No problem, I downloaded the zip in case I need it down the road so thank you. Hopefully they officially update everything to be easily switched to Oxygen so all these hoops don't need to be jumped through lol
When flashing these files, is the phone itself formatted? In the sense that it will be necessary to restore the content?

Hi,
So I have some good news (I think).

I was trying to flash OxygenOS (Global and EU) on my HydrogenOS (11.0.4.5) Cyberpunk8T. It ended me bricking my device. (Yes, I was fooling around with fastbootd >_<)
I went to this thread: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/
and used the MSM tool @OniAraAra linked: https://androidfilehost.com/?w=files&flid=320230

I was able to get back to HOS (11.0.1.2). So this even downgraded my version, and I had all cyberpunk elements.

Then it hit me. I was trying to figure out how did the sellers flash the global OOS.... and most of xda members here state that their device came on "11.0.4.5.KB05AA ", and it had " SOME Cyberpunk things ".

So I went and did an MSM restore on my Cyberpunk8T HOS (11.0.1.2) to EU OOS 11.0.4.5 (from unbrick-tool thread above). Guess what it worked. I was able to boot to EU OOS 11.0.4.5.

Then right away, I did a local OTA upgrade using full package EU OOS 11.0.5.6 (https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/).

I booted to EU OOS 11.0.5.6, have cyberpunk boot animation, wallpapers, theme, icon pack, and sounds (basically everything, let me know if I should check something specific).


ps: I also heard that local upgrade is not available on Global or India OOS, thats why I tried it on EU. Not sure if one does EU MSM, then flash Global Full OTA locally if that might work or not.


Edit:
Uploading some videos (higher quality might some time to process)
can provide the cyberpunk clock file in the zip that you flashed in your phone

Hi guyz, I need help with my device.

I bought a version with HydrogenOS (as i remember 0.1.2) and tryed to flash it on OxygenOS.

Last thing I done was downloading last firmware for 8t via OxygenUpdater OnePlus8TOxygen_15.E.23_OTA_0230_all_2102011823_d38dd558655966a and flashed it throw Setting > Wheel > Local

This led to a bootloop and I lost possibility to recover, couz recovery mode is no longer load properly ( I see just a black screen without options)

Before that, I unlocked bootloader and tried to do MSM flashing using KB05BA builds from this post https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/
I wasn't able to do that because of Param Preloader issue, wich I face each time. (Tryed different ports, cables, amd and intel, drivers, all steps from this article https://www.droidwin.com/fix-stuck-in-param-preload-error-msm-download-tool/)

After that I tried to flash phone by downloading firmware in the root section and using phone settings. In that way I tried KB05BA Europe 11.0.4.5 and 11.0.5.6 from this post https://forum.xda-developers.com/t/...po-of-oxygen-os-builds.4193183/#post-83971385 but after flashing I recieved a bootloop as well. Hopefully the recavery mode was available.

Now I don't know what to do.
I though to use TWRP, but have some concern about it.

Is TWRP for 8t fit to CP77 edition?
Will I be able to stock recover from it?

Right now I have a brick with unlocked bootloader (((
Could anybody guide me throw that sheet)
Thanks in advance.

This will likely get you back to stock.


Also don't use Oxygen Updater. I tried it early on and it only caused me wasted time and problems.

I am currently on OOS, with all the CP goods, with no problems at all. Also was able to update last night with the latest security OTA and nothing was lost.

Reach out if you need help but read through this entire thread as there is a lot of good info here which will help you work out the best way to manage your new device.

Been a while since I replied to this thread. In my original post there is a guide on how to restore original HOS:

I tried with a clear case. Does not look too bad. I may try again with closer and straighter cuts.

Where'd you find one that fits? The market definitely seems to be short on cases, which makes sense. I'm still using the OEM, but a clear/silicone 8T might work.

Thank you very much for answering!

I tried this thread and some other with MSM using. I still think that MSM flashing is the best option but can not handle the problem with param preload error, I face it on two different laptops (AMD/Intel).


Does anybody know how it works in MSM..
Is it important if device bootloader is unlocked? (As I think, it does not as far as I saw the post, that after flashing phone relocked but who knows..)

May be someone can figure out what is happening by looking at log file..

May be internet speed is important while starting MSM?

May be it is possible to restore recovery mod somehow without MSM?

I do not know about the "param preload" error. Are you clicking "Run as Administrator" when you use the MSM tool? Did you extract the files properly? Have you made sure the device drivers are installed properly?

I do not believe the bootloader being unlocked matters. One thing I recall was that if the bootloader was unlocked, the device would wipe if you went to lock it again.

Sure, I run as admin.
Not sure about extracting and driveres, I'm already confused about different builds and drivers.
Is it important to have Android drivers correctly installed? or for MSM only Qualcome driver is required?

