Question Does anyone have a fix for the SIM not being detected on A12 Custom Roms with a T-Mobile convert? - OnePlus 9

Technically the sim sometimes gets detected if I keep restarting the phone but after having to restart it 13 times earlier today to get the sim to work i decided it wasn't worth. I saw the fix for OOS12 but I wanted to know if anyone knows of a way to fix it for AOSP based roms?

[Q] Changes to PRL/NAM reseting

Hello all,
So I just got a Verizon Razr HD xt926 and while trying to flash the phone I am having a problem getting my changes to stick. Everything appears to work fine, boot up using BP Tools, install drivers, connect to phone, make changes, write changes, restart.
Upon restart all my changes are lost. Anyone else having this issue?
This phone was unfortunately updated to latest OTA so bootloader is locked, but I didn't think this would cause it to not take a updated PRL.. anyone else having an issue? Any ideas or suggestions?
TIA
Seriously I am the only one with this problem?
Well so far what I have figured out is it has something to do with the newer Verizon SIM cards, they are what I'm calling "PRL Locked" ...
With no SIM in the phone I can write changes using QPST and do not get a SPC_CHANGE error
However put a brand new SIM from the Verizon store in the phone and it's locked to PRL 15009 and none of my NAM or PRL changes stick...
Waiting for a older Verizon SIM card to arrive to test and see if it makes a difference or not.

[Q] [HELP] CM10.1 on K860 problems

Hi there
Im having trouble to get CM.10.1 working on k860. What happened is i downloaded the latest cm10.1 szb file and placed it in sdfuse after backing up all my files etc. Then when i flashed the rom- The phone allows me to use it without network coverage for a minute or two, then locks it. SIM lock- and my sim code does not work to unlock it.
The Overseas firmware rom works perfectly, and enables me to do all the things.. however, i want to switch to CM. i dont want to keep using it.
I tried to install the CM10 some time ago and I had the same problem, I thought it was a baseband problem that was related to CM programming. I cant find any details on how to unlock my phone. I dont think its locked onto the carrier because the first sim i used was a chinese sim bought in beijing.
Help.

[Q] Dual SIM ROM in Single SIM Phone?/ SIM Not recognized

So Ive been trying this for such a long time its disgusting. The thread title is my own conclusion from my research throughout the web but I may be wrong in my conclusions.
I have a Huawei G510 since last year. As soon as I got it I rooted it and found a ROM for it. The ROM is a dual SIM ROM and I remember doing something related to a cust folder or something, but I'm not sure. Fast forward to the last few weeks, I want to update to 4.4, and I download a bunch of roms, all of them work except for 1 thing: They dont recognize my SIM Card. I go to Status in the settings and everything about the SIM is "Unknown".
I found a Lewa ROM based on JB and that one was by chance a dual SIM ROM, and guess what, its the only ROM that works. So thats how I concluded that installing a dual SIM Rom must have changed something so that it doesnt recognize my SIM anymore?
So what should I do? Thanks in advance!:good:
anyone? any help is appreciated

Sim card issues on anything other than Android 11

I've been running the official release of Android 11 on my Pixel 3 XL without issue other than I'd like the battery life to be a little better. Had a really weird issue that maybe someone might have some insight about. My sim card only works on Android 11. If I run the official Android 10 from August, no sim detected unless i take it out and put it back in. I select the apn and I don't connect. Upon reboot the sim is not found until I take it out and put it back in. I tried Havoc GSI (10) and PixelDust (10) custom roms and don't connect with them either. Used the Android flash tool back to 11 and sim works without issue.
Figured it out. If I unlock the bootloader, the sim doesn't work. Never seen this before on a phone.

Question LE2117 Tmobile variant issue.

So I have lineageOS 19.1 (android 12) on my tmobile variant oneplus 9. It was a long bloody war and much sleep was lost along the way. Everything seems to work okay, kind of. Phone gets stuck in fastboot for 2/3 times every time I restart it. And I have no data or sim card even detected when it does boot. I think it all comes down to the modem.img. I assume that I just need a modem.img from a stock android 12 tmobile variant, so if anyone could supply me with one of those (I have searched and haven't found one anywhere) I would be quite thankful.
Or if you know something I don't and that's not even the problem, please let me know.
