Hi there!
First you should be able to recover the original Imei of your phone by flashing with Chimera Tool and keeping the same binary. Take the test and upload the result of the operation

Second Option:

You should re-flash the device with different firmwares one by one and check, whether modem is correct (not Unknown).
If after writing of all firmwares, which You have, problem remains the same - most likely,
this is HW problem (problem with eMMC flash chip).

Steps to try to rebuild the EFS folder with a merge file:

1. The first thing is to have our phone with imei at 0000000 or Unknown
2. Root, and activate in addition to USB Debugging the OEM Unlock
3. Once the root is done we proceed to install a Root Explorer and access the EFS folder and we are going to eliminate
all the content except the folders "FactoryApp" and "prov_data" and we turn off the phone.
4. The next step will be to flash via Odin with the Factory_Binary (Combination File) of the model to work with.
5. Once the Restart is done, press the "IME" button and a keyboard will appear with which we proceed.
to verify the IMEI with * # 06 # and we will see that our imei is already correct again
6. We proceed to flash with a Stock Rom and this is it, IMEI Recovered and ready to continue working.
