You need to update your phone to 6.12.22...then download Android 7 to your device and install via the updater app...after installation unlock your bootloader again and install TWRP 7 Libra for Android N

no need to wipe data???
 
Hey, i have the latest xiaomi eu stable rom with android 5.1. so can i just update the newest rom with android 7.0 via updater app?

And do i have to have twrp for android 7.0 before updating?
 
Okey, but im in stable rom so can i go into dev 6.12.22 just like that without dataloss
 
Many thanks for your help, but...after MIUI 6.12.22(all ok)

i try to install from updater the zip "xiaomi.eu_multi_MI4c_7.7.20_v8-7.0.zip"

and phone reboot but stay freezed with white logo MIUI on screen and nothing appear.
Power off and boot, the miui don't change and the .zip i s deleted

I try also to unlock another time the device and i have installed TWRP_libra_7.0, then updater and zip but is the same.

What is wrong ? many thanx !
 
You need to install TWRP Libra 7 AFTER installing Android N...not before....
Yes I try before libra 7 but freeze , is possible that i need another version of TWRP before install zip, a good version?

So can you get into twrp?

Wipe cache and danlvik before installing zip file. Go to twrp -- wipe--- cache and dalvik cache

Do nyt wipe system!

Steps to install are following:

Wipe cache and dalvik.
Proceed the update via updater.

So can you get into twrp or not? And wait patiently, it will take som time to update. For me almost 1 hour because i got stucked on mi logo with update process ready. I had to reboot it, but i waited because there is change to get it har bricked if you do something very wrong

I dont get it now...

So you tried install dev or stable rom? And you installed it, then you get stuck on mi logo but you flashed new twrp?

Can you go to previous twrp? I mean can you get into recovery mode now?

Ok i try your solution ;) later my results! many many thanx:)
 
Did you succeed?
Hello ! the (bad) results..
1-Install MIUI 6.12.22 before updating to Android 7.0..
2-Boot to TWRP...wipe cache and Dalvik
3-updater and install.zip xiaomi.eu_multi_MI4c_7.7.20_v8-7.0
4 the phone boot in TWRP, i see unpacking, then 2 error appears in red "unknow command or other" wa fast...the phone reboot alone every
minute and nothing in progress !!
 
Re boot into TWRP and select install...chose the .ZIP that you downloaded and swipe right to install...after installation wipe Dalvik and cache and reboot to system .....
What version of TWRP are you using ? Try updating TWRP to 3.0.2.0 TS.... before proceeding...

Like above, install zip, and do not reboot straight to system. Press back and then wipe cache and dalvik. Then reboot to the system
