After the Android system is successfully flushed, the network signal is displayed as "no service ".

I believe that friends who play with Android phones will more or less like to use flash drives. However, after a variety of Rom, not everyone knows how to deal with small bugs. In this example, after the Rom is successful, the network signal of the mobile phone is always displayed as "no service", but the actual functions can be used normally, including making calls, the reason is that the contents of the SPNs configuration file are incorrect. Correction method is very easy, you can find the patch package in the Forum once again, if you have strong hands-on ability of friends can through the re manager directly into the/system/etc/spn-conf.xml, open with the editor, modify as follows.

<? XML version = "1.0" encoding = "UTF-8"?> <Spnoverrides> <! -- This is a list for operator specific SPNs. we will use below SPNs for instead if numeric is matched. format is listed as below: <spnoverrides numeric = "MCC + MNC" SPNs = "SPNs name"/> --> <spnoverride numeric = "46000" SPNs = "China Mobile"/> <spnoverride numeric = "46002" SPNs = "China Mobile"/> <spnoverride numeric = "46007" SPNs = "China Mobile"/> <spnoverride numeric = "46001" SPNs = "China Unicom"/> <spnoverride numeric = "46003" SPNs = "China Telecom"/> </spnoverrides>

After saving and exiting, restart the phone or switch the phone to the flight mode and exit again. Here we only list the configurations of China Mobile, China Unicom, and China Telecom that you are familiar with. If you want to find the configurations of other regions or countries, you need to find them on your own.

A smart friend can think that since it is text content, it can be modified at will. Yes, the numeric value is preset, but the value of the SPNs can be customized, you can change it to a more personalized phrase that you like. It must be cool. Make sure that you have the read and write permissions on the file. Otherwise, the modification is invalid.
