Need help to go back to stock 11.0.2.2IN11AA

I'm not seeming to find coherent instructions to get back to stock 11.0.2.2IN11AA
I have the 8 Pro, rooted, newest magisk and I installed a magisk module that is now causing System UI crash at startup. I have tried a couple things: 1) tried the "adb wait-for-device shell magisk --remove-modules" --> nothing happens when starting back up except System UI error. 2) I've flashed back to stock boot.img (hoping to get to safe mode to disable magisk)...all I get is System UI error again.
So...what I want to do is start all over and end up with 11.0.2.2IN11AA rooted. Once I'm back to "factory" I'm pretty sure I can get back to magisk and root.
Can anyone help me with some decent instructions please?
Thanks

I can. So last week I managed go back from a rooted situation to stock rom with LOCKED bootloader. This means that you're phone will be as you bought it and you're gonna lose everything of course.
This video on YT helped me.

Yes, it's all true. Sorry for that i have now working for many days on this. Not sleeping enought. One more question that could bring me a step foward...
I was on IN11.0.2.2 before i locked the bootloader and bricked the device.
Now i downladed the Decrypted OxygenOS 11.0.0 IN21BA Version. I have now the error: Param Preload Device not match image. Question: Must i habe the Decrypted OxygenOS 11.0..2.2 IN21BA Version that it goes to work?
I can't the use the link for the right version, it is password protected.!
Thanks

The password is listed in the OP

Thank you, but I didn't find it.
One point I have forgotten to tell. Before the hard brick happened, I used Magistik and Patch a new boot.img then I flashed this with fastboot command. My failure was to make this 2. times. with different patches. The horrible thing is now that I must delete these files on my Laptop to get more space. When this the Problem of the MSMTOOL error is I had not really a chance to unbrick my device. Have anyone Downgrade with MSMTOOL the Stock Rom?
Thx for your help. I download now from OP the latest ROM. I will try it. I feel really scared. Maybe my device is not unbricked anymore.
The other Tool that I have (last chance) is the original Qualcomm flashing Tool QPST.

None of that matters.
1st identify your device!
What region is it?
If you have BA then don't flash AA you'll mess things up.
2nd visit the MSM thread!
Download the tool 'for your device!'
3rd boot to EDL (I responded to you in the romaur thread how to do this)
4th as soon as it's connected to your pc in edl, flash the device
5th MSM will relock your bootloader.
6th don't do something if you're not sure, just ask.
Oh and lol chill on the swearing also on posting everywhere, just make 1 thread and stick with it, people will help

Hey, my Phone is working like a charm. Thx for the great work !!!. I'm so happy !!!
It is better to come here to real developers, I had to get bad download links and bad Software! This was the only problem. For many years I have the first Samsung Galaxy and I'm knowing that I can get all the problems for not booting devices back. But I was scared that many Devices like Huwai bring their bootloaders with cryptographic methods in a safe trunk.
Best wishes to you, and the people that I'm working for the android project!
regardless,

[Solved] Stuck in Bootloader

so i was trying to flash CherishOS so i followed the instruction and found some problem but i was managed to solve the problem. FYI, the rom gave the link to the custom recovery which is the PixelExperience one, since i'm coming from the stock latest rom so i flashed that. until i done everything and boot to system, and it just keeps returned to the bootloader no matter which option i choose (boot to system & recovery), but luckily the device is still detected in my computer
What i've tried :
- flash recovery (PixelExperience & TWRP)
- Followed this instruction
but none of that is working, one thing i found out while doing the 2nd method is that it shows some errors like "flashing is not allowed for critical partition" and "partition not found".
I have no clue what to do, i've tried whatever solution i could find and none are working. please help, thanks
edit:
I also tried the "fastboot flashing unlock_critical" and tried to reboot into fastbootd but failed and the fastboot shows all command list

If i click on the link to download the recovery there is nothing about pixelexperience. So i guess you saw something about pixelexperience in the recovery itself. Thats not a problem anyway. You could use lineage recovery too. As long as the recovery is made for a12 thats not a problem as far as i know.
Its not written in the Cherish OS thread but in all other roms you have to be on the latest OOS11 on BOTH slots. Did you do this beforehand?
The easiest thing now is to use MSM Tool and go back to a locked oos phone.

