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

VERSION 19 FIXES SAFETYNET ISSUES WHEN USING MAGISK 24.3
See complete 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 build of 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 or Oneplus 8 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.

14. Prebuilt Magisk. You don't have to flash it, just install the attached Magisk.apk.

Install instructions:

If this is your first time coming from stock to a custom rom, you MUST have Android 11 stock in both slots. So, either have a few stock updates over the air (to populate the second slot) or flash stock rom with TWRP. Downgrade, if necessary.

1. Install Jaguar recovery 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

2. Download the rom on 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, DO NOT FLASH MAGISK ZIP, just install Magisk manager (apk) as a normal app.

All downloads are in post #3

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:

Get back your DRM L1 certificate. Most banking apps will work regardless of Magisk.

Security: 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.

Why prebuilt Magisk? Because you can't modify kernel or recovery on locked bootloader post installation, and that's exactly what Magisk does.

See attached som screenshots:

If downloading from XDA, always use your browser in private mode

For Indian Users Only: If you don't have 5G, that means that you have an older handset and Indian carriers didn't provide their modem configuration to Oneplus in time. In this case, use QPST method which has been confirmed working

[CDI-78]

Gonna try !

 

[CDI-78]

System navigation don't work,

 

[optimumpro]

System navigation don't work,

Everything works fine. You just need to toggle back and forth navbar in Settings/RomContro/Navigation bar. As far as the rest, you can switch to 2, 3 buttons or Gesture navigation.

Also, it would make sense to search for settings first. For example, type 'Gestures' in Settings/Search, and you'll get about 10 different settings.

You can do edge gestures. You can pick out of variety of actions to assign to edge gestures including 'kill app' etc.

 

[CDI-78]

That's what i've done,
Flash twice, whithout gapps, and with open gapps,
Try to enable 3 gestures, navigation bar, switch, reboot,
Nothing to do, will try again later,
Thx.

I just checked on my Oneplus 8: everything switches fine without reboot. Also, my Kebab tester didn't mention he couldn't switch between buttons and gestures.

Actually, this is what the tester initially said:

Also, with gesture nav enabled, occasionally the go home (swipe up from gesture nav pill) stops working. The swipe from edge to go back will work still, but swiping up to try to go home doesn't do anything. No haptic feedback, no anything.

However, when I told him about additional settings that he can configure even the sensitivity of edge gestures separately on the left and right, and enable haptic feedback, everything became normal. So, clearly he could switch between gestures and buttons.

Did you do factory reset aftery initial flashing? You also need factory reset after installing Gapps for the first time.

 

[CDI-78]

I usually factory reset before flashing,
Will come back on this rom on thursday, maybe tomorow in the evening.

 

[phabet]

pls. add single tap feature (oneplus settings), rom is very smooth, i like it

[nujackk]

Ok couple quick questions.
With locking the bootloader magisk will still work as usual?
Which webview alt do you recommend? And why? (Haven't heard of the vanadium until now and quick look makes it seem like might not have some functionality outside of graphene os)

Yes. Magisk is already in kernel. You just need to install Magisk manager as a normal app, and you have root. So, there is no need to flash it. In fact, if you flash Magisk on locked bootloader, you won't boot.

Just because Graphene's developer says no use outside of Graphene doesn't make it so. I have no Googleplay on my phone and use Vanadium on Jaguar with zero issues. But Vanadium is known for blocking some Google servers, which breaks account registration. So, for users who want Gapps etc, it's Bromite, which is enabled by default.

 

[optimumpro]

The reason there is no single tap is to prevent false positive screen wake-ups, when the phone is in your pocket or from other accidental touches.

Thank you, that is exactly info i need. I won't install this till weekend when i have more time to tinker. But I'm assuming there is way to do the donation and activate the features in the rom?

But of course: either PM or there is a clickable option in Settings/System.

 

[Daystars]

How do you install gapps with your rom? I keep getting not enough space errors when I try.
Using TWRP, then adb sideload from recovery.

 

[optimumpro]

How do you install gapps with your rom? I keep getting not enough space errors when I try.

As I said in another Oneplus 8 thread, the whole rom is optimized for performance, not size. It is also heavily deodexed for the same purpose. If a normal system app has 20mb, deodexed, when odexed, it will grow into 60mb. So, it is possible that System partition doesn't have enough space.

A release with reworked partition sizes is coming. For now use PICO Gapps. After installation, you can add items you like from Playstore, which will go to Data partition that has plenty of space.

 

[hightech316]

Can't wait to try this ROM.

All the extra hardening and security are a important and unique feature .

I have noticed on the screenshots at displays relock bootloader, how does that exactly work? A script ? run the fastboot commands needed to lock the bootloader?

Thanks for the release
