Getting only 4 hrs of battery life in OnePlus 6t..
That means nothing in of itself. If your phone sleeps when screen is off, which it does in Jaguar, the rest is up to your apps, usage and battery capacity, which is probably around 70% now (3 years since new).

Example: if your signal (in About Phone/Simstatus) is higher then -98db, then your radio will work harder trying to communicate with the nearest tower. If an app syncs often over the internet, you'll get more usage, If GPS, WIFI, Bluetooth are always on, they'll get more battery juice.

I recommend going through settings for each app like WiFi and networks and battery background restrictions. Like a file explorer doesn't need access to wifi to use it or running in the background unless I'm using it. If you have root I recommend installing servicely for dosing the device wile it's asleep

Hi there!

Having a bootloop trying to update to latest rel.

Does it has new 10.3.10 as oos base?

I'm following those steps:
-disable pin

-flash rom
-flash recovery
-flash magisk
-reboot recovery
-flash magisk
-reboot system
-loop

Any advice here? Anyone else with same issue?

Thanks!

Still no luck.

Getting bootloop both with dirty and clean flash.

One question: which oos are you using as base? 10.3.9?
You may need to format data, especially if you're coming from a different rom.

The instructions I provided will work updating Jaguar 7.x to Jaguar 8.

If coming from another rom:
Flash rom
Flash recovery.
Reboot Recovery.
Flash gapps (optional)
Format data. (This wipes your internal storage)
Reboot system.
Set up.
Reboot Recovery.
Flash magisk if you want root.
Reboot system.

Hope it helps.😀

Thank you for your help, but as I wrote I am having bootloop even with full wipe & clean flash.

What I would like to know is: everyone else updated without issues?
Also, which oos base are you guys using? 10.3.9 or 10.3.8 or 10.3.10?

Weird updating to v8 would not boot for me either. I had a copy of lineage downloaded which I had to use to get the phone running. Lost all data in the process?
You didn't need LineageOS at all to make the phone boot.

The reason you couldn't boot was Magisk. Switching between different versions of Magisk requires running of Magisk-Uninstall for the existing version first.

Have you changed Vendor between upgrades?

There are clearly users who had no problems upgrading from V-7 to V-8.
Yeah, that's what I think is the issue, that why I asked if people successfully upgrading have been using oos 10.3.10 as base.

Can i ask you if I should use 10.3.10 as vendor or 10.3.9?

So far I had no lick with 10.3.9 and 10.3.8

    For users who doubt that one can lock bootloader on Jaguar and have absolutely no warning, here is the video:

    does it boot with 10.3.11? now?
    any plans of trying out A12 beta 1? :D
    just asking... but it would be awesome :p
    A11 is done.
    It boots fine with 10.3.11. Actually, you don't even need to erase data when upgrading firmware, as long as you don't boot into system. Just flash stock, TWRP installer; reboot inTWRP and flash stock and TWRP installer again; then flash Jaguar and TWRP installer; then reboot into TWRP and flash Jaguar and TWRP installer again. Then reboot.

    Jaguar won't accept data from another rom, so, your data partition is untouched during stock flashing.

    > Settings to automatically reboot the phone
    Man, sweet. Thank you for this.
    Maybe you are able to make setting to wipe phone after N incorrect password attempts?
    I think it's already included in Android. After certain amount of attempts, there will be a cool down period. After more attempts, the phone will reboot. And after even more attempts, Android will start a count down to wipe, and eventually, it will. I just don't remember the exact numbers.

    Fingerprint enrollment now is fully working.


    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 with no warning screen whatsoever, and with or without Magisk (your choice). It boots like OOS: Android logo and Boot animation. If you want locked bootloader, contact me privately.

    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

    The rom requires the latest OOS vendor in both slots!

    Instructions for Unlocked Bootloader

    1. If you are encrypted on Android Q or lower, you must do a factory reset in TWRP, the option, where you enter 'Yes' to confirm. Otherwise, just wipe data partition.

    2. Reboot into TWRP (after factory reset), transfer Jaguar, TWRP installer and Magisk to internal SD

    3. Flash the rom. Don't reboot!

    4. Flash TWRP official latest installer (not the raw TWRP image). Reboot once. After that do optional flashing such as GAPPS and Magisk


    Keep in mind, the rom has a per app sensor access, which by default is set to 'deny all'. So, if any of your favorite spying apps F/C on first use, go to Settings and enable sensor access for those apps.

    If you want locked bootloader
