Hi! Can someone help me with unlock full bootloader( to install twrp and sucessfully root)? - Samsung Galaxy J4+ Questions & Answers

Hi!
My device is a J4 ( SM-J400M J400MUBSBCUC1 (B11) ( March 1 2021) )
I've been trying to root it, but failing
I'm trying to use the magisk method, but when I tried to install twrp via Odin this happens.
A friend of mine told me that it's because my OEM is not fully unloocked, but I already unlocked via devolper settings on the config menu, but when I enter recovery mode, doesnt appear that green screen tell me if I want to fully unlock to hold Volume Up, but instead he give me those options instead.
When I enter the bootloader via those options the odin fails to install the twrp like the first image.
Can someone help me ? :~
Thank you so much!

Is up allowed? need some help plz xD ~~

Is your bootloader already unlocked?
Phone stucks on "Entering recovery" screen
Hi guys
First of all, I'm absolutely new in this theme (rooting, installing custom recovery image and etc.).
I want to install CM12 on my HTC one S and due of this have done few steps (first and second) from following theme http://forum.xda-developers.com/showthread.php?t=1583427
Both of this steps completed without any errors (bootloader unlocked and recovery image TWRP 2.8.6.1, as recommended, loaded into smartphone).
But when I tried to enter into recovery menu or mode (I don't know actually ) smartphone stucks on loading screen with messages "Entering Recovery..." on the top and "This build is for development purposes only. Do not distribute outside of HTC... blah blah blah" on the bottom. I have waited for almost 20 minutes but nothing happend.
Neverthless, I can reboot smartphone into normal mode without any troubles.
Please, help me guys. What I should check?
Thanks in advance for your help!

[Completed] Vodafone Smart prime 6 bootloader issues

A friend of mine asked me to flash him a custom rom for his Smart Prime 6.
as I am myself a beginer I thought I should first install a custom recovery .
So I booted up the phone, activated developer settings ->usb debuging
And whenever I try the "adb reboot-bootloader" the phone will get stuck on a black screen which only says android (at this point it is not recognisable by "fasboot devices" )
I also tryed using flashify to flash a custom recovery ,but as it seems , the phone keeps losing root access after giving it with apps as Kingroot or iRoot
Is there any way to flash the custom recovery or get into the bootloader?
Greeting,
Thank you for using XDA-Assist, you might get more help by others expert in here Android/Help

[Completed] TWRP - Recovery is not seadroid enforcing Set warranty bit : recovery

Hello, I am sorry if this is noob question, but really can't find way to fix it. I am trying to install TWRP for J500F(TWRP-20150710-UNOFFICIAL-J5lte). I am using ODIN 3.12.5. It says Pass/ Succeed, but when I try to use it. Turning off the device, then Vol up+home+power button it stuck to this message. I can still use the device after restarting it. When i return the stock firmware I can enter in the normal recovery.
P.S same happen when i try to cf auto root
Hi !
You can try to flash the official twrp available on the twrp website for your device
Good luck !

Now I can't use recovery mod because it's giving me this: Error!
Function No : (Func_Boot_RECOVERY)

I've tried to use multi tool giving me error with any writing to device:
Faild remote command not allowed
Note: I'm still able to access normal mod, but it's hard, I've to try ton of times pressing buttons to boot to normal mod.
Please any help dears.
Update:
Now my device is not booting to nermal mode anymore.
I kept flashing through unbrick tool in multitools.

And now I'm stuck on recovery mode (also with same error above) and fastboot mode when I restart and connect device to pc keep pressing volume down.

Which firmware you were on before issue?
No I didn't
As I said trying to restore my backup through TWRP but was in internal SD., that's it.
My real model is L12.
Version, I don't remember but it was on android 5.1.1 EMUI 3.1
Now I just used Sd method and recover device with last 4.0.1 EMUI for devolvers, but no Arabic language.
How to go to another firmware?
What is the best, satable one for my device?
And is there a good custom stable rom, especially if android 7 ?
Please full answer if available
Thanks again
