Is it OK to flash on OOS 12?

Does this rom include OOSCAM?
[OnePlus 9 Pro] stez827:
Dude this rom hasn't been updated in a while and no longer is supported and oos can has just been ported today the only rom with it currently is Nameless you can't expect developers to add it in less than a day
[OnePlus 9 Pro] chenxuwen:
Thanks for letting me know.

OOSCAM is a big problem for custom rom now. Oneplus 7 pro just got it recently. But 8T got it much earlier.

what is the difference between lemonade shinju and shion?
[OnePlus 9 Pro] gokou46:
will this rom work on c.63
[OnePlus 9 Pro] nani16:
Don't know...but they(derpfest devs) specifically mention that you need to be on OxygenOS 11.2.10.10 version
[OnePlus 9 Pro] gokou46:
Where do i check for oxygen 11.2.10.10 cant seem to find it. All i get is build number LE2125_11_C.63
[OnePlus 9 Pro] Samuel Holland:
I believe there is a msm tool that will set you back to or before this version.
[OnePlus 9 Pro] jahanzaiblohani:
Is dual sim working on your phone ?
[OnePlus 9 Pro] TheKnux:
They're device codenames.
[OnePlus 9 Pro] Terrorigel97:
Why this rom get no new updates? :/
[OnePlus 9 Pro] TheKnux:
Cause it was EOL like 2 builds after release. 😂

Do other people have wifi issues with this ROM? I have to restart multiple times to get the WiFi to work sometimes.
[OnePlus 9 Pro] AlexeXt:
No problems with WiFi for me (used 4 month)
[OnePlus 9 Pro] Samuel Holland:
At first way back when, I had a few issues, but haven't had any for months, although I am running Arter kernel.
[OnePlus 9 Pro] gokou46:
Hello quick question i Updated to anroid 12.1 sept 7. Will this rom work on my Phone.
[OnePlus 9 Pro] Samuel Holland:
As far as I am aware, you need to be on latest oxygen os 11 to flash without issue.
[OnePlus 9 Pro] gokou46:
I was thinking of the same thing but i also see that its for anroid 12
[OnePlus 9 Pro] Samuel Holland:
Yes it's Android 12 based off of oxygen os 11.👍
[OnePlus 9 Pro] gokou46:
So would i be good to install or do i need to downgrade for the rom to work.

Sorry im kind of new to this.
[OnePlus 9 Pro] Samuel Holland:
Downgrade, I guess it couldn't hurt to try it while on oxygen os 12 if your gonna MSM back to oxygen 11. I would just make sure to have MSM tool set up and have the drivers installed, etc, for recognizing your device for adb, fastboot, and EDL, before attempting. That way if it doesn't boot, you can just MSM back, update to latest Oxygen 11 for both slots, and then it will work for sure.
[OnePlus 9 Pro] spamerobaldomero:
hello!! would like to know if there is a pristine build anywhere to download, because I particularly hate gapps and dont need that trash on my phone.

thanks in advance
[OnePlus 9 Pro] sev7en:
Great job!
[OnePlus 9 Pro] avid_droid:
Guess who's back with another 9 pro?

I wish this Rom was still being developed and updated! Hands down one of my favorites.
[OnePlus 9 Pro] solar666:
There is an unofficial version updated recently, check here:

https://sourceforge.net/projects/derpfest-13/files/lemonadep/DerpFest-13-Release-Tango-lemonadep-20231021-1328.zip/download

It is only for the 9 Pro version
[OnePlus 9 Pro] BobaHeisenberg:
I'm definitely going to check it out, thank you for this. Much appreciated
[OnePlus 9 Pro] DarkShadow69:
Hi,

Do share your experience here as well.

Thanks in advance.
[OnePlus 9 Pro] kodayoda713:
On it currently and really enjoying it. Have the eva kernel flashed and a few FKM tweaks. Almost perfect, just a few UI lags, but otherwise great customization and feel.
[OnePlus 9 Pro] hammered58:
running this now coming from 13.1.0.591,, no complaints,
[OnePlus 9 Pro] Mikoros:
Hey,

First thanks for the ROM. I'd like to test it but I have a few questions : does this ROM support R/W for all partitions or does it still in RO ? Does is support OP Cam and Warp charging ?

Thank you in advance :)
[OnePlus 9 Pro] cri777:
"package is for product lemonade,oneplus 9 but expected lemonade"

i checked twice,the boot image is for lemonade, the rom is also for lemonade, any fix?

edit: nvm i tried with derpfest shion and its working

with the shinju one didnt work, i'll leave the comment in case someone has the same error
[OnePlus 9 Pro] applyscience:
Last Updated 2022-03-18

Almost 2 years since an update, so I'll assume you were on a higher firmware than this rom is Ware of.

I am currently on evolution A12 and curious. Do I HAVE to downgrade to oos or is it just recommended. Thanks
[OnePlus 9 Pro] infamousvincci:
More stable than my finances. Daily driver worth it.
[OnePlus 9 Pro] mattie_49:
Yes you have to unlock bl.

Oos 12 yes msm back to A11. Local upgrade won't downgrade. Take at least one Ota or use copy partitions zip.

To flash critical partitions bl must be unlocked. I'm on build using Magisk 24.1 ,unlocked bl & rooted achieving widevine L1, passing safety net. !!
[OnePlus 9 Pro] IamTheBRAVE:
Good to know 👍
[OnePlus 9 Pro] Dharani_V:
Sideloaded after installing rom . First flash the boot image given in the instructions , reboot to recovery flash rom then flash magisk.
[OnePlus 9 Pro] sefai77:
what you mean : Individual sim toggle (for some dualsim devices)

this is like smart dual sim ? for example like receiving a call from the second sim card while calling with the first sim card?

Wanting to start a clean slate Derpfest 12.0 with my OnePlus 9 Pro. Is it ok to wipe internal then flash Derpfest 12.0?
[OnePlus 9 Pro] break.cold:
Factory wipe through LOS recovery. Factory wipe before is necessary and after (highly recommend) installing rom
[OnePlus 9 Pro] zXDexusXz:
When I follow the instructions, I get this error on sideload:

serving: 'DerpFest-12-Official-Shion-river-20211220.zip' (~47%) adb: failed to read command: No error
[OnePlus 9 Pro] break.cold:
Bro, do some searching few pages back already mentioned this problem occurred to one user.

Anyway, use latest Platform-tool. Check this post it might help you.

https://xdaforums.com/t/rom-12-0-st...cial-lemonade-lemonadep.4395911/post-86347177
[OnePlus 9 Pro] zXDexusXz:
Yeah I have done exactly this... And whenever it stops at 47%, the phone will reboot to: QUALCOM CrashBump Mode
[OnePlus 9 Pro] break.cold:
Are you coming from A11 OOS or any other custom rom or A12 ColorOS?
[OnePlus 9 Pro] zXDexusXz:
Came from A12. BUT I have done the MSM downgrade to A11, and updated it to latest A11.
[OnePlus 9 Pro] break.cold:
Try again. Follow the steps again. Use LOS recovery and do factory wipe.

Or try changing slots and then reboot.
[OnePlus 9 Pro] zXDexusXz:
Still error. Tried LOS recovery. Some progress there, but it will only boot into fastboot.
[OnePlus 9 Pro] break.cold:
Try changing your slot A or B.
[OnePlus 9 Pro] zXDexusXz:
Never done this before. I come from Nexus generation and 1st gen Pixel of rooting, so I'm kinda rusty.

Also I tried to boot on stock recovery just for fun. It ****ing booted on stock OS.
[OnePlus 9 Pro] break.cold:
Go to fastboot and do the following:

1. fastboot flash boot filename.img (either use front page recovery provided or use LOS recovery, your choice).

2. Rebbot into recovery and do factory wipe.

3. Install rom through adb update by doing following: adb sideload filename.zip and press enter. Make sure the rom is installed completely meaning it will give verification warning sign and press YES and it will install update 1/2 2/2. If it doesn't show install update 1/2 2/2 you doing something wrong and start from fresh.

4. Don't install Gapps since it's already included.

5. Highly recommended do factory wipe again and then reboot.

6. Once you booted into system and you setup completely and again go to recovery adb sideload Magisk zip (if you want root).

That's it.

