How To Guide [ROM][MIUI][thor] Xiaomi.eu ROM for Xiaomi 12S Ultra

[shirozenx]

All the answers to your questions can be found in the posts above.

Thanks for the reply, I have read the thread a few times over, that's why I have posted my question as I'm confused, there seems to be the two methods and both works?

1. flash 13.0.8 via fastboot and update sequentially to 13.0.11 via twrp as mentioned by SirTAVARES

i flashed .8 via fastboot and then i've been updating via twrp (currrenly on .11) that was already in it.

2. directly installing v6.2 twrp and flashing the latest v13.0.11 via twrp as mentioned by you

Remove lock screen security
You must have Twrp installed.
https://forum.xda-developers.com/t/shared-twrp-by-skkk.4489561/
Use
[BOOT]3.6.2_12-Mi12SUltra_v6.2_A12-thor-skkk_003889f7.zip
.
Twrp
Wipe/format data type yes(if error, red , lines,reboot TWRP and format again)
Reboot TWRP
Put the zip in internal storage or use OTG
Flash rom
First boot takes time.
_________________________________________________________________________________________________________________________
Apart from the 1st rom, no more Fastboot.zip.
Updates are done via OTA.

just want to be sure if both methods work and if there's a recommended method for flashing for the first time from China ROM. thanks!!

Both methods work.
Fastboot takes longer.
Flash the latest version with TWRP and you're done.
Twrp 6.2 version
wipe/format data type yes
reboot twrp
put the rom in internal storage or use OTG
flash it

Thank you so much! Will go with flashing the latest with twrp then. Cheers!

Questions.

In the case of the latest devices, the weekly ROM of the old method (ex. 22.10.28) is not officially released.

Do you have any plans to release a new weekly rom (ex. 13.x.22.10.28.DEV) as eu rom?

Due to beta process adjustments on Xiaomi's side, we will stop releasing "old" Weekly ROMs (22.10.26 is the last "old" Weekly release). Next updates will be based on "new" Weekly releases (like V13.1.22.10.26.DEV) and may include an Android 13 upgrade in near future and new devices.

hello everyone, why whatsapp statuses, namely videos, are slowing down?

Same here, latest WhatsApp and 12S Ultra on 13.0.10.0 EU Stable

My battery drained 15% in a 8 hour night with this update. I did wipe cache en dalvik. Will see if it does stabilize but not a good sign.

12S Ultra on 13.0.11.0 EU Stable? How is the battery life now, any updates?

12S Ultra on 13.0.11.0 EU Stable? How is the battery life now, any updates?

I am on 13.0.11.0 EU. So far so good. Battery can last till end of day with normal use. Not seeing any exceptionally high drain at this point. I don't game. Just using daily apps and driving apps, videos on YouTube, and social media apps as well

Took the plunge literally 5 mins ago and flashed to 13.0.11.0 EU.
Whatsapp video upload stutter is gone so far!

Testing batt life now to see if there is anything abnormal.

Am on the TWRP that came with 13.0.8.0, i didn't remove screen lock.
I used the Updater app to choose update package which i copied in.
When rebooted, it asked me for screen lock PIN, i entered it and it went to update.
Rebooted after that, all went well!

By the way guys, I tried searching for changelog on the EU rom versions, could find it.

Is there any changelogs available for the EU rom for each version?

I think it's the same change log as miui CN:

• New: Memory extension is available now
• Optimization: System responsiveness
• Optimization: Overall responsiveness and performance
• Optimization: Optimized power consumption so multiple apps running in the background don`t drain battery
• Optimization: Switching between Wi-Fi and mobile data when Wi-Fi connection is weak

Ok cool. I thought EU rom would add a few things here n there sometimes lol

Spoke too soon, the WhatsApp video upload stutter is still there and it seems to be a common issue.
This only happens to 1080p videos, changing my recording to 4k 30p/60p seems to solve the problem.

hopefully someone has a fix!

Anybody having issues flashing this update in twrp?

I always get errors about not being able to mount the /system_root and it exits out twrp.

Use Ota and latest TWRP.

Hi,

I cannot use contactless payment today and got this prompt from google pay: "your phone doesn't meet security requirements". Before that it was working fine.

Did I mess up anything? What can I do to make it work again?

I am on xiaomi.eu 13.0.11
