Try the same as Mark Yngell Kate, the same ROM, maybe it works.

You are a god damn genius, thanks to you my sim is working now on rui2/rui3
But it's not working on crdroid v9.0 a13(will try other roms),

but the issue now is as soon as I turn off the wifi, signals are lost again, it's only working on wifi calling,
And the crdroid v9.0a13 doesn't support wifi calling so that might have been the reason.

Flash the latest stock update as a base, and then try the latest ROM on RMX6785 development, it picks up the better from the shared devices in same line of processor.

I, also, flashed, in order to fix some things, the ROM for Realme Narzo 20 Pro, notice that it has the same update for both https://www.realme.com/in/support/software-update but better search for newer updates than the official site offer for.

On it now, will also test out different situations,
Meanwhile @Mark Yngell Kate does your sim work with wifi off?

UPDATE:
can't flash custom rom because
after flashing RUI3.0 i am unable to boot into recovery mode neither stock nor custom recovery.
error = serial is not match fastboot unlock verify fail.
i can boot into stock recovery using fastboot cmd after booting into RUI3 but at that point custom recovery is replaced by stock one.
any suggestion??

I fixed all (download not complete, data partition corrupted, camera not working, Wi-Fi disconnecting randomly, baseband, and, I don't remember what more), less the IMEIs.

No, IMEI/s are not necessary to make calls, unless by some reason, some OEM, edit specific script or a specific app, to slave both, and this is not the case, I guess.
To make calls only, you need a baseband working. IMEI is used for other purpose/s, linked to personal finance security or anti-criminal measures, of course, without counting, politics for production handset line.

Using this tool https://mtktool.com/modemmeta-v10-2044-0-02 I had 99% of success, all the stages were fine, only the part of write IMEI, was not successful.

It could sound childish, but be sure your device can enter in meta mode, only using meta mode, the modem can be written, or at least, attempted to. Some builds allow sending device to meta mode, only using terminal through android itself, with reboot meta You have to check in device manager, which port number is updated, after to connect your device to PC.

IMEI, never, won't be recovered only by flashing an update nor upgrade, I mean, no firmware can recover the IMEI, only the baseband can be recovered this way, and then proceed by any other method to recover the IMEI.

Tried modem meta Today, successfully connected but same as you
imei download tool fails to even read the imei, let alone write,

However There is another tool in the drop-down menu, ("nvram editor") it is able to read the imei from device(target) db.
when I searched for "imei" it showed some folder named ""imei_svn"" something like that..
Under those there were file from imei(0)-imei(7) two more with value FF FF FF........FF i thik if we edit those and save that somehow it'll work..

I Tried to write it but the nvram seems to have no effect on it, like it's mounted as read only ..

then flash another rom

Here is a ss from same roms as you(nasustra v4.9 RUI1 as base) ,I also tried v4.1 v4.2 v5.1, crdroid lastest a13, RUI1 RUI2 RUI3....
The sim only works in RUI2 AND RUI3 that also only on wifi calling,
Can you check is there any file by the name of "sim_lock" in /nvdata/md>.

Can you also backup your nvdata folder from recovery and share it with me, i wonder what I am doing wrong..

Also did you flash your custom rom on RUI1 OR RUI2 as base??

ohky, thanks
i tried the same, looks like in India imei has been made mandatory to connect to sim network,
every time i insert a sim card notification panel says "sim 1/2 not allowed"..

anyways i suggest you edit your thread and put [SOLVED] in the title " https://xdaforums.com/t/realme-7-rmx2151-baseband-imei-null-camera-not-working.4493395/unread ".
and its >mount>nvdata, not "data" correct that also... details matter..

Hi,
Yes it works for realme C3,
Fastboot mode does not work well for these devices,
You have to use bootrom mode to flash twrp, stock rom.

I've tried it but still haven't installed recovery, I've done it with the sp flash tool, although if I've done it incorrectly I recommend that I do

The tittle in the thread is about IMEI lost and NVRAM issue related with. What do you want to do onto your device right now? Unlock it?, Which method are you using?

can you link that thread, i haven't found any thread with imei solution,
i did once used chameleon phone apk to write fake imei with root, but that fix did not work, (upon reset, imei was again gone)
also it only worked on low level androids, doesn't work android 11,12,13
