Unable to Flash TWRP or anything else - Samsung Galaxy Tab S4 Questions & Answers

Hi there,
first of all, sorry for my bad english.
I want to remove the Stock ROM from my Tablet (Samsung Galaxy Tab S4 | SM-T830) and install something else (https://www.getdroidtips.com/android-12samsung-galaxy-tab-s4/).
For some Reason Samsung forced me to do a factory reset to unlock the bootloader (maybe I did it wrong, but now it happened, so it is how it is). Now the OEM Unlock Options says "Bootloader is already unlocked", but when I go into Download mode, I have multiple Problems:
1.: When I enter download mode by Booting into Recovery (adb reboot recovery) and choose "reboot to bootloader", OR by entering it directly using "adb reboot bootloader", I dont get the Warning Screen so I get into download mode directly.
2.: When entering Dowload mode as descibed in problem 1, I also dont get the informations at the Top left, I only see the Download Icon on a blue background but when restarting the tablet and holding Volume Up and Volume Down simuntainuasly, it will show the warning (in the correct cyan colors) and in the next step it shows me those status informations at the top left.
3.: However, regardless to how I get into download mode, the colors of the download mode screen will change to a blue filter version after one second. but I did never activate any blue filter on the device, and on any other device, the colors are displayed correctly.
4.: Any instalation with Odin3 failed on the device, regardless to how i got into download mode
In any online article I read, noone has any problems with installing something when in download mode.
Also, the KG-Status is displayed as "checking, I dont know if this is good or not.
What am I doing wrong, why can't I install anything on the device?

what is wrong with download mode? post a picture.
drivers installed correctly? check in windows device manager.
what does not work with Odin? what error message?

First of all, thank you for your reply!
1.: The Picture shows that the is something wrong with the Download mode of the Tab S4, because the Colors are not being displayed correctly (as you can see, the colors of the other devices are much more cyan), and I would not have mentioned that if the device would just be unable to show colors correctly, but in the Warning before the Download mode, the Colors are displayed as they are on the other devices, so the eventually the device wants to tell me something, but I dont know what.
2.: Well, I am pretty sure that the drivers are installed Correctly, because Flashing a Galaxy Tab S2, Galaxy S8 and Galaxy S5 worked perfectly with the same driver.
3.: I'l attach a Screenshot of Odin.
ALso, what does "KG STatus: Checking" mean? Is it the reason for the problem, or is it good? On the Web I could only find "Kg Status: Locked" and "KG Status: Unlocked". should I unlock it? If yes, how?

you say any installation with Odin3 failed. you are trying to flash TWRP.
try to flash something different.
https://topjohnwu.github.io/Magisk/install.html#instructions
not sure about the display, though.

Well, I have a porblem with the Program that is mentioned in the Guide you linked, Frija asks for a CSC, and I dont know what I have to enter there, I only know that the device is a SM-T830/gts4lwifi.

CSC is region code
Rooting, ODIN, Firmware, CSC Information And Myths Debunked / Noob's Guide To Samsung Devices
Since a lot of people will have their Galaxy S22 Ultra soon and I myself am thinking about either getting an S21 Ultra or S22 Ultra, I wanted to summarise a lot of information I found out during researching as Samsung devices are quite different...
forum.xda-developers.com

Okay, maybe I am an Idiot or so, but it does not work, Frija does not find any Firmware for the SM-T830, flashing a custom build of TWRP also does not work, folowing other Guides to install Magisk doesn't work, and using Odin to Flash a System Imagge (in the Guide I saw this was how they did it) also does not work.
Also "adb sideload" does not work using the Stock Recovery, so I really need TWRP to do so.
When searching for the KG Status, I found out that Samsung devices are checking themselves for a Week or so before accepting any Unofficial images, since I factory reseted the Tablet two days ago, the device may check itself. So should I eventually wait a Week before trying it again?
I dont know what I could do, so that seems logical for me, do you think that might solve the Problem?

Well, if RMM/KG state is prenormal you would see message "Only official released binaries are allowed to be flashed"
Anyway, try to flash official ROM and wait for KG state while device is connected to internet.
you can download according to your region from https://samfw.com/firmware/SM-T830

[Q] Odin bricked. Can get to DL but Kies won't identify my phone?

