Adding custom entries in preferred network options - Android Q&A, Help & Troubleshooting

Are there any build.prop or system.prop edits to add preferred network options entries or and changes to add in device tree as I want to compile rom for my device g4 plus but all the roms have only 3g and lte of course *#*#4636#*#* is a workaround But I want to have it in the system settings.

Rom customization

hi how can we customize android on first boot. ie change settings to how we want, like enable data roaming, wifi settings. can this be done in a script in init.d folder? lots of settings are in databases so how can we change the values in them

Some things can be changed in /system/build.prop
Others in the init.rc and init.devicenamehere.rc, which are in the ramdisk. And some ROMs do have a init.d/*, but that's not standard AOSP.
Are you trying to change a running ROM or customize one for flashing?
For flashing a new own customized rom, how we can made roms, have ap2sd??? ( should we add anything special??
How can we add some new languages to rom..??
I need to add Arabic - persian just for supporting the characters but when I ad fonts to rom, it just shows them disconnected.. how can I fix this..??

[Q] Cyanogenmod Kernel Configuration Option To Specific File Map

Hello,
I am trying to build cyanogenmod kernel for an unsupported device. As I learned, the options for kernel build are in the file cyanogenmod_xxx_defconfig.
In that file you have to specify what config you have to use (for example CCONFIG_ARM=y , CONFIG_HAVE_PWM=y). I am experiencing some build problems because if I enable some options there are other config requirements for that for example CONFIG_BT_HCIUART_H4=y requires CONFIG_BT_HCIUART=y. If you build without that there is no clear way of showing you that you are missing that config option and you have to enable it. Sometimes it does say that something is undefined, so I have to search for that word in the sources, find the missing .h file, figure it out what option does it need in the config file (sometimes unsuccessful).
I belive if a map of the config options is available somewhere will greatly help adapting cyanogenmod for other unsuported devices.
for example
CONFIG_BT_HCIUART=y (uses files from kernel\drivers\bt\.... )
|
|---------- CONFIG_BT_HCIUART_H4=y (uses files from kernel\drivers\bt\....)
If you happen to know some documentation on these files will be greatly appreciated, eventually develop a custom tool for setting those options and dependencies.
Thank you for your time.

Hello, I will write about the standard application Dialer.apk in CM and LOS.
In many countries, the recording of calls is prohibited by law. Google, SM, LOS and others, just protect themselves from trouble:
- They in the Dialer.apk application have installed filters for countries and mobile operators, who can be recorded and who can not.
- Changed the libraries and again the problem kernel.
Okay the lyrics aside, go to work, what needs to be done:
1) Unpack the firmware or copy from the already installed, but we have the file Dialer.apk.
2) Decompile Dialer.apk.
3) On the path: Dialer \ res \ values ​​\ look for the file bools.xml
4) Using a text editor (preferably using Notepad ++ or something similar) open bools.xml
5) We search and check the line:
<Bool name = "call_recording_enabled"> true </ bool>
If instead of true it is written false ,change to true
6) Save the changes.
7) Next on the path: Dialer \ res \ values-mcc202 \ open the file bools.xml and edit the line:
<Bool name = "call_recording_enabled"> false </ bool>
Replace false with true
8) This line should be changed in all, from "values-mcc202" to "values-mcc505".
How many "values-mcc" , in so many countries is prohibited from recording a call!
Only after correcting all "values-mcc" , in the phone during the call to appear a choice for recording.
9) Compile (collect back) Dialer.apk
10) What to do with properly configured Dialer.apk, I think you know.
@toy_story: Thanks, do you know also a method to change the country detected by the phone?
Does it use the CSC?
If yes, can it be changed without change the ROM?

Hi, you could have done that before.
The record could be included by writing only 2 lines to the file "build.prop" or to install a suitable module for "Xposed"
Now if you take the application "dialer.apk" from LOS and from CM 13, it will be almost two different applications:
- change system libraries
- Enhance application security
- structure, location, and standard behavior
The control (check) is in 5 places, us for the time being limited to the easiest filter for the "MCC" country code.
And I think that a proven and well-working "Xposed" on android 7.1.? We will not see soon!

I mean another thing.
I'm not sure but there should be another memory somewhere to flash.
Correct me if I'm wrong but doesn't CSC survive a format of the /system partition?
When you flash LineageOS it should read the country somewhere in the phone (I think) since the ROM is the same for all countries.

