Thanks for the reply, I have 2 questions may seem to be silly.
1. Do we need twrp or can be flashed using the stock recovery and then wipe cache and data as redmagic 3 international version dosent have Twrp.
2. Only need to flash the system.img file and if no twrp then can it done using adb.
Thanks in advance for the support and help
Thank you (and so many more people...) very much for this build. I installed it on my Samsung A8 (the vanilla version) and it works well. Some quirks though. I installed microG (following the microG site, installing all the necessary components), and doing the check, it didn't tick all the boxes. Yet, using the spoof checker, it says the ROM is spoofing enabled. Using Aurora (Google Play fake..), I can install apps from the store. So question is: is the ROM (GSI) spoofing enabled?
Thanks. I did try nanodroid (https://downloads.nanolx.org/NanoDroid/Stable/NanoDroid-patcher-184.108.40.20600102.zip) but it gave an error (ERROR 1) when installing from TWRP.
Having said that, when installing aurora (from F-droid), I still can install apps from the appstore using aurora's fake gmail address....
