Yes, both. And i made sure it was the canary build
Hmmmm that's very strange. It seems you've completed most if not all the instructions on point and still aren't booting the ROM. I wish I could be of more help, I guess my best advice would be to re-do the instructions 1 by 1, maybe you'll see something different you didn't see before. You could also join our Telegram group, maybe someone there knows something I could have missed or went through something similar.
 
just installed this rom this morning, so far performing well. just need a kernel and we're golden. also, how do I remove the power button from the notification panel? is it in floating_features? Also how do I remove the wide selfie from /system/cameradata? My phone gets stuck in a boot loop

I managed to flash the NcX v2.5.2, disable encryption and magisk without a problem. My only problem is that I notice after rebooting and running magisk manager, I keep failing the safetynet test. I passed the basicintegrity but failed the ctsProfile test. It also keep showing error message of "evalType Hardware". I did have Magisk Hide enabled but still gets the error.

Is this a known problem with this Rom? I am currently using Magisk 21.1zip flash supposedly the latest Manager v8.0.3 from https://magisk.me/. But I noticed from reading the latest posts above, the recommended Magisk for root is the canary build. Can someone provide me the flash zip link for canary build? I cannot find it on magisk.me website. Also, has anyone notice Safetynet working once using Magisk canary build? Thanks for the awesome custom rom.

No rubbish samsung bloatware in this, is there.
I have stock rooted and not done a rom install on my A71 as yet, but this is tempting.
Thank you

With my old andriod device, whenever i did a trwp backup, the partitions involved were just simply system, boot, modem and data. now with andriod 10, I see so many extra partitions. I am confused. Which are the essential partitions to backup for this rom? Do I backup boot, modem, data, efs, optics, prism and super? If all the partitions need to be backup, then the final file size will be too big for my sd card. Could someone give me some pointer on this matter.

I try to search for answers online but most info are outdated and applicable for older devices. Besides, when I go on Twrp backup, I don't even see "system" as an option for backup. I guess it is because this rom is flashed using "super" img file over the system partition. So technically just backing up super, boot, and data partitions should suffice, correct?

Thanks in advance for any tip.

Okay so I got it running after updating to a U3 bootloader. It now runs normal.

I'm using much less bluetooth now, but since I've installed NcX 2.5.2 my phone doesn't remember the paired devices, I should pair them every time I use it, somebody had or has the same problem?

There's a Magisk module called "Bluetooth library patcher" which fixes this issue. Apparently, its a common problem with rooted Samsung devices.

Would love to have this, I will wait for camera issue to be resolved.
Unless it has already been corrected.
Best wishes

Anybody know why, when I flash my phone, I still get my old OS??
I did as the instructions said, but both time I go back to my old OS.

Thanks

Oh, yeah, how come I don't see TWRP in the package? Am I doing something wrong?
Ok, everything worked out. Got it installed. I didn't install 2.5 first.

I haven't found any problems so far on the ROM. I will test more tomorrow. However, if you were to update in the future, is it possible to shut off "Emergency Alerts?" These are the annoying alerts we get about missing people in the middle of the night.

Thanks.

    NcX 2.5 A71 ROM
    Pretty straight forward, I took OneUI 2.5 firmware, debloated it and added a few features which can be found here: Link to MODs
    My plan is to make this the best version of OneUI 2.5 with more features and fixed things (my mission is to fix Secure Folder in the near future) Fixed :)
    Anyway, let's get started.

    Code:
    Your warranty is now void. 
    * We are not responsible for bricked devices, dead SD cards, 
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about flashing this ROM
    * before flashing it! YOU are choosing to make these modifications, and if 
    * you point the finger at us for messing up your device, we will laugh at you. HARD!

