Reinstal·lant MIUI oficial d'Android 12 en un smartphone Redmi Note 9S / Curtana

Després d'haver fet provatures diverses amb l'Ubuntu Touch al Xiaomi Redmi 9S, vull tornar a instal·lar l'Android perquè aquest dispositiu no està suporat per a Ubuntu Touch.

Anem a baixar la ROM correcta per a tenir un MIUI oficial amb Android 12. Necessitaré descarregar una Fastboot ROM per curtana, el model del meu smartphone Xiaomi Redmi 9S és el M2003J6A1G (ho sé perquè està escrit en la tapa de darrere de l'smartphone en lletres xicotetes serigrafiades sota la tapa).

He cercat "Redmi Note 9S curtana fastboot ROM MIUI Global” i m'ha dut a la url https://xiaomirom.com/en/rom/redmi-note-9s-redmi-note-9-pro-curtana-glo…

Eixa pàgina em du ací a la pàgina des d'on descarregue directament la versió Download Redmi Note 9S / Note 9 Pro / Note 10 Lite (curtana) V14.0.4.0.SJWMIXM MIUI 14 Stable Full Rom de l'Android 12 https://xiaomirom.com/en/download/redmi-note-9s-note-9-pro-note-10-lite…

He descarregat el fitxer curtana_global_images_V14.0.4.0.SJWMIXM_20230516.0000.00_12.0_global_72c4e6fac8.tgz:

I ara el descromprimirem fent el següent:
