No SIM card detection after update firmware reboot in Archer MR600 v2
Hello, I bought TP-Link Archer MR 600 v2 last month in Germany. Today I was asked to update firmware, now I have this version 1.4.0 0.9.1 v0001.0 Build 210727 Rel.33453n.
After update rebooting, my device stopped recognize any SIM card, I tried to use on my smartphone and inserted another SIM card in device and nothing happened. I opened the settings website and still shows that SIM card is not connected or there is an error. I rebooted the system several times with different SIM cards (they are working properly in smartphone with perfect Internet connection) and nothing is happening. I saw in other forum about issues with this firmware version before and I really don't know what to do now. The device is completely new and was working perfectly. I'm afraid to update firmware version to 1.5, because is not from purchased area and I can loose the guarantee. Someone can please help me?
