I need to download the global version of Xiaomi 12S Ultra. Can any one help me?
Are you sure, that global version for this phone exists?
Hello,
My intention is to update my XIAOMI 12S Ultra from the old 13.0.8 stable to the new 14.0.14. and
I have managed to download from internet, from different places, 3 large files :
thor_images_V14.0.14.0.TLACNXM_20230818.0000.00_13.0_cn_8daccfdccd. TGZ file 7.03 GB
xiaomi.eu_multi_THOR_V14.0.14.0.TLACNXM_df60a3e5ff_v14-13.zip MD5file 32bytes
xiaomi.eu_multi_THOR_V14.0.14.0.TLACNXM_df60a3e5ff_v14-13.zip Adobe Acrobat Document 5.03 GB
Are these the right files or jokes? Should I reset to factory settings?
What to do? where to copy them, in what folder to make Update ?
Thank you
Paul
And where did you download it from?
Miui13 rom 13.0.9.0 is soo terrible. It can’t even support google assistant hands free option and unsecure app prompt on app keep prompting for 10 seconds approval.
There’s not surprising, because MIUI 13 is a vwery raw OS.
