I tried to reflash therom again and now I'm stuck at bootloading. It doesn't loop, it's just stuck. Also whenI'm flashing, it says Failed to Decrypt Data. What can I do to fix this?

Hi all,
maybe it is a stupid question but let's try....

If this rom is based on S21FE stock firmware, may we use the custom rom released for S21FE phone on our A52S 5G ?


Thanks


NOTE
I take the occasion for express my gratitude for this fantastic rom to ShaDisNX255

After a couple of week of using, I have had all run smoothly and no matters happens so thank you again,

    Development Update!
    Those of you who follow me on Telegram already know this, but I've began work on NcX in OneUI 6
    It's pretty much complete and ready for release, but I thought I would make a few statements before making the official release

    NcX is undergoing big changes for the sake of ease of development and stability.

    The first big change is that I will no longer be basing NcX off S21FE firmware.
    What does this mean? Well NcX will now be based on stock firmware. So stuff like DeX will be permanently removed.
    Why go this route? Simple, this will reduce the amount of work I have to put on each release and therefore make updates faster to roll out. It also means that NcX will no longer be bloated with stuff that the hardware may not support.

    Does this mean NcX will lose most of its features that separate it from stock? NO
    Working with S21FE firmware has taught me a lot on how these features work and I'm pretty confident I can bring back most of the flagship features to this new version of NcX

    Unfortunately, the only feature I won't be able to bring back is DeX. However, there is a silver lining to this. BlackMesa is currently working on a project called UN1CA which will be a full S23 port with DeX included
    I'm more confident his ROM will be much more stable than what I would be able to provide. So people who enjoyed using DeX will feel right at home with this new upcoming ROM


    And now for the other bad news, I'm stepping away from the advanced installation that used to come with the ROM. That means the ROM will be a single image, no more 2-step ROM installation. It will be a single flash and the ROM will ship with with pre-determined apps.
    I will provide a separate zip to do what the advanced installation did, but it will no longer come shipped with these options. The main reason for this: OTA updates.
    OTA updates are now more stable with this single image approach and without the 2-step installation method.


    And that's pretty much it. Been testing OneUI 6 for a bit and I'm really liking how smooth it feels. With the new TWRP, NcX is now encrypted and can be decrypted in recovery, so that's an extra benefit for privacy of users. I'm working on the new NcX all this week and will probably make the official XDA release during the weekend. Stay tuned.

    FAQ
    Q: Will this work on A52 4G or A52 5G?
    A: No, I included A52s 5G specific vendor with hw libs. This will only work on A52s 5G

    Q: Will this work on A73 5G?
    A: I have no clue. I've been told HW is very similar with a few lib exceptions but I honestly have no interest on supporting this device. Anyone else is free to try and flash and fix it for A73, you've got my support.

    Q: How can I report a bug?
    A: Try and be as detailed as possible on how you encountered the bug. If you can include a logcat then even better. The more information provided the more likely it is to get the bug fixed.

    Q: I'm getting a bootloop, what can I do?
    A: There are 2 common fixes for this. If you were on stock ROM, then it's most likely you didn't do a format data. Please note that doing a full format of data and doing a simple data wipe are 2 completely different things. Make sure you're formatting. The other common fix for this is flashing either a custom or stock kernel. This usually happens when you were previously using an AOSP ROM like Lineage, PE or crDroid and you installed NcX without going to stock ROM first.

    Q: Can I flash this ROM without wiping my phone (dirty flash)?
    A: There have been reports of this being successful, but I never do it myself. I always try to use the same bases to make the ROMs so in theory it can be done similar to an OTA update. All up to you, a clean wipe is always recommended for the best performance.

    Q: Help, I'm getting "secure check fail :" what should I do?
    A: This is usually an error produced by mismatch in bootloader and the ROM images. To fix this, the easiest way is to install the latest stock firmware or the firmware best close to the version of the ROM you want to install (install February 2023 firmware if you want to install NcX February 2023 or install stock March 2023 firmware if you want to install NcX March 2023...etc...)

    Q: Why aren't OTA updates installed automatically?
    A: There's a bit of unfortunate news regarding this. Current OTA updates depend on TWRP's openrecoveryscript which seem to be broken on the latest TWRP official releases on both my A52s and A52. I don't like bothering TWRP devs or maintainers so I've passed on reporting it because it's really not widely used and for some reason stuff like crDroid OTA works fine on it. It could be that I'm working with outdated code but I'm not skilled enough to fix it.
    If you want to keep using the latest TWRP, the way you install OTA's is following:
    • Download the update when available
    • When pressing Install, it should reboot to recovery. If it doesn't because you don't have Magisk installed, reboot to recovery manually
    • Once in recovery, select Flash on TWRP or directly navigate to the following directory with OrangeFox
    • sdcard/Android/data/com.mesalabs.ten.update/files
    • Flash the zip in the directory and wait for update to finish
    • [Optional] Wipe cache and dalvik cache
    • Reboot to system
    If you want to use an outdated TWRP with openrecoveryscript working fine (which I really don't recommend unless you only want to use NcX and not any other ROMs), you can install the attached TWRP build which is unofficial and should not be used for any AOSP ROMs. The only benefit you'll get is that OTAs will get installed automatically.
    This may be fixed in the future but for now, this is the current state of OTA updates

    Announcement:
    Do not update to the official February security patch if you want to continue using this ROM.
    Samsung bumped the bootloader version and NcX will not work due to BL version missmatch and you will not be able to downgrade to January security patch as well!

    NcX will not update to February security patch. S21FE firmware is already in OneUI 5.1 so NcX will only update after this device gets OneUI 5.1 officially.

    You have been warned.
