Is it possible top get the old Launcher Back , or get the new Pixel Launcher working in this Rom. Batterie Life is great and better than Stock after a Clean Install of the newest Update, , i Love this Rom
[OnePlus 9 Pro] Terrorigel97:
Has this rom Oneplus featurs like Dolby Atmos etc?
[OnePlus 9 Pro] JohnTheFarm3r:
It doesn't.
[OnePlus 9 Pro] cws754:
I installed the latest update through OTA and it went pretty smooth. My only question is. Should I manually install the new boot.img or does that update with the OTA as well.
[OnePlus 9 Pro] JohnTheFarm3r:
You don't need to install boot.img if you already update through OTA. Boot.img is only if you're gonna flash the ROM through recovery.
[OnePlus 9 Pro] dariodamico:
This ROM became more ans more perfect with every update .
[OnePlus 9 Pro] BDProductions:
I get all the way to 'adb sideload df.zip' and it fails to read and install.

Using the same tools and folder I can install LineageOS 18.1 or crDroid without any problems at this, or any other stage.

That means the computer, drivers, and cable all work, and the phone is easily flashable with some other ROMs..

crd.zip was crDroid, and the dp.zip was the DerpFest zip renamed. See photo attached.

Anyone know how to solve this issue?

Thanks for any help anyone can provide.

Not new to flashing ROMs on phones, and most I have tried have flashed to the OnePlus 9 Pro without any issues in flashing.
[OnePlus 9 Pro] Samuel Holland:
Hi, sorry to hear, but are you using the boot image from the update post? A few posts before where the update is announced is a boot image. Go to Fastboot, flash this boot, boot to recovery, and flash the rom. I hope this might can help.
[OnePlus 9 Pro] GabrielSousa:
does this rom have the Ambient timeout ?
[OnePlus 9 Pro] vincemue:
just to be sure, that is not a clean flash as recommended for the version update.
[OnePlus 9 Pro] Sigray:
Is the FHD 60fps working with this rom / gcam?
[OnePlus 9 Pro] Zhono:
Definitely didn't do a factory reset on the phone, or there would be no point to any of this, since I'd have to reset and repair the watch anyway. Everything seems to be working fine with the dirty flash. If I had to wipe my data and reinstall/reconfigure all of my stuff, on top of factory resetting the watch, and setting all that back up, I just wouldn't bother updating at all.
[OnePlus 9 Pro] Hammerhand.17:
The ROM is awesome, just posting here to warning anyone who uses live wallpapers: they break boot, so don't install them until this is solved.
[OnePlus 9 Pro] problem_child:
Huh?

I'm using them though through pixelize kingsman magisk mod, everything works - root is there. Though I'm using it for the additional pixel features.
[OnePlus 9 Pro] TeaStay:
Yes, I got system ui crash with wallpaper engine.
[OnePlus 9 Pro] GolovaRaoul:
I'm stubborn and I still want to try this new update using OTA even while it's stated otherwise. I won't complain about bugs and only report them after I fresh installed if I encounter any.

If I try to do an OTA now, it says after "preparing first boot" "install error". Any suggestions what I can try to get the OTA to work?

Many thanks!
[OnePlus 9 Pro] GolovaRaoul:
Did you just flash the update using a custom recovery and that's it?
[OnePlus 9 Pro] alb94:
You using a custom kernel? If yes, you will not be able to update via OTA.
[OnePlus 9 Pro] Zhono:
Every step I took and everything I used, is two posts back. I flashed the new updated boot.img to both slots via fastboot, I used the custom recovery to sideload the latest update to both slots, rebooted once into android on each slot, then I used the custom recovery to sideload Magisk to both slots. No alternative tools or recoveries, if that's what you're asking.
[OnePlus 9 Pro] lukehong9:
Does the issue of the phone not ringing on outgoing calls exist for others as well?
[OnePlus 9 Pro] DonnerPlays:
Anyone else unable to update chrome or web view?

Because they are system apps I also can't uninstall them...

Edit:

Turns out deleting files of the play store fixed the issue

[OnePlus 9 Pro] Zhono:
I'm using live wallpapers perfectly fine. No crashes, glitches, boot issues, or anything else.