I am something of a long time XDA user, having been flashing since the time of the HTC Wizard. But I had never bothered rooting my S3 until I decided I need to install music on the SD card using doubletwist.​
I installed the toolkit and the drivers properly but SuperSU 2.48 doesn't download (yes, I paid a donation), -error messages such as 'couldn't resolve host skipsoft.net' or 'HTTP doesn't seem to support byte ranges'
Option 1 loads what seemed to be an old (2.42?) version of the Odin flash tool: if I follow the instructions, the S3 does to into Download mode (with a message 'do not turn off target) and after about five minutes Odin shows FAIL on the TWRP recovery operation it seems to be executing. It then tells me to be patient while (I assume) rebooting but after about 30 minutes of waiting, the phone doesn't come out of download mode.​
I then rebooted and tried to flash again and again, the flash failed completely, and the phone seems bricked, giving the error message 'firmware upgrade failed, use KIES recovery.
It does go into download mode but when connecting to (newly updated) KIES, the model isn't detected in the recovery procedure so it won't either recover itself or give me a code to do the KIES emergency recovery.
Currently showing in DL is:
ODIN MODE
custom binary downloads YES (1 counts)
curent binary: Custom
system status: Official
qualcomm secureboot:enable
warranty bit:0
bootloader AP SWREV:1​
What is a recovery procedure please? KIES? Some other flasher? Some newer version of Odin?
Oh, and when I plug the phone into the computer, it suddenly recognizes it as an MSM8960, whatever that is?? Before the computer recognised it as the more normal SGT999. Also (this is obvious), the device is no longer recognized in Explorer once the device is connected if you connect it in DL.
Is an MSM8960 the same as a SGT999 in DL mode?
Sorry no one posted any tips or tricks on this request! In default, I ploughed ahead with the normal instructions, remembering that often when flashing doesn't work for no apparent reason, trying again does get everything to work
Re-flashed stock with Odin from download mode, which worked fine and unbricked phone. Then tried TWRP again, which worked fine as well, always providing instructions are followed.
Eventually found myself back at what looked like stock, but with message that I haven't rooted but would i like to do so now using the SuperSU that the toolkit said it was using? If so, down load it from the Playstore, which I didn't understand at all. I thought the playstore was against things like rooting?
Anyway, everything ran to completion, though I am still working on how to use DoubleTwist to transfer albums to the SD card on the Galaxy. (error message, apparently from SGS3 Easy UMS: 'You Do Not Appear to Have Busybox Installed', followed by loop of preparing SD card for mounting, mounting Then nothing by way of D card shows up in DoubleTwist)
Don't use toolkits, they are not updated and have caused many issues. To root, use towelroot

is there a list anywhere of devices which work with towelrroot please or is it only flavours of s3? i have a curious MK 6571 S6 which seems to defy identification because it isn't an iPhone knockoff and it is having the hardest of times addressing its hard drive. Whatever i try to install on it results in the error message that there isn't enough hard drive space to install. Towelroot also gives this error message which i believe to be entirely spurious, and it is a really tiny!! something appears to be preventing it installing any app on it which can read or influence any hardware on it?
(I also tried installing framarooot 193 but it gave me the same out of space error message)

So it is an S6 knockoff? I'm not sure if there is a list but the s6 definitely is not compatible

hey friend, your woes sound alarmingly familiar to my own not so long ago. I will start this post by saying I am not going to come out and declare myself as anything but what I am, an average guy with an interest and at one time identical dilemma as yourself.
that being said what exactly are you trying to achieve an are you willing to start from scratch? are you backed up? these are my questions. in answering or perhaps confirming what you may know is that once rooted and subsequently bricked kies ceases to be a friend to your device and it is with odin that your phones future if is to have one lies. I personally have enjoyed much success with the program but at this point ive only done a handful of operations with it.
If what ive written has given you any encouragement please feel free to respond and I'll gladly explain what i did to restore my s3 because i wouldnt want to advise outside of something I have tried myself and know to be safe and conclude with a desirable result for you

Custom binary blocked by FRP.