yoo it works, thanks a lot man. hope you know how relieved i am
yeah i know it's not the problem, but it was the first time i know this recovery in like few years of modding my phone
also i finnaly able to flash the the custom rom, thanks!
I totally agree tho, the oos for me is the best stock rom, i tried the beta 1 tho, but it just leans towards to the color os since oppo is the parent company of oneplus. it just feels more heavy and too many change from the stock android. that's why i decided to flash custom rom
again, thank you so much! have a great day!

"Warning" Total Brick After Flashing Android 12 Beta

My phone is totally bricked, and it will not respond to anything, a totally black screen, after flashing Android 12 Beta using Fastboot.
I was on A12 Beta, I hated it, I wanted to flash AOSP, it did not work, so I decided to flash OOS 11 from Fastboot, it did not work either, I tried EDL MSM tool, it did not work either, it kept on booting into fastboot, fastboot loop, I extracted the payload.bin from A12 Beta using payload_dumper, I ran flash-all script, the phone successfully booted into fastboot the at the first section from the script, flashed the remaining files, when the phone attempted to rebooted for the final time after the script was completed successfully with no errors, the phone died at the final part of the script, which is the final boot, and it will not respond to anything, no sign of anything, complete black screen, I tried EDL mode, I tried everything, it's not responding to anything, I opened the phone and reseated the battery and the motherboard, still nothing. So Sad

Flashing roms via fastboot never works for me.
You should read the threads next time, there is no custom rom that works from a12, every rom need a11 as a base. And yes the a12 custom roms too.
Your only option is and was the MSM tool.
I was in a similar situation, i got my phone back with pressing vol +, vol - and power for i think several minutes while connected with a third party cable to my pc with msm tool where i already pressed start.
It started to flash everything somehow and i got a working phone.
Good luck.

A quick note: EDL mode will show nothing nor vibrate. The only way you know it's in EDL mode is that it's going to show up in MSM tool.
Just try using the MSM tool.
Start the program.
Hold the Vol Up and Vol Down at the same time for 5 seconds, then connect your phone to your PC.
If it doesn't show up in the MSM tool list, just hit Enum.
If you see the phone just click Start and wait for it to complete. For me it's usually around 300 sec.

Yes, OSS 11 is a must, I have tried downgrading and I guess "downgrading" is the issue here.
I have been using OnePlus since its first release, I am very familiar with it,
I have tried everything, but nothing works, I read more about this, and looks like the circuit is out of order, it will not pass anything "signal", especially to the screen.

Thats possible im not a pro. But from my understanding, its nearly impossible to brick a phone which is using a/b partitions via fastboot.
You tried a third party cable?

My last suggestion is to try to charge overnight and see if things are different tomorrow.
Other than that, only option is RMA as it's still under warranty.
Forgot that you already opened up the phone, so most likely they'll throw it back as it was opened by an unauthorized party.

OMG

Nobody believed me in the threads when this happened (end of Feb/early Mar). This wasn't spiteful in anyway either. It was more/less just unheard of and my methods and adherence to the most vital aspects for EDL recovery, were justifiably questioned. Unfortunately, in my case, I have had years of experience jacking-up my devices and I immediately knew/felt there was something different with this situation. In my situation though, when introducing how I had entered the predicament, it was strictly self-inflicted, complacency at its finest and terrible terrible timing for a well overdue slap-in-the-head to interject itself into my life. Did I mention I was OMW to Disney with m/wife, kids.....driving. I had 7 days to deal with at Disney with a pre-planned, fresh-flashed A-12 OP8....I ended up using my LG G3 which I had been spending significant time trying to develop into a dedicated full-fledged Kali device (had success w/that actually).
So seeing these posts and threads now is dis-heartening but vindicating. Had I not flashed A-12 the way I did, I would've been fine. I can not blame OnePlus for anything, I bought a locked-down (carrier unlocked) Note 10+ in its place and its driving me bonkers. I thought I would be able to tolerate the non-rootiness, but I've been flashing since my 1st smartphone, one of the 1st Galaxy's, the Verizon Fascinate.....good ol' Jelly Bean. Meanwhile, my lifeless OP8 sits on my desk upstairs surrounded by older devices.....its the only one that doesn't turn on.

