I'm stuck on fastboot menu, I have enough after 6 hours of trying :(
[OnePlus 9 Pro] break.cold:
Maybe at your end. My works fine. Maybe it WhatsApp's connectivity issue from server side. It happened to me once with StagOS then it working after few hours of wait.
[OnePlus 9 Pro] break.cold:
What phone do you have Oneplus 9 or 9 Pro? And which country model?

Are you sure you have downloaded right file? For series 9 and 9Pro
[OnePlus 9 Pro] break.cold:
Ok, I will share it.
[OnePlus 9 Pro] Evo609:
Oneplus 9 Pro EU, LE2123

I'm downloading files provideded in this link https://sourceforge.net/projects/derpfest/files/lemonadep/

Double checked.
[OnePlus 9 Pro] break.cold:
What rom you are using right now?
[OnePlus 9 Pro] Evo609:
Right now I'm on A11 OOS 11.2.10.10.LE15BA
[OnePlus 9 Pro] break.cold:
Try this Platform-tool.

1. Install recovery: fastboot flash boot file name.img

2. Reboot to recovery

3. Choose option factory wipe/data wipe

4. copy-partition zip in adb sideload (if you want but recommended)

5. Reboot to recovery again after copy-partition zip from adb sideload

6. Install rom through adb sideload file name.zip

7. After successfully install rom factory wipe again (recommend)

First make sure drivers are installed properly.
[OnePlus 9 Pro] Time of Awakening:
Well it is a problem with the Spamfilter for calls. I don't know why? But after deactivating it is working. By the way, switching the mobileconnection to Globalsettings brings more speed and stability.
[OnePlus 9 Pro] Evo609:
Fastboot flash boot_a name.img and fastboot flash boot_b name.img

or just fastboot flash boot name.img?
[OnePlus 9 Pro] Aleplus:
I would really like to see the voice change function as in Oxygen OS 12, as well as be able to use the stock camera Oxygen for OnePlus 9 Pro
[OnePlus 9 Pro] JohnTheFarm3r:
The stock camera doesn't exist for Custom ROM's.
[OnePlus 9 Pro] unloseking2500:
Hey guys, I can't root the phone with the newest updated ROM. I tried the magisk v23.zip but nothing changed afterwards. I also tried the newest version of Magisk 24.3 but. It was rooted successfully. I have root. BUT google apps keep crashing, eg. Gmail, photos, g-keyboard, chrome, etc. They are all up like 2s then crash. I have to uninstall the Magisk completely then everything becomes normal.

What can I do?

I was rooted with the March version of ROM.

Side note:

I flashed recovery, ROM, and root on BOTH slot a and b for ONLY this April version when I installed it this time.
[OnePlus 9 Pro] Aleplus:
On the 8th series Oneplus in the custom firmware somehow implemented the operation of the stock chambers from oxygen, at least from the 11th version of oxygen os
[OnePlus 9 Pro] Aleplus:
Has an oxygen os chamber already appeared?
[OnePlus 9 Pro] JohnTheFarm3r:
That doesn't change the fact that it doesn't exist in OP9 Series.
[OnePlus 9 Pro] Aleplus:
Has anyone tried to put a camera from 11 Oxygen OS on series 9?
[OnePlus 9 Pro] JohnTheFarm3r:
Try it, and let us know. Thanks.
[OnePlus 9 Pro] Aleplus:
I just have oxygen 12 at the moment, but taking into account the fact that cameras from 11 oxygen are used on series 8, this should work on series 9, respectively.
[OnePlus 9 Pro] JohnTheFarm3r:
Good luck.
[OnePlus 9 Pro] BDProductions:
the 8 Pro uses a main sensor IMX689.

the 9 Pro uses a main sensor IMX789.

There are other differences.

Do you just mean the camera skin, maybe?

I, too, would like the OOS 11 stock camera, if it had full access to all sensors the same as it does in OOS... but I realize most ROM developers are not prioritizing the cameras, and for good reasons generally.

What I am doing right now is carrying a Galaxy Note 20, when all I need is megapixels. 64MP gets the job done, even if color accuracy and image accuracy takes a little hit... focus is not good as you get closer to the edges from the center sharp focus...

Still more convenient than packing a DSLR or Micro 4/3 camera in your pocket, and you can easily move the shots between phones without losing details.

It's best to wait patiently if you don't have the skills needed to port the camera software yourself.