Yeah, I've had that issue since the first release of this rom. I don't make nearly enough phone calls to care, so I ignored it.
[OnePlus 9 Pro] BDProductions:
Yes, I install everything in the 1st post according to instructions for any ROM.

I wouldn't expect any other method to be reliable without someone reputable here posting alternate instructions.

Learned that was best way back on my HTC One M7.
[OnePlus 9 Pro] SK#Tech:
How is the battery life ?
[OnePlus 9 Pro] kdcw:
Undeniably the best rom I've used in oneplus9.

But I found some problems:

1.The warp change 65w seems to be abnormal | (the fastest speed is about 60w, but it only lasts for a few seconds, then it will continue 20w-30w).

2. The lock button of the multitasking UI application is gone, and the previous version can be used. The same problem also occurs on different models of mobile phones (one plus 8T、 redmi K30.....)

3. Under the full-screen gesture, in the gesture of swiping up to return to the desktop, the rounded corners of the application card are very strange, and a quick swipe will have a sense of separation.

(I'm just a Chinese high school student and my English is not good. Please correct me if I misspell words or use some incorrect grammar...)
[OnePlus 9 Pro] kdcw:
So fast I found a new bug.Seeing the picture i think you can get it.

[OnePlus 9 Pro] finkrer:
So, on OP9:

Fingerprint still doesn't work on Always On display

The clock still gets cut off by the camera safe zone

The interface still stutters without FKM tweaks (I've spent a day without them and the difference is night and day)

Would be really cool if those things were fixed.
[OnePlus 9 Pro] Hammerhand.17:
Could you try klwp? if it doesn't work, you can use adb uninstall org.kustom.wallpaper on an authorized pc to start again (which I'm sure will happen).

I've tried Kingsman's pixelify too and it works, but other live wallpapers doesn't; currently I use klwp and it crashes on every reboot if I am using it. Hope it can be solved; until then, I will disable the app on every reboot (hope I don't have any accidental reboot while so).
[OnePlus 9 Pro] Zhono:
I just installed kwlp(and the pro upgrade app, since I own it). Loaded up one of the default clock live wp's, works perfectly fine, no crashes or anything. Tried rebooting, and yup. First I got stuck on the owl logo. Forced it off and booted up again, get past the logo, but never fully reach the UI, and it crashes over and over, the screen turning off and on, etc. Unfortunately, adb has decided I am not authorized anymore, so I can't use adb to uninstall. Not sure how the hell to fix my phone now.
[OnePlus 9 Pro] vincemue:
I also have this, when VOLTE (4G) calls is activated in "Network & Internet --> SIN-Card"

When deactivated for me it does ring again.
[OnePlus 9 Pro] vincemue:

Does anyone know if there is a custom recovery I can boot temporarily that has a file manager/browser, so I can delete the god damned klwp so my phone will work again? Obviously twrp doesn't work. And I have tried every command, tutorial, etc to be able to do it from adb in recovery, I can't do it.

EDIT: Nevermind. Had no choice but to factory reset. Lost ALL of my data. So f*****g angry right now.
[OnePlus 9 Pro] BDProductions:
I expected the original post to be kept up-to-date on current ROMs...

I don't think I will continue messing with DerpFest, from all the unlock issues, flickering, and inconsistent locations for updated files required to install that don't match how most other ROM devs provide them (in the first post by updates)

Organization is important.

Sorry, but I don't see it here.

Hopefully, in the future, this ROM and instructions can all be lined up similar to how other devs manage their files and instructions. Seriously and respectfully considered. Good luck to everyone.

I kinda figured is was a problem of file versions and multiple install instructions and a lack of a single place where files and instructions are in sync.

Lineage and crDroid installed easy as pie, zero issues.

What's different about DerpFest installation? (actually rhetorical, for thought)

I will keep an eye out for posts that indicate this ROM has everything organized and working by a single instruction.

I hope DerpFest fixes the issues with FP/Face Unlock, screen flickering, and less important lockscreen charge time remaining...

The only thing that would make me install regardless of those 3 things is a working OOS camera that has working high resolution mode for 48 and 50MP images.

