[OnePlus 9 Pro] Zhono:
For anyone looking for recommendations to switch to, I ended up moving to Nameless AOSP https://xdaforums.com/t/rom-official-oneplus-9-pro-12-1-0_r5-nameless-aosp-2022-05-14.4403301/

It doesn't have most of the customizations options like what there is in the Derp Settings menu, which kinda sucks. But everything that was broken for me on Derp(USB data to PC, fast charging, live wallpapers soft-bricking the device, no ringing when you place a call, etc), all work fine. And while I was having TONS of rom crashes on Derp, I haven't had a single crash so far.

I didn't have to revert to stock or anything like that. I just flashed the Nameless boot.img to both slots, then booted into recovery, did a factory wipe, then flashed the rom to both slots, then booted up. After I restored my backups through Google and setup my apps and accounts, and booted back to recovery and flashed the latest Magisk to both slots, and I was good to go. Their recovery has a "switch slots" button to make it easy to change between slot A and slot B, without having to use fastboot.
[OnePlus 9 Pro] acloh0411:
How to flash boot.img to both slot from derpfest to nameless?

All others said must downgrade to OOS11 before u can switch from derpfest to Nameless, is not true?
[OnePlus 9 Pro] Zhono:
I did exactly the steps I listed in my post. I downloaded the boot.img from Nameless, flashed it in fastboot, rebooted to recovery, factory reset, flashed Nameless rom, booted the rom and setup my apps, went back to recovery and flashed Magisk. That's it.
[OnePlus 9 Pro] acloh0411:
so no bootloop when u switch direct, not as most ppl said must downgrade to OOS11 first, then....?
[OnePlus 9 Pro] vincemue:
as I understood, this is only required, when you are coming from OOS12.

maybe also just to be safe, so if it goes wrong, downgrade first.
[OnePlus 9 Pro] vincemue:
let me know how it goes, and if you find any big difference.

I am also interested in crDroid as I have the feeling this is the most active ROM.
[OnePlus 9 Pro] rejectedjs:
I personally really enjoyed crDroid but there was a really irritating bug with the ROM where I kept having to press power 3-4 times every time to get the lockscreen to show up on my device. Eventually it ended up making me call 911 somehow and that's when I decided to switch over to Derp. This was about a month ago. Derp has way more customization features than crDroid so I'm a bit sad to leave it. But I'm not sure whether to try CrDroid again or switch to Nameless.
[OnePlus 9 Pro] loulondono:
Derp has more customisation than crDroid? That's a shame. I thought crDroid was a newer re skin of Resurrection Remix, basically a all out customisation ROM. I've found customisation in derp quite lacking if I'm being honest. Better than Stag I was on previously, but nothing like the custom ROMs of old
[OnePlus 9 Pro] TheKnux:
Nameless or bust. 😎

Old RR user and ex-ROM builder here lol
[OnePlus 9 Pro] BDProductions:
Paranoid Android is good with reasonable customization. Very stable.

Been my daily driver for over 6 weeks now.

Cosmetic issues, mostly.
[OnePlus 9 Pro] loulondono:
I went the crDroid route, only one day usage mind you but so far I am very happy with it. Can't speak about stock kernel tho, flashed arter97s immediately and have been very happy with the performance
[OnePlus 9 Pro] kevinleo10:
any scroll lag?
[OnePlus 9 Pro] benhidalgo:
yes
[OnePlus 9 Pro] acloh0411:
in the switch slot i did click the slot B from my active slot A but the active slot is not change in recovery mode, so is second time flash rom will go to slot B?
[OnePlus 9 Pro] Zhono:
After you choose switch slot, you have to reboot back to recovery for it to take effect.
[OnePlus 9 Pro] loulondono:
That was one of the reasons I stayed away from crDroid and went derp, there were various issues being complained about. However, I have experienced none of them. Everything is fast, snappy, smooth as butter and no stutter or lag in sight. Closest thing that came to disappointing was the battery life, as it was draining faster at the start of the day but progressively slowed down. I got 5½ hrs sot with a stupid amount of standby, granted that is aided by naptime but phone runs and gets all the notifications it would promptly.
[OnePlus 9 Pro] GolovaRaoul:
I have around the same stats. I gave up trying to fix the battery usage of the phone and accepted these stats
[OnePlus 9 Pro] loulondono:
Yh apparently people on the arter thread have wayyy batter battery life. I'm at the point where I've done enough tweaking for it to last all day as much as I need to use it for whatever I want to do that day so it's fine. I am a bit worried that I hurt the battery too quick by using fast charging quite often when I first got it, but if I stick with this phone for years and years I'll just send it to OnePlus for a battery replacement once it stops meeting the all day mark
[OnePlus 9 Pro] IamTheBRAVE:
I'm no expert but it looks like your device does not doze when screen turns off.