Most devs don't appreciate being told what to work on when.. and I don't blame them when they have to set some ungrateful prick straight.

It's a phone first, and in general the devs do this as a hobby instead of as a job... they all deserve some respect for not just making themselves a ROM and telling everyone else to get bent. 😉

I only donate to devs who make ROMs in line with my needs, and right now it's between DerpFest and Paranoid Android. I think in the next month I will settle on one and pony up the cash as a reward. Both promise updates soon, and that beats those other ROMs that show no progress in their forums.

It's nice to see talk of what is coming soon, and what may come after more important things are taken care of.

Many thanks to Devs, testers, XDA staff, and everyone else who isn't a whiny bee-otch. 😋
[OnePlus 9 Pro] JohnTheFarm3r:
There are a few devs who tried working on the stock cam. The issue isn't only if they prioritize it or not, but the issue lies in OnePlus and their collaboration with Hasselblad.

Lots of proprietary features, files, are closed source, and the only way is to do them from SCRATCH which is a heavy challenge even for the "best" when they're doing it from scratch, with no instructions on what files, dependencies, etc... need to be ported/modded/added...Totally blind development.

It kind of got worse the last few years with all the auxiliary lenses and each OS's own "features" which are most of the time close sourced.

For example, Xiaomi and their Miui camera, used to be "EZ" to port it over a few years back, now? Now some of them tried, but often the majority of things is broken, missing features, etc... And I can only imagine it's the same with the majority of the brands and their stock camera apps nowadays.
[OnePlus 9 Pro] BDProductions:
Where I said "other differences," that's the part you expanded on.

I know better than to think it's easy, even if someone does get the "camera" working on one model. I know that even if they unify the camera skin it doesn't mean the cameras are handled the same between models.

I don't think Hasselblad optimizations are the big part. Even without their processing algorithms, raw access to the IMX sensor @ full resolution should be possible, even if it meant the images were unprocessed, which would be fine for many uses, and for post processing in another app.

Similarly, I find that shooting video in 8K 30fps yields a wider depth of field when outputting 4k video than shooting in 4k in the first place would.

For now, I have a work around using a second device. It does not matter to me which device I run stock or with a 3rd party ROM, because my employers call me on my Google Voice # anyway, and both devices ring.

Since I need more photos than video, I run a stock Galaxy Note 20 right now, along with PA on my OnePlus 9 Pro.

I am hopeful some Dev figures out how to expose the 48 and 50MP sensors at full resolution at some point, but I CAN live without it for now.

@ekin_strops : I take it you were expanding on my general message to others that the cameras use different hardware between the 8 Pro and 9 Pro, and asked Aleplus if he meant the Camera App, or just the interface skin.

I understand the camera access is a proprietary blob that only exposes 12/12.5MP images to 3rd party camera software. In OOS it's supposed to expose more via Camera2 API. I don't recall if that was the case using Open Camera with the Camera2 API selected, but it did allow cycling through the lenses including the little black and white sensor.

Officially have been running PA for 24 hours now. @ 50% battery remaining. (fairly obviously running black themes everywhere)

Pretty happy with efficiency and performance of PA.

Looking forward to the expected 1+9Pro upcoming Beta. 🥳

Expecting it will be best to do a clean install, deapite that meaning 3.5hours and 4.25GB of app installs and configurations after installing the new PA ROM.

@ Everyone else: What are the most important things to you that you would like to see fixed, besides the camera? Not talking additions or new features right now. (more of a what do you feel is currently broken that you would like fixed question)

Planning on trying DerpFest next, after giving PA a fair shakedown.

How to get rid of this notification?
[OnePlus 9 Pro] darkness4every1:
Click on the Power Share tile from status bar to disable reverse wireless charging
[OnePlus 9 Pro] imirwp:
Nothing happens when I click on it. Some other users are experiencing the same issue. I somehow used root app to get rid of this. That app is called "NotificationsOff"
[OnePlus 9 Pro] darkness4every1:
Click it a few time untill it works

[OnePlus 9 Pro] maksimal-nn:
I also had a similar problem, the error was in the old recovery from 2022-01-30, downloaded boot(lemonade).img dated April 16 and everything was successfully installed.
[OnePlus 9 Pro] RawR Cheeze:
Did you ever find a solution to this issue? I started experiencing a issue today where it seems like the system UI is crashing and restarting forever, essentially making it unusable. Had ran previous updates without any issue. No problem running latest update since release date otherwise.

