My advice is:Thanks ! I ordered one for myself, let's see when it arrives.
Planning to replace battery at the same time and make my backcover transparent.
Also not sure about which ROM to use, currently on global MIUI with locked bootloader, don't feel like using xiaomi.eu since the security patch is outdated ( global just got an update )
Probably I will have to use a non MIUI rom since Xiaomi is abandoning this phone but I need a super stable and reliable one
The latest stable xiaomi.eu is fine, everything working smoothly. I expect MIUI14 on the phone this year and i want to try it out and stay on that till the lmi become an EOL model. But if you want to try out a custom rom, SparkOS seems to be the best choice.
PS.: Can you please post a photo with the transparent cover when it's done? I'm not sure the how ugly would be if you see the glue that keep it in place
Also: can you send a link for the battery? Mine is still good, but maybe i'll order one just in case,
