Make a Nandroid Backup just in case, I'm not responsible if something messes up your phone.
FIX for AOKP, AOKPCB, ICS ,CM9 ,MIUI Sprint Phantom Vmail
ALL HAVE BEEN TESTED AND CONFIRMED WORKING BY ME ON LATEST VERSIONS OF THE ROMS AS OF 13 MAY
1. Go to 'Settings/Manage Apps' / Navigate to 'Phone' and press 'Clear data'.
2. Download attached -MoPhoPhantomVmailFix.zip for your CURRENT ROM.
(A) CM9_6.1-MoPhoPhantomVmailFix.zip for Jokersax's ICS/CM9
(B) MIUI_V4-MoPhoPhantomVmailFix.zip for Spleef/TH3BILL's MIUI V4 2.5.11
(C) AOKP_AOKPCB-MoPhoPhantomVmailFix.zip for Spleef's [AOKP Build 35] and [AOKPCB 20120513-0133] Rom Ports.
3. Make a NANDROID Backup your current ROM just in case.
4. In CWM (I used Jokers CWM-v3 for all 4 Roms) FLASH your downloaded Zip
(Zip clears Phone.apk's Dalvik Cache for you but you can also clear it manually)
5. In CWM, Go to 'Advanced' menu and 'Fix Permissions' and then 'Reboot System'.
6. Once booted up, open up Phone app, Navigate to its settings and in 'Voicemail Settings' CHANGE *86 to YOUR Mobile Number.
(STEP 7. Only for CM9) Uncheck 'Voicemail Notifications' checkbox to Disable, If not already Unchecked.
Then REBOOT your MoPho and enjoy
These Disable the persistent Ghost/Phantom Voicemail Notification & Icon that could only be removed by either clearing data in the phone app (and after every reboot), or the fix in which you can call Sprint to activate a dumb phone, leaving yourself a message and then clearing the voicemails, then reactivating your smartphone.
As you guys know, i search every devices sections, testing and trying out different mod's/apk's/zip's in hope that it would benefit us all, today i'd like to bring to you......Modified Phone.apk's which will get rid of the notification altogether, both the Icon and Notification in the pulldown menu.
*For those of you who have the Sprint VVM app installed or Use Google Voice for Vmail, this Mod wont mess up the Notifications for them.
**I CAN Confirm that Voice/Data/WIFI and Roaming work on Roms Mentioned above.
*** I DID NOT TEST TABLET-MODE FOR ANY OF THE ROMS WITH THESE MODIFIED PHONE.APK's SO PLEASE REPORT BACK.
Big thanks to the Sprint Samsung Epic Touch 4G & Sprint Galaxy Nexus sections, been pulling apps from almost all the Roms there to test different stuff out that would benefit us MoPho guys too and got these.
