Thx for all alibei, you made an amazing job. What's you're new phone ?
I have the realme GT Neo 2, but I don't build for it (want in future), then I have the Narzo 50 5G which I was able to unlock before the bypass got patched, so no one will be able to unlock as well. I currently build for the Realme Pad (but the hardware is not worth to buy)
