Asking questions like that is liable to piss someone off. Asking ETA's is not just in bad taste it's prohibited on XDA. Be thankful for what we've got.
It's just a question, calm your pants. I have been using XDA a long time, far longer than this account has existed, I have donated to the dev of this rom and I have been releasing my own unofficial build of a rom
the dev has previously stated their intentions to update so I was just hoping they could share a bit more information.

Also, the dev saw my question and ignored it, I chose to not ask the question again or try to bring it to the devs attention, I was happy with them just ignoring my question, you didn't need to bring this old comment back up again

I've been on XDA since honeycomb. Forgive me, I didn't realize I was in the presence of an XDA legend to whom the rules clearly do not apply. Since there isn't a written or unwritten rule about what comments can or cannot be replied to, I will continue taking my liberty, but thank you for your....input

yes, a legend, I am happy with that
the way you spoke to me previously was as if I had not ever used this website before and also assuming that I am not grateful for what is shared here on XDA
but clearly as someone who has donated to this project I have gone far beyond the contributions and thanks of most users who simply download the things without even making an account

You will also find me answering questions and trying to be helpful, contributing in other ways as well

If you are updating from a previous release, you should already have TWRP 3.5.2 in both slots, as you were supposed to flash TWRP installer right after the rom. So, flash the rom, flash TWRP installer, then you can proceed to step 3.
@optimumpro did exactly as you instructed.

NOTE: downloaded ROM again to exclude possibly corrupted zip.

1 Flash ROM
2 Flash TWRP
3 Reboot TWRP
4 Reboot SYSTEM

But instead of booting into ROM, it boots 2x on android logo, then back to TWRP.

You should flash the rom 2 times to make sure it's flashed to both slots because of the A/B partitioning

Since you have deviated from install instructions, possibly jumped to another rom and switched slots multiple times, you may need a fresh install with factory reset.

There is one more thing you should try: if you were trying to switch to Android 12 or 13 roms, your vendor partition on another slot was overridden. Jaguar does not touch vendor (it is stock). If that's the case, then boot into another slot that has normally booting Jaguar, use TWRP to back up vendor (not vendor image). Then reboot into twrp and restore vendor once, then within twrp switch to another slot and restore vendor again. That should fix vendor on another slot.

Well I booted back to previously working slot after 1st failure, also Jaguar ROM from October.
This is 3rd upgrade after August one of Jaguar ROM, no other ROMs on either of the partitions, nor I flashed anything other than this ROM.
So really do not know what went wrong, unfortunately, logcat from PC fetches nothing when logging it from PC on failed boot after upgrade.

As I have said: back up Vendor (not image) from the working slot with TWRP, then restore it to the non-working slot. The fact that you are not having bootloop, but rather booting straight into TWRP is an indication that something is wrong with Vendor on non-working slot.

@optimumpro, is SELinux Permissive compiled in kernel with always enforcing config? I would like to use V4AFX, and it needs permissive. Asking if it makes sense to install permissive magisk addon.

EDIT: much simpler way:

Hi Optimumpro,

The download hash for V27 Vanilla LINK says:
f417f58cc0cee11ca2ace95011d0cc1f

But when I check the MD5 hash after downloaded, I am getting:
A0508BE4453B9EC8D5BA927D271B01CB

Does that MD5 hash in the download LINK refer to your original uploaded hash for the Vanilla V27 ZIP file??


Thanks again for keeping Jaguar alive for Oneplus 6/6T phones!

The a0508be4453b9ec8d5ba927d271b01cb for JaguarOneplus6T_V27-VANILLA.zip is the correct one. You have the right file. XDA is probably using a different algorithm. Mine is MD5.

Thanks for confirming the hash matches yours.

I noticed that both the Vanilla and Full download links have the same MD5 per V25, V26 and V27 -- I have not downloaded FULL, but I am guessing that those are the hashes of the FULL version?

    Hi Optimumpro,

    Could you kindly please also upload the new January V28 release to XDA or Androidhosting? Because when I click google drive, I keep getting a blank page.

    The MD5 from the previous release matched to yours last time I asked about it, so it should not be a problem if XDA displays their own hash in the download link.

    ...

    And sorry for the late reply to your earlier question, I post on the OP6 thread too because I also own a OP6. :D

    Thanks again for keeping this ROM alive for OP6/T users!

    ...

    Just found out from another post that Androidhosting is going out of business?! Perhaps you can upload to Mega.NZ ??? They are quite reliable with fast download speeds.
    XDA upload works in 1 out of 100 tries. AFH isn't working at all. Google drive is working fine. So, switch to incognito mode or try another browser.

    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).

    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 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 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. If you are encrypted on Android Q, or lower or any stock, 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 3.5.2 (after factory reset), transfer Jaguar, TWRP installer and Magisk to internal SD

    3. Flash the rom. Don't reboot!

    4. Flash TWRP 3.5.2 official installer (not the raw TWRP image). Reboot once. After that do optional flashing such as GAPPS and Magisk

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

    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:
    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 use fastboot or mess with partitions without triggering 'device corrupted' warning.


    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.
