It's not worked in my case. But, (https://forum.xda-developers.com/t/realme-3-recover-from-soft-brick-boot-loop-guide.3920401/) this method worked in my case so if you face the same problem or the method not working try this. Hopefully it can help you to fix the problem.
The device that I used: realme C3 (Bangladeshi version or global version or narzo 10a in India).

Good day!
The number 3. tool seems not to work on my end,
I did have the DLL error so I downloaded it,
but after downloading it I got this error.

Download Not Complete error 0x992566 (SOLUTION WITH SP FLASH TOOL)

The 0x992566 error is because when using "SP flash tool" and using the "Format all" option it causes us to erase all partitions on the device and if you thought that you bricked the phone and it won't react anymore, relax, because

it's an easy fix for that you have to install the "Oppo_Custom" partition but keep in mind something:
If you got to have the "NvRAM" and "NVdata" partition you can recover the IMEI but if not then this tutorial will only fix the system but will not recover the IMEI (it is better that after restoring the device you go to a support center to have them Installed).
STEP 1: download the file ZIP
Download Not Complete Solution.zip
drive.google.com
You must download the ZIP file, it contains all the files to be able to restore the phone (WARNING: DO NOT ATTEMPT TO DOWNLOAD FILES FROM OTHER SITES, YOU MAY END UP DAMAGING THE DEVICE)
Step 2: you must unzip the file
Step 3: open the "ByPASS" folder and open the "Lib USB" installer and install it.
Step 4: open the executable "mtk_bypass_rev4" and when it is open press the "BYPASS" button.
Step 5: now turn off the device (wait for the countdown to end) and hold down the volume + and volume - buttons while the bypass waits for it to recognize the device i.e. by holding them down you connect it to the pc, otherwise it will not go into "BROM" mode (but if it fails to connect you should open the "Lib_USB" application and when you apply these steps you should hit the "Mediatek USB Port" option and hit "install device").
Step 6: after bypassing the device you should open the "SP Flash Tool" folder.
Step 7: now in the "Download Agent" box select the "Choose" option and select the file "DA_6765_6785_6768_6873_6885_6853.bin".
Step 8: now in the "Scatter -Loading File" box select "Format all + Download scatter".
PLEASE NOTE: the phone must be in BROM mode and connected to the PC and make sure that the "Oppo custom" partition is selected and you have not moved it to another place.
Final step: you must change the "Download only" option to "Format all downloads" and press the download button.
If everything went well in the loading bar will start to load the system to the phone and you should wait 10 minutes or more (depends on the speed of the pc) after the process is finished a window with an arrow will appear.
Disconnect the device and turn it on with volume + and the power button.
NVRAM AND NVDATA
EYE IF YOU DON'T HAVE A COPY OF YOUR NVDATA AND NVRAM OF YOUR DEVICE SKIP THIS PART AND GO TO A SERVICE CENTER TO RESTORE YOUR IMEI.
If you have a backup of these files, you must open in the unzipped file the folder "NVRAM Scatter" and open SP Flash Tool.
Step 1: in the "Scatter loading file" part select the "Nvdata Nvram Scatter" file (it is located in the "nvram scatter" folder).
Step 2: after selecting it, you should scroll down and select the Nvram and Nvdata partition and then select its partition file.
Step 3: select the "preloader" partition and this will open a window and in it you should go to the "RMX2020 Stock ROM" folder and select the "preloader_oppo6769" file.
Step 4: now open the "MTK bypass" and you should put the phone in "BROM" mode (remember to turn off the phone and hold volume+ and volume- and connect the phone to the pc without releasing the buttons i.e. holding down you connect it to the pc, otherwise it will not go into "BROM" mode).

will oppo_custom.img file work in my rmx 2117 device ?

It depends, since each model has different writings, and that could terribly affect your device, you should search for your model on the web or look for a dump file of your model, oppo will appear there Oppo custom and you will have to copy and paste it, and don't even think about taking an external NVRAM OR NVDATA file because that will damage your WiFi connectivity, but it is fixed by formatting

Question HELP

my device is locked in fastboot after flashing gsi, i tried all but nothing, so i locked the bootloader, i know i'm dumb but i was and i am desperate, solutions? idk if there is still a rom in because it was empty and i tried the fastboot method to reflash rom like flash boot.img and vbmeta.img and others (nothing changed).

UPDATE, i unlocked the bootloader but the problem is still here, i tried to flash rom with fastboot but it fails with system and vendor, i think that's the problem.

logs? photos? how you flashed? what you flashed?

Supposing your bootloader is unlocked, just follow this guide taken from this Mi official page.
Method 2: Fastboot Update
Note
A Windows PC/laptop will be needed for the following steps. Make sure that your device is fully charged or has enough power for this process. This guide will help you update your device to the latest MIUI ROM version. All user data will be purged in this process. Please back up your data and think twice before proceeding.
STEP 1
Download MIUI ROM Flashing Tool (Size: 66.7 MB)
STEP 2
Select the right MIUI ROM version for your phone:
★ Redmi Note 11 [spes] Global
★ Redmi Note 11 NFC [spesn] Global
★ Redmi Note 11 NFC [spesn] Europe
★ Redmi Note 11 NFC [spesn] Russia
STEP 3
Turn off the device. Press the Volume– key and the Power button at the same time to enter Fastboot mode. Then connect the device to the Windows PC/laptop via a USB cable
STEP 4
Double click on the downloaded ROM file to decompress it. Open the file folder for the decompressed ROM pack, and copy its path on the computer.
STEP 5
Decompress the MIUI ROM flashing tool downloaded in Step 1, and double click on it to install (if there is security warning, select 'Run'). After installation is completed, open MiFlash.exe and paste into the address bar the ROM file folder path copied in the last step.
Click on the first button (circled out in yellow) to Refresh, and MiFlash should automatically recognize the device. Then click the second button (circled out in red) to flash the ROM file to the device.

STEP 6
Wait until the progress bar inside MiFlash turns fully green, which means the ROM has been successfully installed. Then your device should automatically boot to the new version.
If the flashing guide could not help you, please download Mi PC Suite here (after Mi PC Suite is installed, make sure that your phone is in fastboot mode, connect your phone to a computer, and select the correct ROM file to flash).

I finally solved, i unlocked bootloader again with mi unlock and i followed this instructions, thx