I understand, it was a lot easier back than. When Nexus 4 and 5 and 6 excited. It so simple to root, flash custom roms and custom kernels. It wasn't that much frustrating as of right now. It's a headache, trust me
[OnePlus 9 Pro] zXDexusXz:
Still the same problem... Not sure if I'm missing something. I would need to go to stock OS atm, just so I can wake up in 6 hours, and go to work. Is it possible that you can add me on Discord if you have? Maybe it's easier to show you exactly how I do this. If you have it, add: Zentrox#0001
[OnePlus 9 Pro] frost_icewind:
How'd you guys keep Widevine L1?

I got bumped down to L3
[OnePlus 9 Pro] Dharani_V:
use msm to go to oos then do one ota update and get to the latest oos 11 version. then follow flashing instructions you should have L1
[OnePlus 9 Pro] applyscience:
I have a few responses after daily driving for a few days.

Gesture controls don't work in settings. Everywhere else works great. Gone over deep and general system gesture settings and couldn't see a solution. Hopefully I'm just missing something obvious.

Edit: changing the left and right sensitivity fixed this. I even put it back to the highest sensitivity after it started working again and it was still fully functional. If anyone else notices that, just change them, confirm its working and then put it back to your desired setting.

The systems vibrate (non pro model) is much weaker than it could be. I also noticed it was much stronger on my previous ROM than OOS. Would love to see this ROM also approve on what OP didn't.

when 3rd party GApp package man agers (like nik g) finally have a decent amount of revisions specifically for A12 ROMs, I would love to have a gapps optional release.

Hope this doesn't come off as just comolianing, more of suggestions and reflections of personal desires. I wouldn't even comment if I didn't love it, 'd just go to a different ROM.

As for rhe a12 experience, there's a lot to like like the UI size adjustment in the quick settings, but there's also. a lot more Google nonsense. I didbaled the live captioning app, the local compute app and the ai prediction l/personalization nonsense. Google gunna google, at least its easily removalable than when Apple apples.

Edit: whats with no custom icon support? not in settings or in the launcher itself (except "themed" icons.) I cant recall the las time ive experienced such a thing. on android. Even Weirder, there is two different entries/ways to change the system icons.

"System Icon Packs" - wallpaper and style

"icon pack" in customization

I have to assume the 2nd one was meant for system icons and someone just misunderstood. either way, with how great monet is, this is kinda sad.
[OnePlus 9 Pro] keebfox:
This is a great rom, I have been testing it the last few hours and am really liking it so far! Here are a few things I noticed:

Location access indicator in status bar shows a lot of times (when google play services, etc is using it) Is there a way to disable this?

Google weather widgets on the home screen only show "Location permission needed", and when tapping it, it only opens the weather app with no way to give it permission.

Is there a way to get Pixel wallpapers?

Thanks so much!
[OnePlus 9 Pro] break.cold:
Answer to your question 1.

Setting>DerpSpace>Miscellaneous>Scroll Down>Turn Off- Location Privacy Indicator.

Answer 3.

Download from Play Store for Now.
[OnePlus 9 Pro] keebfox:
Brilliant, thanks!

Two other things I have spotted:

1. When using 24hrs clock the number gets cut off, I've added a screenshot.

2. Some apps show blank icons when using themed app icons after opening them. Such as Google rewards or Gcam
[OnePlus 9 Pro] break.cold:
Answering to your question 2 first.

As you are aware this is custom rom and not 100% stable. Even official from Google A12 is not 100% stable, themed app feature in style/wallpaper is on beta and not fully functional. I also having that problem with few apps.

Answering to your question 2.

Try changing your setting in DerpSpace>Statusbar.
[OnePlus 9 Pro] keebfox:
Yeah absolutely:) I appreciate it! Haven't seen it reported before so want to let the developers know!

And so far I've been enjoying the ROM a lot, it's such an upgrade compared to OOS12 :D
[OnePlus 9 Pro] break.cold:
I agree this rom is great. But battery life isn't the best. I even tried changing few kernel settings with FK app but it didn't work. Hope next update will fix this issue of battery drain.

I am huge fan of custom roms, kernels, root etc. That's why I bough OP9Pro, because it is a lot easier to customize and install roms, kernels etc.

