Question Xiaomi 12T Pro Firmware/modem failure! (Trouble with storage and eSIM)

[gs_Grey]

Hi there!

I Have trouble with my Xiaomi 12T Pro. Firmware modem failure, when eSIM is enabled. Modem failure causes a lot of ramdumps to /data/vendor/ramdump/ And it fills up the storage.

Bootloader is unlocked, have root and TWRP. I installed the latest firmware modem from Xiaomi - this did not solve the problem.

Ramdump attached.

Help please!
Sorry for my bad English


There is two problem:
1. Spontaneously fills the memory in the phone until 0 KB remains. After the phone reboots into recovery mode and does not turn on until the Data section is cleared. After turning on the phone, the problem recurs, but not everytime.
Looks like, Filling of storage is stopping when the eSIM is off. I suspect that the problem is somehow related to eSIM, since there are also big problems with eSIM.

2. The eSIM profiles of AirAlo is working good. But the eSIM profile of a certain operator is not working in Ireland in the same time. Despite the fact that the physical sim of the same operator works fine. That eSIM was working good in in Latvia and Lithuania before, but not in Ireland in my phone. Also that eSIM profile is working good in iPhone (iPhone is not my)

When I install that profile, all networks in the phone is lost completely (and the physical sim stops working as well). The operator checked everything and excludes errors on his part. Screenshots are attachment

Are you sure of the letters, because RU corresponds to Russia and no Russian version for this phone?
Is this a 22081212C version?

Yes, I am sure

Yes, I am sure

It looks like the K50 is C and the 12t pro UG
indeed there are Russian roms and you are on the latest version.
Try to do a factory reset.

I am sorry to tell you because i have been in the some problem and you have two options,
you can see on the mi website:
"Dual SIM (nano SIM + eSIM and nano SIM + nano SIM)*Use of eSIM requires a wireless service plan. This service plan may be subject to certain restrictions of use on switching service providers and roaming (even after contract expiration). eSIM availability may vary depending on country/region and carrier (https://www.mi.com/global/support/esim). For more details, please contact your carrier for more information. "