E: multiple factory resets does not solve the issue.
[OnePlus 9 Pro] tuga49:
@Ledrock When an app gets updated by the Play Store, if the app has AppLock enabled, it losts it and after Play Store updates the app, I need to re-enable the AppLock for that app again, otherwise I can open the app without security code/fingerprint. Please try fix it on next build, since this is a security issue... Thank you for the great ROM!
[OnePlus 9 Pro] ezpz.MiDAS:
Did anyone else have signature failure with Magisk 24.3? Fresh install. Had a prompt to install anyway and it seemed to go through, though initial startup has been hanging for 10 minutes.

Edit: And now when trying to redo the installation i get installation failures "Package is for product lemonadep, Oneplus9Pro but expected lemonadep" - No ****, i have OP9Pro... Do i really need to MSM to fix this?...

Edit2: Tried multiple different options and simply cannot get this rom to install.
[OnePlus 9 Pro] ezpz.MiDAS:
I finally just installed the previous version and updated via their OTA. What a ride...
[OnePlus 9 Pro] razercortex:
Try clean installing by running your MSM, upgrade to the latest OxygenOS 11 version possible, then extract the ROM zip and the payload.bin, flash the boot.img, then wipe data first and then adb sideload the entire ROM.
[OnePlus 9 Pro] Elrey567:
I had same issue messed with it all day, at the End I just flashed CR Droid
[OnePlus 9 Pro] JohnTheFarm3r:
Try next time flashing the included Boot.img. as instructed by the instructions. There is a reason why it keeps being updated.
[OnePlus 9 Pro] Elrey567:
I flashed the boot image he provided when he first announced the update, how about instead of just going around quoting people and being a douche on each thread you just don't say anything without knowing
[OnePlus 9 Pro] razercortex:
Instead of fighting, you can try installing the boot.img from the ROM zip and sideloading the zip there.
[OnePlus 9 Pro] JohnTheFarm3r:
What are you gonna do about it? lol Follow the instructions, it worked perfectly fine for like 99% of the people.
[OnePlus 9 Pro] Diaze:
Coming from another rom whats the process to flash this one?

Just flash the boot recovery and then sideload the new rom?
[OnePlus 9 Pro] DonnerPlays:
Factory wipe.

Flash boot.img in fastboot (make sure to have the latest).

Boot into the recovery.

Enable adb sideload

Sideload rom
[OnePlus 9 Pro] efex:
Just wanted to comment, this ROM is awesome!

I'm diabetic and use a blood glucose sensor, libre sensor, and with stock OOS 11/12 I constantly got scan errors and had to reboot. I tried Lineage about a year ago and the sensor didn't work at all. Almost gave up and ordered a Samsung, but descided to try this a few days ago - not a single scan error. This litterally saved my device.

I also had issues with 5G on stock, when I got out of 5G coverage my phone sometimes lost data connection (didn't go back on 4G), but it now works flawlessly!

Thank you!
[OnePlus 9 Pro] vincemue:
Reboot to bootloader

Flash the provided boot.img

Reboot to recovery

Format data in the recovery

ADB sideload rom.zip

(optional) Flash Magisk

format data after flash of image.

also check if you need to downgrade to A11 first...

I used this post to flash this rom:

Hello, I also got a persistent "wireless powershare" notification even though I don't have this function on my chinese Op9.

Can't kill it in any way.

Someone got an idea ? 🤯
[OnePlus 9 Pro] SK#Tech:
Long press the notification go to app info force stop or go to settings app system ui force stop after that notification will no longer show until you press edit quick panel button again
[OnePlus 9 Pro] loulondono:
Does anyone know what a system app called "CneApp" is and why it checks my location every few minutes? Thanks
[OnePlus 9 Pro] DonnerPlays:
I think it's the DerpFest settings thing?

At least for me it pops up on most of the settings when I change them.

You can disable the location notification somewhere in the DerpFest settings (I think last tab)

(Though that disables all of them)
[OnePlus 9 Pro] .DeluXer:
That is part of qualcomm driver and checks ur wifi connection or something like this. I disabled location for this app without a problem so far.
[OnePlus 9 Pro] Diaze:
I flashed root and now my banking apps dont work. How can i fix thay?
[OnePlus 9 Pro] vincemue:
use the search function.

in magisk use zygisk and hide the app, also install universal safetyNet fix magisk module, maybe clear cache of the app (EDIT: at least that works for me)
[OnePlus 9 Pro] razercortex:
No need for the universal module
[OnePlus 9 Pro] razercortex:
Simply enable Zygisk, hide Play Store and Play Store Services (make sure to hide everything), then hide your banking app.
[OnePlus 9 Pro] DonnerPlays:
I have one banking app that somehow still detects Magisk.