Hi! No, you're wrong.
Yes, the disk is the same for all countries, but it already has different settings and behavior for different languages. Now when installing "LOS Pom" , the system automatically determines where we are (installation language), before this was not.
Behavior for countries is recorded in the form of a blacklist, according to the qualifications of "MCC" and "MNC".
MCC (Mobile Country Code) - the mobile country code in combination with MNC is the unique identifier of the cellular operator of GSM, CDMA, iDEN, TETRA and UMTS networks, as well as some satellite communication operators. ITU-T Recommendation E.212 defines mobile country codes.
MNC (Mobile Network Code) - the mobile network code in combination with MCC is the unique identifier of the cellular operator of GSM, CDMA, iDEN, TETRA and UMTS networks, as well as some satellite communication operators. ITU-T Recommendation E.212 defines mobile country codes.
Example:
Next on the path: Dialer \ res \ values-mcc202 \ open the file bools.xml and edit the line:
<Bool name = "call_recording_enabled"> false </ bool>
"Mcc202" - country code Greece
"Bools.hml" - with the parameter > false <
If we do not change to > true <
Then with this "POM" in the territory of Greece, the recording of the call will not work.
Previously, without modifying the "POM" workaround, the "modules" for "Xposed" were made.

I have installed it without SIM.
Before installation I have wiped system, data, cache (almost everything).
How can it detect country?
How can I verify what country is detected?

Yes, I agree. Without a SIM card and without an Internet connection, applications will not determine in which country you are.
But you still insert a SIM card and will be connected to the Internet!
As soon as you insert the sim, the cellular operator will immediately tell your phone which country you are in.
Hi,
I just made a test with a fresh install of lineage-14.1-20170322-nightly-i9100-signed.zip, gapps pico with TWRP.
I installed Fix_addonsu-arm-signed.zip without errors, but the phone is still not rooted.
Any ideas what is going on?
As far as i remember last time i rooted it i had to use CWM-SuperSU-v0.97.zip too.
Thanks!
Edit: Please, ignore the above zzzz - i simply forgot to assign root rights to adb+apps in developer settings.

[Guide] Enabling "SIM management" or "The hability to disable one SIM" for dual SIM

[Guide] Enabling "SIM management" or "The hability to disable one SIM" for dual SIM
As I did not find any documentation on the subject on XDA, I thought it shoud be useful to explain how to enable this feature when building a ROM.
There is nothing complicated as it's totally implemented in Android (starting in Android 8), you just have to configure your build on the device side to use some implementation. It's mainly around the "qti-telephony-common" library that you can find here : https://github.com/LineageOS/android_hardware_lineage_telephony
So here are the main steps :
Edit your device.mk (in device/<brand>/<phone) to specify that you will use this library
To do so you only have to add these lines (be sure to remove all references to qti-telephony-common and telephony-ext)
Code:
# Radio
PRODUCT_PACKAGES += \
qti-telephony-common
PRODUCT_BOOT_JARS += \
telephony-ext
If it's not already in the tree of the ROM, you may have to clone the library from github (for example Lineage automatically clones it)
You can clone https://github.com/LineageOS/android_hardware_lineage_telephony in the directory of your choice in the device tree, the Android.mk file will be automatically detected by the build
Build your ROM and "voilà"
Hope it helps
Hi adinechin! It seems that you are quite expierienced in adroid so probably you can help me. Can you please tell me if there is any way to enable dual SIM dual standby mode working on pixel 3xl? Ive flashed Android 10 beta 5 on my pixel 3xl and it works fine but starting from beta 6 Google excluded this possibility for pixel 3xl. Changing property persist.vendor.radio.multisim_switch_support equal TRUE doesn't work on newer versions on Android 10/11. Thanks in front!

[HOWTO] Customizing the stock Android 8.0 Oreo on the Japanese Xperia XZ1 with temproot

