LG Vu (CU920) Hacks

I recently purchased an LG Vu, and I'm always into making phones operate like I want to, remove all of the built in crap, and so on. If you read the rest of this post, I've got tons of stuff that I've been working on. It all requires BitPim, which I just emerge'ed in Gentoo. Install it however you need to. You have to tell BitPim that you have an LG VX-8700. I will leave it as an exercise to the reader to know to back up the files on their expensive piece of equipment before altering them...

LG Java Security Hack

This hack is the same on most every LG phone. Use BitPim to browse to /LGAPP/Media/Java/cert/. Save the .pol file in that directory. Open it in your favorite editor and find your provider's "Trusted Root CA" in the list of domains. It'll look like a LDAP distinguished name because that's what it is. Copy and paste all of the lines in that section, and paste them on top of the lines in the "domain: untrusted" section. Put that file back on your phone and you will be able to use all new applications without constantly authorizing network access. Currently installed applications will have to be reinstalled!

Remove Demo Applications

Browse to /LGAPP/Media/Java/ams/. Delete all of the Mxxx directories (for me, I stopped at M0012) and _folder_db_. Then, reboot the phone. Thanks to this forum for this tip.

Edit System Menus

Since I had just deleted Mobile E-Mail, I needed to get it off of the main screen or it would bug me. This turned out to be easy. Browse to /LGAPP/Media/Flash/ and download T1_en-UK.xml and T2_en-UK.xml. Open them in your favorite editor and remove the "Mobile E-Mail" item. You can delete but not add menu items. You'll have to reboot the phone to get it to reload the menu.

I'll be updating this blog post as I figure more stuff out about my phone.
