure you formatted the data partition and not just wiped it? Open up the file app and look at the folder names. Are they garbled?
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
files app says, "cant load content at the moment" i think somethink read/write or access error of partition or somethnk
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
This is the behavior I would expect from not formatting the data partition. Reboot to TWRP. Select Wipe. There will be two buttons at the bottom of the page. One says Advanced Wipe and the other says Format Data. Choose Format Data and then type in yes and then enter. All three letters and not just y. When it finishes, keep hitting the back button until you can choose reboot and reboot to system.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
when i try format and typing yes then i get "unable to mount"
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Never heard of that before. All I can think of is that when you reformatted everything to ext4 you somehow messed up the permissions. Try /Wipe/Advanced Wipe and check the Data box and select Repair or Change file system and then Repair File System.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
now its ok sir its working

it worked but..

still the pages refresh when I switch between apps. I can't go back to where I left off in the tabs in the internet browser. Is this not a problem for you?

for example, you are reading an article in chrome you are on page 10, then you switch to another app and do something and you come back and chrome refreshes the page. everything is reset.

This was not the case when I first got this tablet. I think it came with android 11. and i realized that even nexus android is 11. and even on nexus, it still uses 1.5GB ram when the system is idle.

my mobile phone is samsung and 6GB ram is still android 11 but this is ok. It doesn't keep cache because obviously system resources are insufficient. How do we solve this guys? Since I'm working multitasking, the tablet doesn't work for me. that's a waste of money.

to be honest this is bull****. Even if I install the oldest android on a hardware with 2GB of ram and many cores, it should be possible to switch between 10s of tabs. I wish I could install android 7-8 but obviously not possible.

I am open to your ideas. Thanks for your support. especially mr lewmur thanks for your patience and support. Your attitude and knowledge are invaluable.
[Samsung Galaxy Tab A series Questions & Answers] dedeoglumrt:
sir lets fix this refresh problem with me and documentation together :)
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
If it is using 1.5gb then you haven't debloated it. Mine is using less than 1gb. How are you switching between apps? Are you using the "recent" button or are you going back to the home page and relaunching the app? If you are relaunching, then that may be your problem.

Ultima is a TouchWiz-based ROM that brings newer experiences on an old, stable software. A spin-off from a very hopeful "The Hedge Project", Ultima is a revival of Hybrid Development Team's most popular ROM, Miix.

Like the project's codename, 'Project Shadow', and the character of the same name from the Sonic the Hedgehog franchise, Ultima's base is old, but remains strong to look young.

Beautifully One

Ultima follows Samsung's latest One UI guidelines. Rounded corners, easier one-handed use, and the beauty of dark mode (coming soon).

Picture-perfect

From icons, design, to the lock and home screen. Ultima is beautiful and elegant inside out.

Updated and Ported Apps

Thanks to a lot of contributors to the project, Ultima includes authentic Samsung apps from the latest Galaxies.

Truly Flexible

Ultima is the most flexible ROM yet, with theming, icon, plugin, and wallpaper options out of the box. Not to mention Magisk support on the get-go, adding more possibilities of modding Ultima to your liking.

Updated Direct

Like its heritage, Ultima updates over-the-air with the only things it needs, saving your data, space, and time.

More Features

- OneUI-styled apps, from the lock screen to the SIM menus
- OneUI-styled SystemUI (notifications panel and status bar)
- Samsung TouchWiz launcher from Samsung Experience 8.0
- Calculator app from SE 8.0, styled to OneUI
- Voice Recorder app from SE 8.0, styled to OneUI
- Device Care app from SE 8.0, styled to OneUI
- Tweaked for better performance than its predecessors (Prime, Gracified Hybrid, Miix)
- With LKT included
- Layers RRO support. Themes!
- microG and FOSS-only support
- System-wide icon packs support
- Dynamic Status Bar
- Blue Light Filter
- Hiding icons in status bar

1. Reboot to TWRP.

2. Flash Ultima ZIP first.

3. After installing, flash desired Plugins as well.

4. Reboot and continue to the setup.

5. Enjoy Ultima!
