I understand. Take your old rawprogram3.xml file (with the "oplus" line) and rename the following files in the firmware's IMAGES folder :

- oplusXXXXX.bin > oplus.bin
- dynamic_nvbk.XXXXX.bin > dynamic_nvbk.bin
- static_nvbk.XXXXX.bin > static_nvbk.bin

I don't know of any method other than QFIL for hard unbrick. How did you hard brick your phone ?

I was trying to get back to RUI4 from LineageOS using this method (https://forum.xda-developers.com/t/...date-file-unlocked-bootloader-needed.4597237/). I have got several errors in slot b and Reboot the phone from fastboot, from then it's not opening up phone is completely black.

Did you change sparse parameter for userdata.img from true to false into rawprogram0.xml file ?

For the super.img, that's just a warning, not an error.