Awake time with screen off is too high. And your screen off doze is 0% time.

I'm on crdroid, btw. My awake time is 2m. I use batteryguru app which has a doze tab to set it up (works well by default too). Battery charging habits matter too.

My SOT is 5hrs too cause i play a couple of heavy battery draining games. But otherwise it can reach 7½hrs easy. I think my device is not performance throttled and the SOC and battery heat up a lot during hot weather. In winter, battery temp never went past 35⁰C nows it's goes over 42⁰C.

I never tried flashing a custom kernel on this device. I'm afraid to mess it up (happened with an old tab of mine, the battery died after a while cause soc was stuck in perf mode) does it work well by default or did you have to make modifications?

Out of the few roms i tried ( StagOS, Nameless) crdroid felt the best with the most customization options.
[OnePlus 9 Pro] loulondono:
No tweaking required apparently, I just added naptime because my stats were not looking like the other ones so I was playing around with battery stuff. I could get 6-7 hrs, but my standby would be nonexistent, or have my phone available but get less sot. Once I used naptime, that stopped being a problem, tho I haven't experienced idle drain in the decimals like others have. Arter works very well, the latest stable is the smoothest android experience I have ever had, but watching Netflix causes a phone crash. I have had a good time with the alphas tho, can't wait for the next stable release. Just make sure you backup the relevant partitions, or you will end up with a bricked device sinner or later

As far as doze is concerned, could it be that I am using light doze rather than regular doze, so it doesn't wake up when it gets moved? Otherwise I don't know why it doesn't doze, it really should and the idle drain has gone down considerably, I've done a/b tests. Also ever since going to android 12 and using a ROM that doesn't crash once every 24hrs like clockwork, I have neevr had my phone go anywhere near that temperature, no matter the scenario. Is that normal temperatures?
[OnePlus 9 Pro] IamTheBRAVE:
No, really not and i'm worried it'll have an impact on my phone in the long term... I do have frequent Qualcomm crashes and freezes. I plan on msm-ing back to stock at the end of this month to clean flash a 12L rom again. Wish me luck🤞
[OnePlus 9 Pro] loulondono:
Yh give it the factory reset treatment on the offchance something goes tits up... hope it goes smoothly. On the plus side, you still have your warranty!
[OnePlus 9 Pro] applyscience:
so this guy just quit? lol damn. i was wondering why my phone was getting so awful
[OnePlus 9 Pro] Atul Menon:
Rom is dead, dint you see derp announcements.
[OnePlus 9 Pro] AlexeXt:
Bad(

Was the best ROM. Can't find replacement.
[OnePlus 9 Pro] dyscostic:
lmao what's the point of melting down about sharing code if you're not going to do any releases of your own code 🙄🙄🙄
[OnePlus 9 Pro] applyscience:
Would I be asking if I did?
[OnePlus 9 Pro] JohnTheFarm3r:
It's not this guy only, it's the actual guy who was working on derpfest base. So, it's expected that devs will abandon Derpfest project.
[OnePlus 9 Pro] hagar006:
Shame.. good rom this and still running it as I've not really found a replacement yet 😏
[OnePlus 9 Pro] vsinha71:
while flashing the boot(lemondep).img error message lemonadep is not recognized in powershell. can i rename and flash. thanks
[OnePlus 9 Pro] Samuel Holland:
You could rename but if I'm not mistaken it should work long as your in the folder with the boot.img like cd Downloads(or path) then fastboot flash boot boot.img

Copy and paste should work also.

