LG G3 D855 loses signal continuosly saying error sim card

[Mr.Kiko]

Hello guys

Since few days, my LG G3 D855 loses signal everytime. After 5-10 minutes that it is turned on, it just doesn't receive any signal or it doesn't read my sim card. Sometimes it restarts continuously too saying it needs a working sim card.

I've this smartphone since an year and half and this is the first time I have this issue. I had CloudyG3 2.5. I tried to install a Marshmallow ROM and also a Lollipop stock rom with the same problem. I tried to flash few radios zips from here http://forum.xda-developers.com/lg-g3/general/radio-modem-lg-g3-t3110376 . It just works 10 minutes and then nothing. I performed a full-wipe from TWRP everytime I changed ROM. I tried a different SIM card but the issue happens identically.

Unfortunately I'm not an advanced user and maybe I'm doing something wrong so I really need your help guys. Due to that, I can't use this smartphone anymore.

Thank you

Thanks for your help!

I readed that topic but I'm a bit confused about the steps you've done

You flashed a Marshmallow rom with LG-D85530B-Flashable.Modem.RPM.TZ-AutoHybrid.zip this radio? And then you deleted LTEconfigs from system/apps ?
