[ROM][perseus][13] LineageOS 20.0 [UNOFFICIAL]

[Mr_A_Warner]

LineageOS is a free, community built, aftermarket firmware distribution of Android 13, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the changelog for a full list of changes & features.

Hi there!
I just installed this ROM without GApps and it seems to get stuck in a bootloop for me.
It's only showing the MIX logo, turning off and then showing the logo again but never booting into LineageOS
I flashed firmware V12.0.3.0.QEECNXM first then fully wiped the device and finally flashed the ROM not sure if I did something wrong since your LineageOS 19.1 is working fine for me

Szia!
Most telepítettem ezt a ROM-ot GApps nélkül, és úgy tűnik, hogy beragadt egy rendszerindítási ciklusba.
Csak a MIX logót mutatja, kikapcsol, majd újra megjelenik, de nem indul el a LineageOS
Először felvillantottam a V12.0.3.0.QEECNXM firmware-t, majd teljesen töröltem az eszközt, végül felvillantottam a ROM-ot, és nem tudtam, hogy valamit rosszul csináltam-e, mivel a LineageOS 19.1 jól működik nekem

Szia!
Én ugyanígy jártam. A telepítéssel minden ok, a firmware rossz. Várom a javított verziót...

Hello !

Same thing for me, boot loop on MIX logo with this ROM, while flashing your 19.1 just after works like a charm.

Tried with firmware 12.0.3 and 12.5.1, same results.

Bootloop in MIX Logo...

this Room Not Working yet

[Dj_Vreditel]

The same for me with Clean flash, bootloop.

Big thanks to Nguyên Thịnh from the Mi Mix 3 Community TG Channel.
Now it works for me.

After installation ROM and GAPPS (optional), you need to flash DFE (file attached), it will disable Force Encryption and you won't see bootloop anymore.

Install twrp, full wipe, format data, flash rom, flash gapp (if you need) and flash dfe and reboot system

 

[hungarick]

Nagy köszönet Nguyên Thịnh -nek a Mi Mix 3 közösségi TG csatornától .
Most már működik nekem.

A ROM és a GAPPS (opcionális) telepítése után meg kell flashelni a DFE-t (fájl csatolva), ez letiltja a Force Encryption funkciót, és többé nem fog megjelenni a bootloop.

Kipróbáltam, így már működik!
Köszönöm a munkát!!!

Hello All
OS working no problem, but Wifi Calling is not working on airplane mode.

 

[Mr_A_Warner]

Apologies to everyone! Seems there is an issue with encryption in the initial build, so DFE is a requirement but I didn't catch this in development as I always flash DFE out of habit. So sorry again for that. I'm hoping to release an update with encryption fixed and no longer causes a bootloop issue

 

[Mr_A_Warner]

New update is out! Now longer requiring DFE to boot!

 

[ducatisto]

New update is out! Now longer requiring DFE to boot!

Didn't work that way for me...updated but got a bootloop until flashing DFE.

 

[aner0]

Hello, how do I update to MIUI 12.0.3.0.QEECNXM? With TWRP recovery?

 

[mashiro_mikage]

New update is out! Now longer requiring DFE to boot!

Very Good. Work Fine in my mi mix 3.

 

[aner0]

Awesome rom, thank you!

 

[Mr_A_Warner]

Didn't work that way for me...updated but got a bootloop until flashing DFE.

You obviously didn't read the update instructions. If you used DFE for the last build, you'll always have to use DFE. It's only Clean flash that you don't need DFE

Sorry... you're right. Just didn't think of it as an update, more of a correction.
