It's a very good news for the CR7 user ! You should know to the 7.16 version has issue to pass safetynet (cts profile mismatch) while the 7.15 pass it without issue.

I can't help for the kernel, I was't a dev, maybe custom kernel maintainer can help you.
Better to upgrade to newer CrDroid 8.7 based on Android 12.1, I don't see any change to the repo, so it will be a waste of time downloading so much stuff, I have seen videos on newer CrDroid and it seems they fixed the rom and is very stable now.

I already tried CR8 few months and was very disappointed (NFC not working + the UI was extremely ugly). Only 1 custom A12 rom is very stable with just a ok UI but the real problem will stay the trash base provided by the google UX designer.

In my case, I will test another A11 rom for see if it got the same scoped storage issue than CR7. My final setup will be a A11 roms, we are lucky to still got the choice to use A11 unlike the 2O22 phone user.

We had Lineage 18.1 available but they deleted all roms from A11

You can't do a dirty flash from Cr8 => 7, a clean flash of the rom will be required in that case.

You need to backup your user app with swift back up, your contact on a vcf file and the photo or any important data manualy into a safe place (on the cloud or another device).

Then remove your lock pattern (for remove encryption), and place a SDcard with CR11 .zip, gapps, magisk. Reboot on recovery, check if your SDcard is recognized then wipe system, data partition and flash Cr7.

If Cr7 was stuck at the boot logo or if your recovery can't decript the files after set a lock pattern, you will need to format data.

I use microG so I don't know which is the best gapps version (Nikgapps should work).
While cr 7 booted successfully, you can import all your data.

actually they were two different questions, but thanks for the answer!
question a. going to cr7 from cr8. from your answer i deduct that you just have to do a clean install of the rom with format data, no miflash tool required.
question b (still unanswered). can you dirty flash cr 7.21 on top of cr7.18?

I did a OTA update from Cr 7.15 => 7.21 on Orangefox 11.1_2 without any issue so dirty flash should work to.

I too would like to confirm
1. cr7.21 16 Aug update works better, both battery and performance wise and with less warning errors than the earlier buggy cr7.16 March cake, specifically due to continuous update requests. A much sought after update. Appreciate dev works @neobuddy89. Would request that even a half yearly updates to such a stable branch is good for us all, do give it a thought.
2. Yes like all other roms the dirty flash mostly works within same version series.

thx for your helpful reports. Since 7.21 is in use without GApps here I wonder if not only for c. those are necessary (without extensive magisk messing)? Can you explain which type of screen casting you have tested?

the previous version was unable to detect my hyundai tv when i had its input ro "wifi".(on the device: settings -> connection prefferences -> cast). i was able to overcome this with a simple modification of build.props. however, this version has updated security patches and since the update is hustle free, i see no reason in not applying it.

    Thx, I would like to check screen casting from 7.21 (or Stock for comparison) to a Android TV
    LineageOS 18.1 system. You comment has encouraged me to try it. I may also try some tweaking regarding Banking Apps, even if I try to avoid making the Smartphone the device for everything (I prefer Desktop-Banking also regarding GUI+keyboard/mouse usage).
    screen casting is ideal for family games like wheel of fortune or picture showing. as for banking i find nfc payments quite useful. :)

    Thanks for the person ever build this new rom from CrDroid, I have downloaded all repo but it always gave me error when building the kernel, I guess it must be done with someone who has lots of knowledge, also when compiling, normally won't came with MIUI camera, this rom is superb and X3 Pro is working flawlessly.

    Features:
    https://github.com/crdroidandroid/crdroid_features/blob/11.0/README.mkdn


    Install instructions:

    Pre-installation:


    Flashing Instructions from any custom ROM (Thanks to Raf & @kamild_)
    • Backup all your data.
    • Transfer ROM and other zips (such as Gapps or Magisk) to internal storage, SD card or USB drive.
    • Boot/reboot to recovery.
    • Flash recommended MIUI firmware 12.5.5.0.
    You can find them here. If you're already on it, you can skip this step. You can flash the fastboot version of the MIUI stock ROM through Mi Flash tool / Fastboot too but the procedure is slower.
    • Flash CrDroid ROM.
    • Flash GApps (Optional step) FlameGapps
    • Flash Magisk (Optional step, only if you want root)
    • Format Data > type "yes" and press enter (different from the "wipe data" option)
    • Reboot to system



    First time installation from MIUI 12.5.2.0 or above:

    1. Remove any fingerprint, PIN, or password in MIUI. Backup all your data, next step will factory reset the device.
    2. Unlock the bootloader.
    3. Flash recommended custom recovery from the "Prerequisites" section with fastboot.
    4. Continue from step 2 of the "custom ROM instructions" below.


    UPDATE INSTRUCTIONS:​

    OTA Working: Just update from OTA screen

    Manual Update installation:

    • Reboot to recovery
    • Flash Rom (default path: root/data/crdroid_updates)
    • Wipe Cache/Dalvik
    • Reboot

    this is a missing feature, unlocking works, but lacks a choice of fingerprint scanner behavior
    Yes, I need to check how to implement in vayu.

    I'm happy to say we have Official Support!

    Thanks to all for your comments.

    New update avaiable ;-)

    ViPER4Android FX and James DSP Manager - Break Wi-Fi, simply won't turn on

    After installing NLSound 2.3, the sound starts to wheeze (upon notification), this is when properly configured, as it was done on other roms.

    These modifications can be installed in magisk and working properly on other roms

    However, nice rom!
    Thanks,
    Sorry, some magisk modules are breaking device overlays so I don't support modules for now.

    and fingerprint press and touch toggle
    is dynamic refresh rate possible to add like on arrowos
    Dynamic refresh added in next version.

    fps info fixed

    CrDroid was always one of my favorite roms, the only things that are a bit annoying are:
    - press fp to unlock button that one of poco x3 nfc devs made it possible.
    - haptic feedback when you pull down status bar...
    thanks
    (press fp to unlock button) I have tried it but commenting on it with more people I do not know if it is the best option.
    There is no option to select the button behavior.
    There are reboots when using trcamera and Google meet the log also has camX errors spammed
    View attachment 5328217
    Will be fixed in next versions
