    Download in incognito mode.
    If that's the case, it's not full proof. But thank you, it's functional now.

    To bypass it, you can simply take a screenshot then click share in some editor (I used simple gallery) and that works. But the actual screenshot isn't available after that
    This toggle is useful when you hand your phone to someone else. Clearly, they are not going to do a research on how to go around this... .
    The first boot after update could take 5-7 minutes. If you still can't boot, then your second slot doesn't have OOS-11. There is no other reason.
    I did it! It took me like forever but I was able to update to the newest version. I sent you something on paypal as appreciation for your great work!

    What I did to get it work:
    - TWRP Backup (only Data Partition) of my current system
    - Wiping everything
    - Installing OOS 11 via fastboot on both slots
    - Installing JaguarOS V26 via ADB on both sloths.
    - Wipe / Factory Reset (in TWRP)
    - reboot into System (needed to rebuild data partiton)
    - Back in TWRP: restore data partition
    - reboot (will take 5-10 mins)

    I had to do it this way maybe because I didn´t follow the step by step procedure from optimumpro in the beginning properly. :)

    See important discussion about Kernel Updates and Security: here

    Jaguar is available on locked bootloader with working root (Magisk)

    SAFETY NET IS SUCCESSFULLY PASSED WITH MAGISK 24.3 and up. See instructions here

    You can actually use alarm when the phone is shut down. It would boot 2 minutes prior to scheduled time and trigger the alarm on time

    This is official Jaguar Rom.

    I have been building Android roms since 2012 for various devices including multiple Sonys, Lenovo Zuk, Oneplus 3, Oneplus 5 and Oneplus 6. You can check my Oneplus 6 or
    Oneplus 6T threads and browse my profile.

    Jaguar rom is focused on hardening of AndroidOS and kernel. As such, the rom has hardened bionic, art, framework and tightened security.

    1 Rom control with custom Power options, Statusbar, Buttons, Navbar, Quicksettings, Lockscreen, Notifications, Gestures, Themes etc...

    2. Heavily modified Art, Bionic System/Vold and System/Security

    3. Telephony response to Type Zero sms ('silently acknowledged') disabled

    4. Toggle to disable Captive Portal logging.

    5. Speakerphone proximity sensor toggle - could be set to automatically switch to speaker when not at the ear

    6. IMEI and phone numbers hidden in About menu

    7. Built-in encrypted DNS providers, such as: Cloudflare (US); LibreDns (Germany); AdguardDns (Cyprus); and PowerDns (Netherlands)

    8. Wakelock and Alarmblocker

    9. Fully working Call recording with the button visible in Dialer

    10. A choice between the latest Bromite and Vanadium webview

    11. Deskclock app modified to work with PowerOn alarm. The app will boot the phone 2 minutes before scheduled time to trigger the alarm on time

    12. Default Dark mode

    13. All regular customizations plus. You tell me which feature is missing.

    Install instructions

    If this is your first time coming from stock, you need to have stock Android 11 in both slots. So, either update stock OTA to populate the second slot or flash stock rom with TWRP. Do not use Lineage's 'transfer' script, as this might corrupt your persist partition. In addition, that script transfers outdated files.

    1. Install Jaguar recovery from (from post #3) via fastboot: reboot in fastboot and execute the following commands on your connected PC terminal:

    fastboot flash recovery_a recovery.img
    fastboot flash recovery_b recovery.img

    Or use TWRP

    2. Download the rom to your PC. Boot the phone into recovery, set recovery for sideloading, then type on your PC terminal (which should be opened in the same directory where you had downloaded the rom):

    adb sideload 'name of the rom'

    3. Factory reset and reboot. You are done. If you want root, just install Magisk manager (apk) from here as a normal app. Don't flash it.

    PICO Gapps has been tested successfully with this rom

    The rom could be used on locked bootloader with ROOT (donate feature) with or without Gapps.

    The benefits of LOCKED BOOTLOADER combined with WORKING AVB-2 protection are:

    You get your DRM L1 back (one full stock update required). Many banking applications (tested several) will work even if Magisk is not hidden: you simply get a warning, your device is rooted, but can click 'don't show again' and proceed to login.

    Nobody and nothing can modify Kernel, Recovery and Virtual Partitions without triggering a red screen of death with the message 'your device is corrupted and cannot boot'.

    At that point, the only option is to unlock bootloader. But, if a user had previously disabled OEM unlock in Developer settings, then unlocking becomes unavailable, and so does flashing via fastboot. In other words, if your phone gets into the hands of an adversary, their only option is to use MSM tool to make the phone work again, but no access to your data or any other partition.

    Recovery: Here

    April 11 New release V-19, previous one removed. Should fix graphic glitch related to recovery.

    Actually, you can use any recovery you want: TWRP/Lineage or whatever. Just keep in mind that if you don't have OOS-11 firmware in both slots, you will always get problems. MSM flash takes care of one slot only. So, you need OOS-11 in the other slot either by flashing via recovery (after initial reboot) or updating OTA.

    Also, you don't need MSM, if you can't boot into recovery. You simply boot in fastboot and flash whatever recovery you want.

    This release fixes Safetynet issues. Confirmed by a Oneplus 8 user: here

    1. April security patches
    2. Google r54
    3. Switched to AOSP webview 100.x
    4. Should work with Zgisk

    Dev should really consider dropping support for 8 pro. Clearly just because his device doesn't have the issue he thinks everyone's device should be the same 😂.
    Two people have mentioned the same issues and instead of fixing it he's showing screenshots. DFKM.
    I'M DONE
    Lol take it easy man, he's just sharing a ROM, theres no obligation here.

    As frustrating as it can be to not have working features it's still an "as is" ROM, no need for hostilities.

    I haven't personally installed this ROM so no i can't comment on features missing or not but i can on how to address them, there are ways and means to get a point across without sounding deserving of something you aren't.

    If you've clean installed and there are missing features then just mention that, if it gets fixed then great if not then that's just the way it is, no ones under any obligation here, speaking down to dev's who've put the hours / days / weeks in to share something for FREE is what makes people leave and not share their work, XDA wouldn't be a very good place to be if dev's didn't do what they do and even worse if they didn't have the support of people who flash their work, please bare that in mind.

    [Thread Cleaned]

    A very good morning to you all! Some posts have dissipated left and right but I hope we didn't cause too much (collateral) damage. I hope y'all got it out of your system and feel better. Now, let's move on and stick to a more civil way of communicating. With mutual respect and all that.

    About donation features: YES, IT'S ALLOWED! Sometimes. Shocker, I know. The moderation team may be tasked with – among many many many other things 😬 – shutting down projects that have only the goal of making money but this does not mean that donation features are forbidden. We expect that core features and most important functionality of any release remains free. We also understand that developing software is hard work which should be rewarded. Our goal is to find a balance and we do this together, as a community. To achieve this we often work with developers to find the best outcome for everyone.
    Please do not throw around accusations in someone's thread and never threaten another member with sanctions. That's just not okay. Even mods will avoid this. It may come as a surprise to you but we're not the Cyberdyne Systems Model 101 designed to terminate your threads, posts and accounts followed by a taunting “Hasta la vista, baby”. We're human beings with elevated forum rights and a lot of XDA experience that interact with all its members with the goal of keeping this kickass community a pleasant experience for all.

    Thank you for your time and I sincerely hope we can show more kindness to one another. [cheesy]“Sometimes it takes only one act of kindness and caring to change a person’s life.” – Jackie Chan[/cheesy] If you still feel the need to discuss further, please feel free to drop me a PM. And if really needed, "I'll be back" ;)

    Kind regards and stay safe!
