[OnePlus 8T Questions & Answers] kllrrr:
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://xdaforums.com/t/op8t-oos-kb...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://xdaforums.com/t/oneplus-8t-rom-ota-oxygen-os-repo-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.

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.
[OnePlus 8T Questions & Answers] OniAraAra:
Been a while since I replied to this thread. In my original post there is a guide on how to restore original HOS:

https://xdaforums.com/t/oneplus-8t-...ogenos-google-apps-theme-ota-updates.4199011/

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.
[OnePlus 8T Questions & Answers] kllrrr:
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?
[OnePlus 8T Questions & Answers] OniAraAra:
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.
[OnePlus 8T Questions & Answers] kllrrr:
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..
[OnePlus 8T Questions & Answers] OniAraAra:
You will want to install these drivers:

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://xdaforums.com/t/oneplus-8t-...ogenos-google-apps-theme-ota-updates.4199011/

(Under "Now make sure your phone is ready")
[OnePlus 8T Questions & Answers] kllrrr:
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?

Has anyone ever installed LinageOS on a Oneplus 8t Cyberpunk 2077 edition? Does that work?

Oneplus 8t Cyberpunk 2077 is KB2000. According to https://wiki.lineageos.org/devices/kebab/ it should work.
[OnePlus 8T Questions & Answers] tipius:
A couple of questions . What for? And what 's wrong with the native ?
[OnePlus 8T Questions & Answers] capo42:
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.
[OnePlus 8T Questions & Answers] tipius:
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.
[OnePlus 8T Questions & Answers] capo42:
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.
[OnePlus 8T Questions & Answers] tipius:
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
[OnePlus 8T Questions & Answers] capo42:
What OS? OxygenOS oder HydrogenOS?
[OnePlus 8T Questions & Answers] tipius:
Oxygen OS 11/0/12/12 KB 05BA
[OnePlus 8T Questions & Answers] ULTRAJC:
Using KB2000 cyberpunk edition over a year, got every OTA(KB05AA/KB05BA both can), and you can download full update.zip to update. there must be some big misunderstanding here.
[OnePlus 8T Questions & Answers] Miguelsr117:
Can you explain to me how you managed to port it to oxygenOS and keep the cyberpunk theme and OTA updates?
[OnePlus 8T Questions & Answers] ULTRAJC:
Flash or dd oem_cust1.img(to both slot) from Hydrogen OS, reboot, that's it.

Start reading this thread from page 1, there is a discussion of how to do everything and the final way that works for everyone.I was helping a guy from Italy to go through the points. If necessary, I can give you a brief excerpt on the points. The moment of this help, it is in Italian, and even through a Google translator. But the friend was pleased, because he did everything according to this instruction. Even taking into account the transcription of one language into another :cool:

You don't need to use Hydrogen OS for a second.
[OnePlus 8T Questions & Answers] Genshikan:
Hello good day i know this might sound noobish and i am relatively new to this so i bought a oneplus 8t cyberpunk with HoS and i want to get the OOS version with the cyberpunk theme and im currently even now have an issue installing this MSM tool an assistance would be greatly appreciated thank you
[OnePlus 8T Questions & Answers] Rootk1t:
You can update to OOS via local upgrade option.

Preserving cyberpunk theme is possible, though not very straightforward.
[OnePlus 8T Questions & Answers] R3pl0id:
Well, after the update to Android 12 it seems that we'll need to do some research again.

I've repeated the same steps but extracting the oem_cust1.img from the latest Color OS build (C.17).

The result looks like this, but the text is a white mess and it's buggy amongst many apps.

The app drawer, notification & ringtone sounds, boot animation, camera effects all are looking good and working fine.

It seems that the ColorOS notification drawer is totally different than the OxygenOS, and that is probably the main reason for this weird behavior, does anyone know if there's an easy way to port the notification drawer from ColorOS to OxygenOS?
[OnePlus 8T Questions & Answers] alfoph:
The recent OOS 12 messed up all the Cyberpunk Theme.. 😓😢
[OnePlus 8T Questions & Answers] g4seb:
Hi, same problem here with OxygenOS12 EU. I'm lost all m'y cyberpunk theme....

If you a have a solution please.

In the past i'm doing cust1 mod. But now i don't know ...

@R3pl0id : do you found a solution ?
[OnePlus 8T Questions & Answers] g4seb:
I use payload dumper to extract payload.bin from New coloros 12 to try to have cyberpunk theme on my original cyberpunk 8t.

But i can't see oem_cust on payload_output ???....
[OnePlus 8T Questions & Answers] R3pl0id:
No solution so far, to get the oem_cust you need to get the ColorOS payload, the OOS one won't have it.

