No longer root access - Galaxy Grand 2 General

Hi guys, I am new here. I rooted my grand 2 and installed cm 12.1 rom . My phone is working properly but I no longer have root access. It is even confirmed by Root Checker(It says "Sorry! Root access is not properly installed on this device."). I tried to flash superSU from the recovery mode. But I cannot even go to the recovery mode manually(Vol Up + power button + home button). I had installed CWM 6.0.5.1 while rooting the device and now it seems it has been erased. Whenever I try to enter recovery manually it takes me to the download mode. I tried flashing CWM again using odin. But it keeps failing. I do not understand where the problem is. Please help!!!

In CM12.1 First enable Developer Options in Settings by tapping Build Number 7 times and then on Developer Options

Good day!
I have a strange problem, After upgraded from 4.1.2 to 4.3 (i tryed XWUGML4 and XXUGML2) and rooted device (from odin PC)(used I9300-4.3_ml2-CF-Auto-Root.tar.zip and other) i cant encrypt device.
My steps:
1. Wipe data/cache
2. Install 4.3 (odin PC)
3. simple configure
4. Install root (odin PC)
5. Install password on lock screen
6. Plugin power cable
7. Try encrypt
8. Phone was reboot and nothing. Phone asking password only when it complete booted.
9. Go to security menu and see what phone is not encrypt.
When i was install 4.3 and try encrypt phone i have no problem.
I think what when i install root something goes wrong. Maybe root change files. At 4.1.2 i dont have this problem

[Q] I9100G didt know that he is an I9100G ! ! ! ROM FLASHING PROBLEMS

I own an Samsung GT - I9100G but my Problem is that when i try flashing a ROM my Phone always say following:"This package is for "i9100g,GT-I9100G" devices; this is a " " ... "
THINGS I ALREADY TRIED :
I already tried to flash the OmniRom and CM11 I also toggled the signature varifacation on/off an in both cases i didnt worked.
I tried to flash both ROMS with CWM an TWRP but I got the same Result.
Flashing a Root Kernel and TWRP&CWM worked fine.
I think the point is that my Phone "forgot" what device number he had so he block all attempts to flash a new ROM to protect it. Normally it will fill the space after "this device is a ... " but it didnt.
Years ago I flashed CM 9 or 10 and this worked.
I hope someone could help me because I´m sick to see the TouchWiz UI.

Help With Installing TWRP

Hello guys, I have been out of the customizing game for awhile and have very recently gotten ahold of a completely stock Verizon S4 that was fully updated to the OF1 software (5.0.1).
I followed these root instructions here: http://forum.xda-developers.com/galaxy-s4-verizon/general/samsung-s4-i545-verizon-of1-root-t3254434 and that was successful. I installed "Root Checker" just to make sure that root was successful and it told me that it was. I successfully installed BusyBox and then installed the TWRP Manager app. I selected my device from the manager app and it downloaded the TWRP 3.0.2.0 for the jfltevzw, and then it told me that is successfully installed that Recovery.
The phone will boot regularly just fine. However, whenever I try to go into Recovery mode (power button + home button + volume up) I get a "Start Up Failed" splash screen with the yellow triangle and the tiny text in the top left that says, "Secure Fail: Kernel."
I have included the necessary screenshots so that you guys can see all of the necessary phone information. Did I miss a step? Should I try to manually install TWRP via Odin? Thank you in advance for your assistance.

your bootloader is OF1. you can't use TWRP because the bootloader is locked.
There is no way to use it. You must use FlashFire.
To fix your issue you need to Odin this file: https://www.androidfilehost.com/?fid=24415232478677245
Thank you for the answer!

@Hoeist
Did you use Easy Installer
to flash /e/OS?
Yes. On the meanwhile I discovered what's wrong.
so instead of booting to twrp (winteam), as explained in the setup,it boots in the standard recovery.
I'll try it again by first installing winteam. But what I'm wondering, the latest version of eos is oreo. My phone is android 10. Will it give an error or worse if I flash a oreo zip?
I'm net to jailbreaking phones so many things I don't know.

There are several checks in the firmware to see if your phone has ready for the update. It seems that it doesn't allow the update.
If you exit recovery mode, are you still able to boot your phone normally ?
Have you downloaded the firmware from your country's Oppo website ?
yes i can still reboot and it is from the official oppo site from my country