Carrier phones are odd-ball siblings of their global counterparts. As such, they do not enjoy nor receive the same level of support as that of the latter in the modding scene (custom ROMs, recoveries, etc.), even though both carry the same brand model name, e.g. Xperia XZ1 G8341 "Global" vs. Xperia XZ1 SO-01K "NTT DoCoMo". This is because of the subtle underlying hardware differences between the global and carrier variants, even if they have the same specsheet.
One can try flashing ROMs for a global variant onto one of these phones, but it can be a hit or miss, with some hardware components not working like NFC and even losing other functions like the fullseg receiver. And even if it seems to run fine, there may be other issues like poor battery performance because of a non-functioning hardware preventing deep sleep.
Given the above, if you're like me who has one of these carrier phones and doesn't mind running stock where everything works, then this guide is for you. This will allow you to customize several aspects of the system as indicated per section.
This guide has been made possible with the great work of @j4nn on his temproot exploit via CVE-2019-2215 here, extended to support carrier phones from NTT DoCoMo, au KDDI, and Softbank. Once you achieve temporary privilege escalation by running bindershell, you can execute the following commands from inside a terminal emulator (if you followed the howto from the link) or the adb shell. There is no need to setup Magisk. All changes are permanent, except for those in /data that will be erased upon factory reset.
Keep in mind the following:
1. Customizations in this guide were done on an Xperia XZ1 SO-01K from NTT DoCoMo. I think that the file system from the other carriers shouldn't differ that much, but let me know if there are any discrepancies and I'll see if I can help.
2. Make backup of the files if you wish to revert them later on.
3. Avoid making changes in files and/or directories other than those as detailed in this guide, specifically in /oem and /data.
4. The starting directory for files to be copied is assumed to be at /sdcard, i.e. the root directory of the internal storage.
5. Always remount as read-write before committing the changes in /oem:
Code:
# mount -o rw,remount /oem
6. Restart the phone for changes to take effect.

