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

SAFETY NET HAS BEEN FIXED AS OF Version 19 (confirmed)

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

Verizon support with no RTT issues. Call recording button is visible.

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 (my current device). You can check the Oneplus 5 development thread here: Oneplus 5 thread or Oneplus 3 or Oneplus 6 thread here or 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. Kernel has security features ported from linux kernel 4.14.

The rom could be used on locked bootloader (donate feature) with or without Magisk (your choice).

Why not Android 12+?

Every Android version after Android 10 has been a regression in terms of privacy and security. Google has introduced deeply integrated multiple APIs that are available to advertisers. Essentially with these APIs, third party apps have access to System's high level permissions with users completely locked out of any control.

Also, I am not in the habit of posting undercooked releases. In my experience, Android new releases don't become stable until r40+. Why? Ask Google. My take is: their main product is selling user data, so, everything else is on the back burner. Like for soup cans (users) on super-market shelves, Google' s only concern is for the product (you) not to go spoiled before it is sold to its true customers - advertisers.

Some unique Jaguar features;

1. Encryption parameters are different from AOSP, which creates an extra hurdle for adversaries.

2. Filtering of Type-Zero silent SMS (the first thing an adversary would do to check if you are online. The phone silently replies without anything displayed to the user. In Jaguar, the phone does not respond)

3. Toggle to prevent all apps from accessing clipboard (not a simple warning, but the full restriction)

4. Most of kernel symbols are read-only or mostly read-only

5. Ability to relock bootloader (donate feature) while preserving Magisk (root)

Otherwise, and in addition to hardening, the rom has all standard+ features that come with custom roms:

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. Call recording button visible in Dialer and working for all

8. Vanadium Trichrome Webview and Chromium browser

9. All regular customizations with the latest addition of Battery Defender, as well as Aggressive, Extreme battery saving and Smart charging

10. Customized Launcher 3 has extra grid options: 6x7 and 5x8 + an option to change icon size globally

11. Verizon CDMA support

For newest features/changes, see post #3.

The rom requires the latest stable OOS 10 vendor in both slots!

Instructions for Unlocked Bootloader

Update for those who are on OOS 11: to use this rom, you must have the latest OOS 10 in both slots. If you are downgrading from OOS 11, use whatever TWRP you already have (no lower than 3.6) to flash OOS 10 once, then flash TWRP 3.5.2 installer. Boot once, then back to TWRP and flash OOS 10 again for the second slot, then TWRP 3.5.2 installer. Boot again. Now you are ready to flash Jaguar

1. Switching from stock to custom roms requires factory reset via TWRP, the option where you need to enter 'Yes' to confirm. So, do it now.

2. Reboot into TWRP 3.5.2, transfer Jaguar, TWRP 3.5.2 installer and Magisk to internal SD

3. Flash the rom. Don't reboot!

4. Flash TWRP 3.5.2 official installer. Reboot once. After that do optional flashing such as Magisk

The latest release is always in post #3 on top.