I'm sure you already know fastboot devices

will list your device if everything ok👍

I hope this could help. Also if nothing else you can copy path of folder with fastboot in it while placing file you want to flash in Fastboot folder if fastboot/adb isn't universal. There is guides and tools here on XDA if that would need to be an option. I'm sure you knew most of this but I wanted to give a complete answer just in case you or anyone else was wondering.
[OnePlus 9 Pro] vsinha71:
thank you so much for your help. just that it was the first time i got such an error so was not sure. it worked.
[OnePlus 9 Pro] vincemue:
just to be sure: you know that it seems that there is currently no development ongoing for this rom?
[OnePlus 9 Pro] hagar006:
Update your powershell to latest version and it will work..
[OnePlus 9 Pro] JohnTheFarm3r:
Don't use Powershell. Use ADB Platform-tools, directly from the google website. Latest ones.
[OnePlus 9 Pro] vsinha71:
Yes am aware. Just wanted to try it. Thanks
[OnePlus 9 Pro] vsinha71:
Thanks was able to flash.
[OnePlus 9 Pro] vsinha71:
Thanks it worked.
[OnePlus 9 Pro] prateek978:
nameless os
[OnePlus 9 Pro] hagar006:
Tried nameless.. not my thing but bliss rom is a bit like derp so stay with that for now..
[OnePlus 9 Pro] metbed:
does this ROM have OOS Camera app?
[OnePlus 9 Pro] Barsky:
I know this is not rom etiquette, but I'd love to get back on your rom. Any idea of when an update might be hoped for? (I know you have life outside of roms. No pressure :)
[OnePlus 9 Pro] alb94:
Not. unfortunately we still don't have the oos cam for series 9.
[OnePlus 9 Pro] Zhono:
Never. The dev is no longer developing the rom.
[OnePlus 9 Pro] Iqbal55555:
Does this passes safety net? Any problem of distorted sound from speakers while listening to media at full volume?
[OnePlus 9 Pro] JohnTheFarm3r:
This ROM is EOL.
[OnePlus 9 Pro] vincemue:
depends
[OnePlus 9 Pro] Iqbal55555:
Depends??? How does that work?
[OnePlus 9 Pro] vincemue:
depends on if you configure it correctly and install correct magisks modules.

but as @ekin_strops mentioned, this ROM is not beeing developed anymore
[OnePlus 9 Pro] Iqbal55555:
I don't use magisks.
[OnePlus 9 Pro] vincemue:
perfect, thanks for letting me know.
[OnePlus 9 Pro] Iqbal55555:
Is it mandated to use magisks for installing this rom? Other custom rom doesn't require it though.
[OnePlus 9 Pro] vincemue:
no its not, but you asked how to pass safetynet...
[OnePlus 9 Pro] Iqbal55555:
Doesn't the rom come with default safety net checked?
[OnePlus 9 Pro] vincemue:
ok bye
[OnePlus 9 Pro] Iqbal55555:
Seems like you are not aware of the thing. Install Nameless you will get to know. Take care!
[OnePlus 9 Pro] stez827:
Take like 5 seconds to look at the features list and you'll see that one of them is passing safety net
[OnePlus 9 Pro] Iqbal55555:
It says hack to bypass. But what about privacy level for sensetive data? Why to bypass? If there is option to fulfill the criterion of the safety net.
[OnePlus 9 Pro] stez827:
You can't "fulfill the criterion" of safetynet with an unlocked bootloader
[OnePlus 9 Pro] Iqbal55555:
Got you. That every custom rom is bypassing the system of safety net i guess.
[OnePlus 9 Pro] stez827:
Yep and it's not a good idea to flash this rom since it is no longer being maintained
[OnePlus 9 Pro] Iqbal55555:
What's your take then?
[OnePlus 9 Pro] stez827:
Flash another room like nameless or lineage
[OnePlus 9 Pro] Iqbal55555:
I have tried Nameless for like a full day but the thing is that it has an annoying bug of distorted sound which I personally can't effort to avoid as it may damage my speakers. Else everything seems flawless if we ignore a bit here and there.
[OnePlus 9 Pro] JohnTheFarm3r:
The sound issue is not gonna damage your speakers, it's just a distortion.
[OnePlus 9 Pro] Iqbal55555:
No it's not. Try to pay close attention you will get to know that the speakers can't handle bass because of which it produces distorted output. Just Lower your volume to the level where the sound becomes normal and then observe by increasing it slowly.
[OnePlus 9 Pro] JohnTheFarm3r:
The speakers are NOT being OVERDRIVEN. The sound is just distorted and the amplifier DOES NOT supply MORE power than a SPEAKER can HANDLE.

