[OnePlus 9 Pro] Tommohawkuk:
@Ledrock awesome ROM thank you for all the hard work. Works pretty well on my UK oneplus 9 pro. Haven't seen any significant issues. Couple of app crashes here and there but nothing specific. OTA update worked flawlessly today.
[OnePlus 9 Pro] stez827:
does this give you all the pixel benefits like unlimited photo and video backups
[OnePlus 9 Pro] Tommohawkuk:
There is an option in settings to make your device identify as a Pixel phone which then enables unlimited storage yes.
[OnePlus 9 Pro] stez827:
Awesome will be flashing later then
[OnePlus 9 Pro] GolovaRaoul:
I found the previous build pretty good so far. I will flash the update and report any feedback back. Can I just update OTA, even if I rooted?
[OnePlus 9 Pro] chefcesarpr:
You will lose root, but yes. and it's super easy to get root back.
[OnePlus 9 Pro] vincemue:
just install magisk on inactive slot before restart, but after the OTA install
[OnePlus 9 Pro] Zhono:
While technically the USB connection is detected on Windows again after the latest update, the actual connection is HIGHLY unstable. Trying to copy my music collection over, and I can get like 50MB and the connection drops and I have to unplug it and reconnect it and start over, then it dops again after copying practically nothing. Oddly enough, I tried tossing just my Modest Mouse collection into a 7zip file. The 5GB file copied over in less than 10 seconds without issues, and I just extracted it in Solid Explorer. But that's going to be a real nightmare to do for 150GB of music, considering space constraints, and the fact that just that 5GB file alone took about 45 minutes to extract.

Also, a PSA for anyone with a Samsung watch: doing the OTA update will break your watch connection, and you'll need to factory reset the watch to pair it to the phone again. I thought I learned with the previous update. I had updated manually via recovery, and my watch was still paired just fine. The OTA kept bugging me about updating(even though I was already updated), so I just gave up and let it reinstall the update, and my watch was no longer paired. So with this update I thought I was being smart by backing up the bluetooth stuff in the partition backup app while it was working, and then restoring that(working B to not working A) after the update. Didn't work. In fact, I probably made it worse, since I also had to pair my headphones all over again this time as well which I didn't have to do before. Maybe those partitions don't work the way I assumed they do. If anyone knows how to NOT have to factory reset my watch after every single rom update, let me know.

*edit* And before anyone says it, yes, I know that this is more a problem with the way Samsung pairs the watch with the phone and requires the factory reset, and not technically a problem with the rom. But it's still something people are going to want to be aware of, if they have a Galaxy watch and are planning to keep up with the rom updates.
[OnePlus 9 Pro] frost_icewind:
The last update seems to have messed up rapid charging... It still charges rapidly for a few seconds, then drops down to regular charging
[OnePlus 9 Pro] cellphones177 khanhhoi:
i have a problem, any help pls
[OnePlus 9 Pro] acloh0411:
put your zip file into same adb /fastboot folder.
[OnePlus 9 Pro] stez827:
Make sure you only have one device connected
[OnePlus 9 Pro] chefcesarpr:
Don't know what your issue with usb can be. I just try and transfer 1gb of music files with no problem. Usb 3 on pc with a OP cable.
[OnePlus 9 Pro] cave.man1908:
I had the same problem transferring files from PC to OP. I ended up pushing/pulling files via adb.
[OnePlus 9 Pro] applyscience:
I am having issues with bluetooth audio with the Bud Zs that came with my OnePlus 9 order (non pro) It has worked flawlessly on every rom ive used, including this one. It broke after the the latest OTA update.

This is my 2nd OTA from Derp. (so, 3rd iteration) and my initial install as well as the first update all played bluetooth audio perfectly.

now it cuts out every 5 seconds.

ive attempted various audio mods, bluetooth setting tweaks and have no real clue whats changed to have caused this.

Its very well this isnt a DERP problem specifically. Correlation =/= causation but wanted to ask, here regardless.

everything else , especially with the pixel services, are working perfect as usual.
[OnePlus 9 Pro] Salilsarkar:
when the rom was first released I heard that developers are working on oos cam ,, is it added yet??
[OnePlus 9 Pro] alb94:
Not yet.
[OnePlus 9 Pro] teflon252:
Having issue with OTG UsB Flash..they're not being seen both before and after update
[OnePlus 9 Pro] SheryarHassanKhan:
So guys i tried this rom, and im loving it ♥️.

