Can I install it from 11.0.9.9 ? What do I need to do if I want to go back from this beta? My phone is locked bootloader and no TWRP or root is installed

From different resource:
⚠️⚠️⚠️ WARNING ⚠️⚠️⚠️

DO NOT FLASH CLOSED BETA 2 LEAKED BUILD OF COLOR OS 12.

IT JUST COMPLETELY BRICKED MY PHONE AND NOT EVEN EDL IS DETECTING IT NOW.

I HAVE NO IDEA IF IT AFFECTS ALL DEVICES BUT THOSE WHO HAD SIM ISSUES ON CBT1 SHOULD AVOID IT AT ALL COSTS

Some people are getting their devices bricked cuz they are flashing. Don't do a flash just local upgrade it and youl be fine.

I upgrade my oneplus 8 pro directly from Oxygen os 11 11.0.9.9 via local upgrade .. I'm already lost my fingerprint but my problem is I have no coverage on both my Sim Card.. know My pc doesn't recognize my phone when in fastboot mode .. and the Sim fix only working when the bootloader is unlocked.. any help?

Don't try simfix. I have seen people killing their phones on cbt 2 while people who dont use simfix are currently using cbt 2 just fine.

Use this Oxygen OS System Updater App on the Color OS CBT 02 to update to CBT 04

As always put the latest firmware .zip into the root folder of the internal storage and flash normally, after the reboot you are updated.

To downgrade we will probably have to wait for a specific rollback firmware from Color OS 12 to Hydrogen OS, as the partition layout is different I guess.

As usual, patience.

Flashed Closed Beta 2 directly from stable OOS 11.0.9.9 without issues or Data loss.

(I only had to flash sim fix since I had no cellular signal issue, used the SIM FIX in OP) (Needs to be flashed in fastbootD) when in bootloader mode on windows shell type ' fastboot reboot fastboot '
Then run SIM FIX .bat

IMPORTANT! Backup persist before doing anything just in case!
•open terminal app
•type ' su ' (to get root access)
•then type ' dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img '
•copy the file named persist.img to your desktop or somewhere safe.


Now download Closed Beta 2 and place it in your internal memory and do a local update.

if you get any errors or stuff here's the link to MSM TOOL for reverting back to Android 11 OxygenOS.

For me everything works fine, FOD, SIM, Bluetooth everything. Literally a daily driver. It feels like oxygen but with a lot more customizations.

Do you hear any hardware noise when switching to camera or gallery? I read people have this issue. How is the battery life so far?

    I just quick test OpenBeta C10.
    I can not root , went back to OOS now.
    You can root it by extracting boot.img from the firmware archive with the help of payload dumper and patching the file with Magisk manually. Then you can flash it in fastboot mode.

    Thanks a lot for your reply and feedback, much appreciated. From what i have saw, i think ill stay on OOS11 at least until Open Betas are available. Really want to try ColorOS but i preffer and love stability haha.
    U may give it a try.
    But here are things to warn about :
    1- C.08 on 8 pro is broken. U cant use FOD. (C.07 works)
    2- notifications on AOD are not displayed neither the edge lightning.
    3- apps got killed after a while. Unless u disable battery optimization and lock them in recent apps.
    4- chat bubble doesn't work.
    5- sometimes u cant replay from notification.
    6- no google assistant as their assistant take place everywhere.
    7- some apps are in Chinese language even theme store which is annoying.
    8- u cant apply installed external livewallpaper.
    9- low volume on calls (just slightly than OOS)
    +-------
    Now for the good things
    1-Vibration feels great and mostly in everything.
    2- battery for me is better than OoS.
    3 - flaoting window is awsome.
    4- FOD on C.07 is so fast and better animation and sounds.
    5- overall animations are better.
    6- Dark mode with light and grey and pitch black also with wallpaper snd screen dim.
    7- better AOD themes and auto brightness. Also rise to wake is good.
    .............
    Some other things i might forget
    As a daily driver its good if u dont mind disabling FOD.
    Give it a try ;) u can always go back to OOS

    Can someone provide me cbt7 boot img and vbmeta img

    I have pulled the ones from cbt7 for the 8 Pro. I have attached the original, patched (with latest Canary) and VB Meta for those that want it. As always, just boot the patched and patch your own. Tested and working fine.

    Reminder, the command for disabling vb meta is:

    In Windows:
    fastboot.exe --disable-verity --disable-verification flash vbmeta vbmeta.img

    In Linux, just leave off the .exe in fastboot name but is same command.

    Edit: If you are referring to a more recent ColorOS 12 CBT version than 07, there has not been a public leak yet that i am aware of.

    Report for C.09 for Oneplsu 8 Pro - IN2020 - Locked BL - OOS 11 11.0.10.10 Global as Base

    Just finish flashing the latest C.09 on my OP 8 Pro, Using as Base OOS11 11.0.10.10 Global, with a locked BL and all my data still on phone, remove my FP and face unlock data, an proceed to a local upgrade, change the name of the ZIP to IN2020 and copy on storage root, till now i havent found anything that is not working properly, the only thing that mess with me was the bunch of chinese stuff that it brings that i have to either uninstall, disable or simply just leave it there because theres nothing to do.

    Animations and the flow in general is awesome, at least i really appreaciate the change comming from OOS. Customization in general is very wide and awesome. Transitions between apps and going home screen, pulling notification drawer....everything feels more smoth in my opinion.

    After the update, proceed to add again the FP and face unlock and both worked awesome, as fast (sometimes faster) than OOS.

    Network for both sims working great, as well as WiFi, Both Cameras works super well also (including gcam), AOD, Notifications are working at least for my apps, have nothing to say, daily driver.

    If you guys have any doubt, ill be daily drivin' this boy for a couple of days, maybe even more

    Here are some SC
