Disclaimer: I am not responsible if you brick your dashcam. I did all these tweaks to my dashcam and everything is working great for me.
I just want to say I did not come up with any of these tweaks, I am just putting them together in one place. for easier accessibility.
Remove the GoSafe 520 logo from your videos
Special thanks to Sunny for figuring this out and sharing it with the community. Here is his original post: https://dashcamtalk.com/forum/bookmarks/415/view-item
Removing the startup or shutdown chime / Higher bitrate
You need a few things things to accomplish this:
Ambarella Firmware Toolbox - http://dc.p-mc.eu/tools/a7tool
-Java is required
Firmware from Papago - http://us.papagoinc.com/products/gosafe-520/#support
1. Open up the AFT, go to Open -> A7 binary -> Open firmware.bin you downloaded from Papago
2. Partitions -> Extract all
3. ROM/RFS -> Extract ROM to disk
If you only want to change your bitrate and leave the startup chime, skip step 4 and continue to step 5
4. In the same folder you extracted firmware.bin you should see the folder "rtosfs"
Go into that folder and delete two files. ppg_poweroff_12k.pcm and ppg_poweron_12k.pcm
If you're finish and do not want to change your bitrate, continue to step 9
Thank you to rev90210 on YouTube for these steps. You could see his video on how to change bitrate here if you prefer a video over a text tutorial
5. Editors - > A5/A7 Bitrate editor
6. Load from PRI
7. Open PRI.a7s
8. Change the values for the resolution you're using. I personally record 2560x1080 and I set my bitrate to 21.0, I've seen some people go as high as 30. Thanks to mpmetro for the values.
9. ROM/FRS -> Build ROM from disk
10. Build -> Firmware update
You should now have a7firmware.bin, rename it to firmware.bin and flash it to your dashcam!
Edit your splash screen
If you want to edit your startup/shutdown splash screens the files are splash_papago_tw.jpg and logo_papago_tw.jpg. I did not care to mess with these so you're on your own there!
Custom sounds
If you're into custom sounds, I found that you could use Audacity http://audacityteam.org/ to edit pcm files. Go to File -> Import ->Raw Data...
I'm personally not into this, but I'm sure if you want you could figure it out. Just putting this information out there for reference.
If you brick your dashcam in the process, go to this thread to unbrick it

How to remove the yellow Papago 520 text?
What you have to do is this:
1. Take the card out and open logo.txt file. The stamp is in the logo.txt file in the card.
2. Delete Papago 520 text and replace it with a space.
3. Save the file.
4. Go to file properties and change it to 'Read only'. If you don't do this, camera will add that Papago 520 text when it starts.
5. Put the card in the camera and no yellow text.
Note: If you format, you have to do it again.
