Background Info -
I purchased my 16GB x 512GB Mi MIX Fold from a reputable supplier on Alibaba. It was claimed that he was capable of making it have a "Global" ROM (a 5 - 7 day process is how long it took him). All Google services and apps were preloaded, just like my first Xiaomi Global phone I purchased 1.5 years ago. As well as only some of the Xiaomi Global apps. Now that I have the phone, I am running into a fair bit of issues (in this post I am only focusing on one). I did bring these all up to the supplier (of course including updating the ROM issues), all without much help. All he gave me was he said the ROM on my phone is actually the EEA version that was modified, and of I need any updates, go on www.xiaomi.eu. So not much help, because come to find out, they don't support the Mi MIX Fold and that there is no ROMs available. Including the current ROM my phone has right now - V12.0.11.0.RJTCNXM ("Global").

What is nice about my phone is that all the system apps are the Global versions. But what's not so great is the System Apps Updater does not work at all. It shows there are update(s) available for my Global apps, but when I update them, they are indefinitely suck at "Connecting 0%". I also tried Xiaomi's "Get Apps" while switching my Region to "India", it too showed updates, and would not update them no matter what I tried. So, I search online for each individual system app, and update each manually (yes, the whole process is a pain).

So Where I Need Some Help (The Purpose Of This Post...Updating the ROM) -
So, I am in the process of trying to update my phone's ROM, to get the best MIUI has to offer for the Mi MIX Fold. I have searched all over the internet and the only ROMs I can find are "China" versions.

My current ROM version is V12.0.11.0.RJTCNXM ("Global"). I know the most up to date ROM is V12.0.21.0.RJTCNXM (but it's the "China" version). I would like to have the current ROM, but I have a strong feeling that I will loose all functionality of all my Global system apps. The Xiaomi Updater app unfortunately does not work at all. When checking for an update, it says "No updates available". When tapping "Download latest package", it says "Can't download update...Wait a minute or two and try again". When I tap "What's new", it says "You don't have permission to access the update log...". Please see screenshots for all of this. I even tried to update it another traditional Xiaomi way by using Mi PC Suite, which it couldn't even detect my phone when connected. So that doesn't work either.

So my attempts are as follows (at least 20 attempts). I downloaded every Stable Recovery ROM version as listed in the XDA Mi MIX forum titles "MIUI Updates Tracker (Mi MIX Fold)" I also downloaded every ROM version from a couple other sources. I tried to update the ROM (from the newest version to the oldest) using the Xiaomi Updater app through Recovery Mode. Every time it failed saying "Current version is invalid. You can only flash the latest stable ROM", or "Can't verify update...Can't install official ROM". So then I downloaded the ROMs directly from mirror links to Xiaomi's server. I did the same update procedure, they all failed. Does that mean I have to do it via Fastboot?

Last Thoughts -
I included some screenshots showing what the ROM is on my phone (and the outdated Android security update), and what message comes up with each update attempt.

Could you guys point me in the right direction and help me figure out how I can update my Mi MIX Fold to the most current ROM, preferably the EEA version (if possible), since there really is no such thing as a Global version? I would be extremely appreciative if someone can shed some light!

Hi my suggestions is to backup your data firstly from there download the latest fastboot stable of the rom. From there before anything make sure oem unlocked is there inside your phone if not you need to wait 167 hours to fastboot flash the rom. Guides of unlocking is online you can search for that. After that, download the miflash.exe file, that can also be found online and from there flash it with it to the latest Rom . Hope that helps. If you are still unsure , you can always search online of "Flashing with fastboot xiaomi Rom"

Thank you very much for your response!

OK, so it looks like I will have no choice but to get rid of the custom "Global" ROM for the China version. I do wonder though if I am going to lose out on anything as far as the Global system apps (but won't update, unless manually), or all the Google apps & services, or anything else. There of course are many benefits switching to the China ROM.

I'm just a little reluctant because of it being a China ROM being used on a phone in the US. And having features that only work in China and is not optimized for the Global market. As well as features usually found on a Global Xiaomi phone, would be missing or can't work at all. Maybe I am overthinking it all. Another concern is if the China ROM would have English as a language that can be choses. I assume so, but it would be a plus to know 100% before I make the plunge.

Only if I could play around with a Mi MIX Fold with a fresh install of the China ROM. See how different it really is compared to what I currently have. See what it comes with (apps & all) & what is or isn't compatible. My previous, & only Xiaomi phone, was the Global version of the Mi Note 10 Pro. So I have, I guess you can call it, a Xiaomi Global mindset. My Mi MIX Fold is my daily driver, I can't play too much around. Also if I do flash it with China ROM, I can't revert it back to the ROM it has now, since it seems to be custom. Unless I can somehow backup absolute everything, ROM and all.

I know this is a simple question, but what and how is the very best method to back everything up? To not only make sure no data is lost, but also to make the whole process faster when restoring everything.

Do you have any other suggestions or advice? I would appreciate it!