I tried StagOs but i find this one way smoother than it on my 9 pro.

There are however some occasional hiccups, and some apps are very choppy like spotify, Twitter, and google play.

Kindly increase the fluidity of this rom, it is the best rom I've ever used since the early cyanogen mod days on my s5 ♥️♥️

Im using gcam and the results are very good.

Battery life is also very good, same as oos11.
[OnePlus 9 Pro] SheryarHassanKhan:
How long do we have to wait? Any idea?
[OnePlus 9 Pro] SheryarHassanKhan:
Hey dev! Can you increase the smoothness of the rom?

- There is a small stutter while going to the home screen

- Some apps are very choppy
[OnePlus 9 Pro] teflon252:
U don't have any OTG issues...when connecting UsB storage?
[OnePlus 9 Pro] alb94:
Unfortunately there is no forecast.
[OnePlus 9 Pro] saminaminahehe:
lots of stutters on the latest build, I'll stick for the feb update for now.
[OnePlus 9 Pro] darkness4every1:
Since Nameless was discontinued I'm thinking about switching to Derpfest, but last time I tried the rom it was very laggy, full of stuttering, felt extremely slow and was full of bugs.

What's the current state of the rom?
[OnePlus 9 Pro] stez827:
If you don't care about customization and just want complete stability try stagos it's pretty stable
[OnePlus 9 Pro] GolovaRaoul:
You can 'fix' those with FKM
[OnePlus 9 Pro] Dharani_V:
How ? I have FKM Installed.
[OnePlus 9 Pro] saminaminahehe:
did you have the same issue too and fixed it with FKM?
[OnePlus 9 Pro] Dharani_V:
Thank you. Applied it. let's see if it helps
[OnePlus 9 Pro] saminaminahehe:
how is it?
[OnePlus 9 Pro] GolovaRaoul:
For me it fixed the problem completely. You can play around with the settings. I personally disabled the prime cluster since I can enjoy my phone stutter free with 'only' the big/little cores.
[OnePlus 9 Pro] bmaggot:
As it was said, charging is pretty slow in this version. How can we fix it?
[OnePlus 9 Pro] StraightVino:
wow, thanks a lot for that info. the stuttering is gone now. everything runs super smooth. 👌👍
[OnePlus 9 Pro] Dharani_V:
Stuttering is gone now . thanks @FJB_LetsGoBrandan_FJB .
[OnePlus 9 Pro] Dharani_V:
Same issue. Previous build was fine. Charging speed is very low in this build
[OnePlus 9 Pro] saminaminahehe:
Fixed the issue with stutters thanks to @FJB_LetsGoBrandan_FJB. Now, the only problem is the charging speed. Seems like its not stable, like a hit or miss.
[OnePlus 9 Pro] vincemue:
how do you charge, what equipment, how do you check if its correct speed?

what do you expect, what do you actually see?
[OnePlus 9 Pro] saminaminahehe:
I always charge at 10-15% battery using the charger that came from the box. Usually, it charges for about 20-30 mins. But the latest update from this rom charges my device for an hour or more.
[OnePlus 9 Pro] Zhono:
Same. Original fast charger and cable could charge the phone from 15% to 90% in like 20-25 minutes. My wireless charger could that in about 40 minutes. Now, the original charger/cable only gets me about 4% in that 20 minutes, and the wireless charger I don't even know, since I'm not going to wait long enough to find out. Several hours at least, it seems. I don't let my phone live on the charger, like most people I know, since I want to have a battery last for more than a year. I charge once per day on my wireless charger for about 45 minutes to an hour, or up to 90%, and that's all the charging it gets until the next day. I almost never actually use the charging brick and cable for fast charging, but on the rare occasion that my battery is almost dead and I need to leave the house right away, I REALLY need the fast charger to be able to do its business and get me power in a hurry. Hopefully fast charging will be restored in the next update.
[OnePlus 9 Pro] icemantogy:
friends oos camera and dolby added?
[OnePlus 9 Pro] Dharani_V:
Facing the same issue. It was working fine but all of a sudden its not working after the update
[OnePlus 9 Pro] darkness4every1:
Did you disable "Use Pixel battery stats provider" from settings>battery?
[OnePlus 9 Pro] saminaminahehe:
After going back to OOS for almost a week, I decided to try and flash again the latest derpfest (march update). Now, everything works fine. The charging speed was the same as the last update and stutters are gone.
[OnePlus 9 Pro] Semetery:
Remove.
[OnePlus 9 Pro] Semetery:
Seemed to do the trick for me
[OnePlus 9 Pro] DennisRawet:
Hey!

