IM-A820L限制GSM，WCDMA上网的原理（其他泛泰机型可参考）7.13

定位到framework\com\android\internal\telephony\MMDataConnectionTracker.smali中

关键限制代码在isReadyForData()中

smali代码

    if-eqz v3, :cond_ec    iget-boolean v6, p0, Lcom/android/internal/telephony/MMDataConnectionTracker;->isDataConnPopupAllowed:Z    if-eqz v6, :cond_ec    iget-boolean v6, p0, Lcom/android/internal/telephony/MMDataConnectionTracker;->isDataConnDialogDisplayed:Z    if-nez v6, :cond_ec    sget-object v6, Lcom/android/internal/telephony/CommandsInterface$RadioTechnology;->RADIO_TECH_LTE:Lcom/android/internal/telephony/CommandsInterface$RadioTechnology;    if-eq v4, v6, :cond_235    invoke-virtual {p0}, Lcom/android/internal/telephony/MMDataConnectionTracker;->isRadioTechEvdo()Z    move-result v6    if-eqz v6, :cond_262    :cond_235    iget-object v6, p0, Lcom/android/internal/telephony/MMDataConnectionTracker;->datalock:Ljava/lang/Object;    monitor-enter v6    :try_start_238    const-string v7, "DATA"    const-string v8, "[MMDataConnectionTracker] isReadyForData is True and isDataconnPopupAllowed is True "    invoke-static {v7, v8}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I    const-string v7, "DATA"    new-instance v8, Ljava/lang/StringBuilder;    invoke-direct {v8}, Ljava/lang/StringBuilder;-><init>()V    const-string v9, "data conn popup showed, "    invoke-virtual {v8, v9}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;    move-result-object v8    iget-boolean v9, p0, Lcom/android/internal/telephony/MMDataConnectionTracker;->isDataConnDialogDisplayed:Z    invoke-virtual {v8, v9}, Ljava/lang/StringBuilder;->append(Z)Ljava/lang/StringBuilder;    move-result-object v8    invoke-virtual {v8}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String;    move-result-object v8    invoke-static {v7, v8}, Landroid/util/Log;->e(Ljava/lang/String;Ljava/lang/String;)I    invoke-direct {p0}, Lcom/android/internal/telephony/MMDataConnectionTracker;->createDataConnectionDialog()V    monitor-exit v6    goto/16 :goto_ec    :catchall_25f    move-exception v7    monitor-exit v6    :try_end_261    .catchall {:try_start_238 .. :try_end_261} :catchall_25f    throw v7    :cond_262    const/4 v3, 0x0    goto/16 :goto_ec

对应java代码

if (flag && isDataConnPopupAllowed && !isDataConnDialogDisplayed){int i4 = CommandsInterface.RadioTechnology.RADIO_TECH_LTE;if (i == i4 || isRadioTechEvdo())synchronized (datalock){int j4 = Log.d("DATA", "[MMDataConnectionTracker] isReadyForData is True and isDataconnPopupAllowed is True ");StringBuilder stringbuilder14 = (new StringBuilder()).append("data conn popup showed, ");boolean flag14 = isDataConnDialogDisplayed;String s4 = stringbuilder14.append(flag14).toString();int k4 = Log.e("DATA", s4);createDataConnectionDialog();}elseflag = false;}

可以看到

int i4 = CommandsInterface.RadioTechnology.RADIO_TECH_LTE;if (i == i4 || isRadioTechEvdo())

这个是关键判断，若非LTE或Evdo则flag=false;也就是不能上网

那么我们只需要去掉这个判断就可以了

也就是去掉这段对应smali代码

    sget-object v6, Lcom/android/internal/telephony/CommandsInterface$RadioTechnology;->RADIO_TECH_LTE:Lcom/android/internal/telephony/CommandsInterface$RadioTechnology;    if-eq v4, v6, :cond_235    invoke-virtual {p0}, Lcom/android/internal/telephony/MMDataConnectionTracker;->isRadioTechEvdo()Z    move-result v6    if-eqz v6, :cond_262

这样做之后，开机时便可看到弹出的是否使用数据的对话框了

7.13增加

启用设置中灰色的网络选项

修改Phone.apk\com\android\phone\Settings.smali

.method setEnabledAlwyasonMenu()V    .locals 2    .prologue    const-string v1, "alwayson_settings"    invoke-direct {p0}, Lcom/android/phone/Settings;->isRoaming()Z    move-result v0    if-eqz v0, :cond_0    const-string v0, "alwayson_settings"    invoke-virtual {p0, v1}, Lcom/android/phone/Settings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;    move-result-object v0    const/4 v1, 0x0    invoke-virtual {v0, v1}, Landroid/preference/Preference;->setEnabled(Z)V    :goto_0    return-void    :cond_0    const-string v0, "alwayson_settings"    invoke-virtual {p0, v1}, Lcom/android/phone/Settings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;    move-result-object v0    const/4 v1, 0x1    invoke-virtual {v0, v1}, Landroid/preference/Preference;->setEnabled(Z)V    goto :goto_0.end methodH

将上面19行的0x0改为0x1即可