Thank you one more time for help and asistance, I will keep trying..

You will want to install these drivers:
https://oneplususbdrivers.com/oneplus-8t-usb-driver-download/ (Oneplus)
https://androidfilehost.com/?fid=10763459528675593342 (Qualcomm)

Param preload means it isn't even getting to the point it has interfaced with your device. Make sure you follow the instructions here: https://forum.xda-developers.com/t/...ogenos-google-apps-theme-ota-updates.4199011/

(Under "Now make sure your phone is ready")

Thank you @OniAraAra and @gee.dunkin for your assistanse. The problem was with Qualcome driver. I tried different ways and in my case this post https://forums.oneplus.com/threads/...stuck-in-param-preload.1107124/#post-23007581 helped to fix param preload issue (work on intel, didn't try on amd).

Hi, I'm getting a 8T Cyberpunk. How's it on HOS in compared to OOS? (in battery consumption, heat, performance) Does anyone have experience?
Should i flash Europe rom or global?

A couple of questions . What for? And what 's wrong with the native ?
At the moment i have OxygenOS on it. No OTA on that. So i need always to reinstall the whole phone for an update. But i need some apps (RSA for example) that can't be backupped. So i need to contact my company to give me new tokens.
HydrogenOS could work, but i need the OS it in German cos of the Google Assistant.
So i thought LinageOS would be the best fit.

I don't quite understand why to reinstall everything when updating? Or is a permanent root important to you ?But then you can just become a beta tester and use the test version.

In my Knowledge you cant OTA OxygenOS on Cyberpunk edition Phone. Only HydrogenOS.
So reinstalling with the every Security update is a must. Or am i wrong.
And no, has nothing to do with root. I don't even have root enabled.

I've had a Cyberpunk phone for a year now. It works on the European version. And there are no problems with updates. I went through everything in the loader, as previously discussed here. And now I have a normal OS , with themes and cyberpunk downloads

    Update worked, however I need to highlight that 11.0.6.7 seems buggy to me (Stutter and other stuff)

    Ok. So I got Global 11.0.6.7 update (OTA, incremental, around 500 MB size).
    I updated and it worked (with all cyberpunk elements working and nothing changed).

    Proof:

    1) Cyberpunk8T Phone at Global OOS 11.0.5.6, and showing receiving new update under system-update:

    2) Downloading Global OOS 11.0.6.7 update. Not full update, OTA, incremental, around 500 MB size:

    3) Booting to Global OOS 11.0.6.7 after update and restart (it took a bit more time while booting, but worked at the end):

    4) Showing updated phone to Global OOS 11.0.6.7 with cyberpunk elements intact:


    So, I think flashing cyberpunk cust on both slots before, and then relocking and updating did work.
    Below I will put the steps I took (please note that I tried this on Global version, no idea if EU or IN is the same).

    Steps:

    -1) If you received phone on HOS, do full local update into next HOS in order to ensure cust is flashed to the other slot. (preferably do 2 HOS full local updates just to ensure, recommended versions are OnePlus8T_Hydrogen_11.0.4.5_15.H.19_KB05, and OnePlus8T_Hydrogen_11.0.5.6_15.H.20_KB05. (another option would be to flash cust at this stage, but I am just stating what I did personally).

    0) Use MSM tool to convert to Global OOS (check thread and forums for this step)

    1) Now your cyberpunk 8T phone should be on OOS, and you have all cyberpunk elements working (this is important as it points that param flag for cyberpunk is active)

    2) Unlock bootloader and root the phone (credit to @Kihara777 )
    (for full info about this step check https://forum.xda-developers.com/t/...-for-oneplus-8t-devices.4198459/post-84055453 )
    (for root info read https://forum.xda-developers.com/t/...in-eu-us-kb2000-kb2001-kb2003-kb2005.4178675/ )

    2a) download this image: https://1drv.ms/u/s!AsJy8Rcn_wjLhLwuunq7W9seKfKT7Q?e=vTKQd0
    2b) Use below commands in adb to push the cust images (google how to to adb commands).
    Bash:
    adb push H19_OTA-oem_cust1-raw.img /sdcard/oc1.img
    (I actually unziped and copied the file to phone root through windows and renamed it to oc1.img, then did adb shell in cmd, and ran the below commands)
    su
    dd if=/sdcard/oc1.img of=/dev/block/bootdevice/by-name/oem_cust1_a
    dd if=/sdcard/oc1.img of=/dev/block/bootdevice/by-name/oem_cust1_b
    2c) remove root and relock the bootloader (optional)

    [Alternative to step 2 if you cannot root][Tested by @lexcyn Thanks! ]
    2) Unlock bootloader
    2i) download this file: https://1drv.ms/u/s!AsJy8Rcn_wjLhLwtuwnEWCG4E1bNMQ?e=iRf5jm
    2ii) flash through fastboot using these commands
    Bash:
    fastboot flash oem_cust1_a H19_OTA-oem_cust1-sparse.img
    fastboot flash oem_cust1_b H19_OTA-oem_cust1-sparse.img
    2iii) relock the bootloader (optional)


    3) After rebooting the phone, you should have all elements, and OTA incremental updates should not affect your cyberpunk elements or cause bootloop

    This what have worked for me. Please familiarize yourself on how to unbrick just in case things did not go well.