My friend's J2 Prime (SM-G532G/DS) happened to be stucked at Security Error (blue screen), no idea how it get there. Tried to flash stock firmware. But after flashing, the phone booted back into the same blue screen, now with a line of red text at the top saying, "Custom binary blocked by FRP. (recovery. img)". Tried many different stock firmware (with 4 files) but none of them solved the problem. Can't boot into recovery, only download mode. Can someone give me detailed step by step on how to fixed this.
If it help, I'm from Malaysia. So maybe the firmware might need to be from this region. Not sure about the origin of the phone though. Also, what could be the reason for this to happen? I'm assuming root. Could it even happen on its own, I mean without rooting or flashing?
also G532G/DS - ARH1 bootloader
i've been going thru lots of ROMs (including testing Lineages), this have never happened to me before.
Flashing stock firmware thru Odin though, require OEM Unlocking ON in Developer Settings.
^ I mean, did you/your friend turn it on before flashing? if not, it actually succeeded?
Only solution might be possible:
Go to stock recovery (POWER + HOME + VOL-UP), wait for it to load, then factory reset from there.
I suppose some images might help!
I'm pretty sure the OEM if off because he know nothing about this thing. When I got it, it already like this. Can't get into recovery, after the first Samsung logo appear, it went straight into the error screen. Same thing happened after flashing.
I don't know how to post images here...

+ OEM Unlock: if disabled, Odin should've failed straight away and no reboot stuff going.
+ Can't get into recovery:
Is it true that you cannot get into recovery? If left stock, It should be an Android with spinning stuff, text is "installing update" then no command for a while ~2min, and it will go to normal recovery.
I mean, it is supposed to do "recovery" :v
+ Images: post it on Imgur (or any online image service). Copy link here, add space between "https://" and all the stuff there. Wont be considered URL i guess (havent tried)

[Samsung] Galaxy Tab 3 SM-T210 / "Firmware upgrade encountered an issue"

Hello!
Few days ago i found my Samsung Tab 3, and decided to charge it and biit it up.
It got stuck on Samsung logo when i booted it.
So i did a factory reset using the recovery mode.
After i did that the device booted up. with lots of errors.
I was on the setup screen for my device and these errors appeard and said like core has stopped working and every like preinstalled app on my samsung device aswell (NAME has stopped working). So i was not able to fullfill the setup of my device.
I read about it online and a firmware upgrade could fix the problem ( Like the easiest way i read )
So i did some googling and downloaded Odin and a firmware. Followed a guide and did everything right. BUT the process faild like 8min into the flash.
And now my device is stuck on "download mode" but with the error "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
I cant get the phone to turn off, nor get into recovery mode or anything else. I tried flash again but no luck.
I also tried another firmware i found. still same problem.
How do i fix this and how can i use my samsung tab 3 again.
WHen i bought it years ago i never really used it. So it's in "new shape" and has never really been used. And now i wanna give it to my little sister for some kids games to play at Xmas.
I hope we can solve this problem.
Thanks in advance

That depends on various things, such as the Android version, kernel and change ID. Than also the Odin version you've used and/or the settings during the attempt of flashing. I found that using the wrong Odin version on a particular Android version, that may prevent the flash of being successfull. B.t.w, did you format both user and cache partition while trying to reset to factory default?

Yeah, I've found out what Odin version to use that worked for others. I've downloaded lots of different firmwares and such and tried. ALL fails.
When i did a factory reset i also cleared cash and user.
Now i cant even turn off the damn thing. If i charge it up and start, it just goes directly to the screen where it says "Firmware upgrade encountered an issue" and if i try to turn it off, it just reboots and goes back. And i cant even return to factory reset page.
I think that my Micro-USB cable might not work for this, or is that a thing? Do i need a good cable from PC to Phone for this? Or does any cable work?
I just want this tab to work. been trying for weeks.
Thanks for your reply. I hope we can sort this out.

It is quite easy to turn the device off, for that to happen you have to press and hold the on/off button. You'll see that the device will shutdown and try to reboot and then finally shuts down again and stay off, then release the on/off button.
Are you sure trying to flash the correct firmware with correct changes, etc??
Please share with us the device and Android version, as well as the stock ROM version with changes you're trying to flash.
Put (copy and paste) the output of Odin below.
Another way to get the firmware flashed is by using Heimdall, but for that to happen you first need to rename the extension of the stock ROM (remove .md5 and leave .tar) and than extract all seperate pieces that are contained within the stock ROM.
All those extracted pieces from the stock ROM you have to upload seperately onto Heimdall and try to flash them to your tablet, one by one.
Heimdall you'll find 'here' or use FWUL instead which has Heimdall pre installed, download is to be found 'here' and install it on a USB medium a stick, to put FWUL onto USB, use Balena-Etcher and the download is to be found 'here'.
Micro USB cable does work, but if you're unsure, try another one and make sure using the correct drivers too.
Using Odin, make sure the tablet is recognised and 'connected' in Odin, also make sure 'repartitioning' is unchecked.
If you've used the wrong Odin version, flashing will fail!

Hi, complete novice here, does anyone know where I can get a working Firmware for my Tab 3 v7 (SM-210)?
I have searched through various forum articles here, and tried to install with several builds but none will install. The only one that gets anywhere near is the JASBR build by gr8nole. It appears to install, but on restart, the TAB just sits on the "Samsung Tab3" start screen.
I read that I may need to flash the firmware 4.4.4 (Kit Kat), but can't find it!
The unit is not totally bricked (yet), as I can run TWRP 2.8, with which I created a backup of the original build, but when I try to restore the backup, it fails at just over 31%.
Can anyone help please?

Samsung j610fn stuck in bootloop even after nand erase and pit flash, please help !

Greetings,
I have a certain problem, i have an Samsung J6 Plus which has suddenly rebooted and since then it just turns on the samsung logo, then it turns off the screen, then the screen flashes and finally it reboots again.
I have tried everything, the phone has a pie binary so i could only flash one rom i found.
But even after flashing every part of OS on its own, performing a NAND Erase and re-partitioning with pit file, i still get the same result. The phone restarts after the flash, and then turns off the screen, flashes etc...
Every time the same, no matter what i try.
Has anyone experienced similar problem ?
I have read about 15 of other threads here with similar problems and tried every solution that works for some people but nothing works for me.

You shouldn't have used the nand erase option, that is an easy way to brick the device when used improperly. I doubt you will be able to repair it with Odin now.

But, you see, i did it as a last option, because i tried to flash several different roms before that, and at first it didn’t let me flash Oreo and older, just failed in odin, because of Pie binary.
So i flashed official pie ( first time only AP, and second time all files), and it didn’t help either, the phone was still acting the same (the same thinh happens like before all the flashing).
I can’t boot into recovery, it ends up being the same as trying to boot normally, and it won’t let me flash other recovery because of the frp.

Sounds to me like the hardware itself is bricked or damaged. If that is the case, the only option is to replace the motherboard.

I'm having the same issue after oreo update for j7 nxt so what i did is easily rooting phone via Magisk!
Ahh,, maybe u have frp lock?
Just google for (Combination rom of your device) then flash it with odin. After that you can go to settings -> about device -> software information -> Build number (click on this option 5-7 times).
Then back to settings you'll see an additiona setting (Developer options) go inside it and click on (OEM unlocking) and cograts you have unlocked frp lock
Note : there is a fairly chance that you won't find this option (OEM unlocking)! So what to do? You just need to trick the phone by changing the date/time for 2014 and restart then check if it's there if still not there just try again with different dates for ex. 2013 and restart (keep doind this and every restart check the developer options section, Just KEEP TRY!! until you find the button there in developer options
After that go flash the stock rom then install TWRP then ROOT via Magisk and you're all done

OEM unlock does not "by itself" remove FRP, there is more to the process than just enabling OEM unlock, removing the Google account from the device and disabling MDM(find my device) is what actually "unlocks" FRP.

Since he didn't mention about getting this message "only official binaries are allowed to be flashed"
Then itsn't something related to RMM.
Also as what he said he can't flash TWRP as he gets "OEM LOCK" it's also called "FRP LOCK" the type of lock i'm talking about is in (download mode) that doesn't allow to install custom binaries, so the only solution is tirning (OEM lock) option and that's enough to flash custom binaries such as TWRP.
The type you are talking about seems to be RMM lock which could be fixed using Miracle Box but as it's not allowed to dicuss this stuff here in xda + his problem is frp locked and phone doesn't booting, so the only solution we can provide in this situation is Combination rom which will boot even if you bricked your phone, even if you've Rooted and bricked your device's kernel (even if it won't boot anymore).. combination should boot, i faced the exact issue but as i explained in my last post. And hmm it could be 80% the solution.
Thank for your reply.
Your Iraqi friend,
My regards.

