Okay I'd Like to start off by saying I just made a simple to follow guide, FULL credit goes to SiXes and MikeDez for this hack.Credit to SiXes for announcing his findings.
Credit to MikeDez for announcing his testing results. This Hack allows you to bypass the 300kb ringtone file size limit for any ringtone that is assigned. This means that whatever ringtone you have set as default on your phone can be set to a ringtone that is larger than 300kb. I also included steps to change ringtones assigned to caller groups. For those of you who would like to use this hack to change the ringtones you have assigned to Caller Groups you must follow the method that places the ringtone into phone memory to make things easier, instead of using step #4b you would use step #4c.
Also this has only been tested on CU920 and TU915 phones so if you own a CU915 and attempt this hack please post your results.
Okay so here are the most simple methods to doing this:
To Use Phone Memory:1. First pick the audio file you would like to use as a ringtone. (make sure it is one of these formats: MP3, AAC Plus, WMA, AAC, EAAC+)
2. Find any audio file that is the same format as the file from step #1 and is also smaller then 300kb.
2b. Rename this file to match the audio file from step #1.
3. In EFS or BitPim navigate to /LGAPP/Media/Midis/RingTone/ and place the file from step #2 in that folder.
4. Disconnect and reboot phone.
4b. To change default ringtone go to Sound Settings>Ringtones and set the file from step #2 as your ringtone.
4c. To change Caller Group ringtone go to Address Book>Caller Groups>Select a Caller Group>Hit Options> Edit Group> Then as the ringtone select the file from step #2.
5. Reconnect your phone to EFS or BitPim and navigate back to /LGAPP/Media/Midis/RingTone/ and overwrite the file from step #2 with the file from step #1.
IMPORTANT: FILES MUST HAVE SAME EXACT NAME FOR THIS TO WORK6. Disconnect and reboot phone.
7. Enjoy!
To Use Memory Card:1. First pick the audio file you would like to use as a ringtone. (make sure it is one of these formats: MP3, AAC Plus, WMA, AAC, EAAC+)
2. Find any audio file that is the same format as the file from step #1 and is also smaller then 300kb.
2b. Rename this file to match the audio file from step #1.
3. Connect your to EFS or connect your phone to your computer in "Mass Storage" mode.
3b. If you are using EFS /mmc1/ is your memory card.
4. Select a location you would like to place this ringtone, for example "/mmc1/Audio/" in EFS or "X:\Audio\" in mass storage mode. ("X:\" being the letter of your phones drive on computer)
5. Place the file from step #2 into the folder location you chose in step #4.
6. On your phone Navigate to the memory card location you chose in step #4 select the file and hit
Options>Set As>Ringtone
7. On your Computer go back to the folder location from step #4 and overwrite the file from step #2 with the file from step #1.
IMPORTANT: FILES MUST HAVE SAME EXACT NAME FOR THIS TO WORK8. If you used EFS for this method then disconnect and reboot phone, if you were in "Mass Storage" for this method then simply disconnect phone from computer.
9. Enjoy!
Also Jennyb79 was kind enough to make a video tutorial on the memory card method, so here you go!:
