How to downgrade from 10 to 9? :/ - Samsung Galaxy Tab S5e Questions & Answers

Hi, first I promise I'm not crazy, I just don't like some changes 10 has made regarding the operations of some of my favorite, have-to-have apps as well as how some apps interact with other apps. Second, I do apologize if this is posted elsewhere. I tried searching in several areas for this tab and couldn't find anything about downgrading.
So, here are some specs I think are usually asked for :fingers-crossed::
Samsung Galaxy Tab S5e (2019) - SM-T720NZDLXAR (USA version) (Not rooted because I'm too scared I'll kill the darned thing beyond resurrection.)
Kernel version:
4.9.186-18864194
#2 Fri Jul 17 17:31:12 2020
Build number:
QP1A.190711.020.T720XXU1BTG3
Service provider SW ver.
SAOMC_SM_T720_OXM_XAR_QQ_0001
R52MA18A3SD
XAR/XAR
Please LMK if anything else is needed.
The upgrade was done a few days ago. I searched the net for stock firmware but couldn't identify for sure if any I found would work with my specific model. I readily admit to not having the knowledge to start experimenting first and begging for help after I've blown it up, or bricked it . I'll just skip to the begging. And I'm usually pretty good at following directions when they're in basic layman's terms.
TIA for any assistance and/or guidance offered and please accept my attempts at humor in the nature they're intended. :silly:

Hello, I'm thinking about downgrading my s5e to use Linux on Dex as my tablet came with Android 10 which doesn't work with it.
If you're still in need of these instructions, I can record my steps for you when I attempt the downgrade.

So is this possible? Also, are you saying tablets that originally shipped with Android 9 are now shipping with android 10 instead??? Wtf I don't want android 10!
I don't mind unlocking my bootloader as soon as I get my tablet, but I really need android 9 and not 10. Would you mind telling me how to downgrade?

Did you ever do the downgrade? You mind sharing the details of how you did it for a noob?

New to Flashing, Want to install Eclipse [Note 3]

Hello everyone.
Is there a one true guide to installing a ROM on my Note 3? I'm running a T-Mobile N-900T. It seems that after browsing the web, I've seen so many different ways to install a ROM that I'm extremely hesitant to try one on the off-chance that it is no longer supported and may brick my device. This is a non-warrantied phone (bought it on Swappa) so I only get once chance if I end up Hard Bricking it, so my fear level is at the absolute highest.
I wanted to run Eclipse Note 3 TW Rom (found here: http://forum.xda-developers.com/showthread.php?t=2620723) because it's a nice simple ROM that retains S-Pen function and removes all the bloat and stuff. However, I noticed that it says "This is based off of 4.4.2 NC2 for Verizon Wireless." Does this mean it won't work with a T-Mobile Note 3?
This is as far as I got in towards the process before I stopped due to something unexpected:
1) TowelRoot. Rooted it and confirmed with the Root app that it was indeed rooted.
2) Downloaded SuperSU. I installed the binary using the Normal mode since I didn't have CWM or TWRM at the time. It asked me to disable KNOX and it looks like it was fine. I restarted it.
This is where I stopped. After I installed it, it asked me to confirm if I want to confirm allowing Freedom and SetCPU. I did and it continuously started spamming the notification that it was allowed for 20 minutes.
I went into the SuperSU program to see what's wrong and it then told me that the Binary could NOT be found and that I may have to flash my rom back to get it back to normal. It then gave me the error that something was wrong on my phone and that I might have to install something called Samsung Kies to make it better.
I pretty much freaked out at this point and de-installed SuperSU out of fear that I might screw up my phone. Now I'm extremely fearful to do anything without seeing some sort of de facto guide on what to do next.
If it helps, here's the phone information I have. I know that different ROM flashing methods are used for various kernels.
Model: SM-N900T
Android Version: 4.4.2
Baseband: N900TUVUCNB4
Kernel: 3.4.0-660648 | [email protected] #1 | Wed Feb 12 21:31:27 KST 2014
Build Number: KOT49H.N900TUVUCNB4
SE for Android Status: Enforcing | SEPF_SM-900T_4.4.2_0005 | WED FEB 12 21:31:01 2014
Security Software Version: MDF v1.0 Release 2
I have a 128GB Samsung SDXS MicroSD. The phone recognizes 119 GB of it which I know is normal.
Any help or direction would be most appreciated. The world of Flashing has so many roads that my head is spinning and my fear is that I will turn this phone into a $500 brick because I followed the wrong guide.
Thank you.

