I have been recently obsessed with hacking my E815 again. My Previous E815 was replaced my Lockline Insurance who work with Verizon Wireless. After doing some Seem edits I noticed that instead of saying 1x next to my signal strength it now said EV. The EV stood for EV-DO or Evolution Data Optimized which is just another wireless standard that gives you internet speeds 2-3 times faster than the 1xRTT standard. The only downside to being stuck with using the EV-DO is that it sucks juice 2-3 times faster as well. To me having a longer battery life is more valuable to me than being able to connect to the internet on my phone faster. If I wanted to surf the internet I would find a computer! So anyway, I found a way to disable EV-DO altogether with my phone. Here are the instructions. Disclaimer: I am in no way responsible if you FUBAR your phone. This can/will void your warranty. Please take this into consideration before messing with your phone, especially if you don’t know what the hell you are doing!
Enable TEST MODE:
1. Hit the menu button
2. Quickly enter 073887*
-A dialogue box should open stating, “Enter Security Code:”, if not
retry steps 1-2.
3. Enter the Security Code
-Default code is 000000
4. Scroll to option “Test Mode” and select it
5. Choose “Enable” and exit to the main screen
Turn on TEST MODE and change settings
1. Hit the left soft key and the menu key simotauniously until a white screen appears with the letters “FTS” on top.
2. Hit the right soft key three (3) times
3. Scroll down to “HDR Pref:” and select “CDMA” with the right soft key
4. Scroll down to “HDR Hybr:” and select “off” with the right soft key
5. Push the left soft key and “EXIT”
6. Exit test mode by the same key combination as you did to enter it (left soft key and the center menu key.)
Power phone off then on.
Disable TEST MODE: Follow the same steps that you used to enable it.
Your phone should now only display 1x and no longer show EV indicator. USE GREAT CAUTION IN THE SETTINGS THAT YOU CHANGE! You can seriously mess your phone up by playing with the TEST MODE.
Another TIP:
I thought I’d share a little shortcut to make life a little easier when needing to access test mode:
1. Enter ##33284 (rapidly). If you did it properly, the ‘4’ won’t appear in the display. Test Mode access is now enabled.
2. Now press the menu key, followed by the left soft key. You are now in Test Mode, ready to do whatever changes you’re intending.
3. To end Test Mode, again press the menu key, followed by the left soft key (as you can see, it works as a toggle).
4. Test Mode access is still enabled, so it’s a good idea to shut it off. You do it the same when you enabled it (rapid pressing of ##33284).
This technique makes access a little faster and easier.
NOTE: When doing *228 (remote phone programming, which Verizon suggests to do at least once a month), Verizon will switch you back to EVDO. Again, if you don’t subscribe to the costly and useless VCAST service, there’s no reason to have EVDO enabled. Just follow the steps outlined above.