It's a distortion due to the amplifier being pushed more than it can, which results in nothing else than a simple distortion. It doesn't physically push more power to the speakers.
[OnePlus 9 Pro] xontax:
Problem with nameless:

- auto brightness doesn't seem to work, extreme Display battery consumption

- extreme battery drain even with gms doze and naptime (nocustom kernel for A12)

- sound cracklings
[OnePlus 9 Pro] stez827:
Why are you posting that here instead of on nameless page
[OnePlus 9 Pro] xontax:
Because I was looking for a A12 custom rom and figured out that there is no good solution. People were talking about nameless here
[OnePlus 9 Pro] JohnTheFarm3r:
People were suggesting nameless, but that doesn't mean you should keep posting bug reports in this thread. lol
[OnePlus 9 Pro] Mr Hassan:
where,s the provided boot? for twrp?
[OnePlus 9 Pro] golfgtiedition30:
In the download folder. This rom is not being maintained anymore either.
[OnePlus 9 Pro] Mr Hassan:
In downloaded folder only have rom zip

And zip have boot

But idt this boot have twrp
[OnePlus 9 Pro] EtherealRemnant:
TWRP isn't used on OP9. It doesn't work right with OOS11 and it doesn't work at all with OOS12.
[OnePlus 9 Pro] Mr Hassan:
According to op

Flash provided boot to get twrp

Or then flash via adb rom

Ok you tell me how can i flash this rom?

And also i need google rom os12 for op9 pro if available there
[OnePlus 9 Pro] vincemue:
do not flash this rom, because it is not maintained anymore.

dont ask questions about it, it makes no sense.

everything is outdated and you are wasting everybodys time
[OnePlus 9 Pro] EtherealRemnant:
It says nothing about TWRP.

INSTRUCTIONS

Make sure you are on latest OOS 11 (11.2.10.10)

Reboot to bootloader

Flash the provided boot.img

Reboot to recovery

Format data in the recovery

ADB sideload rom.zip

(optional) Flash Magisk

Reboot and voila!

You flash the posted boot image which comes with a custom recovery and use adb sideload to flash the ROM with that custom recovery. What aren't you understanding?

You shouldn't use this ROM though as it's been discontinued. Upgrade to OOS12 C.48 and use StagOS or Nameless or another one of the OOS12 firmware-based ROMs that's still being maintained.
[OnePlus 9 Pro] z00man:
So it seems theres no one to continue developing this custom rom..hopefully we see someone will one day🥹
[OnePlus 9 Pro] stez827:
Honestly nameless is way better more stable and more frequent updates (weekly ish) It would be cool to see it come back but it's not a major loss
[OnePlus 9 Pro] z00man:
tho i was 8t/nameless lately a long time which was really stable, for 9 pro its not yet imo
[OnePlus 9 Pro] jhr5474:
I am confused, i cant find sideload adb in recovery, is this twrp recovery? i dont see a stock one, when i tell op9pro to boot recovery it just reboots, this is even after msm tool