Installed Derpfest today on my OP9Pro since i hated the ColorOS so much...

My first impressions are really good!

I had a small hiccup in the beginning with my sim didnt want to "load", after an reboot it worked perfectly.

Had som minor stutters in apps like Instagram and Gmail, with @FJB_LetsGoBrandan_FJB fix (https://xdaforums.com/t/rom-12-0-18...cial-lemonade-lemonadep.4395911/post-86376201) it seem to disappear.

Cant say anything about batterytime yet, but well see!

The only negative is that you cant use 100% of your camera.

looking forward to camera port!

Really recommend this rom if youre looking for an replacement from the **** OP released.
[OnePlus 9 Pro] Arcide:
Wait is someone doing the port?? That would be amazing
[OnePlus 9 Pro] ravichaudhary133:
@pranavasri is into it. He is stuck for sometime. A team of devs if unite will do wonders in no time.
[OnePlus 9 Pro] problem_child:
hey all

I assume the wifi and LTE issues are known? I mean the performance compared to stock is worse (LTE) or just bad (WIFI 5gfz)?

What's the main reason for that? Do we just need proper drivers in the rom or?

as for batter life - I'm getting around 3h SOT.

Outside of this - loving the ROM, as far as I see it's best replacement for Oxygen 12. We can just call oneplus a hw vendor nowadays
[OnePlus 9 Pro] Samuel Holland:
Wow, really nice job maintaining lemonadep. Thank you for sharing and keeping up with this.
[OnePlus 9 Pro] Android33:
I still can't connect to my PC since getting this ROM even after the updates and it charges extremely slow I've tried different cords and PCs to no avail please help I was enjoying the ROM until these critical issues came
[OnePlus 9 Pro] Samuel Holland:
I hope you figure this out, when I first got this phone I tried multiple cables and the only one that worked(since at the time I didn't have any type c ports on PC) was my cable from 8 pro. On the other hand my 8 pro wasn't as picky.
[OnePlus 9 Pro] darkness4every1:
Did you do a fresh install from latest OOS 11? Are your drivers ok?
[OnePlus 9 Pro] Android33:
Yes I did a fresh install from os 11 then updated via settings then the problem began to happen and has persisted since and since I can't connect to pc I can't msm tool it back that's my biggest problem and the fact it charges slow
[OnePlus 9 Pro] problem_child:
on this note, I tried to troubleshoot the wakelocks via bbs and battery guru. I've noticed a ton of wakelocks from what appear to be some google services.

Is there a way to disable/block wakelocks on this ROM / kernel combination? EX Kernel Manager and FKM dont' seem to offer the option... Does it need some terminal magic? And if so what is it? :D

thanks for the help!
[OnePlus 9 Pro] .DeluXer:
Have a look at Settings-->Battery
[OnePlus 9 Pro] GolovaRaoul:
I wan to say that I have been daily driving this ROM for around a month now and I'm very satisified with it. I enjoy the customization and the stability of this ROM. Overall I can say that my battery life is pretty nice, I can get around 5 hours of SOT.

The issues that I currently still experience are:

- Fast wireless charging is not working. But now I can leave my phone on my wireless charger without having to fear that it keeps topping off at 100% which is actually kinda nice

- I have a wallpaper that changes based on Day/Night, but for instance the settings/gmail app don't update on this unless I close/re-open the app (not re-launching but actually closing it). That might also just be an android 12 thing and not really related to this ROM. Apps like Tasker do automatically update well.

- I know it has been said 100 times before but it would be cool if the Oxygen OS cam was ported but I guess that's not as easy as it sounds.

Issues which I had in the previous build (wifi/nfc) are fixed with an OTA update which worked flawlessly. Looking forward to future builds! Thank you very much for your effort :)
[OnePlus 9 Pro] evasarolta:
Nice ROM , but almost outdated for this device compared to others
[OnePlus 9 Pro] Kingslanding:
Is the lastest google recorder working on Derp 12?
[OnePlus 9 Pro] problem_child:
Yessir, pixelify by kingsman magisk mod
[OnePlus 9 Pro] Kingslanding:
Many thanks! Would Derp 12 for oneplus 9 keep updating in the future?
[OnePlus 9 Pro] problem_child:
I believe yes because that magisk mode adds Google pixel props (i think) and therefore google play ships you the version that has it. So far so good and I've had updates of the phone app
[OnePlus 9 Pro] Kingslanding:
Got it. Thanks a lot
[OnePlus 9 Pro] ezpz.MiDAS:
Does face unlock work? And if you wan't Magisk, do you sideload the apk.? Can't seem to find zip/img on the repo anymore. Thanks!
[OnePlus 9 Pro] finkrer:
Yes and yes. The magisk .apk actually works as a zip if you rename it to .zip.
[OnePlus 9 Pro] RidiCrow:
Hi, great to see the new update.

