T230nu Won't Boot, Bricked, Looking For Help - Galaxy Tab 4 Q&A, Help & Troubleshooting

Hey everyone long time lurker here and I need some help.
I came in to possession of a T230nu that won't boot. When booting into recovery it boots to TeamWin so it looks like someone botched a root or something. When attempting to recover with a stock rom in odin it always fails. Binary and system status both say custom.
Any help would be appreciated.

[Q] Help on my SM-N9005 boot loop

Hi to all fellow XDA-ers,
I'm a newbie on Samsung devices and I flashed a custom rom without knowing the consequences. Thus, my wifi was not working. Then I decided to restore my nandroid backup to the rooted version only that I have backed up before flashing the custom rom. Then, I got this boot loop issue. I'm tried downloading the un-modded firmware for XXUBMI7 on the Samsung Updates site and going to download mode and flashing it through Odin, but the boot loop issue is still there. I'd really appreciate someone/everyone who would help me on this. Thanks in Advance! :fingers-crossed:

Newbie, stuck on Boot Screen w/custom logo

Not a proud moment here... I have been running a rooted SM-N900V for a while on 4.4.2. Wednesday I made a backup of the rooted 4.4.2 using safestrap to the external SD card. I then wiped the ROM and tried loading JasmineROM 6.1. After flashing, the phone rebooted to the Verizon unauthorized software screen. At that point I could not boot into recovery. Using ODIN, I was able to load flashN900VVRUEOF1_PartialFirmware.tar.md5.7z which allowed me to boot into recovery. However, for three days, I have been stuck there and cannot get any further. I have tried flashing stock ROMs in Odin but all I get is the AUTH fail and Write fail. Is there a way out or is the phone toast? Is there a way to load the recovery I made in safestrap?
Any help is greatly appreciated even if I have to mail the phone out...
Thanks!

Rooting Samsung Galaxy J1

Hello, I would like to ask for advice rooting this phone (J100H). I've already tried this http://forum.xda-developers.com/android/development/rom-gennxt-prerooted-stock-t3126368, but got stuck in the boot loop and flashed a stock rom back. Would flashing the TWRP recovery help? Or do I need to flash a new bootloader? Doing the "oem unlock"? Thanks for any help.

Stuck on logo bootloop with no ability to flash TWRP nor downgrading

Hello guys,
here I am on the Galaxy S8 bootloop caused by flashing following firmware using Odin 3.14:
G950FXXSBDUA3 FIRMWARE.
After that I got bootloop on Samsung Galaxy S8 logo. I can't downgrade to previous version, as Samsung blocks that and I can't flash TWRP neither (when trying to do so I get "Only official released binaries are allowed to be flashed (RECOVERY)" ; I've forgotten to tick "OEM Unlocking").
So now I'm stuck at the moment where I don't really know what to do. Have I bricked it completely or is there any way to recover?
Thanks in advance for answering.
Cheers.
UPDATE: I just solved the problem. The solution was to flash the stock ROM again, but this time with the .pit file and tick the Nand erase and Re-Partition. After that it booted normally. Hope this will help some fellows with similar problem.

Samsung Galaxy S5 Active sm-g870a Help

Hello!
I apologize if this isn't the right place to ask, but I haven't found a section for a Samsung Galaxy S5 Active!
I am a complete newbie and haven't flashed to my phone since I had a Samsung Galaxy S3 back in 2018. In this case, I'm trying to find a root and install twrp recovery, so I can install lineageOS on my phone. The stock rom is so laggy!
My phone's recovery won't let me just install lineageOS, so I have to install a custom recovery.
So far, all the one-click roots haven't worked. Towelroot, kingsroot, oneclickroot, all failed.
The official twrp recovery didn't work either and did not give me a compatible rom.
I tried to locate an unofficial twrp recovery compatible with my device, and I think I found one. The issue is that it odin does not flash a .img file.
I'm going to try this method of downgrading the stock rom.
EDIT: Doing this gives me a SW REV CHECK FAIL: [aboot] Fused 2 > Binary 1
Trying this now: https://forum.xda-developers.com/t/guide-g870a-downgrade-s5-active-mm6-0-lp5-0.3523683/
EDIT: unsuccessful. Soft brick of OS; need to flash again or try something else...I tried to leave the phone out all night, but it never got past boot screen.
EDIT2: tired again and somewhat successful. Samsung boot screen is different and so is the boot recovery! The darn phone still won't boot though!!
EDIT3: Had to reboot the phone 3 times and got the android is upgrading screen...YAY!! But, the system process.media fails randomly.
Any tips? If I could just get twrp on, that would fix everything! Thank you!!
Found a supposedly compatible twrp here: https://dl.twrp.me/klte/twrp-3.5.2_9-0-klte.img.tar.html
Issue is odin fails when flashing...I am getting the auth error!!
One of the few usable recoveries: https://forum.xda-developers.com/t/...estrap-recovery-v3-75-2014-06-26-b03.2794087/
Hi, I am also looking to put LineageOS on my device as well.
The most I have found so far is the S5 Active (SM-G870A) has an OEM locked bootloader, and without unlocking it a custom recovery is not available.
AT&T, nor Samsung have provided any way to unlock the bootloader as far as I know, and I'm not sure if any developers are still working to crack it.
