[Fix] Wifi Fix for ivanich's CyanogenMod

[jinxul]

hi,
well, as you know there is problem with CyanogenMod(and some other aosp roms) wifi in some countries and the problem is due to wifi_country_code value inside global database.
so after reading HTCZ715E amazing guide i made this flashable zip for those who still have problem with wifi in ivanich's CyanogenMod.


Installation

• flash it via recovery(no need to wipe)

Credits:
@ivanich for his awesome rom

@jinxul if it's only related to the record in the global table of settings storage database, I thought, wouldn't it be easier to use an init.d script with an addon.d script?

For example:

#!/system/bin/sh

# Set wifi country code
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "update global set value=nz where name='wifi_country_code';"

the main problem is in the telephony-common.jar. every time that wifi turns on framework will rewrite the record on its own... so framework has to be patched(and all that will do is to stop rewriting wifi_country_code on every time wifi turns on).
i also put an script in the zip(similar to this) to change the value back to null but that's just for those who don't want to wipe their data(cause its wont work if there is already a value for wifi_country_code)

so init.d wont do anything as long as framework isnt patched.

I thought that but when I changed mine to 'us' and toggled wifi on and off a few times and connected to network it didn't revert back for me. I tried 'uk' too but couldn't find any networks when turning wifi on.

reboot is required when you change it manually.. system wont just read it like that unless you tell it to do so, and you cant do that with sqlite3. you need an app/service with WRITE_SETTINGS permission (android.permission.WRITE_SETTINGS).

Let me chime in:

Similar Wi-Fi issues have been persistent across my previous two devices running Android 5+. Setting the Wireless channel of your network to 11 or below (U.S. standard) fixed it. If you don't live in a too dense area - eg. have free uninterfered channels in that scale - then I suggest using those. EU channels (12,13) break far too often due to this specific issue which seems either upstream or hardware-specific. To your information, the three (with this) tested devices all have BCM4329 Wireless modems.

If anyone tries this instead, let me know if it worked here as well.

1. unzip the rom, replaced it then zip it. it should do the job.
2. sure.. which one is it?(cm11 or 12)