As a matter of fact, I do like to print clear photos on my laser printer, which is 1200DPI. An 8x10 photo on glossy would need 115.2MP to be fully photorealistic.

I know a lot of you don't care about anything but sharing on social media. That's fine.

The stock OOS camera takes very good high resolution photos in my experience, far better than the 64MP ones my Galaxy Note 20 takes in the same conditions. Sample of cheese curds I had with my burger for lunch just now, in not so great lighting.

Shot of the lobby taken on Note 20, because that's what I am on xda with today.

talk about washed out colors and blah photos...

I honestly believe cameras in phones have a lot more variability in output from phone to phone that would explain differences besides just user error from technologically challenged users. 🤪

My photos today were taken to share with a friend who works in food services industry, trying to get him to move to this town with better paying jobs and lower cost of living than where he lives now. Just an example of another reason someone might want to take larger photos.

Anyway, good luck to the devs for this ROM's continued improvement. I am sure you will get there eventually.
[OnePlus 9 Pro] benhidalgo:
I could never get DerpFest flashed, I never figured out what I was doing wrong. Even the help from reading how to flash it, I fail.
[OnePlus 9 Pro] Hammerhand.17:
Adb works fine for me, sorry. 😔😔 I couldn't find another way to solve it other than factory reset.
[OnePlus 9 Pro] Zhono:
So after I reinstalled everything, reconfigured everything, etc, etc, everything was working, including live wallpapers through Wallpaper Engine(as they were before), even after reboot. But, I jumped back to recovery and flashed Magisk, and everything went to sh*t again. Made sure adb worked beforehand this time, so I uninstalled Magisk, didn't help. Removed wallpaper engine, and everything just immediately worked again, didn't even need to reboot. So I guess we either get to have Magisk OR live wallpapers, but not both. How fun...
[OnePlus 9 Pro] Hammerhand.17:
I have used tasker to freeze live wallpaper engine on every reboot, just hope I don't have any accidental one, and @Ledrock can take a look into it for a future release, add it working fine on other ROMs.
[OnePlus 9 Pro] EtherealRemnant:
I installed this ROM on my 9 without any issue and I have solved most of the issues I had out of the box but for some reason, the stock launcher Google search bar is not functioning as a universal search which is literally the only thing I use it for. When I type in the name of an app, it just wants to search Google instead of giving me suggestions on my device. I added a search bar widget and it works fine. I have checked all the settings and can't see anything related to this behavior. Any ideas? I will have to replace the launcher if I can't get it to work because that's how I launch apps most of the time.
[OnePlus 9 Pro] DennisRawet:
I'm not sure if its derpfest fault or Google messages, but can't send or receive MMS..

I tried clear cache in app and disable automatic download of pictures

Edit: Fixed it! somehow my APN settings got borked.. added "default,supl,mms" (mms wasnt there before) in APN-type and it started working..

Deleteing and add new default didnt work, but the above worked :)
[OnePlus 9 Pro] AlexeXt:
The ROM is awesome!!!

Only one problem for me: fingerprint still doesn't work on Always On display.

Works only after double tap, power button or when the cable is connected.

The switch in the menu [DerpSpace --- Lockscreen --- Lockscreen UI --- Fingerprint wake and unlock (listen for fingerprint when screen is off) doesn`t work, maybe these things are connected.

OnePlus 9 Pro, clean flash according to instructions, Magisk.

Is there any solution?

Thanks

Hello all,

2nd day that i try to install the DerpFest Image.

going from OOS12 ( FAILED ), flashed stock via MSM ( i have LE2120, flashed a india recover pack ).

after that I flashed a recovery and DerpFest-12-Official-Shinju-lemonadep-20220416-1159.zip, but its failed to boot. stuck on boot logo.

after that i flashed a DerpFest-12-Official-Shion-lemonadep-20220318-0429.zip its boot successfully and boots, after i flashed a latest image, and its successfully boots.
[OnePlus 9 Pro] GabrielSousa:

