Can you share the img file here?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Brusington:
Yeah, I did all of that. A few times actually because it really wasn't making sense. No luck. I was able to use the batch installer instead and that worked fine.

Hi, the brightness drops/reduces after HDR photo/video viewing. Is there any solution for this or should i restart everytime?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cyriljohn01:
It's a known bug, restarting is the only way to fix it. Best try and avoid HDR for now.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] firoz3321:
Just wondered if there was some work around. Google photos is affecting so can't avoid it. Hdr photos i guess.

Has anyone else had google pay break on the most recent update? I'm not rooted but previously Google pay worked fine, since the update Google pay detects its a custom rom
[OnePlus 8 / 8 Pro & 8T Cross Device Development] 5i1v3rStorm:
Yeah, since we booted once without Magisk the PlayServices detected CustomRom for me as well. So I had to work on that again.

1st: get safetynet to pass. I use UniversalSafetynet Fix by Kdrag0n.

2nd: activate zygisk and enforce the denylist. Deny Google Wallet and Google Play Services.

3rd: clear the AppData of the Playstore, the Play Services and the Google Wallet app.

4th: reboot.

Now you should be able to re-add your cards.

By the way, clearing the appdata if the PlayStore deletes the configuration which apps are NOT to be updated. I didn't realize that and my YouTube Vanced App got overwritten by the crappy advertiser stock YT app.

Edit: after the reboot the play services are not on the denylist anymore for me. It still works, though.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Klusio19:
Use OxygenUpdater from play store

[OnePlus 8 / 8 Pro & 8T Cross Device Development] Asad_970:
Hi, just need help being pointed in the right direction, thanks. 😊

Is this ROM compatible with in2017 i.e. OnePlus 8 TMobile. I'm on official oxygen os 12 for tmobile (if that might be important to note).

I can't figure out how to root this phone, to root I need to downgrade to android 11, to downgrade I need msm tool, but I can't for the life of me get this phone to connect to the msm tool, it won't go into edl mode.

If it is possible to run this ROM on my phone, would I need root? A custom recovery such as TWRP?

Thanks.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] sudo-user:
Yes, it is possible. Read the first post for how.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Asad_970:
Welp, it says "be on OOS 12 (C20 - C33)."

I am on C41.

Guess I'm just stuck 🥲
[OnePlus 8 / 8 Pro & 8T Cross Device Development] AnierinB:
Just flash global
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Asad_970:
I've been trying for over 24 hours to get the msm tool to recognize my device but it just wont. adb works fine as far as I know because my device connects to android studio, file transferring is working fine , my phone never shows up in the ports as the Qualcomm thingy it is supposed to pop up as.

When I try to boot into EDL, it just boots into fastboot or the stock recovery. :/

I really wanna get rid of OxygenOs, and it doesn't help that you're already teasing android 13 😅
[OnePlus 8 / 8 Pro & 8T Cross Device Development] AnierinB:
Join our telegram group (link in main thread) and kindly ask Jaba, he has the same device variant as you and is running LOS 19.1 based on oos12 sources.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] dh2311:
It used to work for me fine unrooted. Now even rooted with all the above I can't pass CTS Profile Match on YASNAC.

Edit: Solved, was following instructions that suggested changing build.prop but that created a mismatch as I couldn't set OP8 and amdroid 12

[OnePlus 8 / 8 Pro & 8T Cross Device Development] Flash1337:
Question : Does anybody else, notice that the screen/phone runs hotter on custom roms in games, compared to stock oos ?

Is stock being underclocked or something ?

Only asking, because everything runs smoother on evo x, but the temperature is noticeable on my device. And its with stock settings (not with any OC).
[OnePlus 8 / 8 Pro & 8T Cross Device Development] afrob101:
In fastboot mode, the phone scrolls from top to bottom by itself and I can't select anything. does anyone have a solution?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] afrob101:
Thx. I am now on KB2003_11_C.33.

oxygen updater now says my cell phone is the indian version. But that's not true. I bought a eu device.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] 5i1v3rStorm:
I bought a chinese version, pre-flashed with the global ROM but reflashed it to EU.

Of course I have no idea what version you have been on, if your OxygenUpdater was in advanced mode and what you flashed to your device but you can flash an Indian ROM on a device that was global once you bought it.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] BrickL0rd:

Step7: The adb runs till 47% and then "Total xfer: 1.00x" on CMD

This says the Phone (picture)

On Last step (reboot) the Phone says "Warning, No OS is installed"

I pressed yes. The Phone Booted. Fingerprint dosent Work now and everything Looks Like Stock OS12. What Happend?

can u help me @AnierinB ?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] BrickL0rd:
maybe, just maybe it is bc your flashed indian OOS. in oxygen updater you can choose which Device Version your download will be. its in the settings

i made an OTA update and now i am stuck on the boot loader is unlocked screen

i booted into fastboot mode and tried to boot to recovery but it booted into the the boot loader is unlocked screen ... after i flashed the recovery from post #2 i tried to fastboot boot recovery and had the same issue again ... rebooted to fastboot and tried to boot from there to boot the recovery and still no recovery bootable ...

did something changed in the last 2 months with the Rom or the recovery what i have missed ?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] 5i1v3rStorm:
Well... please read the last five pages. Your device is now softbricked, you will probably lose everything since your last backup and you will probably have to go to EDL mode, go back to stock, update to the latest OOS and restart your EvoX journey from there.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] afrob101:
I didn't find the recovery u mean. Do u have a Link? What phone do u have?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] lukaslinux:
i got the recovery workting again.... so i thought i download an older evo rom like 2 months ago and flash it via adb sideload. Bud i think my adb key files are on my other computer and i think they are needet if i want to keep my system and my data partition right? i tried to flash system via fastboot bud i got the post that the image header is not correct and i asume that system is only writable via sideload when the device is authorized right?

or does anybody know how i can get the authorization without booting into the system or atleased my data back?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] sbcrumb:

I was just changing wallpapers and noticed these weird blurry lines only near the notif area does anyone else get this. It only happens when the areas has like a solid color as shown in the scrn shot.