Though desperate to install, I'd like to know if USB audio works?

Hopefully someone who has installed it will tell me if it works!

This is important to me. Thank bro!!
[OnePlus 9 Pro] problem_child:
how should I test it? I used usb-c to 3.5 mm audio and listened to music on the OP9pro with this rom and arter97 kernel. all seems to be working fine.

I did notice that if I was in silent mode (with the slider on top) that the music was muted. I solved it by manually kicking the mute-off for media. This seems like a small bug :)

Also, on the arter97 kernel - had to try it as it seems this was legendary on the OP7. Must say I'm impressed by now: feels even snapier then before. hope to see better SOT time also.

Will post an update after some days of use.

Also also, I tried the crDroid (I'm so furious about OS12 that I had to try everything) and must say Derpfest just feels smoother, cleaner and more refined in general. I didn't notice any crucial differences in features but the fact that pixel apps and google apps are already baked in just make it feel easier smoother and overall better imho. Though crDroid is faster in updates but 1m cadence is enough - better then OnePlus anyway :D
[OnePlus 9 Pro] Android33:
Yes to both it was doing fine at first then randomly started to have these problems been trying to just wait for updates (cause that's all I can do considering I can't connect to my PC in any form not adb not regular not even in msm) really need help so I can at least change the ROM
[OnePlus 9 Pro] cws754:
Have you tried to clean out the port on your phone? I had a similar issue. My phone would charge but not connect to my PC. I took a sewing needle and scraped my port clean and problem solved.
[OnePlus 9 Pro] Android33:
I'll try that appreciate it 👍🏾
[OnePlus 9 Pro] darkness4every1:
Try to manually install google drivers after you've normally installed them.

Device Manage (Action> Add legacy> second option and look for android/google bootloader or adb, also install OnePlus drivers if you haven't.
[OnePlus 9 Pro] GolovaRaoul:
Works for me!
[OnePlus 9 Pro] samwhiteUK:
Stock has an option to allow you to choose whether the media volume gets muted with silent mode or not. Maybe this ROM does too
[OnePlus 9 Pro] RidiCrow:
yep, it works.

I installed derpfest and I'm so happy for it.

I've had enough of colorOS or OxygenOS(11.2.10.10,12.1,all of then).
[OnePlus 9 Pro] germarican:
Is there an implementation of the oos camera in near future like on nameless rom
[OnePlus 9 Pro] DarkShadow69:
Can anyone please confirm if banking apps work on this rom?

Thanks in advance
[OnePlus 9 Pro] glover279:
Cant seem to setup the Samsung Pay watch plugin. "Unauthorised changes were made to your phone". This works on other roms
[OnePlus 9 Pro] keshav26:
Yep it does but be careful to autorize the app if you have a rooted phone
[OnePlus 9 Pro] darkness4every1:
Nameless was discontinued for 9 Pro
[OnePlus 9 Pro] Atul Menon:
https://github.com/OnePlusOSS/android_kernel_oneplus_sm8350/tree/oneplus/SM8350_S_12.0_9Pro A12 kernel sources are out
[OnePlus 9 Pro] vincemue:
for me it works with magisk and zygisk
[OnePlus 9 Pro] germarican:
I know that's why I'm asking if the developer here could maybe implement it as well if it's possible for this device, the have it on the 8 and 9r working
[OnePlus 9 Pro] Presterin:
How do I completely disable Ambient display? I seem to have everything turned off, but still when I double tap screen it shows Ambient display.
[OnePlus 9 Pro] Zhono:
Settings/DerpSpace/Lockscreen tab has Ambient display settings if you haven't already found those. Under both the Ambient Display menu, and the Lockscreen UI menu.
[OnePlus 9 Pro] Presterin:
I think I have disabled all. Screenshots are partly in finnish but you get the idea. Double tap on off screen still shows ambient display and sometimes it wakes up when I pick up the phone. I want to wake lock screen with double tap and get rid of ambient display and aod.
[OnePlus 9 Pro] stryver:
My screen is stuck on 60hz all of a sudden. I have run derp since first release and always update. Any suggestions before I reinstall the ROM?

