You can use kernel managers, because they don't modify anything, just issue commands, but you can't replace kernel on a locked bootloader. Nor can you replace recovery.Another question, can we use custom kernel Whie locked? Using FKM.
Edit: More specifically: In my view, Franko's tweaks are outdated, no longer applicable to modern processors, and even when they were, degraded performance.

Sorry, was getting phone working again. But on the phone it would say fail with error 7 twice and once said error 1 , only would say reading error in terminal.
I eventually got it to install via ROMInstaller. So I have it up and rnning at this point. Phone is hot but may just have been the extended boot time after the install. I let it settle and see how things are.
It may have just been me, If no one esle complains.

There could be 2 reasons for install error. Corrupt download from AFH, as when I was uploading, it took longer than usual; or increased system image size.
Increased system is highly unlikely, because recovery would have said so - something like 'image larger than actual partition size'. Also, you wouldn't be able to install with other methods, if size was an issue.
I'll probably end up re-uploading the rom.
Yeah took about 10mins on the initial boot.How's the latest update?

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 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:Code:fastboot flash recovery_a recovery.img fastboot flash recovery_b recovery img
Code:adb sideload 'name of the rom'
Download rom V-13: Rom Downloads in post #3

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 releaseThe 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:
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:Ok , looking over our thread on the 8. Not sure at what point i can install gapps. I ultimatly want to relock the bootloader after done setting up and testing. But seem like need to lock before installing gapps?
Also any particular gapps package you recoomend?I just tested a few banking apps with Magisk not hidden and locked bootloader. To my surprise, all of them worked. I did get a warning 'your phone is rooted', but there was also an option to 'hide this warning'. After that you could login or open a new account.
What that means is that as long as your bootloader is locked, your banking apps will work regardless of Magisk.
