Hi guys, I recently replaced the battery of my phone and I also want to upgrade my firware since I have been having problems with internet connection lately.
My current version is:

Android 5.1.1 LMY47V
MIUI: 7.1 by xiaomi.eu stable 7.1.4.0
Twrp 2.8.7.0

Can you please suggest a stable rom without bugs? I was pretty happy with the one I have now, but I still want to upgrade it.
I have read that with the upgrade to Android 7+ the camera has lost sharpness, did they fix that with new versions? Can you please help me with the upgrade, providing a detailed guide? Last time I have played (installing custom roms I mean) with android was 2016 when I bought the xiaomi. Thank you for your help.
 
Hi!!!

Is there a possibility to upgrade the system?
I'm currently on last China dev rom.
I can not unlock bootloader, same meesage every time "Current account cannot unlock this device" for last two month.
I tried with another Mi acount and got the same message.

If someone knows how to solve this, i would be grateful.
 
instala la versión 6.1.7 que viene con el gestor de arranque desbloqueado, le haces rott , despues le metes twrp, y ya puedes instalar la rom eu que quieras y el gestor de arranque se quedara abierto, saludos ,
