Samsung Galagy Tab S4 stuck after rooting ? what i did wrong ? - Samsung Galaxy Tab S4 Questions & Answers

Hello !
i think i messed up a little with my T830 and now it's kinda stuck on the bootscreen.
i wanted to root it so , i followed an online tutorial but it looks like i did something wrong.
here is the steps i followed :
i installed The Samsung USB drivers
i installed Odin
i sat my tablet in the " OEM Unlock " and forced the download mode in order to install the patched boot.tar in the AP mode in odin 3. the Flash was sucessfull.
once it was done, i installed the " twrp-3.6.2_9-0-gts4lwifi.img.tar " via Odin in AP mode for my tablet, in order to have access to the twrp menu but it don't work.
( the flash was sucessfull )
Now my tablett is stuck on this screen and the only thing i can do is to reboot it.
i can't boot it in download mode anymore.
i guess the last file i flashed was corupted or innapropriate ? but i don't really understand what i did wrong. my tablett is the SM-T830, so it should work fine ?
i'm kind of worry because Odin and adb don't see my tablett anymore and i don't have access to the Download mode anymore.
[Update: sometimes i manage to have Access to the Download mode ( but it's really tricky ) and i can see my tablett on Odin 3, my tablett still can't boot on Android. I don't know what file i need to flash in order to fix my problem ! Help :I ]
[ Update2: i managed to download the stock rom via Frija, and installed it, but my tablet is not rooted anymore, it's still better than nothing i guess ]

Help Please. I can only go to Download mode

Hi guys,
Looks like my phone's in deep sh*t right now. Here's the story.
I'm coming from Criskelo rom JB 4.1.2
I wanted to try another rom and found this [ROM][4.3][NA1][9/2/14]►Xperia-Z-ized™ and i thought, this looks cool and wanted to try it out.
Managed to install the ROM perfectly, Phone works and everything but then the Wifi isn't working so i did what was told, to use the bootloader patch by Dr.Ketan. This was in the FAQ's 2-3 post below the Rom screenshots.
Extracted the file, put my phone in Download mode and connected in Odin. according to Ketan, use the PDA tab so i used that to locate the bootloader patch. started Odin, i think i was waiting for a good 5 minutes but the process still hasn't completed. still waited for 10-15 minutes more to find out that my pc is actually frozen. so i disconnected my device and restarted my pc.
F*ck now my phone is showing this. Please Help, what should i do? It's not going to Philz recovery mode but i can go to Download mode (Vol down + Home + Power). I'm definitely not downloading Kies as i know it disrupts Odin in someway.

Tab 3 GT-P5210 Failed Root

Hi, I tried to use Odin to root my Galaxy Tab 3 GT-P5210 (Build KOT49H.P5210UEU0CNK1), and it said "Passed" on Odin, but my tablet is now stuck on the "Samsung Galaxy Tab 3" startup screen (it won't boot). Is there a way to remedy this? Also, I can't seem to download any TWRP files, it gets blocked by the antivirus saying that a virus has been detected in the file. The only other option I can access is when I press Volume Down and Power at the same time, it goes into ODIN Mode on my tablet.
Thanks
Try to flash bootloader (BL) with Odin, CSC is not needed but it doesn't hurt to flash it with BL.
In this file, CSC (Country/Carrier Specific Code) is for US region
http://www.mediafire.com/file/c224oin6adfqisg/GT-P5210(2).rar
If it doesn't work, try to flask BL, and AP with Odin.
The stock ROM ( AP ) is here, and Cellular South is for US region
https://www.sammobile.com/firmwares/database/GT-P5210/
I rarely fail when flash Stock Rom with its bootloader ( BL )

Hi
Is it still possible to root my Tab 3 P5210? And then flash a custom rom of android 6 upwards?
It currently runs on android 4.4.2 but im not sure if that was the version it was purchased with originally. I tried recently when i followed instructions from another thread on here but i soft bricked my device (same as OP - passed on odin, tab stuck on loading screen), although i did recover it back to its previous state eventually. I was using the latest Odin V13, but im not sure if the version of android or odin version needed to be specified for using the right apk files?

Doubts how to root Samsung A50 sm-a505fn

I want to root sm-a505fn, I already rooted some phone so I am familiar with TWRP and Odin.
First thing, why isn't the A50 listed on the TWRP page? there are only Samsung Galaxy A5 2016 (Exynos) (a5xelte) and Samsung Galaxy A5 2017 (a5y17lte).
I have read about the OEM unlock, however didn't understand if I have to disable (grayed out) it or not, since some tutorial say different things.
At the end I tried with this fw, but it doesn't work. W or w/o OEM Lock, I get blocked by oem lock . Odin does not complete, it is stuck on VBMETA RQT_CLOSE !!.
Maybe because of the locked bootloader? I was wandering why in each tutorial I find press volume up to unlock the bootloader but when I restart the phone in recovery mode, I don't find that screen, but the following one. After I select Reboot to bootloader I get in download mode:
{
"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Other tutorials say to power the phone with VOL UP + VOL DOWN, but does not power on at all...
Phone Info:
One UI VersionOneUI2.0Android Version10Product codeITVPDAA505FNXXU5BTL3CSCA505FNOXM5BTL1
Need explain please.
Thx
At the end I have been able to unlock the bootloader and install the TWRP from this guide, but:
- no-verity-opt-encrypt-6.1 fails to install
- multidisabler-samsung-2.2 gets installed but don't know how to check it...
- Magisk-21.2(21200).zip gets installed from TWRP but does not result to be installed on the phone
- MagiskManager-v8.0.4 from phone get installed, but even if the installed version results to be last available, it proposes to install it. Furthermore i do not have the option to direct install Magisk (the third option)...
Could the problem be the wrong version of TWRP?

Galaxy Tab S4 stuck at boot after trying to root

Hello together
I tried to root my Samsung Galaxy Tab S4 according to https://appuals.com/how-to-root-the-samsung-galaxy-tab-s4/
There I came up to step 10 (so I flashed the two files). Now the Tablet is kind of stuck in the boot screen showing this (the same for step 8 and 10 but at step 10 i lost the ability to get to the download mode):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The only thing possible is to gamble a bit with the keys power, volume up and down to get the yellow sign in the top left showing "kernel" instead of "recovery". Otherwise if I press all three buttons together the following screen comes:
I am a complete noob in that kind of things and got no idea what to do now. There is no possibility to open the download mode to revert something, neither TWRP is shown as it should according to the Description in Link above. If possible I dont want to get anything deleted. What can I do?
EDIT: If possible I still want to root the tablet because I only see advantages in it, even I never found a good (explanatory) tutorial on it.
kind regards

Ok as I was very impatient and tried a bit, the blue screen is actually the "ODIN Download Mode". I reinstalled the stock firmware (loosing all data) (and rooted the device with Magisk later on) so the sm-t830 works perfectly again.