any ideas?
[OnePlus 9 Pro] stez827:
Don't use this rom it is outdated and no longer being supported also you need to flash recovery not boot recovery
[OnePlus 9 Pro] Shooter7889:
You need to extract boot.img(if u don't have it) and fastboot flash boot "boot.img" then used buttons on phone to boot to it.
[OnePlus 9 Pro] Iqbal55555:
Does the support for this rom resume? Heard about that.
[OnePlus 9 Pro] Samuel Holland:
I hope so
[OnePlus 9 Pro] JohnTheFarm3r:
It won't. The developer is "retired". Not sure where did you hear such thing.
[OnePlus 9 Pro] lev.sagal:
Does someone having issue with brightness on the latest version? I tried to change all setting related to brightness and display but still see artifacts like abrupt change of brightness even nothing changed. I tried to off auto brightness settings but it didn`t help me.
[OnePlus 9 Pro] vincemue:
:rolleyes:
[OnePlus 9 Pro] jiframnes:
Do bank services work? I havent been installing custom roms since the galaxy s2 and Note4. Bavk then , this things didn`t work and no streaming services either.
[OnePlus 9 Pro] Samuel Holland:
There is a setting that sets it upon screen turn on instead of auto brightness. Just thought I'd mention. I set it manually a lot of times if too bright or to dim.
[OnePlus 9 Pro] Samuel Holland:
Yes, everything is working for me. It's worth mentioning that while my bank app, something with cash app when I use only allows me to accept requests. When I try to pay myself it says success and then error. My bank app won't work with usb debugging on under dev options on so u have to disable this since it comes on by default.
[OnePlus 9 Pro] lev.sagal:
If you mean Google Pay in this case the answer Yes
[OnePlus 9 Pro] lev.sagal:
My issue little bit different. For instance when I am scrolling feed on Twitter and I read some twit (stopped scrolling feed) the screen becomes a little bit darker but when I touch the screen again the brightness returns to the previous state.
[OnePlus 9 Pro] Samuel Holland:
It's not related to screen timeout by any chance? (The screen dim before it goes off), you can set the timeout to a higher time like two min or five min? I don't have this issue, although I'm running Arter kernel if that makes any difference.
[OnePlus 9 Pro] lev.sagal:
It`s not related to screen timeout because it becomes darker in a few seconds (timeout set to 1 minute). And it`s not only for Twitter, today I saw it in settings when scrolled. I tried to record a video but on video there is no any difference I mean that it`s not visible on video.
[OnePlus 9 Pro] vincemue:
I would not use this ROM anymore, because it is not supported and maintained anymore.

thats why in my opinion it makes no sense to discuss any questions about things that do not work.
[OnePlus 9 Pro] Samuel Holland:
Thanks for the advice, I only mentioned, because I do not have these issues.
[OnePlus 9 Pro] TheGhost1951:
With this ROM, can we achieve full R/W capabilities on root partitions? I have the OnePlus 9 Pro running stock 11.2.9.9 with T-Mobile as carrier model LE2127.
[OnePlus 9 Pro] break.cold:
Your choice. I just do it fastboot flash boot name.img
[OnePlus 9 Pro] Evo609:
There were some errors on install, but it looks like it works now. Thanks, x100 :)
[OnePlus 9 Pro] break.cold:
Do one more time factory wipe from recovery before booting. It solve all the problem if you face in system
[OnePlus 9 Pro] Dharani_V:
Flashed Derpfest and booted into it. How do i flash magisk now ?

Nvm : found it . sideload magisk zip too.
[OnePlus 9 Pro] Ravel7774:
Will there be vanilla version?
[OnePlus 9 Pro] Leon2504:
I'm having Bluetooth connectivity issues when the screen is turned off, music stutters randomly until nothing comes through anymore, when I turn my screen on again it works perfectly without any issues.

Bluetooth device: OnePlus Buds Pro

OnePlus 9 Pro LE2123
[OnePlus 9 Pro] applyscience:
flashed this to my OP9(non pro) per @mattie_49 's rare praise. I came from cr droid and was rather happy with it, especially the optional gapps package to manage that aspect for losers like myself.