[OnePlus 9 Pro] Zhono:
So unfortunately, if you, like me, had constant phone crashes on this rom until the March update which completely eliminated the crashes... I don't recommend the new April update. After having to do the factory reset over that fact that simply having a live wallpaper essentially soft bricks your phone, I'm back to having constant crashes on the latest update. Left early in the morning for the day, and not 20 minutes later, hard crash. Forced it off and rebooted. A few minutes later, another hard crash. Only this time, after forcing it off, it wouldn't boot. At all. And so I was left for the next 9 hours with no phone. Couldn't contact anyone, couldn't get a ride home so I had to walk almost an hour and a half after already doing a solid 8 hours of various work and walking, couldn't listen to music, which I would normally be doing for that entire length of time. Finally got home, had to use recovery and factory reset AGAIN after reflashing the rom again. Seriously, this sucks.

I highly advise people to either stay on the March update if you aren't having any issues on it, or if you haven't switched to this rom yet, just stay on stock or look into other roms. I like the customizations on this rom, but the number of additional things that just get further broken with every update just isn't worth the ordeal. Hopefully things will get better for those you you who stick it out. Thanks to the devs, either way. Even with all of the issues, it was STILL somehow a better experience than stock. But it's just been too many times now that I have been out and gotten stranded without a working device.
[OnePlus 9 Pro] vincemue:
I do not know, what is the issue on your side, but want to mention, that on my side the update just works fine without any crash.
[OnePlus 9 Pro] Zhono:
Don't know. It was an issue for me on the original release and on the February update. Fully wiped my phone and went back to stock 11, then reflashed to Derp. Same issues. I decided to just live with the crashes, because I REALLY don't want to run stock, but when the March update came out, I flashed, and never had a single crash again on that update. Sure, having absurdly slow charging sucks, but no crashes. But now on the latest update, here I am am again with endless crashing, for no well explained reason. And it's not like I'm doing anything unusual, or running a bunch of iffy root stuff.
[OnePlus 9 Pro] vincemue:
sad to hear. hope you find a good solution
[OnePlus 9 Pro] kolyan_2099:
I downgraded to 11, but its still cant flash latest Derpfest directly, its flashed only via flashing first the previous build from 3.2022, after that i flashed a 4.22 and its boot successfully. I didn't sure why it that, this is first custom rom that i installed on my LE2120, i come from Mate 20 pro, 4 years of full stock :), before that i had many phone with many custom roms.

also I have problem, the phone doesn't wakeup when double tap, the option is enabled in options ( system > gestures ) but doesn't works.
[OnePlus 9 Pro] DonnerPlays:
Double tap wakeup doesn't work for me either.

If you disable the "prevent accidental wakeup" feature right below that option it does work.

I'm guessing the "prevent accidental wakeup" is a bit to preventing
[OnePlus 9 Pro] kolyan_2099:
Thank you. I disable a "prevent accidental wakeup" and double tap works now. Thank you a lot for a tip.
[OnePlus 9 Pro] abadasstanker69:
I've been using this as my DD since the Derp updater started telling me there was an update. I think it's been a little over a day or 2. I didn't clean flash. I just took the update and then installed magisk to inactive and rebooted.

The only 2 things I've noticed so far that's a little different is that usually I kept my phone on 60hz for battery life and.... It's a phone. Who cares? But on the update, 60hz was super janky. It ripped on transitions and felt super laggy. Switched it to 120 and everything was perfect. So I flipped the switch for variable refresh and now I feel like my battery life is back to normal.

The second thing is the phone not ringing when I'm calling out. Sometimes you can hear the start of a ring, then it goes quiet until the other end picks up the phone. It makes you think you either disconnected or hung up.

Other than that, no issues. Great update guys. Good job.

I haven't had any crashes, just weird issues like apps acting like it's the first time I open them (having to set up Speedtest app every time, a game I play always makes me log in, etc), Chat features aren't registering in Messages and I have never had a problem before, GPS doesn't always work, and the Google search bar on the home screen doesn't search my apps (my most frustrating issue as I use that functionality a lot). There are definitely some weird issues with this ROM though that I have never seen before but fortunately, no crashes. 34 hours of standby time with 7 hours screen on time on a single charge with 21% left has me blown away too, especially since I only charged it to 88%.
