Hi every body!
Handset configuration before issue

Problem origine
2 days ago, the phone was been fully discharged...after charged and power on it, it started booting and stop at MIUI logo.
Problems
1) Error notification from TWRP " E:failed to mount /data (Invalid argument)", " E:failed to mount /cache (Invalid argument)"
2) Flash with success an other ROM (miui_v4.4.2_hwp6-u06_4.9.22.zip, miui_p6u06_4.9.22_2mmb9x1pd2_4.4.zip or miui_p6u06_3.10.11_kjqvk609mo_4.2.zip, miui_p6u06_sxpatch_3.12.22_027b7e7601_4.2.zip) but stop booting at MIUI logo???
3) Flash failed with ROMs example : HYD52ROM_P6_V3_OMNI.zip and PA4.6-BETA4-20141008.zip
3) device at recovery mode ==> adb devices return good handset ID, but in bootloader, fastboot device return ?????? fastboot <==> so, what is wrong?
4) Flash stock ROM using dload folder from SDCARD failed ???
Questions:
1) Any idea to perform a full memory erase (tools, method,...)?
2) How to flash stock ROM?
3) Any idea to remove actual TWRP recovery?
4) Why flash ROM from TWRP is success and boot stop at MIUI logo???
5) Any help welcom to fix this issue!

Re
Maybe first of all you two write the steps performed for flashing Lollipop Roms? I've tried all the Lollipop Roms compiled for SXS and nor,ally I used to do this way:
1. TWRP recovery (but CWM also worked)
Install TWRP recovery in FOTA partition using Terminal apk provided your phone is running on 4.1.2. kernel supporting TWRP recovery. Flash kernel from ROM zip file prior entering TWRP (this step helps avoiding an error like "update binary...").
2. In TWRP recovery - Advanced - wipe everything but sdcard. In Mount section unmount everything but sdcard.
3. Flash the ROM and wipe Cashe&Dalvik
4. Flash appropriate GAPPS, wipe Cashe&Dalvik and reboot.
that's all

Need help flashing my Mi Mix 2

Hey guys,
im completly new to this flashing thing an i think i made a big mistake.
I tried to flash a new miui version (Global) via the already installed TWRP on my phone.
But that didnt quiet work, after the installation it just booted back in TWRP and i couldnt get the phone to do otherwise.
I googled a bit and found this tool called MIFlash (ver. 2017.4.25.0)
i also downloaded the fastbood rom from the Offical miui site and saved it on C: in a folder called rom
So i put the Phone into Fastboot and tried to flash it with MiFlash but in the end i got an error ( error:FAILED (remote: Check CRC failed))
And after that i couldnt even wipe the Data via TWRP i got an error there too
"Could not mount '/data' and unable to find crypto footer."
"Failed to mount '/data' (invalid argument)"
"Unable to recreate /data/media folder"
"Unable to mount /data/media/TWRP/.twrps"
"Unable to mount Storage"
PLS HELP!!!! :crying:

You need to use this twrp. Then it will work. About twrp errors: just ignore...

I've already used also that TWRP version
twrp-installer-daisy-3.3.0-0-offain.zip
KO
