No OTAs for me but I can confirm the script is running smoothly on Poco F3 now. Below is the step-by-step:
1) Download the xiaomi.eu_multi_HMK40_POCOF3_22.7.21_v13-12.zip to the internal storage
2) Settings \ My Device \ 13 MIUI version (Icon) \ Updater Menu - Top at Right (...) \ Choose update package \ Select the downloaded file from Step 1, <ok>, <ok>, <ok>, <Yes> then Reboot to Recovery
3) TWRP Splash Screen \ Insert PIN
Not sure what is happening here I have a mi10 and since the last 2 updates my phone seems to have lost all associations of file types with apps. When I click on links now instead of opening the associated app the browser opens. Anyone else having a similar issue?