Thanks.
I do understand that and I have the program, but I can't find any SOLID documentation. I see all these different guides out there and I'm scared that I'm going to pick the wrong one. The ages vary as well, so I don't know if they are still relevant or not.
Not only that, I don't believe that just Odin is enough. There are also prerequisites that are required before I can just up and use Odin. That'st he part that I would hope a decent guide out there would provide me.
A bit early by a few minutes but, Bump for help.
Any information or leads would be terrific.
Thank you.

[Q] Towelroot no longer works... ideas?

I'm pretty new to the Android phones. I bought a Samsung Galaxy Note 8 tablet about a year ago, and I absolutely love it -- which was the only reason why I considered an Android phone when it came time to upgrade. That might have been a mistake.
The phone I chose was a Galaxy S5 from AT&T.
For many reasons I won't go into (and that many of you probably know) Kitkat is awful. Removing SD card access removed one of the most important reasons that I bought the phone. So, I decided to root the thing.
I read a bunch of info on how to root, and, eventually downloaded and tried to use towelroot only to discover that AT&T/Google have blocked all functionality of that program. My build is, unfortunately, the latest build -- July 22 2014 (or there abouts).
Now, I'm not sure if the phone was given to me with that update -- I only got the thing on Sunday. Maybe it was, maybe not. Dunno. So I have a couple of questions.
If I were to factory reset the phone, would that roll back these "Security" OTA updates that were pushed onto the phone? I'm pretty sure there was at least one after I got the thing. I've spent a fair amount of time setting the phone up, but I'll do it again if a factory reset would allow me to root the phone and return the SD card functions.
Is there a way to push an earlier version of the ROM onto the phone. I'm guessing not, since I think I read that AT&T helpfully locked the bootloader.
Finally, does anyone know of any way to root this device if neither of the two paths I presented above will work?
Thanks for any help. If I can't restore the SD card functionality, I'll probably just return the phone. That would be a bummer because I was really excited about it.

I see that there are tutes here, and am wading through the 50+ pages of forum posts to find what I need. However, my worry is that none of this stuff will work because of the new firmware. Here is all the info that I have on my phone:
Galaxy S5 AT&T US version (SAMSUNG-SM-900A)
Android 4.4.2
kernel version 3.4.0-2178781 [email protected] #1 Tuesday July 22
Build # KOT49H.G900AUCU2ANG3
SE for Android Status
Enforcing SEPF_SAMSUNG-SM-G900A_4.4.2_0018 Tuesday July 22
Security Software version:
MDF v1.0 Release 3
VPN v1.4 Release 1
Thanks all the pertinent info, I think.
Because the update was so new, I don't think there's a way to root this anymore. People keep telling me to use ODIN and to download an earlier ROM (and I now have ODIN and an earlier ROM -- hopefully from a good source, but I have no idea if it is), but my impression is that this latest AT&T "security" update keeps you from reflashing the ROM because of the bootloader lockout.
Any further help would be appreciated.
Thanks

Hello,
As I told you, the only method working for me (because of towelroot non working) is cf auto root.
Check periodicaly here http://autoroot.chainfire.eu/ to see if your model is listed.
I had just a look and it's not listed yet.
If it is, flash by odin and look if root works.
If not, you've got to flash by odin the same rom again (keep your original file on pc), you'll loose nothing, and report this fails on chainfire to test other solution.
Good luck

Not only build number and kernel version, you need to check your Bootloader version with Phone INFO ★Samsung★ app (in the FIRMWARE INFO section).
Bootloader version is one of the important info to check when you are going to root or flashing custom rom.

Hey that looks like a great utility. Thanks! The bootloader is G900AUCU2ANG3
Does that help any? People keep telling me I need to use ODIN and flash this, that or the other thing. Those comments would probably be more helpful if I knew more about this stuff, but my reading has lead me to believe that ODIN won't work with certain version of the bootloader. Or is that wrong?

The most effective way to debloat the Verizon Samsung Galaxy S7 SM-G930V after root?

Hi, I've successfully rooted my phone!
Is there an easy, quick or thorough way to debloat our phones running Nougat?
psouza4 had this thread with directions on how to do that, but I think it was for 6.0.1 because it's not working on my phone
My phone is the Samsung SM-G930V with the baseband version G930VVRU4BQA4 and build number NRD90M.G930VVRU4BQA4 if that helps anyone.
Anything anyone can do to point me in the right direction or any tips you could give me would be greatly appreciated.

