How to install older rom?

[Mr.freezer]

I have problems with miui 11 and battery drain. Can anybody help me how to install older rom with miui10? I have tried to download older rom and install it through twrp.. installation done but phone does not turn on.. just MI logo... Downloaded the newest rom, installed through twrp.and phone works... But battery drain still happening

 

[Mr.freezer]

Since you are downgrading so to speak, you must format data to install the older ROM...

so I need to wipe and format all the data except system in twrp?

 

[Mr.freezer]

So I tried to wipe all data.. including system. Installed stabel miui11 but it does not turn on.. just MI logo.. wiped again... Installed weekly miui11.. runs fine... I am desparate... No apps installed, everything turned off and battery is draining 5-6% in an hour without using the phone

When flashing from beta to stable and vice versa, other than a wipe, you should also perform a format data.

In TWRP, after you had flashed your desired ROM, go to Wipe, then tap on Format Data. You will lose your data and hopefully, you had done a backup prior to this.

Use miflash and a fastboot rom to reset your phone. This will clean it and remove collected issue you got.

sorry man, you must flash the rom that belongs to your phone model. This is to say you don't flash the right version.
There is no risk with Miflash because it will always advice you are doing wrong without going to brick.
- Are you sure your phone is global?
- IS it printed on the delivery box?
- you may have a chinese version where your seller installed a global.
- Check all that points and find the right direction.
you will succeed!
Ps: I'll be back tomorrow, it is night here.

As LOLO9393 said, do you have this printed on the side of the box? Is your bootloader already unlocked when you purchased it?