@g4seb

I was able to get the charging animation from ColorOS 12, by running the msm tool to OxygenOS and updating it with the OOS 12 right afterwards(do not flash the oem_cust1, it was probably kept on a secondary partition). But the UI issue remains the same, the real issue is that the new ColorOS 12 notification/quick action bar is totally different from the OOS version, I dunno how to port that over, as this is out of my knowledge level.
[OnePlus 8T Questions & Answers] g4seb:
@R3pl0id : where could i download thé good color OS ?

In fact, what is exactly the problem? Just notification center ? No possibility to change the color of text ?
[OnePlus 8T Questions & Answers] R3pl0id:
Here's the official link to ColorOS 12 C.21

https://component-ota-afs.coloros.com/component-ota/22/04/08/c65e4c7cfe4a4ef6a26f0714132498fb.zip

Yup, the notification center is all blanked out to most apps, also this issue happens on the settings app, I dunno if there's an easy way to change the color text, but if you know any solutions that could be helpful.
[OnePlus 8T Questions & Answers] g4seb:
Thanks for link. And After you just use payload dumper and it's ok ?

In accessibilty you Can put color correction...or perhaps with substratum ??

To have full cyberpunk, you just flash oem_cust ?
[OnePlus 8T Questions & Answers] alkand:
And the Cyberpunk theme itself has been updated to Android 12 in the case of ColorOS? In China, after all, OnePlus has replaced HydrogenOS with it, and you might think that compatibility has become better. But I also lost almost all the Cyberpunk design when upgrading to OOS 12, only the Samurai wallpaper in the screensaver remained.
[OnePlus 8T Questions & Answers] g4seb:
@R3pl0id : Always same problem ? Or do you found a solution ?
[OnePlus 8T Questions & Answers] Rootk1t:
As stated here cyberpunk customization data is on another partition on ColorOS 12.
[OnePlus 8T Questions & Answers] R3pl0id:
It didn't change the partition, oem_cust is still present in the ColorOS zip, and the partition is there, whoever said that has no idea of what they're talking about.

This is the themeinfo.xml file, that informs which apps will have the cyberpunk flag on them, some of them could be shared between OxygenOS and ColorOS, but to be more specific the one that is broken is the com.android.systemui from OOS, that APK is totally different from the one on ColorOS which features the new theme version. A simple Magisk module porting some of those apps should give us the full customization behavior back to OOS.
[OnePlus 8T Questions & Answers] Atul Menon:
Is that shipped pack or add on like one, if so could you backup it and send
[OnePlus 8T Questions & Answers] BillyTheBug:
Hi, has anyone found a solution?
[OnePlus 8T Questions & Answers] BillyTheBug:
FYI, under OxygenOS 13, this morning updated to KB2003_11_F.15. Result I have the Cyberpunk theme with the BootLoader, icones, animations and media. Only missing the charging animation.
[OnePlus 8T Questions & Answers] g4seb:
Hi, really ? Good news. Notifications too ? All are working ? Actually I'm on OS11. So what is the best solution for me to upgrade it ?
[OnePlus 8T Questions & Answers] BillyTheBug:
Yes. I'm very surprised too. Recently I reinstalled HOS to put back the Cyberpunk theme then I switched to OOS11 before switching to OOS12 where I had lost everything. But after this morning's update everything is back, except the charging animation and the dominant color that you have to set manually.
[OnePlus 8T Questions & Answers] g4seb:
Exactly. In oos12 i Lost all animation too. So i put oos11 to have it. Now, did i upgrade or not...that's the question.
[OnePlus 8T Questions & Answers] OniAraAra:
Sorry for the incredibly late response. Awhile back they issued an update that changed the device from HydrogenOS to ColorOS. I have been using ColorOS 12 without issue and I'll be updating to ColorOS 13 tonight. Will share results.

Edit: Works as usual... Had to re-apply theme through settings, but otherwise fine.

Avoided using OOS for this reason, which is why I gave instructions to revert back to HOS.

It does look like people that used OOS found ways around it, but I've stuck with HOS (now ColorOS) since I got the MSM.
[OnePlus 8T Questions & Answers] R3pl0id:
Yeah, with the latest F.17(ColorOS) on F.15(OxygenOS), the theme is functional, a shame that the way that OnePlus implemented it, it only works in the non-dark mode, which kinda messes up with some stuff for me, but it's better than nothing.

Charging animation works on my end, as noted by the last screenshot.
[OnePlus 8T Questions & Answers] BillyTheBug:
Are you on COS or on OOS ?

I'm on OSS and my notification centrer don't look like you.