I was thinking something similar to this or this but for 7.0, not 6.0.1.
I'm not clever enough to really know what can and can't be removed safely. I usually just spend weeks removing stuff to try and strip down to an absolutely minimum stock phone and end up just breaking the operating system and having to start over.
However, in the two links hyperlinked above, two guys both immensely smarter than me were able to strip the phones of all the bloatware and then some while remaining on stock roms and having a very functional phone.
I was hoping to find something like that.
For now I'm just downgrading to a rom that came out before Sep 15, 2016 and then following the steps in this thread to get a functional rooted phone that is tweaked to run okay, then I'm using the steps in this thread to strip the phone down to almost nothing but still keeping it functional.
I would rather have total control of the applications and software on my phone and use a dated operating (6.0.1) system versus using the most up to date operating system (7.0) and not having as much control or understanding of what's on my phone.
I would love to upgrade to 7.0 though if anyone knows an extensive and reliable way to extremely debloat the Verizon Samsung S7 SM-G930V with a locked bootloader?
I've lurked and googled every variation of any combination of words to try and find the right place to learn how to do this but fell back on the two threads I hyperlinked above, twice. I can't find anything that works for me for 7.0
If anyone wants to emulate what I did to get a similar result, I used the firmware version G930UUEU4API3 for the device Samsung Galaxy S7, model SM-G930U for my SM-G930V (apparently the G930U version doesn't come with Verizon bloat? just standard bloat?) because that version was released 9/09/16 and the thread for the extreme debloat was last updated 9/15/16, probably to account for that release. After that nothing has been updated.

Help with a SM-T510

Hello,
I am pretty much a noob at this, only successfully done a one custom rom and twrp install before on a google nexus a long time ago. But pretty much after getting really confused as what I can do with it.
I just bought this tablet about a week ago from a Best Buy. Its a 2019 model without the sim-card port, so it is wifi only.
The model number is sm-t510nzkaxac. Its an ok model, but there are a few things I am not happy with about it and I was wondering if anything could be done to fix it.
It doesn't have Android 10. Only 9. And having a little bit of knowledge about software and what not I have to wonder if some of the issue I am facing are related to this. Some of the apps are not usable and others there is no sound or other issues that do not occur on other devices with different android versions. Crashes and app hangs frequently.
Android 10 seems to work best(with another samsung tablet [sm-t307u]), naturally, so I wanted to see if its possible to update to this firmware somehow.
Please explain everything, as I said I am a noob.
Thank you.
I should also mention that I use Linux. Debian 9. If this is an issue...

I'm assuming it was a typo and you are actually talking about an SM-T510 and not T501. If that is the case, Samsung has yet to update the T510 to Android 10. There are custom Android 10 ROMs but not stock. So if any of the apps that came with the tablet aren't working, then there must be a defect. If you have installed additional apps, designed for Android 10, then they might have problems. But anything designed for Android 8 or 9 should work.
Yes thank you, it is the T510, just a typo.
I understand that Samsung has yet to update this device to android 10, which is kind of disappointing. But issues I am facing with some apps are with this model with currently has android 9. As I said before the newer device, and SM-T307u (2020) does have android 10. Also I've heard that Knox Security could pose a problem.
Basically I wanted to test to see if this is the issue with the T510. I've gotten as far as unlocking the boot loader, but beyond here I am confused. Probably because I am a linux user trying to figure out a way to do this without a windows computer for the odin software. What I have found so far, heimdall, doesnt work at all. I am guessing if I cannot get TWRP or any other roms on the tablet, I cannot get this to work?
I hate being a linux user for this reason, lol. Everything is made for windoze!
And yes the apps in question are ones added after market.
Anyways thanks for the response, cheers!

My T720 just got 10 also. But that is to be expected. The more expensive models always get the updates first. It has been known for months that the T510 wouldn't get 10 until Sept. I've been a Linux user for 20 yrs but I keep a cheap Windows box just for situations like this. However, there have been others who have used Heimdall to install custom ROMs on the T510. Do a search in the threads for T510 custom ROMs for Heimdall and see what others have done.:fingers-crossed:

Well I guess I need to find a cheap windoze computer someplace... Lucky I can usually find one at the recycle depot for nothing. Probably a good idea, though, Lol thanks. As for android 10, I might just wait until Sept. for the official update, dunno yet. Depends on what happens I guess.

The only problem with waiting till sept is that that was the schedual prior to covid. Can't be sure they'll hold to it.
Yes, covid... well lets hope that most of the development can be done at home and samsung employee are not actually working at the office I guess.
