You need to make sure you flash magisk 17.3 and ONLY that version. Your problem sounds like you have skipped that step, and you certainly didn't note it in the steps you said you did.

Make sure you do that and your phone will boot
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:
i did that also sir, used 17.3 only.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] aleixsr:
Hello,

I followed these steps and I'm in a booting loop, can you help please?

My detailed steps:

- I'm on twrp 3.2.3-8

- Wipe > Advanced Wipe: + Davilk / ART Cache + Cache + System + Data

- Reboot to Recovery again

- Flash from recovery xiaomi.eu_multi_MIMix3_9.3.14_v10-9.zip (I cannot use Chinese rom because I got "Zip Treble compatibility error!")

- Wipe > Advanced Wipe: + Data

- Wipe > Factory Reset

- Reboot to Recovery again

- Flash > Install image > PixelExperienceP-arm64-aonly.img to System Image

- Flash > Magisk-v17.3.mod4mimix3.zip

- Flash > Universal_SafetyNet_Fix-v3-beta1_v17

I got no errors in whole process but I'm on a boot loop. Please help.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
That's cause your using the A gsi not the AB

If you use the zip ROM EU base will work

If you use the GSI China Dev is most of the time needed. Just delete the compatibility zip from the zip then flash

No need for advanced wipe

No need to wipe system

No need for multiple reboots into twrp

No need for modified magisk, just flash normal 17.3

Keep it simple
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] aleixsr:
I tried again:

- I'm on twrp 3.2.3-8

- Wipe > Advanced Wipe: + Davilk / ART Cache + Cache + Data

- Flash from recovery xiaomi.eu_multi_MIMix3_9.3.14_v10-9.zip (I cannot use Chinese rom because I got "Zip Treble compatibility error!")

- Flash > Install image > PixelExperienceP-arm64-ab.zip to

System Image

- Flash > Magisk-v17.3.zip

Same results, boot loop :crying:
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Use the vendor.img from the dev ROM. If you get compatibility issues do what I said last post.

Quick wipe

Format by typing yes

Flash vendor.img from recommended ROM in OP

Flash gsi/zip

Flash magisk 17.3

It's that simple
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] aleixsr:
I just downloaded miui_MIMIX3_9.3.14_a17d32d126_9.0.zip (chinese rom), may be I'm idiot but I cannot see any vendor.img there. ¿?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Extract the contents, is that also the dev ROM as Dev ROM is the best one for vendor

[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Just flash the whole rom if it's the Dev one
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] aleixsr:
I did it may be 30 times...

I just found vendor.img, it is in fastboot rom (perseus_global_images_V10.2.2.0.PEEMIXM_20190228.0000.00_9.0_global_5c0bb91b94.tgz ) not in dev rom. Now I'm going to try with vendor.img

Can you please confirm which file exactly you flash for gsi? Is it a zip or an img file?

thanks!
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
GSI is always an img file
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] laopai:
I had the same problem at booting. e.g. Stucking at the logo. Eventually I found the trick. After flashing the rom and Magisk 17.3, you MUST NOT boot from TWRP. Instead, push the power button for about 10 seconds to power off the phone. And then, power on the phone again. All is good then.

Cheers!

[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] aleixsr:
Sorry it doesn't work for me.

Can please somebody share extact filenames of rom and PE you used to flash? I'm desperate!
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Flash dev rom

Put PE zip on phone

Flash zip

Flash magisk 17.3

Wipe and format (yes)

........

U know... it's an amoled screen...

I just worry about the screen...

Im so excited. I just got the phone like an hour ago. Should i flash this? Is it stable enough?:D
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Yeah, everything works for me
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] paulo boë:
So can you help me with this maybe?

Edit:

Also, how does it work with the slider?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Wait 72 hours

Slider isn't functional

But the camera is? Srry if i sound stupid....
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Camera works fine
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] jericho246:
Camera works well, just install this https://f.celsoazevedo.com/file/gcamera/MGC_6.1.021_MI8_V2e.apk (don't remember if it's included with the ROM, but this is a recent version of GCam that works very well on our Mix 3). Only thing to note though, you can't record videos in 4K 60FPS. That's why I went back to Xiaomi.eu ROM. There's a way to get MIUI cam on PE ROM but it's quite buggy so not sure if it's really worth the trouble. Other than that, if you like stock Android, Pixel Experience P is perfect for you.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] paulo boë:
Thanks you two for responding. I guess i have to wait 3 days till i can unlock, and then ill install PE.

Also, how the roms performance in general? Games, YT.........
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Manages fine
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Party5999:
Can someone send me a backup (TitaniumBackup) of Camera app?

(If you are on AEX it's perfect but I think the Camera app is the same of PE and ArrowOS)
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Azzlan:
Performance is generally good, however be warned if you have a global version of the phone, there are reports that users including me have been experiencing severe memory leak issues and it's possible you might have these too. Essentially the phone slows down until it's unusable after around 24 hours, and you will have no choice but to reboot to fix it and get the phone running properly again

Not saying you'll have these issues, you might be fine, but worth highlighting.