regaurdless, it would be nice to update to 12 finally but i am also very very lazy. thankfully crdroid also is a OOS 11 required ROM and both from from lineage roots so lets get DIRTY

i booted into twrp from fastboot (NOT flashed, just boot twrp.img if i ever want to use it, i just do that) the boot .img file. TWRP allowed me to specificy the boot parititon and on both sides. afte, factory reset and reboot to recovery. There, i adb sideloaded Derpfrost rebooted to recovery and applied magisk with sideload as well (zip isnt verified so get ready to confirm on your phone) (((if you have the apk. you have the zip. just rename .apk to .zip)))

and thats it. never had the problems mattie had re: 5G signal and verizon sim (dont have Verizon) but the bar is always max. could be UI, if so id feel really stupif for being impressed by it. ill test it later

TL:DR: was threatened to try this, fearing for my life, I dirty flashed from crdroid on OP9. it was possibly the smoothest dirty flash ive done (again thanks to lineage being a base for both). either way, im excited, thank you for this release. if you are every bored and dare to include a bild with GApps being optional

, I would consider licking your buitt.
[OnePlus 9 Pro] mattie_49:
Did you clean flash?. I've been on for a few weeks using with OnePlus watch and buds pro connected. I'm not experiencing this issue. My bt streaming music is good.
[OnePlus 9 Pro] mattie_49:
Twrp isn't compatible with A12 yet anyway. But yes I use Lineage 18.1 recovery img for everything
[OnePlus 9 Pro] Leon2504:
I know what the problem was, Audio modification library / JamesDSP / v4a, one of them was the problem, I don't now why but I can't use them without problems sadly..

I hope Dolby Atmos comes on derp asap and oos cam If possible
[OnePlus 9 Pro] mattie_49:
Yeah even though James dsp was recently updated it's still not compatible with A12.:( on A11 I was using the same bundle. James dsp allows viper's drivers to install properly. Then just use Viper.
[OnePlus 9 Pro] abduleo77:
Did you sideload magisk in the lineage recovery?
[OnePlus 9 Pro] abduleo77:
How do I flash magisk?
[OnePlus 9 Pro] theking37:
Yes I agree with applyscience's comment if the dev could add a vanilla build without gapps it with be greatly appreciated :)
[OnePlus 9 Pro] break.cold:
Flash Magisk through LOS recovery. adb sideload filename.zip

After successfully installing Magisk update to latest 24.1. You don't need boot.img just update the Magisk app and then direct install root.

I will provide you with Magisk.zip file in attachment. Update is your choice.
[OnePlus 9 Pro] break.cold:
Do the factory wipe after installing the rom. Just do the factory wipe and check again.

Personally, I bought OP9Pro for custom roms, kernels and root and roms experiment. I like Pixel 6 Pro but its expensive for me to buy. However, I ma huge fan Pixel camera, its one of the best camera. I used Pixel phone before, Google did excellent job with camera hardware and software/
[OnePlus 9 Pro] mattie_49:
I've been on the new builds over 2 weeks now. This issue has never come up.
[OnePlus 9 Pro] frost_icewind:
Alright, I've decided to try this out.

I've got a few questions...

Do I need to unlock my bootloader first?

I'm on OOS12. It sucks. I'll have to downgrade to 11 with local update first right?

Can I lock my bootloader again after installing this rom? Or can I keep it unlocked and still have L3?

Thanks in advance.
[OnePlus 9 Pro] abduleo77:
Thank you!
[OnePlus 9 Pro] golfgtiedition30:
Who cares , the rom's not been updated since April , move on.....
[OnePlus 9 Pro] TheGhost1951:
Any custom ROM with full R/W capabilities for the OnePlus 9 pro?
[OnePlus 9 Pro] Samuel Holland:
Hi, I haven't used this myself, but you can check this out if you haven't seen it already.

Using that on TMO stock 11, I was hoping that there would have been a custom ROM on A12 that was pre-rooted. Thanks for your reply!
[OnePlus 9 Pro] AlexeXt:
I am on last DerpFest and get this notification. I think it's from Google. How to disable this update?
[OnePlus 9 Pro] TheGhost1951:
Maybe go into settings then developer settings and disable auto updates...
[OnePlus 9 Pro] TheGhost1951:
Are the partitions in this ROM mounted as R/W?
[OnePlus 9 Pro] vincemue:
are you asking the same question every day?
[OnePlus 9 Pro] habobababo:
There is no android 12 with system r/w?