Mar 3rd I posted for the 1st time about it.

That's so fed'ed up man, I am in the same boat as you, total loss, I am done with OnePlus, they can enjoy Oppo and ColorOS, A12 sucks and it's not for me.

Had to replace the motherboard (and flash the old persist partition to get the fingerprint sensor to work) due to this flash ddr mismatch crap. Shame on oneplus. They're being way too careless on this "unifying" trend.

OnePlus 8 Pro hard bricked

Hi, I was just wondering if anyone can help me. I know it's a lost cause at this point cuz it was my fault but I managed to get my phone to get bricked as I was trying to flash newer firmware for the phone. It succeeded without issues but when it rebooted it never wants to turn on. I've checked with an ampmeter and it's only drawing little power. It does try to boot but it thinks it doesn't have any firmware on it if that makes sense. I can't get it to EDL or even diagnostic mode.
Note:
Running Pixel Experience 12
Android 11 firmware (Tried to update to 12 for 5g modem)
Any sort of help or info would be appreciated cuz I'm pretty devastated from my mistake
Thank you
Note: I've realised that the video didn't load so here is the link of my trying to power it on to EDL Mode

I was flashing the firmware that was from the official OTA firmware and it just decide to crap itself. I have assumed and probably will think that the device is fried cuz of the memory confusion.

Its not a problem if you flash it as local upgrade inside OOS but it can be a problem if you flash it via fastboot

Were you able to fix this somehow?

hello, did you solve your problem? Or did you change your motherboard? I'm having the same problem right now and I don't know what to do

Had my motherboard replaced by OnePlus service.

hello, is your device working now? How much did the service charge?

Hi, I was just wondering if anyone can help me. I know it's a lost cause at this point cuz it was my fault but I managed to get my phone to get bricked as I was trying to flash newer firmware for the phone. It succeeded without issues but when it rebooted it never wants to turn on. I've checked with an ampmeter and it's only drawing little power. It does try to boot but it thinks it doesn't have any firmware on it if that makes sense. I can't get it to EDL or even diagnostic mode.
Note:
Running Pixel Experience 12
Android 11 firmware (Tried to update to 12 for 5g modem)
Any sort of help or info would be appreciated cuz I'm pretty devastated from my mistake
Thank you
Note: I've realised that the video didn't load so here is the link of my trying to power it on to EDL Mode

Bro just use msm tool that will fix it anyways

I did a big dumb. Failed root

Howdy. Tried to root my OnePlus 8 Pro. First time trying such a thing... Having now bricked my phone into a boot loop, I'm pretty sure that the guide I followed missed an important step. It said to download the latest patch, extract it, then use magisk to patch it and flash it. I'm pretty sure that the part I missed was actually updating to that patch before flashing. So I have whatever latest patch that I didn't have the foresight to write down, but my original build was IN2025_11_C.33 . Am I boned completely and thoroughly or is there any hope of recovering? Thanks either way.

LOL, welcome. Wisely, you've chosen a phone that supports EDL, with known ROMs. EDL will allow you to reflash to factory, no matter how badly you've messed up, assuming you didn't brick the hardware (which, unfortunately, is actually possible with this phone- there's two different RAM voltages and you can flash something that writes the wrong one and literally fry the phone... sigh)
All the stuff you need is covered in other threads here, and in other OnePlus forums on XDA... too tired to summarize them all (sorry). Search for the MSM tool (I think the one you want is here but please double check) and how to use it. Happy flashing, and welcome to the best phone mfr to mod! (Note EDL requires a Qualcomm chipset, there are other OP phones that do NOT have them... so not EVERY phone is bailable-outable...)

In case you haven't sorted it yet - this is a great MSM guide which also links to the Windows drivers you need and the MSM tools for your device.
Good luck