But recently I regret buying OP9Pro because Oneplus have merged with OPPO and changed almost everything. The new ColourOS A12 is crap in my opinion and also they have removed support for custom kernels and roms. As OP9 user we know Oneplus have blocked some functionality of sensor of camera to be used with Gcam and plus they also have stopped given out sources for kernel for developers to build custom kernels.

I really don't like what Oneplus is doing, they are backing off from their strategy and plan.
[OnePlus 9 Pro] DiogoPdC:
Im making backups on everything to get ready to use this ROM

Its been years since I installed an ROM and Im a bit anxious but at the same time I see how much work y'all being putting into this project so let me buy a beer for the whole team!
[OnePlus 9 Pro] Leon2504:
Worked for me on StagOS (A12), used v4a without problems, JamesDSP worked for me too but on derp it doesnt
[OnePlus 9 Pro] keebfox:
I also bought my OP9 Pro because of the great specs, clean android with personalization and possibly to easily mod it.

I hope that OOS camera can come to this ROM at some point like I read in the first page comments. I've also noticed Gcam has some weird quirks like needing to reload when switching lens Vs OOS can smooth transition etc.

I had a nexus and my first OnePlus One was awesome.

Has anyone had trouble with wifi not turning on. I go to turn it on and it never comes on. Just switches itself back off after a few seconds. Mobile data works just fine.

[OnePlus 9 Pro] SK#Tech:
Hey guys i am on StagOS and i want to install this rom so i should follow the full instructions or just format data and sideload the rom please if anyone has the info let me know
[OnePlus 9 Pro] break.cold:
If you are on StagOS, you can move to DerpFest rom without issues. Changing roms required to factory wipe/data wipe through recovery and then install rom. If you don't do factory wipe/data wipe you will face problems and might not boot into system.

Use recovery provided by the developer of DerpFest in front page and do factory wipe and install rom and enjoy.
[OnePlus 9 Pro] shaiknbaik:
Did anyone else have issued with while adb sidloading it would fail to push at 47%? I am on the T-Mobile version maybe that's it?
[OnePlus 9 Pro] mattie_49:
You can sideload over

No just keep waiting it will boot back into recovery when finished.
[OnePlus 9 Pro] shaiknbaik:
I'll try it again tonight, after it failed I would get an error in the terminal stating it failed but I'll try again and get the actual error 🙂

I am getting ''E: Package is for product lemonadep|OnePlus9Pro but expected lemonade'' wtf is that even supposed to mean,

Edit- I did MSM, then flashed provided recovery, flashed partitions, everything done in well organiseed manner, stilll facing this issue,

also in my bootloader its showing product name- lahaina.

whyy..??
[OnePlus 9 Pro] mattie_49:
You have the wrong build downloaded. If your pro you need lemonadep/ regular 9 is lemonade
[OnePlus 9 Pro] jagratsharma:
I wish I was that stupid, So that I can enjoy this rom.

But no the package is correct.
[OnePlus 9 Pro] mattie_49:
Are you sure you have correct adb and fastboot drivers and environment set-up? Move build.zip to a different place instead of maybe just a folder on desktop. Minimal adb and fastboot folder, In address bar there pull cmd window? You using windows power shell or cmd window?
[OnePlus 9 Pro] jagratsharma:
Yea actually my wishes of being stupid came true as I was flashing the recovery of lemonade instead of lemonadep,

But all things aside I am now enjoying this rom only one feature is missing i.e. - Swaping the placement of volume control UI as it's opposite to actual buttons.
[OnePlus 9 Pro] mattie_49:
Good deal. And it's in settings.
[OnePlus 9 Pro] jagratsharma:
Can you tell me where. Edit: found it
[OnePlus 9 Pro] frost_icewind:
Is something wrong with the charging numbers displayed on the AOD when rapid charging?

They seem unrealistically high...
[OnePlus 9 Pro] MrSinister:
It's normal and there's no error. Just wait for some more time or you can check status on your device
[OnePlus 9 Pro] keebfox:
I've also noticed this. For me it seems like the time always says about 1h 24 mins left until full
[OnePlus 9 Pro] applyscience:
i JUST came here to talk about this. its not even rapid charging. im pretty sure the charging is not showing incorrect times but actually just incorrectly charging. i assumed it was a battery life/longevity option with the incorrect defaults allowed to pass though but im not seeing anything easily identifiable to make it quick charge again.

anyone try that evolution A12? I ask because its impossible for me to ID Android 12 issues or just ROM issues, as this is my first A12 experience. maybe theres a 12 setting im just missing.

