Hi, I installed the stable version og MIUI8 for Maxpro last week, dirty flash over MIUI7 using TWRP. (Installed xiaomi.eu_multi_MIMAXPro_V188.8.131.52.MBDCNDG_v8-6.0.zip). Deleted Cash/Dalvik after flash. Everything installed before the upgrade was kept. So far everything working great! I have not found a single bug, it seems rock solid. After many years using Samsung Notes and the S7 Edge as the latest, this has been a joy! The performance of the Max has been above and beyond expectations, all at a fraction of the cost of the Samsungs. Thanks to everyone contributing to this great ROM, keep up the great work!
