Use 7zip to unzip firmware. If the unzipped file is the same as that in the picture, download newflasher v52 and put it in it to run.

Yeah turns out what I have is the source code for that version. I just downloaded the US version someone backed up here and I'm hoping that it works on my UK device without too many issues

ROM has passed the SafetyNet check.

I guess we need twrp for infinite reboots if change something and the system does not like it.
Otherwise you just have to reflash and lose everything.

Does this rom have built in signature spoofing to install microg?

---

been really hanging to try this one, but also been looking on and off for months now for said 61.0.A.23.20 rom with no luck.
any chance someone can point me to a download link for this? I had already upgraded way past this version using OTAs and now I'm just stuck with this.
