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

VERSION 19 FIXES SAFETYNET PASSING (WITH MAGISK 24.3)
See detailed instructions here

You can actually use alarm when the phone is OFF. It would boot 2 minutes before 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 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 23. You don't have to flash it, just install the attached Magisk.apk.

Bugs: AOD working, but no info shown on lockscreen (works fine on other Onepluses)

Install instructions

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 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) as a normal app.

PICO Gapps has been tested successfully with this rom.

All downloads are in post #3.

All subsequent releases will be 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 your DRM L1 certificate back. Most banking apps (if not all) will work with or without Magisk: you cimply get a warning 'your devices is rooted', but you can proceed to login

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.

Also, see some screenshots attached:

Ohhhh this is something new. I have one app what is not possible to use it with unlocked bootloader. At this moment I'm on crDroid. What I need to do if I want be on this ROM with locked bootloader? Should I flash stock before that?

 

[krkhaha]

But on locked bootloader that will be possible to manage kernel and flash some custom Kernel?

"I have one app what is not possible to use it with unlocked bootloader"

I am not sure what you mean. Locked bootloader doesn't affect apps, which you are free to install or uninstall.

You don't need to be on stock. You need to flash Jaguar, boot it and then you contact me: you'll get instructions and one additional file to flash. After that, you just relock.

 

[optimumpro]

But on locked bootloader that will be possible to manage kernel and flash some custom Kernel?

No way! You can't touch System, Recovery, Boot and Vendor partitions without unlocking. This is why Magisk is prebuilt and requires only Magisk manager to have root. But you can flash Gapps on locked bootloader.

 

[krkhaha]

Can you write about gapps? What exactly is in?

 

[optimumpro]

"I have one app what is not possible to use it with unlocked bootloader"

[krkhaha]

Safety net is passed. I have information on screen of app my bootloader is unlocked. Some banking app can work and some is not possible even when safety net is passed and is hided in magisk hide. I know now magisk hide don't work but I checked that long time ago. I have 2 banks what can't work on unlocked bootloader.

 

[optimumpro]

Can you write about gapps? What exactly is in?

If you meant Kernel manager apps, yes, you can use them on locked bootloader, as they don't modify kernel, just send commands.

Gapps. Gapps could be flashed by users like on unlocked bootloader.

The rom has the hush signature that represents the sum of Vendor/Boot and Recovery partitions. So, any change to those partitions, except when you upgrade Jaguar, would result in 'your device is corrupt and can't boot' message.

 

[krkhaha]

Have you got some screenshots from additional settings? Okay I will try in the free time. At this moment I work all the time. Sounds good.

 

[krkhaha]

Ona bad thing is not possible to manage kernel in app I have a lot settings. And is not possible to use kona heh... You know.... From long time on radioactive mod kernel with my own settings. But with unlocked bootloader will be possible to manage kernel in app.

 

[optimumpro]

Ona bad thing is not possible to manage kernel in app I have a lot settings. And is not possible to use kona heh... You know.... From long time on radioactive mod kernel with my own settings. But with unlocked bootloader will be possible to manage kernel in app.

No. You CAN use kernel managers, as they don't modify kernel. They just issue commands.

But you can't flash another kernel.

How can I install it on Oneplus 8 TMO?, I have to unlock my bootloader install the room and relock it again?

How can I install it on Oneplus 8 TMO?, I have to unlock my bootloader install the room and relock it again?

Have you ever installed a custom rom on your TMO's Oneplus 8?

 

[acostmisa]

Have you ever installed a custom rom on your TMO's Oneplus 8?

yes, as you said that can be used with locked boot loader so i wanted to know if i have to unlock it, flash and relock.

 

[optimumpro]

yes, as you said that can be used with locked boot loader so i wanted to know if i have to unlock it, flash and relock.

OK. As it says above, it's a donate feature. You need instructions and additional file to flash, then you can relock. Contact me via PM.

Edit: And No, you don't have to be on stock to relock.