}
Let's get started.
• Boot animation
Shave off a few seconds of boot-up time by removing the boot animation, or you can replace this to whatever you want (you'll have to make sure that the boot animation is in compatible format with the phone). To remove:
Code:
# cd /oem/media
# rm bootanimation.zip
# touch bootanimation.zip
# chmod 644 bootanimation.zip
It is not enough that you delete the file, because then the system will load /system/media/bootanimation.zip. You need to create a zero-byte file with the proper permissions.
• Boot logo
I found an empty splash partition that is 32.64 MiB in size. I'm still trying to figure out if flashing a compatible boot splash image to this partition will make the bootloader load this image instead of the one built into it, just like in the case of the boot animation above. I still have to determine the compatible format for this splash image.
If you have further information regarding the format please share it here. I'm also trying to change the blinding light of that boot logo to something more tolerable.
• Emoji font
Fast fact: Did you know that emoji comes from the Japanese words 'e' meaning picture and 'moji' meaning character?
To replace (assuming you have a font file named MyFont.ttf):
Code:
# cd /oem/fonts
# rm ColorUniEmoji.ttf DcmColorIEmoji.ttf
# cp /sdcard/MyFont.ttf ColorUniEmoji.ttf
# chmod 644 ColorUniEmoji.ttf
The two ttf files are referenced in /system/etc/fonts.xml, but it is the ColorUniEmoji.ttf file that needs to be replaced to make changes to the system emoji. Removing this file will only defer the system to load all glyphs from /system/fonts/NotoColorEmoji.ttf, so rename your font file accordingly.
• Display font
To have your own font apart from the choices in Settings > Display > Change font for display (assuming you have a font file named MyFont.ttf):
Code:
# cp /sdcard/MyFont.ttf /data/system/fonts/UserFont.ttf
• Installing apps into /system
You can achieve the same effect of installing apps into /system (without triggering the 'Your device is corrupt' boot message) as follows (assuming you have an app named MyApp.apk):
Code:
# cd /oem/app
# mkdir MyApp
# chmod 755 MyApp
# cp /sdcard/MyApp.apk MyApp/
# chmod 644 MyApp/MyApp.apk
Replace /oem/app with /oem/priv-app as needed.
• Debloat
Effortlessly debloat your phone from carrier-specific apps and services by making modifications in /oem/android-config/early_config.xml. The package names contained in the xml file will disappear from the system upon restart. A factory reset will not even bring those packages back. You can remove the package names should you decide to have the need for them. Restart the phone and they will appear again.
Here's mine configured with the bare-minimum packages to avoid bootloops and other issues. You can change it to suit your needs, just follow the file structure. I purposefully didn't indent the lines I added to easily see them.
You can also rename or delete the folder /oem/deletable-app if you don't want to have those apps contained therein to be installed by the system upon a factory reset.
Note for SO-01K:
Do not include the com.nttdocomo.android.phonemotion package if you use the stock phone dialer com.sonymobile.android.dialer. The dialer will crash whenever you receive an incoming call, preventing you from answering it.
• GPS
UPDATE: The GPS doesn't work no matter what parameters are changed in the gps.conf file. It doesn't detect any satellites, so it doesn't lock-in on your coordinates, at least this is the case with mine. This may be another limitation of using a carrier-locked phone outside of it's country of origin. I'm afraid that the only remedy for this would be to flash a global ROM variant, especially if binaries are involved. I know this to be the case because I have an SOV37 on Japan ROM and no GPS work there also, but after flashing it to a Global ROM then I got GPS to work properly.
I'm still trying to find out how to fix this without unlocking the bootloader, but I'm not holding my breath.
Tweak the GPS parameters of the phone in /oem/android-config/gps.conf.
• Preset networks
Remove /oem/android-config/preset_networks.conf if you don't want to have carrier saved networks present whenever you reset your network settings or factory reset.
• APNs
I have always wondered why carrier phones don't automatically populate the APN for any SIM other than a Japanese SIM, even after having the phone SIM unlocked. As it turns out, the system of these phones doesn't really include the APN parameters of other networks outside Japan.
/system/etc/apns-conf.xml, which is where all APN parameters for all networks of the World can be found, is a symlink to /data/customization/apns-conf.xml, which itself is another symlink to /system/etc/customization/settings/defaults/apns-conf.xml, which is an xml file containing zero APN parameters.
As you can see, we can change this by replacing the symlink in /data/customization/apns-conf.xml with the full xml file from Google's source repository found here. This will download a file named apns-conf-full.txt. This is base64 encoded. To decode:
Code:
$ base64 -d /sdcard/Download/apns-conf-full.txt > /sdcard/apns-conf.xml
Unfortunately, upon every restart the system reverts /data/customization/apns-conf.xml to the original symlink. To prevent this, we need to make the file immutable with chattr, but this command is not available in the system.
If you followed the howto from the temproot link, and ran bindershell from a terminal emulator, you will come across the post of @Tifs detailing on how to successfully start Magisk from the same. You just need to download the arm64/busybox binary from one of the posted links.
When you have this and the xml files ready, then:
Code:
# cd /data/local/tmp
# cp /sdcard/Download/busybox .
# chmod +x busybox
# cd /data/customization
# rm apns-conf.xml
# cp /sdcard/apns-conf.xml .
# chmod 644 apns-conf.xml
# /data/local/tmp/busybox chattr +i apns-conf.xml
After restarting the phone, try Settings > Network & Internet > Mobile network > Access point names > Reset to default and see the available APNs for your SIM.
• VoWiFi / Wi-Fi calling
These carrier phones came provisioned with VoLTE and Video Calling but not Wi-Fi calling, at least in the case of mine. I'm not sure how useful Video Calling would be outside Japan, and it seems that Wi-Fi Calling is not used there. @pbarrette provided a great overview of the configs that enable VoLTE and Wi-Fi Calling here. But we are interested in enabling Wi-Fi Calling so here are the relevant changes to make:
1. Decompile /oem/overlay/com.android.carrierconfig-res-305.apk on your phone or PC.
2. Once decompiled, modify res/xml/vendor.xml with the following values as follows:
Code:
<boolean name="carrier_wfc_ims_available_bool" value="true" />
<boolean name="carrier_default_wfc_ims_enabled_bool" value="true" />
3. Rebuild the decompiled apk and overwrite the original file with the modified one.
4. Append the following line to /oem/system-properties/config.prop:
Code:
persist.data.iwlan.enable=true
5. It may be necessary to change/reinsert SIM after phone restart for the changes to take place.
• Build.prop
It is not possible to add or modify values in /system/build.prop without triggering the 'Your device is corrupt' boot message. However, you can add or modify certain values in /oem/system-properties/config.prop, which gets read into the system property database.
If you are using Gboard and you want custom themes for it, then you can append these lines for example:
Code:
ro.com.google.ime.themes_dir=/oem/etc/gboard_theme
ro.com.google.ime.theme_file=swiftinstaller.zip
Edit the values as needed.
Here are the other interesting values to modify:
Code:
# show the NFC icon
ro.nfc.icon.enable=true
# disable the forced camera shutter sound
ro.camera.sound.forced=0
It may also be necessary to decompile /oem/overlay/android-res-305.apk, then modify res/values/bools.xml as follows:
Code:
<bool name="config_camera_sound_forced">false</bool>
to turn off the forced camera shutter sound. I did both modifications, but try the config.prop value first. It may be enough.
* VoLTE / 4G calling
There should be a matching APN entry to use VoLTE with your network operator. Unfortunately, this is missing as well, and if you try to add it manually in Settings > Network & Internet > Mobile network > Access point names, it doesn't get saved. This is the case with mine.
UPDATE: I just acquired an Xperia XZ2 SOV37 "au KDDI" running Android 10. When I tried adding an APN of type 'ims' there, I got an 'Operator does not allow adding APNs of type dun, ims.' So it is a carrier-imposed restriction on the phone, only that in my XZ1 it fails silently.
You can add the APN entry in two locations:
1. /data/customization/apns-conf.xml, but you can only do this before making the file immutable; or
2. /oem/overlay/android-res-305.apk, by decompiling it and then modifying res/xml/apns.xml, rebuild and then overwrite with this one. I went this route.
In both cases, this is the APN entry you need to add:
Code:
<apn carrier="IMS" apn="ims" mcc="{mcc}" mnc="{mnc}" type="ims" protocol="IPV4V6" roaming_protocol="IP" />
Replace the values in curly braces with the MCC and MNC of your network operator.
* CellBroadcastReceiver
Each carrier phone comes with their own way of receiving emergency alerts depending on the network operator. All of them however don't include the CellBroadcastReceiver app like the other models do.
If you want to receive such alerts, then download this apk here. Rename it as CellBroadcastReceiver.apk then do the following:
Code:
# cd /oem/priv-app
# mkdir CellBroadcastReceiver
# chmod 755 CellBroadcastReceiver
# cd CellBroadcastReceiver
# cp /sdcard/CellBroadcastReceiver.apk .
# chmod 644 CellBroadcastReceiver.apk
* Sound enhancement
Sound enhancements like the DSEE HX, ClearAudio+, etc. apply only on stock media players like the Music and Video player (but not on any other else it seems) in the case of Android 8.0 Oreo. On Android 9.0 Pie, these enhancements apply system-wide for all media playing apps. An upgrade is recommended if this customization is needed.
While customizations such as these may not come close to the level you get with custom ROMs (and the updated software and security that come with it), these will at least give you something to control and tweak AND STILL get a device with a locked bootloader (and all the goodies that come with it like passing SafetyNet and Key Attestations, Widevine L1, intact DRM keys, etc.). You get the best of both worlds, at the cost of running a not-so-updated system.
I will add more sections to this as soon as I made some more modifications. I hope you find this guide useful as much as I enjoyed creating it. If you do, please hit the LIKE button. It will be very much appreciated.