Ill probably jump on Evolution just to compare. if it resolves my icon gripe and this charging situation, ill probably park there for a bit.
[OnePlus 9 Pro] hallo dare:
It's the same for every custom rom as far as I'm aware
[OnePlus 9 Pro] IamTheBRAVE:
Due to Oneplus ultimate wiseness, the time left until charged is hardcoded in the device source code. It's set to 5000ms (1h24mn). It's better to use a battery monitor app to view the real data while charging (mainly how much watts it's charging)

I personally use BatteryGuru. It's got a couple of nice features including a custom doze feature.
[OnePlus 9 Pro] IamTheBRAVE:
This is not a rom problem. You'll have the same charging data ( current, voltage, watts, charging time left) on all roms/android versions Oneplus made that data fixed instead of being dynamic. No need to switch roms
[OnePlus 9 Pro] keebfox:
No way 😂 I was already wondering why it never updated! Thanks for the insight though.

Do you know if it's possible for ROMs to display the real data (in an update I assume) similar to battery monitor apps on the lockscreen?
[OnePlus 9 Pro] IamTheBRAVE:
It would depend on rom devs to do it. It should be possible on custom roms also maybe a mod magisk module could achieve that too.
[OnePlus 9 Pro] keebfox:
Sorry if this sounds like nitpicking, has anyone else also faced micro stutters or frame drops when navigating the launcher or closing apps? On the home screen and closing apps it is very noticeable because it usually happens during the swipe animation where it stutters for a very brief moment.

Here is a screen recording: https://drive.google.com/file/d/1qqRMb2reTnzND7YuuW4nk8KvRogXgnJy/view?usp=sharing it captured the stutter pretty well.
[OnePlus 9 Pro] TheKnux:
Why not just use the current mA in status bar so you don't have duplicate battery percentages? To each their own, but that would bother me. 😂
[OnePlus 9 Pro] TheKnux:
I was on Xtended and it had the same issue. It does indeed Warp Charge though. Every time I plug my phone in on OOS, no matter what the percentage, it would say "less than 24 minutes remaining". It took about the same time while on Xtended as well.
[OnePlus 9 Pro] mrgwin:
it DID charge with Warp Charge on compatible adapter, it might said 1hr 24 min but it actually warp charging

and yes Evolution X, XTENDED all has the same issue
[OnePlus 9 Pro] oscarmaldonado:
That's normal bud, even European, Chinese like my case or Indian versions do the same thing, just let your phone do the rest.
[OnePlus 9 Pro] jagratsharma:
I didn't even notice it, now I can't unsee it.
[OnePlus 9 Pro] IamTheBRAVE:
Have you tried other launchers (nova 7 is great) i never had any stutter on any rom even stock. Could be the 120hz refresh rate, are you using that? Try setting both min and max to the same rate.

Could you share how you do it? I'm on stagOS now so don't know if i have it available.

Also, i use the battery persistent notification in lockscreen to stop the Big clock from showing.
[OnePlus 9 Pro] TheKnux:
Here you go!
[OnePlus 9 Pro] :
Beautiful
[OnePlus 9 Pro] IamTheBRAVE:
Lol, never noticed that. Thanks
[OnePlus 9 Pro] applyscience:
But why did this start now? I went directly from crdroid, where this worked just fine, to this. it can't be anything lingering from OOS.

Of coursre that raises the question of could ROM jumping the way I did somehow cause it? I can't imagine so but I am also not a battery expert.

Edit: per the image attached, things seem to be working now. I didn't change cables or anything. I did notice it took About 30 seconds to reach the mA and mV shown.

Either way, my phone has gone up 12% since starting this quick message. I'll uninstlal accubattery (just installed to test right now) and hope it yields the same results. Can't imagine it won't.

[OnePlus 9 Pro] frost_icewind:
I used the rollback package, then I followed the instructions in the first post.

The rom is stable. Battery life isn't the best, but the experience is good. Install a gcam and you should be good.
[OnePlus 9 Pro] frost_icewind:
All I'm saying is that the the stuttering started after WebView updated. It stopped after I rebooted.
