I have only updated to 126.96.36.199 because they have released fastboot versions from the mentioned version. I am willing to install the unofficial TWRP for Joyeuse (or Curtana, as I have read) because there is no official TWRP yet. I only have a problem with the requirement of deleting all my phone's storage to install the TWRP because I have important files on my phone, and it's inconvenient for me to delete everything just like what I did to install from Stock to EU Rom. Any help regarding my issue is much appreciated. Better if they rerelease fastboot versions. Is it also confirmed that the call recording function is removed from 188.8.131.52?