    Features!
    • TWRP Included
    • Full OneUI 2.5 features
    • Debloated
    • Added camera features
    • Dolby Atmos without earphones
    • Optimized
    • Edge Lighting fully enabled
    • Secure Folder fixed
    • Smart View fixed
    • Samsung Health fixed
    • Samsung OCR service

    Bugs!
    • Secure Folder broken (will try to fix later) Fixed on 2.5.1
    • Samsung Pass broken (because of knox 0x1, duh) Removed from ROM, it will never work.
    • Bug with AOD brightness when you use fingerprint unlock method. This bug happens when you have AOD to always show. If AOD is showing, then you turn the screen on to only show lockscreen clock and then turn the screen off for AOD to show, the brightness of AOD will reduce to the most minimal and it will be hard to see, regardless of what brightness you set up. There are 2 ways to getting rid of this bug:
      • Disable unlocking phone with fingerprint
      • Unlocking your phone and then locking it again. This will only fix it until you trigger the bug again
      Fixed, clock animation removed.
    • You tell me

    Changelog!
    • 25/Oct/2020 (NcX 2.5.2):
      • Added 60 fps recording on selfie cam
      • Added wide selfies. (a biiiiit buggy, but serviceable)
      • Added 24 fps recording modes on pro video mode
      • Fixed Samsung Health
      • Added Samsung OCR Service for better text extraction
    • 12/Oct/2020 (NcX 2.5.1):
      • Secure Folder fixed
      • Smart View fixed
      • AOD bug fixed
      • Removed Samsung Pass
      • Removed Samsung Daily
      • Removed "Tips" app
      • Removed Bixby
      • Added camera features
    • 08/Oct/2020: Release

    Links!
    Prequisites
    MANDATORY ALWAYS: SD Card. It IS possible to have it on internal storage but ONLY if you are not encrypted. If you are encrypted, then you will need to FORMAT DATA and that will delete everything in your internal storage and you won't be able to add it back to internal storage with TWRP because MTP is broken.​
    For installing 2.5.1/2.5.2:
    • Installing and following NcX 2.5 installation steps, as well as its prequesites
    • TWRP Installed (included in NcX 2.5)
    • Download multidisabler.zip (link: From Telegram Group (also attached on this thread) and add to SD Card or internal storage
    • Download Magisk zip installer to your SD Card or internal storage

    For installing 2.5:

    • Update to bootloader U3 (either install OneUI 2.1 or OneUI 2.5 fully with Odin), otherwise you will have problems with camera
    • Fully unlock bootloader. I don't mean just turning OEM unlock on in developer settings , I mean FULLY unlock. If you didn't know, Samsung changed up how you unlock the bootloader on newer devices like this one. @topjohnwu gets a little more specific here: Explanation but I'm going to quote the important stuff to FULLY unlock bootloader:
      Unlocking BL on modern Samsung devices have some caveats, so I figure this would be helpful.

      Allow bootloader unlocking in Developer options → OEM unlocking
      Reboot to download mode: reboot and press the download mode key combo for your device.
      Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
      If you think the bootloader is fully unlocked, it is actually not! Samsung introduced VaultKeeper, meaning the bootloader will still reject any unofficial partitions before VaultKeeper explicitly allows it.

      Go through the initial setup. Skip through all the steps since data will be wiped again later.
      Connect the device to Internet during the setup.
      Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
      Your bootloader now accepts unofficial images in download mode.
    • Download Magisk zip installer to your SD Card or internal storage
    • Download multidisabler.zip (link: From Telegram Group and also attached in this thread) and add to SD Card or internal storage
    Instructions!
    For installing 2.5.1/2.5.2:
    • Reboot to TWRP
    • Flash NcX 2.5.1.img or NcX 2.5.2 as "super" image in TWRP
    • Reboot to Recovery
    • Format data if you are coming from Stock ROM. If you are coming from NcX 2.5 then you don't need to wipe or format, you can just skip this step.
    • Flash multidisabler (this is required always)
    • Flash Magisk zip (optional)
    • Reboot and wait patiently
    For installing 2.5:

