Good day all,

Today, I decided to try install the Unofficial PE Rom witch can be found here (https://treble.andro.plus/pe.html)
I Followed these instructions (https://www.getdroidtips.com/pixel-experience-rom-xiaomi-mi-mix-3/)
For some reason i decided to do a full wipe ie. ;
Dalvik/ART Cache
Data
Internal Storage
Cache
System
I went to install PE ROM and upon completion, i was boot-looping and rebooting into TWRP Recovery 3.2.3-1205 for MIX 3 --by wzsx150.
In a panic, i tried reinstalling the weekly ROM again by doing the same steps above, and behold i am still getting the same problem.
Would someone please help me out here as for this is my only phone and need to get it back up and running.
Thanks in advance.

Going from one rom to another requires you to remove encryption so format data

1. Flash the China dev vendor.img, or the full China Dev ROM, or Xiaomi EU (works ok with PE)
2. Install PE zip
3. Quick Wipe and format 'yes' in twrp
4. Flash Magisk
That's how I do it for all ROMs and GSI and works fine.
You'll get the China dev vendor IMG from the link on post one of the PE thread. You can flash it with twrp.
Always recommend to use the vendor IMG from China Dev instead of EU, especially with the GSI ROMs.

are you on global?
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 always works for me
thanks to @homer.ali

Works for the Mi Mix 3 coming from MIUI 11 EU

Thank you so much for these instructions. Coming from Global MIUI 11, I tried to figure out how to install PE for the last 2 days and every time I ended up being stuck in a bootloop. So far, I tried to install Resurrection Remix, Lineage OS and Evolution X without success.
Your instructions solved this issue. BTW: the only working version of TWRP for me was twrp-3.2.3-8-perseus-mauronofrio. After flashing this version, I was able to install the latest TWRP.
this always works for me

Do you (or anyone else in this thread) know whether these steps [install order: xiaomi.eu, rom, magisk | then: factory reset + wipe data] work for other custom roms on the Mi Mix 3 as well? >> Short answer: no. Tried it for the above roms. I always end up in TWRP (or bootloop) after flashing either way (the official or the on I 've tried here).

@chromanju did you solve this problem?

Can't install custom ROMs. Help!!!

Few days earlier I had to use MSM tool as my OP6 only went to Crash Dump mode everytime.
So after flashing the tool, everything went back to normal, but since then I can't get any custom ROM to install on my phone. whenever I do flash the rom and then twrp, I reboot to recovery for flashing gapps, it takes me to fastboot mode instead and never boots.
Evidently, I have installed Omni, Havoc and all the other roms before. What can the problem be? Any help please?
I supposed you read the instructions and flashed to both slots? Or did you do like most and skip a few steps?
Hi!
I am in the same situation : MSM tool and then I can no longer install custom rom. Have you resolved the problem ?
Thanks !

Did you flash oos to both slots? Like the comment above yours tells him to.
People need to read. This already been discussed over and over.
I didn't understand in the previous post that it is OOS that need to be flash twice, not the custom rom. Thanks whizeguy !
The OP6 is my first device with this A / B. I read a lot about this A / B and I think I understand it. But I'm going to install this ROM https://forum.xda-developers.com/o...eally so stupid? Can some one help me please?

If i boot in to twrp, flash the rom and twrp, go to reboot -> recovery: the screen stays black and does not reboot in to recovery.
I tried twrp-3.2.3-1-enchilada and twrp-3.2.3-x_blu_spark_v9.86_op6
After hours of trying, the phone booted one time the new rom. Now i'm back on the stock rom, because OP of the ROM listed features which are not included.

How to perform a clean install?

How to do a clean install(no rom installed just recovery)? I want to format everything and flash my rom thru otg. Shud I wipe everything when I boot to recovery?
I think internal storage is the correct option then though it also removes all media on the device. Otherwise clear system, data, cache, bootloader, dalvik. Then install the rom from external source.
Should I flash from fastboot the recovery(twrp)? It might get wiped once the wipe everything.
I have same doubts....

Flashing this phone looks like sorcery....
Miss all days we could go to TWRP, erase all **** and then just flash rom. Period.
Now, doing this can even brick the dam phone.
It sucks!
EDIT*
Did Nuke 9.0.5 and install fresh 9.0.3.:angel:

That also happened to me. I do not know how to go to another custom ROM from another custom ROM without going to MsmDownloadToolV4 to unbrick my device. Actually i did unbrick my device twice already because of trying various custom ROM.
Also, is there a way to just restore from recovery then flash another custom ROM. Then if we want to change custom ROM again we can just restore from recovery again then flash another custom ROM?
Please help us guys. Thanks.