Also, I'd suggest flashing AEX not PE
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Xyam:
Did you mean you flashed PE and encountered memory leak?

By the way where's AEX? didn't see
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Post 23
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Azzlan:
Yes, I tried PE, AEX and Arrow OS. I flashed these using the steps laid out using the correct vendor etc, etc. All roms had the same memory leak issue, they would slow down to a crawl after about a day and would need to be rebooted before the phone was unusable again. This seems to be a global phone version problem only though, so if you have the Chinese version you will be ok
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Xyam:
Thanks for the comments. Why didn't you flash over the Chinese vendor first?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Browns:
He did, but then you'll have the memory leak issue if you've a global phone. I didn't flash the Chinese vendor/rom and flashed the AEX rom directly. I don't have the memory leak issue on my global phone :good:
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] rafik25:
I have a global phone and I use AEX with chinese vendor and not this issue at all.....

Hey guys I followed the instruction mentioned in the OP but could not get my device to boot, I also tried to flash magisk 17.3 but it didn't help. Could anyone please provide a more detailed instructions? Thanks.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] suzook:
After you boot into twrp, try FORMATTING data...Yes, a pita, but after that reboot to twrp, move rom and magisk back to device, flash rom, then magisk, it then should boot.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] paulo boë:
My device also won't boot. It's stuck at mi logo. And rebooting on its own..... Please help
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] laopai:
I had similar problem. Eventually I got it working by the following trick:

Reflash everything in TWRP. Don't reboot or power off from inside TWRP. Instead, push the power button for about 10 seconds to power off the phone. Then reboot.

Now everything is good for me.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] paulo boë:
Srry for asking but what is everything. Can you give us a step by step tutorial? I dont really know what to flash beforehand.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] laopai:
Follow OP's step by step instructions. At the end, just don't reboot or power off the phone from inside TWRP. Instead, using power button to power off the phone. Then reboot.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] paulo boë:
"If you are using Global /China Stable or third party rom (Xiaomi.eu), please download China Developer from here (search for "小米MIX3最新 开发版 线刷Fastboot完整包点击下载") and flash it, then flash PE system.img.

It seems current stable rom has some bugs in vendor or firmware (e.g. Google Camera is laggy)."

Do I have to flash everything in this zip?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] laopai:
To play safe, you should. But I didn't. I flashed PE and Magisk 17.3 over the latest global ROM.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Xyam:
I did. But no luck.

---------- Post added at 01:58 AM ---------- Previous post was at 01:57 AM ----------

I saw this trick last night and I also tried, didn't boot either

---------- Post added at 02:01 AM ---------- Previous post was at 01:58 AM ----------

I did that too, but the latest PE is no longer a system imagine, instead it is a zip. No error was found flashing the PE zip, but it just did not boot.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] paulo boë:
Nope. Im still stuck here.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] james1089:
Flash an earlier EU ROM first, then you should be ok
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] paulo boë:
Can you link it? Cus i dont know where to look
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] homer.ali:
Hey guys had a lot of trouble with these ROMs so just wanted share my experience for those who are also running into trouble.

Coming from global phone running xiaomi.eu weekly the only steps that allowed me to get to boot are as follows:

In twrp: factory reset then format data (hit yes to accept).

Reboot phone and reenter twrp.

Connect to computer and transfer xiaomi.eu rom onto root of device (I suspect any would work but I happen to have used 10.2.2.0.PEECNXM_v10-9 which is believe was xiaomi.eu stable release), pixel experience ROM zip and magisk-v17.3mod4mimix3

Flash the xiaomi.eu rom first then without rebooting or any formatting or factory resetting immediately flash the PE ROM zip and then magisk 17.3.

Once those three files are flashed via twrp go to wipe and the factory reset then format data again.

This last part is very counter intuitive to me but believe it or not, it was what finally got me out of bootloop.

Now of note, with this process I do have the memory leak issue. I understand that some users have stated that I may not if I used a different base ROM first instead of the one I used. However, doing this same process with cn ROMs always led to a boot loop on my device, no matter how I flashed them or which ones.

That being said, I'd like to be able to get to the root cause of the memory leak if it's at all possible.

Boost+ by htc doesn't appear to help but actually demonstrates the problem.

Going to sleep last night the phone had 59% memory usage according to boost +. This morning the phone now shows 79% and climbing. A reboot resets the memory usage back down to 55%.

Furthermore there has definitely been a noticable slowing for me within about 12 hours of reboot regardless of usage. Within 24 hours the phone becomes virtually unusable without a reboot.

Now does anyone know what tool I can use to potentially diagnose this memory leak issue? Most usage analysis tools out there only show that system is using up X amount of ram without any further granularity as to what process or system app is using how much ram.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] fabu01:
thank you so much homer.ali!

After 2 Days and a lot of bootloops.

and now it works.

the last step was the goal -> wipe and then factory reset then format data
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Shouldn't of taken you 2 days lol the instructions are spammed all the way throughout the thread especially with the format data
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] suzook:
LMFAO. Agree.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Party5999:
Lol
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] homer.ali:
Hmm I dunno man let's take it easy..