    • Reboot to download mode and add AP_NcX 2.5 A71 in AP on Odin
    • Uncheck the Auto reboot option in Odin
    • Flash
    • When it is finished, force a manual reboot (keep pressing VOL - and Power buttons together)
    • Immediately when phone reboots, boot to recovery mode (VOL + and Power button)
    • If your phone was unencrypted before, just do a normal wipe. If your phone was not unencrypted before, do a full data format (Go to WIPE option in TWRP, select FORMAT DATA button at the bottom and they type yes on the keyboard. This will completely wipe your internal storage so be sure to backup and photos, music, etc... you have in internal media.)
    • Flash multidisabler to ensure you do not get encrypted
    • Flash magisk (I don't know if this is mandatory, I would fully recommend it though)
    • Reboot and wait patiently

    How to report a bug/Ask for a change

    Over the small amount of time I've been doing my edits and shared them with the community, I've noticed something that seems to irritate me. I can't speak for all the developers on this forum, but I do edits/ROMs/PORTs/etc... to what I like. I don't work for anybody else but me. I share my work because it may have something of value to other people and/or some people may share the same taste as me on regards to what they want on a ROM.

    That being said, that doesn't mean I will completely ignore what the community has to say.

    First and foremost, it must be said, I am merely a beginner. I do not claim to be a professional developer that knows how to add everything, I am nowhere close and I learn as I go.

    There are ways to ask for something and/or report a bug when it comes to ROMs, and this post is my attempt to try to explain how to (and how not to) report a bug in order to help me out as much as possible to try to fix something

    You can also ask for something to be added, but there are also ways to ask for something


    So, here we go

    Keep in mind:
    • I do not add stuff that can easily be downloaded from the Playstore
    • I, myself, don't do kernel edits
    • I COULD remove stuff if NOBODY uses it



    ---REPORTING BUGS---​


    How NOT to report a bug:
    • "SystemUI (or any app)is crashing, please help!"
    • "Instagram doesn't allow me to edit my post, what could be wrong?"
    • "My bank account app is not letting me do such thing"
    These posts are sort of pointless as they only state something but I have no context on what could be causing it. Also, I can't really control (for the most part) third-party apps, so if you're going to ask about them this way, don't even bother

    A slightly better way to report a bug:
    • "I clean installed the ROM and was working fine, after I installed Facebook and logged in, I immediately uploaded a photo and SystemUI started to crash. Can you look in to it?"
    • "I tried to install Black Neon theme (a link to it would work as well) and it was working fine until I tried to activate AOD (or anything else for some reason) and SystemUI (or any other app) is crashing, could you look in to it?"
    • "My bank account app doesn't let me take a screenshot of my accounts. I get a toast notification saying "Can't take screenshot due to security policy"
    As you can see, this provides a bit more context and explanation on your current situation. This gives me a little more detail on trying to replicate the problem and hopefully could fix it by replicating it. Well, except for point #3 which is out of my hands for the most part (I think). If you include what kernel you're using would make everything better! Also any significant change that would require root (like xposed and or anything that modifies /system also needs to be informed for better results)

    The BEST way to report a bug:
    • LOGCAT!!!!!!!!!!!!!!!!!!
    Please learn the ins and outs of a logcat, this really helps a lot on finding what the problem is. Also, please give a brief explanation as the above examples when providing a log cat :)








    ---ASKING FOR STUFF TO BE ADDED---​


    How NOT to ask for stuff:
    • On your next update, add iris scanner
    • You should add (app) on your next update
    • Hey, please add (app or feature) on your next update
    No, I do not work for you. Even if you say please like the third example, that doesn't mean you're being polite. It still sounds like an order lol so you should probably rephrase your request.

    How to ask for stuff to be added to my work:
    • Would you be so kind to add (feature) to your ROM, if possible?
    • Would it be possible to add this app to your ROM?
    • Please, can you add (feature) to your ROM, if it isn't much to ask?
    See how politeness makes everything better? You're not demanding it, you're just politely asking to see if maybe it is within my grasp to add something. And if all request would be like this, I can assure you I'd try my best to add said feature






    I hope this is useful to you or I at least hope that some people read it.
    If not, I can just tell you to return to stock ROM, probably better than any ROM I put out anyway :p