Can't install Lineage OS properly; device freezes and reboots after startup

Hi people,
I've been struggling with this for the past 2 days and I'm trying really hard not to give up
I downloaded the stable rom from the MIUI website (for Mi Note 3 aka jason), installed it successfully via MiFlash, and tried flashing Lineage after I did a factory + data + system + cache wipe. It ended with me getting the dreaded error 7.
A bit later, I realized I had to get the dev build from the MIUI website and flash it before flashing Lineage OS. So I did - I updated to MIUI 10 using the dev build, made sure it was working and tried flashing Lineage OS on top of it (after wiping the partitions I mentioned earlier, following the Lineage OS instructions).
So eventually I got it to work - sort of.
Lineage OS is booting properly, but the device freezes before it can find any wifi networks to connect to (and then reboots), and that's why I think the culprit is the modem.
So, a few questions -
1. did it happen to anyone else? I searched endlessly but came up with nothing
2. If it is a modem issue - where can I find a working one? I looked it up and found nothing
3. If it isn't a modem issue - what should I do?
If I'm doing anything wrong - please tell me. I'm flashing custom roms since 2011 and this is the first time something like this has happened to me.
Thanks for all your help!
Hi, first of all you need an unencrypted phone - Format data in TWRP (3.2.3.1), then wipe system, data, cache, dalvik. Flash the Miui 10 china stable firmware 10.0.2 or 10.0.4, then rom, gapps and reboot.
Good luck, zaqm

twrp bootloop

Hi,
after pitchblack test I have softbriqued my poco.
I used miflash pro for reinstall and everything was good.
but, after unlock again my phone, flash the recovery, (everything was good at this time) flash my rom, the rom doesn't want to boot.
I tried many rom , change the twrp, nothing.
If anaybody have a solution for this issue, you're welcome.
Thanks a lot.
may be flash again with MIFLASH(clean all ) and go to the end of the configuration and check if everything is good .
https://xiaomiflashtool.com/
have you done...
format data in TWRP after flash TWRP and before install ROM again?
best TWRP for me...
recovery-TWRP-3.4.2B-0623-REDMI_K30PRO-CN-wzsx150
start twrp, only via fastboot with my rom version xiaomi.eu_multi_HMK30Pro_20.10.16_v12-11
Thanks for your response.
I've got a first issue with miflash, but the second time was good.
I don't know why it was impossible to connect with fastboot! That's the game of flashing..
I forgot one thing during my flashing session.. : after unlock my bootloader, and reflash a new rom, I didn't set pattern password...... It was the issue!
edit: after miflash session I could repare my phone to stock global. But after this I want to change my rom, and the twrp bootloop became.really strange.
This morning I use miflashtools another time and I keep this version of miui.
I don't know why it impossible to reinstall another rom after complete miflafh process!
Always and always back in recovery, each time!

Twrp used: all! China twrp 0328, and maunofrio
Install rom: format data, always, reboot to recovery, always, flash, succeed, done.
Wipe cache dalvik.
Reboot, and it became to twrp.
With my Poco, I flashed maybe 30 or 40 times for test some roms.
But since I tested pitch-black twrp everything gone wrong!

So you must flash miui V12.0.3.0.QJKMIXM with miflash. (no need to configure it just restart in fasboot and install trwp chinesse)
format data(if red lignes reboot twrp format again)->reboot twrp flash MMX rom, format data->reboot system
(do not use WIPE).

That's what I did!
I'm on stock 12.0.3.0 now, with maunofrio twrp. I tested with chinese to.
I can root the rom, use magisk as well.
I did may be, 3 or 4 miflash for flash stock rom.,and always the same issue.
When I flash I haven't any issues with redlines, everything gone fine.
With stock its OK, with custom not.

It's just incredible and I don't understand why I need to format data after install now!
One month ago, wipe cache dalvik was enough to launch boot!

OSS Vendor + A11, how to switch? - POCO x3

Hi,
So i have been on arrow os for maybe 6 months now, i wanted to update to the latest build but it told me that i had to factory reset the phone to do so, so i thought lets try some other rom on the way, i flashed the pixel experience rom, then switched to the latest build of Arrow os.
Now since i am on arrow os OSS Vendor A11, i wanted to move back to pixel experience, i tried flashing it but it would not. I flashed evolution X and rebooted the system but i was back in recovery (bootloop), i cleaned data and flashed pixel experience (successfully this time) but i was again greeted by a bootloop.
I flashed arrow os back and it turned on the device into arrow os. How can i switch to any other non OSS rom? Is it possible without adb protocol or mi flash tool? What would be the way to do so?
Thanks
Download and flash any full MIUI recovery ROM. They include stock vendor and firmware.
Some custom ROMs require A10 firmware+vendor, some others need A11, so pick accordingly.
perform format data if you're encrypted, reboot to recovery, then flash any ROM of your choice.

Thanks for your answer. Last night i flashed dots rom on my phone after format data and my phone went into a bootloop and i was unable to flash back arrow os because recovery would say "unable to mount system/root" and 2 more errors like this. Anyways it took me like an hour to flash arrow back and boot up.
Can you give me link to the MIUI recovery rom?

Of course, here you go:

The ultimate script that provides firmware packages for Xiaomi devices.

I had the same issue back then (system mount error), I also have no idea what caused it.
Good luck!

Check your ROM requirements, for different ROMs need different firmware versions(see "Android" column on the website)
Usually the required firmware is written in the ROM description.
If you're not sure, you can always ask the ROM developer.
For the dot-OS ROM you are about to flash, I think it needs A10 firmware. CMIIW
