Hello Everyone,

On daily bases I see a lot of users struggling hard to flash on their phone official MIUI ROM - China or Global from unofficial/fake ROM for devices with locked bootloader.
Flashing official ROM from Fake ROM on locked bootloader can be complicated task.
This thread were made to gather all the known solutions we have today in one place and to help everyone to flash the official ROM on their device in the easiest way possible - So let's get started.

I used two tutorials that our Moderator invested time to write them so I would like to thank him first - @mitch002



How to flash official ROM on device that running fake/reseller ROM:

How can you know if you are running fake/reseller ROM - Sadly there is no one simple answer for that, but there are simple indications:
  • Official Stable ROM will have always 4 digits and official Developers (Beta) ROM will always have 3 digits.
For example Stable ROM will use 7.5.2.0 but never 7.5.2.0.0 and Developers (Beta) ROM will use 6.5.30 but never 6.5.30.0
Here you have an example of fake ROM:
165231m39f78k449zdyu9c.png

  • Another indication you can see it's when you ROM version stating "Global" but the version code is actually China. For example as you can see in the screen shot above "MIUI Global 7.3 | Stable 7.3.4.0.0 MAACNDE - The word Global with the combination of "CN" impossible as CN is shortcut for China.
  • There are more indications - But those two should be enough for most cases.


So how to flash official ROM from fake ROM:

  • This is probably the most complex solution as there is really no magic solution here. So I will suggest different ways that worked in different situation - Please follow one by one and find the one that working for you.


Option One:


Try the updater App - Some of you will immediately say "this is fake ROM the updater app will not work". Well from you are right it's not working most of the times but there are cases when people manage to update fake ROM to official ROM using only the updater app.
In order to try this method go here: http://en.miui.com/download-299.html#435 download the ROM you want copy it to your phone, launch the updater app, click on the "..." button and click on "Choose update package", then choose the file you copied. Try all 4 ROM's before moving to the next method (Global/China Dev & Stable).

Option Two:

You tried the updater options and nothing worked, so the next step will be to try the Mi PC Suite method - again this method working sometimes and sometimes not. Probably because some windows/drivers issues. My suggestion is if the first step didn't work try this method again and again with different computers and different USB connections.
The reason I'm pushing you to try this method so many times is because this method is 100% safe and not complicated - if this one failed you will have to go to more complicated methods.

You can find very good tutorial on the next link (Big thanks to the creator of the thread (@mitch002 )
http://en.miui.com/thread-309629-1-1.html

Option Three:

If the first two methods didn't work, well here it will be a bit more complicated, since there is only two more methods left.
This step is also 100% safe but require from you to buy special cable in order to flash your phone with official ROM (Second method from the link below).
*** Please note you can also try to unlock your bootloader from fake ROM, it could work because the fake ROM's are based on China ROM version (First method from them link below).

You can find very good tutorial on the next link (Big thanks to the creator of the thread @mitch002)
http://en.miui.com/thread-299790-1-1.html

Option Four - This method is not safe, use it only as last option and on your own responsibility.

Two things you need to know:
  • This method can brick your phone! Simple mistake, wrong drivers installed on your computer and your phone is bricked.
  • Please note that the new MIUI versions (7.3.X.X and above) today already blocking this method (EDL), but if you have the old version you can use it.
This method is here only in order to make this guide complete, just to make it clear I'm not recommending using this method!
This method using "download' mode of the device (some kind of emergency mode) and by this you are actually bypassing the locked bootloader in order to flash the ROM - The name of this mode is "EDL mode".
ForYou decide to use this method search the forum and find a guide by yourself.

Hope This guide will help other members of this forum.

You are right, but this is not the only reason. With locked bootloader if someone steals your phone ...

I'm sorry, but I'm with Portlandbear on this 100%. Xiaomi shafted its users big time.

Not only did they allow resellers to flash our phones (prior to 7.3.x), but it hasn't done anything to help consumers stuck with affected phones. Zero. Nothing. Nada.

Mi suite doesn't even support Android 6.0, yet you've already got loads of devices running 6.0 in the wild. I had a similar issue with my old Mi4c - the suite just wouldn't work with it for months. Xiaomi was shipping phones that could not be recognized by its own software? And now it's doing it again?! That's a great way of losing customers.

Over the past couple of years, I recommended Xiaomi devices to loads of people, more than a dozen of my friends and family use them. Can I recommend them now? Of course not, because chances are they will be stuck with faulty ROMs which they can't replace (at least not on their own - and guess who they'll bug once they figure it out?)

And no, you don't get to use security as an argument or cop-out. These "fake" ROMs do not receive updates, and some of them ship with malware. We are talking about hundreds of thousands, or probably millions of compromised devices that will be inherently unsafe. You think users will be safer with pre-installed malware and no updates, on the off chance someone could steal their phone? Seriously!?

Late last year, I flashed a Mi4c and a Redmi Note 2 while having coffee with my brother. Now it looks like I'll need a week or two to sort out my own phone: apply for the unlock, then wait, and then hope it will work (although I doubt Mi Suite will be ready by then).

It's a shame because I really enjoy Xiaomi phones (and other devices!), but if you keep treating your consumers like this, I'll be the first to jump ship and get a OnePlus or ZUK. Why would I stick with a brand that's intentionally undermining the security of their users? Because that's what you are doing by keeping affected devices locked and asking us to jump through a bunch of hoops to get an official ROM. How many people will brick their phones in the process? How many will become frustrated and ditch Xiaomi?

I just hope you sacked the genius who thought this would be such a great idea. If you did, let us know - just so I can make sure my company doesn't accidentally hire them, because they've got no place in tech.

I think this is why they keep losing market share..
I read yesterday that Xiaomi market share down to Nr. 5 after Oppo, Vivo, Huawei and Apple in 2016!
Yes, it can still be called a flagship killer, since its specs are on par with other famous brand with less price to pay. But the development on software side are just insanely out of track :(...

Hi,

Just buy the DIY cable (if your phone running snapdragon) and it's the fastest and easiest solution.

Thx. Where Can we Buy These Special cables?

How is giving the reseller this Money? Xiaomi ?

Hi,

For the cable try searching by yourself "Deep flashing cable" - You can find it if you want.
About the money for installing fake ROM's are you seriously asking if Xiaomi is giving money to shops for installing fake ROM? Is it sounds logical for you that Xiaomi wants people get fake ROM's full of advertisements spywares? The people that developing those fakes ROM's are paying the money for the installation.

Great Post!!!

Little help needed here. I have Redmi 3 Pro, which i suspect pre-instelled with Fake ROM. I'd like to use Official ROM, but it seems Redmi 3 Pro is not listed. They just show Redmi 3 and Redmi 3S/X. Which ROM should i use?!

Thanks in advance.
