Tried Flashing Lineage OS, now my cell signal doesn't work

Based on the comments I wasn't alone in this issue but I haven't seen a fix. I even went so far as to use the MSM tool to no avail. Any suggestions on how I can get this thing back to life?
Flash lineage over 10.0.3 oos. Or one of the betas. It's weird it's like after I msm tool back to 9.5.3 I don't have or won't have cell service until I updated regular way to 10.0.3. and regular way I mean by system - system update. Or do the load local in system update

Ok when you say custom kernell are you meaning like the Smurf kernel, ummm sky dragon in that sort. I haven't really had a chance to ask til now. Why I ask is for 2 reasons I have read where some call a partition a kernel. And when I first got my 7 pro last yr right before the q beta came. Tmo I was doing the international msm tool but I found away and til this day I can msm tool my other 7 pro with 9.5.3 and it will keep the network everything. But now I can not find the xda forum I read it at. And can't member what I did to make it stick like that. Our 7 pro forum has came along way.

Yeah a custom kernel. The kernel will have its own partition jus like system ,data, modem, etc,etc, they are all partitions of the device. It would be more like kernel partition system partition data partition. You'd jus leave out the partition part so you didn't have to say 10 times

Question [HELP]Fat fingered OOS12 OTA update on rooted stock OOS11 and now I have no touch input.

Hello all,
I ****ed up, what I feel is big time?
I accidentally fat fingered the "install and restart" button for an OTA update for OOS12 on my rooted stock OOS11. From what I learned during my research phase of rooting my OP9, that's a big no no and can cause a lot of problems. When the phone booted back up I have no touch input at all. I have a mouse plugged into my phone and can use the phone that way and I am currently backing up as much as I can in the event I have to wipe my phone.
My question is, can I just dirty flash the previous OOS11 image I was running to go back to before the OOS12 OTA got applied? Just wanted to get the general consensus before I ruin my **** further.
I'm running stock recovery, stock OOS11.2.4.4 with Magisk, MagiskHide and not much else.
Much appreciated!
To my what i know you have to downgrade from 12 to 11 ect. I managed to get to global.
I messed up, and updated mine to 12. and from what i learned. my touch screen did not work due to the fact my update was for a global 9 pro, Not my oneplus 9-tmobile version. In the end I had to use the india msm tool to get back to working

I would def recommend just MSM back to stock 11.2.4.4, I was in your same situation before and I always had the touchscreen issues if I was rooted when I upgraded to OOS12. I think I tried flashing back to 11 and just ended up soft bricking my device and having to MSM anyway. Also like the commenter said above I had to use the Indian MSM but Ive been able to use the Global MSM now with no issues so if thats what your're on Id recommend trying that one first and only using the Indian MSM if that one gives you errors.
So I'm running into this same problem and absolutely can not upgrade to OOS12. Each time, by display will not respond to touch. I went back to 11 via MSM (HAD TO USE OP9 Pro INDIA) because OP screwed something up with these phones.
I have tried multiple ways, went back to OOS 11, installed latest OOS 11 without root. Locked bootloader, Installed latest OOS 11 twice via system update to make sure everything was clean. Installed OOS 12 update and same problem.
Same problem here.....
I have installed the msm india and then the official android 11 for OP 9. After that the OP9 runs on Android 11. After that i have closed the bootloader and try the msm with the eu rom and i gets the "device not match image" error. Maybe i have the new rom for op9 installed and the productnumber is still on op9p ? Now i am going back to a custom rom. is there an option to get the fully working camera on a custom rom?

To get back to the correct ROM, boot to TWRP and flash the signed full zip to each slot.

Reverted from COS12 fingerprint/ face unlock bug

Recently reverted from ColorOs12 build to original Oxygenos 10. Had the auto rotate bug, fixed it. Now fingerprint, face unlock, and ambient gestures are broken. Anyone have suggestions on getting back to fully stock? Already tried MSM tool with no luck.
Edited. The file and advice I was giving was a last resort before sending back to OnePlus. Follow advice below and if you need persist.img as a last resort I can give you the link later.
Never use someone else's persist file. I went back to oxygenOS 9 by MSM tool then upgraded via ota to 11 then i download my persist file by MSM tool and edit it in Hex-master. You have tutorial on techibee channel on YT.
After that rotation works good but i dont have fingerprint too. I download this version of oxygen os11 what i actualy have by oxygen updater and flash it by localupdate in settings after that all works like before flash colorOS 12

Oneplus 8T problem with update android 12

Hello all.
Today my phone Oneplus 8T just informed me that I had my android 12 installed and I just have to restart it.
I don't want that Android 12 by Oneplus, it is ****.
Now this thing lags, just 15 minutes ago my phone did not lag...
My phone is completely stock, what custom ROM I can install so I can return to stock android without bull****.
Help me, please!
I can't stand that ****!
Thank you!
Just use the rollback package to go back to oos11. Look at OnePlus forums page for Android 12 update for 8T. The rollback package is in the first post.
You'll find the rollback packages here: https://forums.oneplus.com/threads/oxygenos-12-for-the-oneplus-8t.1555060/
Well I got angry and deleted the os and recovery somehow with my custrom rom attempts to install.
Now the device can only boot into fastboot mode and can't upload to the phone any custom recovery so I can fix my phone.
[SOLVED]
Special Thanks to:
TuDi
Andri
On Telegram group for NamalessROM
Without them, especially TuDi I would not have powered my device today!
I had to MsnDownloadTool to stock android 11 and then flash recovery , partitions and Rom.
And I have to say I absolutely love this CustomRom.

after android 12 update screen keeps flashing

Hi, I'm hoping that someone can help me.
after installing oos12 on my oneplus 7 pro my screen started to randomly flash.
i cant find anyone else that has this issue anywhere else on google.
Attached video's are from the CrDroid rom but the same thing happens when I was with the OTA oos12update
so far I tried to:
oos12 firmware via the crDroid page here on xda.
when I download the OTA update from oneplus themself (after the msm reflash) the blinking returns.
oos12 and oos13 rom from crDroid (including their recovery firmware)
evolution Rom (including their recovery firmware)
back to oos11 via the msm tool. this fixes the flashing issue, but i prefer not to stay on oos11 when I can run new roms).
does anyone have an idea what could fix it, I'm willing to try just about anything.
i think go back to OOS11 might help
