My phone shows an exclamation mark "!" on the sim card signal icon. I tried searching a lot through internet on solving this issue and I couldn't find anything that helps me to solve this problem. I tried rooting the phone and I actually failed to and since then I can use it in making calls or sending messages but everything else is working just fine.
Btw am using a xperia Z5 dual sim.
The bootloader is unlocked if that makes a difference.
Android version 6.0.1
& also I can't enter recovery mode.
Tried to turn the Radio ON in the *#*#4636#*#* , didn't do anything, won't turn ON.
doing a factory reset did not work.

I just got this phone brand new a couple of days ago(P769 model). Everything seems to be working fine, except that sometimes when I try to send a text over wifi calling, I get an error message that says "No usim card". So far resetting the phone each time I get the message has fixed the problem and allowed me to text, but it seems like the type of thing that will only get worse and more frequent as time goes by on top of it being mildly annoying having to reset my phone every time this happens. Any ideas on how to fix? I tried swapping out my old sim card for a new one, but that didn't help.
Never heard about such error. USIM is simpy a SIM card supporting UMTS with no software emulation. Try emergency firmware recovery from LG PC Suite. It will wipe all your data so make a backup if needed.

Do I need to download a specific version of LG PC Suite for the 769. I couldn't find a link to it on LG's website. I tried downloading the version they had linked to the 765, but my phone would never connect with it. It would say it was connecting for about 30 seconds, and then it would say it failed.
You can use this method: http://forum.xda-developers.com/showthread.php?t=2085344&highlight=lgmobile+support+tool
Or just download LGMobile Support Tool (p. 3 in above post), install msxml.msi than B2CAppSetup.exe, run it and connect the phone, upgrade recovery from options. I was recovering my phone this way after failed rooting of the device. BTW PC Suite should work with all p76x.
Hi
I believe that my phones radio capabilities may be disabled. I tried to root my phone but ended up flashing it with an ftf file and now i cant connect to my mobile network with my phone, Ive tried multiple simcards and flashing my phone a few times with different ftf files.
Everything else on my phone seems to be working fine except ability to connect to mobile network carrier.
I cant unlock the bootloader or use s1tools because it cant recognise the certificate or something like that, I can flash and root the phone though.
can i save my phone and how?
Hi
Today i flashed and rooted my unlocked xperia x10i with flashtool and the provided .ftf file, "X10_V1_BLRelock.ftf". Pretty much after that my phone had been reset and i couldn't connect to my mobile network.
During the initial setup after the flash, my phone asked me to "Please insert sim card and restart your phone", Now in the drop down bar is has a "No service, selecting network (yes optus) is unavailable). Originally with this phone and my x10a the other networks had a red circle indicating i couldn't access them however right now i can try to connect to all of them but fail. everytime i try to connect i get the message "Your simcard does not allow connection to this network". My APN list is blank but it has always been blank.
My simcard works in another phone, other simcards dont work in my phone. I tried flashing my phone again and rooting it again, with multiple ftf files. I was going to try installing another rom for jellybean, but i cant because my adb drivers are stuffed and ill figure that out later if need be.
I live in australia and the imei is fine, hasnt changed and im not even sure if that would effect the phone from functioning here. I have no idea is its affected the phones radio or frequencies if supposed to function on, help would be greatly appreciated.
I cant receive or make phone calls, texts messages, anything that relies upon me being connected to my carrier. everything else seems to work fine including my home internet. i also used that *#*#4636#*#* and that didnt really tell me anything i dont think.
Phone: Xperia x10i, unlocked
Running: android 2.3.3,
baseband version: 2.1.71
If you require any other information, ill post it up, not that sure what would be needed to figure this out.
Hi Everyone,
This is my first thread..I need some help with problem.....
My phone continuously restarts when it tries to find a GSM network. Phone has no issues with WIFI/Bluetooth as it perfectly works when the SIM is not inserted. It started when I was using my google maps and enabled GPS on my phone...the phone got heated up and shutdown...since then when ever i insert a SIM it restarts....but also during my experiments i found my phone is stable and accepts the SIM when its connected to a charger !!!!!
Steps Tried:
Reset settings and restore to factory defaults
Tried to repair with SEUS/ PC Companion
Update to ICS
Reinstalled ICS
Unlock boot loader, root and install CM10 nightly coconut
Tried a different SIM also different vendor.
Took phone to Sony service center they are unable to diagnose the issue
Any know any tshoot please help
Hi,
I bought a Lenovo A390 in January, a few weeks ago the phone started to lose signal on both sim cards, continued that way for a few minutes and returned to normal. After a few hours he lost the signal on both sim cards and didn't returned to normal, even after several hours. When I restarted the phone, it showed no sim card and the sound started to fail a little. Somehow, the cell returned to normal after several reboots.
I tried the factory reset, flashing a new rom, I even open the phone to see if any cable was loose, but the problem continues. I don't know what else to do, searching the internet I saw that several people had similar problems, but the solutions didn't work for me.
I took some screenshots to show the device when it loses signal and after rebooting.
Lenovo A390
Android 4.0.4
Baseband Version A510_MP_PCB_V1.0
Build Number A390_S320_130402
Please! Someone help me! :crying:
Same Problem
I am also facing a similar problem and in addition to that if I reboot with SIMs removed still it shows the old SIMs which were there before the problem happened.
Sometimes this workaround works and if the SIMs are not detected when removed, Next reboot with the SIMs and you can get the network (not all the time). ..
no imei no baseband

Greetings,
after I lost on my xperia m4 aqua signal and couldn't connect to any network I went to *#*#4696#*#* and checked if radio is on and modified networks to GSM/CDMA auto (PRL), I got it back for some time, but after that it stopped receiving any signal again. While searching around in menus I selected USA Band (the only one in menu, thought it is OK to click it, as there wasn't even back button -.- ), it still didn't work. I read on forum some users lost reception after changing band. After which I proceeded by flashing original firmware (I relocked bootloader and used Sony PC Companion), which didn't solve my problem. The next step I choose was to flash modem.sin using flashtool from firmware downloaded through xperifirm (for my country, my mobile and same operator), but I still cant connect to any networks and when I try to find any, even tho my IMEI is correct, but I receive message: "Error while searching for networks". I am now completely lost as to what to do next, so I created this thread in hopes of getting assistance solving this problem.
EDIT:
My sim card is working in other phones, but in this phone doesn't work any sim. 1st I lost LTE signal only and could use 3G, 2 days ago only EDGE was working, but now I can't get any signal. I wasn't doing any modifications to system in-between. Does it mean my antenna is probably dead?
As i have no idea how to attach files, I put all of them to my google drive shared folder and here is link (spaces inserted, hope mods wont get triggered and delete it):
