Roms for Excalibur

[Amnesia_A9]

Since an unofficial twrp is available now and I've found some new roms, this post is an update
There are plenty of roms if you know what to look for, you just need to look for custom roms for "miatoll" and you'll find a couple of roms.
I will still add the links over here.

The roms I found earlier
Pixel Experience

Msm extended

The new ones that I have tried in the last 7 days:
Arrow os
Evolution X
Freaky Os
Pixie Os
Pixel Extended
Stag os
Statix Os

Telegram Channel
MOD EDIT: Link Removed

Join that telegram channel and you'll find all the download links.
Except the freaky os, rest of the rom had pretty smooth ui
While flashing any rom if you get the error: couldn't find or mount "/system_root" or "product"
Ignore it and reboot the system normally, you will get that while flashing pixis os
Statix os is based on android 11 but after flashing it, I wasn't getting any network signal.

Thank you so much for this thread, you won't believe me, but I did the exact same thing, I flashed the stock rom and locked my bootloader by accident, now I have a 20 day wait period. I'll try these and report for bugs, sot, charge speeds, etc. Hope development picks up pace. Really love the phone.

I am also getting error 7 for flashing any rom.

 

[Vijo123]

U can "reboot to recovery" again.
Then flash the ROM.
U won't get Error 7.

we could really use an unified thread like we have one for the t and non t series oneplus devices that is cross device development link.
Reasons? copypasta from the one of the roms link from the op's post.
Q: What do you mean by "Unified" in the thread title?
A:*Redmi Note 9S or Indian Redmi Note 9 Pro (curtana), Redmi Note 9 Pro Global Global (joyuese), Redmi Note 9 Pro Max (excalibur), POCO M2 Pro (gram) are basically the same devices, the only significant difference is the 33W charging support on the gram, joyuese & excalibur with joyuese having NFC as well. So I have decided to do a single, unified build for supporting curtain, Excalibur, gram & joyuese.

Hi! Unfortunately that's something I don't have control over. You can try requesting this in the New Device Forum Requests thread.

Hey yo, thanks for the reply, but don't I have to wait for my mi account to her developer permissions? That'll take longer than the wait period I think

I got a waiting period of 168 hours .Simple procedure. Unlocked already.

 

[iamparven]

Reporting back after testing following roms.
Arrow OS - Launcher 3 looks weird it never showed the date and weather widget, search widget looks weird, fast charging not working tried with 33w and 18w, Amazing thing is ANXcam is included in this rom.
Pixel Experience UNOFFICIAL - Never passed the setup screen it always crashes after clicking next on the very first setup step
Pixel Experience OFFICIAL[MIATOLL] - Fast charging does work.
Evolution-X - Works good. fast/turbocharging information showed are wrong. useful customization options. and to be honest a good support community
Device - Note 9 Pro Max [Excalibur]

I got a waiting period of 168 hours its is general process , tomorrow i will unlock bootloader my waiting time will be over today. Such a ****ty process to unlock bootloader its just take couple of minutes in other phones why i can't understand the chinks want to delay unlocking phones. BTW i want to unlock bootloader to install VIPER4ANDROID i just love it using this app since my last three phones not for custom rom....

Why no official ROMs for this device?
I was planning to buy, but with no Custom ROMs around, I am rethinking.

Official roms are there. Just the thing is that the custom roms for Xiaomi phone having 720g processor are being developed under "miatoll" codename
Its like Mi= Xiaomi
Atoll= 720g processor
PixisOs, pixel extended, Msm extended, Crdroid all are official roms

Try pixel extended , it does support fast charging , good battery life and its smooth just less customizations and you will have to flash anx camera manually.
