Guide: Reverse-engineering Xiaomi OTA Updates to Find Unreleased Versions

This is something I've been looking into in order to find newer, older, and unreleased updates for the Mi Mix 2.
Ideally, I'd like to figure out a way to get Xiaomi's nightly builds, which go out to only beta testers. I think I'm close, but any help I can get would be awesome.
I currently have two methods. One of them is rather difficult, the other is rather easy. Let's start with the easy one.
Method 1: Example 1
http://update.miui.com/updates/mi-updateV6.php?v=MIUI-7.9.21&c=7.1&d=chiron_global&b=X
This is a URL which asks for an update to the unreleased MIUI 9 7.9.21 global edition.
If you visit this URL, you get the following response:
Code:
{"UserLevel":9,"LatestVersion":{"type":"rom","device":"chiron_global","name":"XM-MIMIX2-GLOBAL 7.9.21","description":"MIUI\u5347\u7ea7","descriptionUrl":"http:\/\/update.miui.com\/updates\/updateinfo\/7.9.21\/chiron_global_0_7.9.21_4494ccfcc506caca9904efb74b489e0a.html","md5":"7f94ca393fae77c6171e6c7a551bea2e","filename":"miui_MIMIX2Global_7.9.21_7f94ca393f_7.1.zip","filesize":"1.6G","codebase":"7.1","version":"7.9.21","branch":"X"},"UpdateList":[{"type":"rom","device":"chiron_global","name":"XM-MIMIX2-GLOBAL 7.9.21","description":"","descriptionUrl":"http:\/\/update.miui.com\/updates\/updateinfo\/7.9.21\/chiron_global_0_7.9.21_4494ccfcc506caca9904efb74b489e0a.html","md5":"7f94ca393fae77c6171e6c7a551bea2e","filename":"miui_MIMIX2Global_7.9.21_7f94ca393f_7.1.zip","filesize":"1.6G","codebase":"7.1","version":"7.9.21","branch":"X"}],"IncrementalUpdateList":[],"MirrorList":["http:\/\/bigota.d.miui.com"],"Signup":{"version":"","total":"","rank":""},"AuthResult":0,"ForceUpdate":0
We can piece together looking at this that the update file can be downloaded at:
http://bigota.d.miui.com/7.9.21/miui_MIMIX2Global_7.9.21_7f94ca393f_7.1.zip
Method 1 Example 2
It was announced today that there was a new Chinese stable release pushed only to some phones called 8.5.7.0.NDECNEF. We can modify the parameters in the URL to get this:
http://update.miui.com/updates/mi-updateV6.php?v=MIUI-V8.5.7.0.NDECNEF&c=7.1&d=chiron&b=S
This returns the following:
Code:
{"UserLevel":9,"LatestVersion":[],"UpdateList":[{"type":"rom","device":"chiron","name":"XM-MIMIX2 V8.5.7.0.NDECNEF","description":"","descriptionUrl":"http:\/\/update.miui.com\/updates\/updateinfo\/V8.5.7.0.NDECNEF\/chiron_0_V8.5.7.0.NDECNEF_a9374e7e6aa4f38a22fd58aae29337ce.html","md5":"487f34ee14e84d0eb9ed280a059bcc65","filename":"miui_MIMIX2_V8.5.7.0.NDECNEF_487f34ee14_7.1.zip","filesize":"1.4G","codebase":"7.1","version":"V8.5.7.0.NDECNEF","branch":"F"}],"IncrementalUpdateList":[],"MirrorList":["http:\/\/bigota.d.miui.com"],"Signup":{"version":"","total":"","rank":""},"AuthResult":0,"ForceUpdate":0}
And that lets us know that the update can be found at:
http://bigota.d.miui.com/V8.5.7.0.NDECNEF/miui_MIMIX2_V8.5.7.0.NDECNEF_487f34ee14_7.1.zip
So now that we see that we have a way to query for downloads, let's look into some of the parameters.
At a minimum we need the following:
v=MIUI-V8.5.7.0.NDECNEF - This is the version with which you are querying.
c=7.1 - This is the build of Andoid. It's Android 7.1 so we put 7.1
d=chiron - This is the device. For Chinese Mix 2 firmwares it's chiron. For global it's chiron_global
You might also notice this:
b=S - S means stable. X means weekly. Actually, there is a whole list as follows, but not sure how accurate it is:
Code:
«S» — monthly build
«X» — weekly build
«D» — daily build
«E» — emegency build
«F» — stable build
«A» — experimental build
«I» — internal build
«T» — top secret build
«U» — unstable build
On top of this, there are more possible parameters. I will get around to these when talking about Method 2.
Right now, I can't access anything but weekly and stable builds, so there are not really any undiscovered/unannounced/internal builds that I've been able to find. But I think we are on the right track to being able to find them. I'm hoping that other people can continue looking using this information, and we'll see if we can find anything. Stay tuned while I update this post with Method 2, which is much more complex and much more likely to yield results.

Isn't this link (http://bigota.d.miui.com/7.9.21/miui_MIMIX2Global_7.9.21_7f94ca393f_7.1.zip) global miui 9?
I say because Chinese dev rom (miui 9) is the same miui version (7.9.19 which is a lower firmware number)

This is my first miui device, using miflash, I cant select the .zip file as it's not a fastboot image.
How did you manage to flash the .zip with fastboot flashing ?

