Hello, same issue for me, same model Redmi Note 12 Turbo China model, I am currently running MIUITN v2.2 which doesn't have this network issue.

Hi,
I also confirm this post, i'm using an AOSP based rom (evolution x) and i have no signal issues, 3G/4G both work and no dropped calls, MIUI EU is always having dropped calls and no signal
Hi,
I also confirm this post, i'm using an MIUITN 2.2 rom and i have no signal issues, 3G/4G both work and no dropped calls, MIUI EU is always having dropped calls and no signal.
So that there is no network crash in the xiaomi.eu rom, the following parameters must be adjusted:
1. Change model and code device from CN version:
odm/etc/marble_build.prop
vendor/marble_build.prop
2. Disable in vendor/build.prop:
persist.vendor.radio.dynamic_sar=0
persist.vendor.radio.apm_sim_not_pwdn=0
3. Disable ramdump in system/build.prop:
persist.mtb.modemdump=false
persist.vendor.ssr.enable_ramdumps=0
4. Change in system_ext/etc/build.prop:
ro.telephony.sim_slots.count=2

I find it funny that you simply change props arbitrarily without trying to understand why you even need to change them.
None of these props, besides the model props, are being touched by us, nor do we change the modem firmware.
So, what makes the difference with China ROM - that is the question.
Good question !
But first tests on 4pda from Kosmosik96's modded Xiaomi.eu latest rom seems to confirm it works...
Did not try it yet myself. (still on MiuiTN)
We are trying to solve the problem and test any possible solution, if you have other solution we would love to hear about it.
The network problem is real! and it makes is almost impossible to use the phone... so we are trying to solve it by any way possible, without having to wipe all the data and use other rom!
As for the props changes in other forum they said that this solved the problem so we try it too, the reasoning behind this is the following as explained is different forum:
"most likely the firmware reads the device model from the vendor and, depending on this, uses different settings for the modem, by default the drops were
constant, after I returned the model to the vendor the dumps became rare, then I changed a few more lines in build.prop and the dumps have completely stopped, I already described in more detail here"
If you can contradict this or approve it we will appreciate it.
Again if you have other solution please share with us, if further logs or other data are required we will happy to supply them, just say what is needed.
Thanks!

By modifying these props, you stray away from China ROM even further, but go ahead, I have other issues to tend to.
Again if you have other solution we would love to hear about it.
Can you help us solve this issue? Do you have any ideas? You are the expert here, if any data is needed please let us know we will supply it.
Please help us solve this.
Thanks,

hope a solution comes soon. For now using the device in 3G only mode seems to be a workaround.

the prop settings dont work for me, only improve a little bitThere is already a solution, see the link above.
I'm not sure how to do this, does it need root?

Hi, May I ask a question regarding EU ROM based on china's ROM ?
Currently on MiuiTN ROM, I can catch some apps trying to contact chinese IPs (app : com.xiaomi.xmsf ; same for com.xiaomi.bluetooth), I also must insert a SIM card to be able to activate USB debugging, network must be ON and unrestricted when I want to give an application permissions to install apps...
You can't enable Unknown Sources without creating a Xiaomi account...
How it is handled with Xiaomi.EU ROM ? Does the same happens ?
Thank you.

What this have to do with the thread though?
And no. Dunno about the Chinese IPs, some of them are related to MIUI online services.
You are a kind of magician
Why don't you want to help us solve it?
tell us what is needed to solve it?
Thanks,
You are right it does not solve the problem... i still have drops.
Did you try the firmware they sent?
