All things Mi - Siao Me

Today I'll talk about Xiao Mi Phone, particularly the Mi3W model. The problem I had was probably caused by me - as I was/am not sure about android, let alone it's booting technology. A friend had an old Mi3W phone sitting in a box - unused for years, built in 2013. He said it was un-usable so he gave it to me. It didnt boot up, but eventually I managed to get it to factory reset and upgrade to Android 6.01 by using the OTA method. Then I discovered that there were no Google Playstore, and thats useless for me. I decided to flash a custom rom, hoping that playstore shall be available. After flashing Mokee, it doesnt boot up ever again, always getting to Fastboot screen. But strangely enough, it finally booted into Mokee. All was fine, but still no Playstore. So I attempted to factory reset again from within Mokee. This created the infinite Bootloop with the Mi logo showing up and reboots again. But I can still somehow get into Fastboot. I attempted to MiFlash the Fastboot roms, which MiFlash said successful, but i can never boot right. Now the unit doesnt even boot up. pressing any combination of buttons does nothing. Plugging into Windows, seems like it keeps connecting and disconnecting from the USB. Plugging into power, there is a red blinking light.. I think this is like superfast reboot or bootloop. I'm about to throw the damn phone into the trash soon - and no more Mi devices in the future. its also know as the Red light of death. Siao Me
