Noob alert: broken dual sim functionality

Hello, thanks to my carelessness, I think I broke my dual sim functionality.
What I was doing was messing around in the network settings in Engineer mode that can be accessed using *#36446337#. And all of a sudden, both sims stopped working. After a lot of messing around with the RAT settings, I could get one of the sims working. After selection sim1 or sim2 in the options and changing the RAT settings for that sim, I can get said sim to work, but it breaks the other. No matter what I do, I can't get both working again. This was on Open Beta 9.
What I've tried doing since then:
1- Factory reset
2- Flashing another ROM (Lineage)
3- Flashing latest 4.0.4 firmware
nothing seems to get both sims to work. Always just 1 sim working. Does anyone have any thoughts what I could try?

Just do a full wipe with the unbrick tool and everything will be back to normal.

I have the same problem after I mess with the engineer mode.
Tried everything and still unsolved.

Try installing the modem or firmware of previous oxygen OS builds then updating the oxygen os

Yes, I tried the unbrick tool but it's still the same. It seems to me that the GSM/WCDMA band of the phone is broken. When put two LTE card into the phone, both can work under LTE band.

Installed the OOS3.0 and then updated to OOS4.0. Dual sim function won't work on both OS.
Flashing modem usually can solve signal lost on Samsung, but it seems that it won't work on Oneplus.

Well you just said you are a noob.. No problem but really dialing a number isn't going to break anything in your phone.. Wipe all partitions then Flash OOS 4.0.2 and o guarantee it will work, this is pure something in software level.

I have successfully fix the problem according to a post at Oneplus Community in China. Just Flash Official H2OS 2.5 (Android 6.0.1 ). Go to engineer mode. Choose Network Set -- Band mode --Hardware Default (Foreign) to fix the problem.
P.S. If you are in mainland China. Pls choose Hardware Default(China). Else choose (Foreign)

SIM card autodetect

Hi, I have installed Pie update on my Mi A2 Lite however due to amount of the bugs I got back to Oreo V9.6.10.0.ODLMIFF. Since that time my SIM cards got swapped - SIM tray 1 is visible in settings as SIM 2 and vice versa. What is more annoying whenever I insert new card while phone is on, it does not auto detect that SIM has been just inserted and need to reboot phone each time I replace SIM in order to get connected to network. Can anyone help me with fixing this so the SIM ordering is corrected in software and auto detection is back on? Already tried reflashing rom and getting back to Pie but no improvements.

Hi,

Wrong encryption PIN after downgrading LineageOS

Hi!
I updated my LineageOS to the latest version on my Pocophone F1 and in some reason my other SIM card stopped working. Therefore did a downgrade back to the previous version but after that could not access my encrypted data - both TWRP and the system (during startup) are saying "Wrong PIN".
The only thing I care is how to get back my data. Please does anyone know how to do it and why has the encryption key changed? Thank you!
Best Regards,
johann3z

Custom Rom with disable 2th sim card from software?

Hello! Can you recommend a custom rom for Oneplus 3 that allows me to disable the second sim directly from the software? I tried Lineage OS and Pixel experience but they do not allow disabling the sim card. It must be completely removed from the phone if I want to deactivate it. Thanks!

I'd like to second this - I rolled back to Lineage 16 because of this very issue - one SIM.is mine, the other is for work. It was either carry two phones or roll back. Is there a custom ROM out there with this option?

Question No Network Connection (RIL Dead)

Hello everyone. I have a realme GT Master Edition (RMX3360).
The problem I am facing is that, SIM network does not work. SIM is recognised but it won't connect to any network, so basically I cannot use the SIM card even though the phone knows what SIM is this.
I did try:
Factory reset.
Use Force LTE app to access phone information and switch bands (I noticed radio toggle is switched off, I tried turning it on but it won't).
Unlock bootloader, just to increase my chances.
Flash only modem/hlos/... related partitions. Did not work (phone bricked).
Flash OFP firmware. Did not work.
Flash EDL firmware (C.09), which I am currently using. Still same problem.
Different SIM cards.
My IMEI is fine, it is recognised. My baseband version is 4. I did search for the issue in realme community, and it seems quite popular as a lot of people suffer from the same issue on different models.
I live in Sudan, we got no 5G, no VoLTE or whatever. Could you help me please?

I have similar problem after reboot .I can't connect to network or it tooks long time . What helps me is switching to airplane mode.

Switch to global rom maybe your sim card provider not supported switch to Rx3363

Thanks for the suggestion. I did install RMX3363 EU ROM from EDL, it booted fine but the phone still won't connect to any SIM network.
I will also try Russia ROM to see if it would make any difference.
Update:
I did flash Russian ROM from EDL, still does not work. Modem version is also still 4. I will try Chinese ROM next.

Try Latam version this what they put in middle east but so far i think its hardware issue did u try the sim card on another phone? Did you try another sim provider on your phone ? Sometimes if the sim card too old it wont work

That LATAM version is 18 Gigabytes haha. It'd take a few days to download.
I came to think it might be related to modem images as it showed the same version repeatedly on both RUI 2 & 3. So I'll try different modem images.
Also I'll try custom ROMs and GSIs. If it failed I'll return the device as a very last resort.
Update:
I tried latest Official ProjectElixir till date, still same problem.
Update 2:
I gave up the device and replaced it with another one under warranty. I will not buy another realme phone anytime soon.

I have a Xiaomi device too. The new virtual proximity sensor depends on hand movement to function. I don't use MIUI, but it is very fine at all situations.
Also I got a (256/8) GT Master replacement which is surprisingly working fine; being the same RMX3360.

It was already updated to F.03, I heard there was screen flickering or something but I didn't notice any so far.
But I did notice the battery was draining fast on mobile data. Really fast.
Besides, I can always lean on post-market development.

The general feel of the update is slower than the android 12 version
The battery will get better with you try to froze the app you dont use
