Hi,

since I'm not 100% regarding the procedure and want to make sure I don't do any major errors.
I have a an 'older' weekly rom installed with the fastboot method and I want to update to the newest weekly rom.

How do I need to proceed?
Would I need to install/flash TWRP first and then proceed with the regular update procedure with the new rom?
I assume this is the right TWRP version: link

Thanks in advance for a reply.

@gogocar62- thanks for the fast and clear feedback.

now I am stuck at step 4 - somehow my pattern is not accepted.
I changed my pass to a pin - still the same issue...

removing the lock screen password did the magic ;)

Just a silly question, to install TWRP roots the phone by itself? Or just allows to it? And my user data, remains or I need to save it before?

TWRP install is not directly linked to root, you can do one without the other.
You can install TWRP without loosing data, but obviously, doing a backup is always a good idea.

Okay so when phone is connected and booted ./adb devices sees the device. If I reboot to fastboot via it, the phone can't be seen. What am I doing wrong?

Okay fixed it to get TWRP installed. I had to download the latest MI Unlock Tool and install the drivers with file 'MiUsbDriver'. This then allowed the device to be seen in fastboot correctly. Then installed TWRP and OS updated through TWRP.