Thanks a lot for such a helpful post.
I have a SO-02K XZ2 Compact docomo, running android 9.0, unlocked bootloader, rooted.
I could not find file "apns-conf.xml" on "/system/etc/".
After rebuilding "android-res-305.apk" ... each time i tried to manually add APN (through Newtrok & internet > Mobile network > Advanced > Access Point Names) i end up with no APNs.​
what could be wrong?

Hi, sorry for the very late reply, I must have missed the notification for this one.
If you read my post carefully, then you would have already gotten the answer to your question.
I'm not sure what you did after rebuilding the file, but if you followed my post correctly then you wouldn't have the need to manually add an APN entry for VoLTE, which doesn't get saved.
@braveheartleo regarding 4g/volte I tried to modify the apns-conf.xml. I managed to have ims registered but for some reason, after a while it reverts back to not registered even though i made it immutable. I would like to try the other way by decompiling android resapk but I don't know how to. Do you mind sharing a basic guide and the pre requisites. I tried recompiling in windows using apktool and I don't know if I'm doing it right, I didn't see any res folder after inside. I tried the apk tool on the go but I'm not lucky to have it installed, I think the development of the app has stopped years ago. I have sov36 so I am also thinking maybe it's deferent on how you do it compare to softbank?

@braveheartleo I managed to decompile android-res-305.apk but there is no res folder or apns.xml on it for sov36 au. I tried to look onto the same apk for s0-01k and it is present. I guess docomo build their firmware a bit different than kddi au. I tried modifying apns-conf.xml and i get ims registered but i still can't make calls. And after a while it reverts back to not registered even after making it immutable.

I also want to add that they can easily debloat by flashing global rom and still have temp root. It worked on my xz1 au/sov36.

I just want to point that flashing global rom will loose the volte. But I have found a solution for that or maybe others already knew about it. By modifying oem/system-properties/config.prop and adding these lines and not justnthe volte but it will also activate wifi calling and video calling.