Also as what he said he can't flash TWRP as he gets "OEM LOCK" it's also called "FRP LOCK" the type of lock i'm talking about is in (download mode) that doesn't allow to install custom binaries, so the only solution is tirning (OEM lock) option and that's enough to flash custom binaries such as TWRP.
The type you are talking about seems to be RMM lock which could be fixed using Miracle Box but as it's not allowed to dicuss this stuff here in xda + his problem is frp locked and phone doesn't booting, so the only solution we can provide in this situation is Combination rom which will boot even if you bricked your phone, even if you've Rooted and bricked your device's kernel (even if it won't boot anymore).. combination should boot, i faced the exact issue but as i explained in my last post. And hmm it could be 80% the solution.
Thank for your reply.
Your Iraqi friend,
My regards.

No, I'm talking specifically of FRP lock.
The point you make about binaries has nothing to do with FRP. Binaries can be blocked on both FRP locked and FRP unlocked devices. The binaries only prevent flashing firmware with a lower binary than the current binary installed on the device. Binary version is related to RMM or KG state, not FRP. FRP is directly related to MDM and only "partially" related to the things you mention and only because there are other "tamper-proof" elements that "can" trigger FRP. Have you ever noticed that a device that does not have a Google account signed in does not encounter FRP issues when the device is factory reset, but if there is a Google account signed in the device, factory reset triggers FRP? If it were as you you seem to be suggesting, FRP would be triggered on devices that have no Google account associated to them when attempting to flash/modify the device, but this is not what happens.
OEM unlock really only applies to unlocking bootloader in order to flash unapproved software or make modifications to the system partition without being blocked.

Help Needed - Bricked

Before I get going - yes I know I messed up. I do have plenty of experience flashing ROMs etc, albeit I'm absolutely not an expert. This was purely a not thinking moment.
So I flashed my Samsung Tab S4 with Kali Nethunter a while back, not really used the tab since. Without a great deal of thought, I decided to put the device back to factory. I went back into the OS and flicked the OEM toggle - utter braindead move. Obviously the device now comes up with a warning, the exact wording is:
"Security Error: This device has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair / return for this issue may have additional cost"
I can still access download mode.
Right, now you've finished laughing/cussing me I did some digging and apparently I can still flash with Odin if its the official ROM? I went to SAMMobile and downloaded the latest ROM and Odin fails with a write error.
What I need to know is:
How bad have I messed up?
Is this recoverable?
Any help appreciated.
Hello there,
So yes, pretty bad mistake but these things happen but it should be recoverable. Just follow the link to get your device booted up! Hopefully the link is for your variant, if not look into installing twrp recovery for your device. Once installed you can back up your data and flash the rom compatible using twrp. Then set up the device and restore your data but make sure it's unlocked or your error may repeat itself! Also you have to find the right version of Odin, they do vary some are patched. Have fun!!
Recovery
Hi,
Thanks for the reply Jedi.
It already has TWRP on it, but recovery is inaccessible since I turned the OEM lock back on. The only thing I can now access is download mode but it can't seem to write to it, which I'm guessing is because the OEM lock is back on. I thought I might still be able to write the official Samsung ROMs even with the OEM lock but it doesnt seem like its the case. Obviously no access to ADB to do a Fastboot unlock either. Fresh out of ideas.
Any other solutions?
bump - anyone? lol, really not looking for an expensive door stop.
It seems you're at the dead end. However, there might be a solution for this, not sure though does it work. But go to OnePlus forum and you'll find how to recover from bricked device. You still got hope because of TWRP. good luck bro
OK, so for anyone wondering if this is fixable, the answer is YES!
You can flash the standard ROM even with the bootloader locked. Clearly what I downloaded from SAMMobile wasnt compatible, however when I used Frija, it found and downloaded the correct ROMs.
Another sticking point of this was the infamous USB 2.0 issue, I assumed the ROM was failing again, however when I finally could be arsed to try it on my old PC, its worked like a charm.
So there you have it:
Latest version of Odin
Latest Samsung USB drivers
Latest ROM downloaded from Frija
Put the tablet into download mode and flash away.
