Empty or 00000 imei happened on custom rom ?

[starvirus10]

Hello, I'm from Indonesia

Here I found a bug on my device (Sony Xperia xz1 (G8341)). The bug is a little strange
Because it happens in a certain simcard I hope there will be a solution but maybe now I can only hope.

I use two simcards in turn. Simcard A runs normally, there are no problems, but once I switch to Simcard B, there are problems such as being unable to make calls, sending messages and cannot connect with Internet Though the internet is the most important

I did a trial by changing custom ROM starting from LineargeOS 17.1, CarbonOS, LineargeOS 16 and a few more. but the problem persists and in the same thing too

I try to go back to Stock SOV36 (9.0 Pie tail s126) Sony Xperia xz1 (single) .
sure enough the simcard that had problems returned to normal

I use Custom Rom again and yes the problem arises again and again

I checked * # * # 4636 # * # * it turns out the missing IMEI changed 000000 I tried another Simcard IMEI appeared I tried another IMEI Simcard to appear again

BUG only occurs in special simcards that only receive signals 4G Only and use the CAT40 frequency and for other simcards that can accept all types of 4G, 3G and 2G frequencies there is no problem.

For me and some friends who have experienced this problem on the Sony Xperia xz1 (G8341) and the Sony xperia xz1 series. can only wait for the resolution of this problem For me and some friends who have experienced this problem on the Sony Xperia xz1 (G8341) and the Sony xperia xz1 series. can only wait for the resolution of this problem

May the storm pass quickly Sorry to talk too much : D
And sorry again I'm bad in English

@starvirus10, that's interesting. Is the phone the SOV36 model?
If so, it is obvious that running fw built for different yoshino model could cause problems.
I wonder - did your SOV36 come with unlockable bootloader?
Just asking because they are folks with SOV36 that are not allowed to do BL unlock.

I think so, but when I bought this Smartphone the software used a Global version . I just recently changed to SOV36

hmmm ... Bootloader Status: yes when I check open No like most bootloader defaults in stock ROM

About Some Simcards detected Null / 000000 I tried to flash Sony_diag.zip to fix the baseband and it worked. if there is an opportunity maybe I will post it
to help others if you have the same difficulty

Interesting. I do not have this problem, but you seem to be already a second guy who encountered loss of imei:
https://forum.xda-developers.com/showpost.php?p=81898823&postcount=23

Yes. It doesn't show an imei. And no mac address too. I'm surprised downgrading, and upgrading OS doesn't fix it. Xperia companion app repaired phone successfully but still no imei or WiFi mac.

Kindly check attached picture. I got that screen via a USSD code I got through Google. It shows there's an imei somewhere.

What do you think coukd help restore imei?

I need diag mode to rewrite thesame imei.

Imei tool can't currently detect phone

So it may actually be useful to post something to do imei recovery.

Sometimes when doing a custom flash. Some things might disappear and make the phone not work properly. I myself made a headache because of that ?

Actually, to improve diag in the forum there has been discussion. we just need to search with the right keywords

@starvirus10, accessing diag port is one thing, not that interesting.
but how is the imei recovery done via the diag port then?
