I tried to root my g9650 s9+, I finished everything with TWRP recovery and now everytime the phone tries to boot it just gives me the Security Error this device has been locked because of unauthorized software. I cant access recovery mode. I am planning on flashing the stock rom with Odin, is this the right thing to do? Please help.

Solved it by flashing stock fw, do I have to wait a week again to attempt root again?

Hello, today I started to having some more fun with my LG G5, I unlocked bootloader, flashed TWRP and installed SuperSU, then I started to flash firmwares. I flashed "Tizen" rom for G5, flashed nicely, everything was working and I had one more software to flash on my sd "Genisys" which I wanted to try. After flashing I was stuck on lg logo, went again to recovery, and formatted system, then again flashed this soft and after rebooting I was stuck in a recovery loop.
From here: https://forum.xda-developers.com/lg-g5/help/bootloop-twrp-t3514927 I tried the solution and my phone is showing now red triangle with "Your device is corrupt. It cannot be trusted and will not boot.
I can still get to bootloader but when i try to flash my unlock.bin again there is a "Bootloader Unlock key write fail" message.
Any help appreciated
Solved: Download mode worked so I installed V20a KDZ with LGUP.

Did you try to unlock the bootloader again - after you unbricked it?
If so, did it work?
@bobiak
Congratulation to your result! Most of the guys i know, would have a unusable paperweight after those experiments.

When trying to solve the recovery loop (the link attached) you are moving some system files where bootloader is, so after flashing with KDZ I had bootloader locked againg, but when I got in that recovery loop again and didn't mess with moving any system files, after flashing KDZ my bootloader was still unlocked.
I didn't flash my unlock.bin to see if really bootloader is unlocked, recovery and root flashed without problem.
same problem

I really don't know what is left to do, I always end up with a bootloop and have to repair my phone with flashtool. I have tried flashing twrp by adb/fastboot, temporarily booting to twrp, flashing different twrp files after repair.... I always get boot loop. Help please :/
Once I had my phone rooted by oneclickroot support, then I started to get play store crashed constantly. Once I booted to recovery and when try to reboot, got a bootloop. I tried to flash a new rom, so found a stock rom for Z5C and flashed it by twrp. But after a reboot I lost the twrp recovery this time. Then I tried to flash the recovery myself using abd, following the basics; fastboot flash boot boot.img/recovery recovery.img But I again stuck into a bootloop. Repaired again... I thought flashing a custom recovery breaks the phone, so I decided to just boot the recovery and install supersu. but again a bootloop in the end.
Is your bootloader already unlocked?

I have flashed the lastest stock ftf by flashtool, that is what I do after everytime I brick it while trying to obtain root. And if you mean switching to another user, yes it does.
that's good. it means hardware is fine.
it's your root method.

Hi, I am using P600 (note 10.1 2014 Wifi) XAR one
Yesterday I was trying to install magisk all day, but failed all
When I rooted device and instaled TWRP, in TWRP it made error number 1 and it says something like turn to stock boot, so I tried to reinstall stock firmware via Odin, but it didn’t change anything.
I guess it’s a problem with boot.img or the autoroot method I used.
So I tried to use fastboot to install TWRP without rooting, but this time it didn’t boot into bootloader from fastboot, it just restarted the tablet all the time.
So I tried to manually reboot into the download mode, but fastboot didn’t recognize the device then.
When I did it, I turnned on the USB debugging with no mistake since it’s just samsung.
So I booted into recovery mode(It can go into recovery mode without problem)
Then tried option “reboot to boorloader” and it just restarts the tablet again.
I guess something corrupted boot.img or bootloader somehow, while I was rooting or something.
Can I get factory boot.img and solve it? Or when I install stock firmware via Odin does it also fix boot.img and boot loader?
I tried to install stock firmwares and factory reset several times. It didn’t help anything. It did unroot or turn the recovery to stock recovery, but couldn’t get into bootloader.
Can anyone please help me or give me advice to solve this problem?
Bump
My S7 Edge (G935F) was rooted, but with a stock Nougat that kept negging me with Knox, so I got to change that Nougat to this Oreo ZTO-G935FXXS3ERLA_G935FZTO3ERKA-20181212.zip one. Everything was great until yesterday when I had the great idea of turning off OEM Unlocking. I didn't know what I was doing. Then I got the Custom Binary Blocked by FRP Lock. So I just reflashed a full ROM (instead of just the AP) and now I have no Recovery and every attempt to flash TWRP (last 5 versions or any other recovery.img) with Odin 3.13 has failed. It loads "recovery.img" then fails. I'm stuck with the "No Command" eternal loop.
I've scoured the Internet and found no solution yet. Please, help me save my only phone. At this point I just want it to function as a phone again.

Reinstall the Odin, Reinstall Samsung Drivers and try reflashing your ROM
Title.
After playing around with root and some custom ROMs i wanted to return to OOS, I had a few troubles doing that but eventually I succeeded.
I still wanted to have root access though so I tried going to flash TWRP, but was met by the message "serial_mismatch" followed by a system reboot.
This is persistent, regardless off physically trying to boot in to bootloader or through adb.
Fastbootd works, I can flash stuff with success but it seems like it doesn't actually flash since I can't boot into TWRP after flashing it in fastbootd.
I tried mtkclient, both on windows and on livedvd, my device gets found but on windows I get handshake failed until it ultimately reboots and on livedvd it gets stuck on "trying kamakiri2" endlessly.
Also, my safetynet check fails, even though I am on stock everything without root!
Any thoughts on what I can do here?
All help is greatly appreciated.
Hi there, what version of OxygenOS are you currently using?
Currently on 12.1 latest update (DN2013_11_C11). I tried the downgrade packages but as I can't access recovery or fastboot I can't downgrade either.
Please try this method: https://community.oneplus.com/thread/1596759 After downgrade you will have option to relock your phone and safetynet should pass. Let me know if it helped.
Thanks, already tried that but it fails to rollback as well