EDIT: I figured it out, somehow my battery saver was on. FML. Sorry guys...
[OnePlus 9 Pro] vincemue:
try the setting in the display section --> tap to wake. (close to the bottom)

when I disable that one, my phone does not wake with double tap.

but it still woke up after pickup

[OnePlus 9 Pro] Op9ProMroFro:
Hello Dev I have status 1 in recovery and says it's for 9 pro Lemonadep and

I have the 9pro LE2123 I used the boot.img file from Lemonadep

It's a recovery issue when yes can I use the latest lineage recovery?
[OnePlus 9 Pro] Aman dolani:
Even I am facing similar issue where the adb sideload fails with error : Package is for product lemonadep,OnePlus9Pro but expected lemonadep.

I am using derpfest boot.img and I have 9pro LE2121 (India).

Please let us know how can we flash the latest rom?
[OnePlus 9 Pro] Ledrock:
Please find the updated post. I apologise for now providing the same before.
[OnePlus 9 Pro] Aman dolani:
Thanks! The new boot.img worked. Excited to run this 12.1 beast finally!!!
[OnePlus 9 Pro] thznutz87:
Derp updater keeps failing? Anyone else successfully update from within the ROM?
[OnePlus 9 Pro] Ledrock:
Tried sideloading? Since it's a version upgrade it may require a clean flash.
[OnePlus 9 Pro] Presterin:
Everything was fixed after installing todays update. Haven't touched the toggles and it just works.
[OnePlus 9 Pro] Presterin:
Just installed OTA, dirty from update app. Seems to be fine so far, update took a really long time though.
[OnePlus 9 Pro] vincemue:
thanks again!

with "clean flash" you mean factory reset?
[OnePlus 9 Pro] JohnTheFarm3r:
Factory reset in recovery / Formatting data.
[OnePlus 9 Pro] vincemue:
alright.

is there a current way to easily get the apps and data back afterwards or is it required to redownload and setup everything from the beginning?

I used titanium backup some years ago, but this does not seem to be a thing anymore.
[OnePlus 9 Pro] JohnTheFarm3r:
Swift Backup is one alternative of course. You would need to initial set up your phone, but you can restore the majority of your apps with it.
[OnePlus 9 Pro] dariodamico:
Exelent ROM . I have notices a bug in setting/oneplus setting/DC-dimming desabled After reboot. Thanks u for this ROM .jeep doing good job.
[OnePlus 9 Pro] gillim74:
Is there gonna be a dotqs with blur for this one like the 7pro?
[OnePlus 9 Pro] Salilsarkar:
i was perviously using aospa beta 1 for my 9pro, so i tried to flash the boot img provided in this thread but when i flashed it and tried to boot into the recovery mode its stuck nothig happens and the phone is bootlooped.
[OnePlus 9 Pro] Unifire:
i flashed the boot image boot(Lemonadep).img from OP on the lastest oos and now device doesnt show and recovery doesnt boot
[OnePlus 9 Pro] gillim74:
Navbar pill dont dissapear.never mind i got it working!
[OnePlus 9 Pro] unloseking2500:
Charging is still very slow with this update. No wrap charging.

Is anyone else having the same issue?
[OnePlus 9 Pro] vincemue:
As it is a new Version, I also need to sideload the linked boot.img before,right?

So basically same installation steps as like coming from OOS11.
[OnePlus 9 Pro] vipinpvarghese:
Which camera app is used in this ROM?
[OnePlus 9 Pro] zefyx:
The new 12L build of DerpFest is undoubtedly the best custom ROM for the OnePlus 9 Pro today.
[OnePlus 9 Pro] novo2o:
Same here after OTA update from previous version
[OnePlus 9 Pro] novo2o:
Edit : fast charge kicked in after a minute or so, and maxed at 20 watt or so, but no warp charge.
[OnePlus 9 Pro] novo2o:
Shout-out to the devs for this ROM. You guys rock. So many features and custom. options.

The ROM is really top notch.
[OnePlus 9 Pro] acloh0411:
why i getting bootloop from recovery after flash new boot.img?

how i get boot to system again?
