How To Update 6.1.15 Official Chinese Rom To Roms?

Apr 30, 2016
Hi to all, for about two years I weekly update my Mi4 LTE with Rom weekly release, last week, however, during the last update to the 6.4.21, something went wrong, and the phone was useless, I had to make a miflash and now I have on my phone the official Rom "MIUI7 6.1.15 | beta".

How do I get back to your rom, should I install the TWRP recovery manually or can I install your rom 6.2.25 (the last rom before it was required TWRP) in order to replace the original recovery?

Thank you