And here another example here is a wallpaper of a dune and i dont seem to see those lines. seems odd .

in this the lines have just seemingly disappeared.

Ok, got it. Thanks for the quick reply. I came back to this rom from derpfest. I like this rom better.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Bananosfank06:
I'm on the latest update, and I have it set up so a single tap lights up the AOD. But from there I can't go to the lockscreen with a double tap, only if the screen is fully off. Does the rom have a setting that I just missed, or is this intended?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] firoz3321:
Is there a way to backup and restore the Evolver settings ? Everytime i do a fresh install i am loosing all the setting. even after 2 hours of fiddling i couldnt restore a few settings :(

Can titanium backup do this ?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] bcluzel:
Hello,

I have a little problem.

I'm coming from OxygenOs EU C33.

When I try to do the adb sideload "rom.zip" the verification fail :

E: Current SPL: 2022-08-05 Target SPL: 2022-07-05 this is considered as downgrade

An then the install exit.

I believe the oos build is more recent than the EvoX one.

Is there any method to make it work ? Like authorising the downgrade?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] d3viou5:
I had the same problem downgrading from Evo 7 to 6.7.

Installing the rom through a fastboot installer fixed this for me.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] bcluzel:
Thx for the reply,

By "fastboot installer" you mean extracting all the partitions from the payload.bin and flashing the through fastboot ?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] d3viou5:
Correct. This is what I used. (unofficially of course).
[OnePlus 8 / 8 Pro & 8T Cross Device Development] kesavacherukuri:
What device are you using? Have you downloaded the latest recovery from the folder? AB has included the fix, that skips the error and installs the ROM as usual (also it worked for someone by using the latest LOS recovery, maybe try that ?)
[OnePlus 8 / 8 Pro & 8T Cross Device Development] bcluzel:
I'm using the oneplus 8t eu.

I downloaded everything as specified in the first post (2 days ago).

I will try the LOS recovery then.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] afrob101:
Have the same and no one can help me
[OnePlus 8 / 8 Pro & 8T Cross Device Development] bcluzel:
Well the fastboot installer method did not work for me, went fine during the whole process but no boot at the end...

The lineage recovery effectively permit to downgrade when side loading the rom but no boot either ...

I will stop there cauz I flashed again the oos 11 using the MSM tool and now the bootloader unlock slide in the parameter is greyed out ...

Thank for the help !
[OnePlus 8 / 8 Pro & 8T Cross Device Development] afrob101:

1. Battery Bar is off-center on my OP8Pro, it' swings off to the right edge, it's hard to tell the battery level as a result.

So has anyone else noticed that the brightness doesn't go up very high at all when playing HDR video? It's only like 50-60% brightness, even if you turn the slider up all the way. It only does this while watching HDR video. Also I just noticed when you stop watching something HDR and it goes back to normal, the dark colors that are black or closer to black seem very...greenish. I don't think they would show up in a screenshot considering it seems to be a display issue.

[OnePlus 8 / 8 Pro & 8T Cross Device Development] Imprezzion:
Weird. Still registers touch after holding finger on screen while unlocking from AOD. It's the only ROM still doing this..

Anyone else's camera not switching to the wide angle in the oos camera on the new build?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Agimax:
You have to turn off 'Ultra Wide Lens Correction' under settings, and everything will work as normal :)
[OnePlus 8 / 8 Pro & 8T Cross Device Development] hungmung:
Thank you sir.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Agimax:
You can hide the fingerprint on AOD in "settings>The Evolver>Lock screen>FOD on doze" it lets you hide the fingerprint icon, it but will still unlock in AOD. Its a feature... Otherwise you would have to double tap or wake-up to read fingerprint first. I like the instant unlock, wouldn't want it taken away :)
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Imprezzion:
That's not exactly the problem. If you use the FP and keep your finger on the screen after it unlocks it will register it as a "touch" thus opening the app under the fingerprint on the home screen for example. That's what annoys me as it will randomly open apps after unlocking if I don't let my finger go off the screen in time..

EDIT: found out it's kernel related. PE Plus worked fine without this "bug". Flashed Horizon kernel, it started to act the same. I flashed it back to Radioactive and after that it worked just fine again. What kernel is included in Evo X?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] drag0micr0:
I've had no problem using horizon or radioactive. EvoX uses the hasty kernel it looks like.

OnePlus 8T

I also went to Radioactive, because I have the feeling with Hasty to have much less battery life.

I hope there are still a few bug fixes, then this Rom would be really capable of everyday life.

OOS-Cam and Dolby already work great thanks for that :)

Currently it hangs on many small bugs.

1. always-on display consumes battery very strongly, probably because the pocket sensor permanently active display with the warning.

2. very often the pin code field and the fingerprint pattern on the home screen remain after returning from the AOD.

3. the brightness control would have to be adjusted a bit, since it is often much too bright and barely regulates.

4. still noticed today, when I listen to music with Spotify in the car via Bluetooth and the screen is locked the songs start to stutter and partly the music breaks off after changing the track. As soon as I unlock the screen it is back to normal.

Strange OnePlus 8 Pro photochromic camera lets you see through plastic

As you know, the smartphone OnePlus 8 Pro has a special camera with a resolution of 5 megapixels and a certain photochromic filter. It is not clear why OnePlus added it to its flagship product because it is able to take pictures using very special filters, which usually looks strange. However...
