I have been porting MIUIv4 for Xperia J and after I installed 99% working build my phone stopped recognizig SIM cards.
I have restored CM10 backup, flashed stock ics 7.5, OTA updated to JB, flashed again with SEUS but nothing helped. I treid flashing it without pressed sim and with sim inside. No result.
My phone doesn't recognize any SIM card, it says on lockscreen "Invalid sim card". Please help me
it seems like SIM lock but I have never had it ;/
So I finally got around to rooting my phone to get rid of bloatware. I deleted something I shouldn't have, though, because I got stuck in the LG Security Error boot loop. Sooo, I reinstalled stock firmware, but now my SIM card won't read. Any ideas of what could be causing this?
I realize I should have unlocked the bootloader but, well, oops.
I ended up reinstalling the stock firmware using the LGNPST setup. I tried two separate files, the .tot's for ICS and JB, but the problem persisted.
My phone still knows it's IMEI # and although I've tried multiple SIM cards, my phone couldn't read any of them. I have a SIM card that wasn't working in my E970 in my backup phone and it's connecting to the network just fine.
I downloaded a SIM utility from the Android market, and even if I insert a SIM card, the utility just says that the card is "Absent".

I own a Lg G3 sprint ls990.I live in Bangladesh.My device was on android lollipop and it was fine.But due to restart and warming issues i flashed into stock kitkat rom using flashtool.After 91% of flashing a red screen poped up in my device it said "warning; not support qem=0" and in the flashtool app it said failed.But when I pulled out the battery and rebooted my device I saw everything is okay.Then I put on a working sim card and it couldn't detect the sim card.i tried with whole other working sim card but i couldn't detect.I changed my sim slot but that also cannot change the condition.I flashed with other roms but still nothing is happening.When i dial "*#06#" to know my imei it says "connection problem or invalid mmi code".......Now Im badly in need of your help guys.Please,do help guys.
A really weird problem appeared on my device after upgrading to the latest miui 8.7.19 global beta from the 8.7.12.
After this update my secondary SIM slot stopped working. It reads the SIM correctly but it can't connect to the network.
If I put the same SIM on the slot1 it works, if I put it on the slot2 it doesn't work.
It's driving me crazy because I have the need for 2 SIM for work.
I already tried to revert it back to the old ROM via fastboot formatting the phone but it did not help. The problem is still there.
Can someone please help me? thanks.

I have the poco x3 pro, I did have the infinite boot loop issue, but by pressing the power button 10 to 12 times quick this got fixed, however I now find myself stuck on the enter pin screen for my sim card. I try to enter the pin, but nothing comes up on the screen.
anyone got any ideas of how to fix this ?

Put the sim card into another phone, type in your PIN, remove the PIN from the sim card, put it back into your phone and it will boot straight into Android

I Did that, seemed to work, but then locked up again. I Think it only happens When sim cards are inserted

Can you try someone else's sim card in your phone? Maybe your sim card has a problem and needs replacing.
Also, maybe it's ROM related. Try finding out whether people running the same ROM have similar problems
I Cant even get the phone to boot properly with or without sim. It just freezes after booting. I fear its now had it.
