I just
successfully installed the Xiaomi.EU Stable ROM SKACNXM-13.0.13 using TWRP.
I don't use Extended memory (12 GB+3GB) on the phone (12GB are enough) cause I heard that sometimes extended memory makes troubles while using TWRP.
I used newest TWRP version [BOOT]3.6.2_12-Mi11Ultra-Mi11Pro_
v5.1_A12-star-skkk_8f73ce5e for my Mi 11 Ultra, downloaded from
here
(After downloading I checked the MD5 checksum - I think it's a necessary step to make sure that downloaded file is not broken).
I had downloaded the ROM SKACNXM-13.0.13 directly to the smartphone via the
updater and then checked the SH1 and MD5 checksum. The checksum matched also the download Rom file from the website:
https://sourceforge.net/projects/xi...files/xiaomi.eu/MIUI-STABLE-RELEASES/MIUIv13/
I didn't restart to Recovery via Updater.
I restarted to TWRP via
extended Power menu (can be enabled in developer options) When I restart phone I have 3 options: Restart, Restart to Fastboot, Restart to Recovery.
My previous version of TWRP was 3.6.2_
12-Mi11Ultra-Mi11Pro_
v3.7.
From this TWRP version I updated directly to TWRP version [BOOT]3.6.2_
12-Mi11Ultra-Mi11Pro_
v5.1 by flashing it to Recovery_Ramdisk.
(If someone hasn't TWRP for A12 already installed, TWRP can't directly installed for Mi 11 Ultra. It must be booted temporarily first via Fastboot Mode and when it is started and the settings are done it can be flashed to Recovery_Ramdisk and then phone should be restarted to Recovery after)
After flashing TWRP I restarted the phone from TWRP into Recovery (TWRP) again instead of restarting to systém.
(I think it is also an important step after starting into TWRP from system - to boot again TWRP directly from TWRP with Restart Recovery, like
@katerpanne described
here before flashing a Rom or another zip file)
After that, using the new TWRP, I selected the Rom zip and flashed it. The process went smoothly without any error message. I only updated, which means I didn't do format data. But I cleared Dalvik cache before restarting. The reboot took a while and now I'm happy
Flashing TWRP and updating the ROM is very well described (MI 11 Ultra = A/B device) here:
