Works fine, but one problem:

Wifi networks with WPA3 (and mixed with WPA2) don't work. I know, there is an issue with WPA3 and tge Note 9. But in MIUI 12.5 firmware I can manualy add a WLAN-network and set security to WPA2 - then the device connect s to the network and set the security parameter hard to WPA2.
In crDroid (and Pixel too) the Wifi-Manager always set the security to WPA2/WPA3-mixed mode automaticaly, even I choose only WPA2 in manualy add.

Is there an aviability to insert the same workflow like in the original firmware? Or is anywhere an opportunity to hard change the security layer to WPA2 for a saved connection? I couldn't find any magisk-modules or apps in f-droid or appstore.

Thx a lot for your great work!

Hi all,

first of all, thank you to Evan_Ferrao for this great work!

I installed crDroid 7.13 and try now to install GApps.
CrDroid is working properly, MTG from link of the first post also runs properly, but GApps are not installed.
If I reboot to recovery and try to install them again, I get the message that not enough space is available.

I tried it then with TWRP-3.4.2 but I am getting the same message.
Even with OpenGapps (down to pico) I am getting the message about "insufficent storage space available".
Logfile is attached if this helps.

I tried no to install first CrDroid first, then reboot to system, reboot to recovery, then install GApps.
Also tried to install Cr an GApps in a zip queue.
Also tried it with SHRP and TWRP.

I want to increase the system partition size, but under advanced wipe there is no system partition to select.

Does anybody have a hint for me?

Thanks and regards,
huntworker

Redmi Note 9
Hi all,

I was running PPUI 3.10 on my Redmi Note 9 3GB / 64GB until it entered a bootloop. I managed to access EDL mode by using the bypass scripts from step 12 of this guide by @vagelis199. Next, using SPFtool, I flashed MMUI, seccfg (to restore bootloader unlock) then I flashed recovery, vbmeta, PPUI ROM, and userdata partition which allowed me to decrypt and backup my data.

I again flashed MMUI (merlin_global_images_V12.0.3.0.QJOMIXM_20200804.0000.00_10.0_global) and then followed the steps to install crdroid, however then the phone started freezing on deep sleep (i.e. when you turn off the screen). This I managed to solve by flashing MIUI firmware upgrade (fw_merlin_miui_MERLINGlobal_V12.5.1.0.RJOMIXM_84b071b256_11.0.zip from here https://forum.xda-developers.com/t/...-0-rjomixm-redmi-note-9-redmi-10x-4g.4321093/)

So far I've found this ROM much more performant than PPUI which I'm very happy about. Let's see how it holds up!

Thanks a mil @Evan_Ferrao and crdroid team!

There's somehing weird with the ImeiBackup file, I downloaded it and my antivirus detected a setup.exe as some kind of trojan: Trojan:Win32/Wacatac.B!ml. Anybody faced the same issue?

Also I installed the rom and now I'm stuck in a boot loop. Needless to say I followed all the steps from the instructions.

I've installed crdroid latest version on top of miui latest version.
Everything works well except for the fact that volte and vowifi don't work.
I've turned them on and my carrier does support both however when I call with mobile data on,
it turns off meaning volte doesn't work.
I tried *#*#4636#*#* and went into ims and it said that IMS is not registered.

Help

I've tried restarting, reinserting the sim, I flashed latest firmware but still volte and vowifi are not working.

To get VoLTE working, I downgraded to MIUI 12.5.2 using Mi Flash Tool (the firmware upgrade/downgrade didn't work for me). I clean flashed crDroid again and voila! (Note that VoWi-fi isn't available for me because I am not connected to a Wi-Fi network.)

I got VoLTE working by downgrading to MIUI12.5.2 taking hints from other posts in this thread. The firmware upgrade/downgrade doesn't seem to work with me. Also, a major downside now is the issue with the disappearing call screen (the phone only rings and doesn't show the answer/reject popup/screen). I flashed the latest Gapps for Android 12 but that doesn't seem to solve it at all.
