A few months ago I flashed your V13 and since then my USB socket hasn't worked. Until today I was looking for a desperate way to get an update and then I came up with the idea to update my Rom to 21 via TWRP that I flashed via Magisk. Said and done. Since the new reboot, my root is gone and the boot screen, i.e. the animation of your ROM, is colorful and pixelated.

Magisk is no longer prebuilt. How did you flash 'via Magisk'? If you are using TWRP, just flash V21 dirty (without wiping data) again.

I use the official TWRP build for the 8 Pro and Flash it over the Magisk Version from V13. Problem now is, i dont have the Option to use my USB Port..... And root is gone, so I cant Flash anything without magisk. :-(

I have no idea what you are talking about. What does Magisk have to do with flashing rom via TWRP or for that matter any recovery?

Also, in TWRP, you must enable MTP and that will give you access to USB. If you have no USB generally, this means your Windows drivers are not good or not updated. Access to usb in recovery is not dependent on the rom. Official TWRP has its own kernel which boots separately from the rom, and if you have no access to usb in TWRP, that's either your PC problem or phone's hardware (unlikely) or usb cable.

Yesterday. It happened the same with me. Push the vol up and down and power button and hold till it boot into bootloader. After that I couldn't boot into jaguar rom so I went back to oos with mms tool.
I thought it was somehow my fault but it seems to something wrong in the rom or the install guide. I follow the guide step by step. I hope optimumpro will have a solution because I want to use this rom.

Thanks for the reply man. Didn't bother updating either OOS or lineage, i just sticked with your ROM. Thing is i cant even boot into any mode, it just hangs at the boot screen with colourful pixelated screen.
The issue you are having has to do with the second slot on your phone not working, i.e., no OOS-11 in second slot. Check the telegram group: just today there was a report of a successful installation of V21 on Oneplus 8 Pro.

I'm seeing the same thing.
Installed the ROM some time ago, and have successfully dirty flashed the last two releases. The phone has been working fine since then.

Today I did a "adb reboot recovery" and got into the same problem. After trying a few times I managed to boot sucessfully once. Stupid as I am I did a new reboot and now I'm completely stuck. It just hangs with a mosaic bar on the top.

I can power off using both volume keys and power, and I can get to bootloader using the same keys.

But booting from bootloader fails every time, even booting to recovery.
I've also tried flashing recovery.img again to both slots, no go.
"fastboot boot recovery.img" also fails in the same way.

Okay. This seems to be a problem with the recovery.img for the latest release.

I tried to boot twrp from bootloader and that worked fine.

Then I flashed twrp to both recovery slots and now I'm back up and running again.

hey man, how did you manage to boot into twrp from the bootloader? have been stuck for a week now, really contemplating a full reset if i still can't get it working. Thank you
Download latest twrp, there is a thread in this forum I believe.

In bootloader:
fastboot boot twrp.img

To flash:
fastboot flash recovery_a twrp.img
fastboot flash recovery_b twrp.img

This is pretty basic.

    Hey, installed your ROM and I have to say it's great, with regards to customization, battery life and all, snappy too. Privacy and security wise, how's it compared to something like divestOS? And is there any tips or guides you have for privacy, have just started to degoogle my life :O
    Well. The Vanilla version contains no Google things. You can either use MicroG with the included signature spoof feature or live without MicroG, like I do. You can install F-Droid's Aurora store, if you need Playstore apps.

    I have a few Google e-mail accounts, but I use K9mail to get and send messages. K9 has its own push service that allows you to get emails right away. For Maps, I use Sygic app, which is much much better than Google Maps. It also allows you to download maps on your storage, so when you use the app, it is done without the internet, which is useful, especially when you are roaming.

    SAFETY NET IS SUCCESSFULLY PASSED WITH MAGISK 24.3. 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:

    Code:
    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):

    Code:
    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

    Download rom from post #3

    All subsequent release will be in post #3.

    The rom could be used on locked bootloader (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.


    See some screenshorts:

    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.

    DO NOT UPGRADE TO MAGISK 25. IT DOES NOT WORK ON A BUNCH OF ROMS INCLUDING JAGUAR. FOR SOME REASON MAGISK DEVS CONSISTENTLY CLOSE WITHOUT RESOLVING THE ISSUE WHERE MAGISK 25 MANAGER STICKS ON LOGO. MAGISK 24.3 DOES THE JOB PERFECTLY.

    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.

    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.
