Flashing stock rom via odin failed..fap lock?

Hi,
I tried to flash a stock firmware today using odin, however it failed. On my phone it says custom boot binary blocked by fap lock, but i am flashing stock firmware only. I have never rooted or unlocked the bootloader. Now my phone is stuck in the downloading mode. How do i fix this or successfully flash?
Regards,
I tried everything, now i get a secure lock error?
To recap, i have a g935w08 and i was trying to flash the BTU firmware (G935F) which i downloaded from samfirm, i used all the BL, AP, CP, CSC (used regular CSC) and it refuses to work. I am using odin 3.12.
Who can help me with this?
Try odin 3.11.1 as it says on the download page, failing that, try and flash your original firmware.
Instructions at the bottom of this download page: https://www.sammobile.com/firmwares/download/116121/G935FXXU1BPLB_G935FBTU1BPK3_BTU/
I gave up. Could it be due to the fact that i am trying to flash a G935F firmware onto G935W?
yes that's very possible, in your post above you said you have a G935F ?
"To recap, i have a g935F and i was trying to flash the BTU firmware"
@Seanie280672 I have updated it now. Does anyone know if this is possible?

A310F flash fail, Odin, brick, no 4parted firmware nougat avaailable, how to go on?

Had A310F with custom ROM, then went back to stock marshmallow.
Now wanted to go for latest Nougat with the marshmallow rooted and twrp on.
Samfirm only gives my one oart firmware which does not fir in ap slot on odin 3.12.
using 4 part nougat carrier specific not free one it fials on flashing.
What is the way now to get a stock android 7.0 device here with which firmware please?
does flash fail due to downgrade?
think i deleted something in marshmallow rom to make bootloader security somewhat fit to downgrade
Try to download the firmware from sammobile.com i think you can't downgrade just download another stock firmwaee for the a310f (your device) and try to reflash via odin

Failed official firmware install (SM-T580)

My device got FRP locked and so I used Odin to flash the official firmware from Sammobile and now I have T mobile menus like personal hotspot in my settings apps even though my device is the Wi-Fi only tab A 2016.
Here's how I got here:
I flashed the correct firmware, and in Odin I flashed the ap file, that's all. It succeeded but when installing updates, it said no command and went to the stock recovery. I factory wiped and rebooted.
How do I get rid of the T mobile menu's?
Any help would be appreciated
FIXED: Reflash in Odin with BL and CSC file
Same
I got the same problem, fixed it by flashing ap and csc
I live in the US and chose the XAR version from Frija
Now my lockscreen doesn't work, how do i fix it?

Stock rom

Hello can I flash stock rom via odin without unlocking bootloader because I want flash xeo rom . Frp lock off
My device is samsung a40 with android 11
Stock ROM always at any time can get flashed by means of ODIN.
So I don't need to unlock the bootloader?
you dont need to unlock the bootloader
just flash it by odin

[Fixed] [T580] Custom binary blocked by frp lock

Update:
For anyone who got the same problem as me:
Flash the exact same stock rom with odin (bl, ap, csc not csc_home).
---------------------------------------------------------
Hello,
So i made a mistake to turn off the developer options and i think by that also oem unlock, and on a restart i got Custom binary blocked by frp lock.
What are my options now in 2022 also is it possible to complety remove the Custom binary blocked by frp lock so i wont happen again in the future?
I still got the stock recovery because twrp wont mount anything but i think that is because i needed to flash the dm_verify zip to make that happen so i stayed with stock recovery and patched it with magisk.
I can boot in to the stock recovery and i can boot into downloader mode.
Hope someone can help me with this.
Info:
Samsung Galaxy Tab A 2016 (SM-T580)
Rom: T580XXS5CTK1_T580PHN5CTK1
Android: 8.1.0 Stock samsung rom
Recovery: Stock
Magisk and Busybox installed
Let me see if I've got this right. Your post says you have a stock ROM and recovery but with Magisk installed. With full stock and no Magisk, all the FRP lock should do is require you to enter the Google Account login and password on first boot. So have you tried a factory reset in recovery to get rid of Magisk? Then once booted, you can turn Dev mode and OEM enable back on and go from there.
Hello, thank you for the reply
But it was a Custom binary blocked by frp lock so no google account frp lock.
But i got it fixed by just flashing the complete stock rom with odin and then flashed twrp 3.6.2 with dm_verify 6.1 zip.