    Edit: fixed OOS 11.0.6.7 video link, and info about the adb commands
    Edit2: flashing cust files using "dd" commands require the phone to be rooted. Alternatively, I added another flash commands using fastboot that not require root.

    I received a Oneplus 8t (Cyberpunk Edition). The phone was supposed to have HydrogenOS as it is a Chinese phone. However, the vendor installed Global OxygenOS (KB05AA). After OTA updates, the phone wouldn't reboot and would get stuck on the Cyberpunk boot animation.

    ________________________________________

    OxygenOS

    I tried updating/restoring OxygenOS using the the MSM download tools here:

    Pros: Google Apps and a Global ROM.
    Cons: No OTA updates and no original Cyberpunk theme.

    Best case scenario for OxygenOS users would be for Oneplus to fix the OTA updates for Cyberpunk phones. This would stop the bootloop problem people are having.

    ________________________________________

    HydrogenOS

    I have made a guide on how to restore HydrogenOS and add Google Apps:

    Pros: Working OTA updates, the original Cyberpunk theme, and Google Apps!
    Cons: A little bit of time and maintenance.

    ________________________________________

    Overall I would highly recommend trying the HydrogenOS solution I've linked above. It works excellent for me, so I won't be pursuing a solution for OxygenOS unless things change. The guide I wrote and linked above should get anyone with a Cyberpunk phone on to HydrogenOS (with OTA updates, original theme, and Google Apps).

    Still stuck at bootloop...
    I have done the following

    MSM to HOS then MSM to OOS (GLOBAL) - local update to newest update full zip (GLOBAL)= bootloop

    MSM to HOS then MSM to OOS (EU) - local update to newest update full zip (EU) = bootloop

    Cyberpunk goodies only work on HOS so far...

    I'm kind of out of ideas, any suggestion?
    Thanks!

    OK, so i finally got Oxygen OS 11.0.5.6.KB05AA (Global/USA) Running on my Oneplus 8T Cyberpunk edition (KB2000) with all the Cyberpunk goodies.. .

    After all the previously mentioned attempts this is what got me through:

    1.- MSM to Hydrogen OS using the link provided at OP.
    2.-- Update Hydrogen OS to 11.0.5.6 using OTA update (incremental update directly on the phone).
    3.- Once Hydrogen complete update to 11.0.5.6. Turn phone OFF.
    4.- MSM to Oxygen OS to 11.0.1.2.
    5.- Once Oxygen OS boot up, loaded 11.0.5.6.KB05AA FULL zip update (Provided on OnePlus website) to the phone's root directory.
    6.- Perform a Local update through the "gear" icon under the system update section.
    7.- voilà!!!

    If you guys have any questions in regards of what i did, feel free to ask me.
    Best of luck~

    So to flash using dd commands, you need to be rooted (sorry I did not notice that at first). See https://forum.xda-developers.com/t/...eplus-8t-devices.4198459/page-5#post-84055453

    However, I think flashing the parse images through fastboot might work without being rooted. if someone want to test that here are the steps:

    i) download this file: https://1drv.ms/u/s!AsJy8Rcn_wjLhLwtuwnEWCG4E1bNMQ?e=iRf5jm
    ii) flash through fastboot using these commands
    Bash:
    fastboot flash oem_cust1_a H19_OTA-oem_cust1-sparse.img
    fastboot flash oem_cust1_b H19_OTA-oem_cust1-sparse.img

    I will update my original post to state that flashing through dd command need root, and add this above info as unconfirmed (until someone can test?)
    Was just going to post this - the other command is if you are rooted.

    This worked for me by the way, THANK YOU.

    I was already on OOS 11.0.5.6 so I:

    1) Unlocked bootloader
    2) Flashed cust to a & b via fastboot
    3) Relocked bootloader
    4) Set up phone and restored from my OnePlus backup
    5) Downloaded / installed OTA

    Worked a treat and still have all of the Cyberpunk goodies!

    [Edit] Also worth mentioning I don't have any of the lag issues on the new update, but probably since I wiped the phone and updated.