For the Charging animation, it's the animation of COS not the Cyberpunk Original.
[OnePlus 8T Questions & Answers] R3pl0id:
Using OOS 13.F15, about the charging animation, it's the same present in COS 13 Cyberpunk theme, it doesn't have the older one, the one from HOS 11 is long gone.
[OnePlus 8T Questions & Answers] BillyTheBug:
OK, thank you. I'm using 13.F15 too and my notification center is not like yours.
[OnePlus 8T Questions & Answers] R3pl0id:
You have to use the oem_cust1.img from COS 13.F17, that should fix it.
[OnePlus 8T Questions & Answers] BillyTheBug:
Thanks, have you a link and a tutorial ?
[OnePlus 8T Questions & Answers] BillyTheBug:
Do I have to go back to HOS, update to COS to recover the ROM, and extract the oem_cust1.img ? But then what should i do ?
[OnePlus 8T Questions & Answers] BillyTheBug:
can someone help me?
[OnePlus 8T Questions & Answers] R3pl0id:
Just download the ColorOS latest version from the official link, and use a payload.bin extractor.

After that it's the same steps from before, but use the oem_cust1.img from the extracted payload.
[OnePlus 8T Questions & Answers] BillyTheBug:
Thanks.

For the extraction I think I can do it, but what should I do with the file afterwards?
[OnePlus 8T Questions & Answers] R3pl0id:
Just edited my post from before, I've sent it incomplete by mistake, but it's pretty much the same thing, flash it to the 2 oem_cust partitions and you're good to go.
[OnePlus 8T Questions & Answers] hustlerop:
Can't i use this theme on oxygen os14??
[OnePlus 8T Questions & Answers] shadww:
This is interesting.

Doing local update change slot? if so, and if cyberpunk elements is on slot A for example, if I do local OTA full update on HOS it will change slot to B and I will lose cyberpunk, even though I flashed HOS?

In my experience, flashing HOS upgrade while I was on HOS still retained the cyberpunk update....

Now I am wondering if me flashing another HOS on top of the original shipped HOS, somehow ended putting cyberpunk elements on both slots too. If so this will confirm why I had the theme elements at (1) MSM HSO revert, (2) MSM EU OOS revert, and (3) EU FULL OTA OOS upgrade.

Do you know the path where these elements are saved, and if I can check files on both slots from adb or fastboot (sorry have no idea if this can be done)?

Edit:

I checked my active slot in fastboot using "fastboot getvar current-slot". Current active slot: b

I have all cyberpunk elements, but I noticed I am missing the clock widget. (clock on lockscreen is still cyberpunk)

Hmm I was hoping the full ROM could be installed via local update since it's not just the OTA but the full ROM.
[OnePlus 8T Questions & Answers] OniAraAra:
The MSM download tool is the full ROM, unlike an incremental. The current version is available. You will lose all data using the MSM download tool.

I haven't tried the local updating, as I went back to Hydrogen. I believe you'll be faced with the bootloop if you do it, though.

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!
[OnePlus 8T Questions & Answers] Huguin00:
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~

Have you try the following module :

Download file - GApps_Plus-9.0_A11-signed.zip

devdrive.cloud
[OnePlus 8T Questions & Answers] OniAraAra:
Seems to add everything but the Play Store.
[OnePlus 8T Questions & Answers] shadww:
Gratz!! I think the trick is updating HOS to the next HOS version, which apparently ensures Cyberpunk elements to be installed on both slot a and b.

And, probably after doing that bootloop fixed when doing global OTA because the elements are now available? (this is my theory for now)

If this is true, this probably will secure future OTA updates.

A list of applications that would be considered bloatware on HydrogenOS:

https://pastebin.com/raw/XeTV3Tci

(Omit the lines for essential applications, i.e. phone/widget)

I PMed you and we can talk more extensively, but:

Google Apps works, for the most part (minus some specific features)

Launcher crashes repetitively on startup

MIUI bloatware/garbage

Multiple phone/contact applications

If we can get a module that only installs the bare essentials and persists on updates, then we'd be set.
[OnePlus 8T Questions & Answers] OniAraAra:
I'm only using T-mobile, but Hydrogen has been working fine for me.

Steve0007 has the best solution so far, so I'd imagine if the module he has works, we've got a good solution (for HydrogenOS). Personally, I think this is the best way as there is very little suggesting Oneplus will support this phone on KB05AA.
[OnePlus 8T Questions & Answers] Arr6:
Where are you located? Are you getting Play services?

Currently the phone works perfectly on oxygen OS AA with US T Mobile. I am getting 5g on both sims and Play services.

I hear most of the Hydrogen OS native apps are in Chinese which is why I am hesitant going that route, plus I need play services
