RUT 951 update to RUT9M_R_00.07.12 broke SIM detection

Hi
I faced on thursday a big issue :
I have a fleet of dozen of Teltonika routers both RUT 950 and 951. We made an global update of the firmware on all of them.

But on 3 of them, we had replace them physically on our products because they were no more able to connect.
Obviously we kept configuration after upgrade and did not change anything. THe SIMs are comming from the same batch and provider with the same config, etc …

The 3 faulty RUT 951 are of the SN serie : 11263xxxx
Their HW revision are 2020, the OK ones are HW revision 0202 or 0303.

Common information (faulty or not) :
WEBUI = RUT9M_R_00.07.12
MODEM FW = SLM750-V_4.0.12_EQ101 so ON MODEM is SLM750-VE
(nota, no issue with version embedding Quectel MODEM)
Bootloaders are most of the time 4.0.8.

Anyone experienced the same issue with HW rev 2020 (surprisingly near the 0202) ?
It really seems related to an incompatibility between HW rev 2020 and this FW version.
Also I notice that on this HW 2020, an eSIM menu appeared.
Attached some screenshoots.

What I also observe is that the SIM card, once inserted in any slot, is orange with the message not activated.

I tried to downgrade to RUT9M_R_00.07.11.3_WEBUI.bin that previousy worked without any success.
Please help !

Kind regards
Vincent



Hello
Additionnal information, after factory reset without any SIM inserted + new update to RUTM9M_R__00.07.12, I have an SOM3 (eSIM1) that appeared !) :slight_smile:
But related to other topics in this forum, eSIMs are normally not already supported :slight_smile:

Thanks and BR
Nota : Tried to downgrade to 11.3 then 10.2 (original one) … not better , SIM not detected. SIM working in other routers, and used to work before V12 upgrade.
