system, data, 兩個cache, internal storage都清一清
清完再刷PE
PE刷完直接重開機試試

要使用格式化date分區喔，如下圖所示

應該是 twrp 的問題.
現改用 OrangeFox.

可是我也是用twrp啊，是不是版本的問題@@?

OrangeFox是建立在TWRP上 :flash:

recovery忘了問版本

可能.

我怕得是這個:

Xiaomi ARB

Xiaomi has broken ARB implemention which can brick your phone forever!

If your Xiaomi device has ARB, and you are on a MIUI ROM, then you had better tread very carefully if you want to change your MIUI ROM to a different MIUI ROM, or to a different version of the same MIUI ROM. Search on Google for "ARB", read and understand everything, and then decide whether you really need to proceed.

看了整串討論, 所以我現在都不大想刷機...

要找專用的twrp不是隨便的都可以刷.

Sanzium - hope you or anyone else who is reading this can help me, I am quite a newbie in this. I did it several times with different roms/devices but all went smoothly until now. I tried to flash the rom with the newes FW (MIUI 12.0.3 global and with a downgraded FW to the one in the original post) in both cases my phone went into a bootloop.
I did exactly the following (after unlocking the bootloader and enabling dev mode):
1. Flash TWRP through fastboot.
2. wipe -> factory reset + wipe data.
3. advanced -> sideload
4. sideload 11.0.9 FW + wipe-> factory reset + wipe data (tick wipe dalvik and cache)
5. sideload PixelExperience (with wipe dalvik and cahe ticked)
I performed it once with step 4 and once with a clean fresh stock rom of MIUI 12.0.3 without step 4.
In both tries the device went into a bootloop - what did I do wrong?

I am whiling to take a shot in building PE for MIUI12.0.3 (latest FW) but I will probably need some pointers as I have never cosumized an android rom before nor I know if the build would matter without
FW reverse engineering.
Thanks,
Click to expand...You probably need to format /data, specially if you are coming from MIUI.
What I always do when flashing Cepheus is:
1. Transfer files to internal storage
2. In TWRP: wipe > advanced > tick system, data, cache and dalvik
3. Flash firmware
4. Flash ROM
5. Flash Gapps
6. Format data and reboot
I usually only flash Magisk after first boot

-------------------------------------------------------

所以說 從最新的MIUI 12.0.3 global Mi 9 必須刷回 PE 當時的 firmware.

或著等更新的 PE 出來.

哪裡可下載 PixelExperience_cepheus-10.0-20201206-0801-UNOFFICIAL.zip ?