For that app I have to uninstall the app, then it works (even hiding the app doesn't work ...)
[OnePlus 9 Pro] Diaze:
How to enable zygisk?
[OnePlus 9 Pro] razercortex:
Go to Magisk settings, enable Zygisk there and also enable enforce denylist.

BTW, it seems like you're not familiar with how root works. If so, I would strongly recommend you to learn about it before flashing Magisk as it can be dangerous at times.
[OnePlus 9 Pro] Diaze:
Thank you for yhe answer. I made it work
[OnePlus 9 Pro] HasanMuha:

Just one request, any chance the pixel style recent text copy feature can be added to the rom? I am sure other users will find it a very useful addition as well.

[OnePlus 9 Pro] pifubaro:
Hi!

Why is the phone speaker when I connect Bluetooth?
[OnePlus 9 Pro] AlexeXt:
Yes, the same.
[OnePlus 9 Pro] XLR-U:
Yes, this is kinda problematic,

And the App Lock overlay is transparent and blurry but you still can see what's behind, sometimes it shows another app (or activity) for unknown reasons behind being blurred,

It would be nice to have the app locker behave more like OxygenOS(11).

The alert slider, when moved, ends the "Do Not Disturb" mode, so when I want to set the phone to vibrate, it ends my active schedule for the night. It isn't like that in OxygenOS, it would be nice to improve that.

Otherwise this ROM is great 😃
[OnePlus 9 Pro] XLR-U:
It would be nice to have a way to show hidden apps in the app drawer, like a keyword in search or a specific move in the app drawer.

Last option on the list
[OnePlus 9 Pro] loulondono:
I have looked just in case I missed it. No reverse wireless charging. No OOS camera, don't think any ROM has that. As for Dolby Atmos, not natively but there is a magical module for it from the razer 2 if my memory serves me correctly. Have not flashed it so cannot say whether it works or not
[OnePlus 9 Pro] Spidermonkeyj75:
Wish you had a rom for the 10 Plus 5G
[OnePlus 9 Pro] novo2o:
Reverse wireless charging is present in the available quick settings tiles, I tested it on OP9pro and can confirm it works fine yet I'm having a bug with the tile which show RWC always off unless I remove it and add the tile again. But again it does work.
[OnePlus 9 Pro] loulondono:
Yes you are right I just searched in settings, forgot the term power share. My bad

Hello, could someone please give me some info about this rom? Does this rom support 120hz? Also is the movement/scrolling smooth and push notifications works without any bugs? What about camera? is it in same quality as it is on OOS12?
[OnePlus 9 Pro] GolovaRaoul:
You could have found this by scrolling through the posts ;)

Yes it does support 120Hz

It's smooth if you use some FKM tweaks which you can find on one of these pages (to lazy to link it, use the search button)

I use a GCam which can also be found on the OnePlus 9 Pro xda forums, its not the same quality unfortunately but it does the job for me. A dev from another ROM mentioned he's working on bringing OOS cam to android 12 roms but it's not ready as we speak

[OnePlus 9 Pro] loulondono:
What work exactly. Don't all these various developers take this and that from each other, building what they have in mind, and then credit each other?

Also, if we're no longer getting any updates, what now? This is a good ROM but it is by no means bug free nor "complete". How long before there are security implications for users?
[OnePlus 9 Pro] DonnerPlays:
Based on what I read its because DerpFest is not open source (or at least not fully) so the argument is that DerpFest devs can "steal" from others like crDroid but they can't use anything from DerpFest.
[OnePlus 9 Pro] loulondono:
Oh... Yeh that's ****. Very unfortunate, I did some research not too long ago and derp was regarded as the go to, sorry to see it go. I know I should probably wait to see what people now switch to before re doing my whole set up seeing as there is no urgent need, but knowing myself I will probably switch to crDroid after work tomorrow. Hopefully that works as well as derp, I like as much customisation as possible and I've had a few issues with Stag.

Also upon some thinking, what "USP" as it were does derp even have, other than maybe the launcher? It all seems ripped from various other ROMs I remember using in the past, just in a very stable package with no major issues.