I had trouble too. There's 89 pages on this thread and tons of instructions that didnt work for me. The ones that did didn't really highlight the specific last step which is very counter intuitive.

And keep in mind that every failed attempt means about an hour of copying files and waiting for things to flash.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] ritchie888:
I appreciate your help. I couldn't get anything to work until I used the same .eu ROM you suggested. The Chinese Fastboot ROM in the OP paired with PE+Magisk 17.3 still caused the boot loop for me. Worth noting that although I did the wipe/factory reset at the beginning, I didn't do it at the end of the process. I followed someone else's advice to not reboot at the end using TWRP and to just hard-restart by holding the power button for 10+ seconds, perhaps that helped me too.

Now, although I have a ROM that boots, I'm having a weird issue that I haven't seen elsewhere in this thread (although admittedly I haven't gone through all 89 pages, just skimmed and tried the search functionality). My phone thinks I'm roaming, and I'm not. I'm in Austria with an Austrian SIM. The stock ROM didn't think I was roaming. I have an 'r' on my network, and it won't connect to mobile internet unless I toggle roaming on. WiFi works fine. So far, that's the only issue I've noticed, but I've barely had it for an hour so I can't speak of the memory leak yet.

Any advice on how to get it back to non-roaming? I tried playing with the APN settings, but it didn't do anything. I'm on a MVNO network provider (bob), if that makes a difference.

Edit: also to add, I have a notification that states: 'Phone Services. Lost mobile data connection. Data roaming is turned off. Tap to turn on.'

Edit: Everything above can be ignored. I'm new to Austria and have never heard of national roaming before, which seems to be when an MVNO has different network parameters to its parent company, and can be viewed as roaming, even though you're in the country of use. After a lot of searching I solved my issue, using a great EdXposed module called 'Roaming Control'. I can give detailed instructions on how to get this working if anyone is interested and having issues, drop me a PM.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] ngpnamblc:
is this rom still being updated or is it discontinued?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
Discontinued I think, everything works anyway. Just the security patches that are outdated now
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Williammmm:
And the notification led that blink like crazy fast, and battery life that is 25% worse, and ram memory issue
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
I've not got any of these.

I'm assuming you're on a global device as that seems to be what the issues have in common
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Browns:
I'm running AEX and everything works well. I'm only having an audio issue when I use my phone with android auto in my car. Every 6 minutes or so I've a very quick skip. Like someone is pressing the pause and play button very quick after each other... I was wondering if other people who are using Android auto have the same issue or not with PE or AEX...

[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:
after installing xiaomi rom+pixel rom+magisk what did you do exactly ?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Mackay53:
That will dpend on how you use your phone
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Xyam:
Exactly.

But the standby time is worse than MIUI. AOD and LED indicators are too bright, which may consume little bit more power.

---------- Post added at 09:49 AM ---------- Previous post was at 09:43 AM ----------

For me I installed AEX, not PE.

My steps are:

1. Factory reset

2. Format data

3. Reboot to twrp

However after doing step 3 I found my internal storage was messed up, so I formatted SD card:

4. Format SD card (i.e. internal storage)

5. Transfer everything you need to the internal storage

6. Add xiaomi.eu, AEX and magisk to the flash queue

7. Factory reset

8. Format data

9. Reboot

After entering to AEX it will take less than 3mins to complete the first boot, if it takes you more than 5mins for the first boot that means you've got problems.

[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:
Thanks, just one last question, what do you mean by factory reset (does it means wipe cache, dalvik and data ?)? sorry it is a dumb question but i am confused. And thanks for all the instructions.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Xyam:
Go to twrp

1. click wipe

2. Swipe to factory reset

3. click format data

4. Type "yes" in the text box

5. Click OK

Done!
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:

To be fair, it's not ALL spam, there's a lot of moaning as well.

---------- Post added at 09:51 AM ---------- Previous post was at 09:47 AM ----------

Factory Reset refers to the process of wiping the /data partition. This erases all the settings and all the user apps. The Dalvik/Art cache & data cache can be wiped separately from this and are rebuilt during the boot process and when things start running.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:
tRied everything as you guys said. Followed every step from format to magisk and formatting data. still sometimes getting bootloops and sometimes getting stuck at boot screen.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] invisiblewave:
Double check that you're flashing the correct vendor image and the correct version of Magisk.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:
vendor image from mi mix 3 chinese version and tried magisk both versions 17.3 and 19 also. still result same sir.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] invisiblewave:
By "double check", I mean go back and check your source documentation and download, maybe look for an alternative download source, and flash again using the new one. It is known that if you download the correct images, and follow the instructions, your phone will boot, therefore you're either flashing the wrong things, or you're not following the steps correctly.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Xyam:
Don't use Chinese version, use xiaomi.eu, either stable or weekly will do
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:
tried with weekly version, now phone boots, show mi logo then it restarts and gets stuck there forever.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Xyam:
Did you perform factory reset and format data at the end?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] dheerajverma143:
yes i did sir. Is there something wrong with my device ? can anybody make a short video of how to do it ? because i am preety sure that i did everything as u mentioned.
