How To : (If you never update OTA then go STEP 1, else go STEP 2)
- BACKUP YOUR IMEI FIRST (on twrp and backup it to another storage or cloud)

STEP 1
- boot to fastboot mode
- flash twrp / ofox command type on minimal adb fastboot "fastboot flash boot nametwrpfile.img" (make sure the twrp file on same folder at the minimal adb fastboot folder)
- press vol + & power

- reboot to "BOOTLOADER"
After reboot to bootloader,Device will be in fastboot.
- flash vbmeta " fastboot --disable-verification --disable-verity flash vbmeta vbmeta.img " (make sure the twrp file on same folder at the minimal adb fastboot folder)
- reboot "fastboot reboot " ( if success booting up to system go to STEP 2, if not success, read again from start )
STEP 2
- no need to setup anything, you can skip all that MIUI Setup
- reboot to twrp recovery, press vol + & power
- Format Data
-Yes
- install / flash Custom rom with check automatically reflash TWRP after flashing a ROM checked
- reboot ( If you skipped STEP 1 and not booting, back to fastboot or TWRP, then Go to STEP 1 first, if can't boot to either TWRP / Fastboot, Then you need MTK Bypass + SP Flash Tool)
- ( If you DONE STEP 1 but still no luck check SPECIAL CASE )
- DONE
SPECIAL CASE
if your phone bootloop on mi logo, then do:
- reboot to twrp/recovery, press vol + & power (wait it, be patient)
-If not boot on TWRP, Go to Fastboot
-Reflash TWRP [fastboot flash boot twrp.img]
-Now Boot in to TWRP
- install image boot.img on boot partition from miui rom you have used on first step (see above)
- reflash twrp, install image twrp.img on recovery ramdisk
- [Even if you go to TWRP Without Reflashing again,you still need to flash boot.img on boot and twrp on ramdisk]
- reboot system
- setup phone with ur mobile internet data (if the custom rom have gapps), cause ur wifi bluetooth hotspot are died
- go to twrp again, install custom kernel to fix bug wifi hotspot bluetooth (but u can't instal yukina starlight, it will make bootloop, use another I Will Recomend Yukina Stamine)
- done u can reboot system
N.B. - If You are in MIUI 13,Then it will won't Work,First Downgrade to MIUI 12.5.xx
N.B. - Just Do Normal Format,Dont Wipe like Delvik,cache,System,Vendor etc.
N.B. - Try To Take All Files(Twrp.img,boot.img,miui recovery.zip,Custom rom zip, custom kernel.zip) In your Memory card and Avoid Use OTG