I used sdat2img.py to convert the system data to something flashable. Then I looked up which partitions need to be flashed where by checking a flash-all.bat file, and followed that format using fastboot to flash each partition.
But... there's no reason to flash this. It's not a public release and it doesn't really do anything better than other choices. I think flashing xiaomi.eu is a better choice.

I was able to find the first MIUI 9 Stable (non-developer) global build for Mix 2.

Caveat is, I think it's actually older than the most recent developer build.

The global dev builds will always be newer and include the most recent bug fixes and security patches, so that's no surprise the stable was built before any of the recent developer ROMs.

11.0.3.0 Mi9T Pro OTA update

Does anyone else received this update on the Mi9T Pro? I have an EEA version and the update just popped up today. It looks like the update to Android 10 and miui 11 in one go. Just wanted to know if anyone else installed this. The current version is good enough for me now not keen on the update, specially if it brings bugs.

Yes, me too, going to install it later today, when I'm off work, make sure you do a full twrp backup first.

Yes, I saw on a facebook group that some EU users already got it. But no feedbacks yet.
Still no OTA for global the version.
Here is the link for the EEA update.

Just got it too. Will install shortly.

i've updated it. How can i disable vibration after i kill app from recents?

Installed and rooted via patched image a few hours ago and everything is working smoothly. The setting menu is much more streamlined and the fingerprint scanner works much better now! I haven't installed TWRP since I don't know which version works, maybe someone here can share which version works for them.

Can install this on Global Rom (Bootloader locked)?

Wait for the official Global update. Flashing different versions can seriously mess up your phone.

Guys, i'm on MIUI Global 10.3.3.0 (Stable) right now with an unlocked Bootloader & root (twrp & Magisk).
When the MIUI 11 update arrives (Germany), can i just OTA update or do i have to do something specific?
Excuse my bad english, lol.

And this is why people get "hacked" and their data stolen.
Update your device, especially if it comes from official channels!
I understand that you are a little reluctant to install it, but rest assured, I have been a beta tester for miui 11 for this device, they have squashed lots of bugs.

Downloaded and installed ?

First I would like to thank you your comment and advice. I was planning to upgrade but not just yet. However I don't think you would have to be that drastic and your comment may also scare others.(don't have to be a scaremonger) No one will hack my device or steal my data just because I wait on an update?!!
I have already tested miui11 on my prev k20pro and I found lots of bugs. I know this is an official update, but we all know this can still be full of bugs. I do like xiaomi (otherwise I wouldn't buy the mi9t pro) specially because they provide frequent updates. However this isn't my first xiaomi device and taking my previous experience with buggy updates I just wanted to be extra careful before rolling out the update, mainly because my BL is locked and couldn't flash the downgrade immediately if I find the new version unusable.
Luckily others already provided positive feedbacks so I'm sure I will do the update shortly.

Does it really have a battery drain issue? I am very hesitant to update it because the current version is giving me a very good SOT.

based on my exp, if you using twrp you must clean (wipe system and data) install the miui 11 zip file because miui 10 and miui 11 are different android based. will be much problem if you just flash the zip file without wipe the data partition.

If you change ROM branch ( move from your Xiaomi EU version to any other, EEA, Global, Stock Chinese etc etc) you MUST format data after flashing or you may find you get stuck in a boot loop until you do. This is due to possible partition differences between the ROM branches.

Don't forget, first boot on any new ROM will take ages, so as long as you see the boot logo, just wait. Don't be tempted to stop or reboot, just sit back and wait

It's really a bad idea :
- A lot of Official Xiaomi Mi 11 tester have encounter EDL mode / Full Brick by flashing OTA ROM
- Actual TWRP is NOT compatible with A12... (and it's the only way you can flash your link because we don't have the fastboot version)
So before share this, try yourself but you are warned... be careful !

hello, from more than android 11 to android 12 the change will not even be seen I think due to the miui overlay.

It's really a bad idea :
- A lot of Official Xiaomi Mi 11 tester have encounter EDL mode / Full Brick by flashing OTA ROM
- Actual TWRP is NOT compatible with A12... (and it's the only way you can flash your link because we don't have the fastboot version)
So before share this, try yourself but you are warned... be careful !

Oh yes! I can confirm this very much. I got into EDL and couldn't solve it myself. Finally I paid telegram guy to unbrick/reflash and solve it. So I would NOT recommend anyone (who is not super expert in to flashing a/b partition and all) to try it using recovery-twrp flash.

Read carefully this thread, could brick phone!!!!!

This is true. I bricked MI 11 twice.
What is curious is that MIUI 12.5.1.0 (android 12), is in the firmware library of MI and is for recovery

Not if you have a full brick (Black screen). Only if you are on EDL mode.
So you can really Brick your device, it can be expensive to just install a MIUI A12 with lags & many bugs.
I advise all to wait on A11 for the moment.

I just learned how to use adb commands and I found out that it can be used to disable some overlays. So, is it possible to disable every miui overlay?

Good evening unfortunately no we can not remove all the overlay to do it we must install an alternative rom (custom).
